Objective: To investigate the relationship of the patient’s criteria of successful treatment to emotional factors in patients with chronic musculoskeletal pain.
Methods: Patients who visited our outpatient hospital due to chronic musculoskeletal pain were evaluated using a questionnaire survey. Patients were evaluated with the Patient-Centered Outcomes Questionnaire (PCOQ) to investigate their expectation and criteria for success regarding treatment of chronic musculoskeletal pain. Beck Depression Inventory and State-Trait Anxiety Inventory were used to check for psychological variables. Correlations among each of the variables were evaluated statistically.
Results: Patients with higher levels of depression and anxiety needed larger improvements to consider the treatment as a success in the pain domain (depression, r=0.398, p=0.04; anxiety, r=0.447, p=0.02) and emotional distress domain (depression, r=0.617, p=0.001; anxiety, r=0.415, p=0.03), but had lower level of expectation of the treatment in the pain domain (depression, r=-0.427, p=0.01; anxiety, r=-0.441, p=0.004), emotional distress domain (depression, r=-0.454, p=0.01; anxiety, r=-0.395, p=0.04), and interference of daily activities domain (depression, r=-0.474, p=0.01; anxiety, r=-0.396, p=0.04). Patients were classified into 3 clusters based on the importance rating of each domain via a hierarchical analysis. The cluster of the patients with the higher rating of importance across all domains (importance of pain domain, 9.54; fatigue domain, 9.08; emotional distress domain, 9.23; interference of daily activities domain, 9.23) had the highest level of depression and anxiety.
Conclusion: Consideration of psychological factors, especially in patients who require larger improvements in all treatment domains, may be helpful for the successful treatment of chronic musculoskeletal pain.
