An assessment of the psychometric properties of the Coping Strategies Questionnaire - Sickle Cell Disease (CSQ-SCD) among adults in the United States.

BACKGROUND: Previous studies have reported conflicting factor structures of the Coping Strategies Questionnaire - Sickle Cell Disease (CSQ-SCD). This study examined the psychometric properties of the CSQ-SCD among adults with SCD in the United States. METHODS: This study implemented a cross-sectional study design with web-based self-administered surveys. Individuals with SCD were recruited via an online panel. Psychometric properties, including factorial and construct validity, and internal consistency reliability, of the CSQ-SCD were assessed. RESULTS: A total of 196 adults with SCD completed the survey. Confirmatory factor analysis (CFA), using maximum likelihood estimation and the 13 subscale scores as factor indicators, supported a three-factor model for the CSQ-SCD compared to a two-factor model. Model fit statistics for the three-factor model were: Chi-square [df] = 227.084 [62]; CFI = 0.817; TLI = 0.770; RMSEA [90% CI] = 0.117 [0.101-0.133]; SRMR = 0.096. All standardized factor loadings (except for the subscales isolation, resting, taking fluids, and praying and hoping) were > 0.5 and statistically significant, indicating evidence of convergent validity. Correlations between all subscales (except praying and hoping) were lower than hypothesized; however, model testing revealed that the three latent factors, active coping, affective coping, and passive adherence coping were not perfectly correlated, suggesting discriminant validity. Internal consistency reliabilities for the active coping factor (α = 0.803) and affective coping factor (α = 0.787) were satisfactory, however, reliability was inadequate for the passive adherence coping factor (α = 0.531). Given this overall pattern of results, a follow-up exploratory factor analysis (EFA) was also conducted. The new factor structure extracted by EFA supported a three-factor structure (based on the results of a parallel analysis), wherein the subscale of praying and hoping loaded on the active coping factor. CONCLUSIONS: Overall, the CSQ-SCD was found to have less than adequate psychometric validity in our sample of adults with SCD. These results provide clarification around the conflicting factor structure results reported in the literature and demonstrate a need for the future development of a SCD specific coping instrument.

Translation, adaptation, and psychometric properties of the Brazilian-Portuguese version of the Quality of Life in Children with Vernal Keratoconjunctivitis questionnaire.

PURPOSE: The prevalence of ocular allergy varies according to the population and location of the study. Severe forms of ocular allergy are associated with compromised quality of life. In this study, we aimed to evaluate the application of the Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire to children and adolescents with different subtypes of allergic conjunctivitis. METHOD: A total of 48 patients (aged 5-12 years) with allergic conjunctivitis were included in this study. They were enrolled and monitored at a specialized center. After the clinical appointment, the children responded to the questionnaire on two occasions at an interval of 30 days. Individual scores (ranging from 0 to 3) of the 16 items were added. RESULTS: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire demonstrated good translation, adaptation, and intellectual properties, with substantial internal consistency (Cronbach's α coefficient = 0.702). There was no significant difference between the responses of the two interviews, revealing good reproducibility. The moderate/severe forms of allergic conjunctivitis had significantly higher quality of life scores (indicating a poorer quality of life) than the mild forms. CONCLUSIONS: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis proved to be quick, reliable, and reproducible for assessing the quality of life in children with allergic conjunctivitis. However, its ability to detect changes resulting from symptom aggravation or treatment needs to be further evaluated.

Cross-cultural adaptation and psychometric evaluation of the social frailty scale in Iranian older adults.

