Translation and cross-cultural adaptation into Brazilian Portuguese of the Measure of Parental Style (MOPS)--a self-reported scale--according to the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) recommendations.

Objective: To describe the translation and adaptation methodology for the Measure of Parental Style, a self-report instrument developed originally in English, following the International Society for Pharmacoeconomics and Outcomes Research guidelines, comparing this to other methodologies used for the same purposes.

Method: Translation and Cultural Adaptation group International Society for Pharmacoeconomics and Outcomes Research guidelines were followed (preparation, first forward translation, reconciliation, back translation, revision of back translation, harmonization, cognitive debriefing, revision of debriefing results, syntax and orthographic revision, final report).

Presenting this process, besides its final product, provides the opportunity that this experience could be replicated for adaptation of other instruments.
