Guilt and Shame Proneness Scale (GASP) Adaptation and Psychometric Properties in Spanish Population

Aims:To develop a Spanish version of the Guilt and Shame Proneness Scale (GASP) and evaluate its psychometric properties among a population in Spain. Methods: A Spanish version of the Guilt and Shame Proneness Scale (GASP) was developed by a Spanish and English speakers through translation and back-translation. The translated GASP was administered to a sample of Spanish general population. The validity and reliability of the scale were tested using standard statistical methods. Results: The translated version of the GASP scale was found to have outstanding domain coherence and language clarity. The tested scales have adequate reliability (>0.55). It is clear evidence of reliability given that the GASP is a scenario-based measure with only four items in each subscale. Confirmatory factor analysis confirmed the four-factor solution by yielding adequate results. Conclusions: This study presents the first validation of the GASP questionnaire with Spanish general population. GASP instrument was found to have satisfactory psychometric properties, resulting in a new moral and social research tool.
