Abstract Background The 12-item Medical Outcomes Study Sleep Scale (MOS Sleep Scale) has been used to capture patient-reported sleep problems in hundreds of studies. A revised version of the MOS Sleep Scale (MOS Sleep-R) was developed that uses simplified response sets, provides interpretable norm-based scoring, and has two recall versions (one-week or four-week). The objective of this study was to evaluate the psychometric properties (reliability and construct validity) of the MOS Sleep-R using data from a representative sample of U.S. adults. Methods Standardization of raw scores into norm-based T-scores (mean = 50, standard deviation = 10) was based on data from a 2009 U.S. internet-based general population survey. The internal consistency reliability of multi-item subscales and global sleep problems indices for both one-week and four-week recall forms of the MOS Sleep-R were examined using Cronbach’s alphas and inter-item correlations. Construct validity was tested by comparing item-scale correlations between items within subscales with item-scale correlations across subscales. Scale-level convergent validity was tested using correlations with measures including generic health-related quality of life (i.e., SF-36v2) and other relevant outcomes (e.g., job performance, number of days in bed due to illness or injury, happiness/satisfaction with life, frequency of stress/pressure in daily life, the impact of stress/pressure on health, and overall health). Results The one-week and four-week recall forms of the MOS Sleep-R were completed by 2045 and 2033 respondents, respectively. The psychometric properties of the one-week and four-week forms were similar. All multi-item subscales and global index scores showed adequate internal consistency reliability (all Cronbach’s alpha > 0.75). Patterns of inter-item and item-scale correlations support the scaling assumptions of the MOS Sleep-R. Patterns of correlations between MOS Sleep-R scores with criterion measures of health-related quality of life and other outcomes indicated adequate construct validity. Conclusions The MOS Sleep-R introduces a number of revisions to the original survey, including simplified response sets, the introduction of a one-week recall form, and norm-based scoring that enhances interpretability of scores. Both the one-week and four-week recall period forms of the MOS Sleep-R demonstrated good internal consistency reliability and construct validity in a U.S. general population sample.

Abstract Background The objective of this study was to verify the reliability, discriminatory power and construct validity of the Kidscreen-27 questionnaire in Brazilian adolescents. Methods Adolescents that participated of the pilot study (210 adolescents; 52.9% boys; 13.7 years old) and of the baseline (816 participants; 52.7% girls; 13.1 years old) of the Movimente Project in 2016/2017 composed the sample of the present study. This project was carried out in six public schools in the city of Florianópolis, Santa Catarina, Brazil. Test–retest reproducibility was assessed by the intraclass correlation coefficient and Gwet coefficient; internal consistency through McDonald's Omega; Hankins' Delta G coefficient verified the scale's discriminatory power and; confirmatory factor analysis to assess construct validity. Results Reproducibility values ranged from 0.71 to 0.78 for the dimensions (ICC), and ranged from 0.60 to 0.83 for the items (Gwet). McDonald's Ômega (0.82–0.91) for internal consistency measures. Discriminatory power ranging from 0.94 for the dimension Social Support and Friends to 0.98 for Psychological Well-Being. The factorial loads were > 0.40, except for item 19 (0.36). The fit quality indicators of the model were adequate (X2[df] = 1022.89 [311], p < 0.001; RMSEA = 0.053 (0.049–0.087); CFI = 0.988; TLI = 0.987), confirming the five-factor structure originally proposed. Conclusions The Brazilian-version Kidscreen-27 achieved good levels of reproducibility, internal consistency, discriminatory power and construct validity. Its use is adequate to measure the health-related quality of life of adolescents in the Brazilian context.

