Article Development and Preliminary Psychometric Properties of the Adolescent Sleep Health Belief Scale(Istanbul University-Cerrahpasa, Florence Nightingale Faculty of Nursing, 2025) Dikici H.; Kadıoğlu H.; Dikici, Hasret; Kadıoğlu, HasibeAIM: This study aimed to develop a scale based on the Health Belief Model that can reliably and validly evaluate adolescents’ beliefs toward sleep. METHODS: This study was conducted using a methodological design with 494 adolescents between September and October 2022 in Antalya, Türkiye . Eighty-one items about sleep were created according to the Health Belief Model. Validity was assessed in terms of content and construct validity, and reliability was assessed through internal consistency. Content validity was evaluated by ten expert opinions. The scale was tested for construct validity with exploratory factor analysis, after which the scale’s reliability was evaluated by examining item-total correlations using Pearson’s correlation analysis and assessing internal consistency with Cronbach’s Alpha. RESULTS: Item-level content validity index scores ranged between 0.80 and 1. The scale-level content validity index value was found to be 0.94. In the exploratory factor analysis of the 46-item scale, six factors were found with an eigenvalue greater than 1, explaining 57.7% of the total variance. The scale’s itemtotal correlations ranged from 0.26 to 0.79. Cronbach’s alpha coefficients for the subscales were 0.92 for perceived susceptibility, 0.90 for perceived severity, 0.90 for perceived benefits, 0.81 for self-efficacy, 0.79 for motivation, and 0.69 for perceived barriers. CONCLUSION: The Adolescent Sleep Health Belief Scale demonstrated good validity and reliability in adolescents. Its cross-cultural adaptation for use with adolescents in other countries is recommended. © 2025, Istanbul University-Cerrahpasa, Florence Nightingale Faculty of Nursing.

We aimed to evaluate and compare RME in subjects with OHS and a control group using an incremental load test and compare the RME of subjects with OHS in whom noninvasive ventilation (NIV) was and was not used. METHODS: Forty subjects with OHS (divided according to body mass index [BMI] as group I: 30-40 kg/m(2); and group II: 6 40 kg/m(2)) and 20 subjects with obesity (control group: 30-40 kg/m(2)) were included in the study. RME was evaluated using the incremental load test, and respiratory muscle strength (RMS) was evaluated using mouth pressure measurements. The 6-min walk test, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), EQ-5D Health-Related Quality of Life Questionnaire (EQ-5D), and the Obesity and Weight-Loss Quality of Life Instrument (OWLQOL) were performed. RESULTS: RME and RMS (%) in group I were lower than the control group (P=.001, P=.005, and P=.001, respectively). No significant difference was found between the 3 groups in terms of 6-min walk distance (6MWD) percentage predicted values (P=.98). RME in the NIV user group was higher than the non-user group (P 5.006). ESS, total PSQI, and FSS scores in the control group were less than group I (P=.01, P=.009, and P=.005, respectively) and group II (P 5.01, P <.001, and P <.001, respectively). The EQ-5D scores of the control group were higher than group II only (P=.005 and P=.005, respectively). There were no differences in OWLQOL between the groups (P=.053). CONCLUSIONS: RME was low in subjects with OHS but higher in those who used NIV. The incremental load test could be performed easily and safely in a clinic setting.
