DESCRIPTION (provided by investigator): Major depressive disorder, disruptive behavior disorders, and anxiety disorders are all significantly associated with suicidal ideation and attempts in adolescents. Yet, the nature of the relation between psychopathology and suicidality has been greatly understudied. The purpose of this 3-year application is to test a cognitive mediational model to explain this relationship. Specifically, it is hypothesized that psychopathology is related to suicidality through unique dysfunctional cognitive processes and products linked with various clinical disorders in adolescents. The proposed study will also explore the manner in which comorbid forms of psychopathology affect dysfunctional cognitive processes and products, and suicidality in adolescents. It is hypothesized that depressed adolescents with comorbid psychopathology will exhibit more severe dysfunctional cognitive processes and products, and thus further increase their suicide risk. Secondarily, gender differences across mediational and comorbidity related findings would be explored. More complex competing models will also be tested. The proposed study will employ a cross-sectional design to test hypotheses. Two hundred and fifty psychiatrically hospitalized adolescents will be asked to complete a diagnostic interview and symptom inventories to assess psychopathology, as well as performance based measures and questionnaires to assess dysfunctional cognitive processes, cognitive products, and suicidality. Analyses will include the use of structural equation modeling (SEM) techniques, hierarchical regression analyses, and analyses of variance (ANOVA). Information obtained from this study will help explicate cognitive patterns in suicidal adolescents with varying forms of psychopathology and could ultimately be used to tailor cognitive-behavioral and multimode interventions for these high risk youth.

描述（由研究者提供）：重度抑郁症，破坏性行为障碍和焦虑症都与自杀的观念和青少年尝试显着相关。然而，精神病理学与自杀性之间关系的性质已经大大研究了。该三年应用的目的是测试一个认知中介模型来解释这种关系。具体而言，假设心理病理学通过独特的功能障碍的认知过程和与青少年各种临床疾病相关的独特的认知过程和产品与自杀性有关。拟议的研究还将探索合并症形式的心理病理学形式影响功能失调的认知过程和产品，以及青少年的自杀性。假设患有合并症心理病理学的抑郁症青少年将表现出更严重的认知过程和产品，从而进一步增加了自杀风险。其次，将探讨中介和合并症相关发现之间的性别差异。还将测试更复杂的竞争模型。拟议的研究将采用横截面设计来检验假设。将要求250名精神病院住院的青少年完成诊断性访谈和症状清单，以评估心理病理学以及基于绩效的措施和问卷，以评估功能障碍的认知过程，认知产物和自杀性。分析将包括使用结构方程建模（SEM）技术，分层回归分析和方差分析（ANOVA）。从这项研究中获得的信息将有助于阐明具有不同形式的心理病理学的自杀青少年的认知模式，并最终可用于针对这些高风险青年来量身定制认知行为和多模干预。