BACKGROUND: Social frailty is a holistic concept encompassing various social determinants of health. Considering its importance and impact on health-related outcomes in older adults, the present study was conducted to cross-culturally adapt and psychometrically evaluate the Social Frailty Scale in Iranian older adults in 2023. METHODS: This was a methodological study. The translation and cross-cultural adaptation of the Social Frailty Scale 8-item (SFS-8) was conducted according to Wild's guideline. Content and face validity were assessed using qualitative and quantitative methods. Then, 250 older adults covered by comprehensive health centers were selected using multistage random sampling. Participants completed the demographic questionnaire, the Abbreviated Mental Test score, the SFS-8, and the Lubben Social Network Scale. Construct validity was assessed by principal component analysis (PCA) and known-group comparisons. The Mann‒Whitney U test was used to compare social frailty scores between the isolated and non-isolated older adults. Internal consistency, equivalence, and stability were assessed using the Kuder-Richardson method, the intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and the minimum detectable change (MDC). The ceiling and floor effects were also assessed. The data were analyzed using JASP 0.17.3. RESULTS: The ratio and index of content validity and the modified kappa coefficient of all the items were 1.00. The impact score of the items was greater than 4.6. PCA identified the scale as a single component by removing two questions that could explain 52.9% of the total variance in the scale score. The Persian version of the Social Frailty Scale could distinguish between isolated and non-isolated older adults (p < 0.001). The Kuder-Richardson coefficient, ICC, SEM, and MDC were 0.606, 0.904, 0.129, and 0.358, respectively. The relative frequencies of the minimum and maximum scores obtained from the scale were 34.8 and 1.2, respectively. CONCLUSIONS: The Persian version of the Social Frailty Scale (P-SFS) can be used as a valid and reliable scale to assess social frailty in Iranian older adults.

Psychometric properties of an Arabic translation of the meaning in life scale in a sample of young adults.

BACKGROUND: Young adults are in a constant phase of realizing their meaning in life while being in a constant pursuit of meaning. Meaning in life is a subjective, personal construct related to the perception of one's own life. Considering that there are no measures that study this construct within the Arab context, this study aimed to examine the psychometric properties of an Arabic translation of the Meaning in Life Questionnaire (MLQ) in the Lebanese context with a sample of young adults. METHODS: A sample of 684 Lebanese young adults was recruited for this study, having a mean age of 21.74 years, 65.6% of which were females. Through an online questionnaire, participants were requested to complete the Meaning in Life Questionnaire (MLQ), Depression, Anxiety and Stress Scale (DASS-8) and the Oviedo Grit Scale (EGO). RESULTS: CFA indicated that fit of the original bi-dimensional model of MLQ scores was inadequate. Items 9 and 10 cross-loaded to both MLQ factors. After removal of those 2 items, the final model displayed good fit indices. Reliability was good for the Search (ω = 0.89 / α = 0.89) and Presence (ω = 0.88 / α = 0.87) subscales. Additionally, across three levels of gender invariance (Configural, Metric and Scalar), no significant gender-based distinctions were observed in the MLQ scores. The Search subscale was significantly and positively associated with higher GRIT but not psychological distress, whereas the Presence subscale was significantly associated with higher GRIT and lower psychological distress. CONCLUSION: The results of this study contribute to the psychometric reliability and validity of the Arabic version of the MLQ and makes it available for dissemination among young adults within the Arab context. This allows for the implementation of new research that target construct of meaning in life, allowing for the accessibility of interventions that aim to foster the presence of and search for meaning in the lives of young adults within the Arab nations.

Validation of the arabic version of the EuroQol-5-dimension 5-level (EQ-5D-5 L) in patients with spinal degenerative diseases.

OBJECTIVE: This study aims to test the reliability and validity of the translated Arabic version of EQ-5D-5 L. METHODS: The study was conducted on 100 patients operated upon for degenerative spine diseases coming for follow up in the outpatient clinic of a Tertiary care hospital. Test-retest reliability was assessed by completing the self-administered tool in two follow up visits, one week apart, by 50 patients. Internal consistency was evaluated by Cronbach's alpha. Intra-class correlation coefficients and kappa statistics were performed to test for the agreement between the two ratings. Criterion validity was assessed by comparing the responses of 100 patients to the EQ-5D-5 L with scores of two validated questionnaires; the Arabic version of the Oswestry disability index and the Arabic version of short-form health survey-36. The construct validity was assessed using known-groups comparison to test for hypothesized differences concerning demographic and clinical variables. RESULTS: The Arabic version of EQ-5D-5 L questionnaire had a high reliability with high observed internal consistency (Cronbach's alpha = 0.816, CI: 0.719-0.886). It showed strong temporal stability, with ICCs of the EQ-5D-5 L score, index and EQ-visual analog scale (EQ-VAS) of 0.852, 0.801, and 0.839 respectively. Agreement by kappa was moderate; above 0.4, for all domains, except for the "Usual activities" domain. EQ-5D-5 L domains, VAS and index had moderate to strong significant correlations with SF-36 and ODI subscales and total scores in the correct direction indicating a good criterion validity of the instrument. CONCLUSION: The Arabic version of EQ-5D-5 L is reliable and valid for assessment of HRQoL of Arabic speaking patients.

