An interventional study of ASDactive in Physical Inactivity, Sedentary Behavior and Autism, sponsored by Aberystwyth University. Recruiting at 1 site in United Kingdom. Open to participants aged 10 Years to 24 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-07-24.
Sponsored by Aberystwyth University · Not applicable, Interventional, and Basic science
ASDactive is a theory-based behaviour change intervention aimed at improving the physical activity behaviours of autistic youth. The feasibility of the intervention will be tested through interviews with participants and stakeholders. "Proof of concept" will be tested through preliminary measures of physical activity measured before and after the intervention.
ASDactive is has been developed with guidance from autistic people and stakeholders in autism. It is informed by motivation and behaviour change theory, specifically habit theory. The intervention aims to improve the habitual exercise behaviours of autistic youth by focusing on their strengths and interests.
The feasibility study will run for 3-months, with a further 3-month follow-up period. Participants will attend motivational sessions in person where they will self-select physical activity habits to incorporate into their daily lives. They will be taught fundamental movement skills that they can use in their own leisure time. In-person sessions will be held once per fortnight with online sessions twice weekly. Participants will be encouraged to engage with as many sessions as possible, but part of the evaluation will assess uptake and engagement.
Self-determination theory and habit theory will underpin all aspects of the intervention and autistic strong interests will be embedded in the materials used.

Exclusion Criteria:
Theoretically derived behaviour change intervention aimed at promoting habitual physical activity uptake
Behavioral: ASDactive
An integrated theory-based intervention to promote habitual physical activity behaviours in autistic youth
Feasibility of the intervention through its Adoption
Number of people engaging with the sessions each week
Time frame: 3- months
Feasibility through Implementation
Assessment of the fidelity of the delivery sessions. Two sessions will be recorded and reviewed by two assessors to ensure they are consistently delivered according to the protocol
Time frame: 3- months
Self-Report Habit Index
A scale which measures a combination of subjective estimates (never to always) and recall of behavioural frequency (number of times per week). These are then multiplied by stability of context measured by subjective evaluations (e.g., always in the same place to never in the same place). When frequency and stability are multiplied on the scale, a habit strength between 0-36 is given. Lower scores indicate poor levels of habit strength, higher scores indicated good habit strength.
Time frame: 3- and 6-months as a follow-up
Basic Psychological Need Satisfaction Scale
Measures of basic psychological needs (autonomy, relatedness, and competence) measured on a 7-point likert scale from strongly disagree to strongly agree. Lower scores indicate lower levels of perceived psychological needs being met and so worse outcomes.
Time frame: 3 months
International Physical Activity Questionnaire- Short form
self-report physical activity levels through open-ended questions surrounding individuals' last 7-day recall of physical activity
Time frame: 3- and -6 months as a follow-up
Plan to share: Yes — IPD will be stored in Aberystwyth University's repository for 5-years. IPD will not include personal data belonging to participants but will include anonymised outcome data generated from self-report measures.
