BACKGROUND Parents need information about their children’s symptoms and the Internet is a major resource that may serve as a convenient repository of health information for parents. There is an urgent need for health professionals to provide parents with evidence-based child health websites. There is also a need for instruments to measure their accessibility, usability, usefulness and confidence building. OBJECTIVE The main aim of the present study was to develop a questionnaire for measuring users’ evaluation of different aspects of a Spanish paediatric Health web for parents. We further sought to evaluate the content validity and psychometric reliability of our instrument. METHODS After a review of the literature we designed an initial 40-qualitative item pilot survey, following the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) guidelines. We performed a content validation study by experts review and the survey was then administered via web. Psychometric analyses were used to establish scales through exploratory and confirmatory factor analyses. Reliability studies were performed using Cronbach's Alpha and Two-Split Half Method. RESULTS Content validation of the questionnaire by experts was considered as excellent. The pilot web survey was completed by 516 volunteer participants. Exploratory factor analysis allowed us to exclude 26 of the 40 initial items. Confirmatory factor analysis of the resultant 14-item questionnaire confirmed the five initial domains previously detected in the exploratory confirmatory analysis. The goodness of fit for the competing models was established through fit indices and confirmed the previously established domains. Adequate internal consistency was found for each of the subscales as well as the overall scale. CONCLUSIONS Effectiveness and reliability are essential aspects of eHealth interventions and should be properly evaluated. Although our research has limitations, we can assume that our questionnaire is appropriate for the evaluation of an eHealth Spanish paediatric web for parents.

There is a need for health professionals to provide parents with not only evidence-based child health websites but also instruments to evaluate them. The main aim of this research was to develop a questionnaire for measuring users’ evaluation of the usability, utility, confidence, the well-child section, and the accessibility of a Spanish pediatric eHealth website for parents. We further sought to evaluate the content validity and psychometric reliability of the instrument. A content validation study by expert review was performed, and the questionnaire was pilot tested. Psychometric analyses were used to establish scales through exploratory and confirmatory factor analyses. Reliability studies were performed using Cronbach’s alpha and two split-half methods. The content validation of the questionnaire by experts was considered as excellent. The pilot web survey was completed by 516 participants. The exploratory factor analysis excluded 27 of the 41 qualitative initial items. The confirmatory factor analysis of the resultant 14-item questionnaire confirmed the five initial domains detected in the exploratory confirmatory analysis. The goodness of fit for the competing models was established through fit indices and confirmed the previously established domains. Adequate internal consistency was found for each of the subscales as well as the overall scale.

The Worry Domains Questionnaire was proposed as a measure of both pathological and nonpathological worry, and assesses the frequency of worrying about five different domains: relationships, lack of confidence, aimless future, work, and financial. The present study analyzed the factor structure of the long and short forms of the WDQ (WDQ and WDQ-SF, respectively) through confirmatory factor analysis in a sample of 262 students (M age = 21.8; SD = 2.6; 86.3% females). While the goodness-of-fit indices did not provide support for the WDQ, good fit indices were found for the WDQ-SF. Furthermore, no source of misspecification was identified, thus, supporting the factorial validity of the WDQ-SF scale. Significant positive correlations between the WDQ-SF and its subscales with worry (PSWQ), anxiety (STAI-T), and depression (BDI) were found. The internal consistency was good for the total scale and for the subscales. This work provides support for the use of the WDQ-SF, and potential uses for research and clinical purposes are discussed.

This paper describes the development of a leadership questionnaire the aim of which is to assess the behaviours required to lead change and transformation, while at the same time managing organisational unit performance effectively. A Delphi technique was used to facilitate the identification and testing of emerging leadership dimensions and items, starting with a three-stage model of charismatic leadership, The resultant leadership model comprises four stages, measured as 21 dimensions. The research questionnaire consists of 235 items. The questionnaire was field tested by means of 360° assessment conducted amongst 189 unit managers from a diverse group of organisations. Seven hundred and fifty completed questionnaires were obtained. Unrestricted principal component analyses were performed on each of the sub-scales (dimensions) to examine the unidimensionality assumption. This procedure resulted in the formation of three additional sub-scales. Item analyses on each of the sub-scales produced highly satisfactory Cronbach Alpha values. Further confirmatory factor analyses using LISREL were conducted on each of the 24 sub-scales. A series of goodness-of-fit indices generally showed satisfactory results. Overall, results indicate that a 96-item questionnaire format consisting of 24 dimensions with four items each (selected on the basis of factor loadings) could be used with confidence. Recommendations are made for further research.

