As shown, R –Square is higher than .80 for all components. In addition,
the value of Q2 is more than .35 for all terms which
means that the model has a large size of predictive relevance
considering the support, normalization, and participation factors.
The goodness of fit is a measure of model fit in PLS, which is a
compound of effect size with convergent validity. It varies from 0 to 1.
In the present study, Model fit was confirmed by the GoF index which was
0.694. Therefore, the Family Disease Management Questionnaire consists
of supports: normalization and participation.
