Adaptation and preliminary evaluation of the psychometric properties of the Polish version of the gratitude/awe questionnaire (GrAw-7)

Kurzfassung/Abstract

We conducted three studies to validate the Polish version of the GrAw-7. Our objectives are as follows: first, to explore the dimensional structure of the scale and to determine the internal consistency (study 1: N = 635); second, to verify the stability of the GraW-7 (study 2: N = 27); and third, to determine the validity of the GrAw-7 (study 3: N = 385). To explore the dimensional structure of the scale, we tested a one-factor model proposed by Büssing (2018). To determine the validity of the GrAw-7, we analysed correlations among Awe/Gratitude and gratitude as an affective trait, resilience, health behaviours, transcendence and openness to spirituality. Based upon the presented data, it can be concluded that the Polish version of GrAw-7 has good psychometric qualities that are similar to those of the original version. The CFA results confirmed that the univariate solution is well adjusted to the data. The internal compatibility assessment is good. The absolute stability (test-retest) was estimated to be high. Based upon the results obtained, the questionnaire was demonstrated to be convergently valid as the overall GrAw-7 scores correlated positively with dispositional gratitude, resilience, transcendence proper, spiritual openness, and health-related behaviours.
