Dysphagia, health-related quality of life, and return to work after occipitocervical fixation.

PURPOSE: The purpose of this study was to evaluate patient-reported outcome measures (PROMS) on dysphagia, health-related quality of life (HRQoL) and return to work after occipitocervical fixation (OCF). Postoperative radiographic measurements were evaluated to identify possible predictors of dysphagia. METHODS: All individuals (≥ 18 years) who underwent an OCF at the study center or were registered in the Swedish spine registry (Swespine) between 2005 and 2019, and were still alive when the study was conducted, were eligible for inclusion. There was no overlap between the cohorts. Prospectively collected data on dysphagia (Dysphagia Short Questionnaire DSQ), HRQoL (EQ5D-3L) and return to work were used. Radiological and baseline patient data were retrospectively collected. In addition, HRQoL data of a matched sample of individuals was elicited from the Stockholm Public Health Survey 2006. RESULTS: In total, 54 individuals were included. At long-term follow-up, 26 individuals (51%) had no dysphagia, and 25 (49%) reported some degree of dysphagia: 11 (22%) had mild dysphagia, and 14 (27%) had moderate to severe dysphagia. On a group level, the OCF sample scored significantly lower EQVAS and EQ-5Dindex values compared to the general population (60.0 vs. 80.0, p = 0.016; 0.43 vs. 0.80, p < 0.001). Individuals working preoperatively returned to work after surgery. Of those responding, 88% stated that they would undergo the OCF operation if it was offered today. No predictors of dysphagia based on radiographic measurements were identified. CONCLUSION: Occipitocervical fixation results in a high frequency of long-term dysphagia. The HRQoL of OCF patients is significantly reduced compared to matched controls. However, most patients are satisfied with their surgery. No radiographic predictors of long-term dysphagia could be identified. Future prospective and systematic studies with larger samples and more objective outcome measures are needed to elucidate the causes of dysphagia in OCF.

Lifestyle patterns and incident type 2 diabetes in the Dutch lifelines cohort study.

We aimed to identify the underlying subgroups of the population characterized by distinct lifestyle patterns, and to investigate the associations between lifestyle patterns and risk of incident type 2 diabetes. Using data from the Dutch Lifelines cohort study, latent class analysis was performed to derive lifestyle patterns on five lifestyle factors, i.e., smoking, diet quality, TV watching time, physical activity level, and risk drinking. Associations between lifestyle patterns and incident type 2 diabetes were estimated. Among 61,869 participants analyzed, we identified 900 cases of type 2 diabetes during follow-up (205,696 person-years; incidence rate 4.38 per 1000 person-years). Five lifestyle pattern groups were identified. Using the "healthy lifestyle group" as reference, the "unhealthy lifestyle group" had the highest risk for type 2 diabetes (HR 1.51 [95%CI 1.24, 1.85]), followed by the "poor diet and low physical activity group" (HR 1.26 [95%CI 1.03, 1.55]). The "risk drinker group" and the "couch potato group" (characterized by excessive TV watching) showed no significantly elevated risk. These models were adjusted for age, sex, total energy intake, education, BMI, family history of diabetes, and blood glucose level at baseline. Our study shows that lifestyle factors tended to cluster in unique behavioral patterns within the heterogeneous population. These lifestyle patterns were differentially associated with incident type 2 diabetes. Our findings support the relevance of considering lifestyle patterns in type 2 diabetes prevention. Tailored prevention strategies that target multiple lifestyle risk factors for different lifestyle pattern groups may optimize the effectiveness of diabetes prevention at the population level.

Development and Validation of a Short Questionnaire Assessing the Behavior of Local Food Procurement in Quebec, Canada.

