SummaryObjective – To test the psychometric properties of the Italian version of the WHOQOL-BRIEF (e.g., construct and internal validity, concorrent validity with the MOS SF-36 and test-retest reliability). The WHOQOL-BRIEF is a 26-items self-report instrument which assesses four domains assumed to represent the Quality Of Life (QOL) construct: physical domain, psychological domain, social relationships domain and environment domain, plus two facets for assessing overall QOL and general health. Methods – Data have been collected in three sites (Bologna, Modena and Padua), located in the North of Italy, in the framework of the international WHOQOL project. According to the study design, the sample had to include about 50% males and 50% females, 50% of subjects below and 50% above the age of 45, all in contact with various health services. A subsample has been re-interviewed after 2-3 weeks in order to study test-retest reliability. After the WHOQOL-BRIEF, most subjects have also been administered the MOS-SF36 in order to test the concurrent validity between these two instruments. Results – The instrument was administered to 379 subjects (1/6 healthy and 1/6 sick), chosen to be representative of a variety of different medical conditions. Seventy patients, wTio displayed stable health conditions, have been reassessed after 2-3 weeks to study test-retest reliability. The WHOQOL-BRIEF domains has shown good internal consistency, ranging from 0.65 for the social relationships domain to 0.80 for the physical domain; it has been able to discriminate between in- and out-patients and between the two age groups considered in the present study (<45, ≥45 years). Only physical and psychological domains were found to discriminate between healthy and ill subjects. No gender differences in the mean scores for the four domains were found. Concurrent validity between the WHOQOL-Brief and the MOS-SF-36 was satisfactory, and specific for the physical and psychological health domains. Test-retest reliability values were also good, ranging from 0.76 for the environment domain to 0.93 for the psychological domain. Conclusions – This study shows that the WHOQOL-BRIEF is psychometrically valid and reliable, and that it is also potentially useful in discriminating between subjects with different health conditions in clinical settings.

Objective. The Geriatric Depression Scale (GDS) is an evaluation tool to diagnose older adult’s depression. This questionnaire was defined by Yesavage and Brink in 1982; it was designed expressly for the older person and defines his/her degree of satisfaction, quality of life, and feelings. The objective of this study is to evaluate the psychometric properties of the Italian translation of the Geriatric Depression Scale (GDS-IT). Methods. The Italian version of the Geriatric Depression Scale was administered to 119 people (79 people with a depression diagnosis and 40 healthy ones). We examined the following psychometric characteristics: internal consistency reliability, test-retest reliability, concurrent validity, and construct validity (factor structure). Results. Cronbach’s Alpha for the GDS-IT administered to the depressed sample was 0.84. Test-retest reliability was 0.91 and the concurrent validity was 0.83. The factorial analysis showed a structure of 5 factors, and the scale cut-off is between 10 and 11. Conclusion. The GDS-IT proved to be a reliable and valid questionnaire for the evaluation of depression in an Italian population. In the present study, the GDS-IT showed good psychometric properties. Health professionals now have an assessment tool for the evaluation of depression symptoms in the Italian population.

Objective Due to no existing data, we aimed to derive evidence to support test-retest reliability for the Health Assessment Questionnaire-Disability Index (HAQ-DI) and Medical Outcome Survey Short-Form-36 item physical functioning domain (SF-36 PF) in psoriatic arthritis (PsA). Methods We identified datasets that collected relevant data for test-retest reliability for HAQ-DI and SF-36 PF; and evaluated them using OMERACT Filter 2.1 methodology. We calculated intra-class correlation coefficients (ICC) as a measure of test-retest reliability. We then conducted a quality assessment and evaluated the adequacy of test-retest reliability performance. Results Two datasets were identified for HAQ-DI and one for SF-36 PF in PsA. The quality of the datasets was good. The ICCs for HAQ-DI were excellent in both datasets: 0.94 (95% CI: 0.88 to 0.97) and 0.94 (95% CI: 0.89 to 0.97). The ICC of SF-36 PF was good (0.89, 95% CI: 0.76 to 0.95). The performance of test-retest reliability for both instruments was judged to be adequate. Conclusion The new data derived support good and reasonable test-retest reliability for HAQ-DI and SF-36 PF in PsA.

