The Development and Validation Of The Islamic Gratitude Scale (IGS-10)

There were not many adequate instruments to measure gratitude for the Indonesian people, especially the Muslim community. The purpose of this study is to develop the Islamic Gratitude Scale (IGS-10) by conducted an adequate set of tests. A total of 1218 respondents from students and workers participated on this study. This study found that the Islamic Gratitude Scale (IGS-10) has a good reliability (α= 0.863), good content validity and good factorial validity. The exploratory factor analysis found that IGS-10 has two factors, extrinsic gratitude (α= 0.845) and intrinsic gratitude (α= 0.761). Several sets of correlation tests found that IGS-10 has a good convergent validity, IGS-10 correlates with the Gratitude Questionerre (GQ-6), Gratitude Resentment and Appreciation Scale - Short Form (GRAT-SF), and gratitude toward God. Furthermore, IGS-10 correlated with Subjective Happiness Scale (SHS), Positive Affect and Negative Affect Schedule (PANAS), Multidimensional Body Self Relations Questionnaire - Appearance Scale (MBSRQ - US), and subjective well-being. This finding indicated that IGS-10 has a good cirterion-related validity. But unfortunately, IGS-10 did not correlate with Adolescents’ Self-concept Short Scale (ASCSS), optimism scale (LOT-R) and The Satisfaction with Life Scale (SWLS). IGS-10 was associated with Social Desirability Scale (SDS) with low correlation. To develop this scale the next process that can be done is norming, so that the IGS-10 will become a scale that can be used widely and more convincingly.
