The relationship between perfectionism and engagement in preventive health behaviours: the mediating role of self-concealment.

If perfectionists avoid engaging in preventive health behaviours, they may be putting their long-term health and well-being at risk. Correlational analyses based on a sample of 370 university students identified maladaptive perfectionism to be associated with decreased levels of engagement in preventive health behaviours, life satisfaction and well-being and increased levels of self-concealment and psychological distress. Adaptive perfectionism was associated with higher levels of engagement in preventive health behaviours. Self-concealment was identified as a partial mediator in the relationship between maladaptive perfectionism and both engagement in preventive health behaviours and psychological distress. Implications of the findings are discussed.