Validity and Reliability Evidence and Norms for the Spanish Version of the Sexual Inhibition/Sexual Excitation Scales-Short Form.

BACKGROUND: The Sexual Inhibition/Sexual Excitation Scales-Short Form (SIS/SES-SF) is a brief instrument for assessing the propensity for sexual excitement and inhibition in men and women. The aim of the present study was to provide evidence for the validity and reliability of the Spanish version of the SIS/SES-SF scores by examining invariance, reliability (information function and internal consistency), the relationship between the scores and sexual functioning, and presenting its standard scores. METHOD: A total of 2,223 Spanish heterosexuals (43.41% men and 56.59% women) aged 18 to 83 years (M = 39.94, SD = 11.95), distributed across age groups (18-34, 35-49, ≥ 50 years old) participated. RESULTS: The three-factor structure of the Spanish version of SIS/SES-SF showed weak measurement invariance by sex and strict measurement invariance by age. The scores explained the dimensions of sexual functioning, especially sexual arousal and erection/lubrication. In addition, men and women without difficulties in sexual functioning demonstrated more propensity for sexual excitation and less sexual inhibition. The standard scores are presented by sex and age group. CONCLUSIONS: The study provides evidence of the validity and reliability of the SIS/SES-SF measures, confirming its usefulness for assessing propensity to sexual excitation and inhibition.

Spanish Adaptation of the Mentalization Questionnaire (MZQ) in Community Adolescents and Adults.

BACKGROUND: Despite the role of mentalization in mental health outcomes and prevention, psychometrically-evaluated screening measures for mentalization remain sparse. One widely-used mentalization questionnaire is the Mentalization Questionnaire (MZQ; Hausberg et al., 2012), which we aimed to adapt and validate for use in Spanish. METHOD: We adapted the MZQ to European Spanish and evaluated its psychometric properties in both adolescent ( = 389, ages 12-19, = 14.5) and adult community samples ( = 382, = 48). RESULTS: Confirmatory factor analysis resulted in a unidimensional structure including all items. This model had better goodness of fit than the original and other adaptations. Invariance analysis showed the same structure in adolescents compared by sex and age, and additionally in the adult versus adolescent samples. Evidence for convergent and discriminant validity was found. Internal consistency values in both adolescents and parents were fair and in the adolescent sample the MZQ scores remained moderately stable after re-test. CONCLUSIONS: The Spanish adaptation of the MZQ presents similar evidence of reliability and validity in the adolescent and adult samples. The results support this being a suitable version for evaluating mentalization in the general population.

Reliability and validity of rapid assessment tools for measuring 24-hour movement behaviours in children aged 0-5 years: the Movement Behaviour Questionnaire Baby (MBQ-B) and child (MBQ-C).

