Translation, cross-cultural adaptation, and content validation of the Portuguese version of the Coping Behaviours Inventory (CBI) for the Brazilian population

Coping skills correlate directly with the success of alcohol abstinence. Brazil previously lacked an instrument to identify alcohol users' specific coping skills. The current study therefore aimed to perform the translation, cross-cultural adaptation, and content validation of the Coping Behaviours Inventory (CBI). Procedures included translation and back-translation, cross-cultural adaptation, content evaluation, and a pilot study. The final Portuguese version was administered by telephone to 40 alcohol users seeking help through a telephone hotline called VIVAVOZ. The retranslated version was close to the original. As for content validation, most of the items proved satisfactory and acceptable. The theoretical dimension showed a mean kappa index of 0.666 between evaluators, which was considered a substantial level of agreement. The results were satisfactory and acceptable, demonstrating that the inventory is appropriate for investigating coping skills in Brazilian alcohol users.
