Proposal for updating the Health Assessment Questionnaire.

OBJECTIVE: To propose a consensus modification of the HAQ according to the predominant values, language, and culture of the society. METHODS: First, a scoping review of the literature and a survey of HAQ users were conducted to identify the problems of this questionnaire. In a second phase, a meeting was held with expert professionals to discuss the results and design proposals for modification. RESULTS: The scoping review allowed us to describe the main versions of the HAQ, as well as their psychometric properties. The HAQ users survey assessed the degree of comprehension, usefulness, timeliness, and universality of each of the items, and suggestions and opinions on its main limitations were accepted. During the discussion meeting, modifications to the items were proposed based on the results of the scoping review and the users survey. In addition, the difficulty of understanding the items, their difficulty in assessing intended movements, redundancy, obsolescence, and possible gender bias were taken into account. CONCLUSIONS: An update of the Spanish version of the HAQ is proposed based on the literature review and expert opinion that highlights the paradigm shift in cultural values and aims to increase the content validity and discrimination capacity of this questionnaire.
