Performance of the Reported and Intended Behavior Scale among Colombian Adolescents

Objective: To establish the Reported and Intended Behavior Scale (RIBS) psychometric performance, a mental disorder-related stigma measurement, among Colombian adolescents. Methods: A validation study was carried out with 350 students aged between 10 and 17, 53.7% of whom were girls. The RIBS has two sub-scales -reported behaviors and intended behaviors, with four items each. Frequencies were estimated for reported behaviors, whereas internal consistency (Cronbach's alpha and McDonald's omega) and confirmatory factor analysis (CFA) were measured for intended behaviors. Results: The reported behavior sub-scale ranged from 10.0 to 24.9%, whereas the intended behavior sub-scale presented a Cronbach's alpha of 0.88 (CI95% 0.86-0.90) and a McDonald's omega of 0.88. For the CFA, KMO was 0.81; Bartlett chi squared, 771.1 (df=6, p=0.01); and Eigen value, 2.95 that explained 73.9% of the total variance. For the goodness-of-fit tests, chi squared was 21.9 (df=2, p=.001); RMSEA, 0.17 (CI90% 0.11-0.24); CFI, 0.97; TLI, 0.92; and SMSR, 0.03. Conclusions: The RIBS can measure reported behaviors, and the intended behavior sub-scale shows high internal consistency. However, the dimensionality of the intended behavior sub-scale presents modest goodness-of-fit indexes. These findings need further replications.

The Multiple Sclerosis Work Difficulties Questionnaire-23 (MSWDQ-23) is a self-report instrument developed to assess barriers faced by People with Multiple Sclerosis (PwMS) in the workplace. The aim of this study was to explore the psychometric properties of the Greek version of the MSWDQ-23. The study sample consisted of 196 PwMS, all currently working in part- or full-time jobs. Participants underwent clinical examination and cognitive screening with the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) and completed self-report measures of fatigue, psychological functioning, and quality of life, along with the MSWDQ-23 questionnaire. Confirmatory Factor Analysis (CFA) was performed, and goodness-of-fit measures were used to evaluate construct validity. Convergent validity was checked by correlating MSWDQ-23 scores with study measures. Cronbach’s alpha value was produced to assess internal consistency. CFA yielded a model with a fair fit confirming the three-factor structure of the instrument. Higher work difficulties were associated with higher Expanded Disability Status Scale (EDSS) scores, poorer cognitive function, more fatigue, stress, anxiety, and depression, and poorer health status, supporting the convergent validity of MSWDQ-23. Internal consistency (Cronbach’s alpha = 0.94) and test–retest reliability (ICC = 0.996, 95%, CI = 0.990–0.998) were excellent. The Greek MSWDQ-23 can be considered a valid patient-reported outcome measure and can be used in interventions aiming to improve the vocational status of PwMS.

Objectives: The aim of this study was to develop and validate a DCG assessment framework for use in local dental schools in Iran. Methods: A mixed method (qualitative and quantitative) was used in the present investigation. The study was performed in 3 steps, including: a) thorough literature review, b) focused group discussion and c) Application of validated instrument. The content validity index (CVI) and content validity ratio (CVR) were calculated for each question. The Cronbach's alpha coefficient was calculated to evaluate the internal consistency and reliability for this questionnaire. The Smart PLS software was used for calculation of Goodness of Fit (GOF) for confirmatory factorial analysis to determine construct validity of this questionnaire. Results: Initially, 140 items covering 7 DCG domains were identified after comprehensive literature review. Ten specialists participated in the expert panel, rating independently on the necessity, relevancy, simplicity and clarity of each question. Expert’s ratings were used to calculate the validity for each question. The questions with CVI lower than 0.79 and the CVR less than 0.62 were excluded. Reliability analysis was conducted by calculating intra class coefficient (ICC) and Cronbach's alpha coefficient which were 0.88 and 0.92 respectively. This shows good reliability and internal consistency of the questionnaire. Construct validity determined by computing Goodness of Fit index. The result was 0.622, which indicates a good level of construct validity. After validation process, 124 out of 140 questions left to cover the 7 domains of DCG in our newly developed and validated framework. Conclusions: The newly developed and standardized DCG framework can be used for assessment of compliance level among Iranian dental schools at the national level.

