Identity Formation Re-revisited: A Rejoinder to Waterman on Developmental and Cross-Cultural Issues

This article is a Rejoinder to Waterman's (1999) Commentary on our longitudinal study of identity development (Meeus, Iedema, Helsen, & Vollebergh, 1999). In this rejoinder we consider six points: the similarities and differences between American and Dutch research with respect to (a) the direction of identity development, (b) the relative stability of the statuses, and (c) gender differences; we then discuss (d) the American research on age differences in the frequency of specific patterns of identity status change, (e) the superiority of log-linear analysis compared with cross-table analysis, and (f) age differences with respect to trajectories and mechanisms of identity development. The most important substantive conclusions are that identity development is systematically found to be progressive and may be described with the trajectory diffusion → closure/moratorium → achieving commitment, and that age differences are found with respect to the trajectories but not with respect to the mechanisms of identity development.

The aim of our study is to examine the interface between children's physiological changes and the specificities of parental conflict, and to develop a procedure in which such information can be shared with the family for therapeutic change. Children from 20 families were exposed to parental conflict discussion (CD) while their arousals were measured through skin conductance and heart rate sensors. It was found that regardless of the subject of the argument, 80% of the time they were complaining about each other. Likewise, 80% of the time the children were responding to the parents' own interpersonal tension, including moments of silence. The protocol established for the study, consisting of CD and debriefing, was found to be a powerful tool in moving parents toward conflict resolution.     

The Emerging Gender Gap: Cultural and Economic Conservatism in the Netherlands 1970–1992

Research on gender differences in political alignments and cultural orientations in the past decades reveals a large value change in women relative to that in men, indicating that women might recently have become less conservative than men, whereas women used to be more conservative in many respects. In this article this possible reversal in the gender gap in recent decades is analyzed. Recent research has demonstrated that in the Netherlands women are presently less conservative than men. This lower level of conservatism in Dutch women is apparent with respect to both economic and cultural issues. It is investigated whether these gender differences are due to a reversal in the gender gap in the Netherlands and if so, how this emerging gender gap can be explained. Three explanations are hypothesized: one in terms of the characteristics of the youngest generations (the gender-cohort model), the second in terms of growing structural equality between women and men in general (the situational/structural model), and a specification of the second model, in which differential effects of structural factors for women and men are presumed to have their effect (the gender-interaction model). Neither of the three tested models was in itself able to fully explain the results. The gender gap can partly be explained by growing structural equality between women and men, partly by the fact that the gender gap is largest in the youngest generations (economic conservatism), and partly by the fact that the gender gap is largest between groups of "independent" women and their male counterparts. Possible additional determinants are also discussed.     

Predicting Transitions in Low and High Levels of Risk Behavior from Early to Middle Adolescence: The TRAILS Study

The present study examined the joint development of substance use and externalizing problems in early and middle adolescence. First, it was tested whether the relevant groups found in previous studies i.e., those with an early onset, a late onset, and no onset or low levels of risk behavior could be identified, while using a developmental model of a single, underlying construct of risk behavior. Second, departing from Moffitt's taxonomy of antisocial behavior, it was tested if early, but not late, onset risk behavior is predicted by a problematic risk profile in childhood. Data were used from TRAILS, a population based cohort study, starting at age 11 with two follow-ups at mean ages of 13.6 and 16.3 years. Latent transition analyses demonstrated that, both in early and middle adolescence, a single underlying construct of risk behavior, consisting of two classes (labeled as low and high risk behavior), adequately represented the data. Respondents could be clearly classified into four possible transition patterns from early to middle adolescence, with a transition from high to low being almost non-existent (2.5 %), low to low (39.4 %) and low to high (41.8 %) being the most prevalent, and high to high (16.2 %) substantial. As hypothesized, only the high-high group was characterized by a clear adverse predictor profile in late childhood, while the low-high group was not. This study demonstrates that the development of substance use is correlated with externalizing problems and underscores the theory that etiologies of early and later onset risk behavior are different.     

