Extended PMT model is proposed that includes the relationship of insiders' PsyCap. PsyCap uniquely relates to each threat and coping appraisal mechanism of PMT. Via the facets of PMT, PsyCap indirectly relates to protection motivation and PMBs. Higher levels of PsyCap are related to more PMBs and higher protection motivation. Opportunities exist to build insiders' PsyCap and improve information security.
