"This study investigates the possibility that (unknown) institutional differences might affect the validity of a forced-choice study activity questionnaire (SAQ) validated at a state college and then applied in a private university." Ss were 189 sophomore, junior, and senior students of finance and commerce taking an introductory psychology course. The 3 variables were the SAQ, SAT-V (Scholastic Aptitude Test--Verbal) and GAP (grade point average). The correlations between SAQ and SAT-V were .03, SAQ and GPA .48. Combined SAQ and SAT-V multiple correlation with GPA .62. "Thus SAQ is significantly valid and, together with the scholastic aptitude test, gives significant multiple prediction of grade-point average in both situations."
