Abstract

Suicidal ideation (SI), a risk factor for suicide, is prevalent in internalizing psychopathologies, including depression and anxiety. Rumination and worry are well-studied repetitive negative thinking (RNT) constructs implicated in internalizing psychopathologies. These constructs have shared and distinct characteristics. However, the relationship between rumination and worry and their associations with SI are not fully understood in clinical samples. The present study used correlational and regression analysis to evaluate these relationships as a secondary data analysis in treatment-seeking participants with internalizing psychopathologies in two independent samples (Study 1:n = 143; Study 2:n = 133). Results showed about half of the participants endorsed SI (Study 1:n = 79; Study 2:n = 71). Correlations revealed a significant, positive relationship between rumination and worry. Regression results with SI as the dependent variable showed rumination significantly positively corresponded with SI in both studies. Post-hoc partial correlations controlling for symptom severity (depression, anxiety), worry, and age showed the rumination-SI relationship was maintained in both studies. Findings for worry and SI were inconsistent between studies. Findings indicate rumination, but not worry, could be a stable, unique contributor to SI in internalizing psychopathologies. It may be useful to incorporate RNT into suicide risk assessment for individuals with internalizing conditions.

内化性精神疾病中的重复性消极思维和自杀意念：重复研究

自杀意念（SI）是自杀的一个风险因素，在抑郁和焦虑等内化性精神疾病中非常普遍。反刍和担忧是经过深入研究的重复性消极思维（RNT）结构，与内化性精神疾病有关。这些建构既有共同的特点，也有各自不同的特点。然而，在临床样本中，反刍和担忧之间的关系及其与内化性精神障碍的关联还没有得到充分了解。本研究在两个独立样本（研究 1：n = 143；研究 2：n = 133）中，采用相关分析和回归分析，对寻求治疗的内化性心理变态参与者的这些关系进行了二次数据分析。结果显示，约有一半的参与者认可 SI（研究 1：n = 79；研究 2：n = 71）。相关性表明，反刍和担忧之间存在着显著的正相关关系。以 SI 为因变量的回归结果显示，在两项研究中，反刍都与 SI 呈显著正相关。控制症状严重程度（抑郁、焦虑）、担忧和年龄的事后局部相关性表明，在这两项研究中，反刍与 SI 的关系都得以维持。不同研究对担忧和 SI 的研究结果不一致。研究结果表明，反刍（而非担忧）可能是导致内化性精神障碍的一个稳定而独特的因素。将 RNT 纳入内化症患者的自杀风险评估可能会有所帮助。

期刊介绍： The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
