PURPOSE
Psychological factors have shown to be associated with treatment outcomes in hand injury patients. This study aimed to investigate the role of health locus of control (HLOC) and its dimensions internal, social-external, and fatalistic-external HLOC in treatment outcomes of hand injury patients.
METHOD
One hundred thirty-two consecutive patients of a tertiary center for hand surgery undergoing treatment for acute hand injury or degenerative hand problems were included in this study. Pretreatment levels of depression, anxiety, HLOC, and pain intensity were measured, along with pain intensity levels at 4-month follow-up. Hierarchical regression analyses were calculated to test for moderation effects of the HLOC dimensions on the relationship between pretreatment and follow-up pain intensity.
RESULTS
Controlling for age, gender, treatment modality, source of hand pain, and depressive symptoms, a moderation effect emerged (β = - 0.16, p < 0.05), such that among patients higher in initial pain intensity, those lower in social-external HLOC experienced higher pain intensity at follow-up compared to those with high social-external HLOC. Internal HLOC and fatalistic-external HLOC did not moderate the effect of initial pain intensity on pain intensity at follow-up.
CONCLUSION
Hand injury patients suffering greater initial pain intensity who also had lower versus higher social-external HLOC experienced less favorable treatment outcome. This finding suggests that if patients with high initial pain succeed in transferring perceived health control to professionals and to gain confidence in treatment and clinicians, treatment outcome could be improved in hand surgery.
