Negative mood is associated with increased worry levels, and also with deployment of a systematic information processing style. An experimental study assessed the potential role of systematic information processing in mediating the facilitative effect of negative mood on worry (e.g. Johnston & Davey, 1997).
Participants underwent appropriate vignette-based mood inductions (negative, neutral, and cognitive priming). Participants completed visual analogue scales measuring variables that reflect a raised processing sufficiency threshold and are known to increase systematic processing (responsibility, accountability, desire for control, and need for cognition), a measure of 'as many as can' worry stop rule deployment, and two measures of worry (the catastrophising interview and the Penn State Worry Questionnaire, PSWQ, Meyer, Miller, Metzger, & Borkovec, 1990).
Experimentally-induced negative mood facilitated the endorsement of cognitive appraisals known to increase systematic as opposed to heuristic information processing. In addition, a meditational analysis showed that the systematic processing facilitators measure together with a measure of 'as many as can' worry stop rule deployment fully mediated the relationship between negative mood and a measure of worry frequency (PSWQ).
Future studies should develop and validate direct measures of systematic processing.
Similarities and differences between systematic processing and chronic worrying as effortful forms of information processing are discussed, and a role for systematic processing as an information processing style relevant to understanding worrisome thought is described.
负面情绪与担忧水平的增加有关，也与系统信息处理风格的运用有关。一项实验研究评估了系统信息处理在中介负性情绪对担忧的促进作用（例如，Johnston 和 Davey，1997）中的潜在作用。
参与者接受了适当的基于情景的情绪诱导（负性、中性和认知启动）。参与者完成了衡量反映处理充足性阈值提高并已知增加系统处理的变量的视觉模拟量表（责任、问责制、控制欲望和认知需求）、衡量“尽可能多”的担忧停止规则部署的量表，以及衡量担忧的两个量表（灾难化访谈和宾夕法尼亚州担忧问卷，PSWQ，Meyer、Miller、Metzger 和 Borkovec，1990）。
实验诱导的负性情绪促进了已知增加系统而非启发式信息处理的认知评估的认可。此外，中介分析表明，系统处理促进因素的衡量与“尽可能多”的担忧停止规则部署的衡量一起，完全中介了负性情绪与担忧频率的衡量（PSWQ）之间的关系。
未来的研究应该开发和验证系统处理的直接衡量。
讨论了系统处理和慢性担忧作为费力的信息处理方式之间的相似性和差异，并描述了系统处理作为与理解担忧性思维相关的信息处理方式的作用。
