Abstract

This study aimed to adapt the Diagnostic Criteria for Psychosomatic Research-Revised Semi-Structured Interview (DCPR-R-SSI) into Turkish and assess its psychometric properties.
This study was conducted with two separate samples of patients diagnosed with psychosomatic disorders between the ages of 18-65 at Gazi University Psychiatry Clinic. For inter-rater reliability analysis, a sample of 100 participants was evaluated by two raters and kappa coefficient was calculated. Validity analysis used samples from both patient and community groups. For criterion validity, the relationship between DCPR diagnoses and the Hospital Anxiety Depression Scale (HADS), Patient Health Questionnaire 15 (PHQ- 15), Health Anxiety Inventory (HAI) and Toronto Alexithymia Scale (TAS) was analyzed with the Point Biserial Correlation Coefficient. The distribution of DCPR diagnoses in the community and hospital samples was analyzed.
The mean age of the sample for inter-rater reliability analysis was 33.5±13.0 years and 55% were female. Kappa values for 14 DCPR-R diagnoses were between 0.823-0.964. The hospital and community samples included 110 people from the community and 100 from the hospital. In the validity analyses, Allostatic Overload showed a significant relationship with HADS-Depression, HADS-Anxiety, PHQ-15 and HAI. Demoralization and Demoralization with Hopelessness showed a significant relationship with all scales. Type A Behavior was weakly correlated with all scales, whereas Alexithymia was strongly correlated with the TAS. The five most common DCPR-R diagnoses were Allostatic Overload (55.2%), Demoralization (36.1%), Alexithymia (29.0%), Type A Behavior (27.6%), Irritable Mood (15.7%), Persistent Somatization (11.9%) and Health Anxiety (10.9%).
This study demonstrated that the Turkish version of DCPR-R is a valid and reliable measurement tool.
