Causal and mutual relationships with FAMS mobility score. Increases in EDSS and availability of sources of disease information scores directly reduce the FAMS mobility score. The standardized total effect of EDSS on FAMS mobility score is -.76, which consists of a standardized direct effect of -.69 and a standardized indirect effect of -.07. Scores for changes in employment status and EDSS have a negative influence on the NAS-J anxiety/depression and acceptance scores. In contrast, knowledge of disease information scores positively affects the NAS-J anxiety/depression and acceptance scores. These three factors thus indirectly affect the FAMS mobility score through the NAS-J anxiety/depression and acceptance scores. d1, e1, e2, and e3 in the figure are error terms. Numbers are standardized path coefficients, and asterisks (*) indicate statistical significance (p < 0.05).