ObjectiveThe lack of a validated and cross-culturally equivalent scale for measuring individual-level water insecurity has prevented identification of those most vulnerable to it. Therefore, we developed the 12-item Individual Water InSecurity Experiences (IWISE) Scale to comparably measure individual experiences with access, use, and stability (reliability) of water. Here, we examine the reliability, cross-country equivalence, and cross-country and within-country validity of the scale in a cross-sectional sample.MethodsIWISE items were implemented by the Gallup World Poll among nationally representative samples of 43 970 adults (>15 y) in 31 low-income and middle-income countries (LMICs). Internal consistency was assessed with Cronbach’s alpha. Equivalence was tested using multigroup confirmatory factor analysis (MGCFA), the alignment method, and item response theory. Cross-country validity was assessed by regressing mean national IWISE scores on measures of economic, social, and water infrastructure development. Within-country validity was tested with logistic regression models of dissatisfaction with local water quality by IWISE score and regressing individual IWISE scores on per capita household income and difficulty getting by on current income.FindingsInternal consistency was high; Cronbach’s alpha was ≥0.89 in all countries. Goodness-of-fit statistics from MGCFA, the proportion of equivalent item thresholds and loadings in the alignment models, and Rasch output indicated equivalence across countries. Validity across countries was also established; country mean IWISE scores were negatively associated with gross domestic product and percentage of the population with access to basic water services, but positively associated with fertility rate. Validity within countries was also demonstrated; individuals’ IWISE scores were positively associated with greater odds of dissatisfaction with water quality and negatively associated with lower financial standing.ConclusionsThe IWISE Scale provides an equivalent measure of individual experiences with water access and use across LMICs. It will be useful for establishing and tracking changes in the prevalence of water insecurity and identifying groups who have been ‘left behind’.

Abstract Background: Nutrition literacy has a positive effect on health and its measurement has no consensus.This study was performed to develop the Chongqing Middle school student Nutrition Literacy Scale(CM-NLS)and measure its reliability and validity.Methods: Three experiments were conducted. Firstly, a theoretical framework and an initial item pool of CM-NLS were established based on the literature review. Secondly, the two-round Delphi method was used to explore the suitable acceptance indicators and items. Thirdly, item evaluation and reduction were performed using the classical test theory. In addition, the items in the final CM-NLS were tested for their validity and reliability amongst 462 middle school students.The construct validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).The internal consistency reliability and split-half reliability were evaluated using Cronbach’s alpha coefficients.Results: The finalised CM-NLS consisting of 52 items that were based on three primary indicators (functional, interactive and critical) and six sub-indicators (obtain, understand, apply, interact, medial literacy and critical skill) was developed and validated. EFA suggested six factors explaining 69.44% of the total variance (Kaiser–Meyer–Olkin test = 0.916, Bartlett’s test χ2 = 5854.037, P < 0.001). CFA showed that the model fit the data adequately, with χ2/df = 1.911, root mean square error of approximation = 0.063, goodness-of-fit index (GFI) = 0.822 and adjusted goodness of fit index (AGFI) = 0.790. The total CM-NLS Cronbach’s alpha values of internal consistency and split-half reliability were 0.849 and 0.521, respectively, with reasonable reliability.Conclusions: CM-NLS is a valid and reliable instrument to measure nutrition literacy amongst middle school students. It provides the scientific basis for the evaluation of the nutrition literacy level of middle school students in Chongqing and the implementation of nutrition education strategies.

