The Suicide Cognitions Scale (SCS) measures suicide-related beliefs proposed by the Fluid Vulnerability Theory. A recent investigation of a revised version of the SCS (i.e., SCS-R) which omits items explicitly referencing suicide has indicated that the measure is highly influenced by a general factor and may be useful for distinguishing severity levels of suicidal thoughts and behaviors; however, limited concurrent validity studies with a range of suicide-related experiences have been conducted. As such, this study replicated and extended previous psychometric research on the SCS-R in an online survey study with a community sample of N = 10,625 U.S. adults. Results confirmed the unidimensional structure of the SCS-R. Logistic regression analyses indicated that the total score of the SCS-R is useful in distinguishing varying levels of suicidal thoughts and behaviors such as past-month planning for suicide without attempt versus past-month suicide attempt. Implications and limitations are discussed.

To examine the role of various forms of social support as a protective factor for transgender and gender diverse individuals against suicidal ideation. Data analyzed in the current study were part of the 2017 Trans Lifeline Mental Health Survey. Self-identified transgender and gender diverse (TGD) adults (N = 4147) completed an online, cross-sectional survey that included self-report measures on past-year suicidal ideation, perceived receipt of social support from others (e.g., family and chosen family), mode of social support (e.g., primarily online and primarily offline), and perceived role of social support for others. Chi-square analyses indicate that TGD individuals who reported support from both FOO and chosen family, receiving support from friends primarily offline, and providing support to friends primarily offline were less likely to report past-year SI. A logistic regression analysis further indicated that those who reported having both family and chosen family support and support from friends primarily offline were less likely to report past-year SI. TGD individuals may be protected from SI when they perceive social support from multiple relationships and sources. Public Significance StatementThis study suggests that transgender and gender diverse adults who receive social support from a number of relationships and sources are less likely to report past-year suicidal, i.e.tion (SI). Specifically, family and chosen family support, and support from friends primarily offline were associated with lower probability of reporting past-year SI.
