A Patient-Reported Outcome (PRO) measure titled Cuestionario para la Evaluación de la Adhesión al Tratamiento Antiretroviral (acronym CEAT-VIH) is currently available in paper-and-pencil and digital (online assessment) formats. Due to the advantages of online assessment, the main objective of this work was to evaluate psychometric properties of the online version, in an international sample, to accumulate evidence of its validity and provide score norms for the questionnaire. A psychometric study was performed with an international sample of 1,470 participants, from 30 countries, to accumulate evidence of CEAT-VIH validity regarding internal structure and related external criterion (e.g., viral load, number of pills, and AIDS-related symptoms). Descriptive statistics and normative data for scores are also presented. The majority of participants were men (72.4%), aged 15 to 78 years old ( M = 39.3, SD = 12.6). A unidimensional model with five facets occurred as the observed variables converged, which presented a good model fit (comparative fit index [CFI] = 1.000; Tucker–Lewis index [TLI] = 0.999; standardized root mean square residual [SRMR] = 0.027; and root mean square error of approximation [RMSEA] [90% confidence interval, CI] = 0.009 [0.000, 0.038], p = .995). There was a weak invariance for the CEAT-VIH structure for language versions and countries. Cronbach’s alpha values for the instrument (17 items) were acceptable across language versions (.88-.96). Evidence of validity related to external criteria was achieved by associations (e.g., Spearman and Mann–Whitney) between CEAT-VIH scores and relevant clinical (e.g., CD4+ cells, viral load, number of pills, and AIDS-related symptoms) and sociodemographic (e.g., gender, age, employment status, education level, place of residence, and participation at local AIDS association) variables. In conclusion, the overall data on the evaluated psychometric properties allow recommendation of the use of this instrument in research and applied settings.

The posthumous organ donation reasoned action scale (PODRAS) may be the first multidimensional scale measuring individuals’ perceptions, which is developed based on the Theory of Reasoned Action and guided by empirical data. This study moves further to validate the scale and examine its psychometric properties. Two hundred and twenty-one university students participated in the study. Results suggested that the scale has a structure with six dimensions: Mutilation and Imperfectness, Legacy for Family, Altruism, Detachment, Eradication of Hope, and Burden on Family. The scale was evaluated with acceptable to good psychometric properties and model fit (χ2/ df = 1.58; root mean square error of approximation = .07; standardized root mean square residual = .08; comparative fit index = .92; incremental fit index = .92; Tucker–Lewis index = .90). Construct validity was also supported. The study has significant contributions that theoretically, the scale proposed a conceptualization framework in understanding posthumous organ donation, whereas methodologically, the scale serves as a tool that facilitates future studies of organ donation behaviors.

Abstract Pakistani migrants are one of the fastest-growing communities in Australia, and the majority speak Urdu at home. There is a lack of information regarding the health literacy of this population. This study aimed to translate the Health Literacy Questionnaire (HLQ) into Urdu and to explore its psychometric properties. A structured standardized procedure was followed to translate and validate HLQ into Urdu. Data were collected from 202 Pakistani migrants residing in Australia. The HLQ-Urdu was well understood by the respondents. The structural properties of HLQ-Urdu were close to the original HLQ. Data for all HLQ scales met pre-specified criteria for fit in the one-factor CFA model. The composite reliability was high, ranging from 0.84 to 0.91. A strict nine-factor CFA model was also fitted to the data with no cross-loadings or correlated residuals allowed, which showed excellent model fit statistics [χ2WLSMV = 1266.022 (df = 866, p = 0.000), comparative fit index  = 0.995, Tucker–Lewis index = 0.994, root mean square error of approximation = 0.050 and standardized root mean square residual = 0.069]. The Urdu version of HLQ showed robust psychometric properties. This HLQ-Urdu tool is now ready to be used to assess health literacy in Pakistani migrants in Australia. Availability of health literacy tools in migrant languages may help healthcare providers better understand the health literacy needs of migrant communities.

The purpose of this study was to examine the psychometric properties of Peabody Developmental Motor Scales II (PDMS-2-Folio and Fewell, 2000) using a Portuguese sample. The validation of the Portuguese version of the PDMS-2 was applied according to the manual, for 392 children, from two institutions, from 12 to 48 months, with an analysis of the internal consistency (α Cronbach), of test–retest reliability (ICC) and construct validity (confirmatory factor analysis). The results of the confirmatory factorial analysis (χ2 = 55.614; df = 4; p = 0.06; χ2/df =13.904; SRMR (Standardized Root Mean Square Residual) = 0.065; CFI (Comparative Fit Index) = 0.99, TLI = 0.99, RMSEA (Root Mean Square Error of Approximation) = 0.068) of two factors (Gross Motor and Fine Motor) as the original version but correlated. Most of the subtests had good internal consistency (α = 0.85) and good test–retest stability (ICC = 0.98 to 0.99). The results indicated that the Portuguese version of the PDMS-2 is adequate and valid for assessing global and fine motor skills in children aged 12 to 48 months, and can be used as a reference tool by health and education professionals to assess motor skills and, thus, allowing to detect maladjustments, deficiencies or precocity, so that children can later receive appropriate intervention.

