Risk of Relapse Assessment Scale for Metamphetamine Abusers: Reliability and Validity Study of the Turkish Version.

Area of Science:

• Psychiatry
• Addiction Medicine
• Psychometrics

Background:

• Methamphetamine use disorder is a significant public health concern.
• Assessing the risk of relapse is crucial for effective treatment and relapse prevention strategies.
• Validated assessment tools are needed to accurately identify individuals at high risk of relapse.

Purpose of the Study:

• To investigate the validity and reliability of the Turkish adaptation of the 16-item Risk of Relapse Assessment Scale (RRAS).
• To evaluate the RRAS's utility in Turkish methamphetamine abusers.
• To compare the RRAS with the Substance Craving Scale and Relapse Prediction Scale.

Main Methods:

• Exploratory and confirmatory factor analysis were used to assess the validity of the RRAS.
• Kaiser-Meyer-Olkin test and Barlett's test evaluated data suitability for factor analysis.
• Cronbach's alpha coefficient and corrected item-total correlation tested reliability.

Main Results:

• The Risk of Relapse Assessment Scale demonstrated strong internal consistency, with a Cronbach's alpha of 0.90.
• Subscale reliability ranged from 0.72 to 0.90.
• Goodness of fit indices indicated strong model fit for the RRAS in the Turkish population.

Conclusions:

• The Turkish adaptation of the RRAS is a valid and reliable instrument.
• The scale can be effectively used to assess relapse risk in Turkish individuals with methamphetamine use disorder.
• This tool aids in tailoring interventions for relapse prevention.
