Translating and establishing the psychometric properties of the Jenkins Sleep Scale for Arabic-speaking individuals.

BACKGROUND: The Jenkins Sleep Scale is a widely used self-report questionnaire that assesses sleep quality and disturbances. This study aimed to translate the scale into Arabic and evaluate its psychometric properties in an Arabic-speaking population. METHODS: The Jenkins Sleep Scale was translated into Arabic using forward and backward translation procedures. The Arabic version was administered to a convenience sample of 420 adults along with the Pittsburgh Sleep Quality Index (PSQI) and Athens Insomnia Scale (AIS) for validation purposes. Reliability was examined using Cronbach's alpha and McDonald's omega coefficients. Confirmatory factor analysis (CFA) was also conducted to test the unidimensional factor structure. Convergent validity was assessed using correlations with PSQI and AIS scores. RESULTS: The Cronbach's alpha and McDonald's omega values for the Arabic Jenkins Sleep Scale were 0.74 and 0.75, respectively, indicating good internal consistency. The 2-week and 4-week test-retest intraclass correlation coefficients were both 0.94 (p < 0.001), indicating excellent test-retest reliability. The CFA results confirmed the unidimensional factor structure (CFI = 0.99, TLI = 0.96, RMSEA = 0.08). The measurement model had an equivalent factor structure, loadings, intercepts, and residuals across sex, age, and marital status. Significant positive correlations were found between the Arabic Jenkins scale score and the PSQI (r = 0.80, p < 0.001) and AIS (r = 0.74, p < 0.001), supporting convergent validity. CONCLUSION: The Arabic version of the Jenkins Sleep Scale demonstrated good psychometric properties. The findings support its use as a valid and reliable measure for evaluating sleep quality and disturbances among Arabic-speaking populations.

The translation and validation of the surgical anxiety questionnaire into the modern standard Arabic language: results from classical test theory and item response theory analyses.

BACKGROUND: Preoperative anxiety is commonly found in patients who are waiting for surgery and can lead to negative surgical outcomes. Understanding the sources of surgical anxiety allows healthcare providers to identify at-risk patients and implement psychosocial interventions such as counseling, relaxation techniques, and cognitive‒behavioral therapy to minimize anxiety. Few comprehensive psychiatric measures are available to assess preoperative anxiety in Arabic. OBJECTIVE: Our study aimed to translate, adapt, and validate the Surgical Anxiety Questionnaire (SAQ) into the modern standard Arabic language, also known as Fusha al-Asr Arabic. METHODS: To translate the questionnaire, the research team used the gold standard process of forward translation by two independent translators along with back translation evaluation by four trained medical doctors. A cross-sectional study was conducted using an online survey completed by 208 Arabic speakers (mean age 38 years, 44% women) from four countries. Psychometric analyses, which included internal consistency, test-retest reliability, convergent validity, confirmatory factor analysis, and item response analysis, were performed. Convergent validity tests were performed against the Generalized Anxiety Disorder 2-item Scale (GAD-2), Patient Health Questionnaire-4 (PHQ-2), Perceived Stress Scale 4 (PSS-4), and Arabic version of the Visual Analog Scale for anxiety (VAS-A). RESULTS: The mean SAQ of our sample was 19.38 ± 12.63 (possible range 0-68). The Arabic SAQ translation demonstrated excellent internal consistency, with McDonald's omega and a Cronbach's alpha of approximately 0.90. The test-retest reliability was also high, with an intraclass coefficient of 0.94. The SAQ showed strong convergent validity against the GAD-2 (r = 0.94, p < 0.01). The SAQ also showed weak-moderate correlations with the PHQ-2 (r = 0.26, p < 0.01), PSS-4 (r = 43, p < 0.01), and VAS-A (r = 0.36, p < 0.01) scores. The original three-factor structure was supported by confirmatory factor analysis, confirming the original structure reported in the original English language version. The results for fitness indices showed acceptable preliminary results (CFI/TLI approximately 0.90), and deleting some items improved the model fit (CFI/TLI > 0.90, RMSEA < 0.08). We suggest retaining the original factorial solution until further validation studies can be conducted. The item response theory (IRT) results identified no items that were excessively difficult or subject to guessing. The multidimensional IRT provided evidence that the SAQ items form a multidimensional scale assessing surgical anxiety that fits the classical model reasonably well. CONCLUSION: The SAQ has demonstrated acceptable reliability and validity; thus, it is a trustworthy and valid tool for evaluating preoperative anxiety in Arabic speakers. Future research could benefit from using the SAQ in both surgical and psychiatric research.

Examining the reliability and validity of the arabic version of the Glasgow Sleep Effort Scale (GSES).

