The hypothesis proposed in this study is that there is an influence between self-efficacy, self-esteem, social support on resilience and optimism is a mediation. The subjects in this study amounted to 90   subjects who were MSME entrepreneurs. The sampling technique used is non-random incidental (incidental sampling).</em><em></em></p><p>  The research data was collected using five scales, namely the resilience scale, self-efficacy scale, self-esteem scale, social support scale, optimism scale and resilience scale. Data analysis was performed using SEM-PLS analysis with WarpPLS 7.0. The results showed that self-efficacy had an effect on resilience with a correlation coefficient of 0.18 with P=0.04 (&lt;0.05), self-efficacy had an effect on optimism with a correlation coefficient of 0.077 (P&lt;0.01). Optimism affects resilience with a correlation coefficient of 0.59 (P&lt; 0.01). Self esteem has no effect on resilience (P&gt;0.44) . Social support has no effect on resilience (P&gt;0.34) so that optimism fully mediates self-esteem and social support on resilience and optimism partially mediates self-efficacy on resilience.</p><p>Keywords : <em>self efficacy, self esteem, social support, optimisme and resilience</em><em></em></p><p><em>  </em></p></td></tr></tbody></table>
