Distress and Factors Associated with Suicidal Ideation in Veterans Living with Cancer

Fed Pract. 2020 May;37(2):S8-S15

Author(s):

Backgrounds and Objectives: Eliminating veteran suicide is a top priority for the US Department of Veterans Affairs (VA). Veterans with cancer may be at particular risk for suicidal ideation (SI). The current study aimed to understand factors associated with distress in veterans with cancer who were referred for psychology services, and identify problems associated with SI.

Methods: Health records of veterans with cancer (N = 174) were reviewed to abstract data, including results of National Comprehensive Cancer Network (NCCN) Distress Thermometer and Problems List and clinical suicide risk assessments.

Results: Veterans with severe distress were significantly more likely to endorse SI and have a history of suicide attempt(s) when compared with veterans with mild or moderate distress ( χ ² = 18.36, P < .001). Of the problems endorsed on the NCCN Problems List, family problems were most strongly linked to SI ( χ ² = 5.54, degrees of freedom [ df ] = 1, P = .02). Specifically, veterans who endorsed problems with their partner were 5 times more likely to experience SI when compared with veterans who did not endorse this problem (Wald = 15.142; df = 1, P < .001).

Conclusions: This study is among the first to find partner problems as a suicide risk factor for veterans with cancer; and, underscore the importance of assessing for partner problems and suicidal ideation among veterans with cancer. This study supports the VA mission to end veteran suicide and addresses a gap in current literature by investigating the understudied population of veterans living with cancer and risk factors for SI.

It was estimated that physicians would diagnose a form of invasive cancer > 1.7 million times in 2019. As the second most common cause of death in the US, > 600,000 people were projected to die from cancer in 2019.¹Many individuals with cancer endure distress, which the National Comprehensive Cancer Network (NCCN) defines as a “multifactorial unpleasant experience of a psychological (ie, cognitive, behavioral, emotional), social, spiritual, and/or physical nature that may interfere with the ability to cope effectively with cancer, its physical symptoms, and its treatment.”^2,3 Distress in people living with cancer has been attributed to various psychosocial concerns, such as family problems, whichinclude dealing with partners and children; emotional problems, such as depression and anxiety; and physical symptoms, such as pain and fatigue.^4-9 Certain factors associated with distress may increase a patient’s risk for suicide.⁴

Veterans are at particularly high risk for suicide.¹⁰ In 2014, veterans accounted for 18% of completed suicides in the US but only were 8.5% of the total population that same year.¹⁰ Yet, little research has been done on the relationship between distress and suicide in veterans living with cancer. Aboumrad and colleagues found that 45% of veterans with cancer who completed suicide reported family issues and 41% endorsed chronic pain.¹¹ This study recommended continued efforts to assess and treat distress to lessen risk of suicide in veterans living with cancer; however, to date, only 1 study has specifically evaluated distress and problems endorsed among veterans living with cancer.⁷

Suicide prevention is of the highest priority to the US Department of Veterans Affairs (VA).¹² Consistent with the VA mission to end veteran suicide, the current study aimed to better understand the relationship between distress and suicide within a sample of veterans living with cancer. Findings would additionally be used to tailor clinical assessments and interventions for veterans living with cancer.

This study had 3 primary goals. First, we sought to understand demographic and clinical factors associated with low, moderate, and severe levels of distress in veterans living with cancer who were referred for psychology services. Second, the study investigated the most commonly endorsed problems by veterans living with cancer. Finally, we examined which problems were related to suicidal ideation (SI). It was hypothesized that veterans who reported severe distress would be significantly more likely to endorse SI when compared with veterans who reported mild or moderate distress. Based on existing literature, it was further hypothesized that family, emotional, and physical problems would be significantly associated with SI.^7,11

Methods

The current study was conducted at James A. Haley Veterans’ Hospital (JAHVH) in Tampa, Florida. Inclusion criteria included veterans who were diagnosed with cancer, attended an outpatient psychology-oncology evaluation, and completed mental health screening measures provided during their evaluation. Exclusion criteria included veterans who: were seen in response to an inpatient consult, were seen solely for a stem cell transplant evaluation, or did not complete the screening measures.

Measures

A veteran’s demographic (eg, age, sex, ethnicity) and clinical (eg, cancer type, stage of disease, recurrence, cancer treatments received) information was abstracted from their VA medical records. Marital status was assessed during a clinical interview and documented as part of the standardized suicide risk assessment.
