Abstract
Background: Behavior Change Technique Taxonomy v1 (BCTTv1) has been used to detect active ingredients of interventions. Purpose: Evaluate effectiveness of user training in improving reliable, valid and confident application of BCTTv1 to code BCTs in intervention descriptions. Methods: 161 trainees (109 in workshops and 52 in group tutorials) were trained to code frequent BCTs. The following measures were taken before and after training: (i) inter-coder agreement, (ii) trainee agreement with expert consensus, (iii) confidence ratings and, (iv) coding competence. Coding was assessed for 12 BCTs (workshops) and for 17 BCTs (tutorials). Trainees completed a course evaluation. Results: Methods improved agreement with expert consensus (p<.05) but not inter-coder agreement (p=.08, p=.57 respectively) and increased confidence for BCTs assessed (both p<.05). Methods were as effective as one another at improving coding competence (p = .55). Training was evaluated positively. Conclusions: Training improved agreement with expert consensus, confidence for BCTs assessed, coding competence but not inter-coder agreement. This varied according to BCT.
