Incorporating the social context into neurocognitive models of adolescent decision-making: A neuroimaging meta-analysis.

ABSTRACT: Neurobiological models of adolescent decision-making emphasize developmental changes in brain regions involved in affect (e.g., ventral striatum) and cognitive control (e.g., lateral prefrontal cortex). Although social context plays an important role in adolescent decision-making, current models do not discuss brain regions implicated in processing social information (e.g., dorsomedial prefrontal cortex). We conducted a coordinate-based meta-analysis using the Multilevel peak Kernel Density Analysis (MKDA) method to test the hypothesis that brain regions involved in affect, cognitive control, and social information processing support adolescent decision-making in social contexts (N?=?21 functional neuroimaging studies; N?=?1292 participants). Results indicated that dorsomedial prefrontal cortex, inferior frontal gyrus/insula and ventral striatum are consistently associated with adolescent decision-making in social contexts. Activity within these regions was modulated by the type of social context and social actors involved. Findings suggest including brain regions involved in social information processing into models of adolescent decision-making. We propose a 'constructionist' model, which describes psychological processes and corresponding neural networks related to affect, cognitive control, and social information processing.

Project description:ObjectivesDespite significant public health emphasis on unintended pregnancy prevention among adolescent girls and young women in Sub-Saharan Africa, there is a gap in understanding how adolescents' own reproductive priorities and the social influences on their decision-making align and compete. We examined the social context of contraceptive decision-making among Kenyan female adolescents.MethodsUsing community-based sampling, we conducted 40 in-depth interviews and 6 focus group discussions among sexually-active or partnered adolescent girls and young women aged 15-19 in the Nyanza region of Kenya. We analyzed the data in Dedoose using an inductive, grounded theory approach, and developed a conceptual model from the data illustrating social influences on adolescent contraceptive decision-making.ResultsParticipants viewed adolescent pregnancy as unacceptable, and described severe social, financial, and health consequences of unintended pregnancy, including abortion under unsafe conditions. Yet, their contraceptive behaviors often did not reflect their desire to delay pregnancy. Contraceptive decision-making was influenced by multiple social factors, centering on the intersecting stigmas of adolescent female sexuality, pregnancy, and contraceptive use, as well as unequal power in sexual relationships. To prioritize pregnancy prevention, adolescents must navigate conflicting social norms and power dynamics, and put their perceived future fertility at risk.ConclusionsContraceptive decision-making among Kenyan female adolescents is strongly influenced by opposing social norms within families, communities, and sexual relationships, which compel them to risk stigma whether they use a contraceptive method or become pregnant as adolescents. These findings put into perspective adolescents' seemingly incongruent pregnancy preferences and contraceptive behaviors. Interventions to address adolescent unintended pregnancy should focus on supporting adolescent decision-making agency, addressing fertility-related contraceptive concerns, and promoting innovative contraceptive access points rather than increasing contraceptive prevalence.
