Abstract:
Objective:To explore the differences of attention bias performance between patients with heroin dependence in methadone maintenance treatment(MMT) and healthy controls.Methods:A total of 38 heroin dependent patients in the Fourth People's Hospital of Huainan from January 2018 to September 2018 were selected as MMTgroup, and 32 gender-and age-matched healthy controls were selected as healthy control(HC) group.The attention bias was evaluated by Emotional Stroop Task, and the difference between the two groups was compared.Results:The error number of the herion-related words in Emotional Stroop Task of MMT group was lower than that of HC group[0.75(2, 5) vs.1(0, 2)], the difference was statistically significant( Z=-2.184, P=0.029). The number of errors in point and neutral words and reaction time of point, neutral word and clue word had no statistically significant differences between MMT group and HC group[1(0, 4) vs.1(0, 2); 3(2, 5) vs.2(2, 3); (1 055.14±303.50)ms vs.(985.40±173.71)ms, (1 126.89±347.82)ms vs.(1 022.76± 173.62)ms; (1 188.53±371.80)ms vs.(1 113.23±225.11)ms]( Z=-1.331, P=0.183; Z=-1.723, P=0.085; t=1.150, P=0.254; t=1.539, P=0.129; t=1.001, P=0.320). There were no statistically significant differences in attention bias influenced by the dosage and duration of methadone between MMT group and HC group(all P>0.05). Conclusion:These results demonstrate that heroin dependence patients in MMT have attentional bias in heroin-related words.Methadone has no effect on attention bias in patients with heroin dependence during maintenance treatment intervention.