BACKGROUND: Sleep effort refers to the cognitive and behavioral exertion involved in initiating and maintaining sleep. High sleep effort is increasingly recognized as perpetuating insomnia and poor sleep quality. Validated sleep effort scales enable the quantification of this construct in clinical and research settings. However, no Arabic version has been available. This study translated and validated the Glasgow Sleep Effort Scale (GSES) into Arabic to assess sleep effort in Arabic-speaking populations. METHOD: The GSES was translated into Arabic using the forward-backward translation approach. This involved an initial Arabic translation from the source followed by a back translation into English to ensure accuracy. A total of 369 participants were recruited to assess the psychometric properties of the Arabic version of the GSES, specifically its reliability and validity. The reliability analysis included Cronbach's α, McDonald's ω, and test-retest reliability. Validity was examined using confirmatory factor analysis (CFA) to evaluate the unidimensionality of the scale and assess model fit. Convergent validity was also assessed through correlation analysis with the Athens Insomnia Scale (AIS) and the Generalized Anxiety Disorder-7 Scale (GAD-7). RESULTS: The Cronbach's α reliability coefficient and McDonald's ω for the scale were found to be 0.87 (95% CI: 0.85-0.89). The test-retest reliability was 0.95 (95% CI: 0.93 - 0.97) after two weeks. The one-factor model showed an acceptable fit, with a CFI of 0.96, a TLI of 0.94, and an SRMR of 0.04. Invariance analysis revealed that male and female participants conceptualized and responded to the GSES items similarly, without differences in factor loadings or scale characteristics between the sexes. The Arabic version of the GSES has good convergent validity, as shown by the significant correlation between the AIS and the GSES (r = 0.72, p < 0.001). Similarly, the GAD-7 score was significantly correlated with the GSES score (r = 0.77, p < 0.001). CONCLUSION: This is the first study in which the GSES was validated in Arabic. This allows the scale to reliably gauge sleep effort among Arabic speakers, providing new clinical and research opportunities to understand how maladaptive sleep effort may contribute to insomnia and suboptimal sleep in this demographic population.

The prevalence and risk factors of screen-based disordered eating among university students: a global systematic review, meta-analysis, and meta-regression.

PURPOSE: The purpose of this review was to estimate the prevalence of screen-based disordered eating (SBDE) and several potential risk factors in university undergraduate students around the world. METHODS: An electronic search of nine data bases was conducted from the inception of the databases until 1st October 2021. Disordered eating was defined as the percentage of students scoring at or above established cut-offs on validated screening measures. Global data were also analyzed by country, research measure, and culture. Other confounders in this review were age, BMI, and sex. RESULTS: Using random-effects meta-analysis, the mean estimate of the distribution of effects for the prevalence of SBDE among university students (K = 105, N = 145,629) was [95% CI] = 19.7% [17.9%; 21.6%], I2 = 98.2%, Cochran's Q p value = 0.001. Bayesian meta-analysis produced an estimate of 0.24, 95% credible intervals [0.20, 0.30], τ = 92%. Whether the country in which the students were studying was Western or non-Western did not moderate these effects, but as either the mean BMI of the sample or the percentage of the sample that was female increased, the prevalence of SBDE increased. CONCLUSIONS: These findings support previous studies indicating that many undergraduate students are struggling with disordered eating or a diagnosable eating disorder, but are neither receiver effective prevention nor accessing accurate diagnosis and available treatment. It is particularly important to develop ever more valid ways of identifying students with high levels of disordered eating and offering them original or culturally appropriate and effective prevention or early treatment. LEVEL OF EVIDENCE: I, systematic review and meta-analysis.

Association between mass media and body weight concern among Jordanian adolescents' residents of Amman: the role of gender and obesity.

OBJECTIVES: Body image in the mass media promotes an unrealistic picture of body shape that leads to body dissatisfaction among adolescentsQuery. Therefore, the study presented in this paper aimed to assess the association between mass media and adolescents' weight concerns and perceptions of body weight and shape. METHODS: A cross-sectional survey was conducted on school adolescents aged between 15 and 18 years during the academic year 2013-2014. Multistage stratified sampling method was used. The number of participants in the study was 795 students: 400 boys and 395 girls. RESULTS: All participants have a common behavior in rarely reading magazines, but they spend more than 2 h in watching television or less than 3 h using the internet. However, most of obese/non-obese adolescents, boys or girls, have shown high influence (p < 0.05) of reading magazines on the subject of dieting to lose weight. CONCLUSION: While obese students read more magazines on dieting to lose weight, other mass media did not show the same results on weight concerns and body shape among Jordanian adolescents.

