Evidence pointing toward invalidity of the SF-8 physical and mental scales: a fusion validity assessment.

ABSTRACT:

Background

The SF-8™ Short Form Health Survey creates physical and mental health scale scores from responses to eight survey questions. These widely used scales demonstrate reasonable reliablity, and some forms of validity but have not been assessed for fusion validity. We assess the fusion validity of the SF-8 physical and mental health scales, and provide comments assisting fusion validity assessment of other scales.

Methods

Checking the fusion validity of a scale requires including the scale and its constituent indicators in a structural equation model that has at least one variable causally downstream from the scale. We assessed fusion validity of the SF-8 physical and mental health scales in the context of work-related variables for care aides working in Canadian long-t
