Objectives The aims of the study were to determine targeted parent experiences of parental alienation post‐separation from the alienating parent, and to investigate common targeted parent characteristics. Method A total of 225 targeted parents completed an online survey. Results Targeted parents reported experiencing high severity of exposure to parental alienation tactics. Targeted parent sex and targeted child age significantly predicted variance in exposure to parental alienation. Targeted mothers experienced significantly higher severity of exposure to parental alienation than targeted fathers. Severity of exposure to parental alienation tactics significantly predicted increases in the appraisal of the parental alienation situation as threatening. Conclusions The findings offered new insights into targeted parent appraisals of their parental alienation experience. The results signified the seriousness of the impact of exposure to parental alienation for targeted parents, and highlighted a need for empirical research into the effectiveness of interventions and support services to assist targeted parents.
