Self‐Concept Clarity in Adolescents and Parents: A Six‐Wave Longitudinal and Multi‐Informant Study on Development and Intergenerational Transmission

The purpose of this study was twofold: (a) to disentangle patterns of change and stability in self‐concept clarity (SCC) in adolescents and in their parents and (b) to examine processes of intergenerational transmission of SCC in families with adolescents. Participants were 497 Dutch families including the father (baseline M_age = 46.74), the mother (baseline M_age = 44.41), and their adolescent child (56.9% males; baseline M_age = 13.03). Each family member completed the SCC scale for six waves, with a one‐year interval between each wave. Latent growth curve analyses indicated that adolescent boys reported higher SCC than girls. Furthermore, fathers and mothers reported higher SCC than their children, and it increased over time. Indices of SCC rank‐order stability were high and increased from T1 to T2, T2 to T3, etc., for each family member, especially for adolescents. Multivariate latent growth curve analyses and cross‐lagged models highlighted a unidirectional transmission process, with fathers’ and mothers’ SCC influencing adolescents’ SCC. This result was not moderated by adolescent gender. These findings indicate that self‐concept clarity is transmitted from parents to children.
