Cultural Adaptation and Psychometric Properties of the Persian Version of the Circumstances, Motivation, and Readiness Scale.
BACKGROUND
Treatment motivation has always been an important issue in substance abuse treatment. In recent decades, several instruments have been developed to measure this concept.


OBJECTIVE
In this study, cultural adaptation and psychometric properties of the Persian version of the circumstances, motivation and readiness scale (CMR) are illustrated in a sample of Iranian addicts.


METHODS
The translation process followed Beaton et al.'s (2000) guideline for the cross-cultural adaptation of self-administered questionnaires, including the steps of translation, synthesis, back translation, expert committee review, and pre-testing. The final version of the Persian CMR was assessed for internal consistency and construct validity (n = 203).


RESULTS
There was one eliminated item in the cross-cultural adaptation process. Also, four items that had low correlation with the total score were excluded from the questionnaire during the initial analysis. Using the remaining items, Principle axis factoring with Promax rotation was performed and three factors, circumstance, motivation, and readiness, were identified. The secondary order three factor model provided a good statistical and conceptual fit for the data. Internal consistency met the criterion for a reliable measure (Cronbach's alpha = 0.840). The α range for these identified factors was 0.597 to 0.837.


CONCLUSIONS
Although the CMR was originally designed for use in TC treatment, this study suggests that it is also applicable, with some modifications, in short-term residential camps. Also, it is concluded that the Persian translation of the CMR can be applied for studies among Persian addicts.
