The goal of this clinical trial is to study whether a Cognitive Behavioural Therapy for Insomnia (CBT-I) group led by laypersons serves as an effective tool for alleviating insomnia in older Chinese adults in Hong Kong. The main questions it aims to answer are: 1) Can the group improve subjective sleep quality? 2) What is the feasibility and acceptability of the group? Researchers will compare the intervention group with a control group. Participants will either join the intervention group or receive a self-help booklet, depending on their assignment. Both groups will complete two questionnaires over a four-week period: Baseline and Week-4 data.

Subjective sleep quality
Brief Version of the Pittsburgh Sleep Quality Index (B-PSQI): Likert scale with a global scoring ranging from 0 to 15. A higher score indicates worse sleep quality.
Time frame: From first session to last session at 4 weeks.
Dysfunctional Beliefs and Attitudes about Sleep
A 16-items scale ranging from 0 (Strongly Disagree) to 10 (Strongly Agree). Stronger endorsement of these beliefs indicates greater maladaptation in detecting therapeutic changes and effectiveness.
Time frame: From first session to last session at 4 weeks.
Pre-sleep Arousal Scale
Rated on a 5-point Likert scale, ranging from 1 (Not at all) to 5 (Extremely), with total scores ranging from 8 to 40 for both subscales. Higher scores indicate an increased level of pre-sleep arousal.
Time frame: From first session to last session at 4 weeks.
