A Preliminary Validation of the Suicidal Behavior Exposure Scale.

ABSTRACT: Objective:Research on suicide contagion has suggested that exposure to suicide-related thoughts and behaviors of others promotes one's personal risk for suicide. However, our understanding of the role suicidal exposure plays in the development of suicide risk is underdeveloped. This limited understanding may be due, in part, to the lack of a validated measure of exposure to suicidal behavior. The present study aimed to develop and validate a comprehensive self-report instrument of exposure to suicidal behaviors. Method:Using two independent convenience samples of undergraduate students, exploratory structural equation modeling (ESEM) was performed on a newly developed measure of suicidal exposure. Results:Data supported a three-factor model of suicidal exposure: exposure to suicidal communication, direct exposure to suicide deaths and attempts, and indirect exposure to suicide deaths and attempts. Each factor demonstrated positive bivariate associations with depressive symptoms, posttraumatic stress disorder symptoms, suicide ideation, and suicide attempt history, suggesting convergent validity. Analyses demonstrated generally acceptable internal consistency. Conclusion:This instrument will facilitate the study of suicidal exposure. Further validation of this scale, with attention to its reliability and invariance across gender and other demographic variables in clinically relevant samples, will be important for advancing the assessment of suicidal exposure and understanding its relation to suicide risk.

Project description:BackgroundSelf-regulation refers to a person's ability to manage their cognitive, emotional, and behavioral processes to achieve long-term goals. Most prior research has examined self-regulation at the individual level; however, individual-level assessments do not allow the examination of dynamic patterns of intraindividual variability in self-regulation and thus cannot aid in understanding potential malleable processes of self-regulation that may occur in response to the daily environment.ObjectiveThis study aims to develop a brief, psychometrically sound momentary self-regulation scale that can be practically administered through participants' mobile devices at a momentary level.MethodsThis study was conducted in 2 phases. In the first phase, in a sample of 522 adults collected as part of a larger self-regulation project, we examined 23 previously validated assessments of self-regulation containing 594 items in total to evaluate the underlying structure of self-regulation via exploratory and confirmatory factor analyses. We then selected 20 trait-level items to be carried forward to the second phase. In the second phase, we converted each item into a momentary question and piloted the momentary items in a sample of 53 adults over 14 days. Using the results from the momentary pilot study, we explored the psychometric properties of the items and assessed their underlying structure. We then proposed a set of subscale and total score calculations.ResultsIn the first phase, the selected individual-level items appeared to measure 4 factors of self-regulation. The factors identified were perseverance, sensation seeking, emotion regulation, and mindfulness. In the second phase of the ecological momentary assessment pilot, the selected items demonstrated strong construct validity as well as predictive validity for health risk behaviors.ConclusionsOur findings provide preliminary evidence for a 12-item momentary self-regulation scale comprising 4 subscales designed to capture self-regulatory dynamics at the momentary level.

Project description:OBJECTIVE:Clinical heterogeneity is a key challenge to understanding suicidal risk, as different pathways to suicidal behavior are likely to exist. We aimed to identify such pathways by uncovering latent classes of late-life depression cases and relating them to prior and future suicidal behavior. METHODS:Data were collected from June 2010 to September 2015. In this longitudinal study we examined distinct associations of clinical and cognitive/decision-making factors with suicidal behavior in 194 older (50+ years) nondemented, depressed patients; 57 nonpsychiatric healthy controls provided benchmark data. The DSM-IV was used to establish diagnostic criteria. We identified multivariate patterns of risk factors, defining clusters based on personality traits, perceived social support, cognitive performance, and decision-making in an analysis blinded to participants' history of suicidal behavior. We validated these clusters using past and prospective suicidal ideation and behavior. RESULTS:Of 5 clusters identified, 3 were associated with high risk for suicidal behavior: (1) cognitive deficits, dysfunctional personality, low social support, high willingness to delay future rewards, and overrepresentation of high-lethality attempters; (2) high-personality pathology (ie, low self-esteem), minimal or no cognitive deficits, and overrepresentation of low-lethality attempters and ideators; (3) cognitive deficits, inability to delay future rewards, and similar distribution of high- and low-lethality attempters. There were significant between-cluster differences in number (P < .001) and lethality (P = .002) of past suicide attempts and in the likelihood of future suicide attempts (P = .010, 30 attempts by 22 patients, 2 fatal) and emergency psychiatric hospitalizations to prevent suicide (P = .005, 31 participants). CONCLUSIONS:Three pathways to suicidal behavior in older patients were found, marked by (1) very high levels of cognitive and dispositional risk factors suggesting a dementia prodrome, (2) dysfunctional personality traits, and (3) impulsive decision-making and cognitive deficits.
