Perceived control in adolescent substance use: concurrent and longitudinal analyses.

A sample of 9th-grade students (1,293 individuals, 51% girls) attending compulsory schools in Reykjavik, Iceland, was surveyed and followed up 3 years later. The relationship between perceived control and substance use is examined concurrently at age 14 for experimentation with tobacco and alcohol and longitudinally (14-17 years of age) for daily smoking, heavy drinking, and illicit drug use. Taking into account sociodemographic characteristics (family structure, socioeconomic status, and gender) and parental and peer use, the results of concurrent analyses indicate that adolescents who expressed more personal control were less likely to have smoked and to have had a drink at age 14. Longitudinal analyses showed that perceived control at age 14 predicted both daily smoking and illicit drug use among girls at age 17 but not among boys. Conversely, perceived control did not predict heavy drinking among adolescents.

How schoolchildren propose to negotiate: the role of social withdrawal, social anxiety, and locus of control.

The role of social anxiety, social withdrawal, and locus of control in the developmental level of interpersonal negotiation strategies (INS) when resolving hypothetical conflicts was examined in a short-term longitudinal study (fall and spring). Applying a balanced design, 96 children aged 8 and 11 from 8 classes participated in the study. At both assessments, results indicated that sociable children were more likely to exhibit greater competence in INS than socially withdrawn children. However, both concurrent and longitudinal analyses indicated that degree of social anxiety tended to influence this relation. Among less socially anxious children, the sociable children did exhibit greater INS competence than those more socially withdrawn, but this relation was not revealed among the more socially anxious children. Finally, on the whole, children who showed internal locus of control were more competent at INS than children with external locus of control.
