Research conducted within the cognitive bias modification (CBM) paradigm has revealed that cognitive biases such as negative cognitive interpretation biases contribute to mental health disorders such as anxiety (Beard, 2011). It has been shown that exercise reduces anxiety (Ensari et al., 2015). Exercise has also been found to reduce negative cognitive attention biases (Tian and Smith, 2011), however, no research to date has investigated the effect of exercise on cognitive interpretation bias. The key aims of the current project is to investigate whether moderate exercise reduces self-reported symptoms of depression and stress. Additionally, to establish which intensity of exercise is required to achieve anxiety reduction and reduce an individual's negative cognitive interpretation biases. Study 1 recruited a healthy sample of adult participants who were randomly assigned to one of two conditions: a walking exercise protocol or a control condition ( = 2 × 12). Participants completed anxiety and cognitive interpretation bias measures before and after the walking exercise or control condition. Those in the walking exercise condition presented less symptoms of trait anxiety on a measure of state and trait anxiety inventory (STAI), compared to controls relative to baseline measures following the intervention. Study 2 recruited frequent exercisers who were assigned to an exercise or control group ( = 2 × 24). Participants completed anxiety, depression, psychological stress, and cognitive interpretation bias measures before and after the exercise or control condition. Following the intervention, negative interpretation biases decreased in the exercise group and stayed stable in the control group. The exercise group also had significantly decreased anxiety, depression, and stress measures after the exercise condition, while controls did not. The research concludes that CBM holds promise for the management of mood disorders and exercise is an effective accompaniment to psychotherapy.
在认知偏差矫正（CBM）范式下开展的研究表明，诸如消极认知解释偏差等认知偏差会导致焦虑等心理健康障碍（比尔德，2011年）。研究表明运动可减轻焦虑（恩萨里等人，2015年）。研究还发现运动能减少消极认知注意偏差（田和史密斯，2011年），然而，迄今为止尚无研究调查运动对认知解释偏差的影响。当前项目的主要目标是调查适度运动是否能减轻自我报告的抑郁和压力症状。此外，确定需要何种运动强度才能减轻焦虑并减少个体的消极认知解释偏差。研究1招募了健康的成年参与者样本，他们被随机分配到两种条件之一：步行运动方案组或对照组（ = 2×12）。参与者在步行运动或对照条件前后完成焦虑和认知解释偏差测量。与对照组相比，在干预后的状态和特质焦虑量表（STAI）测量中，步行运动组的特质焦虑症状更少。研究2招募了经常锻炼的人，他们被分配到运动组或对照组（ = 2×24）。参与者在运动或对照条件前后完成焦虑、抑郁、心理压力和认知解释偏差测量。干预后，运动组的消极解释偏差下降，而对照组保持稳定。运动组在运动后焦虑、抑郁和压力测量也显著下降，而对照组则没有。研究得出结论，CBM在情绪障碍管理方面具有前景，运动是心理治疗的有效辅助手段。
