Objective: To examine aspects of the reliability and validity of the Reynolds Adolescent Depression Scale (RADS) in measuring depression in New Zealand adolescents of all major ethnic groups. Method: A sample of 9699 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey which included the RADS. Data from this survey have been used to assess some aspects of the reliability and validity of the RADS in the New Zealand context across different ethnic groups. Cronbach's alpha, itemtotal score correlations, correlation to other questions and a factor analysis were done in order to examine the internal reliability, content validity, convergent validity and construct validity of the data and compare to the original Reynolds validation study. Results: Tests of the scale resulted in scores over 0.90 on Cronbach's alpha and high itemtotal score correlations, with a median correlation of 0.62 and 25 of the 30 correlations measuring more than 0.5. The scores were found to have similar factor structure to the original scale and the correlations to other depression related questions indicate acceptable concurrent validity. Conclusions: On all of the tests conducted, the RADS was found to have acceptable reliability and validity for New Zealand adolescents across the major different ethnic groups, indicating that it is a valid and appropriate instrument to use with New Zealand adolescents.

Objective: The aim of the present study was to examine the reliability and validity of the short form of the Reynolds Adolescent Depression Scale (RADS-SF). Method: A sample of 9567 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey that included the full-length version of the RADS. The reliability and validity of the subset of items that make up the RADS-SF and its comparability to the original version were assessed using Cronbach's alpha, kappa statistics, correlations between the two versions of the instrument, confirmatory factor analysis and correlation to other questions in the survey considered likely to be associated with depression. Results: The RADS-SF had Cronbach's alpha of 0.88, was strongly correlated (0.95) to the RADS, had acceptable fit for the data (χ2=2823.27, df=35, comparative fit index=0.96, root mean square error of approximation=0.092, 90% confidence interval=0.089–0.095, standardized root mean square residual=0.042), showed configural invariance across gender, age and ethnic groups, and was strongly correlated with other depression-related questions, such as suicidal ideation (r=0.48). While the overall agreement for classification of depression by the two scores was good (κ=0.75), a higher percentage of students were classified as having depressive symptoms using the recommended RADS-SF cut-off point of 26 compared with the RADS criteria. Conclusions: The RADS-SF was found to have acceptable reliability and validity and to have psychometric properties comparable to the RADS in a large population of New Zealand adolescents.

Background: Infertility is a public health problem and can lead to depressive symptoms. In recent years, the WHO-five Well-being Index (WHO-5) has been used as a screening measure for depression, but study on psychometric properties in people with infertility is scarce. The objective of this study was to examine the reliability and validity of the Persian version of the WHO-5 in people with infertility. Methods: Overall, 539 infertile patients from a referral infertility center in Tehran, Iran in the period between May and Aug 2017, completed the WHO-5, along with other psychological measures: the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). Construct validity and internal consistency of WHO-5 were evaluated using confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with PHQ-9 and HADS. Results: The prevalence of poor well-being was 44.3% and that of depression was 18.6%. CFA confirmed the unidimensional factor structure of the WHO-5. Internal consistency of the WHO-5 was good (Cronbach’s alpha=0.858). The WHO-5 significantly correlated with the PHQ-9 (r=-0.522), HADS-anxiety (r=-0.524) and HADS-depression (r=-0.630), confirming convergent validity. Conclusion: The WHO-5 is a short and easy to use questionnaire with satisfactory reliability and validity that appears suitable for use as a screening test for depressive symptom in infertile people. In addition, the prevalence of depression and poor well-being was very high in this population.

Abstract Background: Parents of children with autism spectrum disorder (ASD) are known to poorer quality of life. The Quality of Life in Autism Questionnaire (QoLA) is a commonly used instrument for measuring the quality of life in parents of children with ASD. The aim of this study was to evaluate the reliability and validity of the QoLA in Iranian mothers of children with ASD.Methods: The sample of this methodological study consisted of 88 mothers of children with ASD in Arak, Iran. The data were collected using convenience sampling method between September 2019 and January 2020. A battery of questionnaires was administered to mothers which included the QoLA, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Perceived Stress Scale-4 (PSS-4). Factor structure and internal consistency of the QoLA were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with WHOQOL-BREF, PHQ-9, GAD-7 and PSS-4.Results: The mean total scores of QoLA Part A and Part B were 86.50 (SD=13.89) and 61.41 (SD=18.21), respectively. Both subscales exhibited good internal validity (with Cronbach’s alpha of 0.899 and 0.950 for Part A and Part B, respectively). The convergent validity of both subscales of QoLA was proved via moderate to strong correlations with measure of the WHOQOL-BREF. In addition, both QoLA Part A and Part B scores were negatively correlated with measures of PHQ-9, GAD-7, and PSS-4. The confirmatory factor analyses provided evidence for unidimensionality of both subscales of QoLA.Conclusion: The Persian version of QoLA displays satisfactory reliability and validity in Iranian mothers of children with ASD.

