Background
Stress, anxiety, and depression are prevalent among persons with rheumatic and musculoskeletal diseases (RMD), including ankylosing spondylitis, osteoarthritis, and fibromyalgia1, and impair sleep quality2. Yet, to the extent that persons with RMD foster gratitude (i.e., appreciating positive circumstances), self-compassion (i.e., self-kindness, mindfulness, and common humanity), and self-forgiveness (i.e., self-reconciliation upon admitting wrongdoing), functional impairment may be lessened via improvements in psychopathology3 and sleep4 (e.g., reduced rumination and pain catastrophizing).5,6
Hypotheses/Research Questions
We hypothesized that greater gratitude, self-compassion, and self-forgiveness would be independently related to less stress, anxiety, and depression, in parallel, and, in turn, to better sleep quality and functionality.
Sample Characteristics and Sample Size
Our sample (n=1,218) of patients with RMD, including diagnoses of ankylosing spondylitis (37%; n=434), osteoarthritis (34%; n=404), fibromyalgia (24%; n=278), and rheumatoid arthritis (14%; n=159), were primarily female (52%; n=632) and middle-aged (M=58 years; SD=11). Approximately 55% (n=673) had comorbid conditions.
Design
Participants were recruited in-person from an Austrian health facility and completed self-report measures. Bivariate correlations and serial multiple mediation regressions were conducted in R, covarying age and sex.
Results
All variables were related in expected directions (p<.01) in bivariate analyses. In multivariate analyses, positive psychological traits were related to lower stress, anxiety, and depression and, in turn, to better sleep and less impairment (gratitude: a1234d123b1234=-.012[-.015, -.008], t=-6.691; self-compassion: a1234d123b1234=-.182[-.215, -.152], t=-11.322; self-forgiveness: a1234d123b1234=-.090[-.109, -.072], t=-9.627). Each positive psychological trait explained approximately 25% of the total variance in impairment.
Scientific Contribution
Supporting hypotheses, gratitude, self-compassion, and self-forgiveness were associated with improved functionality, and psychopathology and sleep quality were mediators; that is, self-soothing positive psychological characteristics are related to improvements in both psychological and physiological health among RMD patients. Therapeutically promoting positive psychological traits (e.g., mindfulness; gratitude diaries)7,8 and reducing psychopathology and sleep problems (e.g., cognitive behavioral therapy)9,10 may improve functionality in this population.
