Self-efficacy as a health-protective resource in teachers? A biopsychological approach

OBJECTIVE: To examine the psychobiological correlates of self-efficacy in teachers. DESIGN: Study 1 examined associations between teacher self-efficacy and cardiac activation on a working day and Study 2 assessed the cortisol morning response in teachers with varying levels of teacher self-efficacy. MAIN OUTCOME MEASURES: Teacher self-efficacy was assessed by questionnaire. In Study 1 heart rate, heart rate variability, and locomotor activity were recorded by 22 hours ambulatory monitoring and subjective measures of stress and strain were obtained. Study 2 assessed the cortisol response to awakening to obtain a measure of HPA-axis activation and teachers filled in a questionnaire on physical complaints. RESULTS AND CONCLUSION: Study 1 found that self-efficacy proved protective for psychological well-being. Moreover, after controlling for locomotor activity, demographic, and lifestyle variables, self-efficacy was associated with elevated heart rate and attenuated heart rate variability during school and leisure time, respectively, but not during the night, thus questioning the health-implications of self-efficacy. Study 2 found that teachers high in self-efficacy exhibited an attenuated cortisol response to awakening and fewer cardiac complaints. The results of both studies are compatible with the view that teacher self-efficacy might act as a physiological toughening agent with possibly favorable health outcomes.
