Scientific title
Randomised multicentre controlled trial of group-based social skills training in children and adolescents with high functioning autism spectrum disorder (SOSTA-Net)
Acronym
SOSTA net
Study hypothesis
To establish efficacy of group-based social skills training (SST) in children and adolescents with high functioning autism spectrum disorder (HFASD). It is hypothesised that add-on group-based SST using a manualised therapy-program will result in improved social responsiveness compared to treatment as usual (TAU), including no treatment (waiting list). In addition, a neurophysiological substudy in the Frankfurt subgroup (N = 60) will be performed pre- and post-treatment to explore changes in neuronal function induced by SST versus TAU. It is further expected that specific functional genetic variants will mediate treatment outcome. Functional genetic variants will be assessed in all participants.

1.2. 3 x parent training
1.3. Add-on therapy to treatment as usual (TAU)
2. Control intervention:
2.1. Treatment as usual (TAU), including waiting list, excluding group-based therapy
2.2. 3 x parent training
Follow-up per patient: three months

Primary outcome measure
Change in total raw score of the Social Responsiveness Scale (SRS) as assessed by the primary caretaker (PC), measured:
1. Between baseline and end of intervention
2. Between baseline and 3 months after end of intervention
Secondary outcome measures
Measured 0 and 3 months after end of intervention:
1. Response to intervention: Individual symptom reduction of at least 16 raw points in SRS total score (PC and teacher [T] assessment)
2. Change in SRS total raw score (T)
3. Change in SRS subscale raw scores (PC, T)
4. Change in anxious-depressive symptoms (CBCL:PC)
5. Change in total psychopathology, pro-social behaviour, and peer related problems (SDQ: PC, T)
6. Change in depressive symptoms (DIKJ, self assessment)
7. Motivation and satisfaction with therapy (self assessment)
8. Change in neuronal function during cognitive and affective empathy tasks
9. Assessment of genetic variants and medication as possible mediating variables of therapeutic effect
10. Assessment of safety: serious adverse and adverse events will be documented