An Umbrella Review and a Meta-analysis of Meta-analyses of Disordered Eating Among Medical Students.

Objective: To prevent eating disorders in future physicians, this umbrella review and meta-analysis of previous meta-analyses estimates the prevalence of disordered eating (DE) among medical students worldwide and identifies key risk factors. Methods: Four databases were searched electronically between their inception and February 1, 2023. The search was later updated to December 31, 2023. Results: The search yielded prevalence rates for medical students who scored above established cutoffs on validated assessment measures for DE. These were computed to provide an overall pooled estimate. The data was taken from 2 previous reviews. Both these systematic reviews found a 15.1% (95% confidence interval [CI]: 14.7%-15.6%) prevalence rate of DE among medical students. The equivalent Hedges' G = 0.30 (95% CI: 0.29-0.31), the equivalent odds ratio = 1.74 (95% CI: 1.71-1.77), I2 = 97.6%, and the excess of statistical significance is P = .001. The trim and fill adjusted effect size was 16.0% (95% CI: 14.0%-20.0%). Conclusion: Because eating disorders put students' safety and well-being at risk and because the health of early-stage physicians is vital to the welfare of a country, early signs of disordered eating must become a priority of medical schools and a signal for effective prevention and intervention. The recommendation is to ensure supportive environments, provide easy access to effective care, and hold clear expectations for student eating behavior.

Junior athletes' nutritional demands: a narrative review of consumption and prevalence of eating disorders.

Information regarding the dietary requirements and consumption of young athletes is limited. Hence, the aim of this narrative review is to provide a comprehensive combination of research and review papers on the nutritional status of young athletes aged 5-18 years old, as well as quantitative, qualitative, wholesome foods, food choices, and eating disordered data concerning the dietary requirements for growing young athletes. This study involved systematic searches of electronic databases, including Google Scholar, PubMed, Science Direct, Scopus, and Web of Science. The specific criteria for identifying research papers published in English from July 1980 until May 2024 were included. Only 48 studies out of 1,262 were included in this narrative review. The findings of this study suggest that, compared with adults, junior athletes need a unique approach to meet their dietary needs. Growth, development, and general athletic performance depend on macronutrients, as they are vital nutrients for young active athletes. However, research on enhancing junior athletes' performance is still in progress, and studies on hydration status, and eating disorders are limited.

Development and Validation of a Food Frequency Questionnaire for Evaluating the Nutritional Status of Patients with Serious Mental Illnesses (DIETQ-SMI) in Bahrain.

General food frequency questionnaires (FFQs) have not been tailored for or validated in individuals with psychiatric disorders. Given the unique eating behaviors of patients with serious mental illnesses (SMIs), custom-made tools are needed. Therefore, we developed and validated an FFQ customized to individuals with SMIs. A total of 150 adults with SMIs (schizophrenia, bipolar disorder, or major depression) were recruited from Bahrain. The participants completed the 50-item Dietary Intake Evaluation Questionnaire for Serious Mental Illness (DIETQ-SMI) FFQ and a 3-day food record (FR). The validity of the FFQ was assessed by comparing nutrient intake to FR intake using correlation and reliability statistics. The DIETQ-SMI demonstrated a good ranking validity compared to the FR based on correlation coefficients (rho 0.33 to 0.92) for energy and macro- and micronutrients. The FFQ had high internal consistency (McDonald's omega = 0.84; Cronbach's alpha = 0.91) and test-retest reliability (ICC > 0.90). The FFQ tended to estimate higher absolute intakes than the FR but adequately ranked the intakes. The FFQ value was correlated with the FR for all the items (p < 0.001). The DIETQ-SMI is a valid and reliable FFQ for ranking dietary intake in individuals with an SMI. It can help assess nutritional status and, subsequently, guide interventions in high-risk psychiatric populations.

The psychometric properties of the Arabic version of the dieting beliefs scale (DBS).

