Background:
This study aims to investigate the validity and reliability of the Turkish adaptation of the 16-item Risk of Relapse Assessment Scale (RRAS) for methamphetamine abusers.
Methods:
A total of 160 patients diagnosed with methamphetamine use disorder were included in this study to evaluate the validity and reliability of the scale. The comparison of the relationship between the Risk of Relapse Assessment Scale, the Substance Craving Scale, and the Relapse Prediction Scale was also carried out. The validity of the Risk of Relapse Assessment Scale was examined in the first step by exploratory factor analysis. The suitability of the data for exploratory factor analysis was evaluated by Kaiser-Meyer-Olkin test and Barlett's test. Cronbach's α coefficient and corrected item-total correlation value were used to test the reliability of the scale. The validity results of Risk of Relapse Assessment Scale were tested by confirmatory factor analysis. The significance level was set at P < .05 for all analyses.
Results:
Considering the examination of the internal consistency values of the Risk of Relapse Assessment Scale, Cronbach's α value was detected to be 0.90, and Cronbach's α value of the subscales ranged from 0.72 to 0.90. The study determined that the goodness of fit values for RRAS were χ 2/df =2.13, P < .001, goodness of fit index = 0.88, comparative fit index = 0.92, normed fit index = 0.86, Trucker-Lewis index = 0.90, root mean square error of approximation = 0.08, and standardized root mean squared residual = 0.06.
Conclusion:
Our findings demonstrate that Risk of Relapse Assessment Scale is a valid and reliable measurement tool for assessing the risk of methamphetamine relapse in Turkish.
Insights
The Turkish adaptation of the Risk of Relapse Assessment Scale (RRAS) is a valid and reliable tool for assessing methamphetamine relapse risk. This study confirms its utility in Turkish methamphetamine abusers.
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.
