Abstract
According to the Schema theory（Beck, 1967）, Associative network theory（Bower, 1981） and Tripartite theory（Clark & White, 1991）, previous researchers suggested the correlation between negative attention bias and depressed mood, as well as positive attention bias and the lack of positive mood. However, empirical studies did not reveal consistent findings on attentional phenomena. Therefore, the present study aimed firstly to investigate the moderating role of the behavioral inhibition and activation system（Gray, 1982） between attentional engagement and disengagement in depressors, and secondly, to examine the relationship between individuals’ attentional phenomena and depressed mood. With an integrated design, the present study intended to further examine the mood consistent hypotheses. Two studies were included. Study one aimed to validate the Chinese version of the Behavioral Inhibition and Behavioral Activation Scale（BIS/BAS）. In the first stage（N = 150）, factor analysis was performed, and scale items were revised accordingly. In the second stage（N = 152）, factor analysis was performed on the revised scale, and its psychometric properties were examined. Study two（N = 119） aimed to examine: 1） whether the relationships between depressed mood and attentional biases were moderated by the activation level of behavioral inhibition system（BIS） and behavioral activation system（BAS）; and 2） the relationships between attentional biases and mood changes after mood induction. Results indicated that, first of all, the BIS/BAS scale showed satisfactory psychometric properties. Secondly, the correlations of depressed mood and attentional biased were insignificant overall. However, the moderating role of the BIS between depressed mood and negative attentional engagement was revealed. Specifically, when the BIS was less active, significant negative correlation was noted between depressed mood and negative attentional engagement. Finally, the correlations between participants’ attentional bias and the mood changes before and after mood induction were insignificant. Based on the above findings, the present study tried to use structure aspects such like Inhibition of Return（IOR） and Vigilance-Avoidance Theory to discuss the possible meaning of moderating effect. Possible application and future research directions were also addressed.
