Psychometric Properties of the Parental Bonding Instrument in a Sample of Canadian Children.

The parental bonding instrument (PBI) is a self-report questionnaire that was initially designed to retrospectively assess perceived parenting style during childhood in adult respondents. Recent studies have used the PBI to assess current perception of parenting in children. However, few studies have evaluated the psychometric properties of the PBI in children. This study examined the factor structure and reliability of the PBI in a sample of Canadian children aged 7-18 years (n = 257). Confirmatory factor analyses (CFA) were conducted separately for the mother and father form of the PBI and composite reliability was used to determine internal consistency of the PBI. A four-factor model (care, overprotection, autonomy, indifference) showed the best fit to the data. The PBI exhibited good internal consistency but poor convergent validity. Configural invariance was not found for the PBI between two age groups (7-12 and 13-18 years), however these findings should be interpreted with caution due to the small sample size in each age group. This study suggests the PBI may be a valid and reliable self-report measure of parental bonding in children but further research is needed.
