Abstract

Objectives

Fibromyalgia (FM) has been associated with a higher prevalence of suicidal behavior. Nevertheless, much remains unknown about suicide risk factors for this chronic pain disorder. In the present study, the relationship of suicidal ideation in FM with a number of sociodemographic, clinical, and psychological variables was analyzed.

Methods

One hundred seventeen women with Fibromyalgia were assessed. The procedure included the exploration of sleep problems (Pittsburgh Sleep Quality Index), depression (Beck Depression Inventory [BDI]), health-related quality of life (SF-36 and Fibromyalgia Impact Questionnaire), the core symptoms of FM (visual analogue scales), and algometry of tender points. Suicidal ideation was evaluated by item 9 of the BDI. Patients with presence vs. absence of suicidal ideation were compared in all the variables studied.

Results

The prevalence of suicidal ideation among FM patients was 32.5%. Significant differences between patients with vs. without suicidal ideas emerged mainly for the various indices of depression. Patients with suicidal ideation also reported higher levels of anxiety, more day dysfunction due to sleepiness and more limitations due to emotional and physical problems. Logistic regression analysis revealed that cognitive depression symptoms such as BDI Self-Blame cluster are the more closely related to suicide ideation.

Conclusions

The presence of suicidal ideation in FM patients is closely related to comorbid depression, anxiety and to a higher impact of the disease in daily life.
