The Inventario de Comportamiento de Estudio (ICE), a Spanish translation of the Study Behavior Inventory (SBI) was developed and tested using a group of 594 undergraduate students from randomly selected classes at a private comprehensive university in Mexico. Both instruments were designed to assess the study behaviors of students in institutions of higher education. A team of bilingual specialists at the university developed the ICE with the intention of producing a translation that was generic enough to be understood across Spanish speaking nations and cultures. A pilot test with 30 students resulted in a Cronbach's alpha value of 0.84 and agreement scores on items ranging from 63.7% to 100% on administrations that were separated by 7 days. Factor analysis of the scores of the sample of 594 revealed 4 factors that accounted for 89% of the total variance of the scores. Three were virtually identical to those of the SBI, but the fourth consisted of only two items that dealt with student preference for studying alone or with other students. Those two items did not load on any SBI factors. There were no significant gender differences in the mean scores, and Cronbach's alpha values ranged from 0.76 to 0.85 for the total instrument and first four factors. Correlations between total ICE and the first three factor scores ranged from 0.65 to 0.73. Finally, the correlations between the ICE scores and students' cumulative grade point averages ranged from 0.66 to 0.72. The authors note the limitations of the sample and describe the need for a broader validation sample which is representative of Spanish speaking university students across nations and cultures. The ICE is presented in an appendix. (Contains 2 tables and 20 references.) (Author/SLD)
