suggestions on how they may support their child by means of ACT, and connection with other parents of autistic children.

Design outcomes

Primary

MeasureTime frame
The goal of the current observational multicenter pilot study is to investigate if an 8-week Acceptance and Commitment group therapy for youth with ASD is an effective intervention to increase adaptive emotion regulation, psychological flexibility and quality of life. For this we have selected several parameters which are suitable for multiple measurements due to brevity and ease (multilevel single case (MSC) design, whilst other parameters are most suitable for pre-post-follow up design to provide more comprehensive insights into the functioning of the participants and the effects of the intervention (pre-post-follow up design). Primary Objectives: To assess - Emotion regulation --> o FEEL-KJ (Braet et al., 2013) (pre-post-follow up) o Valuing Questionaire (VQ) (Smout, 2014) (pre-post-follow up and MSC) - Psychological flexibility --> o Avoidance and Fusion Questionnaire for Youth (AFQ-Y) (Greco et al., 2008) (pre-post-follow up) o Valuing Questionaire (VQ) (Smout, 2014) (pre-post-follow up and MSC) - Quality of life --> o Mental Health Quality of Life (MHQoL) (van Krugten et al., 2022) (pre-post-follow up and MSC)

Secondary

MeasureTime frame
Secondary Objective(s): In addition, we want to investigate if the treatment has any effect on emotional and behavioral problems and general functioning (e.g., attending school or not; utilization of other (mental) healthcare). To assess: - Emotional and behavioral problems --> o Youth/Adult Self Report (YSR/ASR) and Child Behavior Checklist (CBCL; ASEBA,(Verhulst et al., 1989, 1996) (pre-post-follow up) - Demographic questions --> o School attendance (pre-post-follow up) o Utilization of (mental) healthcare (pre-post-follow up) Lastly, we will use some information for baseline/comparison to ROM data and/or elements which may be influential on our measurements or potential desired side-products: - Autistic traits --> o Social Responsiveness Scale (SRS-2/SRS-A) (not expected to change, but possibly an influential factor on the success of the intervention) (Roeyers et al., 2011) - Current feeling (start of session) --> o Visual Analogue Scale (VAS; not expected to change but a potentially influential factor on our outcome measures and a potential by-product of the intervention).
