A crucial prerequisite to the use of the SF-36 Health Survey in multinational studies is the reproduction of the conceptual model underlying its scoring and interpretation.
Structural equation modeling (SEM) was used to test these aspects of the construct validity of the SF-36 in ten IQOLA countries :
Italy, the Netherlands,
Sweden, the United Kingdom, and the United States.
Data came from general population surveys fielded to gather normative data.
Measurement and structural models developed in the United States were cross-validated in random halves of the sample in each country.
SEM analyses supported the eight first-order factor model of health that underlies the scoring of SF-36 scales and two second-order factors that are the basis for summary physical and mental health measures.
A single third-order factor was also observed in support of the hypothesis that all responses to the SF-36 are generated by a single, underlying construct-health.
In addition, a third second-order factors, interpreted as general well-being, was shown to improve the fit of the model.
This model (including eight first-order factors, three second-order factors, and one third-order factor) was cross-validated using a holdout sample within the United States and in each of the nine other countries.
These results confirm the hypothesized relationships between SF-36 items and scales and justify their scoring in each country using standard algorithms. (...)
