4 Suicide Risk Assessment Tools and Instruments
The Beck Hopelessness Scale (BHS; Beck et al. 1988) was designed to measure negative attitudes about one’s future and perceived inability to avert negative life events. It has 20 true/false statements to measure three aspects of hopelessness: • Negative feelings about the future • Loss of motivation • Pessimistic expectations Each of the 20 statements is scored 0 or 1. The published cutoff score for the BHS is greater than 9 (Beck et al. 1985). The BHS is not supported for use in identifying individuals at high risk of repetitive, non-suicidal self-injury nor is it supported for use in emergency settings (Cochrane-Brink et al. 2000). The Beck Scale for Suicide Ideation (BSS ®; Beck et al. 1979) measures the current and immediate intensity of attitudes, behaviors, and plans for suicide-related behavior with the intent to end life among psychiatric patients. The scale consists of 21 items that are rated on a 3-point scale of suicidal intensity (e.g., 0–2). In a 20-year prospective study, patients considered at high risk were seven times more likely to die by suicide than those patients considered at lower risk (Brown et al. 2000). Predictive validity of the BSS® for acute suicide was not found in the literature. It is one of the most widely used measures of suicide-related ideation and has been extensively studied. It has been shown to differentiate between adults and adolescents with and without a history of suicide attempts (Holi et al. 2005). A two-factor model of motivation (e.g., wishes, reasons, desires) and preparation (e.g., planning and acting) was established among a sample of female suicide attempters. The Geriatric Suicide Ideation Scale (GSIS; Heisel and Flett 2006) is a multidimensional measure of suicide-related ideation developed for use with older adults. It is composed of 31 questions with scores ranging from 31 to 165. The GSIS has four factors: • Suicide ideation (e.g., “I want to end my life”) • Perceived meaning in life (e.g., “Life is extremely valuable to me,” reverse keyed) • Loss of personal and social worth (e.g., “I generally feel pretty worthless”) • Death ideation (e.g., “I often wish I would pass away in my sleep”) and one additional item (e.g., “I have tried ending my life in the past”) The interRAI Severity of Self-harm (SOS Scale) measures risk of harm to self (suicide and self-harm) based on historical and current suicide ideation, plans, and behaviors as well as indicators of depression, hopelessness, positive symptoms, cognitive functioning, and family concern over the person’s safety. The SOS Scale uses hierarchical scoring algorithm producing scores ranging from 0 (no risk) to 6 (extreme or imminent risk).
