Grip Op Je Dip Online (Master your Mood Online)


Grip Op Je Dip Online (Master Your Mood Online) is a structured group course for depression administered through a chat room format.  The program is based on Lewinsohn's Coping with Depression course and includes 8 sessions.  These focus on understanding your mood, identifying and changing negative thoughts, enhancing participation in enjoyable activities, training in assertiveness and handling conflict, and planning to prevent relapse.  The chat room involves a number of participants with supervision from a mental health professional who directs discussion.  Prior to each session you are encouraged to complete homework so that you are familiar with each weekly topic and discussions are more helpful.  The site is not appropriate for you if you have severe depression, suicidal thoughts, self-mutilation, or are not motivated.

Outcome Summary:

An initial non-experimental pilot study examined the utility of the Grip op Je Dip online program. The study tested adolescents with sub-clinical and mild depression. Participants who completed the program showed a significant reduction in depressive symptoms based on the CES-D scale (t=8.23, df = 48, p<.001) and reported that the program was satisfying and effective, particularly due to its anonymity and social support. In a subsequent trial a significant reduction in CES-D scores was identified in an adolescent sample who completed the program compared to pre-test measures (t=47.8, sd 12.7, p<.001). Moreover, in a recent randomised controlled study, 121 young people who completed the Grip op Je Dip Online intervention showed a significantly greater improvement in depressive symptoms at 3 months than the wait-list control group (with a large between-group effect size of 0.94). In fact, the intervention group also showed a significantly greater reduction in anxiety symptoms (with a medium between-group effect of 0.49). Further, this reduction in depressive and anxiety symptoms was maintained among the intervention group after 6 months. Therefore, evidence to date suggests Grip op Je Dip Online is an effective treatment for both depression and anxiety among adolescents and young adults.