Background: There are relatively few data about the association between locus of control and weight loss in Arabic populations. A tool does exist, the Dieting Belief Scale (DBS), that was designed to measure individuals' beliefs regarding their ability to control their body weight. The aim of this study was to translate this tool into Arabic and to evaluate its psychometric properties. Methods: The forward translation of the DBS from English to Arabic was completed by two professional bilingual translators, while the back translation from Arabic to English was independently performed by another two different professional bilingual translators. An online survey using the tool was then completed by 245 participants, fully aware of the study's purpose. Psychometric analyses were subsequently conducted to assess the reliability and validity of the Arabic DBS.Internal consistency was examined using Cronbach's α and McDonald's ω coefficients. Test-retest reliability was also assessed. Confirmatory factor analysis was employed to evaluate the fit of a three-factor model, with indices including Comparative Fit Index (CFI), Tucker Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA), and Standardized Root Mean Square Residual (SRMR). Convergent validity was assessed by examining the correlation between the Arabic DBS and the Eating Attitude Test (EAT-26) previously translated into Arabic, the latter identifying attitudes, feelings and behaviors related to eating. Results: The Arabic translated DBS scale demonstrated high translation accuracy and content validity estimates. Cronbach's α and McDonald's ω reliability coefficients for the translated scale were approximately 0.91. Test-retest reliability was 0.96. The three-factor model showed an acceptable fit (CFI = 0.93, TLI = 0.92, RMSE = 0.08, SRMR = 0.06). The Arabic version of the DBS was found to have good convergent validity, as evidenced by the significant correlation between the EAT-26 and DBS questionnaires (r = 0.53, p < 0.01). Conclusion: The Arabic version of the DBS is highly reliable and has sufficient content validity to measure belief about personal ability to control one's weight.

A multicountry study on the psychometric properties of the Arabic version of the Sleep Preoccupation Scale (SPS) using both classical testing theory and item response theory.

BACKGROUND: Sleep distrurbances involves daytime preoccupation about sleep, which plays a critical role in perpetuating sleep disturbances. Recent cognitive models highlight the importance of daytime processes, like processing sleep-related information and interpretations during waking hours, in influencing sleep quality and quantity. The Sleep Preoccupation Scale (SPS) quantifies this daytime cognitive activity related to sleep. This study aimed to translate and validate an Arabic version of the SPS for assessing sleep preoccupation among Arabic speakers. METHODS: 523 Arabic speakers (mean age 23.6 years, 75% female) from four countries completed the Arabic SPS alongside the Athens Insomnia Scale, Generalized Anxiety Disorder-7 Scale, and the Anxiety and Preoccupation about Sleep Questionnaire (APSQ). The sample repeated the SPS after two weeks for test-retest reliability. Confirmatory factor analysis evaluated the SPS's two-factor structure. Internal consistency, item response theory, and convergent validity with the other scales were examined. RESULTS: Confirmatory factor analysis supported the two-factor model's fit. Measurement invariance results suggest that the SPS exhibits a similar basic factor structure across both insomnia and non-insomnia groups. The Arabic SPS demonstrated good internal consistency (Cronbach's α = 0.92, McDonald's ω = 0.92) and two-way mixed effects, consistency, single rater/measurement intraclass correlation coefficient (ICC) test-retest reliability (ICC = 0.95). Most items exhibited satisfactory item response theory fit statistics and discrimination. The SPS total score showed strong positive correlations with insomnia severity (r = 0.48, p < 0.001), generalized anxiety (r = 0.57, p < 0.001), and sleep-related anxiety/preoccupation (r = 0.79, p < 0.001), demonstrating convergent validity. CONCLUSION: The Arabic version of the SPS demonstrated good psychometric properties and validity, supporting its use for assessing sleep preoccupation among Arabic speakers. This culturally-adapted version enhances sleep assessment capabilities for improving insomnia understanding and treatment within Arabic-speaking populations.

Pre-Sleep Arousal Scale (PSAS): Translation and Evaluation of Its Psychometric Properties in an Arabic Version.

Purpose: The Pre-Sleep Arousal Scale (PSAS) is a well-recognized instrument utilized for measuring cognitive and somatic arousal before sleep. Although the PSAS is useful, an Arabic version of the scale has not yet been developed and validated. The current study aimed to translate the PSAS into Arabic language and evaluate its psychometric properties, such as reliability and validity, in an Arabic-speaking population. Patients and Methods: A cross-sectional survey was conducted with 438 participants who completed the Arabic version of the PSAS, along with other validated measures of insomnia, anxiety, and sleep effort. Results: The results indicated that the Arabic version of the PSAS maintained the original scale's two-factor structure. The factor loadings for PSAS-Cognitive ranged from 0.57 to 0.75, and for PSAS-Somatic, from 0.45 to 0.70, with all loadings being statistically significant (p < 0.001). The Arabic version of the PSAS exhibited high internal consistency (McDonald's ω = 0.86; Cronbach's α = 0.86; Guttman's λ2 = 0.86; Greatest Lower Bound = 0.90) and test-retest reliability (ICC = 0.88) over two weeks. The PSAS demonstrated good concurrent and convergent validity. We documented significant large differences between individuals with "no insomnia" and those with "insomnia" symptoms across cognitive, somatic, and total pre-sleep arousal (all p <0.001). The insomnia group consistently scored higher scores for PSAP and its subscales. Conclusion: These findings suggest that the Arabic version of the PSAS is a reliable and valid tool for assessing pre-sleep arousal in Arabic-speaking individuals.

