Neural correlates of self-evaluation in relation to age and pubertal development in early adolescent girls.

ABSTRACT: Early adolescence is marked by puberty, and is also a time of flux in self-perception. However, there is limited research on the neural correlates of self-evaluation in relation to pubertal development. The current study examined relationships between neural activation during self-evaluation of social traits and maturation (age and pubertal development) in a community sample of female adolescents. Participants (N?=?143; age M?=?11.65, range?=?10.0-13.0) completed a functional MRI task in which they judged the self-descriptiveness of adjectives for prosocial, antisocial and social status-related traits. Pubertal development was based on self-report, and was also examined using morning salivary testosterone, dehydroepiandrosterone, and estradiol. Contrary to preregistered hypotheses, neither age nor pubertal development were related to neural activation during self-evaluation. We further examined whether activation in two regions-of-interest, the ventromedial prefrontal cortex (vmPFC) and perigenual anterior cingulate (pgACC), was associated with trial-level self-evaluative behavior. In line with preregistered hypotheses, higher vmPFC and pgACC activation during self-evaluation were both associated with a higher probability of endorsing negative adjectives, and a lower probability of endorsing positive adjectives. Future studies should examine neural trajectories of self-evaluation longitudinally, and investigate the predictive value of the neural correlates of self-evaluation for adolescent mental health.

Project description:BackgroundAdolescent girls in Nigeria are at heightened risk for HIV and other sexually transmitted infections. However, there are limited studies on psychosocial factors that are associated with safe sex intentions among this population. Self-efficacy has been established as an important correlate of behavioral intentions and the actual behavior. The objective of this research was to examine how key psychosocial factors such as social support, parental monitoring, and future orientation influence perceived safe sex self-efficacy among in-school adolescent girls in Nigeria. Furthermore, we assessed the associations between these psychosocial factors and HIV-related knowledge and safe sex self-efficacy.MethodsA self-administered questionnaire was distributed to 426 adolescent girls attending public and private school systems in Lagos, Nigeria. Multiple linear regression was used to evaluate the influence of psychosocial and demographic factors on safe sex self-efficacy. Further, stratified analysis was conducted to compare the estimates between participants attending public schools (n = 272) and those attending private schools (n = 154).FindingsResults from the study show that future orientation (β = 0.17; p < 0.05), participants age (β = 0.14; p < 0.05), and HIV knowledge accuracy (β = 0.17; p < 0.05) were associated with safe sex self-efficacy. Future orientation remained statistically significant in the sub-group analysis among participants attending public (β = 0.13; p < 0.05) and private schools (β = 0.24; p < 0.05). Among participants attending public schools, HIV accuracy (β = 0.2; p < 0.05) remained a significant correlate of safe sex self-efficacy while this association dissipated among private school attendees.ConclusionsThese findings point to the importance of including future orientation strategies in interventions developed for in-school adolescent girls in Nigeria. School-based interventions that increase positive future orientation outcomes may be beneficial to improve safe sex intentions among adolescent girls in Nigeria.
