Personality Development from Age 12 to 25 and its Links with Life Transitions

During adolescence and young adulthood, individuals show personality changes and experience various life transitions. Whereas personality might affect the timing of life transitions, life transitions might also induce personality maturation. We examined Big Five personality maturation from age 12 to 25 using a 9-year longitudinal study of Dutch youths from two cohorts (n₁ = 683, M_ageT1 = 12.70; n₂ = 268, M_age T1 = 16.87). We linked personality maturation to the incidence and timing of four transitions: first romantic relationship, leaving the parental home, first job, and first cohabitation or marriage. Results indicated increases in mean levels, rank-order stabilities and profile stability of personality between age 12 and 25, which were largely replicated across the cohorts. Very few associations between personality and life transitions existed. However, higher mean-level Extraversion predicted leaving the parental home and starting the first romantic relationship, an earlier age when starting the first job, and an earlier average timing of transitions. Regarding social investment effects, we only found that those who never experienced a romantic relationship at age 25 decreased, while those who did increased in profile stability over time. These results suggest that personality consistently matures during adolescence and young adulthood and that higher Extraversion predict greater readiness for new steps towards adulthood.     

Discriminant validity of the Conners’ scales for ADHD subtypes

Differential diagnosis and treatment of children with Attention-Deficit/Hyperactivity Disorder (ADHD) remains difficult and controversial, particularly when children present with concomitant academic and behavior problems. Describing a sample of 184 chil-dren referred for evaluation in a university-affiliated outpatient pediatric clinic, this study subsequently examined the discriminant validity of the Conners’ parent and teacher rating scales for ADHD subtypes with and without comorbid conditions. Although discriminant analyses suggest several Conners’ subscales help differentiate subtypes, multimethod evaluations using a variety of data sources are necessary for accurate identification and classification of the disorder with and without comorbid conditions. These data were previously reported at the 107^th Annual Convention of the American Psychological Association, Boston, Massachusetts. The authors express gratitude to Ross D. Crosby, Ph.D., Director of Biomedical Statistics and Methodology at the Neuropsychiatrie Research Institute, for his pre-submission review of the article.     

How Many People Are Exposed to Suicide? Not Six

It has long been stated that six people are left behind following every suicide. Despite a lack of empirical evidence, this has been extensively cited for over 30 years. Using data from a random‐digit dial survey, a more accurate number of people exposed to each suicide is calculated. A sample of 1,736 adults included 812 lifetime suicide‐exposed respondents who reported age and number of exposures. Each suicide resulted in 135 people exposed (knew the person). Each suicide affects a large circle of people, who may be in need of clinician services or support following exposure.     

Reactions to Affirmative Action: Seeking the Bases for Resistance1

It has been argued that affirmative action negatively affects the self‐perceptions of beneficiaries. In contrast, it was hypothesized that this would not occur when individual qualifications were explicitly considered and, indeed, that failure under discrimination would be more self‐detrimental. However, perceptions of reverse discrimination may buffer negative self‐attributions on the part of nonbeneficiaries. Responses in an experimental simulation indicated that, of several affirmative actions for women, passive nondiscrimination was viewed as the fairest response to discrimination. While women's self‐perceptions were not affected by affirmative actions, they did suffer under failure. The presence of affirmative actions did not alleviate the effects of failure on men's self‐perceptions. Possible alternatives for resistance to affirmative action are assessed and discussed.     

Repressive coping and the recall of emotional material

Abstract

Individuals who possess a repressive coping style are known to have difficulty in retrieving negative autobiographical memories. We investigated whether these findings were specific to autobiographical memories. After learning a story containing positive and negative information about mothers and fathers, repressors remembered significantly fewer negative phrases than did controls, although there were no differences in the recall of positive material.