A systematic review, meta-analysis, and meta-regression of the prevalence of self-reported disordered eating and associated factors among athletes worldwide.

BACKGROUND: The purpose of this meta-analysis was to provide a pooled prevalence estimate of self-reported disordered eating (SRDE) in athletes based on the available literature, and to identify risk factors for their occurrence. METHODS: Across ten academic databases, an electronic search was conducted from inception to 7th January 2024. The proportion of athletes scoring at or above predetermined cutoffs on validated self-reporting screening measures was used to identify disordered eating (DE). Subgroup analysis per country, per culture, and per research measure were also conducted. Age, body mass index (BMI), and sex were considered as associated/correlated factors. RESULTS: The mean prevalence of SRDE among 70,957 athletes in 177 studies (132 publications) was 19.23% (17.04%; 21.62%), I2 = 97.4%, τ2 = 0.8990, Cochran's Q p value = 0. Australia had the highest percentage of SRDE athletes with a mean of 57.1% (36.0%-75.8%), while Iceland had the lowest, with a mean of 4.9% (1.2%-17.7%). The SRDE prevalence in Eastern countries was higher than in Western countries with 29.1% versus 18.5%. Anaerobic sports had almost double the prevalence of SRDE 37.9% (27.0%-50.2%) compared to aerobic sports 19.6% (15.2%-25%). Gymnastics sports had the highest SRDE prevalence rate, with 41.5% (30.4%-53.6%) while outdoor sports showed the lowest at 15.4% (11.6%-20.2%). Among various tools used to assess SRDE, the three-factor eating questionnaire yielded the highest SRDE rate 73.0% (60.1%-82.8%). Meta-regression analyses showed that female sex, older age, and higher BMI (all p < 0.01) are associated with higher prevalence rates of SRDE. CONCLUSION: The outcome of this review suggests that factors specific to the sport affect eating behaviors throughout an athlete's life. As a result, one in five athletes run the risk of developing an eating disorder. Culture-specific and sport-specific diagnostic tools need to be developed and increased attention paid to nutritional deficiencies in athletes.

Disordered eating (DE) refers to eating behaviors that limit food choices, reduce or exaggerate food intake, cause physical discomfort, create a sense of loss of control, or lead to negative emotions like shame or guilt. The DE label does not signify the presence of a diagnosed mental health disorder, but, rather, describes self-reported, regular eating patterns that psychiatrists consider to fall into the at-risk category for an eating disorder. In this review, we performed a search of academic databases to find all relevant studies that measured the frequency of self-reported DE in athletes. We analyzed 177 studies involving over 70,000 athletes in total. In this study, DE was defined as a score above cut-off on validated screening tests for problematic eating behaviors. Our goal was to estimate the prevalence of DE in athletes globally and to determine the factors that increase risk. We found that approximately 1 in 5 athletes (19%) endorsed DE behaviors such as, among others, restrictive dieting, bingeing, and purging. These behaviors were seen most commonly in indoor sports like gymnastics and less commonly in the context of outdoor sports. Rates were highest in female athletes, older athletes, athletes with high body mass index (BMI) scores, and those from Eastern countries and cultures. Australia had the highest rates (over 50%), while rates were lowest in Iceland. We suggest the development of screening tests specifically tailored and applicable to athletes. In addition, we recommend raising public awareness of the health effects of nutrition in sports.

The Psychometric Properties of the Arabic Version of the Anxiety and Preoccupation About Sleep Questionnaire (APSQ).

Background: Insomnia disorder is a common health condition; it has a role in increasing the possibility of developing other psychological disorders, including anxiety and depression. Anxiety and preoccupation with sleep are two examples of common cognitive factors that contribute to the development of chronic insomnia; thus, it is important to have a tool that assesses worry in insomnia. There is no comprehensive psychiatric measure to assess anxiety and preoccupation with sleep in Arabic. We conducted this study to translate, adapt, and validate the Arabic version of the Anxiety and Preoccupation about Sleep Questionnaire (APSQ), providing a reliable psychometric tool to assess concerns regarding sleep within Arabic-speaking communities. Methods: The translation process of the scale involved several steps, including forward and backward translation. A cross-sectional study was conducted using an online survey completed by 523 participants from various Arabic-speaking countries. Psychometric analysis was performed utilizing the R software, including internal consistency, test-retest reliability, and confirmatory factor analysis. In addition, convergent and divergent against the Athens insomnia scale (AIS) and general anxiety disorder (GAD) were conducted. Results: The Arabic-translated form of the APSQ expresses excellent internal consistency with a value of 0.91 for both Cronbach's α and McDonald's ω. The test-retest reliability of a subsample showed an excellent coefficient of 0.93 (p<0.01). A good fit of the APSQ was observed by CFI = 0.93, TLI = 0.91, SRMR = 0.05, and RMSEA = 0.1. Convergent and divergent against AIS and GAD showed statistically significant correlations of 0.85 (p<0.01) and 0.69 (p<0.01), respectively. Our sample showed a mean APSQ score of 31.28 ± 8.31, and the mean age was 23.62 ± 7.5. Conclusion: The Arabic APSQ is reliable and valid for measuring anxiety and preoccupation with sleep in Arabic countries. Using translated APSQ for clinical diagnosis and research is currently trustworthy.

