title: [Effectiveness of brief intervention for substance use disorder in Japan--a pilot study].
abstract: BACKGROUND
  Relatively few hospitals can treat substance use disorder in Japan and the options for treatment are limited. Previous studies in the West have shown the effectiveness of brief intervention for substance use disorder. However, such treatment has not been sufficiently implemented in Japan. For this study, we developed brief intervention tools for substance use disorder, and conducted a pilot study to evaluate the efficacy of treatment.
  
  
  METHODS
  Participants in this study were recruited from those admitted for substance use disorder in the addiction treatment unit of Tokyo Metropolitan Matsuzawa Hospital, and the recruitment period was from October 2013 through March 2014. The brief intervention consisted of one 30-min individual session. Four self-rating scales measuring motivation, relapse risk and self-efficacy were administered pre- and post-intervention: SOCRATES-8D, Stimulants Relapse Risk Scale, Drug Abuse Self-efficacy Scale and Visual Analogue Scale.
  
  
  RESULTS
  Forty patients participated in this study. Subscale Scores at post-intervention that improved significantly compared to those at pre-intervention were Recognition (SOCRATES-8D); Total score and Anxiety and intention to use drug (Stimulants Relapse Risk Scale); Generalized self-efficacy (Drug Abuse Self-efficacy Scale); and Knowledge about drug abuse (Visual Analogue Scale).
  
  
  CONCLUSIONS
  These results indicate that brief interventions may offer effective treatment for substance use disorder. A randomized controlled trial that contains an evaluation of abstinence rate in the follow-up period is needed to ascertain the efficacy of brief intervention for substance use disorder in Japan.