BACKGROUND: The development of validated "fit-for-purpose" rapid assessment tools to measure 24-hour movement behaviours in children aged 0-5 years is a research priority. This study evaluated the test-retest reliability and concurrent validity of the open-ended and closed-ended versions of the Movement Behaviour Questionnaire for baby (MBQ-B) and child (MBQ-C). METHODS: 300 parent-child dyads completed the 10-day study protocol (MBQ-B: N = 85; MBQ-C: N = 215). To assess validity, children wore an accelerometer on the non-dominant wrist (ActiGraph GT3X+) for 7 days and parents completed 2 × 24-hour time use diaries (TUDs) recording screen time and sleep on two separate days. For babies (i.e., not yet walking), parents completed 2 × 24-hour TUDs recording tummy time, active play, restrained time, screen time, and sleep on days 2 and 5 of the 7-day monitoring period. To assess test-retest reliability, parents were randomised to complete either the open- or closed-ended versions of the MBQ on day 7 and on day 10. Test-retest intraclass correlation coefficients (ICC's) were calculated using generalized linear mixed models and validity was assessed via Spearman correlations. RESULTS: Test-retest reliability for the MBQ-B was good to excellent with ICC's ranging from 0.80 to 0.94 and 0.71-0.93 for the open- and closed-ended versions, respectively. For both versions, significant positive correlations were observed between 24-hour diary and MBQ-B reported tummy time, active play, restrained time, screen time, and sleep (rho = 0.39-0.87). Test-retest reliability for the MBQ-C was moderate to excellent with ICC's ranging from 0.68 to 0.98 and 0.44-0.97 for the open- and closed-ended versions, respectively. For both the open- and closed-ended versions, significant positive correlations were observed between 24-hour diary and MBQ-C reported screen time and sleep (rho = 0.44-0.86); and between MBQ-C reported and device-measured time in total activity and energetic play (rho = 0.27-0.42). CONCLUSIONS: The MBQ-B and MBQ-C are valid and reliable rapid assessment tools for assessing 24-hour movement behaviours in infants, toddlers, and pre-schoolers. Both the open- and closed-ended versions of the MBQ are suitable for research conducted for policy and practice purposes, including the evaluation of scaled-up early obesity prevention programs.

Development of Flood Preparedness Behavior Scale: A Methodological Validity and Reliability Study.

BACKGROUND: Floods are the most frequent natural disasters with a significant share of their mortality. Preparedness is capable of decreasing the mortality of floods by at least 50%. This paper aims to present the psychometric properties of a scale developed to evaluate the behavior of preparedness to floods in Sudan and similar settings. METHODS: In this methodological scale development study, experts assessed the content validity of the items of the developed scale. Data were collected from key persons of 413 households living in neighborhoods affected by the 2018 floods in Kassala City in Sudan. A pre-tested questionnaire of sociodemographic data and the Flood Preparedness Behavior Scale (FPBS) were distributed to the participants' houses and recollected. Construct validity of the scale was checked using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency of the scale was checked using Cronbach's alpha. Test-retest reliability was assessed by Pearson's correlation coefficient. Item analyses and tests of significance of the difference in the mean scores of the highest and lowest score groups were carried out to ensure discriminatory power of the scale items. RESULTS: Experts agreed on the scale items. Construct validity of the scale was achieved using EFA by removing 34 items and retaining 25 items that were structured in three factors, named as: measures to be done before, during, and after a flood. Confirmatory factor analysis confirmed the construct obtained by EFA. The loadings of the items on their factors in both EFA and CFA were all > 0.3 with significant associations and acceptable fit indices obtained from CFA. The three factors were found to be reliable in terms of internal consistency (Cronbach's alpha coefficients for all factors were > 0.7) and test-retest reliability coefficient. In item analysis, the corrected total item correlations for all the items were > 0.3, and significant differences in the means of the highest and lowest score groups indicated good item discrimination power. CONCLUSION: The developed 25 items scale is an instrument which produces valid and reliable measures of preparedness behavior for floods in Sudan and similar settings.

Patient experiences in ulcerative colitis: conceptual model and review of patient-reported outcome measures.

