Abstract

BACKGROUND: Generalized anxiety disorder (GAD) and chronic pain conditions commonly co-occur, and are both independently associated with suicidality; however, little is known about the impact of chronic pain on suicidality among individuals with GAD. The aim of this study was to examine the associations between comorbid GAD and chronic pain conditions with suicide ideation, plans, and attempts in a population-based sample.

METHODS: We analyzed data from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH; N = 25,113). Multiple logistic regressions examined the associations between comorbid GAD and chronic pain conditions (i.e., arthritis, migraine, back pain; reference = GAD alone) with suicidality (i.e., ideation, plans, and attempts).

RESULTS: After adjusting for sociodemographics, other psychiatric conditions, and other chronic pain conditions, results indicated that compared to GAD alone, comorbid GAD and migraine was associated with increased odds of suicide ideation and plans (adjusted odds ratio (AOR) range: 2.55-3.00) and comorbid GAD and arthritis was associated with increased odds of suicide attempts (AOR = 4.10, 95% CI [1.05-16.01]). LIMITATIONS: The cross-sectional nature of the survey design does not permit causal assumptions regarding the emergent associations and the self-report assessment of chronic pain conditions may be associated with response biases.

CONCLUSIONS: Results highlight the burden of chronic pain on suicidality among individuals with GAD. These results emphasize the importance of assessing risk of suicidality among individuals with comorbid GAD and chronic pain conditions, particularly migraine and arthritis.