Abstract Background The Harris Hip Score (HHS) is a widely used Patient-Related Outcomes score. It measures pain and function levels in patients with hip pathologies. Objectives The main objective of this study is to translate and culturally adapt the HHS into Arabic, and to further assess the reliability and validity of translated version Material & Methods 110 patients participated in this survey. The internal consistency tests were performed using Cronbach’s alpha. Test-retest reliability (intra-correlation coefficient), convergent construct validity, convergent validity, floor & ceiling effects and responsiveness was also calculated. In order to measure the level of agreement, Bland-Altman Plot, forest Plots are performed. Results Test reliability for the first testing situation - calculated using Cronbach's alpha - was 0.98 for the pain subscale, 0.98 for the stiffness, and 0.99 for the physical function subscale. For the second testing, reliability was 0.99, 0.97, and 0.99 (pain, stiffness, and physical function, respectively). This only proves that WOMAC is an instrument with good reliability. Same calculation of Cronbach’s alpha was essential to testing the reliability of the Harris Hip Score. For each of the three testing occasions the reliability was very good or excellent – α 1 = 0.92, α 2 = 0.91, and α 3 = 0.90. Intra-class correlation coefficient was good with the score of 0.76 (95% CI 0.44-0.88). Conclusion Overall, Arabic version of HOOS could be used as diagnostic tool for patients with hip problems, when it comes to information about the overall condition of the patient, especially about the improvement or deterioration, however, it is important to be cautious using HHS when the change magnitude of patient’s condition is investigated, since there is a potential probability that the level of improvement of the patient’s condition will be overestimated by HHS.

Motivation To Participate

This study aims to investigate the relationship between aggression and sports participation motives of Sports High School students in Adıyaman, Kahramanmaraş, and Malatya provinces in Turkey. 575 Sports High School students, including 385 males and 190 females, participated in our research. Surveys used to measure variables included a 30-item sports participation motivation scale a 30-item “aggression inventory”. Reliability and validity studies of the sport participation motive scale were done by Gill et al, and it was determined that Cronbach's alpha coefficients were between 0.30 and 0.78 for the sub-dimensions. The Cronbach's alpha internal consistency coefficient of the aggression scale was calculated as .83. According to our findings, there was a moderately positive relationship between assertiveness, which is the sub-dimension of aggression, and competition, and friends, which is the sub-dimension of the motivation to participate in sports. A moderately significant negative correlation was found with the sub-dimensions of aggression and entertainment, which is the sub-dimension of the motivation to participate in sports. A moderately significant positive relationship was found with destructive aggression, which is the sub-dimensions of aggression, and success and status, and competition, which are the sub-dimensions of participation in sports.

Simulation Evaluation

Background and objective: Globally, the use of clinical simulation has been incorporated in different nursing programs. It is important to evaluate simulation using reliable and valid instruments. Using the same instrument helps to evaluate simulation under the same criteria both nationally and internationally. The National League of Nursing developed three simulation scales which is widely used in different countries and demonstrates a good reliability and validity. Nevertheless, it is only available in English. The aim of the study was to translate the original NLN simulation evaluation scales into Traditional Chinese and evaluate its psychometric properties.Methods: Beaton and colleague’s (2000) cross-cultural adaptation guidelines was adopted. Cronbach’s alpha coefficient (α) and Corrected item-total correlation was used to determine the internal reliability. Haccoun’s single group technique was used to assess the equivalent of the scale in the original and the translated version. Lastly, Exploratory Factor Analysis (EFA) was used to determine the factor structure and Intra-Class Correlation Coefficient (ICC) to test the stability of translated scale.Results: Nine simulation experts from Hong Kong, Mainland China, Singapore and Taiwan confirmed translation of the NLN scales (EPQ-C, SDS-C, SSCL-C). Cronbach’s alpha of all subscales and overall scales were acceptable (0.72-0.89). The intra-language, inter-language and temporal inter-language cross correlations between the original and translated scales were correlated (p < 0.01). ICC of the translated scales ranges from good to excellent (0.78-0.91). Lastly, EFA also demonstrated the items were theoretically coherent (≥ 0.40) and have the same factor structure as the original English version.Conclusions: Traditional Chinese NLN simulation evaluation scales demonstrated strong validity and reliability.