PURPOSE: To identify symptoms and their impacts on daily functioning and health-related quality of life (HRQoL) experienced by adult patients with ulcerative colitis (UC) and evaluate patient-reported outcome (PRO) measures for UC clinical studies. METHODS: A conceptual model of symptoms and impacts of UC were developed from a literature review. PRO measures were identified from the literature, clinical trials databases, health technology assessment submissions, and regulatory label claims, and were selected for conceptual analysis based on disease specificity and use across information sources. PRO measures covering the most concepts when mapped against the conceptual model were assessed for gaps in psychometric properties using Food and Drug Administration (FDA) guidance and consensus-based standards for the selection of health measurement instruments (COSMIN) criteria. RESULTS: The conceptual model grouped the 52 symptom concepts and 72 proximal and distal impacts into eight, two, and five dimensions, respectively. Of 65 PRO measures identified, eight underwent conceptual analysis. Measures covering the most concepts and assessed for psychometric properties were the Inflammatory Bowel Disease Questionnaire, Symptoms and Impacts Questionnaire for UC, UC-PRO symptoms modules, UC-PRO impact modules, and Crohn's and UC Questionnaire; all had good or excellent support for content validity. The UC-PRO Signs and Symptoms fully met FDA guidance and COSMIN criteria for content validity and most psychometric properties. CONCLUSION: Existing PRO measures assess concepts relevant to patients with UC, but all PRO measures reviewed require further psychometric evaluation to demonstrate they are fit for purpose.

A Systematic Review of the Single-Item Burnout Question: Its Reliability Depends on Your Purpose.

BACKGROUND: Surveillance of burnout by the gold-standard Maslach Burnout Inventory (MBI) is hindered by cost and length. The validity and benchmarking of the commonly recommended and used single-item burnout question (SIBOQ) are unknown. We sought to (1) derive an equation for predicting the gold standard MBI from the SIBOQ and (2) measure the correlation of the SIBOQ with the full MBI and its subscales. METHODS: We sought studies in PubMed along with citations by and to included studies. We included studies that either correlated the SIBOQ and the MBI or reported the rates of burnout measured by both instruments. Two reviewers extracted data and CLARITY risk of bias. We used generalized linear mixed regression to separately quantify the predictive (benchmarking) and explanatory (hot-spotting) capabilities of the SIBOQ. We created a regression equation for converting SIBOQ scores to MBI scores. We meta-analyzed correlation coefficients (r) for the SIBOQ and MBI subscales. For all analyses, we considered an r of 0.7 as acceptable reliability for group-level comparisons. RESULTS: We included 17 studies reporting 6788 respondents. All studies had a high risk of bias, as no study had a response rate over 75% and no study was able to examine non-responders. The correlations (r) of the SIBOQ with the overall MBI were explanatory r = 0.82 and predictive r = 0.56. Regarding MBI subscales, the correlations of the SIBOQ with emotional exhaustion were adequate with r = 0.71 (95% CI 0.67-0.74; I2 = 89%), and depersonalization was r = 0.44 (95% CI 0.34-0.52; I2 = 90%). However, in 8 of 15 comparisons, the r was less than 0.70. DISCUSSION: The SIBOQ's usually adequate explanatory abilities allow "hot-spotting" to identify subgroups with high or low burnout within a single, homogenous survey fielding. However, the predictive ability of the SIBOQ indicates insufficient reliability in comparing local results to external benchmarks.

Measuring patient activation: the utility of the Patient Activation Measure administered in an interview setting.

BACKGROUND: Patient activation is an emerging field in healthcare research concerning knowledge, skills, and confidence of patients in managing their health. This is particularly important for patients with chronic diseases, who often require more complex care management and self-care skills. However, due to temporary or longer-lasting visual impairments, certain patient groups cannot answer a questionnaire independently. The main objective is to investigate the psychometric properties of the German Patient Activation Measure® (PAM) survey in an everyday clinical setting where it has to be read aloud. METHODS: Outpatients with macular edema participated in this questionnaire-based cross-sectional study. The study assessed patient activation by the PAM® survey, self-rated health, self-efficacy, quality of life, and general mood. Interviewers read questionnaires aloud to patients. Psychometric properties of the PAM® survey were investigated by item response theory (IRT), Cronbach's α and trait-trait correlations. RESULTS: The analysis included N = 554 patients. Median age was 69 (IQR 62.0-76.0) years and mean overall activation score 74.1 (SD 13.7). All items showed ceiling effects. Empirical reliability from the IRT model and Cronbach's α were 0.75. The PAM® survey showed a Spearman correlation of 0.54 with self-efficacy, 0.51 with quality of life and 0.34 with general mood. CONCLUSION: The read-aloud PAM® survey has been shown to provide to adequate measurement precision and convergent validity to be used as a screening tool in an everyday clinical setting. Objective assessment in an interview setting with the PAM® survey is possible. PAM® items are good in distinguishing lower to middle activated patients, but not patients with high activation. Further, issues with structural validity need more investigation.

