Brief interventions for carers of people with substance use disorder

Phase 1 - quantitative data collected through a semi-structured interview using Qualtrics to determine the needs of carers of people with substance use disorder. Phase 4 - quantitative data on the effectiveness of the Care4Carers Programme, evaluated through a pre-experimental, one-group pretest/posttest design using a standardised scale, the Coping Self-efficacy Scale (CSES), which was administered before and after exposure to the programme to evaluate its effectiveness.
