Developmental paths of psychological health from early adolescence to later adulthood

Developmental paths of psychological health were examined for 236 participants of the Berkeley Growth Study, the Berkeley Guidance Study, and the Oakland Growth Study. A clinician-reported aggregate index, the Psychological Health Index (PHI), based on California Q-Sort ratings, was created for subsets of participants at 14, 18, 30, 40, 50, and 62 years of age. Latent curve analysis was then used to explicate the life span development of psychological health. Psychological health development could be successfully modeled via 2 piecewise latent growth curves. Psychological health appears to be stable in adolescence and to steadily increase from 30 to 62 years of age. A moderately strong positive correlation between the 2 developmental curves indicates that those with greater psychological health in adolescence show more improvement in adult psychological health tend to also. Results illustrate the value of the PHI and the power of latent curve analysis to explicate longitudinal stability and change.     

Developmental status and AIDS attitudes in adolescence.

We postulated that among adolescents and young adults, the development of consistent and responsible attitudes with respect to acquired immunodeficiency syndrome (AIDS) precautions would follow a pattern similar to that of the development of a sense of identity. Late-adolescent trainee teachers and nurses (N = 262) were administered identity and intimacy measures and a questionnaire measuring attitudes toward and knowledge of AIDS prevention. Attitudes were shown to be conceptually complex, with dimensions expressing the identity statuses of diffusion, foreclosure, moratorium, and achievement. Few relationships were found between AIDS attitudes and sex, course, measures of identity, or intimacy. However, attitudes toward AIDS precautions and identity status were predictive of future intention to use a condom. Intimacy level was negatively related to such an intention, suggesting that those in steady relationships may not recognize the need for AIDS protection.     

Developmental trends in dichhaptic lateralization

Two studies on developmental trends in dichhaptic lateralization for nonlinguistic stimuli were conducted on school-aged children. Study 1 included 60 students in Grades 1, 5, and 9. Study 2 included 200 students from Grades 2, 4, 6, 8, and 10. Both studies showed significant age-related increases in over-all dichhaptic accuracy. In Study 2 a significant left-hand advantage for all subjects as well as an over-all advantage for boys were noted. Significant interactions indicated different developmental trends for boys and girls but did not show clear patterns in the development of lateralization.     

Developmental change in subjective probability during adolescence

The developmental change in subjective probability during adolescence, an important period for establishing the probability concept, was investigated. 75 Japanese adolescents, from 12 to 23 yr. of age, were asked to make probability judgments for a lottery under 15 conditions. Analysis showed that with increase in age their subjective probability came closer to the objective probability. Discussion of these results took into consideration recent studies on the development of the concept of probability.     

Dramatic-erratic personality disorder symptoms: II. Developmental pathways from early adolescence to adulthood

This study examined the relationship over time between Cluster B personality disorder symptoms (borderline, histrionic, and narcissistic symptoms) and comorbid internalizing and externalizing symptoms in a community sample of 407 adolescents. Cross-lagged longitudinal models tested (a) the hypothesis that Cluster B symptoms reflect primary disturbances that give rise to co-occurring internalizing and externalizing symptoms; and (b) the alternative hypothesis that these Axis I symptom clusters reflect primary problems that interfere with normal personality development. Internalizing and externalizing symptoms each predicted subsequent Cluster B symptoms in girls, although these effects occurred only at specific developmental stages. Cluster B symptoms in boys and girls at ages 10 to 14 years predicted externalizing symptoms two years later. Instead of clearly supporting one hypothesis over the other, longitudinal models suggested gender-specific developmental effects that were partially consistent with both hypotheses.     

Parent-adolescent conflict in early adolescence

This study explored parent-adolescent conflict during the early years of adolescence (ages 11 to 14). The responses of 357 youths in Grades 6, 7, and 8 to the Issues Checklist (Prinz, Foster, Kent, & O'Leary, 1979) revealed frequent conflicts with parents over a sizable number of issues during this period, peaking in Grade 7 between parents and sons, with exchanges between parents and daughters consistently more than those with sons across the three grades. There was considerable variation in both the frequency and intensity of conflict across specific issues. In addition, a consistent pattern of gender-typing was observed in conflicts between parents and daughters, reflecting traditional gender role stereotypes. The results of this study point to the importance of examining both the frequency and intensity of conflict, the specific issues over which there is conflict, and the gender of the participants in order to more fully understand the nature of parent-adolescent conflict during early adolescence.     

Developmental change in speed of processing during childhood and adolescence

Throughout childhood and adolescence, there are consistent age differences in speed of processing. Here 72 published studies yielded 1,826 pairs of response times (RTs) in which each pair consisted of adults' mean RT for a condition and the corresponding mean RT for a younger group. The primary results were that (a) children's and adolescents' RTs increase linearly as a function of adult RTs in corresponding conditions and (b) the amount of increase becomes smaller with age in a manner that is well described by an exponential function. These results are consistent with the view that age differences in processing speed reflect some general (i.e., nontask specific) component that changes rapidly during childhood and more slowly during adolescence. Possible candidates for the general component are discussed.     