Development and validation of an electronic version of Sydney Swallow Questionnaire.

BACKGROUND AND AIMS: Accurate assessment of patient-reported oropharyngeal dysphagia (OPD) is essential to guide appropriate management and evaluate response. The Sydney Swallow Questionnaire (SSQ) is a paper-based 17-item inventory developed and validated to objectively detect risk of OPD. An easy-to-use electronic version with digital output has significant potential in streamlining patient assessment. This study aims to develop and validate an electronic version of the SSQ (eSSQ) against the original paper version. METHOD: The English-based paper SSQ was adapted on the online REDcap (Research Electronic Data Capture) platform to be accessible on computer and mobile devices. Patients with OPD and asymptomatic controls completed both electronic and paper versions in randomized order. Patients with stable symptoms then repeated the eSSQ after ≥14 days for test-retest reliability. Paper-based and eSSQs were also collected from an independent cohort for external validation. Agreement of total scores between both versions and eSSQ test-retest reliability were calculated using two-way mixed-effects intra-class correlation coefficient (ICC). RESULTS: 47 dysphagic patients, 32 controls, and 31 patients from an external validation cohort were recruited. The most common underlying etiology was head and neck cancer. Mean eSSQ total score was 789 in dysphagic patients, and 68 in controls. eSSQ had excellent agreement with paper SSQ in total scores among all participants, with ICC 0.97 (95% CI [0.93, 0.98]) in controls, 0.97 (95% CI [0.94, 0.98]) in dysphagic patients and 0.96 (95% CI [0.92, 0.98]) in validation cohort. Test-retest reliability was also excellent (ICC 0.96, 95% CI [0.90, 0.98]). CONCLUSION: The newly developed eSSQ shows excellent agreement with the paper version and test-retest reliability. Future applications of its use may allow for more efficient and accessible patient assessment.

Cross-cultural validity and reliability of the comprehensive assessment of acceptance and commitment therapy processes (CompACT) in people with multiple sclerosis.

PURPOSE: The Comprehensive assessment of Acceptance and Commitment Therapy (CompACT) is a 23-item questionnaire measuring psychological flexibility, a quality of life protective factor. An 18-item version was recently produced. We assessed validity and reliability of CompACT, and equivalence of paper and electronic (eCompACT) versions in people with multiple sclerosis (PwMS) in Italy, Germany and Spain. METHODS: We used confirmatory factor analysis and assessed CompACT-23 and CompACT-18 measurement invariance between the three language versions. We assessed construct validity (Spearman's correlations) and internal consistency (Cronbach's alpha). Test-retest reliability (intraclass correlation coefficient, ICC) and equivalence of paper and eCompACT (ICC and linear regression model for repeated measures) were assessed in subsamples of PwMS. RESULTS: A total of 725 PwMS completed the study. The three-factor structure of the CompACT-23 showed poor fit (RMSEA 0.07; CFI 0.82; SRMR 0.08), while the fit of the CompACT-18 was good (RMSEA 0.05; CFI 0.93; SRMR 0.05). Configural and partial metric invariance were confirmed, as well as partial scalar invariance (reached when five items were allowed to vary freely). The CompACT-18 showed good internal consistency (all alpha ≥ 0.78); and test-retest reliability (all ICCs ≥ 0.86). Equivalence between paper and eCompACT was excellent (all ICCs ≥ 0.86), with no mode, order, or interaction effects. CONCLUSION: Results support using the refined CompACT-18 as a three-factor measure of psychological flexibility in PwMS. Paper and eCompACT-18 versions are equivalent. CompACT-18 can be used cross-culturally, but sub-optimal scalar invariance suggests that direct comparison between the three language versions should be interpreted with caution.

