Parkinson’s Disease Impulsive-Compulsive Disorders Questionnaire – Current Short (QUIP-CS) – Translation and validation of content of Portuguese Version

Abstract

ABSTRACT Objective Parkinson’s disease (PD) management is usually successfully reached with proper pharmacological treatment. However, PD patients can manifest neuropsychiatric symptoms secondary to medical therapy, including impulse control disorders (ICD), presenting as pathological gambling, hypersexuality, compulsive buying, drinking or eating disorders. We translated and validated the Portuguese version of the gold-standard questionnaire Parkinson’s Disease Impulsive-Compulsive Disorders Questionnaire, or (QUIP) for identifying ICDs in PD patients. Methods Translation, back translation and submission to instrument developer was performed, that approved its new version comparing it to his original, validated version, with no loss of it’s original properties. Then, the Portuguese version was administered to 30 PD patients. They also were asked to rate from 1 to 5 the level of comprehensibility of the questions. Results The average level of comprehension was 4.06 ± 0.69 DP, considering 3 or more as acceptable. No patient has answered 1 or 2. Conclusion Our results on Portuguese version of QUIP-CS show that QUIP-CS translated and corrected version was easily understood and easily self-applied.
