This study tested whether Marcia's original identity statuses of achievement, moratorium, early closure (a new label for foreclosure), and diffusion, can be considered identity status trajectories. That is, we examined whether these statuses are distinct and relatively stable, over-time configurations of commitment strength,?levels of in-depth exploration of present commitments, and consideration of alternative commitments. The study examined identity development in a five-wave study of 923 early-to-middle (49.3% female) and 390 middle-to-late adolescents (56.7% female), covering the ages of 12-20. Using Latent class growth analysis (LCGA), the authors found that Marcia's (1966) statuses are indeed identity status trajectories. Two kinds of moratorium were also found: the classical moratorium and searching moratorium. Support was found for Waterman's developmental hypothesis of the identity status model: the number of achievers was significantly higher, and the number of diffusions lower, in middle-to-late adolescence than in early-to-middle adolescence. Females were more often in the advanced identity status trajectories, and stable differences were found between the trajectories in psychosocial adjustment. Study findings highlight that identity formation should be conceptualized as an over-time process.  相似文献

The narrative and dual-cycle approach conceptualize and operationalize adolescents’ identity formation in different ways. While the narrative approach focuses on the construction of an autobiographical life story, the dual-cycle approach focuses on the formation of identity commitments. Although these approaches have different emphases, they are conceptually complementary. Yet, their empirical links and distinctions have only scarcely been investigated. Empirical knowledge on these links in adolescence and across time has been especially lacking. In the present research, it was therefore examined whether key characteristics of adolescents’ narration (autobiographical reasoning and agency) were concurrently and prospectively related to engagement in the dual-cycle processes of commitment making, identification with commitment, exploration in breadth, exploration in depth, and ruminative exploration. The findings from a cross-sectional sample of 1,580 Dutch adolescents (Mage?=?14.7 years, 56% female) demonstrated that autobiographical reasoning was significantly positively associated with the commitment and more adaptive exploration processes (i.e., in breadth and in depth). In addition, agency was significantly positively associated with the commitment processes and exploration in depth. Yet, these associations between the narrative characteristics and dual-cycle processes were only weak. Subsequently, the findings from a two-year longitudinal subsample (n?=?242, Mage?=?14.7 years, 62% female) indicated that on average commitment strength remained stable but exploration increased across middle adolescence. A stronger increase in identification with commitment and adaptive exploration (i.e., in breadth and in depth) was predicted by a higher degree of agency in adolescents’ narratives. Overall, these findings indicate that both approaches to identity formation are associated, but the small size of these associations suggests that they predominantly capture unique aspects of identity formation. Both approaches could thus complement and inform each other.

This study focussed on the relationship between the use of seclusion and staff characteristics, such as number of nurses on shift, male-female staff ratio, level of education and level of work experience. A retrospective analysis of staff characteristics was applied to administrative data from ten wards in four mid-sized general psychiatric hospitals in the Netherlands. The data show that two variables were associated with seclusion rates: the male-female staff ratio and the variability in team's work experience. More female and less male nurses in a shift and less variability in team's work experience predicted an increase in seclusion rates.  相似文献

Dyadic variability is considered to be a key mechanism in the development of mother-adolescent relationships, and low levels of dyadic flexibility are thought to be associated with behavior and relationship problems. The present observational study examined heterogeneity in the development of dyadic variability in mother-adolescent interactions and associations with psychosocial functioning. Dyadic variability refers to the range of emotional states during interactions of mother-adolescent dyads. During five annual home visits, 92 mother-adolescent dyads (M age T1 = 13; 65.2 % boys) were videotaped while discussing a conflict, and they completed several questionnaires on adolescents’ aggressive behavior and adolescents’ and mothers’ perceived relationship quality. Two types of dyads were distinguished: low variability dyads (52 %) and high decreasing variability dyads (48 %). Over time, high decreasing variability dyads were characterized by a broader emotional repertoire than low variability dyads. Moreover, these two dyad types had distinct developmental patterns of psychosocial adjustment. Over time, high decreasing variability dyads showed lower levels of adolescents’ aggressive behavior, and higher levels of perceived relationship quality than low variability dyads. These findings suggest that over time more dyadic variability is associated with less adjustment problems and a more constructive development of the mother-adolescent relationship. Adaptive interactions seem to be characterized by a wider range of emotional states and mothers should guide adolescents during interactions to express both positive and negative affect. Observing the dyadic variability during mother-adolescent interactions can help clinicians to distinguish adaptive from maladaptive mother-adolescent dyads.  相似文献

The present study focuses on the individual characteristics, cultural orientation, and ethnic identity of academically successful 17-year-old adolescents of Turkish and Moroccan background in the Netherlands. One hundred and six successful and less successful adolescents of Turkish, Moroccan, and Dutch background participated in the study. The successful ethnic minority students were expected to be highly motivated and determined to succeed. They were thought to have more problems with their ethnic identity as well. It was concluded that success might be explanable in terms of a more positive attitude toward the Dutch society. The successful students did not need to be highly motivated to be academically successful. Although the successful Turkish and Moroccan background students had somewhat more doubts and more negative feelings about belonging to their ethnic group, this does not seem to lead to identity problems.  相似文献
