Abstract

Introduction

Impaired metacognition and impulsivity are critical factors in pathological gambling behavior subsistence. This study aims at jointly exploring metacognitive skills and impulsivity levels in subgroups of Parkinson’s Disease (PD) patients with different gambling status.

Method

48 PD participants were divided into three subgroups: PD Gamblers (PDG), PD patients with a previous history of gambling and PD controls. Impulsivity was assessed by the Barratt Impulsiveness Scale. After performing the Iowa Gambling Task (IGT), patients filled in a self-report measure to assess their metacognitive strategies.

Results

Findings highlighted that PDG showed higher levels of impulsivity than PD controls as reflected by clinical scales and behavioral measure. Also, PDG displayed a worse performance at IGT although they stated to use an efficacious strategy, suggesting then an erroneous metacognitive representation.

Conclusions

Overall findings proposed that high levels of impulsivity combined with an explicit metacognitive bias on self-efficacy could intervene in the persistence of pathological gambling behavior in PD patients.

有或没有赌博行为的帕金森病患者的元认知缺陷和冲动:一项初步研究

元认知和冲动性障碍是病态赌博行为生存的关键因素。本研究旨在探讨不同赌博状态帕金森病患者亚组元认知技能和冲动性水平。方法将48名PD参与者分为三个亚组:PD赌徒(PDG)、既往有赌博史的PD患者和PD对照组。冲动性采用Barratt冲动性量表进行评估。在完成爱荷华赌博任务(IGT)后，患者填写了一份自我报告来评估他们的元认知策略。结果临床量表和行为测量结果显示，PD组冲动水平高于PD对照组。此外，尽管PDG声称使用了有效的策略，但他们在IGT上的表现更差，这表明他们的元认知表征是错误的。结论高水平的冲动性与自我效能的外显元认知偏差可能干预PD患者病理性赌博行为的持续。

期刊介绍： Neurology, Psychiatry & Brain Research publishes original papers and reviews in biological psychiatry, brain research, neurology, neuropsychiatry, neuropsychoimmunology, psychopathology, psychotherapy. The journal has a focus on international and interdisciplinary basic research with clinical relevance. Translational research is particularly appreciated. Authors are allowed to submit their manuscript in their native language as supplemental data to the English version. Neurology, Psychiatry & Brain Research is related to the oldest German speaking journal in this field, the Centralblatt fur Nervenheilkunde, Psychiatrie und gerichtliche Psychopathologie, founded in 1878. The tradition and idea of previous famous editors (Alois Alzheimer and Kurt Schneider among others) was continued in modernized form with Neurology, Psychiatry & Brain Research. Centralblatt was a journal of broad scope and relevance, now Neurology, Psychiatry & Brain Research represents a journal with translational and interdisciplinary perspective, focusing on clinically oriented research in psychiatry, neurology and neighboring fields of neurosciences and psychology/psychotherapy with a preference for biologically oriented research including basic research. Preference is given for papers from newly emerging fields, like clinical psychoimmunology/neuroimmunology, and ideas.
