目的:考察不同自我管理水平2型糖尿病(T2DM)患者对情绪信息注意偏向的成分和时程特征。方法:采用糖尿病自我管理活动问卷(SDSCA)筛选出高、中、低自我管理水平患者各63例,应用点探测任务考查不同类型的刺激图片和呈现时间时患者注意偏向的成分和时程特征。结果:刺激呈现500ms时,高自我管理水平组在线索一致条件下,对正性图片的平均反应时小于对负性图片的平均反应时[(597.8±185.5)ms vs.(626.0±186.6)ms,P<0.01],高自我管理水平组负性注意偏向值和负性指向指数均<0[(-22.5±79.0)ms、(-26.6±74.5)ms,P<0.05或P<0.01];中自我管理水平组负性脱离指数>0[(17.2±60.3)ms,P<0.05];低自我管理水平组正性脱离指数<0[(-22.6±74.8)ms,P<0.05]。刺激呈现1250ms时,中自我管理水平组正性指向指数>0[(14.9±54.4)ms,P<0.05]。结论:自我管理水平不同的2型糖尿病患者对情绪刺激的注意偏向不同。
OBJECTIVE: To investigate the compositional and time-history features of attentional bias toward emotional information in patients with different self-management levels of type 2 diabetes mellitus (T2DM). Methods: Sixty-three patients with high, medium and low self-management level were screened by self-management activity questionnaire of diabetes mellitus (SDSCA), and the components and time-history characteristics of patients with different types of stimulus pictures and presentation time were investigated by using point exploration task. Results: When the stimulus was 500ms, the mean response time to positive pictures was less than that to negative pictures [(597.8 ± 185.5) ms vs. (626.0 ± 186.6) ms, , P <0.01]. The scores of negative attention and negative directions in the high self-management group were all less than 0 (-22.5 ± 79.0) ms, (-26.6 ± 74.5) ms, P <0.05 or P <0.01] (P <0.05). The positive index of self-management in the self-management group was lower than that in the self-management group (P <0.05). At 1250 ms of stimulation, the positive index of self-management level group was> 0 [(14.9 ± 54.4) ms, P <0.05]. CONCLUSIONS: Patients with type 2 diabetes who have different levels of self-management pay particular attention to emotional stimuli.
