Self-fulfilling prophecy effects of mothers' beliefs on children's alcohol use: accumulation, dissipation, and stability over time.

This research examined whether self-fulfilling prophecy effects accumulated, dissipated, or remained stable over time in terms of 2 complementary conceptual models. Analyses of longitudinal data from 2 samples of mother-child dyads (N(1) = 487; N(2) = 288) yielded 3 main findings. First, the degree to which mothers' inaccurate beliefs assessed at a single point in time predicted children's distal alcohol use did not differ from the degree to which they predicted children's proximal alcohol use, thereby supporting a pattern of stability for the samples on average. Second, mothers' inaccurate beliefs repeatedly assessed across time had additive self-fulfilling effects on their children's subsequent alcohol use assessed at a single later point in time. Third, these additive self-fulfilling effects served to exacerbate differences in the alcohol use of children who had been consistently exposed to unfavorable versus favorable beliefs year after year. The authors discuss these findings in terms of the link between self-fulfilling prophecies and social problems.