Abstract Background Many frequently used instruments fail to assess psychosocial functioning in patients with bipolar disorder. The Functioning Assessment Short Test (FAST) was developed in order to tackle this problem and to assess the main functioning problems experienced by patients with bipolar disorder. However, the original FAST is not fully applicable in older adults due to the domain of occupational functioning. The aim of our study was to validate an adapted version for Older adults (FAST-O) in a group of older adults with bipolar disorder (OABD). Methods 88 patients aged 50 years and over diagnosed with bipolar disorder were included. We adapted the items in the area of “work-related functioning” of the FAST into items assessing “societal functioning”. Several measurements were conducted in order to analyse the psychometric qualities of the FAST-O (confirmatory factor analysis for internal structure, Cronbach’s alpha for internal consistency, Spearman’s rho for concurrent validity, Mann–Whitney U test for discriminant validity). Results Mean age in the study sample was 65.3 (SD = 7.5) and 57.3% was female. The internal structure was most similar to the internal structure of the original FAST. The internal consistency was excellent (Cronbach’s alpha = .93). The concurrent validity when correlated with the Social and Occupational Functioning Assessment Scale was low, but significant. The FAST-O was also able to distinguish between euthymic and symptomatic OABD patients. Conclusions The FAST-O has strong psychometric qualities. Based on our results, we can conclude that the FAST-O is a short, efficient solution in order to replace global rating scales or extensive test batteries in order to assess daily functioning of older psychiatric patients in a valid and reliable manner.

Patient-centredness in care is a core healthcare value and an effective healthcare delivery design requiring specific nurse competences. The aim of this study was to assess (1) the reliability, validity, and sensitivity of the Finnish version of the Patient-centred Care Competency (PCC) scale and (2) Finnish nurses’ self-assessed level of patient-centred care competency. The PCC was translated to Finnish (PCC-Fin) before data collection and analyses: descriptive statistics; Cronbach’s alpha coefficients; item analysis; exploratory and confirmatory factor analyses; inter-scale correlational analysis; and sensitivity. Cronbach’s alpha coefficients were acceptable, high for the total scale, and satisfactory for the four sub-scales. Item analysis supported the internal homogeneity of the items-to-total and inter-items within the sub-scales. Explorative factor analysis suggested a three-factor solution, but the confirmatory factor analysis confirmed the four-factor structure (Tucker–Lewis index (TLI) 0.92, goodness-of-fit index (GFI) 0.99, root mean square error of approximation (RMSEA) 0.065, standardized root mean square residual (SRMR) 0.045) with 61.2% explained variance. Analysis of the secondary data detected no differences in nurses’ self-evaluations of contextual competence, so the inter-scale correlations were high. The PCC-Fin was found to be a reliable and valid instrument for the measurement of nurses’ patient-centred care competence. Rasch model analysis would provide some further information about the item level functioning within the instrument.

Distress Scale

Abstract Background Studies of psychological distress in Sierra Leone have typically used measures which were developed for use in other contexts, and which often have not been adapted or validated for use in Sierra Leone. This has resulted in a lack of reliable information about the patterns of psychological distress within the population, which is a barrier to the development of effective and appropriate mental health services. The aim of the study was to develop a locally-appropriate measure of psychological distress for Sierra Leone. Methods The new measure consists of two instruments: the Sierra Leone Psychological Distress Scale (SLPDS) and a gendered measure of ability to carry out daily tasks—a Function scale—as an indication of the severity of distress. A three-phase mixed methods exploratory sequential study was conducted. Phase 1 was item generation and testing, leading to the development of a set of potential items for both instruments. Phase 2 was a small pilot study (N = 202) leading to the selection of the final set of items for both measures. Phase 3 was a validation phase where the SLPDS and the Function scale were administered with a larger sample of 904 respondents. Item analysis was used to assess the internal consistency of the scales, and Exploratory Factor Analysis to explore the properties of the SLPDS. Results Exploratory factor analysis using the principal axis factoring with an oblique rotation identified a three-factor structure for the 18-item SLPDS. Internal consistency for the SLPDS (Cronbach’s alpha = 0.89) and three subscales was good (Cronbach’s alpha > 0.73). The internal reliability of the male and female versions of the Function scale was also found to be acceptable (Cronbach’s alpha = 0.90 for the female scale and 0.79 for the male scale). Conclusions Together the SLPD and Function scales provide a locally-validated tool which will enable government bodies and local and international non-governmental organisations in Sierra Leone to assess mental health and psychosocial needs. This will support both effective service provision and the evaluation of initiatives designed to improve mental health and psychosocial wellbeing.

