title: Disease controllability moderates the effect of coping efficacy on positive affect.
abstract: OBJECTIVE
  This study aims to test experimentally whether coping strategies (approach- vs. avoidance-oriented coping) have differential effects under conditions of high or low stressor controllability.
  
  
  METHODS
  Undergraduates (62 women, 30 men) participated in a 2 × 2 experimental study where they were introduced to a fictitious disease (tisomerase enzyme deficiency) said to be either controllable or uncontrollable and an approach- or avoidance-oriented coping behaviour induction.
  
  
  METHODS
  Changes in positive and negative affect.
  
  
  RESULTS
  A significant disease control x coping interaction on positive affect (f(2) = .07, p = .011) revealed that approach-coping condition participants had higher positive affect than avoidance-coping condition participants when disease control was high (d = .94, p = .003), but not when it was low (d = .11, p = .93). The experimental conditions did not significantly influence negative affect.
  
  
  CONCLUSIONS
  Results demonstrate that disease control moderates the salubrious effects of approach-oriented coping on positive affect. For controllable, but not uncontrollable, health stressors, promoting problem-focused approach-oriented coping strategies may be recommended.