Background: Very few validated instruments, particularly screening tools applicable to large-cohort studies, are available to assess the behavior of local food procurement. Objective: The aim was to develop and validate a short questionnaire that measures local food procurement in a sample of French-speaking adults from Quebec, Canada, and to assess the association between local food-procurement behavior and diet quality. Methods: A comprehensive questionnaire developed previously to measure local food procurement [Locavore-Index (Locavore-I)] was simplified through a series of steps that included face-validity, exploratory factor analysis, and reliability testing (internal consistency). Construct validity of the resulting short Locavore-I Short Form (Locavore-I-SF) was examined in a sample of 299 adults (85% women) from the Quebec City metropolitan community. Results: The Locavore-I-SF comprises 12 questions that measure the frequency of short food supply chain use (self-production, farmers' markets, and community-supported agriculture box scheme) for 3 locally produced foods (carrot, tomato, and lettuce) as well as the geographical origin of those 3 foods. The Locavore-I-SF, which is scored on a 12-point scale, had a high internal consistency (Cronbach ɑ: 0.74). The Locavore-I-SF scores were strongly correlated with the reference scores obtained from the Locavore-I from which it was developed (r = 0.84, P < 0.0001). Locavore-I-SF scores also correlated (r = 0.50, P < 0.0001) with the geographical origin of foods measured by pictures of food labels taken by participants. Higher Locavore-I-SF scores were associated with behaviors consistent with eating local foods, such as gardening (vs. not gardening; mean ± SEM difference: 2.3 ± 0.4 points; P < 0.0001) and not being preoccupied by the foods' appearance standards (vs. being preoccupied; 1.4 ± 0.4 points; P = 0.0002). Finally, the Locavore-I-SF scores were weakly associated with the Healthy Eating Food Index-2019 score (B = 0.05 ± 0.02; P = 0.02). Conclusions: The Locavore-I-SF, a short questionnaire based on 3 locally produced foods in Quebec, measures the behavior of local food procurement with good reliability and acceptable validity metrics.

Psychometric standards of the test: internal consistency: Cronbach's α for EII-Control 0.83 with strong correlation between EII-Control-8 and EII-Control-EVA (r=0.5); reproducibility: intra-class correlation 0.70 for EII-Control; construct validity: moderate to strong correlations between IBD-Control, IBD-Control-8 and IBD-Control-VAS versus comparators; discriminant validity: P<.001; sensitivity to change: same response as quality of life index. Sensitivity and specificity at cut-off point 14 of 0.696 and 0.903, respectively, to determine quiescent status. Conclusions: The IBD-Control is a valid instrument to measure IBD-Control from the patient's perspective in our environment and culture. Its simplicity makes it a useful tool to support care.(AU)

A high-fibre personalised dietary advice given via a web tool reduces constipation complaints in adults.

Constipation can greatly impact the quality of life (QoL), which can be relieved by dietary fibres; however, preserving a higher fibre intake remains a challenge. We investigated the effects of a personalised dietary advice (PDA) on fibre intake and mild constipation complaints. A total number of twenty-five adults with mild constipation complaints were included in a 4-week observation period followed by a 4-week personalised intervention. The PDA provided high-fibre alternatives via a web tool. In weeks 1, 4 and 8, dietary intake, constipation complaints and QoL were assessed. Furthermore, participants collected a faecal sample at weeks 1, 4 and 8 to determine microbiota diversity and composition, and short-chain fatty acids (SCFA). Participants completed questions daily for 8 weeks regarding abdominal complaints, stool frequency and stool consistency. Fibre intake in week 8 was significantly higher compared to week 1 (Δ = 5·7 ± 6·7 g, P < 0·001) and week 4 (Δ = 5·2 ± 6·4 g, P < 0·001). Constipation severity and QoL significantly improved at week 8 compared to the observation period (P < 0·001). A higher fibre intake significantly reduced constipation severity (ß = -0·031 (-0·05; -0·01), P = 0·001) and the QoL (ß = -0·022 (-0·04; -0·01), P = 0·009). Stool consistency (P = 0·040) and abdominal pain (P = 0·030) improved significantly during the intervention period (P = 0·040), but stool frequency did not. Average microbial alpha diversity and composition and SCFA concentrations did not change over time, but indicated individual-specific dynamics. Several SCFAs were associated with constipation complaints. To conclude, a PDA effectively increased fibre intake and subsequently reduced constipation complaints, indicating that guided dietary adjustments are important and feasible in the treatment of mild constipation complaints.

