In this experiment the IV is when the participants start their treatment process. There are 2 groups, one group starting their treatment almost immediately and another group starting it after 11 weeks have past. Another IV is what type of therapy the applicant will be participating. The participant could either have to participate in the web-CBT treatment or the face-to face treatment. A dependent variable is a measurable response or behavior. In this case, the dependent variables are the number of participants who completed the treatment and the effectiveness of the treatment long term. There is a chart that shows how many participates completed their program from both groups. They also figure out how effective the treatment was depending on the clients score on the 18 month follow-up questionnaire compared to their post-treatment follow-up …show more content…
The web-CBT had an effect size of .9 which is close to the effect size of face-to-face treatment. There was a low drop-out rate of 10% which is very good seeing how poor adherence has been identified as one of the major challenges in online intervention. 47% the participates in the web-CBT condition recovered immediately after the treatment. The effects of both face-to-face and web-CBT treatments were found to be stable and helpful long term. So this web-CBT treatment made a lasting difference. Pharmacotherapy was highly predictive in relapse in the long run. Participant who were taking antidepressant during the treatment may have stop taking the medication due to the short-term improvements as a result of the Internet treatment. And the improvements could have been made not due to the efforts of the participants but because of the medication. And the clients who started to take medication may have started to take them because they weren't seeing long-term results from the web-CBT. Due to this information, experiments should control for medication in a stricter manner in the future. In despite of this both treatments, the present one and the Internet-based guided self-help program of Andersson et al appear to be equally effective in the long
