Outcome measures
Primary outcome
The primary outcome measure will be the difference between the two treatment
groups on general psychopathology as measured by the Symptom Check List
(SCL-90).
Secondary outcome
The secondary outcome measure will be the difference in addiction severity
between the two groups. This will be investigated by a subtest of the Addiction
Severity Index (ASI). An important process measure will be emotion regulation
and will be measured by the Emotion Regulation Questionnaire (EQ).
Background summary
The presence of substance use problems in combination with other mental
illnesses is associated with negative treatment outcomes. Research shows that
integrated treatment for this population is recommended. However, until so far
research has only focused on integrated treatment programs that deal with
manifest symptoms and not on possible psychological origins, like youth trauma,
parenting style and problems in emotion regulation.
Study objective
The aim of this study is to compare the effectiveness of Group Schema Therapy
(G-ST) and Group Cognitive Behavioral Therapy (G-CBT+MI) on symptoms, emotion
regulation and addiction in DD outpatients. Moreover the effect of the severity
of childhood maltreatment experiences, parenting style and degree of secure
attachment on the effectiveness of G-ST will be investigated. At last, it will
be examined whether security of attachment improves during therapy.
Study design
We will conduct a Randomized Controlled Trial (RCT), a
pretest-midtest-posttest-3-month-12-month-follow-up-design, with two treatment
conditions: the experimental condition (G-ST) and the control condition
(G-CBT+MI).
Intervention
Patients assigned to the experimental condition will receive 30 weekly sessions
(2 hours) of G-ST, plus 3 preparatory individual meetings. Patients in the
control condition will also start with 3 individual meetings, followed by 30
weekly sessions (2 hours) of G-CBT+MI.
Study burden and risks
As far as we know the current study is not associated with risks. The burden is
that patients have to fill in questionnaires which costs them time (5 times
1.5-2 hours). Moreover, the questionnaires could evoke negative emotions. The
benefit of attending the study is that people are being treated for their
psychiatric disorder.
