The Impact of Relationship Stressors on Trust and Prorelationship Behavior Within Adolescent Romantic Relationships: A Systems Approach. J Adolesc Health. 2021;68(3):558-564. doi:10.1016/j.jadohealth.2020.06.043https://hdl.handle.net/1805/33397Purpose: Trust is an essential component of romantic relationships. It is not understood how youth respond to a relationship stressor, which may impact trust, such as perceiving to be at risk for a sexually transmitted infection or their partner has other sex partners. We used a system science approach to examine feedback between trust and prorelationship behaviors within adolescent relationships. Methods: A prospective cohort of clinic-recruited young women (N = 122), aged 16-19 years, completed daily questionnaires on partner-specific feelings and risk perceptions for 18 months. Relationship stressor defined as either perceiving the risk of sexually transmitted infection from a partner or partner had other sex partners. Prorelationship behaviors were more time spent with partner, sex with partner, and/or gift from partner. Time-lagged generalized estimating equation models were used to examine whether a relationship stressor is associated with a decrease in trust and whether prorelationship behaviors changed following the stressor. Results: Experiencing a stressor was associated with threefold increased odds of having a decrease in trust in the same week (odds ratio [OR] = 3.30, 95% confidence interval [CI]: 2.30-4.72). Trust increased significantly the week following the stressor (OR = 2.09, 95% CI: 1.54-2.85). An increase in trust relative to the week of the stressor was associated with a 65% increase in prorelationship behavior in the week following the stressor (OR = 1.65, 95% CI: 1.20-2.26). Conclusions: Data uniquely show that trust is impacted following a relationship stressor and that youth increase prorelationship behaviors following a drop in trust. The findings suggest that adolescents prioritize maintaining trust, which may impact engagement in protective health behaviors.en-USPublisher PolicyConcurrencyIntensive longitudinal dataProrelationship behaviorsRisk perceptionRomantic relationshipsSystems scienceTrustArticle