Objective To translate and cross-culturally adapt the Arabic version of LupusPRO v.1.8 and to test its reliability and validity. Methods LupusPRO was translated into the Arabic language following a standard procedure with forward-backward translation and was tested in patients with systemic lupus erythematosus (SLE) before use. The Arabic version was administered to 107 Egyptian SLE patients, along with a validated Arabic version of RAND 36-Item Health Survey 1.0 (SF-36). The internal consistency and test-retest reliability were determined. Validity was assessed by correlating LupusPRO scores with SF-36, Safety of Estrogens in Lupus Erythematosus National Assessment–Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). The conceptual framework of the Arabic LupusPRO was evaluated using confirmatory factor analysis (CFA). Results Among the 107 SLE patients, 95% were women with a median (range) age of 32 (18-55) years, median (range) SELENA-SLEDAI of 6 (0-23) and median (range) SDI of 0 (0-6). The Cronbach's alpha for the Arabic LupusPRO ranged from 0.71 to 0.98, except for the social support domain (0.65). Test-retest reliability ranged from 0.95 to 0.99. Convergent validity with corresponding domains of SF 36 was satisfactory. For criterion validity, there was a weak but significant correlation between several LupusPRO domains with SELENA-SLEDAI. CFA showed a good model fit. Conclusion The Arabic version of LupusPRO v1.8 is a reliable and valid tool for measuring quality of life among Arabic speaking SLE patients.

Background: Patients who are in a coma, a vegetative state or a minimally conscious state present a clinical challenge for neurological assessment, which is a prerequisite for establishing a prognosis and planning management. Several scales have been developed to evaluate these patients. The Wessex Head Injury Matrix is a comprehensive tool but is currently available only in the French and English languages. The aim of this study was to translate and evaluate the reliability of the Italian version of the scale. Methods: The original scale was translated according to a standard protocol: three separate translations were made, and a selected version was back-translated to check for any errors in order to obtain the most accurate Italian translation. A final back translation of the agreed version was made as a further check. The final version was then administered blind to a consecutive series of patients with severe acquired brain injury by two examiners. Inter-rater and test-retest reliability were assessed using a weighted Cohen’s kappa (Kw). Concurrent validity of the WHIM was evaluated by ρ Spearman’s correlation coefficient using the Glasgow Coma Scale (GCS) and the Coma Recovery Scale Revised (CRS-R) as the available gold standard. Results: Twenty-four patients (12 males and 12 females; mean age 59.9 ± 20.1; mean duration from index event 17.7 ± 20.0 days) with stroke (n = 15), traumatic brain injury (n = 7) and anoxic encephalopathy (n = 2) were included. Inter-rater [Kw 0.80 (95% CI 0.75–0.84)] and test-retest reliability [Kw 0.77 (95% CI 0.72–0.81)] showed good values. WHIM total scores correlated significantly with total scores on the GCS (ρ = 0.776; p < 0.001) and the CRS-R (ρ = 0.881; p < 0.001) demonstrating concurrent validity; Conclusion: The Italian version of the scale is now available for clinical practice and research.

This study develops the Korean version of the Institute for Medical Technology Assessment Productivity Cost Questionnaire (iPCQ) through translation/cultural adaptation and evaluation of psychometric properties. We included 110 outpatients visiting a gynecology clinic. We conducted the translation and cross-cultural adaptation of the iPCQ, including forward and back-translation, pilot test with cognitive debriefing, and finalization. We analyzed the feasibility (using average time of filling in the iPCQ and the proportion of missing values), test–retest reliability (using the intra-class correlation coefficient [ICC]), and validity (concurrent validity with the Work Productivity and Activity Impairment [WPAI] and construct validity with the 36-Item Short Form Survey [SF-36], using Spearman’s ρ). The Korean version of iPCQ showed appropriate feasibility (average filling in time was 5.0 min without missing values), and had excellent values in the domains of absenteeism, presenteeism, and unpaid work for test–retest reliability (ICC: 0.92–0.99). For concurrent validity, the Korean version of iPCQ showed moderate–high correlation for absenteeism and presenteeism with the WPAI. All domains of productivity losses measured by the Korean version of iPCQ showed negative correlation with the quality of life estimated by the SF-36. Through this study, we developed a Korean instrument that can measure and value health-related productivity losses including unpaid work as well as absenteeism and presenteeism.

