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.

This study aimed to investigate the correlation between diet quality, cognitive function, sleep quality, and levels of coronaphobia in individuals aged 65 and above, to understand the impact of COVID-19. Materials and Methods: Sleep quality, diet quality, coronaphobia, and cognitive status of 72 older individuals were evaluated using the Pittsburgh sleep quality index, healthy eating index 2010, Montreal cognitive assessment scale, and coronavirus-19 phobia scale, respectively. Results: The participants had poor diet quality (54.2%), poor sleep quality (62.5%), obesity (41.7%), higher levels of coronaphobia, and cognitive impairment. There was a moderate negative relationship between sleep quality and coronaphobia and between cognitive status and coronaphobia (p <= 0.00); and a weak positive relationship between diet quality and cognitive status (p<0.05). However, no relationship was found between sleep quality and diet quality, and between coronaphobia and diet quality (p>0.05). Conclusion: Our study highlights the significant challenges faced by older adults during the COVID-19 pandemic, including poor nutrition quality, sleep disturbances, coronaphobia, and cognitive impairment. Our findings suggest a potential interplay between nutrition quality, sleep patterns, and cognitive function among older adults, with those experiencing coronaphobia exhibiting additional cognitive and sleep-related concerns. We advocate the implementation of targeted interventions aimed at mitigating cognitive impairment, addressing nutritional deficiencies, and improving sleep quality among older adults, irrespective of COVID-19 infection status, to enhance overall well-being during these challenging times.Article Citation - WoS: 9Citation - Scopus: 7RELATIONSHIP OF DAILY TIME SPENT OUTDOORS WITH SLEEP QUALITY AND EMOTIONAL WELL-BEING AMONG COMMUNITY-DWELLING OLDER ADULTS DURING COVID-19 RESTRICTIONS(Gunes Kitabevi Ltd Sti, 2021) Sansal, Kenan Eren; Balci, Leyla Atas; Cinar, Fadime; Coskunsu, Dilber Karagozoglu; Tanriover, Sezin Hatice; Uluengin, Mehmet BenguIntroduction: Given the recent constraints imposed due to the ongoing COVID-19 pandemic and the importance of the daily light-dark cycle for entraining the human circadian system, it is possible to state that the elderly are likely to be at serious risk of experiencing sleep-related problems. Whilst reduced or limited time outdoors, and thus, exposure to diurnal bright light appear to be detrimental to sleep and emotional well-being in old age, further research is required to confirm this relationship. Materials and Method: To build on earlier work, a two-week study was conducted in a sample of 79 community-dwelling older adults recruited by using snowball sampling method. Throughout the study, the participants were allowed to be outdoors from 10.00 a.m. to 1.00 p.m. on weekdays. Whilst the participants were performing their daily habitual activities, they were asked to keep an activity diary and report on their sleep quality and emotional wellbeing using two questionnaires. Results: The results demonstrated that participants' daily time spent outdoors (49.13 minutes on average) positively correlated with their perceived sleep quality and emotional well-being at various - but significant - levels (p<0.05). Moreover, significant negative correlations were identified between participants' sleep quality and experienced emotional disturbances (p<0.001). Conclusion: Based on the research findings, it is reasonable to conclude that spending momentary periods outdoors may have adverse consequences for the elderly. To maintain a healthy sleep-wake cycle and alleviate related emotional problems in old age, increasing outdoor time and diurnal bright light exposure should be encouraged.
