MS patient self-efficacy scale
SCHWARTZ
This scale was developed by Rigby et al. in 2003 in England to assess the self-efficacy of adult patients with MS. It is a multi-dimensional and self-report instrument developed with 14 items.

In the study of Rigby et al., the correlation between the score of the participants in this tool and the Schwartz general self-efficacy scale was reported 0.64, which indicates the validity of this tool. The reliability of this tool was confirmed through test–retest (r = 0.081,