Development and Validation of a Short Questionnaire on Dietary and Physical Activity Habits for Patients Submitted to Bariatric Endoscopic Therapies.

PURPOSE: Individuals with obesity frequently regain weigh after endoscopic bariatric therapies (EBT) unless they adhere to healthy habits. The objective was to create and validate a short, self-administered questionnaire (EMOVE) to assess healthy dietary and physical activity (PA) habits' adherence to be used in clinical practice. MATERIALS AND METHODS: In this prospective, unicentric study, 463 patients completed the short, Spanish EMOVE questionnaire, to be validated following the Medical Outcome Trust Criteria. Conceptual and measurement model, reliability (internal consistency and test-retest [subgroup of 93 patients]), construct validity, responsiveness, interpretability, and burden were evaluated. Patients enrolled from January 2017 through August 2018 and auto-filled the EMOVE at baseline and at 3, 6, and 12 months. RESULTS: Patients submitted to intragastric ballon for 6 and 12 months or POSE were 82.7% women with a mean age of 42.7 years, and a mean BMI of 37.1 kg/m2. Four factors were extracted with exploratory factor analysis related to intake frequency, portions and proportions, time and place of eating, and physical activity. EMOVE showed adequate internal consistency (α = 0.73), very good test-retest (r = 0.91, CI: 0.86-0.94; p < 0.001), moderate construct validity of dietary (r = 0.24, CI: 0.11-0.37, p < 0.001), and PA habits (r = 0.44, CI 0.30-0.58; p < 0.001). Stable responsiveness, with correlations from 0.29 to 0.39 (p < 0.001) between the EMOVE scores and the % of total weight loss at 3, 6, and 12 months. Participants categorized as having good or excellent habits (score ≥ 30 points) lost significantly more weight (p < 0.05). Finally, the administration burden was 2.96 min. CONCLUSION: The EMOVE is a useful tool in Spanish language to easily assess the level of adherence to healthy dietary and PA habits to be used routinely in clinical practice.

Is the modified household food security survey (HFSS) questionnaire a practical tool for screening food insecurity? Evidence from northwest of Iran.

BACKGROUND: Adequate supplies of food and food security (FS) are the fundamental aspects of human societies, and considered one of the pivotal factors of individual and social health. The aim of the present study was to assess the applicability of the short questionnaire for screening food insecurity (FI) and to evaluate the prevalence of FI in northwest of Iran. METHODS: In this study, 550 subjects aged ≥16 years were studied. Three-day dietary records and a short questionnaire were applied to estimate the prevalence of FI in terms of hunger and hidden hunger. The sensitivity, specificity and accuracy of the short questionnaire were assessed. Moreover, the association between the results of the short questionnaire and the criteria that were theoretically related to FI were examined. Data were presented as mean (SD), median (min-max) for the numeric normal and non-normal variables, respectively, and frequency (percent) for categorical variables. The between-group comparisons of variables were done using independent samples t test. P values less than 0.05 were considered statistically significant. RESULTS: The prevalence of hunger and hidden hunger was 30.8 and 46.0%, respectively. Overall, 23.2% of the subjects were classified as "food secure". The sensitivity, specificity and accuracy of the short questionnaire in determining hunger were 92.8% (95% CI: 87.3-95.9), 84.2% (95% CI: 79.3-89.3), and 87% (95% CI: 84-90.2), respectively. These values for hidden hunger were 21.6% (95% CI: 15.7-29.9), 92.3% (95% CI: 88.7-99.4), and 53.4% (95% CI: 47.9-59.8), respectively. Our study showed a statistically significant association between FI and socio-economic status. FI significantly enhanced the risk of underweight, while it markedly reduced the risk of overweight and obesity. The average frequency of monthly consumption of meat, dairy products, fruits, vegetables, and rice was significantly lower in food insecure group, while the median frequency of bread consumption was markedly higher in food insecure group. The participants of insecure group were less likely to consume fruits, vegetables, dairy products, rice and meat. CONCLUSIONS: FI was frequent in North-west of Iran. The findings indicated that the short questionnaire was a simple, low-cost and practical tool for screening FI in terms of hunger. TRIAL REGISTRATION: IR.TBZMED.REC.1397.400.

