Background: The Clinical Learning Environment, Supervision and Nurse Teacher scale is a reliable and valid instrument to evaluate the quality of the clinical learning process in international nursing education contexts. Objectives: This paper reports the development and psychometric testing of the Spanish version of the Clinical Learning Environment, Supervision and Nurse Teacher scale. Design: Cross-sectional validation study of the scale. Setting: 10 public and private hospitals in the Alicante area, and the Faculty of Health Sciences (University of Alicante, Spain). Participants: 370 student nurses on clinical placement (January 2011--March 2012). Methods: The Clinical Learning Environment, Supervision and Nurse Teacher scale was translated using the modified direct translation method. Statistical analyses were performed using PASW Statistics 18 and AMOS 18.0.0 software. A multivariate analysis was conducted in order to assess construct validity. Cronbach's alpha coefficient was used to evaluate instrument reliability. Results: An exploratory factorial analysis identified the five dimensions from the original version, and explained 66.4% of the variance. Confirmatory factor analysis supported the factor structure of the Spanish version of the instrument. Cronbach's alpha coefficient for the scale was .95, ranging from .80 to .97 for the subscales. Conclusion: This version of the Clinical Learning Environment, Supervision and Nurse Teacher scale instrument showed acceptable psychometric properties for use as an assessment scale in Spanish-speaking countries.

Abstract: Aims: This paper is aimed to develop and validate the hypertension scale of the system of Quality of Life Instruments for Chronic Diseases, QLICD-HY. Methods: The QLICD-HY instrument was developed based on programmed decision procedures with multiple nominal and focus group discussions and pilot testing. A total of 157 inpatients with hypertension were used to provide the data measuring QOL three times before and after treatment. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness employing correlation and factor analyses, and t-tests. Results: Correlation and factor analyses confirmed good construct validity and criterion-related validity when using Short Form (36) Health Survey (SF-36) as a criterion. Test–retest reliability coefficients (Pearson r and intra-class correlation (ICC)) for the overall instrument score and all domains except for the hypertension-specific domain (SPD) (0.75) were higher than 0.80 with a range of 0.75–0.91; the internal consistency α for all domains except for the hypertension-specific domain (0.66) was higher than 0.70. The overall score and scores for most facets within each domain except for the social domain (SOD) had statistically significant changes (t-tests) after treatment with moderate effect sizes. Conclusion: QLICD-HY has good validity, reliability, responsiveness and can be used as the quality-of-life instrument for patients with hypertension. [Copyright &y& Elsevier]

Abstract: Background: The Perceived Stress Scale has been designed to measure the degree to which situations in a person''s life are perceived as stressful. Objective: The paper describes the development of an Arabic version of the Perceived Stress Scale. Design: A translation process with cross-cultural considerations was employed to produce an Arabic version of the Perceived Stress Scale. Settings: Participants were asked to complete the Arabic version Perceived Stress Scale twice in their homes. Participants: The Jordanian study population for the Arabic version Perceived Stress Scale validation consisted of 126 volunteers (74 male, 52 female). Ninety participants completed the scale twice (55 male, 35 female), of whom 58 were high schools teachers and 32 technical workers. Arabic was the first language of all participants and all gave informed consent. Results: The Arabic version Perceived Stress Scale reliability and validity were evaluated. Prior to an exploratory factor analysis, the suitability of data for factor analysis was assessed with acceptable results. The exploratory factor analysis showed two factors with eigenvalues greater than 1.0 (45.0% of variance). The Cronbach''s alpha coefficients were 0.74 (Factor 1), 0.77 (Factor 2) and 0.80 for the Arabic version Perceived Stress Scale overall. The test–retest reliability had an intra-correlation coefficient of 0.90. Conclusions: The Arabic version Perceived Stress Scale showed an adequate reliability and validity. Therefore, the Arabic Perceived Stress Scale is considered a suitable instrument to assess perceived stress in Arabic people. [Copyright &y& Elsevier]

Abstract: Aim: This paper describes the development and validation of the Revised Perioperative Competence Scale (PPCS-R). Background: There is a lack of a psychometrically tested sound self-assessment tools to measure nurses’ perceived competence in the operating room. Methods: Content validity was established by a panel of international experts and the original 98-item scale was pilot tested with 345 nurses in Queensland, Australia. Following the removal of several items, a national sample that included all 3209 nurses who were members of the Australian College of Operating Room Nurses was surveyed using the 94-item version. Psychometric testing assessed content validity using exploratory factor analysis, internal consistency using Cronbach''s alpha, and construct validity using the “known groups” technique. During item reduction, several preliminary factor analyses were performed on two random halves of the sample (n =550). Results: Usable data for psychometric assessment were obtained from 1122 nurses. The original 94-item scale was reduced to 40 items. The final factor analysis using the entire sample resulted in a 40 item six-factor solution. Cronbach''s alpha for the 40-item scale was .96. Construct validation demonstrated significant differences (p <.0001) in perceived competence scores relative to years of operating room experience and receipt of specialty education. Conclusions: On the basis of these results, the psychometric properties of the PPCS-R were considered encouraging. Further testing of the tool in different samples of operating room nurses is necessary to enable cross-cultural comparisons. [Copyright &y& Elsevier]

• Anxiety mediates the association between self-esteem and addictive smartphone use. • Self-esteem is negatively associated with anxiety. • Anxiety is positively associated with addictive smartphone use. • Self-control moderates the association between self-esteem and anxiety. Existing research supports an association between self-esteem and addictive smartphone use, yet the underlying mechanism is not clear. Building on the compensatory internet use model, the current study explored the possible mediator role of anxiety and moderator role of self-control in the link between self-esteem and addictive smartphone use. Two middle schools and two elementary schools in a metropolitan city in China were selected through convenient sampling. Eleven hundred and twelve adolescents from those schools completed a paper-and-pencil survey, which included measurements of self-esteem, addictive smartphone use, anxiety, and self-control. The relationships among variables were analyzed using a moderated mediation model in an SPSS macro named PROCESS. The moderated mediation model achieved satisfactory effect size, R2 = 28.65%; Specifically, (1) anxiety fully mediated the association between self-esteem and addictive smartphone use, CI = [−0.1, −0.05]: Self-esteem was negatively related to anxiety, which in turn was positively related to addictive smartphone use; (2) moderated mediation analysis results showed that high self-control enhanced the protective effect of self-esteem against anxiety. High self-esteem in adolescents is related to relatively low anxiety, which is related to less addictive smartphone use. Moreover, the protective effect of self-esteem against anxiety was enhanced by high self-control, suggesting that increasing self-esteem alone would not prevent addictive smartphone use in all adolescents.
