Background: Generalised anxiety disorder (GAD) frequently occurs amongst patients with tuberculosis (TB) and contributes to poor quality of life and treatment outcomes. This study evaluated the construct validity and reliability of the GAD-7 scale in a sample of patients with TB in the Free State Province.Methods: A pilot study was conducted amongst a convenience sample of 208 adult patients newly diagnosed with drug-susceptible TB attending primary healthcare (PHC) facilities in the Lejweleputswa District in the Free State. A structured interviewer-administered questionnaire comprising social demographic questions and the GAD-7 scale was used. Confirmatory factor analysis was used to investigate the construct validity of the GAD-7 scale. The reliability of the scale was assessed by calculating Cronbach’s alpha.Results: The analysis showed that a modified two-factor (somatic symptoms and cognitive -emotional symptoms) model, in which the items ‘Not being able to stop or control worrying’ and ‘Worrying too much about different things’ were allowed to covary (Comparative Fit Index: 0.996, Tucker–Lewis Index: 0.993, Root Mean Square Error of Approximation: 0.070, 90% confidence interval: 0.032–0.089), fitted the data better than a unidimensional (generalised anxiety) or an unmodified two-factor model. The indicators all showed significant positive factor loadings, with standardised coefficients ranging from 0.719 to 0.873. The Cronbach’s alpha of the scale was 0.86.Conclusion: The modified two-factor structure and high internal consistency respectively provide evidence for construct validity and reliability of the GAD-7 scale for assessing GAD amongst patients with TB. Studies are necessary to assess the performance of this brief scale under routine TB programme conditions in the Free State.

Inadequate Health Literacy

OBJECTIVE: To develop and validate a short health literacy assessment tool for Portuguese-speaking adults. METHODS: The Short Assessment of Health Literacy for Portuguese-speaking Adults is an assessment tool which consists of 50 items that assess an individual's ability to correctly pronounce and understand common medical terms. We evaluated the instrument's psychometric properties in a convenience sample of 226 Brazilian older adults. Construct validity was assessed by correlating the tool scores with years of schooling, self-reported literacy, and global cognitive functioning. Discrimination validity was assessed by testing the tool's accuracy in detecting inadequate health literacy, defined as failure to fully understand standard medical prescriptions. RESULTS: Moderate to high correlations were found in the assessment of construct validity (Spearman's coefficients ranging from 0.63 to 0.76). The instrument showed adequate internal consistency (Cronbach's alpha=0.93) and adequate test-retest reliability (intraclass correlation coefficient=0.95). The area under the receiver operating characteristic curve for detection of inadequate health literacy was 0.82. A version consisting of 18 items was tested and showed similar psychometric properties. CONCLUSIONS: The instrument developed showed good validity and reliability in a sample of Brazilian older adults. It can be used in research and clinical settings for screening inadequate health literacy.

Background and Purpose: There are limited reliable and valid measures of the patient– provider interaction among adults with hypertension. Therefore, the purpose of this report is to describe the construct validity and reliability of the Questionnaire on the Quality of Physician–Patient Interaction (QQPPI), in community-dwelling adults with hypertension. Methods: A convenience sample of 109 participants with hypertension was recruited and administered the QQPPI at baseline and 8 weeks later. Results: The exploratory factor analysis established a 12-item, 2-factor structure for the QQPPI was valid in this sample. The modified QQPPI proved to have sufficient internal consistency and test– retest reliability. Conclusions: The modified QQPPI is a valid and reliable measure of the provider–patient interaction, a construct posited to impact self-management, in adults with hypertension.

