A Brief Cognitive Analytic Therapy–Informed Approach for Young People That Have Self‐Injured (CATCH‐Y): A Case Series

ABSTRACT Background Non‐suicidal self‐injury (NSSI) presents an increasingly prevalent problem for young people; however, there remains a scarce evidence base for effective, scalable treatments for adolescents. This study aimed to assess the feasibility and acceptability of a brief, cognitive analytic therapy (CAT)–informed intervention for young people who engage in NSSI (CATCH‐Y). Methods A case series design recruited 13 young people who met the inclusion and exclusion criteria to participate in the five‐session intervention. Eligible participants were aged 13–17 years (M = 15.15, SD = 1.28) and had engaged in NSSI at least once in the previous 6 months. Feasibility and acceptability were measured via recruitment, retention, qualitative feedback and missing data. The secondary outcome measures of personal recovery and motivation were administered pre‐ and post‐assessment, with measures of depressive symptoms and urges to self‐injure. Results The intervention was found to be largely feasible and acceptable with high rates of recruitment, retention and pre‐/post‐assessment data completeness. Measures showed preliminary support for positive change in rates of NSSI, urges to self‐harm, low mood and personal recovery, although results were mixed. Completion rates for remote assessments were low. Conclusions The findings of this study support further evaluation of the CATCH‐Y intervention on a larger scale. In‐person assessments may be preferable to remote to ensure good completion rates.
