Testing the Factorial Validity of Scores From the Caregiver Pain Medicine Questionnaire
Journal of Pain and Symptom Management

Abstract
Context
The
Caregiver Pain Medicine Questionnaire is designed to measure caregiver
agreement with statements regarding pain management. However, little
testing has been done to determine its reliability and validity.
Objectives
The
objective of the study was to test the factorial validity of scores
from the Caregiver Pain Medicine Questionnaire as hypothesized by the
original study authors.
Methods
Confirmatory factor
analysis was conducted to assess whether the subscales postulated by the
instrument authors could be replicated in external data.
Results
Fit statistics reveal an unsatisfactory fit between the hypothesized model and the observed data.
Conclusion
The
theoretical model hypothesized by the original study authors was not
confirmed. Results lead us to conclude that the instrument is poor
and should not be used. Further research is needed to define content
domains and validate the items developed to assess them.