Construct Validity Testing of the Provider Co-Management Index to Measure Shared Care in Provider Dyads.

BACKGROUND: Co-management encompasses the dyadic process between two healthcare providers. The Provider Co-Management Index (PCMI) was initially developed as a 20-item instrument across three theory-informed subscales. OBJECTIVE: This study aimed to establish construct validity of the PCMI with a sample of primary care providers through exploratory and confirmatory factor analyses. METHODS: We conducted a cross-sectional survey of primary care physicians, nurse practitioners, and physician assistants randomly selected from the IQVIA database across New York State. Mail surveys were used to acquire a minimum of 300 responses for split sample factor analyses. The first subsample (derivation sample) was used to explore factorial structure by conducting an exploratory factor analysis. A second (validation) sample was used to confirm the emerged factorial structure using confirmatory factor analysis. We performed iterative analysis and calculated good fit indices to determine the best-fit model. RESULTS: There were 333 responses included in the analysis. Cronbach's alpha was high for a three-item per dimension scale within a one-factor model. The instrument was named PCMI-9 to indicate the shorter version length. DISCUSSION: This study established the construct validity of an instrument that scales the co-management of patients by two providers. The final instrument includes nine items on a single factor using a 4-point, Likert-type scale. Additional research is needed to establish discriminant validity.

Somatic Symptom Disorder-B criteria scale (SSD-12): Psychometric properties of the French version and associations with health outcomes in a population-based cross-sectional study.

OBJECTIVE: The 12-item Somatic Symptom Disorder-B Criteria Scale (SSD-12) is a self-reported questionnaire designed to assess the B criteria of the DSM-5 somatic symptom disorder. In this cross-sectional study, we aimed to examine the psychometric properties of the SSD-12 French version and associated health outcomes. METHODS: Participants were volunteers from the population-based CONSTANCES cohort who reported at least one new symptom that occurred between March 2020 and January 2021. Depressive symptoms were measured with the Center for Epidemiologic Studies-Depression scale (CES-D). RESULTS: A total of 18,796 participants completed the SSD-12. The scree plot was consistent with a 1-factor structure, while goodness-of-fit indices of the confirmatory factorial analyses and clinical interpretability were consistent with a 3-factor structure (excluding the item 7): 'Perceived severity', 'Perceived impairment', 'Negative expectations'. The Cronbach's α coefficients of the total and factors scores were 0.90, 0.88, 0.84 and 0.877, respectively. The total score was associated with depressive symptoms (Spearmann's rho: 0.32), self-rated health (-0.46), the number of persistent symptoms (0.32), and seeking medical consultation (odds ratio [95% confidence interval] for one interquartile range increase: 1.51 [1.48-1.54]). Among participants seeking medical consultation, those with higher SSD-12 scores were more likely to have their symptoms attributed to "stress/anxiety/depression" (1.32 [1.22-1.43]) and "psychosomatic origin" (1.25 [1.20-1.29]), and less to "COVID-19" (0.89 [0.85-0.93]). CONCLUSION: While the SSD-12 French version can be used as a unidimensional tool, it also has a 3-factor structure, somewhat different from the DSM-5 theoretical structure, with high internal consistency and clinically meaningful associations with other health outcomes.

