Abstract Background Although there is emerging data regarding the psychometric properties of the Child Health Utility-9D instrument, more evidence is required with respect to its validity for use in different country settings. The aim of this study was to examine the construct validity of the CHU-9D-CHN instrument in Chinese children. Methods Baseline Health-Related Quality of Life (HRQoL) and demographic data were collected from children recruited to the CHIRPY DRAGON obesity prevention intervention randomised controlled trial in China. HRQoL was measured using the Chinese version of the CHU-9D instrument (CHU-9D-CHN) and the PedsQL instrument. CHU-9D-CHN utility scores were generated using two scoring algorithms [UK and Chinese tariffs]. Discriminant validity, known-group validity and convergent validity were evaluated using non-parametric test for trend, Kruskal–Wallis test and Spearman correlation coefficient analysis respectively. Results Data was available for 1,539 children (mean age 6 years). The CHU-9D-CHN was sensitive to known group differences determined by the median PedsQL total score. Furthermore, the mean CHU-9D-CHN utility values decreased linearly with increasing levels of severity on each dimension of the PedsQL for emotional and social functioning domains. They decreased monotonically with increasing levels of severity on each dimension of the PedsQL for physical and school functioning domains (p < 0.001). Contrary to studies conducted in Western countries, and although not statistically significant, we found an indication that HRQoL, using both the CHU-9D-CHN and the PedsQL, was higher in children whose parents had lower levels of education, compared to those whose parents were university educated. The correlation between the CHU-9D-CHN utility values using UK and Chinese tariffs, and PedsQL total scores showed a statistically significant moderate positive correlation (Spearman’s rho = 0.5221, p < 0.001 and Spearman’s rho = 0.5316, p < 0.001), respectively. However, each CHU-9D-CHN dimension was either weakly, or very weakly correlated with each of the predetermined PedsQL domain functioning scores. Conclusions Overall, the findings provide some support for the construct validity of the CHU-9D-CHN within a Chinese population aged 6–7 years. However, some uncertainty remains. We recommend future studies continue to test the validity of the CHU-9D in different country settings. Trial registration: ISRCTN Identifier ISRCTN11867516, Registered on 19/08/2015

Abstract Objectives The Child Health Utility 9D (CHU9D) currently represents the only preference-based health-related quality-of-life instrument designed exclusively from its inception for application with children. The objective of this study was to examine the construct validity and responsiveness of the proxy-reported (parent) CHU9D in a mental health setting using utility weights derived from an adult and adolescent population, respectively. Methods The discriminant validity and convergent validity were examined using the mental health-specific ‘The Strengths and Difficulties Questionnaire’ (SDQ) and the generic KIDSCREEN-27. Responsiveness was assessed by examining the floor-ceiling effects, the magnitude of change over time, and the ability to differentiate between improvement and no improvement. Results The study included 396 children with mental health problems. CHU9D showed good construct validity, with correlation coefficients ranging between 0.329 and 0.571 for SDQ Impact score and KIDSCREEN-27 Psychological Well-being. CHU9D was able to distinguish between groups of children with different levels of mental health problems (p < 0.001). The absolute magnitudes of the group mean differences were larger using adolescent weights. No evidence of a floor/ceiling effect was found at the baseline. A standardized response mean of 0.634–0.654 was found for the children who experienced clinically significant improvements. CHU9D was able to discriminate between children who experienced positive and no health improvements (p < 0.001). Conclusion This study provides the first evidence on responsiveness for CHU9D in a mental health context. The findings demonstrate that CHU9D is an appropriate HRQOL measure for use in mental health trials. Furthermore, the results show that the preference weights generated from an adolescent population resulted in the larger mean differences between groups.

Development Step

This study aimed to develop an instrument for measuring the attitudes that reflect the characteristics of the pandemic (Adult Pandemic Attitude Scale (A-PAS)) and verifying its validity and reliability. This study used a methodological research design and was conducted with a development step and an evaluation step. The development step included development of preliminary items, content validity, face validity, and preliminary investigation. The evaluation step included item analysis, construct validity, convergent validity, discriminant validity, criterion validity, factor naming, reliability, and completion of the final instrument. The A-PAS developed in this study consisted of a total of 20 items in five dimensions. The internal consistency of 20 items of the A-PAS, Cronbach’s α was 0.92 for 20 items, Cronbach’s α for each factor, a subscale of instrument, was 0.61~0.87 and Raykov’s p coefficient of each factor, which is a subscale of the tool, was found to be 0.60 to 0.88. Analysis of construct validity showed the results as follows: χ2 (p) = 134.05 (p < 0.001), RMSEA = 0.02, RMR = 0.02, GFI = 0.94, CFI = 0.99. The study findings suggest that the developed instrument can be utilized to measure the attitudes of adults toward pandemics, and reflect the reality of the pandemic situation. The outcomes can be used as valuable data for intervention, prevention activities, and policy preparation. The instrument will be applied in the event of a pandemic, such as COVID-19, and will be helpful in promoting the health of the people.

