Develop a questionnaire to measure students' knowledge, attitude, behavior, self-efficacy, and environmental factors related to the use of canned foods.


The Knowledge–Attitude–Behavior Model, Social Cognitive Theory, and Canned Foods Alliance survey were used as frameworks for questionnaire development. Cognitive interviews were conducted with college students (n = 8). Nutrition and survey experts assessed content validity. Reliability was measured via Cronbach α and 2 rounds (1, n = 81; 2, n = 65) of test-retest statistics. Means and frequencies were used.


The 65-item questionnaire had a test-retest reliability of .69. Cronbach α scores were .87 for knowledge (9 items), .86 for attitude (30 items), .80 for self-efficacy (12 items), .68 for canned foods use (8 items), and .30 for environment (6 items).

Conclusions and Implications:

A reliable questionnaire was developed to measure perceptions and use of canned foods. Nutrition educators may find this questionnaire useful to evaluate pretest–posttest changes from canned foods–based interventions among college students.
