简要总结
This study aims to evaluate the efficacy of a psychoeducational intervention targeting the determinants of university students' sleep health. It is conducted as part of a doctoral research project.
The intervention consists of three structured sessions delivered over three weeks, with additional online follow-ups. Each session lasts 1.5 hours and takes place in the evening, with a one-week interval between sessions.
Session 1 focuses on providing fundamental knowledge about sleep health. Session 2 introduces behavioral strategies to improve sleep health and asks participants to implement behavior change intentions.
Session 3 reviews the implementation of the intention, the changes made or not, and addresses the relationship between stress and sleep, along with coping strategies.
Participants are required to complete online questionnaires and a sleep diary at multiple time points: before the intervention, immediately after, and up to three months post-intervention. These assessments measure sleep habits, beliefs about sleep, and mental health indicators.
Participants are randomly assigned to one of two groups:
Intervention group, which receives the psychoeducational program first. Waitlist control group, which completes an additional follow-up before receiving the intervention.
The study design allows for a controlled evaluation of the intervention's impact on sleep-related behaviors and mental health outcomes.
详细描述
A process evaluation will be conducted immediately after the 3 weeks intervention to assess participants' comprehension, adherence to the intervention, as well as the accessibility and relevance of intervention content. Moreover, in terms of logistics, this involves evaluating the premises used, the facilitator, the size of the group, the number and length of sessions, the face-to-face offer, and the use of teaching aids such as manuals during the sessions. These data are collected to inform potential improvements in future iterations of the intervention and are not included as outcome measures.

研究组 & 干预措施
Intervention group
Participants assigned to the intervention group will receive first the intervention. They will complete various assessment at baseline (T0), post-intervention after the 3 weeks of intervention (T1), and 3 months after the end of the intervention (T2).
干预措施: Sleep health education (Behavioral)
Waitlist control group
Participants assigned to the waitlist control group complete a baseline assessment (T0), a second assessment after 3 weeks of waiting (T1), and then receive the intervention. They are assessed again after the intervention (T2) and at 3-month follow-up (T3). This design allows for pre- and post-intervention comparisons while ensuring delayed access to the program.
干预措施: Sleep health education (Behavioral)
结局指标
主要结局
RU-SATED
时间窗: Intervention group: T0 (day 1), T1 week 4 (post 3 weeks intervention), T2 week 16 (3 months post-intervention). Waitlist control group: T0 (day 1), T1 (3 weeks later T0), T2 week 8 (post 3 weeks intervention), T3 week 20 (3 months post-intervention).
RU-SATED is the instrument used to measure sleep health. Sleep health varies according to individual, social and environmental conditions, and emphasises that good sleep is not simply the result of an absence of sleep disorders. In terms of its components, sleep health relates to (1) sleep duration, or the total number of hours of sleep obtained over 24 hours, (2) sleep efficiency, corresponding to the ease or otherwise with which an individual falls asleep and returns to sleep, and (3) timing, or how our sleep fits into a 24-hour day, (4) alertness, or sleepiness, which concerns a person's ability to maintain a state of attentive wakefulness throughout the day, (5) satisfaction, or subjectively represented sleep quality, and finally (6) sleep regularity. More specifically, RU-SATED score is distributed between 0 and 12, with the higher the score, the better the person's sleep health.
Sleep satisfaction
时间窗: 1-week daily self-reports at each time point: T0 (day 1), T1 week 4 (post 3-week intervention), T2 week 16 (3-month follow-up); waitlist group: T0, T1 (3 weeks later), T2 week 8 (post 3-week intervention), T3 week 20 (3-month follow-up).
Sleep satisfaction will be assessed using a single-item question from a sleep diary completed by participants each morning for seven consecutive days. The item reads: "How would you rate the quality of your sleep?" Responses are recorded on a 5-point Likert scale ranging from 1 ("very restless") to 5 ("Very deep"). Daily scores will be summed to obtain a total sleep satisfaction score ranging from 7 to 35. Higher scores indicate a higher perceived sleep quality. The measure provides a subjective evaluation of sleep quality from the participant's perspective.
Sleep regularity
时间窗: 1-week daily self-reports at each time point: T0 (day 1), T1 week 4 (post 3-week intervention), T2 week 16 (3-month follow-up); waitlist group: T0, T1 (3 weeks later), T2 week 8 (post 3-week intervention), T3 week 20 (3-month follow-up).
Measured via self-reported bedtimes and wake-up times across multiple days using a sleep diary. Variability will be calculated using the standard deviation of sleep and wake times to assess sleep regularity.
Sleep timing
时间窗: 1-week daily self-reports at each time point: T0 (day 1), T1 week 4 (post 3-week intervention), T2 week 16 (3-month follow-up); waitlist group: T0, T1 (3 weeks later), T2 week 8 (post 3-week intervention), T3 week 20 (3-month follow-up).
Self-reported bedtime and wake-up time recorded daily in a sleep diary. Used to calculate the timing of sleep onset and wake time, as well as midpoint of sleep.
Sleep efficiency
时间窗: 1-week daily self-reports at each time point: T0 (day 1), T1 week 4 (post 3-week intervention), T2 week 16 (3-month follow-up); waitlist group: T0, T1 (3 weeks later), T2 week 8 (post 3-week intervention), T3 week 20 (3-month follow-up).
Calculated from self-reported sleep diary entries as the ratio of total sleep time to time in bed, expressed as a percentage.
Sleep duration
时间窗: 1-week daily self-reports at each time point: T0 (day 1), T1 week 4 (post 3-week intervention), T2 week 16 (3-month follow-up); waitlist group: T0, T1 (3 weeks later), T2 week 8 (post 3-week intervention), T3 week 20 (3-month follow-up).
Self-reported total sleep time calculated daily using sleep onset and wake-up time entries in the sleep diary.
