چکیده انگلیسی


- The simultaneous contributions of RDoC constructs to suicidality are assessed.
- In this high-risk sample, all symptom domains exhibited a full range of severity.
- Reward and negative valence system disturbances correlated with suicidality.
- Only anhedonia and entrapment were independently associated with suicidality.

BackgroundSuicide remains poorly understood and unpredictable. Addressing this challenge, this study examined the independent contributions of several research domain criteria (RDoC) constructs in relation to suicidality in patients hospitalized for acute suicide risk. Specifically, we examined anhedonia, anxiety/entrapment, and attachment disturbances, reflecting disturbances in reward processes, negative valence systems, and social processes, respectively.MethodsAnhedonia, anxiety, entrapment, and fearful attachment, were assessed quantitatively in 135 adults hospitalized for suicidality. Current suicidality and suicidal history were assessed with the Columbia Suicide Severity Rating Scale. Bivariate analyses (with significance threshold of p<.01 to account for multiple comparisons) and multivariate models examined relationships between symptom dimensions and severity of suicidal ideation (SI). We also assessed differences between patients with a history of suicide attempt and those who exhibited only suicidal ideations.ResultsUsing bivariate analyses all symptoms except for fearful attachment correlated robustly with SI (r =.37-0.50, p<.001). However, when using multivariate analyses, only anhedonia (β=.28, p=.01) and entrapment (β=.19, p=.03) were independently associated with SI across the entire sample. No functional domain measures differed between patients with history of suicide attempt versus ideation only.LimitationsThe reliance on self-report data and a cross-sectional design.ConclusionsDisturbances in reward and threat processing may represent independent factors in the development of suicidal ideation in this high suicide risk cohort. Future studies should assess their role as risk factors.
