I Know What to Do; I Can Do It; It Will Work: The Brief Parental Self Efficacy Scale (BPSES) for Parenting Interventions.

Abstract

Parental self-efficacy predicts outcomes for parenting interventions for child behaviour problems, but there is a need for a brief measure that can be repeated over treatment and applies to a wide age range. The present study describes the development of such a measure, the Brief Parental Self-Efficacy Scale (BPSES). The psychometrics of the BPSES is presented across a wide age range from preschool to late adolescent in a sample comprised of four different intervention contexts. Evidence for structural validity, internal consistency, content validity, configural measurement invariance (equivalent factor structure) and test-retest reliability is presented alongside convergent validity against measures of parental self-efficacy, child behaviour problems, as well as self-report and observed parenting styles. Finally, lower levels of BPSES at baseline predicted increased disengagement from an intensive, individualised family therapy intervention for antisocial youth, while higher baseline levels predicted increased response to a group parenting programme for primary school aged children. The BPSES shows promise as a measure that can be used across a wide age-range, for a variety of parenting interventions for disruptive behaviour problems and which is sufficiently brief to be used as a routine outcome measurement during treatment.