Abstract Background The Catquest-9SF questionnaire is a patient reported outcome measure that quantifies the visual benefits from cataract surgery. The purpose of this study was to translate and adapt the Catquest-9SF questionnaire for France, to assess its psychometric properties via Rasch analysis, and to assess its validity when completed using an electronic notepad. Methods The Catquest-9SF questionnaire was translated following the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. Catquest-9SF and clinical data were collected from patients before and after routine cataract surgery. All questionnaire data were collected via an electronic notepad. Rasch analysis was performed to assess psychometric properties, and sensitivity to change was analysed for patients with complete paired pre- and post-operative questionnaires. Results A complete filled-in preoperative questionnaire was obtained for 848 patients. Rasch analysis showed good precision (person separation: 2.32, person reliability: 0.84), ordered category probability curves, no item misfit, and unidimensionality. The respondents were slightly more able than the level of item difficulty (targeting: −1.12 logits). Sensitivity was analysed on 211 paired questionnaires, and the postoperative questionnaires showed a clear ceiling effect. The effect size was 2.6. The use of an electronic notepad for completing the questionnaire worked out very well after some adjustments. Conclusions The French version of Catquest-9SF has good psychometric properties and is suitable for use in French-speaking patients. The use of the Catquest-9SF questionnaire in an electronic format showed good validity.

Abstract Objectives To develop and examine the psychometric properties of the Caring Behaviors Assessment Tool Nursing Version-Short Form (CBAN-SF) based on the Theory of Human Caring to assess the nurses’ perceptions about caring behaviors. Design This study is based on the Consensus-based Standards for the Selection of Health Measurement Instruments checklist. Setting The study was conducted at the medical-surgical services of Akdeniz University Hospital between October 2019 and January 2020. Participants This study was conducted with 216 nurses working in the surgery and internal clinics. Main Outcome Measures Psychometric properties of the Turkish version of the CBAN-SF with 27 items. Results It was found that the Content Validity Index (CVI) for the items of the draft scale was between 0.972 and 1.00 and the instrument’s CVI had an average score of 0.994. The CBAN-SF had good fit indexes (chi-square goodness of fit / degrees of freedom = 2.914, root mean square error of approximation = 0.075, comparative fit index = 0.984, non-normed fit index = 0.983, normed fit index = 0.972 and standardized root mean square residuals = 0.054) in structural validity. For internal consistency, the Cronbach’s alpha, Spearman–Brown and the Guttman split-half coefficients were all 0.974. The Cronbach’s alpha coefficient for the seven subfactors of the scale ranged between 0.793 and 0.904 and had acceptable internal consistency. The item-total score correlation of the scale was 0.648–0.829, and the factor loadings were 0.455–0.769. Conclusion The structural validity, internal consistency and content validity of the CBAN-SF supported to be a reliable and valid tool for assessment of caring behaviors by nurses.

The aims of this study were to validate an instrument that measured statistics anxiety and to examine how attitudes toward statistics predict statistics anxiety using the Attitudes Toward Statistics (ATS) Scale for a sample of 323 undergraduate social science majors enrolled in colleges and universities in the United States. A confirmatory factor analysis suggested retaining a revised two-factor model of the Statistical Anxiety Scale (SAS) to measure statistics anxiety, namely, help and interpretation anxiety ([Formula: see text] = 49.37, df = 38.13, p = .105, comparative fit index [CFI] = .959, standardized root mean square residual [SRMR] = .035, root mean square error of approximation [RMSEA] = .076). An examination of discriminant validity of the scores of the SAS with scores of the ATS subscales revealed that statistics anxiety and attitudes toward statistics are distinct constructs. Structural equational modeling was used to determine whether attitude toward course and attitude toward field were predictors of examination anxiety and asking for help anxiety. Of the two factors of the ATS scale, attitudes toward field and attitudes toward course, the latter predicted examination anxiety better than the former did, although both were moderate predictors of examination anxiety. We recommend that statistics educators consider the role of statistics anxiety as well as attitudes toward statistics and the field when designing their pedagogical approach.

<p><em>The purpose of this study is to identify factors (brand elements) that mediate between Millennials and brand loyalty, and to test a theoretical model that includes these mediating factors in describing the relationship between millennials and brand loyalty. The study focused on the key factors that we identified and hypothesized to mediate the relationship between millennials and brand loyalty. The quantitative study surveyed two hundred and fifty-three (n=253) respondents randomly drawn. Structural Equation Modelling (SEM) was used to test a model of the relationship between the mediating factors, millennials and brand loyalty. All model fit parameters were well within acceptable bounds. The Comparative Fit Index (CFI) was 0.999, Root Mean Square Error of Approximation (RMSEA) was 0.018, and Standardized Root Mean Square Residual (SRMR) was 0.022. However, we believe that the model is over-fitting the data, and this is not surprising given that there are 22 variables and 253 data points. These results show promise, but require further investigation in a second phase of the inquiry. This study limited itself to surveying millennials, brand loyalty, and the seven mediating factors we identified and hypothesized to play a role in mediating between them. Based on this study, brand management strategies are proposed.</em><em></em></p>

The process of assessing executive functions through behavioral observation scales is still under theoretical and empirical construction. This article reports on the analysis of the factorial structure of the EOCL-1 scale that assesses executive functions, as proposed by the theory developed by Luria, which has not been previously considered in this type of evaluation. In this scale, the executive functions taken into account are error correction, internal behavioral and cognition regulatory language, limbic system conscious regulation, decision making, future consideration of consequences of actions, goal-directed behavior, inhibitory control of automatic responses, creation of new behavioral repertoires, and cognitive–behavioral activity verification. A variety of validity and reliability analyses were carried out, with the following results: (a) an adequate internal consistency level of executive functions between α = 0.70 and α = 0.83, (b) significant convergent validity with a scale that assesses frontal deficits between r = −0.07 and r = 0.28, and (c) the scale’s construct validity that proposes a model with an executive central factor comparative fit index (CFI) = 0.93, root mean square error of approximation (RMSEA) = 0.04 (LO.04 and HI.04), standardized root mean square residual (SRMR) = 0.04, and x2(312) = 789.29, p = 0.001. The findings are discussed based on previous literature reports and in terms of the benefits of using a scale to assess the proposed executive functions.
