Since the questionnaire relies on client self-report, all responses should be verified by the clinician, and a definitive diagnosis is made on clinical grounds taking into account how well the client understood the questionnaire, as well as other relevant information from the client.
Psychometric properties and interpretation:
The PGRF was developed on a large sample of adults (N = 831) who lost a significant person to COVID-19. The PGRF is a reliable instrument (α = .88), with solid factorial (single-factor) and construct validity (correlates with measures of dysfunctional pandemic-related grief symptoms and functional impairment). Each item of the PGRF is rated on a 4-point scale, from 0 (not at all) to 3 (nearly every day), based on experiences over the past two weeks. Elevated scores on a particular item or a high total scale score indicate problematic symptoms or struggles for the individual that could warrant further assessment and/or treatment. Clinical judgement should guide the interpretation of the PGRF results. vs Score)