Abstract Background Inflammatory bowel disease (IBD) affects several dimensions of health-related quality of life. The IBD-Disk scale was designed to provide immediate illustration of disability reported by patients with IBD, previously validated in two cohort studies. The aim of this study is to validate the IBD-Disk in a Portuguese cohort in a clinical setting according to the COnsensus-based Standards for the selection of the health Measurement INstruments (COSMIN) recommendations. Methods After translation to Portuguese, a group of IBD patients was invited to fill-in the IBD-Disk at baseline (T0), after 2 weeks (T1), and after 3 months (T2), from July 2020 to February 2021. At T0 and T2 the patients also completed the IBD-Disability Index. We evaluated reliability (internal consistency, test-retest, and inter-rater reliability and measurement error), construct validity, responsiveness, and interpretability. Results At baseline, 154 patients (107 - Crohn′s disease; 46 - ulcerative colitis) completed the IBD-Disk. After 2 weeks and 3 months, 64 and 114 patients repeated the questionnaire, respectively. Factor analysis confirmed the unidimensionality of the scale and reduced the final version to 10 items. Internal consistency was excellent with a Cronbach’s α of 0.916. The intraclass correlation coefficient was 0.95 for test-retest (baseline and 2 weeks). To evaluate construct validity, the IBD-Disk was compared with the IBD-Disability Index with a significative positive correlation (r=0.850; p&lt;0.001). IBD-Disk scores ranged from 0 to 93 with a mean of 38.18±25.39. Female gender (β =0,3; p&lt;0,001) and professional inactivity (β=0.28, p=0.014) were associated with higher IBD-Disk scores. Neither floor nor ceiling effects were observed. Conclusion The Portuguese version of IBD-Disk is a reliable, valid, and responsive tool to assess disability in Portuguese IBD patients. This study confirms the utility of this instrument in the evaluation of IBD patients in diverse populations.

Objective: Several recent studies have documented that substantial functional impairment is associated with many of the mental disorders seen in primary care. However, brief measures of mental health-related functional impairment are not commonly applied in primary care settings. The Sheehan Disability Scale (SDS), a three-item instrument for assessing such impairment, is evaluated in this study. Method: A psychometric analysis of the SDS was conducted with a sample of 1001 primary care patients at Kaiser Permanente in Oakland, California. The SDS and the Symptom Driven Diagnostic System for Primary Care assessments were completed. Results: The internal consistency reliability of the SDS is high, with coefficient alpha of 0.89. The construct validity was substantiated in two ways. A one-factor model fit the data quite well. Furthermore, patients with each of six psychiatric disorders had significantly higher impairment scores than those who did not. Finally, over 80 percent of the patients with mental disorder diagnoses had an elevated SDS score and nearly 50 percent of those with elevated SDS scores had at least one disorder. Conclusions: The psychometric properties of the SDS were evaluated in primary care. The internal consistency reliability was high. The analyses also lend empirical support for the construct validity. The scale is a sensitive tool for identifying primary care patients with mental health-related functional impairment, who would warrant a diagnostically-oriented mental health assessment.

Aging Males Symptoms

This study was to assess whether the Chinese version of the Aging Males' Symptoms scale could measure aging men's symptoms as effectively as the English version. 176 psychiatric outpatient men were assessed to analyze internal consistency reliability and construct validity, and 45 male school staff were interviewed in estimating retest reliability. Cronbach a was .90, and the 3-wk. retest reliability was .72. Factor analysis yielded a two-factor structure. Construct validity was indicated by significant correlation between the two factors and the criterion variables. This scale is a validated and sensitive test for measuring symptoms in aging men in the Taiwanese Chinese-speaking population. It is suggested that the scale could be used to measure and compare health-related quality of life in groups of men over 40 years old.

Purpose: Three aims were addressed: (a) Evaluate properties of the items comprising the Life Changes in Epilepsy Scale-Pilot (LCES-P), (b) use item analysis to optimize the scale, (c) evaluate construct and criterion-related validity of the optimized LCES. Methods: The LCES-P was administered to 174 adults with epilepsy. Item analysis and exploratory factor analysis were performed. Internal consistency reliability, construct validity, and criterion-related validity were evaluated. Results: 17 items were retained in the optimized LCES. Internal consistency reliability was supported. Path analysis was used to evaluate construct validity. Criterion-related validity was supported by correlations with the Medical Outcomes SF-36 Survey (SF-36) General Health subscale and a criterion variable. Conclusions: The optimized version of the LCES can serve as a valuable outcome measure in clinical and research environments.

