Abstract

The Texas Revised Inventory of Grief (TRIG) was developed to measure the intensity of grief after the death of a close person. It consists of two scales: TRIG I (past behaviors) and TRIG II (present feelings). Because of inconsistencies in previous validations, the instrument needs to be further validated, hence the aim of this study was to evaluate the psychometric properties of the TRIG in a sample of bereaved family caregivers in Sweden. The TRIG was translated to Swedish according to standard principles, and 129 bereaved family caregivers completed the questionnaire. Parallel analysis was used to decide the number of factors to extract, followed by confirmatory factor analysis. An ordinal version of Cronbach's alpha was used to... (More)

The Texas Revised Inventory of Grief (TRIG) was developed to measure the intensity of grief after the death of a close person. It consists of two scales: TRIG I (past behaviors) and TRIG II (present feelings). Because of inconsistencies in previous validations, the instrument needs to be further validated, hence the aim of this study was to evaluate the psychometric properties of the TRIG in a sample of bereaved family caregivers in Sweden. The TRIG was translated to Swedish according to standard principles, and 129 bereaved family caregivers completed the questionnaire. Parallel analysis was used to decide the number of factors to extract, followed by confirmatory factor analysis. An ordinal version of Cronbach's alpha was used to evaluate the internal consistency of the scales. Construct validity was tested against the Hospital Anxiety and Depression Scale (HADS). The factor analyses resulted in one factor being retained for both scales. The internal consistency was excellent (α > 0.9) for both scales. Construct validity was supported by strong correlations between TRIG I and TRIG II as well as moderate correlations between the TRIG scales and HADS. In conclusion, the TRIG has sound psychometric qualities and the two scales should be treated as unidimensional measures of grief. Hence, the instrument is suited to be used in the context of palliative care.
