Abstract

A total of 3,243 rural older adults were studied to examine the link between activities of daily living and suicidal ideation.

Activities of daily living directly affects suicidal ideation with a coefficient of β=0.092.
Sleep quality mediates this relationship, accounting for 9.79% of the total effect.
Psychological distress serves as a significant mediator, accounting for 25.26% of the total effect.
The combined mediation effect of sleep quality and psychological distress accounts for 17.53% of the total effect.
Overall, the total mediating effect of sleep quality and psychological distress is 52.58%.

Simplified

Few studies clarified the mechanisms underlying the relationship between activities of daily living and suicidal ideation among older adults. This study aimed to explore the multiple mediating roles of sleep quality and psychological distress between this relationship. A total of 3,243 rural older adults were included. Multiple mediation analysis was performed using Mplus 8.3. Activities of daily living was found to directly affect suicidal ideation (β=0.092, 95% CI=0.043-0.140) and through three significantly mediation pathways: (1) the path through sleep quality (β=0.019, 95% CI=0.007-0.031), which accounted for 9.79 % of the total effect; (2) the path through psychological distress (β=0.049, 95% CI=0.036-0.063), which accounted for 25.26 % of the total effect; (3) the path through sleep quality and psychological distress (β=0.034, 95% CI=0.026-0.042), which accounted for 17.53 % of the total effect. The total mediating effect was 52.58%. Attention should be paid to sleep quality and mental health among the Chinese rural older adults with activities of daily living limitation. For early detection and prevention of suicidal ideation, it is necessary to take sleep-based and positive psychological interventions for older adults with activities of daily living limitation.
