Aim: This study aimed to investigate psychiatric disorders in Iranian female patients with fibromyalgia (FM).
Design: Female patients, newly diagnosed with FM, were interviewed by a psychiatrist for psychiatric assessments during a 2-year period.
Methods: The diagnosis of the psychiatric disorders was based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI).
Results: In total, 159 patients with the mean age of 42.15 ± 9.89 were recruited in this study. Over 92% of the cases were also diagnosed with at least one type of psychiatric disorder. Sleep disorders (SDs, 90.57%), mood disorders (MDs, 52.83%), personality disorders (PDs, 40.25%) and anxiety disorders (ADs, 16.98%) were the most prevalent diagnoses among these patients. The logistic regression results correspondingly showed that suffering from Cluster-B PDs was associated with a higher prevalence rate of somatic symptom disorders (SSDs), with a p-value of 0.019 and an odds ratio (OR) of 2.7.
