Description: A repeated measures correlational design was used to investigate the relationships between uncertainty and coping following coronary artery bypass surgery (CABS) in a sample of 129 men and women, using Mishel's Model of Uncertainty in Illness. The Revised Ways of Coping Checklist and the Mishel Uncertainty in Illness Scale were completed between 5 and 10 days following CABS (Survey 1) and at 6 weeks following CABS (Survey 2).

There were no relationships between the ambiguity and complexity factors of uncertainty and problem-focused coping for Survey 1. For Survey 2, ambiguity was positively related to problem-focused coping, explaining 5% of the variance. The canonical correlations between the uncertainty factors ambiguity and complexity, and the emotion-focused coping strategies, avoidance, blamed-self and wishful thinking, for Survey 1 and 2, were.45 and.49, respectively. Ambiguity was the significant correlate of wishful thinking and avoidance coping for Survey 1. For Survey 2, the combination of ambiguity and complexity explained the variance in wishful thinking and avoidance coping.

There were no relationships between ambiguity and complexity and seeks social support coping for Survey 2. Ambiguity was positively related to seeks social support coping for Survey 2, explaining 5% of the variance. Use of problem-focused coping did not change between Survey 1 and 2, while seeks social support coping decreased. Multivariate analysis of variance for repeated measures demonstrated an overall change in emotion-focused coping strategies (avoidance, blamed-self, and wishful thinking) between Survey 1 and 2. Only the decreases in blamed-self and avoidance coping were statistically significant. There was an overall change in uncertainty. Complexity increased significantly; and there was no significant change in ambiguity.

Replication of these analyses in sub-samples of younger (age 38 to 64) and older (age 64 to 78) persons revealed differences in the relationships among these variables between the two groups.

Findings support the positive relationship between uncertainty and emotion-focused coping and the need for further investigation of the relationships between uncertainty and problem-focused and seeks social support coping. Further investigation of the relationships between uncertainty and coping in older persons is recommended.
