    The Grief Evaluation Measure (GEM) is a new tool to assess complicated mourning in adults. It reliably and validly identifies risk factors and predicts long-term adjustment after bereavement.

    Area of Science:

    • Psychology
    • Clinical Assessment
    • Bereavement Studies

    Background:

    • Complicated mourning can significantly impact adult well-being.
    • Existing screening tools may not fully capture the complexity of grief responses.
    • A comprehensive measure is needed to identify at-risk bereaved individuals.

    Purpose of the Study:

    • To develop and validate the Grief Evaluation Measure (GEM) for screening complicated mourning.
    • To provide a quantitative and qualitative assessment of grief-related risk factors.
    • To evaluate the GEM's reliability and validity in diverse bereaved populations.

    Main Methods:

    • Development of the GEM instrument assessing risk factors, grief, and symptoms.
    • Reliability testing (internal consistency, test-retest) on two bereaved adult samples (n=23, n=92).

  • Validity testing (concurrent and predictive) against established measures and long-term adjustment.

    • Main Results:

    • The GEM demonstrated high internal consistency and test-retest reliability.
    • Concurrent validity was good for measures of bereavement, trauma, and psychiatric symptoms.
    • Predictive validity was good for predicting mourner adjustment one year post-assessment.

    Conclusions:

    • The Grief Evaluation Measure (GEM) is a reliable and valid instrument for screening complicated mourning.
    • The GEM effectively assesses risk factors and predicts future adjustment in bereaved adults.
    • Further research and collaboration on the GEM are encouraged for clinical application.
