The educational intervention was presented for 5 weeks by lecture, group discussions and virtual learning methods. Data were collected by the Pittsburgh Sleep Quality Index and the Ryff’s Psychological well-being scale before and 2 months after the intervention. The data were analyzed using SPSS-25 software using independent t-test, and Chi-square test. Results: The results showed significant statistical differences in sleep quality, subscales of sleep efficiency, sleeping time, and taking sleeping pills in experimental and control groups after the intervention (p≤0.005). Moreover, significant statistical difference was observed in terms of the mean scale of psychological well-being between experimental and control groups (p=0.036). Conclusion: Behavioral interventions can make various advantages for elderly people. Therefore, this study suggests providing such interventions in a wide range in comprehensive health centers, and boarding centers for the elderly. [ABSTRACT FROM AUTHOR]

The risk factors were revealed significantly higher in females than males (p<0.05)., Conclusion: The incidence of the risk factors among the females showed higher than males patients.
