Version 1: Original translation developed by Lelorain et al. | See Lelorain et al. [11] Sample: N = 307 Long term Breast cancer survivors (France) | RO: 0.85 NP: 0.86 SC: 0.83 AL: 0.81 PS: 0.79 Total PTGI (21 items): 0.93 | Not available | Hierarchical CFA with 5 first-order factors (one for each domain) and one second-order factor (global PTG) The model did not fit their data well | Not avaible | Not available | No | - Three studies used this version to assess PTG in breast cancer patients [11, 24, 25] - One study used this version to validate the French translation-adaptation of the impact of cancer questionnaire version 2 (VALIOC) [26] - One study used this version to assess PTG in survivors of intimate partner violence [13] |
Version 2:Revised version based on the translation of Lelorain et al. | No | Not available | Not available | Not available | Not available | Not available | No | - Three studies used this version to assess PTG in cancer survivors: ELCCA [27], VICAN [28], and EPICURE [29] - One study used this version to assess PTG in cancer patients and health care workers during Covid-19 pandemic (PAPESCO-19) [30] - One study used this version to assess PTG in renal failure patients waiting for first kidney transplantation (PreKitQol) [31] |
Version 3:Translation of Cadell et al. | See Cadell et al. [12] Sample: N = 10 Bereaved caregivers (Canada) + N = 37 Parents caring for a child with a life-limiting illness (Canada) | RO: 0.85 NP: 0.83 SC: 0.86 AL: 0.64 PS: 0.34 (0.77 when omitting item 12a) Total PTGI (21 items): 0.87 | Within each domain, all items were significantly correlated, except for item 12a | Five unidimensional CFAs (one per domain) + One CFA on the five mean scores to the domains Remark: No multidimensional CFA combining the five domains and the associated items was performed | All standardized factor loadings from the five CFAs were above 0.5 All standardized factor loadings from the CFA performed on the mean scores were above 0.5 (except for AL score) | Not available | Dimensionality was explored and reported in terms of discriminant validity. It was assessed for each pair of domains by comparing the chi-square statistic of two CFAs: 1) A CFA where the correlation between the two factors is constrained to be equal to 1 2) A CFA where the correlation is freely estimated | - One study used this version to assess PTG after a hematopoietic stem-cell transplantation [32] - One study used this version to assess PTG in survivors of a diffuse large B-cell lymphoma [33] |