Psychometric Evaluation of the German Version of the Dietary Fat and Free Sugar-Short Questionnaire.

BACKGROUND: The Dietary Fat and Free Sugar-Short Questionnaire (DFS) is a cost- and time-efficient self-report screening instrument to estimate dietary intake of saturated fat and free sugar. To date, only the English version has been psychometrically evaluated. We assessed the psychometric characteristics of the German version of the DFS in individuals with normal weight, overweight, and obesity. METHOD: Sixty-five adult participants completed a German translation of the DFS and a validated food frequency questionnaire (FFQ). We correlated participants' percentage of energy intake from saturated fat and free sugar from the FFQ with the DFS scores. To establish test-retest reliability, participants completed the DFS a second time. To investigate convergent validity, we correlated participants' DFS scores with self-reported eating behavior and sensitivity to reward. RESULTS: DFS scores correlated with percentage of energy from free sugar (rs = 0.443) and saturated fatty acids (rs =0.258) but not with non-target nutrients. The correlation between DFS scores and percentage energy from free sugar was not moderated by body mass index (BMI), whereas the correlation with percentage energy from saturated fat slightly decreased with BMI. Intra-class correlation as an indicator of test-retest reliability was 0.801. DFS scores correlated significantly with restraint of eating behavior (rs = -0.380) and feelings of hunger (rs = 0.275). Correlations of the DFS score with disinhibited eating and sensitivity to rewards failed to be significant. CONCLUSION: Our data indicate that the German version of the DFS might be a psychometrically sound self-report instrument to estimate saturated fat and free sugar intake of German adults.

The association between the Mediterranean diet and high physical activity among the working population in Croatia.

BACKGROUND: Unhealthy eating habits and physical inactivity constitute an emerging public health problem. The working population is of special interest for public health monitoring and evaluation because workers' unhealthy lifestyles may lead to reduced work ability. The aim of this study was to determine diet quality and adherence to the Mediterranean diet (MD), according to the level of physical activity, and to detect variables associated with the working population's being highly physically active. MATERIAL AND METHODS: At the Institute for Occupational Medicine 400 full-time workers were examined for obesity factors, filled in the short version of International Physical Activity Questionnaire (IPAQ-short) and a validated food frequency questionnaire for adherence to the Mediterranean diet using Mediterranean Diet Score (MDS). The workers were divided into low, moderate and high physical activity groups according to the IPAQ-short scoring protocol. Hierarchical linear regression was performed to determine the variables associated with being highly active. RESULTS: One-third of the participants were highly physically active and their diet adhered to the MD (MeMDS = 7). Significant variables associated with a high level of physical activity were gender (p < 0.001), age (p = 0.02), waist-to-hip ratio (WHR) (p < 0.001), sitting level (p = 0.044) and occupational type (p < 0.001). CONCLUSIONS: It was found that the participants displaying a high level of physical activity had a better quality diet that adhered to the Mediterranean diet but not to a significant degree. The variables associated with a high level of physical activity were male gender, younger age, normal WHR, non-sedentary occupation and reduced sitting time. The study findings could serve the purpose of improving future public health promotion of physical activity and the Mediterranean diet. Med Pr. 2019;70(2):169-76.

Artificial disc replacement versus fusion in patients with cervical degenerative disc disease and radiculopathy: a randomized controlled trial with 5-year outcomes.

In BriefIn this study the authors compare cervical arthroplasty with fusion surgery in a randomized controlled trial using patient-reported outcome measures and MRI after 5 years of follow-up. Because the main purpose of arthroplasties is to prevent adjacent-segment pathology, it is important to investigate if that is actually realized in practice.

Proposition for a shortened version of the Leeds Food Preference Questionnaire (LFPQ).

