This pilot study demonstrated that an online cognitive behavioral therapy (CBT) life skills course effectively recruits and retains participants with depression. The findings support its use in a larger randomized controlled trial (RCT) for depression treatment.
Area of Science:
- Mental Health
- Psychology
- Digital Health
Background:
- Depression is a prevalent mental health issue with significant consequences.
- Cognitive Behavioral Therapy (CBT) is effective but often inaccessible due to limited practitioner availability.
- Low-intensity interventions, such as online guided self-help, can improve service access.
Purpose of the Study:
- To pilot a randomized controlled trial (RCT) of an online CBT-based life skills course for community-based individuals with depression.
- To assess the feasibility of recruitment, randomization, and intervention delivery.
- To gather data for sample size calculation for a future substantive RCT.
Main Methods:
- Community participants with depression symptoms were recruited via newspaper advertisements.
- Participants were randomized to immediate or delayed access to an online CBT package with telephone support.
- Outcomes assessed at 3 months included depression, anxiety, social functioning, and satisfaction.
Main Results:
- Effective recruitment, randomization, and uptake were achieved.
- The online intervention was acceptable to participants, with a mean satisfaction score of 21/32.
- Data collection success rate was 78%, informing a power calculation for a future RCT requiring 72 participants.
Conclusions:
- The pilot study successfully validated the research design for recruitment, data collection, and intervention delivery.
- The study provided essential data for determining the sample size for a full-scale RCT.
- This approach shows promise for increasing access to CBT-based interventions for depression.
