    The impact of relationship stressors on trust and pro-relationship behavior within adolescent romantic relationships: A systems approach
    (Elsevier, 2021) Matson, Pamela A.; Chung, Shang-en; Fortenberry, J. Dennis; Lich, Kristen Hassmiller; Ellen, Jonathan M.; Pediatrics, School of Medicine
    Purpose: 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.

    Weekly variations in feelings of trust predict incident STI within a prospective cohort of adolescent women from a US city FREE
    (BMJ, 2018) Matson, Pamela A.; Fortenberry, J. Dennis; Chung, Shang-en; Gaydos, Charlotte A.; Ellen, Jonathan M.; Pediatrics, School of Medicine
    Objectives Feelings of intimacy, perceptions of partner concurrency (PPC) and perceptions of risk for an STD (PRSTD) are meaningful and dynamic attributes of adolescent sexual relationships. Our objective was to examine whether variations in these STI-associated feelings and perceptions predicted incident Chlamydia trachomatis and/or Neisseriagonorrhoeae infection within a prospective cohort of urban adolescent women. Methods A cohort of clinic-recruited women aged 16–19 completed daily surveys on feelings and risk perceptions about each current sex partner on a smartphone continuously for up to 18 months. Urine was tested for C. trachomatis and N. gonorrhoeae every 3 months. Daily responses were averaged across the week. As overall means for trust, closeness and commitment were high, data were coded to indicate any decrease in feelings from the previous week. PRSTD and PPC were reverse coded to indicate any increase from the previous week. An index was created to examine the cumulative effect of variation in these feelings and perceptions. Generalised linear models were used to account for correlation among repeated measures within relationships. Results For each week that there was a decrease in trust, there was a 45% increase in the risk of being infected with an STI at follow-up (relative risk (RR) 1.45, 95% CI 1.18 to 1.78, P=0.004). Neither a decrease in closeness or commitment, nor an increase in PRSTD or PPC was associated with an STI outcome. Cumulatively, the index measure indicated that a change in an additional feeling or perception over the week increased the odds of an STI by 14% (RR 1.14, 95% CI 1.02 to 1.29, P=0.026). Conclusions A decrease in feelings of trust towards a main partner may be a more sensitive indicator of STI risk than PRSTD, PPC or commitment. The next generation of behavioural interventions for youth will need strategies to address feelings of intimacy within adolescent romantic relationships.
