In order to compare men's and women's screening behaviours, we collapsed the responses to these two questions and conducted a chi-square goodness of fit test. Several measures were used to assess the model fit: the Chi-square goodness of fit, the ratio of the Chi-square goodness of fit to the degrees of freedom, the root mean square error of approximation (RMSEA), the normed fit index (NFI), and the expected cross-validation index (ECVI). The goodness of fit of the models were assessed as recommended by Hosmer and Lemeshow (1989). |
