Objective:To compare the motivated forgetting ability between adolescents with depression and normal adolescents and to explore the relationship of this ability with childhood trauma and symptoms of depression.Methods:Totally 141 adolescents diagnosed with depression according to the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5),and 42 normal controls participated in the study.The directed forgetting(DF)task was employed,using emotional images as memory stimuli,to compare the recognition per-formance between the two groups.The presence of the DF effect was identified when the recognition score under the"to-be-remembered"condition was significantly higher than the"to-be-forgotten"condition.The Childhood Trauma Questionnaire Short Form(CTQ-SF)and Beck Depression Inventory-Ⅱ(BDI-Ⅱ)were utilized to assess the severi-ty of participants'childhood trauma and depression symptoms.Results:Unlike the control group,the adolescents with depression only exhibited the DF effect with positive stimuli(P＜0.001).In the depression group,the DF effect value for negative stimuli partially mediated the relationship between CTQ-SF scores and BDI-Ⅱ scores(effect size=0.10,95％confidence interval 0.05-0.17,accounting for 21.3％of the total effect).Conclusion:The motivated forgetting ability is partially impaired in adolescents with depression.The ability,especially regarding negative memories,plays a partial mediating role between childhood trauma and depressive symptoms in adolescents with depression.

Objective:To explore the relationship between relapse tendency and childhood maltreatment in methamphetamine-dependent youths,and the role of impulsivity and quality of life in the relationship.Methods:To-tally 287 methamphetamine-dependent youths(160 females,127 males)were selected in compulsory drug rehabili-tation centers.The Relapse Tendency Questionnaire(RTQ),Childhood Trauma Questionnaire-Short Form(CTQ-SF),Barrett Impulsivity Scale(BIS-11)and Quality of Life for Drug Addicts(QOL-DA)for Drug Addicts were used to conduct the survey.SPSS macro program PROCESS was used to test the mediating role.Results:The BIS-11 total scores acted as a partial mediator between the total scores of CTQ-SF and RTQ,with an effect value of 0.03(95％CI:0.01-0.05),the QOL-DA total scores acted as a full mediator between the total scores of CTQ-SF and RTQ,with an effect value of 0.05(95％CI:0.02-0.08),and the scores of BIS-11 and QOL-DA acted as chain mediators between total scores of CTQ-SF and RTQ,with an effect value of 0.01(95％CI:0.00-0.03).Conclusion:Childhood maltreatment,impulsivity,and quality of life may be associated with relapse tendencies in methamphetamine-dependent youths.

Objective:To explore the relationship between relapse tendency and psychological craving in fe-male methamphetamine(MA)-dependent young adults,focusing on the roles of self-control and future time per-spective.Methods:A total of 340 MA-dependent young adults from two women's compulsory isolation drug reha-bilitation centers in Sichuan Province were included.Participants were assessed with the Relapse Tendency Ques-tionnaire(RTQ),Obsessive Compulsive Drug Use Scale(OCDUS),Drug Abuser Self-Control Ability Question-naire(DASAQ)and General Future Time Perspective Scale(GFTPQ).The moderated mediation model was ana-lyzed by using the SPSS macro program PROCESS(version4.2).Results:The RTQ scores were positively correla-ted with the OCDUS scores(r=0.45,P＜0.001).The DASAQ scores partially mediated the relationship between the scores of OCDUS and RTQ,accounted for 37.91％of the total effect.The GFTP scores moderated the relation-ship between the scores of the OCDUS,DASAQ and RTQ(β=-0.18,0.19,P＜0.001).Conclusion:The influ-ence of psychological craving on relapse tendency in female MA-dependent young adults exhibits a moderated me-diating effect,suggesting the potential of enhancing self-control and future time perspective for preventing relapse and improving detoxification efficiency.

Objective:To explore the influence of social exclusion on the relapse tendency of female drug re-hab patients,and the mediating role of self-esteem and the moderating role of positive psychological capital.Method:A total of 288 female drug rehabilitation patients were selected,and the Social Exclusion Question-naire(SEQ)was used to assess the degree of social exclusion experienced by the patients.The Relapse Tendency Questionnaire(RPQ)was used to evaluate the current tendency of drug relapse.The Rosenberg Self-Esteem Scale(RSES)was used to evaluate the self-esteem level of the patients,and the Positive Psychological Capital Question-naire(PPCQ)was used to evaluate their level of positive psychological capital.Results:The SEQ scores of female drug rehab patients were positively correlated with the RPQ scores(β=0.41,P＜0.001),The RSES scores had a mediating effect between the scores of SEQ and RPQ,with a mediation effect size of 0.09(95％CI:0.04-0.15,accounting for 20.6％of the total effect).The PPCQ scores had a moderating effect between the scores of RSES and RPQ(β=-0.08,P＜0.05)and between the scores of SEQ and RPQ(β=0.10,P＜0.05).Conclusion:So-cial exclusion could not only directly affect but also indirectly affect the relapse tendency through self-esteem of fe-male drug rehab patients.Positive psychological capital could moderate the relationship between social exclusion,self-esteem,and relapse tendency.