Brazilian Children

The pictorial scale of Perceived Movement Skill Competence (PMSC) was developed to assess young children’s perceptions of competence in fundamental motor skills (FMS) and in active play (AP). The objectives of the present study were to assess validity and reliability with Brazilian children. Nineteen health-related professionals and 331 children (4 to 8 years old) were enrolled in the study. Kappa concordance coefficient, intra-class correlation coefficient (ICC), polychoric correlations, and confirmatory factor analyses (CFA) were used. The back-reverse translation prevents the bias of a single translation. Experts and professionals confirmed the clarity and pertinence of the items with high agreement scores (values > .90). Test-retest reliability results showed strong ICC (values > .90). The Cronbach’s alpha coefficient showed good internal consistency (α values from .70–.85). The CFA showed appropriate fit indexes for a three-factor model (i.e., six object control, six locomotion, and six AP items) and a two-factor model (i.e., 12 FMS and six AP items). However, the two-factor model showed superior indexes (χ2/df = 3.1; Root Mean Square Error of Approximation = .06; Goodness-Of-Fit Index = .90; Comparative Fit Index = .91; Akaike Information Criterion = 485.8). The PMSC is a valid and reliable assessment to use in Brazil.

Background: The aim of this study was to investigate the validity and reliability of the Korean version of the Suicide Opinion Questionnaire to measure Korean nurses’ attitudes toward suicide attempters.Methods: The questionnaire data were collected from 191 nurses who worked in emergency rooms, emergency wards and psychiatry wards. The internal consistency reliability and construct validity were evaluated using exploratory and confirmatory factor analysis.Results: The Cronbach’s α values regarding internal consistency were 0.51-0.79 for the subscales of the Korean version of the Suicide Opinion Questionnaire. The factor loadings of 18 items on the 6 subscales ranged from 0.54 to 0.84. The 6 subscale model was validated by a confirmatory factor analysis. The goodness-of-fit indexes were verified to be χ2/df = 1.56, root mean square residual = 0.04, goodness of fit index = 0.91, adjusted goodness of fit index = 0.86, Tucker-Lewis index = 0.9, comparative fit index = 0.92 and root mean squared error of approximation = 0.05.Conclusion: The findings indicated relatively satisfactory construct validity for the Korean version of the Suicide Opinion Questionnaire, whereas the reliability was not high. The current study indicates that the questionnaire should be used with caution when measuring nurses’ attitudes toward suicide attempters.

Task Satisfaction

It has been suggested that self-concept has both an evaluative and an affective dimension. Measures of self-concept, task satisfaction and performance were obtained from a sample of 188 Northern Irish university students. Using confirmatory factor analysis (LISREL 8), it was shown that, whereas a one-factor model did not fit the self-concept data, a two-factor model in which evaluative items loaded on one factor and affective items on the other, demonstrated a good fit (Incremental Fit Index (IFI) = 0.99). Further, a structural model in which evaluative self-concept was related to performance and affective self-concept was related to task satisfaction also fitted (IFI = 0.99). Thus, both the discriminant and construct validity of affective and evaluative self-concept were demonstrated. This may mean that previous studies have underestimated the magnitude of relationships between self-concept and other variables such as achievement.

Body-Esteem Scale is an assessment tool for adolescents and adults that evaluate three dimensions of self-evaluations of one&rsquo;s body. Body-Esteem Scale has been translated and validated in some countries since America down to Europe. Lack of translation and reliability evidence in Portugal was detected. This study aimed to translate and test the validity and reliability of the Body Esteem Scale for Adolescents and Adults (BESAA) in students in the context of Portuguese higher educa-tion. A total of 173 students (60.7% are female) with a mean age of 19.7 (standard deviation = 2.2) years participated. Categorical Principal Component Analysis was used to assess the underlying dimensions of BESAA. Construct validity was evaluated through correlation with the Appearance Schemas Inventory &ndash; Revised and a three-factor model (&ldquo;Appearance&rdquo;, &lsquo;&lsquo;Weight&rsquo;&rsquo; and &ldquo;Attribu-tion&rsquo;&rsquo;) was established. Confirmatory factor analysis was performed to verify the construct validity of the instrument. Items that had factor weights (&lambda;)&lt;.40 were removed, as well as those that were considered redundant by the modification indices estimated by the Lagrange Multipliers (LM) method (LM&gt;11, p&lt;.001). We observed high correlations between theoretically similar factors, and low correlations between different factors. The Portuguese BESAA showed adequate validity and reliability.

