| Abstract: | This prospective, longitudinal study investigated the moderating role of pubertal timing on reciprocal links between adolescent appraisals of parent–child relationship quality and girls' (N=1,335) and boys' (N=1,203) cigarette and alcohol use across a 12‐month period. Reciprocal effects were found between parent–child relations and on‐time maturing boys and girls' cigarette and alcohol use, after estimating stability in these constructs across time. Parent–child relationship quality was associated with increased alcohol use 12 months later for early maturing girls. Cigarette and alcohol use were associated with increased problems in the parent–child relationship for late maturing girls. No effects were observed for early and late maturing boys in the pathways between parent–child relationship quality and substance use. Pubertal timing moderated the pathway linking parent–child relationship quality with cigarette use 1 year later such that the association was stronger for late maturing girls compared with early and on‐time maturing girls. The findings indicate interplay between the psychosocial aspects of maturation, family relationships, and adolescent substance use and highlight possible gender‐specific influences. |
