Relationship Between Attitudes and Beliefs About Sleep, Sleep Disturbance, and Pain Interference in Patients With Spinal Pain.

OBJECTIVES: Sleep impairments are a strong predictor of pain, making sleep a potential interest when treating patients with spine pain. Typical beliefs about the importance of sleep in patients seeking care for spinal pain are unknown. The purpose of this study was to describe the beliefs and attitudes about sleep in patients seeking care for spinal pain and to examine the relationships between dysfunctional beliefs and attitudes about sleep (DBAS), disordered sleep, and pain interference. MATERIALS AND METHODS: This cross-sectional study included patients presenting to physical therapy with spine pain. Participants completed questionnaires including demographics, medical history, pain interference (pain, enjoyment, and general activity), DBAS-16, and sleep-related impairment (Patient-Reported Outcome Measurement Information System). Correlations were calculated between DBAS-16 scores and measures of sleep quality/quantity, and a generalized linear model was used to investigate the predictive ability of DBAS-16 scores on pain interference. RESULTS: The mean DBAS-16 score was 4.22 (SD=2.03), with 52.5% of participants having DBAS. There was a strong relationship between DBAS-16 and Patient-Reported Outcome Measurement Information System ( rs =0.7; P <0.001). For every point higher score on the DBAS-16, pain interference scores increased by approximately half a point (B=0.46; 95% CI 0.33, 0.59, 1.80; P <0.001). DISCUSSION: These results highlight a strong relationship between beliefs and attitudes about sleep and measures of sleep quality/quantity and a linear association with pain interference scores. These findings provide a rationale for targeting beliefs and attitudes about sleep when managing pain-related symptoms in patients seeking care for spine pain.
