Marital adjustment in patients with fibromyalgia: its association with suicidal ideation and related factors. A cross-sectional study

Objective. Fibromyalgia has been associated with suicidal ideation, suicide attempts and completed suicide. Non-married status is a risk factor for suicidal behaviours but the quality of the marital relationship has been scarcely investigated. The objectives of the present study were to evaluate, in patients with fibromyalgia, the relationship between marital adjustment suicidal ideation and potentially related variables: depression severity, sleep disturbance, perceived burdensomeness, thwarted belongingness, fibromyalgia severity and pain intensity. Methods. A survey was done in patients with fibromyalgia which collected sociodemographic data and included the following questionnaires: the Locke and Wallace Marital Adjustment Test, the Beck's Depression Inventory II, the Plutchik Suicide Risk Scale, a 10-item version of the Interpersonal Needs Questionnaire, the Insomnia Severity Index, and the Revised Fibromyalgia Impact Questionnaire. Suicidal ideation was assessed with item 9 of the Beck's Depression Inventory, and pain intensity was measured with the VAS scale of the Revised Fibromyalgia Impact Questionnaire. Results. Of 257 participants 71 were single, 107 had a good marital adjustment and 79 a poor marital adjustment. Suicidal ideation was most frequent among patients with poor marital adjustment than among those with good marital adjustment or patients without partner. The poor marital adjustment group showed significantly worse scores in most of the remaining variables with the only exceptions of the FIQR and pain scores. Conclusion. In patients with fibromyalgia the degree of marital adjustment seems to be a relevant factor for suicidal ideation and related variables.
