The literature demonstrates that internalising and externalising difficulties are prevalent in children aged 1-3 years and, in some cases, continue into childhood and adolescence. These difficulties may obstruct an infant's social, emotional and cognitive development and threaten parent-infant attachment security, and therefore a case has been made for the early identification and intervention of difficulties in children aged 1-3 years. However, there are few measurement tools available for use in this age range that are well validated, appropriate for use in clinical and research settings, easily accessible, and inexpensive. The present study aimed to establish the psychometric properties of two measures of internalising and/or externalising difficulties in children aged 1-3 years, namely an adapted version of the Preschool Parental Account of Childhood Symptoms (PPACS-A) and the Strengths and Difficulties Questionnaire (SDQ). Study one involved the confirmation of the factor structure of the SDQ and an exploration of its reliability in a community sample of children aged 12-30 months. Study two involved an exploration of the factor structure, reliability and concurrent validity of the PPACS-A in a preschool sample of children aged 1-3 years, considered at risk of behavioural difficulties. The concurrent validity of the SDQ was also determined using this sample, with an exclusion applied for children above 30 months old. Adequate five factor first order and second order model fit were confirmed for the SDQ. The reliability of the SDQ subscale scores varied, with differences found across infant age and gender. Exploratory factor analysis revealed a three factor structure for the PPACS-A. The reliability of the PPACS-A and its observed factors varied, with the 'disruptive behaviours' factor showing the most promising internal structure. The concurrent validity of the PPACS-A and SDQ were established with the CBCL. The SDQ and PPACS-A show adequate validity but the internal consistency of subscales are inconsistent. The study demonstrates that both measures perform better in the measurement of externalising difficulties such as temper tantrums, oppositionality and aggression. Further exploration of the psychometric properties of the SDQ and the PPACS-A is warranted.
