The KPCS measures perceived parenting self-efficacy (PPSE) in parents of children aged 0-12 months. High PPSE has been shown to act as a buffer against factors that can compromise a child's development, such as parental depression, anxiety, stress and relationship difficulties, and is associated with actual parenting competence and positive child outcomes

The KPCS is a short self-report instrument. It was developed in Australia primarily for health professionals experienced in working with parentcraft and psychosocial issues of early parenthood, including Maternal, Child and Family Health Nurses, and allied health and medical professionals.
