简要总结
Rationale: Although there are effective treatments available for anxiety and depression, there is a large group of clients that does not benefit sufficiently from first-choice treatment. For this group of clients, no suitable alternative exists yet. One of the main hypothesis about maintaining factors is that there are underlying personality features that impede recovery. Schema focused therapy (SFT) is a transdiagnostic therapy focusing on underlying personality features. It has been proven to be an effective therapy for people with personality disorders and there are initial indications that SFT is also an effective treatment for anxiety and depressive symptoms. A short-term schema focused group therapy (SFGT) has been developed within GGZ-NHN, which is expected to benefit clients with persistent anxiety and depressive symptoms, but has not yet been studied.
Objective of the study: In the present study the effectiveness of short-term SFGT (protocol of De Jager, Burger & Groot) on (1) persistent anxiety and depressive symptoms, and (2) early maladaptive schemas (EMS), experiential avoidance and the mode of the healthy adult will be investigated.

排除标准

结局指标
主要结局
Anxiety and depressive symptoms, as repeatedly measured by (an idiosyncratic set of) a self-report questionnaire; the Depression Anxiety Stress Scales-21 (DASS-21).
时间窗: From baseline to follow-up, total of 37-40 weeks. We will administrate 10 items, idiosyncratically chosen. Measured once every 4 days.
The DASS-21 consists of three subscales (Depression, Anxiety, and Stress). Each item can be rated on a scale from 0 ("Did not apply to me at all") to 3 ("Applied to me very much or most of the time"). All subscales content 7 items which makes the score range 0-21 for each subscale. Higher scores indicate the experience of more severe symptoms
次要结局
- Early maladaptive schemas as measured with the Young Schema Questionnaire Short Form (YSQ-S3).(From baseline to follow-up, total of 37-40 weeks. Complete YSQ will be filled in 5 times during study. Two early maladpative schema's, 10 items, idiosyncratically chosen will be measured once every 16 days)
- Personality pathology as measured by the Level of Personality Functioning-screener brief form (LPFS-BF);(25 weeks; before start baseline and after finishing therapy)
- Experiential avoidance as measured with the Brief Experiential Avoidance Questionnaire (BEAQ).(From baseline to follow-up, total of 37-40 weeks. BEAQ will be filled in once every 16 days)
- Schema modi as measured with the Schema Modi Inventory (SMI)(From baseline to follow-up, total of 37-40 weeks. Complete SMI will be filled in 5 times during study. Mode of the healthy parent, 10 items, will be measured once every 16 days)
- General psychopathology as measured by the (totalscore of the) Outcome Questionnaire (OQ-45)(37-40 weeks; OQ-45 will be filled in 5 times during study)
