BACKGROUND AND PURPOSE: There are limited reliable and valid measures of the patient- provider interaction among adults with hypertension. Therefore, the purpose of this report is to describe the construct validity and reliability of the Questionnaire on the Quality of Physician-Patient Interaction (QQPPI), in community-dwelling adults with hypertension.
METHODS: A convenience sample of 109 participants with hypertension was recruited and administered the QQPPI at baseline and 8 weeks later.
RESULTS: The exploratory factor analysis established a 12-item, 2-factor structure for the QQPPI was valid in this sample. The modified QQPPI proved to have sufficient internal consistency and test- retest reliability.
CONCLUSIONS: The modified QQPPI is a valid and reliable measure of the provider-patient interaction, a construct posited to impact self-management, in adults with hypertension.
