Abstract

The Generalized Self-Efficacy Scale (GSES) is a widely used scale to assess an individual’s capacity to effectively deal with challenging and stressful situations. Self-efficacy is a construct that is widely addressed in the field of health psychology and often associated with psychotherapy. The scale was culturally adapted to Sinhala language in 2015. The objective of the present study was to investigate psychometric properties of the Sinhala generalized self-efficacy scale (S-GSES) and to statistically validate it for future use. The study used 142 randomly selected individuals as its sample. The S-GSES demonstrated an outstanding internal consistency reliability of .860. Further, an item total correlation was conducted to further understand the reliability of each item. Internal structure was explored and unidimensionality was demonstrated through principal component analysis and principal axis factoring. Criterion validity was demonstrated through a correlation between S-GSES and Teachers Sense of Efficacy Scale (TSES), and the results indicated a strong correlation of r = .574. Further, a Graded Response Model was performed to investigate the S-GSES under Item Response Theory. The results indicated good psychometric properties confirming the scale’s ability to be used in future to assess self-efficacy of people in Sri Lanka.
