Predicted growth curve model for overall risk scores on the eight-item (Panel A) and three-item (Panel B) Montreal Parkinson Risk of Dementia Scale (MoPaRDS). Baseline overall risk scores on the eight-item MoPaRDS statistically differed across participants (σ̂2 = 1.65, p < .001). Overall risk scores on the eight-item MoPaRDS increased across the three waves (M increase per wave = 0.30, p = .002). Baseline overall risk scores on the three-item MoPaRDS statistically differed across participants (σ̂2 = 0.70, p < .001). Overall risk scores on the three-item MoPaRDS increased across the three waves (M increase per wave = 0.23, p < .001).
