This study examines the stability of and change in self-control during adolescence and investigates the reciprocal relationship of self-control and parental social control. German three-wave panel data with two age cohorts (11–13 and 15–17 years, total N = 1423) are analyzed. Latent growth curve and path models are applied to investigate developmental trajectories. Findings suggest (a) no evidence for the relative stability of self-control, (b) parental controls do matter after the formative years, and (c) low self-control influences the perception of parental controls in early adolescence. In sum, results support a dynamic perspective with reciprocal influences of self-control and social control.
