Background The use of maladaptive coping strategies in patients with rheumatoid arthritis (RA) associates with disability, psychological distress and high pain intensity. Identifying the predictors of maladaptive coping could help physicians in revealing the target group of patients which requires the conducting of the cognitive - behavioral therapy.
Objectives To identify the predictors of maladaptive coping strategies in patients with RA.
Methods The cross-sectional survey included 124 patients with RA (male to female ratio 4,4:1), mean age 49,4 [44; 56] years, mean duration of disease ranged from 3 months to 41 years (10,8 [3,5;13]). RA diagnosis based on ACR/EULAR criteria of 2010. Patients completed the following questionnaires: Visual - Analogue Scale (VAS), Beck Depression Inventory, State-Trait Anxiety Inventory, McGill Pain Questionnaire, The Pain Catastrophizing Scale. To identify the predictors of maladaptive strategies a logistic regression model was constructed (R2=0,694, p<0,001, β – is a standard indicator characterizing the strength of variable influence).
Results Among the clinical parameters that significantly influenced to the choice of patients were the level of pain intensity (β=0,4), frequency of NSAID use (β =0,2), disability index (β=0, 6), disease duration (β= -0,3), the duration of morning stiffness (β= -0,3), the presence of systemic manifestations (β =-0,3), pain catastrophizing level (β=0,5), depression (β= -0.2), erythrocyte sedimentation rate (ESR) (β= -0,2), severe pain registers (β=1,2) and a large amount of descriptors (β= -1) selected on McGill Pain Questionnaire.
Conclusions The intensity of pain, frequency of NSAID use, RA duration, the duration of morning stiffness, the presence of systemic manifestations along with the ESR, level of catastrophizing, depression, severe registers of pain intensity and a large amount of pain descriptors were significant predictors of maladaptive coping in patients with RA. The findings could provide an opportunity to distinguish the target group of patients with RA, who needs along with the standard therapy of RA the conducting of cognitive - behavioral therapy.
