Social support, loneliness, eating, and activity among parent-adolescent dyads.

We examined associations of social support and loneliness with eating and activity among parent-adolescent dyads (N = 2968) using actor-partner interdependence modeling. Loneliness had several actor associations with health behaviors (adolescents: less physical activity [PA], p < .001, more sedentariness, p < .001; parents: less fruit/vegetable consumption [FVC], p = .029, more hedonic food consumption [HFC], p = .002, and sedentariness, p < .001), but only one dyadic association (adolescent loneliness with less parent FVC, p = .039). Visible support was associated with less HFC, p < .001, and sedentariness, p < .001, but less FVC, p = .008, among adolescents. Invisible support was associated with less HFC, p = .003, but also less PA, p = .028, among adolescents. Both support types were associated with less HFC among parents, p < .001, but invisible support was also associated with less FVC, p = .029, and PA, p = .012, and more sedentariness, p = .013, among parents. When examining health behavior among parents and adolescents, it may be important to consider social support (but perhaps not loneliness) at a dyadic level.

Sex Differences in the Association of Perceived Ambiguity, Cancer Fatalism, and Health-Related Self-Efficacy with Fruit and Vegetable Consumption.

Adequate fruit and vegetable (FV) consumption is promoted as a means of preventing chronic health conditions, such as cardiovascular disease and cancer. This study investigated whether perceived ambiguity about cancer prevention recommendations, fatalistic beliefs about cancer, and health-related self-efficacy were associated with FV consumption and whether sex moderated these associations. Data from the five most recent waves (spanning 2011 to 2017) of the nationally representative Health Information National Trends Survey (N = 16,965) were used. Participants reported levels of perceived ambiguity, cancer fatalism, health-related self-efficacy, and daily FV consumption. Perceived ambiguity and cancer fatalism were negatively associated with FV consumption, ps <.001, whereas health-related self-efficacy was positively associated with FV consumption, b = 0.34, p < .001. Sex moderated these associations, ps <.05. Perceived ambiguity and cancer fatalism were more strongly associated with less FV consumption for men, bs < -0.31, ps <.001, than women, bs < -0.14, ps <.01. In contrast, health-related self-efficacy was more strongly associated with more FV consumption for women, b = 0.43, p < .001, than men, b = 0.26, p < .001. These results suggest that tailoring health messaging to target sex-specific barriers may improve their effectiveness.

Associations between narrative transportation, risk perception and behaviour intentions following narrative messages about skin cancer.

OBJECTIVE: Narrative messages may be an effective strategy to increase risk perceptions and motivate preventive behaviours related to cancer. The aim of this research was to examine associations between narrative transportation (i.e. psychological absorption into a narrative), risk perceptions, and intentions following narrative messages about skin cancer. DESIGN: In two studies, women who reported indoor tanning read first-person narrative messages about skin cancer. We examined associations between narrative transportation and the women's responses to the narratives, including risk perceptions for skin cancer and behaviour intentions to reduce risk. Associations between transportation, knowledge and worry were also examined. RESULTS: Greater transportation was associated with higher intentions to perform skin self-examination, talk to one's doctor about skin cancer, and look for more information. Greater transportation was also associated with higher gut feelings of risk and higher worry about skin cancer, but not deliberative risk perceptions or knowledge from the message. Additional analyses showed that after controlling for risk perception and worry, transportation had unique associations with some behaviour intentions. CONCLUSION: Findings suggest that narrative transportation may be an important component to the persuasion of cancer narratives. Future research should explore ideas such as the role of the experiential system in narratives' influence.
