RESUMO
OBJECTIVE: The study aimed at determining the experience of pain taking into consideration beliefs about pain control, Type A behavior pattern and sociodemographic factors in patients with chronic ischemia of the lower extremities or with rheumatoid arthritis (RA). METHODS: The study enrolled 100 patients with peripheral arterial disease (PAD) and 100 patients with RA. The subjective sensation of pain was assessed using the Visual Analog Scale (VAS); beliefs about pain control were analyzed using the Beliefs about Pain Control Questionnaire (BPCQ), taking into consideration internal factors, the influence of physicians and accidental events (chance); and Type A behavior features (haste and competition) were analyzed using the Framingham Type A Scale. The multiple regression model was used to assess associations between the experienced pain and the BPCQ value, the Framingham Type A Scale and sociodemographic factors. RESULTS: The pain intensity degree was found to be comparable in patients with PAD and with RA. The median determined using the VAS was 5.75 in both of the studied groups. In patients with PAD, lower VAS values were associated with the BPCQ - internal factors (P<0.05) whereas a higher VAS value was related to the BPCQ - physicians' influence (P<0.001). In patients with RA, a higher VAS value was associated with BPCQ - physicians' influence (P<0.05), disease duration (P<0.05) and smoking cigarettes (P<0.05). CONCLUSION: Experiencing pain by patients with chronic ischemia of the lower extremities occurs at a moderate level and is beneficially connected with the internal factors and adversely connected with the external factors of beliefs about pain control. Patients with RA reported pain ailments of a moderate level in connection with the adverse influence of the external factors of beliefs about pain control, the duration of the disease and smoking cigarettes. Experiencing pain by patients with chronic ischemia of the lower extremities and RA does not seem to be related to Type A behavior.