Reliability generalization meta-analysis of orthorexia nervosa using the ORTO-11/12/15/R scale in all populations and language versions.

BACKGROUND: The ORTO scale was developed in 2004 as a self-report questionnaire to assess symptoms of orthorexia nervosa (ON). ON is an unhealthy preoccupation with eating healthy food. The scale aims to measure obsessive attitudes and behaviors related to the selection, purchase, preparation, and consumption of pure, healthy food. Since its development, the ORTO-15 has been adapted into several shorter versions. The objective was to conduct a reliability generalization meta-analysis of the ORTO scale and its variant versions in all populations and languages. METHODS: A systematic literature search was conducted to identify studies reporting the internal consistency of ORTO. Random-effect models were used to evaluate summary statistics of reliability coefficients, weighting the coefficients by the inverse variance using the restricted maximum likelihood method. The heterogeneity among the reliability coefficients was evaluated and assessed using numerous statistical metrics. The tau (τ), tau2 (τ2), I2, H2, R2, df, and the Q-statistic are among those obtained. Meta-regression analyses were used to examine moderators such as age and sex. RESULTS: Twenty-one studies (k = 21) involving 11,167 participants (n = 11,167) were analyzed. The overall effect estimate on internal consistency was 0.59 (95% CI 0.49-0.68), with a minimum reliability coefficient of 0.23 and a maximum reliability coefficient of 0.83. The heterogeneity statistics were found to have an I2 of 99.31%, which suggested high heterogeneity owing to a decrease in the confidence interval (95% CI) and an increase in variability. Sensitivity analysis revealed that a few studies strongly influenced the overall estimate. Egger's test suggested possible publication bias. Neither age nor sex significantly moderated reliability via meta-regression. CONCLUSIONS: The ORTO scale has a relatively low pooled reliability coefficient. Alternative ON assessment tools with enhanced psychometric properties are needed. Clinicians should not base diagnoses or treatment decisions on ORTO alone. Comprehensive psychiatric assessment is essential for accurate ON evaluation.

This review looked at the reliability of the ORTO scale and its shortened versions for assessing orthorexia nervosa (an unhealthy obsession with eating healthy foods). The researchers analyzed data from 21 previous studies involving over 11,000 participants. Results showed that the ORTO scale had relatively low reliability in consistently measuring orthorexia symptoms across studies. The summary reliability score was 0.59 on a 0 to 1 scale, with individual study scores ranging from 0.23 to 0.83. There was a significant inconsistency across the different study results. We concluded that the ORTO scale has low reliability overall for diagnosing orthorexia nervosa. New assessment tools with better measurement properties are needed. Clinicians should not rely solely on the ORTO scale, but should conduct a comprehensive psychological evaluation to properly assess for orthorexia.

Translating and validating the Ghosting Questionnaire into Arabic: results from classical test theory and item response theory analyses : Short title: the arabic version of the Ghosting Questionnaire.

BACKGROUND: Ghosting refers to the sudden cessation of communication in interpersonal relationships. Ghosting has gained attention as a phenomenon commonly encountered in the context of digital communication. Earlier studies on ghosting mostly focused on Western societies while, in Arab societies, research into this practice has yet to be initiated. The current study aimed to address this gap by translating and validating the commonly used Ghosting Questionnaire (GHOST) into Arabic. METHODS: The translation process involved forward and back translation, expert review, and pilot testing to ensure linguistic and cultural equivalence. A convenience sample of 607 participants from Bahrain, Egypt, Jordan, Oman, and Tunisia completed the Arabic version of the GHOST. Statistical analyses, including reliability testing and confirmatory factor analysis, were conducted to assess the psychometric properties of the instrument. RESULTS: The Arabic version of the GHOST demonstrated high reliability. The Cronbach's alpha (α = 0.87) and McDonald's omega (ω = 0.87) coefficients indicated strong internal consistency. Test-retest reliability coefficients confirmed the stability of the responses over time (ICC 0.89, p < 0.001). CFA supported a single-factor structure in alignment with the conceptual framework of the original English version. CONCLUSIONS: The successful translation and validation of the GHOST into Arabic provide researchers with a reliable tool for investigating ghosting behavior within Arab societies. Future research endeavors can build upon these findings to explore the psychological implications of ghosting. Researchers can now also develop culturally sensitive understanding of online dating and related practices in Arab communities.

