OBJECTIVES: To determine whether objective (neuropsychological tests) and
subjective measures (questionnaires) of executive functions (EFs) are associated
in patients with Parkinson disease (PD), and to determine to what extent level of
participation and quality of life (QoL) of patients with PD can be predicted by
these measures of EFs. DESIGN: Correlational research design (case-control and
prediction design). SETTING: Departments of neuropsychology of 3 medical centers.
PARTICIPANTS: A sample (N=136) of patients with PD (n=42) and their relatives,
and controls without PD (n=94). INTERVENTIONS: Not applicable. MAIN OUTCOME
MEASURES: A test battery measuring EFs. In addition, patients, their relatives,
and controls completed the Dysexecutive Questionnaire, Brock Adaptive Functioning
Questionnaire, and Barkley Deficits in Executive Functioning Scale - time
management questionnaires measuring complaints about EFs. Participation and QoL
were measured with the Impact on Participation and Autonomy scale and the
Parkinson's Disease Questionnaire-39, respectively. RESULTS: Patients with PD
showed impairments in EFs on objective tests and reported significantly more
complaints about EFs than did controls without PD. No associations were found
between patients' performances on objective and subjective measures of EFs.
However, both objective and subjective measures predicted patients' level of
participation. In addition, subjective measures of EFs predicted QoL in patients
with PD. CONCLUSIONS: These findings show that objective and subjective measures
of EFs are not interchangeable and that both approaches predict level of
participation and QoL in patients with PD. However, within this context, sex
needs to be taken into account.