Career-choice readiness in adolescence: Developmental trajectories and individual differences

Developing career-choice readiness is an important task in adolescence, but current theory and research has provided a rather static view of the phenomenon. The present study investigated the development of career-choice readiness among a group of 325 Swiss students assessed four times every 5 months from seventh through eighth grade. A variable-centered approach applying latent curve modeling showed not only a linear increase of readiness over time but also significant inter-individual differences in the level and development of readiness. Higher levels were predicted by more self-esteem and generalized self-efficacy and fewer perceived barriers while increase in readiness was predicted by increase in occupational information. A person-centered approach applying latent class-growth analysis identified four distinct developmental trajectories: high-increasing (42%), high-decreasing (5%), moderate-increasing (42%), and constantly low (11%). Students with different trajectories showed significant differences in core self-evaluations, occupational knowledge, and barriers. The results suggest that environmental demands promote a developmental trend in readiness development that overrules individual differences for the majority of students. Individual differences affect the level of readiness to a greater extent than the process of its development. Career information seems pivotal for readiness increase.     

Developmental stability and change in self-regulation from childhood to adolescence

The authors examined the developmental course of self-regulation in a cohort of children from the National Longitudinal Survey of Youth. The longitudinal sample included 646 children (48% girls; 52% boys; 36.2% Black, 23.4% Hispanic, 40.4% White) who were 4 to 5 years old in 1986 and who were followed up at ages 8 to 9 and ages 12 to 13. Levels of self-regulation (assessed with 12 maternal-report items that measured regulation of affect, behavior, attention) increased from early childhood (when sample children were 4 or 5 years old) to middle childhood (ages 8 or 9), but not from middle childhood to early adolescence (ages 12 or 13). Girls exhibited significantly higher levels of self-regulation than did boys at all 3 time points. Individual differences in self-regulation were fairly stable across the 8-year span (rs = .47 to .50). Comparisons of 1-, 2-, and 3-factor models suggested that the different aspects of self-regulation are highly interrelated, and support adoption of a single-factor model for both genders. The authors discuss implications of these findings for theory and intervention.     

Moral judgment and antisocial behavior in early adolescence

This project was designed to assess the relationship of moral judgment to a naturalistic measure of antisocial behavior—delinquent and predelinquent behavior. As a prelude, observations were made which confirmed that delinquents not only have low scores on the Kohlberg Moral Judgment Interview, but also that Rest's Defining Issues Test distinguishes incarcerated delinquent from nondelinquent groups. In the present study, each of a group of boys with disruptive and antisocial behavior was matched with a counterpart on 14 variables so designed as to minimize the effect of factors other than the stage of development of moral judgment in members of the two groups on the outcome of the testing procedures. When the impact of these extraneous factors was so minimized, results of Rest's Defining Issues Test revealed significant differences between the groups, while Kohlberg's interview did not. Clinical implications of this project are discussed.     

Risk factors for depression in early adolescence

The purpose of this study was to identify salient risk factors for depression in early adolescence from a group of common predictors. The following nine predictors were examined: (1) perceived quality of peer relationships, (2) perceived parental nurturance, (3) perceived parental rejection, (4) self-esteem, (5) body image, (6) pubertal status, (7) SES, (8) conduct problems, and (9) hyperactivity/inattention. The sample of 2,014 12 and 13 year olds was also divided by gender to examine potential sex differences in risk factors for depression. Finally, several mediational models were investigated. Self-esteem emerged as the strongest predictor of depression in both genders; parental behavior also emerged as an important risk factor. Therefore, these two variables are discussed as targets for those developing intervention and prevention programs.     

Developmental trends in the understanding of perceptual adaptation

In the first of three studies, kindergartners, third graders, and sixth graders were questioned to determine whether they comprehend five types of perceptual adaptation or contrast effects. The results indicated little consistency among kindergartners, but there were strong improvements by the third-grade level, and at the sixth-grade level almost all of the children were showing perfect performance, demonstrating comprehension of the five forms of perceptual adaptation. In the second and third studies, children and adults were placed in a situation in which adaptation to temperature and weight could occur, and they were asked to predict subsequent perceptions. Correct performance in these studies generally occurred at later ages than in Study 1 with even college students showing incorrect performance in some cases. However, the age trends shifted quite markedly depending upon the nature and structure of the task. The results were consistent with a theory stressing the relation of early formed schemas in the form of memory traces of experiences to later appearing and more abstract schemas. The results show the importance of studying older children when considering developing theories of mind.     

Developmental trends in cue utilization for attributional judgements

Fourth through twelfth graders of both sexes were tested for developmental trends in making causal attributions for success and failure and in using past history, social comparison, and importance information in making their attributional judgements. Results suggested that basic information processing rules had already developed by the fourth grade but that children continue to develop and become more consistent in applying these rules. Sex differences indicated that girls were more defensive generally in not taking responsibility for their outcomes by attributing them externally.
