不同自我管理水平2型糖尿病患者的注意偏向成分和时程特征

摘要

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 explore the components and time characteristics of attentional bias in type 2 diabetic patients with different levels of self-management.Methods:The patients were first divided into higher,medium and lower self-management levels based on the Summary of Diabetes Self-care Activities Questionnaire (SDSCA),63 subjects in each group.A probe detection task was used to examine the impact of the different emotional pictures and stimulus presenting time on attentional bias.Results:When the stimuli were displayed for 500 ms,patients with higher self-management levels showed shorter reaction time to positive pictures than to negative pictures [(597.8 ± 185.5) ms vs.(626.0 ± 186.6) ms,P ＜ 0.01],and their scores of negative attentional bias [(-22.5 ± 79.0) ms,P ＜0.05] and negative orienting index were lower than 0[(-26.6 ±74.5) ms,P ＜0.01].The scores of negative disengaging index were significant higher than 0 in patients with medium self-management levels [(17.2 ± 60.3) ms,P ＜0.05],the scores of positive disengaging index were significant lower than 0 in patients with lower selfmanagement levels [(-22.6 ±74.8) ms,P ＜0.05]].When the stimuli were displayed for 1250 ms,the scores of positive orienting index were higher than 0 in patients with medium self-management levels [(14.9 ± 54.4) ms,P ＜ 0.05].Conclusion:It suggests that there are different characteristics of implicit cognitive processing in patients with different levels of self-management.
