Development And Validation Of The Trainee Rated Impact Of Involvement Index (Triple-I) In Clinical Psychology Training

PurposePrevious research suggests that service user and carer involvement (SUCI) in clinical psychology training may have an impact. The purpose of this study was to develop a validated questionnaire to enable trainee clinical psychologists to rate this.Design/methodology/approachA collaborative project was carried out with service users and carers and trainee clinical psychologists. The principles of questionnaire design were followed. The authors developed and validated a trainee self-report questionnaire, based on focus groups and relevant literature indicating potential impacts of involvement on practice. A draft 60-item version was piloted with 15 trainee clinical psychologists. Then, 133 trainees from 22 UK clinical psychology courses completed it (estimated response rate of 13.2%). The sample was representative of UK trainees in gender and ethnicity, but slightly older.FindingsThe principal component analysis produced a 36-item questionnaire with four factors: human communication, carer perspectives, empathy and challenging/changing. The questionnaire showed good internal consistency and test-retest reliability. Stakeholder consultation suggested face and content validity and there was some indication of construct validity.Originality/valueThe project has resulted in a usable co-produced questionnaire, which is now available to clinical psychology courses to assess the self-reported impact of SUCI in training, and which may also be used in future research.
