For the past 25 years, she has focused on understanding and treating people who experience persistent, intense grief, which is now an official diagnosis called Prolonged Grief Disorder in the ICD-11 and DSM-5. She developed and tested Complicated Grief Therapy/Prolonged Grief Disorder Therapy; a short-term, strength-based intervention that helps foster adaptation to loss, and confirmed its efficacy in three large NIMH-funded studies. Shear is widely recognized for her work in bereavement, including both research and clinical awards and invited authorship of articles. Her work includes more than 330 peer-reviewed publications, and she has developed several widely used assessment instruments and a PGDT instruction manual.
