    Addressing Collective Ambiguous Loss During These Tenuous Times

    Your Presenter: Cheryl Forster, Psy.D.

    Wednesday, June 10, 2026 @ 11:30 AM EDT

    The term “ambiguous loss” was coined by Dr. Pauline Boss in the 1970’s.  The original focus was on losses where there is an unclear loss with unclear resolutions (two types – physical absence coupled with psychological presence (e.g., adoption), or vice versa (e.g., dementia)), however, during the Covid-19 pandemic and after the murder of George Floyd, she expanded her conception of the term.  The expansion now includes personal ambiguous loss, that is either internally or externally caused, and ambiguous loss at the societal and global level.  We will explore Dr. Boss’ (2022) inclusion of the societal and global level, and the recommended guidelines for living with and healing ambiguous loss.  The guidelines will include some general cultural considerations as well – as interculturalists, we know that how grief and loss is addressed may vary across cultures.  In some ways, this webinar may differ from a typical SIETAR presentation.  However, if we think of the current sociopolitical context as a collective experience (even if we have different stances on it or relationships to it), acknowledging ambiguous loss and navigating it becomes an important component for many.  The guidelines do not lead to simple answers, but they may offer hope during these tenuous times.
