Reactance to Healthy Eating and Physical Activity Messages: Face Threat and Face Management Strategies in Memorable Daily Conversations Among Couples.

Most adults in the United States (U.S.) fail to meet guidelines for physical activity (PA) and nutrition outlined by the Centers for Disease Control. One important predictor of engagement in healthy behavior is support from one's romantic partner. However, messages from partners may fail to motivate healthy behavior if they threaten recipients' face and cause reactance. The present study examines face-threatening acts (FTAs) and face management strategies (FMSs) in conversations between romantic couples and their associations with reactance, healthy eating, and PA behaviors. Cohabitating couples ( = 70) were recruited, and one member of the couple completed a 10-day diary survey in which they reported on daily memorable conversations they had with their partner about PA and/or healthy eating. Participants completed measures of positive and negative face threat, as well as the extent to which they engaged in healthy eating and PA that day. Trained raters assessed reported conversations for positive and negative face threat as well as positive and negative FMSs. Results indicate that both participant and trained raters' reports of positive face threat were associated with increased reactance, whereas only participants' reports of negative face threat were associated with increased reactance. Both positive and negative FMSs were associated with reduced reactance. Reactance was negatively associated with healthy eating and PA. Results are discussed in terms of implications for reactance and politeness theories, as well as pragmatic implications for the millions of partnered individuals in the U.S. seeking to improve their health.
