Do Psychological Factors Explain the Persistence of Symptoms in Individuals With Rotator Cuff-related Shoulder Pain? A Prospective Cohort Study.

Objective: To determine whether psychosocial factors, such as resilience, perceived stress, catastrophizing, anxiety, depression, pain self-efficacy, and social support, explain the persistence of pain and disability in individuals with rotator cuff-related shoulder pain (RCRSP) following an education program.

Methods: One hundred forty-three individuals with persistent RCRSP were included in this prospective cohort study. At baseline, participants completed self-reported questionnaires related to pain, disability, and psychosocial constructs, including resilience, stress, catastrophizing, anxiety and depressive symptoms, pain self-efficacy, and social support. Thereafter, participants took part in an educational program aimed at promoting self-management of RCRSP that included 2 meetings with a physiotherapist. After 12 and 24 weeks, participants filled out pain and disability questionnaires and, based on their scores, were classified as having persistent shoulder pain or as recovered.

Results: A univariable modified Poisson regression showed that higher perceived stress (RR adjusted : 1.02; 95% CI: 1.01-1.04), catastrophizing (RR adjusted : 1.01; 95% CI: 1.01-1.02), symptoms of depression (RR adjusted : 1.03; 95% CI: 1.01-1.06) and anxiety (RR adjusted : 1.03; 95% CI: 1.01-1.06), along with lower resilience (RR adjusted : 0.90; 95% CI: 0.81-1.00), were associated with ongoing RCRSP at 12 weeks. In addition, reduced pain self-efficacy was associated with persistent pain at both 12 weeks (RR adjusted : 0.98; 95% CI: 0.97-0.99) and 24 weeks (RR adjusted : 0.99; 95% CI: 0.98-1.00). Multivariable regression indicated that only pain self-efficacy served as a protective factor against persistent RCRSP (RR adjusted : 0.98; 95% CI: 0.97-0.99).

Discussion: This study sheds light on the impact of psychosocial factors on persistent RCRSP, underscoring the importance of positive beliefs in pain management. Importantly, pain self-efficacy emerges as a key factor in recovery.
