This study examined the relative effects of agency beliefs for strategy, perceived cost, and perceived utility on the use of cognitive strategies at the strategy-specific level. A self-report questionnaire survey was administered to 180 undergraduates. The results of multiple regression analysis indicated that agency beliefs for strategy had the strongest positive effect on the use of all cognitive strategies (writing-repetition strategy, elaboration strategy, writing-organizational strategy, and organizational strategy); perceived cost did not have an effect; and perceived utility had a weak positive effect except for organizational strategy.
