Objective   To investigate the characteristics of attentional network impairments for the depressive symptom individuals.   Methods   A total of 21 health individuals and 22 matched depressive symptom individuals based on Beck depression inventory (BDI) and self rating depression scale (SDS) were enrolled in this study. Attentional network test was carried out on them to compare their scores of alerting

orienting and executive control network.  Results  The reaction time data showed that the main effect of cue type [F(3

117)=283.5

P0.05] and flanker type [F(2

78)=552.6

P0.05] were significant between the health individuals and depressive symptom individuals. Significant interactions were found between cue type and flanker type [F(6

234)=15.6

P0.05]

and between groups and flanker type [F(2

78)=7.26

P0.05]. Attentional network indexes showed that there was no significant difference in main effect on alerting and orienting effects between 2 groups. But on executive control

the main effect of cue type and groups were significant

suggesting that depressive symptom group had weaker executive control than health group.  Conclusion  The alerting and orienting network for the depressive symptom individuals are intact

but the executive control network is impaired.
