A decline in tolerance of child abuse along with a rise in awareness and mandatory reporting of child abuse has created increased demand for psychological input into the assessment of parenting capacity. The evaluation of parenting skills is vital in understanding the capacity of parents to meet the needs of their children. Based from an ecological approach and the wider parenting literature, the present research develops and tests a new measure of parenting: The Parenting Skills Assessment (PSA). The aim is to enable the reliable evaluation of a parent’s repertoire of parenting skills. The studies in this project included: a look at the relationship between the PSA and alternative measures of parenting, an investigation of the relationship between the PSA and the direct observation of behaviour from parent-child interactions, a test of the differences in PSA scores between clinical and general community samples, an examination of the differences in PSA scores between mothers at-risk of child maltreatment and mothers in general community and an investigation of the change in pre-post PSA scores in a parenting intervention study. The studies revealed the PSA to have good reliability, construct validity (concurrent and discriminant) and that the PSA is sensitive to change in parenting skills after completion of a parenting intervention. Power problems due to small sample sizes and attrition interfered with some relationships reaching significance. Further studies were conducted to investigate participant responses to the PSA in more depth and improve the clinical utility of the measure. The PSA can elicit a broad range of parenting skills, providing the practitioner valuable information about a parent’s strengths as well as any potential deficits in their care of children. The results indicated that further research as to the practical value of the PSA in clinical and child protection settings is warranted.