Adapting the athlete sleep behavior questionnaire (ASBQ) for Arabic-speaking populations: Translation, reliability testing, and validation using classical theory and item response theory.

Sleep is essential for athletes' physical performance as well as their general health, well-being, and quality of life. To assess athletes' sleep behaviors, the Athlete Sleep Behavior Questionnaire (ASBQ) was developed in the English language. However, a validated Arabic-version of the ASBQ is lacking. This study aimed to translate the ASBQ into Arabic (ASBQ-AR) and evaluate its reliability and validity among Arabic-speaking athletes. A total of 458 participants (254 athletes, 202 non-athletes) from four Arabic countries completed the ASBQ-AR and the Insomnia Severity Index (ISI) questionnaires. The psychometric properties of the ASBQ-AR were examined using unidimensional reliability analysis, confirmatory factor analysis (CFA), Item Response Theory (IRT), and convergent validity. The ASBQ-AR had acceptable internal consistency (Cronbach's α = 0.723, McDonald's ω = 0.725) and a factorial structure, confirming its construct validity. CFA demonstrated improved model fit indices after the removal of two potentially misfitting items (items 4 and 13); however, the model's fit to the data remains suboptimal. IRT results indicated that the majority of items demonstrated a good model fit, suggesting effective measurement of the intended construct without significant interference, except for ASBQ-AR 4. Additionally, ASBQ-AR 4 appears to present the highest level of difficulty for respondents. In terms of convergent validity, the mean ASBQ-AR global score was correlated with the mean ISI global score (r = 0.5, p < 0.0001). The ASBQ-AR is a reliable and valid tool for assessing maladaptive sleep practices among Arabic-speaking athletes. Additional refinements to the ASBQ-AR are warranted to optimize its psychometric properties.

Menstrual cycle symptoms are associated with nutrient intake: Results from network analysis from an online survey.

BACKGROUND: Less is understood about female's nutrient intake's impact on the severity of the menstrual cycle (MC) symptoms, which consequently interferes with their life quality. OBJECTIVES: The goal of this study is to look at the relationship between female nutrient consumption and the severity of MC symptoms to better understand how food affects women's quality of life during their MCs. DESIGN: To investigate this impact among healthy adult women, a self-administered, cross-sectional online questionnaire was obtained from 204 regularly menstruating women aged between 18 and 40. METHODS: The questionnaire included questions on sociodemographic characteristics, a semi-food frequency questionnaire (FFQ), Arabic Premenstrual Syndrome Scale (A-PMS-S) for MC symptoms. RESULTS: Results showed intake of polyunsaturated fatty acids (PUFAs) was associated with lower no to mild versus moderate to severe physical symptoms (odds ratio (OR): 0.71, 95% confidence interval (CI): 0.59-0.85; p < 0.001), psychological symptoms (OR: 0.87, 95% CI: 0.77-0.99; p < 0.05), and functioning symptoms (OR: 0.92, 95% CI: 0.83-1.02; p > 0.1). Thiamine prevented psychological symptoms (OR: 0.02, 95% CI: 0.02-0.02; p < 0.001), physiological symptoms (OR: 0.59, 95% CI: 0.58-0.60; p < 0.001), and functioning symptoms (OR: 0.47, 95% CI: 0.47-0.48; p < 0.001). Saturated fat, iron, and niacin intakes increased the risk of experiencing MC psychological symptoms. CONCLUSION: Our findings suggest that MC symptoms were correlated with some nutrient intake from food sources, which is considered an external controllable factor more than demographic characteristics. Therefore, women should be aware of the type of food consumed during their monthly MC phase.

The global prevalence of screen-based disordered eating and associated risk factors among high school students: systematic review, meta-analysis, and meta-regression.

