“…As can be seen from Table 1, the review of the literature reveals that six ad hoc questionnaires have been used in quantitative studies (Williams and Nikolaisen, 1982;Price et al, 1985;Dyregrov and Matthiesen, 1987;Thuen, 1997;Irizarry and Willard, 1999;Goldstein et al, 2020). Of these six studies, three also used other instruments, such as the Impact of Event Scale (IES), the 20-item Goldberg General Health Questionnaire (GHQ-20), the State-Trait Anxiety Inventory (STAI), the Bodily Symptom Scale (BSS), the Beck Depression Inventory Short Form (BDI-SF) (Dyregrov and Matthiesen, 1987), the Symptom ChackList-90 and Bradburn's Affect-Balance Scale (Thuen, 1997), and the Parental Bereavement Questionnaire (PBQ) (Goldstein et al, 2020).…”
