The Self-Administered Screening Questionnaire for Parkinson's Disease-Associated Psychosis (SASPAP).

BACKGROUND: Psychosis is a common manifestation of Parkinson's disease (PD), and a major source of caregiver burden, nursing home placement, and mortality. Psychosis symptoms are often not volunteered during the clinic visit because of embarrassment or lack of insight, and there is no validated screening scale. We compare a new self-administered psychosis screening questionnaire against the Parkinson's Disease Psychosis Scale (PDPS) and physician interview as the gold standard assessments. OBJECTIVE: To create and validate the Self-Administered Screening Questionnaire for PD-Associated Psychosis (SASPAP). METHODS: The questionnaire was developed through a modified Delphi method by a committee of two neurologists, a psychiatrist, a patient, and patient advocate and underwent several rounds of revisions, including patient ß-testing. It was provided by staff at intake to 250 consecutive patients diagnosed with PD, at the Methodist Hospital Movement Disorders Clinic, and separately to their caregivers when available. Later, the PDPS and a general psychosis interview were administered by PD specialists without knowledge of the screening questionnaire responses. RESULTS: Two hundred and fifty consecutive patients with PD (mean age, 68.6 ± 7.0; mean age of PD onset, 62.7 ± 10.5 years; 35.2% female) were included. The screening questionnaire was positive for psychosis (any of the four questions positive) in 33.6% of patients. Compared to the gold standard, the SASPAP sensitivity was 87.8% and the specificity 92.3%. CONCLUSION: This four-question self-administered screening questionnaire for PD psychosis demonstrated high diagnostic accuracy compared with the gold standard assessments and can be self-completed at visit intake. © 2023 International Parkinson and Movement Disorder Society.

Comparative Patient Satisfaction and Feasibility of a Pilot Parkinson's Disease Enrichment Program.

BACKGROUND: Available treatment options for Parkinson's disease (PD) are primarily aimed at pharmacological and/or neurosurgical management of motor symptoms. However, many patients also experience chronic non-motor symptoms (NMS), including significant cognitive and mood changes. Currently, there is a gap in the neuropsychological literature regarding the efficacy of nonpharmacological treatment options for cognitive and mood changes in PD. OBJECTIVE: We sought to evaluate the efficacy and patient satisfaction of a pilot nonpharmacological intervention for alleviating NMS in patients with PD. METHODS: Twenty-three independently functioning nondemented patients with PD participated in a 5-week Parkinson's Disease Enrichment Program. Each 4-hour weekly session included content which addressed the following components: education, exercise, recreation, and socialization/support. Participants received a pre-assessment, including cognitive tests and questionnaires for depression and quality of life. After the completion of the program, participants completed post-assessment batteries to measure changes in neurocognitive and psychiatric status, as well as patient satisfaction regarding the program. RESULTS: Neuropsychological data from pre- and post-assessments revealed significant improvements in measures of executive functioning, memory, and depressive symptoms. No significant changes were observed on the remaining mood or cognitive measures. One hundred percent of participants reported enjoyment from socialization with other participants with PD and satisfaction with the program overall. CONCLUSIONS: Positive preliminary results suggest that further expansion of this nonpharmacological pilot program for treatment of NMS may be beneficial for patients with PD. Future studies will investigate a larger cohort of participants with PD and cross-validate findings in demographically diverse samples.
