An OTR working in an outpatient setting has completed an initial evaluation with a client who has early state Parkinson's disease. The client has mild motor symptoms, scored within normal limits on the MoCA and reports independence with ADLs and IADLs. Medication management scores of the Performance Assessment of Self-Care Skills (PASS) are 2/3 for independence, 1/3 for safety, and 1/3 for adequacy. What does the discrepancy between the results of the PASS and the subjective report suggest about the client? 1) Intentional masking of changes in cognitive capacity 2) Confabulation during report of occupational abilities 3) Impaired self-awareness of performance errors
