Punding, one of these nonmotor problems, is a term used to describe complex, purposeless stereotyped behaviors such as the repetitive handling or sorting of objects. A self\u2010report questionnaire was adapted to assess punding in the context of dysfunctional hobby\u2010related activities. We report the results of a survey of PD outpatients from a PD research clinic (n = 141) and non\u2010PD controls (n = 103); conducted to identify clinical and psychological factors predictive of punding behaviors. The PD group reported hobbies and activities, which scored significantly higher on the Punding Scale than controls. Higher impulsivity, poorer disease\u2010related quality of life, younger age of disease onset, and concomitant daily medication dosage from dopamine receptor agonists were independently predictive of higher Punding Scale scores in the PD group. These findings are similar to those seen in dopamine dysregulation syndrome, and provide further evidence for the role of impulsivity and age at disease onset in DRT\u2010related nonmotor behavioral problems in PD. \u00a9 2007 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.21702","type":"journal-article","created":{"date-parts":[[2007,10,3]],"date-time":"2007-10-03T13:48:10Z","timestamp":1191419290000},"page":"2339-2345","source":"Crossref","is-referenced-by-count":52,"title":["Predictors of punding in Parkinson's disease: Results from a questionnaire survey"],"prefix":"10.1002","volume":"22","author":[{"given":"Andrew J.","family":"Lawrence","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew D.","family":"Blackwell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roger A.","family":"Barker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca","family":"Spagnolo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luke","family":"Clark","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael R.