Purpose Standardized clinical assessment of dysarthria is essential for management and research. We present a new, fully standardized dysarthria assessment, the Bogenhausen Dysarthria Scales (BoDyS). The measurement model of the BoDyS is based on auditory evaluations of connected speech using 9 scales (traits) assessed by 4 elicitation methods. Analyses of the BoDyS' reliability and construct validity were performed to test this model, with the aim of gauging the auditory dimensions of speech impairment in dysarthria. Method Interrater agreement was examined in 70 persons with dysarthria. Construct validity was examined in 190 persons with dysarthria using a multitrait-multimethod design with confirmatory factor analysis. Results Interrater agreement of < 1 on a 5-point scale was found in 91% of cases across listener pairs and scales. Average reliability was .85. Inspection of the multitrait-multimethod matrix pointed at a high convergent and discriminant validity. Modeling of the BoDyS trait and method factors using confirmatory factor analysis yielded high goodness of fit. Model coefficients confirmed high discriminant and convergent validity and revealed meaningful relationships between scales and methods. Conclusions The 9 auditory scales of the BoDyS provide a reliable and valid profile of dysarthric impairment. They permit standardized measurement of clinically relevant dimensions of dysarthric speech.

The Physical Self-Description Questionnaire (PSDQ) is a multidimensional physical self-concept instrument with 11 scales: Strength, Body Fat, Activity, Endurance/Fitness, Sports Competence, Coordination, Health, Appearance, Flexibility, Global Physical, and Global Esteem. The purpose of this study is to evaluate the construct validity of PSDQ responses in relation to 23 external criteria, including measures of body composition, physical activity, endurance, strength, and flexibility for 192 (113 boys and 79 girls) high school students. Each external validity criterion was predicted a priori to be most highly correlated with one of the PSDQ scales. In support of the convergent validity of the PSDQ responses, every predicted correlation was statistically significant. In support of the discriminant validity of the PSDQ responses, most predicted correlations were larger than other correlations involving the same criterion. These results support the construct validity of PSDQ responses in relation to external criteria and their potential usefulness in a wide variety of sports and exercise settings.

AbstractCognitive reserve is a hypothetical construct that has been used to inform models of cognitive aging and is presumed to be indicative of life experiences that may mitigate the effects of brain pathology. The purpose of this study was to evaluate the construct validity of cognitive reserve by examining both its convergent and its discriminant validity across three different samples of participants using structural equation modeling. The cognitive reserve variables were found to correlate highly with one another (thereby providing evidence of convergent validity), but demanding tests of discriminant validity indicated that, in two of the samples, the cognitive reserve construct was highly related to an executive functioning construct.

Purpose Although Colquitt’s Organizational Justice Scale (COJS) is one of the most widely used organizational justice scales (OJS) worldwide, a rigorous adaptation and validation in Italy is still missing. Accordingly, the purpose of this paper is to examine the construct validity and reliability of the Italian translation of the scale. Design/methodology/approach Factorial and concurrent validity were examined to assess construct validity. A confirmatory factorial analysis through structural equation modelling was conducted on five factorial models: one-factor, two-factor, three-factor, four-factor and second-order factor model. Concurrent validity implied the examination of the relationships between organizational justice and job satisfaction (convergent validity) and between organizational justice and workplace bullying (discriminant validity). Findings Evidence of the prevalence of the original Colquitt (2001) four-factor model was found, though also the second-order model obtained adequate goodness of fit. Findings supported both convergent and discriminant validity. Reliability analysis reported evidence of excellent internal consistency. Thus, the Italian version of the OJS can be used in Italy for research and practical purposes. Originality/value This is the first study properly addressing the factorial and concurrent validity of the OJS in Italy.

