NCT04139148

Brief Summary

Transcranial direct current stimulation (tDCS) combined with computerized cognitive addiction therapy(CCAT) for methamphetamine(MA) dependent patients in voluntary drug rehabilitation center. Electronic medical systems were applied for drug related knowledge education, self-evaluation and outpatient follow-up reminder after intervention in order to reduce relapse behaviors.

Outcome Measures

Primary Outcomes (2)

  • Change from Baseline cue-induced craving at 2 weeks

    Participants were instructed to watch methamphetamine-related videos by VR and rate their level of craving after smelling and recalling the last time they engaged in drug use. Craving was assessed by visual analog scales (VAS), with 0 mm being "no craving"and 100 mm representing "most craving ever experienced for methamphetamine".

    2 weeks

  • Change from Baseline cue-induced craving at 4 weeks

    Participants were instructed to watch methamphetamine-related videos by VR and rate their level of craving after smelling and recalling the last time they engaged in drug use. Craving was assessed by visual analog scales (VAS), with 0 mm being "no craving"and 100 mm representing "most craving ever experienced for methamphetamine".

    4 weeks

Secondary Outcomes (4)

  • Attention bias towards methamphetamine

    2 weeks,4 weeks

  • cognitive function

    2 weeks,4 weeks

  • response inhibition function

    2 weeks,4 weeks

  • reward-related function

    2 weeks,4 weeks

Study Arms (3)

True tDCS Combined With CCAT

ACTIVE COMPARATOR

Ture transcranial direct current stimulation (tDCS) intervention combined with computerized cognitive addiction therapy(CCAT) group, last 25 minutes per day for 4 weeks(5 days/week). Electronic follow-up for 6 month including drug knowledge every week, self-evaluation every two weeks and outpatient follow-up reminder every four weeks.

Device: Ture Transcranial Direct Current Stimulation (tDCS)

Sham tDCS Combined With CCAT

SHAM COMPARATOR

Sham transcranial direct current stimulation (tDCS) intervention combined with computerized cognitive addiction therapy(CCAT) group, last 25 minutes per day for 4 weeks(5 days/week). Electronic follow-up for 6 month including only outpatient follow-up reminder every four weeks.

Device: Sham Transcranial Direct Current Stimulation (tDCS)

Control group

NO INTERVENTION

During the treatment, the participants in control group only received treatment such as education of psychology, health and judicature, physical training as well as vocational training as usual in the compulsory rehabilitation center.

Interventions

Ture 1-2 mA current of tDCS intervention in patients' binary brain DLPFC areas(20 mm).

True tDCS Combined With CCAT

Sham tDCS intervention in patients' binary brain DLPFC areas(20 mm).

Sham tDCS Combined With CCAT
