Background summary
Depression is highly prevalent: More than 15% of the adult population under 65
had major depression in their history according to DSM-III-R criteria. Minimal
interventions are effective in the treatment for depression. The purpose of
this study is to investigate the efficacy of two minimal interventions with
adults reporting elevated depressive symptoms. The two interventions are
cognitive-behavioural therapy (Color your life) and self-examination therapy
(Alles onder controle).
Study objective
Main question:
* Are the minimal interventions effective in reducing depressive symptoms
comparing to a waitinglist-controlgroup?
Subquestions:
* Do the interventions differ in effectiveness?
* Are the effects specific for the interventions?
* Are there subgroups who respond different to the interventions?
Study design
People will be recruited through advertisements in local newspapers and
websites. Inclusion criterion is a score of 16 or higher on the Center for
Epidemiological Studies Depression scale (CES-D). Participants are assigned on
a random basis to two treatment conditions and a delayed-treatment condition.
Both interventions are delivered through computer administration. During the
interventions respondents receive support by email. Respondents in the
delayed-treatment condition receive the interventions three months later. Data
are collected at baseline and at 5 weeks, 8 weeks, 12 weeks and 9 months after
baseline. Data are collected by email.
Intervention
The cognitive-behavioural intervention is called Color your life (Kleur je
leven). This intervention consists of 8 lessons (1 lesson a week). Four weeks
later, the 9th lesson takes place. The intervention focuses on increasing
pleasurable activities, increasing social skills and decreasing dysfunctional
cognitions.
Self Examination Therapy is based on problem solving therapy. We used the Dutch
version, called 'Alles onder controle'. This intervention takes 5 weeks. During
this intervention participants determine what matters to them, think less
negatively about things that do not matter to them, invest their energy in
things that are important to them (by using problem-solving strategies) and
accept situations they cannot change.
Both interventions are computer-based.
Study burden and risks
Burden: participants receive a questionnaire five times. Filling in takes at
most 60 minutes each time.
