Parenting is a multifaceted task and the way in which parents fulfill this task plays an important role in children's growth and development, especially in early childhood. Conceptualization and assessment of parenting behavior is elementary for research on child and family development and would fill a gap in clinical work, as there is a lack of questionnaires simultaneously assessing multiple parenting behaviors specific for early childhood. Therefore the Comprehensive Early Childhood Parenting Questionnaire (CECPAQ) was designed; a parent report measure of commonly occurring behaviors in five domains of parenting (i.e., support, stimulation, structure, harsh discipline, and positive discipline) central to early childhood. Data were collected from 1139 mothers and 526 fathers of 1-4 year-old children. Confirmatory factor analysis confirmed a five-factor structure (composed of 54 items). The five parenting domains were found to have good internal consistency and temporal stability. Preliminary evidence of validity of the CECPAQ was demonstrated by moderate relationships with measures of parental stress and child problem behavior. It is concluded that the CECPAQ is a promising measure of self-perceived parenting behavior for parents of 1-4 year-old children.
