Background: Parkinson's disease (PD) brings with it a range of stresses and challenges with which a patient must cope. The type of coping strategies employed can impact upon well-being, although findings from coping studies in PD remain inconsistent. The variety of coping scales used without validation in PD has been cited as a possible cause of this inconsistency. The present study sought to examine the validity of the coping inventory for stressful situations (CISS) in a sample of patients with PD. Methods: Five hundred and twenty-five patients with PD were recruited as part of a longitudinal investigation of mood states in PD. Four hundred and seventy-one participants completed the CISS. Confirmatory factor analysis was used to explore the structural validity of the scale. Internal reliability, test-retest reliability, convergent validity and discriminant validity were assessed using Cronbach's alpha, intraclass correlations and Pearson's correlations. Results: Both three and four factor solutions were examined. The four factor model was found to provide a better fit of the data than the three factor model. The internal reliability, discriminant validity, convergent validity, and test-retest reliability of the CISS scales were shown to be good. Use of emotion-focused coping was associated with greater depression and anxiety whilst, task-oriented coping was associated with better psychological well-being. Conclusion: The results provide support for the validity and reliability of the CISS as a measure of coping in patients with PD. Further research into the relationship between coping and well-being is warranted. The identification of helpful and unhelpful coping strategies may guide the development of evidence-based therapies to improve well-being in patients with PD.
