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]

• 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.
