It is unknown whether perceived pubertal timing changes as puberty progresses or whether it is an important component of adolescent identity formation that is fixed early in pubertal development. The purpose of this study is to examine the stability of perceived pubertal timing among a school-based sample of rural adolescents aged 11-17 (N=6,425; 50% female; 53% White). Two measures of pubertal timing were used, stage-normative, based on the Pubertal Development Scale, a self-report scale of secondary sexual characteristics, and peer-normative, a one-item measure of perceived pubertal timing. Two longitudinal methods were used: one-way random effects ANOVA models and latent class analysis. When calculating intraclass correlation coefficients using the one-way random effects ANOVA models, which is based on the average reliability from one time point to the next, both measures had similar, but poor, stability. In contrast, latent class analysis, which looks at the longitudinal response pattern of each individual and treats deviation from that pattern as measurement error, showed three stable and distinct response patterns for both measures: always early, always on-time, and always late. Study results suggest instability in perceived pubertal timing from one age to the next, but this instability is likely due to measurement error. Thus, it may be necessary to take into account the longitudinal pattern of perceived pubertal timing across adolescence rather than measuring perceived pubertal timing at one point in time. 相似文献

Through the nation's first century, states used their concurrentconstitutional right to schedule presidential and House electionsat widely varying times. Senators were also elected within thestates at diverse times. This study examines the gradual establishmentof uniform election dates and offers an explanation of why Congressfelt it appropriate to override state autonomy to eventuallyestablish uniformity of state practices. 相似文献

An increase in adolescent distress and mental health symptoms has been clearly documented since the COVID-19 pandemic, as has increased exposure to adverse childhood experiences. Layer on top of these stressors being a youth of divorcing or separating high conflict families, and adolescent symptomatology can suddenly become a flashpoint for parental attention, division and conflict. Approaching cases using an ecological and family systems framework is necessary for accurate conceptualization and assessment of best interests in the context of child custody evaluations. Doing so ensures that adolescent mental health does not become a red herring in high conflict cases, leading to undue focus on the adolescent's mental health without considering other salient factors in the case, such as the broader parent conflict. Programs offered at the Center of Excellence for Children, Families & the Law at William James College designed to improve the lives of youth by addressing parental conflict are described. 相似文献
