Why is it so hard to change? The role of self-integrity threat and affirmation in weight loss

People are frequently dissatisfied with their body weight. Messages alleging that lower weight is esthetically preferable, healthier, and achievable likely trigger chronic self-integrity threat, the sense that one's personal adequacy is in doubt. We examined whether self-integrity threat, which creates stress and pressure to restore self-integrity, contributes to the challenges of weight and behavior change. Weight-dissatisfied women completed in-lab tasks including a values affirmation manipulation and two-month follow-up. Affirmed women lost weight relative to controls, replicating previous research. Effects were primarily among those with higher initial body masses. Affirmed higher-weighted women also ate more healthful foods compared to unhealthful foods in self-reports and observation. Affirmed participants reported increased exercise, and an exploratory measure showed that their cortisol awakening responses synchronized with their coping needs, suggesting more adaptive physiological function. Results suggest that self-integrity threat is an under-recognized barrier to change, and reducing it can support healthy changes.     

Stress experience and performance during an oral exam: the role of self-efficacy,threat appraisals,anxiety, and cortisol

Background and Objectives: High self-efficacy may reduce emotional and physiological stress responses in the context of an examination. The present study investigated how these stress responses develop on an exam day, and sequential indirect effects between self-efficacy, threat appraisals, stress responses and performance.

Design and Methods: The sample comprised 92 students (46 women). Self-efficacy, threat appraisals and state anxiety were assessed on a control day one week before an oral exam. Additionally, anxiety was assessed three times on the exam day. Salivary cortisol samples were collected at all time points.

Results: Pre-exam anxiety and cortisol decreased until grades were announced. For both responses, greater levels were related to a steeper decline. However, changes in anxiety and cortisol were unrelated. Self-efficacy was negatively related to threat appraisals and anxiety on the control day. Greater threat appraisals were associated with higher pre-exam anxiety and a steeper anxiety decrease on the exam day, which in turn, was related to better performance.

Conclusions: High levels of self-efficacy may reduce threat appraisals and anxiety in the lead up to an exam, which are related to the intensity and decline of anxiety on the exam day. A steeper decline of anxiety may be beneficial to performance.
