In systemic sclerosis, anxiety and depression assessed by hospital anxiety depression scale are independently associated with disability and psychological factors.

BACKGROUND: Anxious and depressive symptoms are frequent in Systemic Sclerosis (SSc). Our objective is to assess their prevalence and association with district and global disability and psychological variables. METHODS: 119 SSc patients were assessed by Hospital Anxiety Depression Scale (HADS). Clinical depression and anxiety were defined for HADS score cutoff ≥ 8. Patients were assessed for psychological symptoms (RSES, COPE-NIV), hand (HAMIS, CHFDS, fist closure, and hand opening) and face disability (MHISS, mouth opening), global disability, and fatigue (HAQ, FACIT). RESULTS: Both depression and anxiety in SSc are 36%. Depressive patients with comorbid anxiety have higher HADS-D score than patients with depression only (P = 0.001). HADS-A and -D are positively correlated with global disability, hands and mouth disability, fatigue, self-esteem and avoidance coping strategy, and, only HADS-A, also with social support (P < 0.05). By multiple regression, HADS-D is independently associated with FACIT-F (P < 0.001), RSES (P < 0.001), and MHISS total score (P = 0.016), together explaining 50% of variance. HADS-A is independently associated with RSES (P = 0.006), COPE-NIV SA (P = 0.003), COPE-NIV SS (P = 0.008), FACIT-F (P = 0.022), and MHISS mouth opening (P = 0.029), explaining 41% of variance. CONCLUSIONS: In SSc depression and anxiety correlate to local and global disabilities and psychological characteristics. Depressive patients with comorbid anxiety have higher level of depressive symptoms.
