Abstract:
Objective:To examine whether dysfunctional attitudes and cognitive bias change with fluctuations in depressive symptoms. Methods:122 patients with MDD (major depressive disorder) were assessed with DAS (dysfunctional attitude scale),CBQ (cognitive bias questionnaire) ,and HRSD (Hamilton rating scale for depression) before and after the 8-week treatment. 51 normal subjects were assessed with the DAS, CBQ and SDS as controls.Results:(1) Compared with normal controls, at the baseline MDD patients had significantly higher total DAS scores (158.2?34.6 vs. 119.3?23.4,t=8.559, P=0.000) and the score of CBQ (5.19?3.77 vs. 1.69?1.83, t=8.208, P=0.000). (2) After 8 weeks, the HRSD scores of patients reduced to Median 7.0, and the DAS and CBQ scores significantly lower than those in baseline (DAS total score from 158.2?34.6 to 143.3?29.3, t=3.611, P=0.000; the median of CBQ decreased from 5.0 to 3.0;z=4.670, P=0.000). (3) The DAS score (131.1?25.7) and CBQ score (median 3.0) of full recovery patients with full recovery remained higher than those of controls (t=2.397, P=0.018 ;z=3.990, P=0.000).Conclusion:Dysfunctional attitudes and cognitive bias were influenced by fluctuations in stata or demonstrateing stability over time. They were all state-trait features.
