Community-based group guided self-help intervention for low mood and stress: randomised controlled trial

Area of Science:

• Mental Health
• Psychology
• Public Health

Background:

• No prior studies evaluated written cognitive-behavioural therapy (CBT) resources for low mood and stress in community self-help classes.
• This study addresses the gap by assessing a community-based CBT program.

Purpose of the Study:

• To evaluate the effectiveness of an 8-week community-based CBT self-help group intervention.
• To assess the impact on symptoms of depression, anxiety, and social function at 6 months.

Main Methods:

• 142 participants were randomized into immediate or delayed access groups for the low-intensity CBT intervention.
• Depression, anxiety, and social function were measured at baseline and 6 months.

Main Results:

• Significant improvement in the primary outcome (Patient Health Questionnaire-9 score) was observed (mean difference: -3.64, P = 0.004).
• 43.8% of the immediate access group showed a 50% or greater reduction in PHQ-9 scores, compared to 17.9% in the delayed group.
• Secondary outcomes, including anxiety and social function, also improved. The intervention was cost-neutral.

Conclusions:

• Class-based, low-intensity CBT delivered in community settings is effective for reducing depression, anxiety, and social dysfunction.
• The intervention offers a cost-effective approach to improving mental well-being in community settings.