OBJECTIVE: Estimate the prevalence, and associated risk factors, of high school students who are considered at risk for an eating disorder based on screening measures. METHODS: An electronic search of nine databases was completed from their inception until 1st September 2022. A random-effects meta-analysis was conducted, and confounder (moderator) analyses and meta-regressions examined whether the overall prevalence estimate for of screen-based disordered eating (SBDE) was moderated by student age, BMI, or gender, as well as culture and type of SBDE assessment. RESULTS: The mean estimate of the prevalence of SBDE among high school students (K = 42 (66 datapoints), N = 56282] in the sample of 25 countries was 13% ([95% CI] = 10.0-16.8%, I2 = 99.0%, Cochran's Q p = 0.001). This effect was not moderated by features of the samples such as gender, BMI, or age. Among cultures, non-Western countries had a higher prevalence of SBDE prevalence than Western countries, but the difference was not significant. There was considerable variability in the prevalence estimates as a function of the assessment measure, but no meaningful pattern emerged. CONCLUSION: The estimated figure of 1 in 8 high school students with SBDE-unmoderated by gender and BMI-stands out as a problem in need of attention from public health officials, psychologists, psychiatrists, pediatricians, parents, and educators. There is a great need for innovative, integrated policy and program development all along the spectrum of health promotion and universal, selective, and indicated prevention. Further research is also needed to validate and refine this estimate by (a) conducting basic research on the accuracy of eating disorder screening measurements in samples ages 14 through 17; (b) examining representative samples in more countries in general and Latin American countries in particular; (c) clarifying the relationships between SBDE and age throughout the different phases of late childhood, adolescence, and emerging adulthood; and (d) investigating whether there are meaningful forms of disordered eating and whether these are associated with variables such as gender, ethnicity, and BMI.

We searched nine databases to identify studies of high school students that yielded an estimate of disordered eating based on screening measures such as the Eating Attitudes Test. Forty-two 42 studies (N = 56282 students) from 25 countries met the selection criteria. A random effects meta-analysis indicated that across those countries the best estimate of the prevalence of screen-based disordered eating is 13%. This estimate was not significantly moderated by BMI, gender, age, and whether the country was Western or non-Western. There was considerable variability in the prevalence estimates as a function of the assessment measure, but no meaningful pattern emerged. The estimated figure of 1 in 8 high school students with disordered eating is a problem deserving of attention from public health officials, psychologists, psychiatrists, pediatricians, parents, educators, and leaders committed to prevention and early identification of eating disorders and referral for treatment. Further research in many more countries is also needed to validate this estimate and to explore its relationship with development throughout adolescence and with variables that can help us to refine prevention and effective early identification and treatment of eating disorders.

The Preventable Effect of Taekwondo Sport among Cadets and Junior' Bone Mineral Density: DEXA Assessment.

Athletes competing in Taekwondo (TKD), the weight-category sport, tend to rapidly lose weight to achieve the desired body weight for better competitive results. Little is known about the effect of rapid weight reduction on bone mass density (BMD), especially during childhood and adolescence. The current study aimed to investigate the impact of rapid weight loss on BMD among cadets and juniors TKD athletes. A descriptive case series study design was conducted and collected from 28 males and females aged 12-17 years old, with mean age 14.4 ± 1.7. Dual-energy X-ray absorptiometry (DEXA) was used for both BMD and body composition assessment, and laboratory tests were also performed for the total calcium (Ca), TSH, free T4 (FT4), and 25-OH-vitamin D. Results showed normal levels of Ca (82.1%), TSH (96.4%), and FT4 (96.4%), whilst 85.7% had vitamin D deficiency. DEXA results showed that within male athletes, juniors had a wider range of BMD than cadets, while within females, results did not vary, with no statistical difference between both males and females. Our results suggested that children and adolescents' BMD was positively related to TKD sport regardless of the abnormal weight loss strategies used, as evidenced by laboratory results. Children and adolescents should be conscious and practice TKD sport adopting healthy weight loss behaviors.

Development and validation of a questionnaire (GHOST) to assess sudden, unexplained communication exclusion or "ghosting".

The topic of "ghosting" as a method of terminating a relationship has been discussed in both popular media and academic circles. Although research on this issue is scarce, the concept has acquired popularity and gained scholarly attention. A reliable and valid measure of this phenomenon does not, however, exist. GHOST (The Ghosting Questionnaire) was designed and psychometrically tested to explore ghostee experiences. A total of 811 adults participated in an online survey to test this instrument. It was developed based on a thorough analysis of research on the topic of ghosting using a phenomenological qualitative method to identify ghosting domains and generate questionnaire items. In terms of content validity and construct validity, the final version of the measure was found to be satisfactory. GHOST was found to have adequate internal consistency - scores of 0.74, 0.74, and 0.80, indicating acceptable Cronbach's alpha, McDonald's omega, and ordinal's alpha coefficients, respectively. Factor analyses found the GHOST questionnaire to be a valid and reliable instrument that can be used for screening ghosting experiences and for designing community-based distress prevention and intervention programs. A dynamic fit index (DFI) cutoffs approach was also used and showed robust fitting.