Knowledge Scale

Background: The incidence of dementia is increasing dramatically worldwide. It is important to determine knowledge about the dementia for it’s prevention, early diagnosis, treatment, and care. The psychometric properties of the Turkish version of the Dementia Knowledge Assessment Scale (DKAS-T) were evaluated in this study. Methods: The psychometric study was conducted. A total of 1592 participants were recruited between November 2019 and March 2020. The data were collected using a sociodemographic form and DKAS-T. The language and content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were used to assess the validity of the scale. The scale’s reliability was obtained using Cronbach’s alpha coefficient, a paired sample t-test, item-total score correlation, and Hotelling’s T-squared test. Results: The mean age of the sample was 29.38 (±11.50) years; 66.8% (n = 1064) were female, and 54.1% (n = 861) reported their income status as income equal to expenditure. The DKAS-T demonstrated content validity and adequate sensitivity (Kendall W = 0.155, p = 0.093). The scale consisted of seventeen items and was unidimensional, which explained 28.705% of the variance. All the factor loadings were found to be >0.30 in factor analysis. In CFA, all of the fit indexes were >0.95 and root mean square error of approximation (RMSEA) was 0.033. A Cronbach’s alpha value of 0.836 was obtained for the entire scale. It was determined that the scale has invariance according to time (t = −1.362, p = 0.181). Homogeneity of the scale was 3.26%, and there was no absence of reaction bias (Hotelling’s T-squared = 2573.681, p < 0.001). Conclusion: The results demonstrated that the instrument is reliable and generates valid data for the Turkish sample. This scale can be used to determine knowledge about dementia and planning educational interventions in the issue.

The study aimed to carry on the process of the cultural adaptation of the Italian Spine Youth Quality of Life Questionnaire (ISYQOL) into Polish (ISYQOL-PL). The a priori hypothesis was: the ISYQOL-PL questionnaire is reliable and appropriate for adolescents with a spinal deformity. Fifty-six adolescents (mean age 13.8 ± 1.9) with idiopathic scoliosis (AIS) with a mean Cobb angle 29.1 (±9.7) and two with Scheuermann juvenile kyphosis (SJK) with a kyphosis angle 67.5 (±17.7) degrees were enrolled. All patients had been wearing a corrective TLSO brace for an average duration of 2.3 (±1.8) years. The Institutional Review Board approved the study. The cross-cultural adaptation of the ISYQOL-PL was performed following the guidelines set up by the International Quality of Life Assessment Project. The reliability was assessed using internal consistency (the Cronbach’s alpha coefficient) and test–retest reliability (intraclass correlation coefficient ICC2.1, CI = 95%); moreover, floor and ceiling effects were calculated. The internal consistency was satisfactory (Cronbach’s alpha coefficient 0.8). The test–retest revealed high reliability with the value of ICC2.1 for the entire group 0.90, CI (0.84 to 0.94). There was neither floor nor ceiling effect for the ISYQOL-PL overall score. The ISYQOL-PL is reliable and can be used in adolescents with spinal deformity.

ABSTRACT Objective To carry out the preliminary stages of the cross-cultural adaptation of the Family Assessment Device (FAD) to Brazilian Portuguese language and examine its reliability. Methods The translation and cross-cultural adaptation of the FAD were developed according to the methods internationally recommended. The resulting product was applied to 80 individuals who completed the questionnaire on two different occasions, seven days apart. Internal consistency was obtained through Cronbach’s alpha, and reliability was estimated by using the Bland and Altman method. Results The internal consistency obtained was very good (Cronbach’s alpha = 0.910). The mean differences of FAD dimensions found in the Bland and Altman test were the following: -0.21 (Problem Solving); -0.32 (Communication); -0.17 (Roles); 0.2 (Affective Responsiveness); -0.27 (Affective Involvement); -0.08 (Behavior Control); -0.02 (General Functioning). Conclusion The processes of translation and cross-cultural adaptation were successful. Assessment of the structural validity and external construct validity is recommended for the improvement of the Brazilian version.
