Temperament and character dimensions of personality in patients with chronic pain disorders

Abstract

Objective: It is known that a complex relationship is present between chronic pain and personality. In this study, weaimed to compare the clinical features and personality traits of patients with Chronic Pain Disorder (CPD) and healthycontrols. We hypothesized that Harm Avoidance (HA) scores would be higher and predictive of compared to healthycontrols.Methods: This study was conducted in outpatients with CPD who presented to the Bagcilar Training and ResearchHospital's Outpatient Psychiatry Clinic. The sample was comprised of 60 outpatients (53 women, 7 men) who complainedof chronic pain for at least 3 months and were not under any medication treatments. The control group comprised of60 healthy controls (49 women, 11 men). Semi-structured sociodemographic data form, Visual Analog Scale (VAS),Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI)were administered to the participants. All statistical analyses were performed using SPSS for Windows, Version 23.0.Results: Impulsiveness subscale of Novelty Seeking; Harm Avoidance and its subscales of Anticipatory worry, Fearof uncertainty, Shyness with strangers, and Fatigability and asthenia scores were significantly higher in CPD patientscompared to the control group. Harm Avoidance and its subscales of Anticipatory worry, Fear of uncertainty, Shynesswith strangers, and Fatigability and asthenia scores were significantly positively correlated with the BDI, BAI, and VASscores. When VAS scores were entered as the dependent variable and age and gender were controlled in regressionanalysis, Harm Avoidance was significantly predictive of VAS scores.Conclusion: Temperament and character traits of the CPD patients were significantly different from the healthy controlsubjects. HA scores were higher and predictive of CPD compared to healthy controls.
