a All items used a 7-point response scale, with 1 = "Absolutely Disagree" and 7 = "Absolutely Agree." b Product-moment correlation corrected by excluding the item score from the total score. All correlations are statistically significant (p < .0005). c Product-moment correlation using IMAQ scale score as the criteria score. All correlations are statistically significant (p < .0005). d Some statistics calculated with student sample size < 272 because of missing data. e Item responses were reverse scored so a higher value indicated greater endorsement.
