Impulse control disorders in Parkinson’s disease: A systematic review on the psychometric properties of the existing measures

Abstract

Background A significant percentage of patients suffering from Parkinson’s Disease (PD) experience Impulse Control Disorders (ICDs), contributing to reduced quality of life. As they can be managed by reducing the dopamine dosage, the detection of their presence is crucial for PD treatment plan. Nevertheless, they tend to be under-recognized in clinical practice, since routine screening is not common–despite existing instruments that may support clinicians. This work presents a systematic review on the psychometric properties of instruments measuring ICDs in PD, to test whether clinicians dispose of valid tools that may help them in clinical assessment. Method A systematic literature search in three databases (EMBASE, MEDLINE, and PsycINFO) was conducted. Quality of the instruments’ psychometric properties was evaluated with Terwee et al.’s criteria, and methodological quality of the studies was evaluated with the COSMIN Checklist. Results Ten studies examining seven instruments were selected. The Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease (QUIP) and the Ardouin Scale of Behavior in Parkinson’s Disease (ASBPD) resulted to be the best from a psychometric point of view. Conclusions Though the gold standard for diagnosis remains a detailed diagnostic interview, this review will encourage clinicians to use validated tools to accurately assess ICDs.

Clinical practice guidelines based on evidence for cognitive‐behavioural therapy in Parkinson's disease comorbidities: A literature review

“…It is important to keep in mind that not all ICD in patients are induced by medications, and those cases are perfectly suitable for psychological interventions. ICD and related disorders are socially inappropriate; they interrupt everyday activities and quality of life of patients, and they can have even greater negative impact on social life of patients (i.e., isolating themselves even more), so it is of priority to recognize it early, use preventive measures, and introduce them into psychological treatment (Izzo, Donati, Ramat, & Primi, 2019). Neurologists and primary physicians usually cannot recognize from the beginning triggering factors such as medication dosage, and they can misinterpret behavioural problems as normal changes or as a primary psychiatric disorder, while in truth, problems are possibly induced by dopaminergic therapy (Molde et al, 2018).…”

Tradução e validação para o português de uma escala de avaliação de transtornos de controle de impulso em pacientes com doença de parkinson no Brasil

“…As análises de item são descritas na Tabela 3. O alfa de Cronbach da escala foi de 0.79, sendo considerado aceitável entre 0.70 e 0.90, completando a confirmação da confiabilidade da escala (IZZO, 2019). Tal parâmetro determina a consistência interna da escala, representando que esta possui questões que acessam um mesmo assunto (PEACOCK, 2011).…”

“…Já a confiabilidade inter-avaliador visa demonstrar se a escala quando aplicada por diferentes avaliadores, igualmente treinados, revela os mesmos resultados (DE ANDRADE MARTINS, 2006). Apesar disso, a QUIP original e a QUIP-CS foram validadas sem tais testes, e a própria QUIP-RS foi validada para outras línguas, como para o Alemão e para a população coreana, sem a avaliação da confiabilidade interavaliador (IZZO, 2019;CHOI, 2020). Assim, pode-se considerar que os testes mencionados não são fundamentais para a validação de uma escala, portanto, sua ausência não diminui a relevância do presente estudo.…”

Impulse control disorder in the patients of Parkinson’s disease: various correlations

“…So it will be good to identify ICDs in patients of Parkinson disease to make therapeutic decisions and avoiding important social, economic and legal problems for patients. 16,17 Younger and masculine preponderance in control group might be the reason behind more addiction pattern-with time and age, these issues are usually resolved or at least minimised. Zhang et al study compared two groups of PD instead -one with manifest ICD and other without in which earlier onset of the disease, higher dose of dopamine agonist, severe cognitive impairment and dyskinesia were independent risk factors associated with impulse control related disorders (ICRDs).…”
