Interpersonal effects of parents and adolescents on each other’s health behaviours: a dyadic extension of the theory of planned behaviour

Objective: Interpersonal relationships are important predictors of health outcomes and interpersonal influences on behaviours may be key mechanisms underlying such effects. Most health behaviour theories focus on intrapersonal factors and may not adequately account for interpersonal influences. We evaluate a dyadic extension of the Theory of Planned Behaviour by examining whether parent and adolescent characteristics (attitudes, subjective norms, perceived behavioural control and intentions) are associated with not only their own but also each other’s intentions/behaviours.

Design: Using the Actor-Partner Interdependence Model, we analyse responses from 1717 parent-adolescent dyads from the Family Life, Activity, Sun, Health, and Eating study.

Main Outcome Measures: Adolescents/parents completed self-reports of their fruit and vegetable consumption, junk food and sugary drinks consumption, engagement in physical activity, and engagement in screen time sedentary behaviours.

Results: Parent/adolescent characteristics are associated with each other’s health-relevant intentions/behaviours above the effects of individuals’ own characteristics on their own behaviours. Parent/adolescent characteristics covary with each other’s outcomes with similar strength, but parent characteristics more strongly relate to adolescent intentions, whereas adolescent characteristics more strongly relate to parent behaviours.

Conclusions: Parents and adolescents may bidirectionally influence each other’s health intentions/behaviours. This highlights the importance of dyadic models of health behaviour and suggests intervention targets.     

Explaining social contagion in sport applying Heider's balance theory: First experimental results

A sudden collective collapse of an entire sport team is often described in terms of the social contagion of weak performance. Two experiments studied this phenomenon against the backdrop of balance theory. Experiment 1 examined whether false negative feedback on a partner's performance during a team task would lead to compensatory mechanisms as predicted by balance theory. Results showed that perceived negative performance in the partner was compensated by devaluing the relationship to the partner. Experiment 2 replicated Experiment 1 and investigated the impact of physical self-esteem. Results showed that persons with strong physical self-esteem devalued the situational value of the relationship when they perceived their partner's performance to be negative. Experiment 2 also investigated objective performance. Although failing to attain statistical significance, there was a tendency for the perceived sudden decline in the partner's performance to be contagious. It is concluded that balance theory offers promising insights into the interpersonal dynamics of social contagion.     

Success with a twinge of distress: Antecedents and consequences of outperformance-related discomfort

Although outperforming others brings intrapersonal benefits, it may also carry interpersonal costs. The term Sensitivity about being the Target of a Threatening Upward Comparison (STTUC) captures the discomfort that outperformers may feel when they perceive that their success upsets an outperformed person. This paper reviews 20+ years of research on STTUC. It begins by defining STTUC and its three essential criteria. It then delineates situation and person variables that explain variability in STTUC. It follows by describing outperformers' varied reactions to STTUC and then explains the potential social function of STTUC.     

Blurring the Dichotomy of Good and Evil: The Idiosyncratic Helping Strategies Associated with Unmitigated‐Agentic and Unmitigated‐Communal Personalities

We theorized that unmitigated‐agentic personality constructs (UAPs)—prioritizing 'getting ahead’ over 'getting along’—and unmitigated‐communal personality constructs (UCPs)—prioritizing getting along over getting ahead—are associated with distinct affect‐regulatory helping strategies. In Study 1 (N = 179), UAPs, on average, related to greater negative‐affect versus positive‐affect induction helping tactics. In two experiments, UAPs, on average, related to a greater likelihood of selecting anger‐inducing versus love‐inducing or sadness‐inducing songs to help a target overcome a breakup (Study 2; N = 313) and greater selection of anger‐inducing and hubris‐inducing messages versus authentic‐pride‐inducing and love‐inducing messages to help a teammate struggling in a game (Study 3; N = 246). UCPs manifested the opposite patterns. Generally, these associations corresponded with helping‐strategy utility beliefs and were robust to moderators of helping target (self or other; Study 2) or altruistic versus selfish motives (Study 3). Study 4 (N = 205) provided some evidence of ecological validity in contexts of recalled everyday helping. Associations between personality constructs and relative helping strategies were about moderate in size (rs ~ .20) across these four studies. Findings suggest that UAPs are associated with helping strategies believed to promote ‘contemptuous’ self‐enhancement relative to ‘innocuous’ self‐enhancement and self‐transcendence, and vice versa for UCPs. © 2019 European Association of Personality Psychology
