THE TOTALITARIAN STATE OF MIND

The paper describes the development of Dynamic Interpersonal Therapy for use with complex depression (DITCC), and a pilot study testing DITCC’s effectiveness. The pilot found large pre-post improvements in well-being and distress; moderate rates of reliable improvement and clinically significant change; and curvilinear declines in depression and anxiety. Treatment completers and near-completers (N= 19) showed a significant curvilinear decline in symptoms of depression (PHQ-9) and anxiety (GAD-7). The results provide preliminary evidence that DITCC can be used as an effective treatment approach for complex depression. However, further research is needed to test its effectiveness in different settings with a larger sample size, using appropriate comparison groups under controlled conditions to further elaborate the short-term and long-term effects.     

Interpersonal feedback in everyday life: Empirical studies in Germany and the United States

The present research examines occurrences of interpersonal feedback in everyday life. Drawing upon retrospective self-reports from three student samples in Germany and the US, we investigate why, how, and with what effect such feedback is shared. We found that feedback was common, occurring mostly within stable interpersonal relationships, and that positive feedback was reported to occur more often than negative feedback. Positive and negative feedback was provided to achieve different goals (acknowledgement vs. behavioral change), and feedback senders perceived negative feedback as less successful than positive feedback. Negative feedback was withheld primarily when potential senders perceived it as futile or potentially dangerous to their relationship with the recipient. However, negative feedback that was shared was not seen as particularly harmful in that regard. We discuss potential barriers to feedback effectiveness, whether and how the exchange of interpersonal feedback in everyday life may be promoted, and give recommendations for future research.     

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.
