The timing and pace of pubertal development has been associated with psychosocial functioning, with pubertal variables represented both as predictors (e.g., earlier puberty linked with poor outcomes) and as sequelae (e.g., early stress linked with earlier puberty). However, the literature has largely not tested mediational models or prospective mechanisms(More)
PURPOSE Dysmenorrhea affects quality of life and contributes to absenteeism from school and work, thereby diminishing opportunities for successful psychosocial and cognitive development during adolescence. In adults, depression, anxiety, and smoking have an impact on menstrual cycles and dysmenorrhea. Associations between these problems have not been(More)
PURPOSE To examine the differences in depressive symptoms and anxiety between (a) normal weight and overweight, and (b) morning type and evening type (sleep chronotype) adolescent girls. The interaction of sleep chronotype and weight and depressive symptoms and anxiety were also examined. METHOD The design consisted of a cross-sectional study of 264(More)
This study examined the relationship between pubertal timing and delinquent behavior across two time points in a sample of 303 maltreated and 151 comparison adolescents aged 9-13 years at enrollment. The first aim was to examine the relationship between pubertal timing and delinquency for the total sample and then to test for gender differences using(More)
The purpose of this study was to examine the associations between Morningness/Eveningness (M/E; a measure of sleep-wake preference) and alcohol, cigarette, and marijuana use as well as the interaction of M/E and pubertal timing. The data represent baseline measures from a longitudinal study examining the association of psychological functioning and smoking(More)
Among the explanations for the high rates of co-occurrence between depressive symptoms and externalizing behavior is the possibility of direct causal associations between the two symptom groups. However, the mechanisms by which co-occurrence arises may not be the same across etiologically significant variables. A gender-balanced sample of 303 adolescents(More)
This cross-sectional study examined relationships between pubertal development, depressive symptoms and delinquency in a sample of 241 males and 213 females aged 9-13 years. Four objectives were set forth for this study: 1) to examine relationships between pubertal stage or timing and depressive symptoms and delinquency; 2) to compare continuous and(More)
OBJECTIVE Two types of sleep preference have been supported in the literature. Morning types awaken early and are refreshed upon waking, whereas Evening types rise later and have more erratic sleep schedules. Sleep affects menstrual functioning in adult women. However, there is scant research on the association between sleep preference and menstrual(More)
BACKGROUND Little is known about psychosocial correlates of different contraceptive methods in adolescence. STUDY DESIGN Cross-sectional analyses of 209 postmenarcheal girls [mean age (years)+/-SD=15.68+/-1.74], primarily Caucasian (62.8%) or African American (32.8%). Competence (activities and social) and rule-breaking behavior were assessed by the Youth(More)
This prospective, longitudinal study examined a sample of sexually abused and comparison girls to determine (a) whether there were patterns of behavior that differed between the groups and (b) whether nonverbal behaviors assessed at the initial visit (n = 147; M = 11.11 years; SD = 3.02) might predict sexual attitudes and behaviors at a later point in(More)