Abstract Background Torture methods have traditionally been quantified using checklists. However, checklists fail to capture accurately both the almost infinite range of available methods of torture and the victims’ subjective experience. The Torturing Environment Scale (TES) was designed as a multidimensional alternative that groups torture methods according to the specific human function under attack. This study aims to do an exploratory assessment of the internal consistency reliability and discriminatory validity of the TES as part of a construct validity assessment in a sample of Basque torture survivors. Methods We applied the TES to a sample of 201 torture survivors from the Istanbul Protocol Project in the Basque Country Study (IPP-BC) to profile torturing environments in detention. To estimate the internal consistency reliability of the scale, categorical omega values were obtained for each subscale of the TES. To assess its discriminatory validity, the “known groups” method was used comparing mean scorings by gender, state security forces involved in the detention, and decade (the 1980s to the present) when the events took place. Results Men reported more physical pain, while women reported more attacks on self-identity and sexual integrity. The TES also showed significant differences as regards the security forces involved in the detention: Civil Guard (a militarised police) used more manipulation of the environment, threats, fear, pain and extreme pain, as compared to national and regional corps. Finally, although patterns of torture remained mostly unchanged across decades, more recent detentions included more emphasis on psychological attacks: context manipulation, humiliation linked to sexual identity, and attacks to meaning and identity. For all subscales of the TES, categorical omega values ranged from 0.44 to 0.72. Conclusion The TES may be a useful tool in profiling torturing environments. Its sensitivity to key contextual variables supports the discriminatory validity of the scale. While some of the subscales showed an acceptable degree of internal consistency, others require further analysis to improve reliability. The scale provides unique insights into the profile of contemporary torture. It will allow for future quantitative research on the relationship between different torturing environments and the medical and psychological consequences thereof.

This paper describes a 64-item clinical screening task designed to assess the accuracy of children's consonant cluster productions. This procedure is designed to help speech-language pathologists develop intervention programs to improve children's production of clusters by facilitating the identification of error patterns. Once such patterns have been identified, individualized treatment programs designed to maximize generalization may be developed. The task was administered to 100 4- and 5-year-old subjects to assess the technical adequacy of the procedure. Internal consistency reliability of the task was high, and the procedure was also shown to assess an appropriately diverse array of word-initial and word-final consonant clusters. Finally, the construct validity of the task was supported by factor analytic procedures.

IntroductionChildren with sickle cell disease (SCD) can present a variety of clinical symptoms that may affect their sleep and health-related quality of life (HRQOL). This study aims to investigate the relation between sleep problems and HRQOL in children and adolescents with SCD.Material and methodsThe sample included 86 children and adolescents in the SCD patient group and 82 healthy controls, with an age range of 8-16 years. Subjects for the study were recruited from the Sickle Cell and Thalassemia Center of Hatay State Hospital, Hatay, Turkey. The Children’s Sleep Habits Questionnaire (CSHQ) was used to evaluate sleep problems and Kinder Lebens­qualitätsfragebogen: Children’s Quality of Life Questionnaire – revis­ed (KINDL-R) was used to examine HRQOL.ResultsTotal score, bedtime resistance, and night waking subscores of CSHQ were significantly higher in children with SCD when compared to healthy children. Total score, physical well-being, emotional well-being, social, and school subscores of KINDL-R were significantly lower in the patient group. Among SCD children, total score, bedtime resistance, sleep onset delay, daytime sleepiness, and parasomnias subscores of CSHQ were negatively correlated with KINDL-R total score. In the regression model, disease severity and CSHQ total score had significant negative associations with KINDL-R total score.ConclusionsSleep problems in SCD children appear to be negatively linked with HRQOL. Disease severity and sleep problems may be predictors of overall HRQOL in children and adolescents with SCD.
