Profiles associated with treatment retention in Japanese patients with methamphetamine use disorder: Preliminary survey

Abstract

Aims: To identify profiles associated with treatment retention in Japanese patients with methamphetamine use disorder. Methods: The study used a retrospective design based on clinical records. The subjects were 101 patients at the Kanagawa Psychiatric Center, Serigaya Hospital, who were diagnosed as having methamphetamine use disorder. They were divided in two groups, namely those who remained in treatment 3 months after the initial assessment, and those who did not. The primary analysis compared patient profiles between the two groups to detect discriminating variables, which were then submitted for secondary analysis using logistic regression to determine the most relevant predictor of retention. Results: Primary analysis indicated that older age, having psychotic symptoms, receiving public assistance, and history of incarceration were associated with treatment retention after 3 months. Secondary analysis showed that positive history of incarceration was the most significant predictor of the outcome. Conclusions: History of incarceration had the most significant treatment‐retention effect on Japanese patients with methamphetamine use disorder. The development and introduction of integrated programs that link methamphetamine‐dependent offenders to drug treatment is recommended in outpatient treatment for Japanese patients with methamphetamine user disorder.

Predictors of time to relapse in amphetamine-type substance users in the matrix treatment program in Iran: a Cox proportional hazard model application

“…None of the demographic variables were significant associated with relapse to ATS in this study While, some previous studies have shown associations between demographic variables and relapse to ATS [ 22 , 28 ], two other studies found results similar to our study. One explanation may be the spread of drug abuse among people with different age, occupation, education, and other backgrounds.…”

“…Relapse is not the result of a single factor and is usually caused by a combination of demographic and physiological characteristics, situational and socio-cultural features, and treatment characteristics [ 18 – 22 ]. While, most previous studies investigated correlates of relapse into drug use among opioid dependents [ 19 , 20 , 23 – 29 ], few studies focused on factors related to relapse among ATS users including demographic predictors such as age [ 22 , 28 ]; gender [ 30 ]; education attainment [ 22 ]; receiving social support [ 28 ]; patients’ psychological comorbidities [ 22 , 28 , 31 ]; history of prison [ 28 ]; and drug-use characteristics, such as age of starting ATS use [ 20 ], history of drug injection [ 32 ], selling substances [ 20 , 33 ], duration of lifetime ATS dependence [ 31 ], and treatment characteristics (including age of participating in treatment program [ 22 ] and type of treatment [ 12 , 20 , 34 ]). However, at this point there is no sufficient evidence for pattern of time to relapse among ATS users.…”

Clinical Course of Methamphetamine-Induced Psychotic Disorder in a 3-Month Follow-Up

“…To our knowledge, this is the first time that negative symptoms have been shown to be related to risk of relapse of substance use. In a study on retention of methamphetamine users in treatment, Kobayashi et al 40 showed that from among 4 potential predictors (age at initial assessment, presence of hallucinations, receiving public assistance, and history of incarceration), only history of incarceration could significantly predict treatment retention.…”

Psichosocial addictions treatment based on matrix model in a public center: a pilot study / Tratamiento psicosocial de las adicciones basado en el modelo matrix en un centro público: un estudio piloto

“…La retención terapéutica es comparativamente superior a la encontrada en estudios con otros tratamientos de la adicción a cocaína cognitivo-conductuales (Dutra et al, 2008;Higgins et al, 1993;Kobayashi et al, 2008;Sánchez Hervás et al, 2008) dado que en nuestro estudio 8 de los 9 pacientes terminaron el tratamiento completo de 4 meses. Uno de los puntos fuertes del tratamiento basado en el MM es su elevada estructuración e intensidad al comienzo, que ayuda a los pacientes a recuperar hábitos de vida saludables y mejora la retención.…”
