Abstract
This study verifies the psychometric properties of the Santa Clara Strength of Religious Faith Questionnaire (SCSORFQ). This measure consists of 10 items regarding strength of religious faith, regardless of religious denomination or affiliation. Participants were 177 students from Chile and 393 students from Poland. The SCSORFQ method is a reliable measure with good internal consistency evaluated by the α-Cronbach coefficient. Factor analysis statistically confirmed the unidimensional structure of the SCSORFQ. The strength of religious faith in both student groups was moderate to strong correlated with public or private aspects of religiousness and strong correlated with spiritual experiences. It was weakly correlated with the cognitive indicator of well-being as satisfaction with life as well as with existential variables like hope and meaning of life. The results confirm that the SCSORFQ is psychometrically sound and is therefore recommended for use by researchers studying the construct of religiousness.