The objectives in this research were to determine the construct validity of both an adapted self-confidence questionnaire, the Personal Evaluation Inventory (PEI), developed by Shrauger and Schohn, and a Generalised Anxiety Disorder (GAD) questionnaire, which was adapted from the Taylor Manifest Anxiety Scale. The research was conducted in two girls&rsquo; primary schools in Saudi Arabia to collect relevant data on the convergent and discriminant validity of the GAD and PEI questionnaires using the Multi-Trait Multi-Method (MTMM) matrix to prove construct validity. Sixty students and two teachers filled in questionnaires, with each student evaluating themselves and, then, their peers. The teachers evaluated themselves, their self-confidence and generalised degree of their anxiety disorder. The results were that the MTMM analysis supported, to a large extent, both convergent and discriminant validity of the analysed data from students and teachers on two traits (self-confidence and generalised anxiety disorder) and across three methods of measurement (self-reporting, peer-rating and teacher-rating). The results were that the Mono-Trait Mono-Method coefficients were relatively high, and there was relative strength in the Hetero-Trait Mono-Method coefficients. The Hetero-Trait Mono-Method coefficients were reasonable for self-confidence and for the generalised anxiety disorder questionnaires, but teacher-ratings for both traits were unexpected. Furthermore, the Hetero-Trait Hetero-Method coefficients were not constant and showed an unstable variance. In conclusion, the PEI and GAD questionnaires possess acceptable construct validity, but that the teacher-ratings for both the PEI and the GAD questionnaires needed modification in order to attain the desirable construct validity.

Background and Purpose: The Modified Reminiscence Functions Scale (MRFS) measures the patterns and functions of reminiscence. The purpose of this study was to examine the factor structure of the MRFS in a sample of community-dwelling Black adults. Methods: A convenience sample (N= 335) of Black adults from the Northeast completed the 39-item MRFS. Seven- and 8-factor models were evaluated given the uncertainty regarding the number of factors in previous reminiscence research. Results: Confirmatory factor analysis established validity of the 7-factor model (relative chi-square [χ2/df] = 1.9, Tucker-Lewis index [TLI] = .919, comparative fit index [CFI] = .929, root mean square error of approximation [RMSEA] = .05). Reliability of the subscales ranged from .64 to .90. Conclusions: The MRFS is a reliable and valid measure of reminiscence patterns and functions in Black adults with similar characteristics.

Background: The Personal Wellbeing Index-Adults (PWI-A) is the most widely used instrument for measuring subjective-quality of life (QoL). The current study seeks to investigate the construct validity and reliability of the Arabic version of the PWI-A on adults with bilateral hearing impairment by comparing the single-factor solution with the two-factor solution. Methods: A cross-sectional study was conducted at the Audio-Vestibular Medicine Unit of Alexandria University from July-2017 to January-2018. A total of 205 adults were interviewed to measure the subjective-QoL using the PWI-A instrument. Internal consistency was determined using both Cronbach’s alpha and composite reliability (CR). Validity was assessed by construct validity, including ordinal regression, ordinal exploratory factor analysis (OEFA), and ordinal confirmatory factor analysis (OCFA). Results: The first four items of the PWI-A which are: satisfaction with living standard, health, achievements, and relationships were the most important indicators of subjective-wellbeing (Part r2 0.0547, 0.0324, 0.0361, and 0.0225, respectively). OEFA suggested that the two-factor model contributes better than the single-factor model. OCFA validated this suggested solution; (two-factor: RMSEA=0.084 (90% CI=0.01-0.14); CFI=0.964; AIC=52.64; single-factor: RMSEA=0.119 (90% CI=0.07-0.17); CFI=0.922; AIC=62.77). Good internal consistency was also presented (two-factor: Cronbach’s alpha=0.719, 0.693; single-factor: Cronbach’s alpha = 0.750). Conclusion: The Arabic version of the PWI-A is a multidimensional scale that consists of two dimensions: the first is related to subjective-QoL, and the second is related to satisfaction with the community. Thus, it is recommended to use the short version of the PWI-A with only four items to measure subjective-QoL, as it achieved sufficient reliability and construct validity.