Abstract Background Patient enablement is a core tenet of patient-centred and holistic primary care. The Patient Enablement Instrument (PEI) is a transitional measure limited in its ability to measure changes over time. A modified version, PEI-2, has been developed to measure enablement at a given time-point without comparison to a recalled baseline. Objective To assess the validity, reliability, sensitivity and responsiveness of PEI-2. Methods PEI-2 was modified from the Chinese PEI to assess enablement over 4 weeks in a prospective cohort study nested within a community support programme [Trekkers Family Enhancement Scheme (TFES)] in Hong Kong. Construct validity was assessed by factor analysis and convergent validity by Spearman’s correlations with health-related quality of life and depressive symptoms. Internal reliability was assessed using Cronbach’s alpha. Test–retest reliability was assessed by intraclass correlation (ICC), responsiveness by 12–24-month change in PEI-2 score and sensitivity by differences in change of PEI-2 score between TFES participants and a control group. Results PEI-2 demonstrated construct validity with all items loading on one factor (factor loadings &gt;0.7). Convergent validity was confirmed by significant correlations with 12-item Short Form Questionnaire, version 2 (r = 0.1089–0.1919) and Patient Health Questionnaire-9 (r = −0.2030). Internal reliability was high (Cronbach’s alpha = 0.9095) and test–retest reliability moderate (ICC = 0.520, P = 0.506). Significant improvements in PEI-2 scores among the TFES group suggested good responsiveness (P &lt; 0.001). The difference in change of PEI-2 scores between TFES and control was significant (P = 0.008), indicating good sensitivity. Conclusions This study supports the validity, reliability, sensitivity and responsiveness of PEI-2 in measuring changes in enablement, making it a promising tool for evaluating enablement in cohort and intervention studies.

Background and Purpose: Globally, depressive symptoms are a leading contributor to years lived with disability. The Center for Epidemiological Studies–Depression (CES-D) scale has been used extensively to quantify depression; yet, its psychometric properties remain contentious. This study examined the reliability and factor structure of the CES-D in the MacArthur Foundation’s Midlife in the United States Study (MIDUS), a nationally representative cohort study of noninstitutionalized, English-speaking adults aged 24–74 years. Methods: Internal consistency (Cronbach’s alpha) and confirmatory factor analysis (CFA) were used to examine the reliability and factor structure of the CES-D. Results: There were 1,233 participants who were included in the analysis (mean age = 57.3 years [SD = 11.5], 56.7% female). Cronbach’s alpha of .90 was observed. The 4-factor model had the best model fit. Conclusions: High internal consistency was demonstrated alongside a replication of the original 4-factor structure. Continued use of the CES-D in noninstitutionalized populations is warranted.

Nurses Perceptions

Every year approximately 4 million women in the United States experience childbirth. This event has been cited as pivotal in a woman’s life. Labor support is an important part of this experience since it influences the woman’s classification of the birth experience as positive or negative. Therefore, understanding how intrapartum nurses perceive the role of supportive care during labor is paramount. The purpose of this study was to develop a reliable and valid instrument that measures intrapartum nurses’ perceptions concerning the importance of professional labor support in their practice. The sample included 146 intrapartum nurses from Texas. Cronbach’s alpha, Pearson’s r, and descriptive statistics were used for data analysis. Cronbach’s alpha for the Labor Support Questionnaire (LSQ) was 0.90. Convergent validity with the Caring Behavior Inventory was .57 (p < .001). Findings indicated beginning support for the reliability and validity of the LSQ. Further development and psychometric testing is recommended to ascertain the dimensionality of the LSQ.