Patterns of Adolescent Identity Development: Review of Literature and Longitudinal Analysis

A review of theoretical articles demonstrates that the theoretical claims of the identity status model have been greatly moderated over the past 30 years. It has been established that the model is not sufficiently specific to qualify as a developmental theory, and a teleological and unidirectional interpretation of identity development has been abandoned. The development does not have a fixed end-target, achievement, and is also not unidirectional, i.e., always proceeding from the low statuses to the high: a reverse developmental pathway is also possible. The moderation outlined here does not mean that a dominant direction in development must be denied, nor does it conflict with the fundamental developmental hypothesis of the identity status model, which (1) assumes a decrease in diffusion and foreclosure and an increase in achievement during the course of development and (2) specifies a pattern of identity status transitions underlying this progressive development. Reviews of empirical studies on identity development support the first assumption of the fundamental developmental hypothesis but not the second, owing to lack of research. An analysis of empirical studies on the relationship between identity status and psychological well-being further specifies the developmental hypothesis. In view of its associated level of psychological well-being, foreclosure emerges as another possible end-point of identity development, in addition to achievement. The developmental hypothesis and the relationship between identity status and psychological well-being are again addressed in a longitudinal study investigating relational and societal identity in a sample of 1538 Dutch adolescents. Four new identity statuses are used in this study: diffusion, closure, moratorium, and achieving commitment. The results support the first assumption of the developmental hypothesis, although not completely. For relational identity we find a decrease in diffusion and an increase in achievement and for societal identity a decrease in diffusion and an increase in closure. This means that a direction can in fact be indicated in the development of identity, but that closure can also serve as the end-point of the development, particularly for societal identity. Moreover, the domain of societal identity in general displays a less pronounced development than relational identity. This difference between relational and societal identity can be interpreted in terms of the distinction between open and closed domains of identity. In order to test the second assumption of the developmental hypothesis, the patterns of identity development were investigated for the first time in identity status research using log-linear analyses. A number of the status transitions proposed by the developmental hypothesis do not occur, and the developmental pathways are also less comprehensive. We found no indications that identity development proceeds faster in a certain period of adolescence than in other periods. However, the stability of relational identity increases, particularly in postadolescence, and a slow development of identity results in a lower level of psychological well-being.     

How Competent are Adolescent Bullying Perpetrators and Victims in Mastering Normative Developmental Tasks in Early Adulthood?

A substantive body of literature suggests that those involved in bullying as perpetrators but particularly victims are at greater risk for psychological maladjustment. In comparison, relatively little is known about associations between bullying-victimization and perpetration and mastery of early adult tasks in domains including romantic relationships, education, work, financial competence, and conduct. These links were tested using data from two Dutch cohorts (RADAR-young, n = 497, 43% girls; TRAILS, n = 2230, 51% girls) who reported on victimization and perpetration at age 11 (TRAILS) and 13 (RADAR-young) and mastery of developmental tasks in early adulthood. Unadjusted regression analyses suggested for both cohorts that perpetrators were less likely to abide the law and more likely to smoke. Victims in TRAILS were less competent in the domains of education, work, and finances, and more likely to smoke in RADAR-young. Adjusting for childhood demographics and child intelligence and including psychopathology in the prediction models substantially reduced the strength of associations between bullying involvement and later outcomes in both cohorts; although association were retained between victimization and welfare dependence and perpetration and crime involvement in TRAILS. Parental support did not buffer associations in either sample and neither were gender differences detected. Overall, findings underline that negative outcomes of bullying are not only a concern for victims but also for their perpetrators although involvement in bullying is not a stable predictor of mastery of developmental tasks when childhood demographics, child intelligence, and psychopathology are taken into account.

The impact of violations on uncertainty and the consequences for attractiveness

This investigation aimed at extending past research on expectation violations by arguing that violations vary both in valance and in their influence on uncertainty and that the combination of valence and uncertainty states conjointly influences judgments of a violator's social attractiveness. In explaining the predicted variance in uncertainty following violations, a distinction is proposed between congruent violations (i.e., behaviors that are more intense instantiations of a previously displayed message) and incongruent violations (i.e., behaviors that are opposite in meaning from previously displayed messages). Five models for explaining violation effects are contrasted. Results (a) confirm that violations differ in their impact on uncertainty, (b) generally support the validity of the proposed distinction between congruent and incongruent violations, and show that the inclusion of uncertainty and valence in models of violation outcomes accounts for greater variance in social attraction than either one separately.     

Self-determination in relation to quality of life in homeless young adults: Direct and indirect effects through psychological distress and social support

The self-determination theory emphasizes the importance of satisfaction with autonomy, competence, and relatedness for a person’s psychological growth and well-being. This study examines associations between autonomy, competence, and relatedness with quality of life in homeless young adults; and whether possible associations are mediated by psychological distress and perceived social support. By means of face-to-face interviews, 255 homeless young adults who receive care from 10 Dutch shelter facilities for homeless young adults have been interviewed (M age = 20, 77% male, 51% Dutch Nationality) shortly after entering the facility. Autonomy, competence, and relatedness are all associated with quality of life, with competence as the highest correlate. Psychological distress mediates both competence and autonomy, and social support mediates competence as well as relatedness. These findings emphasize the importance of intervention programs for homeless young adults, focusing on the enhancement of self-determination, especially competence, to improve their quality of life.