Background: Amyotrophic Lateral Sclerosis-Specific Quality of Life-Revised (ALSSQOL-R) encompasses 50 items which assess quality of life (QOL) in patients with amyotrophic lateral sclerosis (ALS) in six major domains. This study aims to translate the ALSSQOL-R into Persian and evaluate its reliability and validity among Iranian patients. Methods: ALSSQOL-R was translated by the standard multi-step forward-backward method. Content validity was calculated using item content validity index (I-CVI). Three items in the “intimacy” domain were deleted considering Iranian culture. Cronbach’s alpha was used for all 6 dimensions to calculate the internal consistency reliability. Test-retest reliability was evaluated using intraclass correlation coefficient (ICC) with one-month interval. Concurrent validity was measured by the validated version of 36-Item Short Form Health Survey (SF-36) questionnaire. Results: Sixty-three patients with ALS were enrolled in the study. I-CVI was 70%, promoted to 85% after modifications (acceptable). Regarding internal consistency reliability, Cronbach’s alpha in all six domains was  0.70 and total Cronbach’s alpha was 0.89 which is assumed as good. In terms of test-retest reliability, ICC [95% confidence interval (CI)] was 0.91 (91%) and Pearson correlation coefficient (r) was 0.90 (P < 0.001), all indicating an excellent reliability. The concurrent validity was established based on a strong correlation with SF-36 (r = 0.744, P < 0.001). Conclusion: The findings show that the modified

Background and Objectives. Health Related Quality of Life (HRQoL) is an important health outcome measure in haemophilia. The aim of this study was to assess the psychometric properties of the Greek version of Haem-A-QoL, a disease-specific questionnaire for haemophiliacs.Methods. Haem-A-QoL and SF-36 were administered to 118 adult haemophilia patients. Hypothesized scale structure, internal consistency (Cronbach’sα), and test-retest reliability, as well as various types of construct validity were evaluated.Results. Scale structure of Haem-A-QoL was confirmed, with good item convergence (87%) and discrimination (80.6%) rates. Cronbach’sαwas >0.70 for all but one dimension (dealing) and test-retest reliability was significantly high. The strength of Spearman’s correlations between Haem-A-QoL and SF-36 scales ranged from 0.25 to 0.75 (P<0.01). Multiple stepwise linear regression analysis revealed that all but one Haem-A-QoL dimensions were important predictors of SF-36 scales. Known-groups comparisons yielded consistent support of the instruments’ construct validity and significant relationships were identified for age, educational level, haemophilia type, disease severity, and viral infections.Conclusion. Overall, the psychometric properties of the Greek version of Haem-A-QoL, resulting from this first time administration of the instrument to Greek adult haemophiliacs, confirmed it as a reliable and valid questionnaire for assessing haemophilia-specific HRQoL in Greece.

Abstract Background Childhood obesity has increased remarkably in low and middle-income (LMIC) countries. Movement behaviors (physical activity, screen time, and sleep) are crucial in the development of overweight and obesity in young children. Yet, few studies have investigated the relationship between children’s movement behaviors and parenting practices because validated measures for use among families from LMIC are lacking. This study evaluated the psychometric properties of previously validated measures of young children’s physical activity, screen time, and sleep and parenting practices, translated and culturally adapted to Brazilian families. Methods A total of 78 parent-child dyads completed an interviewer-administered survey twice within 7 days. Child physical activity, sedentary time and sleep were concurrently measured using a wrist-worn accelerometer. Internal consistency and test-retest reliability was assessed using McDonald’s Omega and Intraclass Correlation Coefficients (ICC’s). Concurrent validity was evaluated by calculating Spearman correlations between parent reported child behaviors and accelerometer measured behaviors. Results Seventeen of the 19 parenting practices scales exhibited acceptable internal consistency reliability (Ω ≥ 0.70). Test-retest reliability ICC’s were acceptable and ranged from 0.82 - 0.99. Parent reported child physical activity was positively correlated with objectively measured total movement (rho= 0.29 - 0.46, p < .05) and energetic play (rho= 0.29 – 0.40, p < .05). Parent reported child screen time was positively correlated with objectively measured sedentary time; (rho = 0.26, p < .05), and inversely correlated with total movement (rho = - 0.39 – - 0.41, p < .05) and energetic play (rho = - 0.37 – - 0.41, p < .05). Parent reported night-time sleep duration was significantly correlated with accelerometer measured sleep duration on weekdays (rho = 0.29, p < .05), but not weekends. Conclusions Measurement tools to assess children’s movement behaviors and parenting practices, translated and culturally adapted for use in Brazilian families, exhibited acceptable evidence of concurrent validity, internal consistency, and test-retest reliability.
