Abstract: | Abstract In a sample of 1,166 Catholic high school students (age = 13–18 years), the author used confirmatory factor analysis to validate a 30-item instrument that assesses 6 dimensions of attitude to Christianity (viz., attitude to prayer, attitude to God, attitude to Jesus, attitude to the Bible, attitude to Christian practice, attitude to social justice). Goodness-of-fit indices for the proposed measurement model revealed that the model fitted the data very well, thus confirming the instrument's structure. A correlation analysis revealed associations between religious behavior and attitude to Christianity. |
