<h3>About the Inventory of Complicated Grief (ICG)</h3>
<div class="info-box">
The <strong>Inventory of Complicated Grief (ICG)</strong> is a widely used self-report questionnaire designed to assess prolonged grief reactions, emotional distress after bereavement, separation-related distress, and difficulties adapting following the death of a loved one.
</div>
<div class="info-box">
The ICG was developed by <strong>Holly G. Prigerson</strong> and colleagues during the 1990s to identify symptoms associated with complicated grief, persistent grief reactions, and prolonged bereavement-related emotional difficulties.
</div>
<div class="info-box">
The questionnaire evaluates emotional pain, longing, disbelief, emotional numbness, social withdrawal, grief-related distress, bitterness, loneliness, and difficulty adjusting after loss.
</div>
<div class="info-box">
Research studies have demonstrated strong reliability and validity for the ICG across grief research, bereavement counseling, trauma studies, psychiatry, palliative care, and mental health settings.