Objective:To explore the characteristics of executive function and alterations in monoamine neurotransmitters in methamphetamine-dependent adolescents and to analyse the relationship between executive function and monoamine neurotransmitters.Methods:From January to March 2017, totally 50 female methamphetamine-dependent adolescents and 50 male methamphetamine-dependent adolescents were selected as the experimental group in two compulsory isolation drug rehabilitation centres in Sichuan Province, while normal adolescents (50 males and 50 females) matching the age and gender of the experimental group were recruited as the control group in a school.Executive function was tested by the N-back test, colour word interference test and Hanoita test, and serum levels of dopamine, 5-hydroxytryptamine, epinephrine and norepinephrine were measured using high-performance liquid chromatography with fluorescence detection.Statistical analysis was performed by SPSS 21.0 software.The t-test was used to compare the differences of executive function between the experimental group and control group, and Pearson correlation analysis was used to assess the correlation between executive functions and monoamine neurotransmitters in the experimental group. Results:The differences in the number of correct 0-back responses ((105.38±17.00) vs (114.05±5.29) ) and correct response time ((728.82±110.95) ms vs (652.24±89.88) ms), number of correct 2-back responses ((54.78±23.04) vs ( 74.01±12.01)) and correct response time ((585.74±245.35) ms vs (477.44±181.26) ms), the number of correct responses in the Stroop task ((29.68±7.19) vs (33.60±7.36)) and correct response time ((973.73±228.27) ms vs ( 916.11±98.54) ms), and the number of TOH movement steps ((99.42±32.83) vs (87.70±32.55)) were statistically significant in the experimental group compared to the control group(all P<0.05). In the experimental group, serum dopamine ((5.06±1.55) μg/mL vs (3.18±1.97) μg/mL), 5-hydroxytryptamine ((351.94±119.90) ng/mL vs (149.27±69.24) ng/mL), epinephrine ((555.66±225.55) ng/mL vs (129.20± 81.39) ng/mL), and norepinephrine ((3.63±0.96) ng/mL vs (2.03±0.64) ng/mL) were higher than those in the control group, all with statistically significant differences (all P<0.01). Correlation analysis of executive function with monoamine neurotransmitters showed that serum dopamine level in the experimental group was correlated significantly with the number of correct 0-back, 2-back responses, correct response time, and TOH movement steps ( r=-0.194, 0.170, -0.163, 0.198, 0.196, all P<0.05), 5-hydroxytryptamine level was negatively correlated with the number of correct 0-back, 2-back responses( r=-0.267, -0.375), and was positively correlated with correct response time ( r=0.243, 0.177). Adrenaline content was significantly correlated with the number of correct 0-back and 2-back responses, correct response time, and the number of correct Stroop test responses, correct response time ( r=-0.340, 0.212, -0.415, 0.170, -0.212, 0.178, all P<0.05). Norepinephrine level was correlated significantly with the number of correct 0-back responses, correct response times, correct 2-back responses, correct Stroop test responses, and TOH movement steps ( r=-0.245, 0.266, -0.291, -0.193, 0.226, all P<0.05). Conclusion:The executive function of methamphetamine-dependent adolescents is damaged to a certain extent and the content of monoamine neurotransmitter in serum is increased.There is a correlation between impairment in executive function and serum levels of monoamine neurotransmitters.

Objective:To explore the effect of methamphetamine (MA) dependence on the attention of female youth, and to analyze the intervention effect of computer-based cognitive training on the attention of MA-dependent female youth.Method:From May to August 2021, a total of 64 MA-dependent female youths in abstinence period from a women's compulsory isolated drug rehabilitation center in Sichuan Province were selected as the MA group, and 53 ordinary female youths matched with their age and education level were selected as the normal control group.According to the matching principle of age, education level, and attention pre-test scores, the subjects in MA-dependent group were divided into MA-dependent intervention group( n=30)and MA-dependent waiting group( n=34). CogniPlus cognitive training system was used to train the attention of subjects in MA-dependent intervention group( n=30), while the subjects in MA-dependent waiting group( n=34) and normal control group did not receive training.The Vienna Test System was used to collect the attention scores of all subjects.SPSS 20.0 analysis software was used for data processing.Statistical analysis was performed using independent samples t test and paired samples t test. Results:The MA-dependent group had significantly longer endogenous alertness, temporary alertness, and concentration response time ((275.61±47.79)ms, (268.63±51.41)ms, (444.08±134.40)ms) compared with the normal control group ((247.02±34.09)ms, (237.60±46.04)ms, (355.15±44.37)ms) ( t=3.767, 3.405, 4.976; all P<0.05). After attention training, the post-test reaction time of endogenous alertness, temporary alertness, and concentration ((264.10±38.98)ms, (251.67±38.06)ms, (352.03±65.70)ms) in the MA-dependent intervention group were significantly shorter than those in the MA-dependent waiting group ((323.18±83.28)ms, (302.74±82.75)ms, (402.76±74.34)ms) ( t=-3.702, -3.232, -2.876; all P<0.05). The post-test reaction time of temporary alertness and concentration in the MA-dependent intervention group ((251.67±38.06)ms, (352.03±65.70)ms)were shorter than those of the pre-test ((265.70±37.84)ms, (428.67±120.11)ms) ( t=2.179, 3.588; both P<0.05). The MA-dependent waiting group had a longer post-test reaction time of endogenous alertness and temporary alertness(323.18±83.28)ms, (302.74±82.75)ms) compared with the pre-test ((285.35±51.43)ms, (271.21±61.42)ms) ( t=-2.752, -2.664; both P<0.05) and the post-test reaction time of concentration ((402.76±74.34)ms) was shorter than that of the pre-test ((457.68±146.29)ms)( t=2.431, P<0.05). The MA-dependent intervention group had longer endogenous alertness, temporary alertness, and pre-test reaction time of concentration ((264.57±41.41)ms, (265.70±37.84)ms, (428.67±120.11)ms)compared with the normal control group( t=2.083, 2.841, 3.230; all P<0.05). The post-test of endogenous alertness ((264.10±38.98)ms) was longer than that of the normal control group ( t=2.082, P<0.05). Conclusion:The cognitive training based on the CogniPlus system has a certain effect on the attention maintenance or recovery of MA-dependent female youth.It can be used as an intervention measure for cognitive impairment of drug addicts and help them healthy return to society.
