Outline of Final Research Achievements

Our studies examined the association between motivation and drug-related recidivism via analyses of longitudinal recidivism data in addition to case studies and questionnaires regarding motivation. Interviews were conducted with professionals from treatment and support facilities in the community discussing how to facilitate collaboration with probation officers to promote drug users’ recovery. The results showed that higher motivation for amphetamine users to remain abstinent was significantly associated with lower drug-related recidivism, especially when observed in behavior rather than in verbal communication or self-report measures. Furthermore, the interview findings demonstrated that mutual understanding and respect between probation officers and professionals in the community are prerequisites for effective collaboration.

Academic Significance and Societal Importance of the Research Achievements

我が国では，欧米に比し，保護観察に付された覚醒剤事犯者の再犯を減少させうる，処遇内外の要因に関する研究が乏しい。こうした研究状況の中で，長期間の再犯データという，得難い貴重なデータの分析をはじめとした研究を実施し，覚醒剤事犯者の行動面に現れる動機づけと薬物再犯の関連を明らかにした本研究は，学術的に先進的なものであると位置づけられる。さらに，本研究は，地域における継続的サポートとその充実の重要性を指摘し，保護観察処遇における地域関係機関との連携上の留意点を具体的に論じており，覚醒剤事犯者の薬物再犯防止を目指した社会内処遇の発展のために，実践上及び社会的に高い意義を有する。
