The Mediated Effect of Self-Efficacy on Participation Frequency

Factor	path a_i	path b_i	a_ib_i	95% CI^*
Life-space mobility	0.36	0.12	0.04	0.02, 0.08
Wheelchair skills	0.63	0.04	0.03	−0.05, 0.10
Participation limitations	0.29	0.23	0.07	0.02, 0.13
Total mediated effect			0.14	0.04, 0.24
Proportion of the direct effect accounted for by the mediators	0.14/0.18 = 0.78
adj R²	55.0%

1000 bootstrap samples; CI = confidence interval path a_i = the associations between self-efficacy and the mediators; path b_i = the associations between the mediators and participation frequency; a_ib_i = the magnitude of each mediated effect.
