Abstract:
In response to shortcomings with the current diagnostic classification system for mental health disorders, such as poor validity and reliability of categorical diagnoses, the National Institute of Mental Health proposed the Research Domain Criteria (RDoC) initiative to move towards a dimensional approach using translational research. The current study examined associations between measures of behaviors, cognitions, and mental health symptoms and how they overlap in the Negative Valence Systems (NVS) domain. Specifically, we examined how the Self-Reports unit of analysis reflects the RDoC NVS constructs of acute threat, potential threat, sustained threat, frustrative nonreward, and loss. The overall goal was to identify additional self-report measures that reflect these constructs. Participants, two student samples and two community samples (total N = 1,509), completed online self-reported measures. Questionnaire total and subscale scores were submitted to a principal-axis factor analysis with Promax rotation separately for each sample. For both student samples and one community sample six-factor solutions emerged reflecting major aspects of the RDoC NVS and positive valence systems, particularly acute threat (i.e., fear/panic), potential threat (i.e., inhibition/worry), sustained threat (i.e., chronic stress), loss (i.e., low well-being), frustrative nonreward (i.e., reactive aggression), and reduced behavioral activation. The second community sample differed in that fear/panic and frustration/anger was combined in a general distress factor. Recommendations for additional NVS self-report markers are discussed.
摘要:
针对目前精神卫生障碍诊断分类体系存在的不足,如分类诊断的有效性和可靠性差,美国国家心理健康研究所提出了研究领域标准(RDoC)倡议,以采用转化研究的维度方法。当前的研究检查了行为测量之间的关联,认知,和心理健康症状,以及它们如何在负价系统(NVS)领域重叠。具体来说,我们研究了自我报告分析单元如何反映急性威胁的RDoCNVS构造,潜在威胁,持续的威胁,令人沮丧的不奖励,和损失。总体目标是确定反映这些结构的其他自我报告措施。参与者,两个学生样本和两个社区样本(总计N=1,509),完成在线自我报告的措施。问卷总分和子量表得分分别提交给每个样本的Promax旋转的主轴因子分析。对于学生样本和一个社区样本,出现了反映RDoCNVS和正价系统主要方面的六因素解决方案,特别严重的威胁(即,恐惧/恐慌),潜在威胁(即,抑制/担心),持续威胁(即,慢性压力),损失(即,低幸福感),挫折的非奖励(即,反应性侵略),减少行为激活。第二个社区样本的不同之处在于,恐惧/恐慌和沮丧/愤怒结合在一般的痛苦因素中。讨论了有关其他NVS自我报告标记的建议。
