Purpose: To examine the cross-cultural applicability of the Communicative Participation Item Bank (CPIB) through a comparison of respondents with Parkinson's disease (PD) from the United States and New Zealand. Method: A total of 428 respondents--218 from the United States and 210 from New Zealand-completed the self-report CPIB and a series of demographic questions. Differential item functioning (DIF) analyses were conducted to examine whether response bias was present across the 2 groups. Results: No items were identified as having statistically significant DIF across the U.S. and N.Z. cohorts. Conclusion: The current CPIB items and scoring parameters are also suitable for use with respondents from New Zealand.