The presence of dysfunctional cognitions about how individuals see themselves and others is a hallmark of psychopathology. The Brief Core Schemas Scale (BCSS) was developed to evaluate adaptive and dysfunctional beliefs about the self and others. This study describes the first psychometric analysis of the BCSS in the Portuguese population. Participants were recruited from community ( N = 320, Mage=27.31, DP = 12.75). Confirmatory factor analysis (CFA) was used to confirm the BCSS factorial structure. Four-factor model revealed moderate to adequate goodness-of-fit indices (χ2/df = 717.1, (246) p = .01; SRMR = .044; RMSEA = .077; CFI/TLI < .90). Negative views of the self and others correlated positively with early maladaptive schemas, distress, and symptomatology and correlated negatively with psychological well-being. An inversed correlational pattern was found with the positive views of the self and others. Despite the model's moderate adherence to the data, results suggest that the BCSS may be an asset in the assessment of dysfunctional and adaptive cognitions about the self and others. Further analysis is required to deepen the psychometric properties of the BCSS in the Portuguese population.

Literatures in the field of psychometrics recommend researchers to employvarious of methods on measuring individual attributes. Ideally,each methods are complementary and measuresthe construct designed to be measured. However, some problems arise when among the methods is unique and unrelated to the construct being measured. The uniqueness of method can lead what is called the method effect. In testing construct validity using confirmatory factor analysis, the emergence of this effect tend to reducing the goodness of fit indices of the model. There are many ways to solve these problem, one of themis controling the method effects and accommodate it to the model. This paper introduces how to accommodate method effecton the confirmatory factor analysis using structural equation modeling. In the application section, author identify the emergence of method effects due to the differences item writing direction (favorable-unfavorable). The analysis showed that method effectemerge from different writing direction.

Abstract Background: The Salzburg Emotional Eating Scale (SEES) and the Emotional Eater Questionnaire (EEQ) are self-reported measures developed to evaluate emotional eating in adults in Western countries. To date, the psychometric properties of the SEES and the EEQ have not been studied among Iranian adults. The aim of the current study is to translate the SEES and the EEQ from English to Persian and examine the psychometric properties of the SEES and EEQ.Method: The sample of this study comprised of 489 Iranian adults who completed the SEES and the EEQ questionnaires online. Results: Findings of face, content, and construct validity tests confirmed that the SEES and the EEQ had acceptable validity and appropriate reliability. The results from confirmatory factor analysis showed acceptable goodness-of-fit indices for two measures. Conclusion: Results of Average Variance Extracted, Construct Reliability, and goodness-of-fit indices showed that the SEES was better for evaluating emotional eating among Iranian adults than the EEQ.

The purpose of this study was to adapt the &ldquo;Attitudes toward Physical Activity Scale&rdquo; (APAS) for Turkish higher education students. Study was conducted during 2018&ndash;2019 autumn semester at a public university in the central Anatolia region of Turkey. The APAS was applied to 1021 voluntary university students from eleven different faculties and departments of the university. Descriptive statistics, exploratory and confirmatory factor analyses, internal consistency coefficients were used in statistical analysis. Exploratory factor analysis revealed a six factor solution explaining 60.2% of the variance. Then, confirmatory factor analysis on the 38 items showed good fit to the 6-dimension model according to the goodness-of-fit criteria. The psychometric data of the scale showed that the Turkish version of the scale for higher education students reached the required levels. As a result, the &ldquo;Attitudes toward Physical Activity Scale&rdquo; can be used in reliable and valid way at higher education students in Turkey at national or cross-cultural studies in examining physical activity attitudes.

Background: Despite its popularity, the psychometric properties of the Extended Nursing Stress Scale (ENSS) in working adults are yet to be evaluated in different settings. Methods: This study examined the ENSS in acute care settings among licensed nurses through a questionnaire survey. The sample responses were examined using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results: A response rate of 37% was achieved; 199 licensed nurses completed the questionnaire. Workplace stress was found to have factorial structures similar to those in the previous studies that had different samples. In this sample, all subfactors had satisfactory coefficients ranged between .58 and .89. The goodness of fit indices met the usual criteria. The reliability ranged between .64 and .95. Conclusions: The ENSS showed a stable structure with reasonable internal consistency and construct validity.
