Cognitive behavioural therapy (CBT) training is highly demanded by clinicians; however, a standardized competence assessment for professionals working with children and young people (CYP) can be problematic. Psychometric tools used for this purpose are typically adult oriented measures.
The present study provides psychometric properties of the Cognitive Behaviour Therapy Scale for Children and Young People (CBTS-CYP) derived from a comparative analysis with the Cognitive Therapy Scale (CTS).
The CBTS-CYP was used alongside CTS in a CBT supervision training course, consisting of a cohort of 51 therapists. A total of 36 audio/video recorded full CBT sessions were assessed for the purpose of determining CBT competence and adherence to the theory and model. The training involved a total of 80 hours of supervision in 10 meetings via an online videoconferencing platform between July 2020 and February 2021.
Face validity and inter-rater reliability of CBTS-CYP were high, with the intraclass correlation values being good (0.60–0.74) or excellent (0.74 and above); the correlations of each CBTS-CYP and CTS items were significant; internal consistency of the scale showed that Cronbach alpha values for total-scale and its two subdimensions were above .93. For a cut-off score of 55 out of 90, sensitivity reached 90.73% and specificity 90.73%. A score of 2 points or above from any single item could be considered as the second minimum criterion for competence.
CBTS-CYP offers a valid and reliable scale to evaluate the competence and adherence quality of CBT sessions with children and adolescents.
