41. A simple intervention for sleep-related social media use and its impact on sleep quality
Use of mobile devices shortly before bedtime has been associated with sleep disturbance among college-aged students. The present longitudinal study tested the feasibility and effectiveness of a simple behavioral sleep intervention that asked students not to use mobile devices shortly before bedtime.
College students (N=122) completed self-report measures assessing sleep-related social media use and sleep quality at baseline, a 2-week crossover, and 4-week post-test. They also completed daily sleep diaries throughout the duration of the study. Growth curve modeling, within a multilevel modeling framework, was used to examine whether the intervention led to changes in sleep-related social media use and sleep quality.
Results indicated that sleep-related social media use significantly declined over the course of the study, t(119)= -4.43, p<.001. Analysis of Insomnia Severity Index (ISI-5) scores suggested that sleep changes did not follow a systematic linear trajectory, x2(2)=1.82, p>.500. On average, ISI-5 sleep scores also did not vary as a function of sleep-related social media use, t(120)=1.20, p=.231. However, there was significant between-subject variability in the nature of this relationship, x2(115)=143.48, p=0.037. Preliminary results demonstrate that simple behavioral interventions may be an acceptable and effective way to target behaviors associated with sleep disturbance in college students.
