Predictors of Clinical Outcomes in IADC Therapy

(1) Background: Induced After-Death Communication (IADC) therapy is a brief intervention facilitating grief resolution through a perceived experience of communication with the deceased. Despite growing evidence of its efficacy, little is known about which individual characteristics may influence treatment responsiveness. (2) Methods: This pre–post study investigated psychological predictors of IADC outcomes in 73 bereaved adults. Standardized measures assessed grief severity, alexithymia, dissociation, attachment dimensions, and Big Five personality traits. Changes in grief-related distress and continuing bonds were analyzed using paired-sample t-tests and hierarchical regressions. (3) Results: IADC therapy produced substantial reductions in grief-related distress and enhanced continuing bonds. Dissociation, demographic variables, and most personality traits were unrelated to outcomes. Neuroticism showed a marginally negative association, whereas Openness predicted greater improvement. Alexithymia negatively predicted clinical gains, suggesting that limited emotional awareness may interfere with the therapeutic phase of abreaction and, in turn, limit access to the receptive state. Among attachment dimensions, only Need for Approval significantly predicted poorer outcomes, consistent with performance anxiety and self-evaluative control interfering with spontaneous mental processes. (4) Conclusions: IADC therapy appears highly effective across diverse individual profiles. Screening for alexithymia and Need for Approval may help identify these potential sources of therapeutic failure and be followed by targeted strategies aimed at counteracting their impact and mitigating their effects.