The Leeds Food Preference Questionnaire (LFPQ) assesses, among other components, food preference (FP) using a procedure that requires both time and concentration. Its use may therefore be difficult in a complex protocol. In this article, we assessed the suitability of two shorter versions: 1) the LFPQ-S2, using two instead of four foods per group, and 2) the food preference questionnaire (FPQ-S16), using the 16 same foods as the LFPQ, displayed simultaneously, that have to be ranked in order of preference. We assessed the reliability of these short versions using correlations and interchangeability (Bland and Altman) analyses. Sixty-nine healthy French adults completed the original LFPQ using foods adapted to the French context, and then the FPQ-S16 procedure before (hungry state) and after (satiated state) a classic lunch. Finally, they had to select the two foods that best depict the characteristics of each group. The two foods receiving the most votes were used to calculate FP scores with the LFPQ-S2 procedure. The FP scores were no different between the three questionnaires and were modified similarly by lunch intake. The FP scores also highly correlated between the two short versions and the LFPQ (mean r = 0.83 and 0.88 in the hungry state and r = 0.86 and 0.87 in the satiated state for LFPQ-S2 and FPQ-S16, respectively). Finally, the FPQ-S16 was considered to be a better surrogate of the LFPQ than the LFPQ-S2. Scores of specific categories (groups of foods categorized by one property; e.g. high-fat foods) showed modest-to-good agreement, whereas scores of combined categories (groups of foods categorized by combined properties, e.g. high-fat and sweet foods) showed poor-to-modest agreement. Overall, the two short versions of the LFPQ could replace it to assess FP in a protocol in which time is limited. The FPQ-S16 appears to be a better solution than the LFPQ-S2, based on interchangeability analyses.

Measuring limitations in activities of daily living: a population-based validation of a short questionnaire.

PURPOSE: A newly developed questionnaire assessing limitations in activity of daily living (LADL-Q) that should improve assessment of LADL is tested in a large population-based validation study. METHODS: This survey was paper-based. Overall, 16,634 individuals who were representative of the working population in the German-speaking part of Switzerland participated in the study. Item analysis was used the final version of the LADL-Q to four items per subscale that correspond to potential problems in three body regions (back and neck, upper extremities, lower extremities). Analysis included tests for reliability, internal consistency, dimensionality and convergent validity. RESULTS: Test-retest reliability coefficients after 2 weeks ranged from 0.82 to 0.99 (Mdn = 0.87), with no item having a coefficient below 0.60. The median item-total coefficients ranged between moderate and good. Correlation coefficients between LADL-Q subscales and three validated clinical instruments (Western Ontario and McMaster Universities osteoarthritis index, shoulder pain disability index, Oswestry) ranged from 0.63 to 0.81. In structural equation modeling the three subscales were significantly related with two important outcomes in occupational rehabilitation: self-reported general health and daily task performance. CONCLUSION: The new LADL-Q is a brief, reliable and valid tool for assessment of LADL in studies on musculoskeletal health.

Validation of two short questionnaires assessing physical activity in colorectal cancer patients.

