The impact of subacute whiplash-associated disorders on functional self-efficacy: a cohort study

Abstract

Self-efficacy is increasingly being recognized as an important factor to consider in medical research, especially in different pain conditions such as whiplash-associated disorders (WAD). When pain is not effectively treated or relieved, it may negatively affect patients' life situation and cause a decline in perceived self-efficacy. Knowledge of what level of self-efficacy can be considered an actual deficit in patients with WAD is, however, sparse. The purpose of this study is to analyze whether subacute WAD has an impact on self-efficacy beliefs. A cohort study was designed to identify the impact of WAD on self-efficacy beliefs. The exposed group consisted of 47 patients with subacute WAD following a whiplash trauma. The control group representing the general population consisted of 212 participants, and was randomly selected to match the distribution of age and sex in the exposed group. The Self-Efficacy Scale was used to assess the individuals' confidence in their ability to successfully carry out activities of daily living. In the exposed group, 47 responded (100%), and in the control group, 113 (53%) responded. The results show that the total scores on the Self-Efficacy Scale were significantly lower in the exposed group compared with the control group, concerning both the mean (P<0.001) and median (P<0.001) scores. In conclusion, patients with subacute WAD experience a decline in functional self-efficacy, which stresses the importance of incorporating these beliefs in clinical practice and research.
