Predictors of Coping with Health-related Expectation Violations among University Students

Abstract

Objectives: Individuals often experience expectation violations related to the consumption of healthy food and physical activity and they may cope with expectation-disconfirming information by (1) ignoring the discrepancy (immunization), (2) increasing efforts to fulfill them (assimilation), or (3) changing their expectations (accommodation). We investigated whether valence, discrepancy magnitude, and controllability of the expectation disconfirming event predicted coping with expectation violations. Methods: A 2 (valence: positive vs negative) x 2 (discrepancy: larger vs smaller) x 2 (controllability: control vs no control) experimental design was implemented. Overall, we presented 297 university students with vignettes describing expectation violations and present different combinations of predictor levels. Results: Regarding physical activity, participants showed significantly higher accommodation when experiencing a better-than-expected event and showed significantly higher immunization when experiencing a worse-than-expected event. Regarding food consumption and physical activity, individuals experiencing lower discrepancy showed significantly higher immunization; individuals with control over the source of expectation disconfirmation showed significantly higher assimilation; and individuals without control over the source of expectation disconfirmation showed significantly higher accommodation. Conclusions: To promote the maintenance of healthy expectations, despite expectation violations, interventions could foster the perception of control as well as assimilative behavior.