Introducción:Las heridas de difícil cicatrización constituyen un problema de salud por su alta prevalencia y etiologías multifactoriales. El tratamiento comienza con la prescripción del agente terapéutico adecuado, seguido por el uso de instrumentos que permiten al profesional documentar la evaluación de la herida. Objetivo: El estudio pretende evaluar la fiabilidad y validez de la versión brasileña del instrumento RESVECH 2.0 en el contexto de heridas de difícil cicatrización. Método: Se realizó un estudio metodológico. Inicialmente, se aplicó una entrevista a los participantes para establecer un perfil; a continuación, se realizaron las evaluaciones de las heridas de difícil cicatrización de cualquier etiología (n = 179) con los instrumentos RESVECH 2.0 y Pressure Ulcer Scale for Healing 3.0 (PUSH 3.0). Resultados: Las propiedades psicométricas evaluadas fueron la validez de constructo convergente, la fiabilidad interobservador y la consistencia interna. La fiabilidad de la consistencia interna presentó los valores de 0,561 y 0,535. La fiabilidad interobservador presentó un valor Kappa que osciló entre 0,14 y 0,76 y un coeficiente de correlación intraclase (CCI) de 0,87. Para la validez de constructo convergente, se aplicó el coeficiente de correlación de Spearman a los datos de las puntuaciones de los instrumentos RESVECH 2.0 y PUSH 3.0 (n = 150); el coeficiente obtenido fue de 0,717. Conclusión: Se concluye que el instrumento mostró indicios de fiabilidad y validez.

Psychometric properties of the Romanian version of the female sexual function index (FSFI-RO).

BACKGROUND: Female sexual dysfunction (FSD) is a highly prevalent health disorder and no self-report questionnaire on female sexual function is available in Romanian. Therefore we considered the Female Sexual Function Index (FSFI) to be the most appropriate due to its excellent psychometric properties. The FSFI is a measuring scale with 19 items that assess the six domains of female sexual function: desire, arousal, lubrication, orgasm, satisfaction and pain. The paper aims to analyze the psychometric reliability and validity of the FSFI-RO (Romanian Version of the Female Sexual Function Index). METHODS: 385 women (aged 18 to 51) enrolled in the present study. To assess the presence of FSD we used the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) criteria for sexual dysfunction. Then we categorized the participants into two groups: the FSD group (41%) and the healthy control group (59%). Women were then asked to fill out a form that included sociodemographic information and the FSFI-RO questionnaire. A sample of 50 women agreed to re-answer FSFI-RO in a 4-week interval in order to evaluate the test-retest validity of the questionnaire. The data were summarized using descriptive statistics: the test-retest reliability was measured by the intraclass correlation coefficient (ICC); Cronbach's alpha was employed to evaluate the internal consistency of the Romanian version of the FSFI, and validity was assessed by the content and construct validity. RESULTS: The results showed high test-retest reliability, with ICC from 0.942 to 0.991 in the domains and 0.987 in the total score. Regarding the internal consistency of the FSFI-RO, Cronbach's α coefficients were found to be high (α = 0.944). Convergent construct validity proved to be moderate to high in desire, arousal, lubrication, orgasm and, satisfaction domains, and weak correlation in the pain domain. Regarding the discriminant construct validity, the scores for each domain and the total score showed statistically significant differences between the FSD group and the control group. CONCLUSIONS: The FSFI-RO showed similar psychometric properties to those of the original version, therefore being a reliable and valid instrument that can be used in Romanian-speaking women.

Evaluation of psychometric properties of the eating restriction questionnaire and food involvement inventory in Iranian adults.

The objectives of this study were to translate and validate the Persian version of the food involvement inventory (FII) and eating restriction questionnaire (ERQ) and to determine the measurement invariance based on gender, body mass index (BMI) status, and age. This cross-sectional study included 1100 Iranian adults. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the construct validity of FII and ERQ. Convergent and discriminant validity, measurement invariance in gender, BMI and age, reliability including internal consistency, and stability were investigated for FII and ERQ. The results showed that the four-factor construct of the FII and the one-factor construct of the ERQ were 44.27% and 55.12% of the total variance, respectively. The factor loadings of all items were > .3 in both scales and none of the items were deleted. Fitting indices indicated that the four-factor construct of the FII and the one-factor construct of the ERQ had a good and acceptable fit among the Iranian adults. The Persian versions of the FII and ERQ, translated into Persian and localized according to international standards, had high construct, convergent and discriminant validity as well as high reliability.
