Cognitive Strategy Use During the Weekly Calendar Planning Activity in People With Parkinson's Disease

Cognitive impairment is common among people with Parkinson's disease (PwPD) without dementia and is related to reduced performance, participation and quality of life. Understanding how PwPD use strategies to support their cognitive performance can help therapists design targeted and effective interventions. This study investigated strategy use and effectiveness during a functional cognitive task among PwPD. Data are from the pre-treatment assessment of a randomized controlled trial of a metacognitive strategy intervention (Multicontext Approach) in PwPD. Participants (N=54) were PwPD without dementia but with subjective cognitive decline. They completed the Level II Adult/Older Adult Weekly Calendar Planning Activity. Strategy use, accuracy, completion time, and efficiency were assessed. Spearman rho and Mann-Whitney U tests were used; p
