Hypothesis
Is Internet-based cognitive behavioral therapy (CBT) or problem-solving therapy (PST) more effective for treating depressive symptoms compared to a waiting list control group?
Conclusion
Both Internet-based treatments are effective in reducing depressive symptoms, although the effect of PST is realized more quickly.
Supporting Evidence
- 263 participants were randomized to three conditions: CBT, PST, and WL.
- 70% of participants completed questionnaires after 5 weeks.
- Effect sizes for depressive symptoms were medium for both CBT and PST.
- 34 participants in CBT and 30 in PST showed clinically significant improvement at 12 weeks.
Takeaway
This study shows that people with depression can get better using online therapy, and one type of therapy works faster than the other.
Methodology
A 3-arm randomized controlled trial comparing Internet-based CBT, PST, and a waiting list control group.
Potential Biases
Participants were not blind to their condition, which could introduce bias.
Limitations
High attrition rates and potential selection bias due to recruitment methods.
Participant Demographics
Participants were mainly female (71%), with a mean age of 45 years, and most were from the Netherlands (92%).