BACKGROUND: In order to investigate the impact of adherence to recommendations of physical activity and sedentary time on health outcomes in clinical trials, there is a need for feasible tools such as questionnaires that can give representative estimates of these measures. The primary aim of the present study was to validate two such questionnaires and their ability to estimate adherence to the recommendations of physical activity defined as moderate-to- vigorous physical activity or moderate physical activity of at least 150 min/week in colorectal cancer patients. Secondarily, self-reported sedentary time from the HUNT-PAQ was also evaluated. METHODS: Participants from 'The Norwegian dietary guidelines and colorectal cancer survival-study' (CRC-NORDIET study) completed two short questionnaires; the NORDIET-FFQ (n = 78) and the HUNT-PAQ (n = 77). The physical activity monitor SenseWear Armband Mini was used as the reference method during seven consecutive days. RESULTS: The NORDIET-FFQ provided better estimates of time in moderate-to- vigorous physical activity and moderate physical activity than the HUNT-PAQ. The NORDIET-FFQ was unable to rank individual time in moderate-to- vigorous physical activity and moderate physical activity (Spearman's rho = 0.08, p = 0.509 and Spearman's rho rho = 0.01, p = 0.402, respectively). All intensities were under-reported by the HUNT-PAQ, but ranking of individual time in moderate physical activity and sedentary time were acceptable among women only (Spearman's rho = 0.37, p = 0.027 and Spearman's rho = 0.36, p = 0.035, respectively). The HUNT-PAQ correctly classified 71% of those not meeting the recommendations (sensitivity), and the NORDIET-FFQ correctly classified 63% of those who met the recommendations (specificity). About 67% and 33% reported to meet the recommendation of moderate-to- vigorous physical activity with the NORDIET-FFQ and HUNT-PAQ, respectively, whereas 55% actually met the moderate-to- vigorous physical activity according to the SenseWear Armband Mini. CONCLUSIONS: The NORDIET-FFQ provided better specificity and better estimates of PA than the HUNT-PAQ. The HUNT-PAQ provided better sensitivity, and provided better ranking of PA and sedentary time among women than NORDIET-FFQ. It is important to be aware of the limitations documented in the present study. TRIAL REGISTRATION: The study is registered on the National Institutes of Health Clinical Trials (Identifier: NCT01570010). Registered 4 April 2012.

Towards a short questionnaire for stepwise assessment of upper limb function, pain and stiffness in Duchenne muscular dystrophy.

PURPOSE: Duchenne muscular dystrophy can lead to upper extremity limitations, pain and stiffness. In a previous study, these domains have been investigated using extensive questionnaires, which are too time-consuming for clinical practice. This study aimed at gaining insight into the underlying dimensions of these questionnaires, and to construct a short questionnaire that can be used for clinical assessment. METHODS: Exploratory factor analysis was performed on the responses of 213 participants to a web-based survey to find the underlying dimensions in the Capabilities of Upper Extremity questionnaire, the ABILHAND questionnaire, and questionnaires regarding pain and stiffness. Based on these underlying dimensions, a stepwise approach was formulated. In addition, construct validity of the factors was investigated. RESULTS: In total, 14 factors were identified. All had high internal consistency (Cronbach's alpha >0.89) and explained 80-88% of the variance of the original questionnaires. Construct validity was supported, because participants in the early ambulatory stage performed significantly better (p< 0.001) than participants in the late non-ambulatory stage. CONCLUSION: The factors identified from the set of questionnaires provide a valid representation of upper extremity function, pain and stiffness in Duchenne muscular dystrophy. Based on the factor commonalities, the Upper Limb Short Questionnaire was formulated. Implications for Rehabilitation New insights into the underlying dimensions of upper extremity function, pain and stiffness in Duchenne muscular dystrophy are gained. Fourteen factors, with good internal consistency and construct validity, are identified regarding upper extremity function, pain and stiffness in Duchenne muscular dystrophy. Based on these factors, the Upper Limb Short Questionnaire is presented. The Upper Limb Short Questionnaire can be used as an identifier of arm-hand limitations and the start of more thorough clinical investigation.

Development of a Short Questionnaire to Assess Diet Quality among Older Community-Dwelling Adults.

OBJECTIVE: To evaluate the use of a short questionnaire to assess diet quality in older adults. DESIGN: Cross-sectional study. SETTING: Hertfordshire, UK. PARTICIPANTS: 3217 community-dwelling older adults (59-73 years). MEASUREMENTS: Diet was assessed using an administered food frequency questionnaire (FFQ); two measures of diet quality were defined by calculating participants' 'prudent diet' scores, firstly from a principal component analysis of the data from the full FFQ (129 items) and, secondly, from a short version of the FFQ (including 24 indicator foods). Scores calculated from the full and short FFQ were compared with nutrient intake and blood concentrations of vitamin C and lipids. RESULTS: Prudent diet scores calculated from the full FFQ and short FFQ were highly correlated (0.912 in men, 0.904 in women). The pattern of associations between nutrient intake (full FFQ) and diet scores calculated using the short and full FFQs were very similar, both for men and women. Prudent diet scores calculated from the full and short FFQs also showed comparable patterns of association with blood measurements: in men and women, both scores were positively associated with plasma vitamin C concentration and serum HDL; in women, an inverse association with serum triglycerides was also observed. CONCLUSIONS: A short food-based questionnaire provides useful information about the diet quality of older adults. This simple tool does not require nutrient analysis, and has the potential to be of value to non-specialist researchers.