Objective: This study examined the construct validity of the Enfranchisement scale of the Community Participation Indicators. Design: We conducted a secondary analysis of data collected in a cross-sectional study of rehabilitation outcomes. Subjects: The parent study included 604 community-dwelling adults with chronic traumatic brain injury, stroke, or spinal cord injury. The sample had a mean age of 64.1 years, was two-thirds male, and included a high proportion of racial minorities ( n = 250, 41.4%). Main measures: The Enfranchisement scale contains two subscales: the Control subscale and the Importance subscale. We examined correlations between each Enfranchisement subscale and measures of participation, environment, and impairments. The current analyses included cases with at least 80% of items completed on each subscale (Control subscale: n = 391; Importance subscale: n = 219). Missing values were imputed using multiple imputation. Results: The sample demonstrated high scores, indicating poor enfranchisement (Control subscale: M = 51.7; Importance subscale: M = 43.0). Both subscales were most strongly associated with measures of participation (Control subscale: r = 0.56; Importance subscale: r = 0.52), and least strongly associated with measures of cognition (Control subscale: r = 0.03; Importance subscale: r = 0.03). The Importance subscale was closely associated with depression ( r = 0.54), and systems, services, and policies ( r = 0.50). Both subscales were associated with social attitudes (Control subscale: r = 0.44; Importance subscale: r = 0.44) and social support (Control subscale: r = 0.49; Importance subscale: r = 0.41). Conclusions: We found evidence of convergent validity between the Enfranchisement scale and measures of participation, and discriminant validity between the Enfranchisement scale and measures of disability-related impairments. The analyses also revealed the importance of the environment to enfranchisement outcomes.

Background and Purpose: This study aimed to evaluate the reliability and the construct validity of the Brazilian version of the Self-Efficacy for Appropriate Medication Adherence Scale (SEAMS). Methods: One hundred forty-seven patients with coronary artery disease participated in the study. Reliability was estimated by composite reliability (CR). Convergent validity was estimated by the factor loading and average variance extracted (AVE). The discriminant validity was assessed by cross-factor loadings, comparing the square roots of AVEs by correlation coefficients between latent constructs and disattenuated correlation. Results: The values of CR of .88 and .99 for Factors 1 and 2, respectively, indicate internal consistency reliability. Values of AVE = 0.52 for Factor 1 and 0.69 for Factor 2 to the convergent validity of the model. Cross-factor loadings were found ≥.50 for all items of the scale in areas that were allocated in the original instrument, square roots of AVEs higher than the correlations between the constructs and desatenuada correlation (r = .83), suggesting discriminant validity fashion model. Conclusion: Confirmatory factor analysis partially yielded the construct validity of the Brazilian version of the SEAMS.

AbstractThe n-back task is a widely used neuroimaging paradigm for studying the neural basis of working memory (WM); however, its neuropsychometric properties have received little empirical investigation. The present study merged clinical neuropsychology and functional magnetic resonance imaging (fMRI) to explore the construct validity of the letter variant of the n-back task (LNB) and to further identify the task-evoked networks involved in WM. Construct validity of the LNB task was investigated using a bootstrapping approach to correlate LNB task performance across clinically validated neuropsychological measures of WM to establish convergent validity, as well as measures of related but distinct cognitive constructs (i.e., attention and short-term memory) to establish discriminant validity. Independent component analysis (ICA) identified brain networks active during the LNB task in 34 healthy control participants, and general linear modeling determined task-relatedness of these networks. Bootstrap correlation analyses revealed moderate to high correlations among measures expected to converge with LNB (|ρ|≥0.37) and weak correlations among measures expected to discriminate (|ρ|≤0.29), controlling for age and education. ICA identified 35 independent networks, 17 of which demonstrated engagement significantly related to task condition, controlling for reaction time variability. Of these, the bilateral frontoparietal networks, bilateral dorsolateral prefrontal cortices, bilateral superior parietal lobules including precuneus, and frontoinsular network were preferentially recruited by the 2-back condition compared to 0-back control condition, indicating WM involvement. These results support the use of the LNB as a measure of WM and confirm its use in probing the network-level neural correlates of WM processing. (JINS, 2014, 20, 1–15)

Purpose: The aim of this study was to evaluate the psychometric properties of the Beliefs Toward Mental Illness Scale (BMI) across women from the United States, Japan, and South Korea. Methods: A cross-sectional study design was employed. The sample was 564 women aged 21–64 years old who were recruited in the United States and Korea (American = 127, Japanese immigrants in the United States = 204, and Korean = 233). We carried out item analysis, construct validity by confirmatory factor analysis (CFA), and internal consistency using SPSS Version 22 and AMOS Version 22. Results: An acceptable model fit for a 20-item BMI (Beliefs Toward Mental Illness Scale–Revised [BMI-R]) with 3 factors was confirmed using CFA. Construct validity of the BMI-R showed to be all acceptable; convergent validity (average variance extracted [AVE] ≥0.5, construct reliability [CR] ≥0.7) and discriminant validity (r = .65–.89, AVE >.79). The Cronbach’s alpha of the BMI-R was .92. Conclusion: These results showed that the BMI was a reliable tool to study beliefs about mental illness across cultures. Our findings also suggested that continued efforts to reduce stigma in culturally specific contexts within and between countries are necessary to promote help-seeking for those suffering from psychological distress.
