这项研究纵向检查了符合亚综合征季节性情感障碍（S-SAD）标准和非抑郁、低季节性对照的女性的认知和心理生理因素。参与者（N = 46）在一个冬季月份（即，12月或1月）和一个非冬季月份（即，9月或4月）。在每次评估中，参与者完成了负面自动思维频率，情绪和季节性以及三个实验任务（心理生理任务，示意图任务和修改后的Stroop任务）的措施。S-SAD和对照组的女性在自动消极想法的频率和对光相关刺激的情绪和心理生理反应的评估上都不同。这些结果强调了研究的必要性，研究可能的认知脆弱性，症状的发展和维持整个频谱的季节性。
This study longitudinally examined cognitive and psychophysiological factors in females who met criteria for subsyndromal seasonal affective disorder (S-SAD) and nondepressed, low seasonality controls. Participants (N = 46) were tested twice, during one winter month (i.e., December or January) and during one nonwinter month (i.e., September or April). At each assessment, participants completed measures of negative automatic thought frequency, mood, and seasonality as well as three experimental tasks ( a psychophysiological task, a schematic faces task, and a modified Stroop task). Women with S-SAD and controls differed at both assessments on frequency of automatic negative thoughts and emotional and psychophysiological reactivity to light-relevant stimuli. These results highlight the need for research examining a possible cognitive vulnerability to symptom development and maintenance across the spectrum of seasonality.