Big Five Personality Trait Short Questionnaire: Preliminary Validation with Spanish Adults.

There are two major advantages of the Big Five Personality Trait Short Questionnaire (BFPTSQ) over other non-commercial short Five-Factor Model personality measures: widen conceptual breadth, and its use in both adolescents and adults. The aim of this study was to explore the psychometric properties of this questionnaire in an adult Spanish sample. Factor, convergent (using the NEO-PI-R), and criterion (using scales that assess happiness and alcohol consumption) validities, internal consistency as well as test-retest reliabilities of the BFPTSQ were evaluated. The sample was composed of 262 participants; a subsample of 71 individuals also answered the NEO-PI-R, and another subsample of 42 respondents filled the BFPTSQ out again a month later. The results indicated that the expected factor structure was recovered using exploratory structural equation modeling (ESEM). The ESEM showed satisfactory fit indices, with CFI and TLI around .90, as well as RMSEA and SRMR below .06. Moreover, coefficient alphas ranged from .75 to .85 and test-retest correlations ranged from .72 to .93 (p < .001). Regarding the associations of BFPTSQ with NEO-PI-R scales, the correlations with the broad-trait scales ranged from .57 to .80 (p < .001), and 27 out of 30 correlations with the facet scales were significant (p < .05 or lower). We also found that extraversion and emotional stability were associated with subjective well-being (p < .001), and extraversion and conscientiousness were related to alcohol consumption (p < .01). This study supports the construct validity of the Spanish version of the BFPTSQ in adults.

[Adaptation and validation of a brief screening questionnaire of depressive disorders in patients with cancer: Q2i study]. / Adaptation et validation d'un questionnaire à 2 items permettant le dépistage des troubles dépressifs chez les patients atteints de cancer : étude Q2i.

BACKGROUND: Depression is a sustainable state of deep sadness and abatement. It is frequently identified in patients with cancer and often undervalued by oncologists. The reduced PRIME-MD questionnaire is a questionnaire of 2 items validated in French. However, it has been neither translated nor validated in French. The objective of our study is to translate the PRIME-MD and validate it into French. METHOD: The PRIME-MD questionnaire was translated into French by using the recommendations of the EORTC and compared to the French gold standard questionnaire Mini-International Neuropsychiatric Interview (MINI). RESULTS: Two hundred and ninety-nine patients were included in our study. With a 98% filling rate, the Q2i questionnaire has been well accepted. The prevalence of depression in our population was measured at 7.4%. With a sensitivity of 89.47%, a specificity of 58.85%, found percentages are equal to those of the questionnaire in English. The negative predictive value was measured at 98.52%. CONCLUSION: This study demonstrates that the Q2i questionnaire is a quick and easy screening tool, requiring less than 2minutes to target patients likely to benefit from psychological support.

Cross-validation study using item response theory: the health-related quality of life for eating disorders questionnaire-short version.

The Health-Related Quality of Life for Eating Disorder-Short questionnaire is one of the most suitable existing instruments for measuring quality of life in patients with eating disorders. The objective of the study was to evaluate its reliability, validity, and responsiveness in a cohort of 377 patients. A comprehensive validation process was performed, including confirmatory factor analysis and a graded response model, and assessments of reliability and responsiveness at 1 year of follow-up. The confirmatory factor analysis confirmed the two second-order latent traits, social maladjustment, and mental health and functionality. The graded response model results showed that all items were good for discriminating their respective latent traits. Cronbach's alpha coefficients were high, and responsiveness parameters showed moderate changes. In conclusion, this short questionnaire has good psychometric properties. Its simplicity and ease of application further enhance its acceptability and usefulness in clinical research and trials, as well as in routine practice.
