Purpose: To develop a valid Cognition-oriented
Performance Evaluation (COPE) questionnaire for the
evaluation of higher brain function in any environment
using the nominal group technique (NGT).
Method: The NGT participants included nine expert
staff members of our hospital. The NGT process was
performed twice and involved: 1) enumerating
questions regarding the presence or absence of higher
cortical dysfunction symptoms, 2) judging each item
on a four-point scale and posing additional questions,
3) determining the level of agreement across
participants using the NGT, and 4) modifying,
removing, and adding questions based on the
agreement and comments of the NGT participants. In
addition, a correlation analysis between COPE areas
and the social cognition items of the Functional
Independence Measure (FIM) was performed in 20
patients with higher cortical dysfunction.
Results and discussion: An initial 126 questions were
crafted prior to the NGT. During the first NGT, 12
items failed to achieve adequate agreement, and during
the second NGT, three items failed. Furthermore, we
coordinated the expressed opinions after the second
NGT. The final version contained 96 items. Correlation
analysis demonstrated significant correlation between
the COPE and FIM in related items such as memory
and problem-solving. Thus, the validity of the COPE
was verified using a qualitative research technique
(consensus method) and by correlation with another
scale.
