This book discusses the psychological traits associated with drug consumption through the statistical analysis of a new database with information on 1885 respondents and use of 18 drugs. After reviewing published works on the psychological profiles of drug users and describing the data mining and machine learning methods used, it demonstrates that the personality traits (five factor model, impulsivity, and sensation seeking) together with simple demographic data make it possible to predict the risk of consumption of individual drugs with a sensitivity and specificity above 70% for most drugs.…mehr
This book discusses the psychological traits associated with drug consumption through the statistical analysis of a new database with information on 1885 respondents and use of 18 drugs. After reviewing published works on the psychological profiles of drug users and describing the data mining and machine learning methods used, it demonstrates that the personality traits (five factor model, impulsivity, and sensation seeking) together with simple demographic data make it possible to predict the risk of consumption of individual drugs with a sensitivity and specificity above 70% for most drugs. It also analyzes the correlations of use of different substances and describes the groups of drugs with correlated use, identifying significant differences in personality profiles for users of different drugs.
The book is intended for advanced undergraduates and first-year PhD students, as well as researchers and practitioners. Although no previous knowledge of machine learning, advanced data mining concepts or modern psychology of personality is assumed, familiarity with basic statistics and some experience in the use of probabilities would be helpful. For a more detailed introduction to statistical methods, the book provides recommendations for undergraduate textbooks.

Elaine Fehrman (BSc (Hons), BA DipSW, MSc, MBPsS) is employed as an HCPC-registered Advanced Practitioner at Rampton Hospital, which is one of three high secure hospitals in England and Wales. She is the substance misuse treatment clinical lead for the National High Secure Healthcare Service for Women at Rampton Hospital, and has several years of clinical practice experience working with offenders with mental health problems in low, medium, and high security hospitals, in the community, and in prison. She has a keen interest in improving the recovery and treatment outcomes for patients. Elaine is currently completing her Doctorate in Forensic Psychology, and is undertaking research to investigate the psychological sequelae of trauma in high risk mentally disordered offenders with substance misuse issues, and to determine if gender differences exist. The research will have important implications for informing treatment interventions at Rampton Hospital with this cohort with interrelated mental health issues.
