• The GIS is a mental health screening tool designed to quickly and accurately identify bereaved adults who are experiencing clinically significant impairment because of their grief. 

• The GIS is based on the biopsychosocial model of illness, which views disorders from multiple levels of human functioning. Specifically, the GIS measures grief-related impairment in the biological domain (i.e., health problems), two aspects of the psychological domain, which are the behavioral (i.e., unhealthy coping) and the cognitive (i.e., thinking difficulties) domains, as well as the social domain (i.e., positive engagement difficulties). 

• Good instrument for clinicians, researchers, and educators interested in measuring grief-related problems. 

• Normative data were collected on 363 bereaved adults who were struggling with grief over the death of significant people in their lives.

• The GIS consists of five items, requiring a few minutes to complete and score.

• The GIS provides an empirically derived cut-off score to determine probable grief-related impairment.

• The GIS allows respondents to identify their own impairments within each category of functioning so that their results more accurately reflect their unique, grief-related difficulties. 

• The GIS measures impairment frequencies across a 30-day period, which facilitates diagnostic assessment, goal-setting, treatment planning, and epidemiological analysis.

• Strong reliability (ωs from 0.80 to 0.88).

• Solid unidimensional factor structure (CFIs from 0.97 to 1.00).

• Measurement invariance across demographic groups.

• Cross-cultural validity (South American countries and Iran)

• Solid diagnostic efficacy (79% sensitivity and 74% specificity).

• Good discrimination values for each GIS item (IRT analysis).

• Strong convergent and divergent validity (correlates with impairment, prolonged grief, and psychological distress).

• GIS items are rated on a 5-point scale, from 0 [0 days (never)] to 4 [30 days (nearly every day)], based on experiences over the past 30 days.

• A GIS total score of 9 and greater indicate probable functional impairment due to grief.

• Elevated scores on a particular GIS item or a high total scale score (≥ 9) may indicate problematic symptoms for the individual that might warrant further assessment and/or treatment. 

• Clinical judgement should guide the interpretation of the GIS results.
