Study Stopped
The study was 'completed' within allocated timeframe. However, we were unable to recruit the initial target number of adolescent participants, thus concluding it is not currently feasible to recruit adolescents to complete the intervention.

Outcome Measures
Primary Outcomes (3)
Number of Adolescent Participants Recruited
A total of 8 adolescents were referred between October 2023 and October 2024. Of these, 1 was ineligible, 4 declined participation / did not respond, and 3 provided consent and were enrolled.
1 year
Number of Adolescent Participants Who Attend Each Session
Measured through attendance logs. This outcome reports the number of adolescent participants who completed each session of the 4-session intervention.
Over 4 session intervention period (1 - 4 months) 1-4 months 1-4 months
Intervention Fidelity
Fidelity was assessed using an intervention delivery checklist. Practitioners were categorised based on whether they delivered the intervention as intended or deviated. Of the 10 practitioners who completed training, only 3 practitioners delivered the intervention, but only 2 submitted fidelity data for this outcome.

Limitations and Caveats
Recruitment and retention of adolescents was challenging. Key barriers included: most adolescents had diagnosis of NDD (exclusion criteria), time pressure and demands on the services made it difficult to implement. Qualitative feedback only obtained from practitioners, therefore, not able to examine acceptability from adolescents' perspective.
