Burden, Belonging, and Response to Pain in Veterans

Overview

The primary purpose of the current study is to rigorously test the psychometric properties of the INQ-12 and ACSS (Van Orden et al., 2008) in Veterans, something which has not been done to date. Factor structure, internal consistency, convergent and discriminant validity will all be assessed. Secondary goals are to determine if burdensomeness, failed belongingness, and acquired capability are distinct versus overlapping constructs and whether or not values mediate the relationship between reasons for living and suicide risk. Lastly, the inclusion of the Beck Scale for Suicidal Ideation (BSS) allows us to analyze participants' responses to explore whether or not participants can be grouped into those who want to die by suicide because they want to escape their problems and those who want to die to influence other people.

Suicide is a significant problem among Veterans of the U.S. Military. Katz (2007) reported that there were 144 suicides among Veterans who served in Operation Enduring Freedom (OEF) and/or Operation Iraqi Freedom (OIF) from 2002-2005. There is no nationwide surveillance system that tracks Veteran suicides. However, the National Violent Death Reporting System (NVDRS) created in 2003 by the Centers for Disease Control and Prevention (CDC) with the purpose of gathering thorough information about suicides and other violent deaths allows researchers to reasonably extrapolate national suicide rates for Veterans. A CDC report (2006) based on NVDRS data estimated that approximately 6,500 veterans from all wars die by suicide each year, accounting for approximately 20% of suicides per year nationwide. While much is known about risk factors for suicide (e.g., Beck, Steer, Kovacs, \& Garrison, 1985; Jobes \& Mann, 1999) such information has little clinical utility for predicting whether or not an individual is likely to die by suicide in the near-term. One of the few attempts to address this issue is the interpersonal-psychological theory of suicide (Joiner, 2005). The interpersonal psychological theory proposes that people die by suicide for three reasons: (1) they perceive themselves as a burden to others; (2) they experience a profound feeling of disconnectedness from others, what Joiner (2005) calls ''thwarted belongingness'' (p. 118); and (3) they have become habituated to the fear and physical pain inherent in a suicidal act by repeatedly enduring painful and provocative situations, whether through such experiences as repeated suicide attempts, other physically painful experiences, or frequent exposure to danger. Importantly, all three factors must be present for a suicide to occur, according to the interpersonal-psychological theory; together, these three characteristics are ''proximal, causal, interactive risk factors'' (Van Orden, Witte, Gordon et al., 2008a, p. 72). Components of the theory have been tested in adults (Joiner, Pettit, Walker, Voelz, Cruz, \& Rudd, 2002; Joiner \& Rudd, 2000), college students, and adolescents (Joiner, Rudd, Rouleau, \& Wagner, 2000). However, research has only begun to explore whether the theory applies to Veterans (Cornette, Deboard, Clark, Holloway, Brenner, Gutierrez, et al., 2007; Cornette, deRoon-Cassini, Joiner, \& Proescher, 2006). Brenner et al. (2008) conducted a qualitative study of OEF/OIF Veterans which found relevance of the theory to their experiences. In particular, themes emerged around combat as a context for exposure to painful stimuli, perceptions of burdensomeness, and failed belongingness. This theory shows promise for designing prevention and clinical intervention strategies for Veterans, but more data are needed on which to base such work. To facilitate testing the interpersonal-psychological theory of suicide, Joiner and colleagues have developed several instruments (Bender, Gordon, \& Joiner, 2007; Bryan, Morrow, Anestis, \& Joiner, 2010; Van Orden,Witte, Gordon et al., 2008a). The Interpersonal Needs Questionnaire (INQ) taps into the constructs of thwarted belongingness and perceived burdensomeness. The Acquired Capability for Suicide Scale (ACSS; Van Orden et al., 2008) measures fearlessness about suicide. The current study will focus on the 12-item version of the INQ (INQ-12; Van Orden, Witte, Gordon, Bender, \& Joiner, 2008a) recently validated by Freedenthal, Lamis, Osman, Kahlo, and Gutierrez (2011). This measure contains seven items that assess perceived burdensomeness and five items that assess belongingness. An example of a burdensomeness item in the INQ-12 is, ''These days, I think I have failed the people in my life''. An example of a belongingness item is, ''These days, other people care about me''. The ACSS is a 20-item measure rated on a scale of 1 (not at all like me) to 5 (very much like me). Sample items include, "I am not at all afraid to die" and "I can tolerate a lot more pain than most people". Van Orden et al. report acceptable convergent and discriminant validity. The authors also reported a strong negative correlation with the fear of suicide subscale on the Reasons for Living Inventory (RFL; Linehan, Nielsen, \& Chiles, 1983) and a positive correlation with the courage to kill oneself item on the Beck Scale for Suicide Ideation (BSS; Beck \& Steer, 1991). Bender, Gordon, Bresin, and Joiner (2011) reported acceptable internal consistency as well. However, formal psychometric studies of the ACSS have yet to be conducted. Joiner (2005) describes burdensomeness, failed belongingness and acquired capability as separate constructs, with the INQ-12 and ACSS designed to assess each independently. However, for purposes of explaining whether a given individual is likely to die by suicide, Joiner et al. (2009) explain that the first two constructs together create the desire for death and that the third is necessary for a person to engage in potentially lethal self-harm behavior. Therefore, a complex interaction between the three is proposed. Support for this interaction was found by Joiner et al. in two independent samples, one community sample of young adults and a second drawing on archival data from active duty military personnel being treated for a recent significant suicide-related event (e.g., serious ideation or attempt). A major limitation of this study was that measures of the constructs differed, making it somewhat difficult to determine what was being assessed in the two samples. Additionally, in their psychometric examination of the INQ-12 Freedenthal and colleagues (2011) found evidence of an overarching factor uniting the two subscales of burdensomeness and failed belongingness. Assessing for suicide risk is a key element of the clinical management of high-risk individuals (Gutierrez et al., 2009), but is only the first step. To adequately select appropriate interventions clinicians must know what is driving an individual's suicidality (Jobes, 2006) and also what factors are keeping the person from acting on their thoughts and urges. This information better helps the clinician and client to develop strategies aimed at creating (or rediscovering) what makes life worth living; focusing on plans, goals, and hope for the future (Jobes, Comtois, Brenner, \& Gutierrez, 2011). Historically, the RFL (Linehan et al., 1983) has been one of the primary measures of protective factors against suicide, and indeed has shown great utility. A potentially related area of study is the role of one's values. The consciously chosen way in which an individual lives her life, the driving force behind her actions, and the desired outcomes of her behaviors define what an individual values (Luoma, Hayes, \& Walser, 2007). Helping clients live lives consistent with their values provides purpose and meaning, gives direction to their choices, and allows them to set reasonable, flexible goals likely to motivate meaningful action (Luoma et al.). Accomplishing these things should greatly facilitate reducing an individual's risk of suicide, since it answers the fundamental existential question "why is life worth living?" Ciarrochi and Bailey (2008) created the Survey of Life Principles to assess values, and provide preliminary support for its use in their manual.
