Predictions from smoking-specific versus contextual models of smoking onset were tested with data from a 4-wave sample with 1,364 adolescents. Predictor variables were derived from stress-coping theory, social influence theory, and problem-behavior theory. In addition to groups of abstainers and experimenters, cluster analysis of smoking data indicated 3 groups who showed onset either in 7th grade (early onset), 9th grade (intermediate onset), or 10th grade (late onset). Almost all study variables discriminated the smoking groups from the abstainers. The onset groups were discriminated by Group X Time interactions showing differential changes in predictors (increases in risk factors and declines in protective factors), which occurred just prior to onset. The results generally support a contextual model of the onset process. 相似文献

Dissociative disorders that are believed to develop from childhood sexual abuse are often considered to include amnesia for childhood events, particularly the events that involve the abuse itself. One unresolved issue is the extent to which memory recovery attempts can contribute to claims of having amnestic symptoms. Experiments with undergraduate subjects reveal that requiring more reports of childhood events will increase judgments of having poorer memory of one’s childhood. The results are consistent with the use of heuristics when one is reasoning under conditions of uncertainty, as experienced difficulty in remembering more experiences is attributed to the incompleteness of childhood memory. The findings challenge the validity of reports of childhood amnesia that follow memory recovery attempts. 相似文献

Integrating career construction (Savickas, 2013) and cognitive evaluation (Ryan & Deci, 2002) theories, we examined the moderating role of traditionality beliefs in the indirect relationships among parental support, career decision-making self-efficacy and career adaptability among Chinese university students. Data were collected from 731 undergraduate students in China at two measurement periods, 18 months apart. Results showed that Time 1 parental support was associated positively with Time 1 career decision-making self-efficacy and Time 2 career adaptability. In addition, the conditional indirect effects of Time 1 parental support in predicting Time 2 career adaptability via Time 1 career decision making self-efficacy were stronger among students with low as opposed to high traditionality beliefs. The implications of the results in terms of theory and practice are discussed. 相似文献
