Data from the Christchurch Health and Development Study, a 30-year prospective longitudinal study, were used to examine the associations between the quality of parent-child relations in adolescence and adult parenting behaviour 15 years later. At ages 14 and 15 years, cohort members were interviewed about the quality of their relationship with their parents. At age 30, those who had become parents underwent a parenting assessment using self-report and observational ratings of positive (warmth, sensitivity) and negative parenting (overreactive, inconsistency, and physical punishment/abuse). Results showed that adolescents who reported higher quality parent-child relationships were later characterized by higher levels of parental warmth, sensitivity, and effective child management, and lower levels of overreactive parenting. These associations remained after extensive covariate adjustment. Study findings highlight the importance of close parent-child relations during adolescence in preparing an individual for the challenges of caring for and parenting their own children when they themselves become parents. examined the intergenerational transmission of supportive parenting in a small ethnically diverse sample of low-income families. Results revealed a moderately strong correlation (r = .43) between the extent of parental supportive presence and quality of assistance across the first-generation (G1) and second-generation (G2) parents, with this association being only slightly reduced following adjustment for parent IQ, child IQ, and family stress. In another study, Neppl, Conger, Scaramella, and Ontai (2009) examined the transmission of both punitive and positive parenting in a sample of rural youth first recruited in early adolescence. Results showed that harsh parenting by the G1 predicted harsh parenting in the G2, and similarly, positive parenting by G1 predicted positive parenting by G2.Adult externalizing problems mediated associations between G1 and G2 harsh parenting, and adult academic attainment mediated the association between G1 and G2 positive parenting. These cross-generational parenting studies suggest that parents in successive generations of the same families tend to employ similar parenting strategies, with individual characteristics and/or later life-course experiences playing an important mediating role (Conger, Belsky, & Capaldi, 2009). Alongside this body of research, several studies also highlight the important influence of an adult's internal working model of earlier childhood attachment relationships on their current parenting behaviour (for reviews, see Mikulincer & Shaver, 2007; van IJzendoorn, 1995). Parents classified as having dismissive and preoccupied attachment representations on the Adult Attachment Interview (AAI) are less warm and sensitive towards their children than parents with an autonomous attachment style (Cohn, Cowan, Cowan, & Pearson, 1992;Pederson, Gleason, Moran, & Bento, 1998;Raval et al., 2001). For example, Cohn et al. (1992) found that both mothers and fathers class...
