Measures of beliefs and attitudes towards food need to be valid, and easy to use and interpret. The present study aimed to establish the validity and reliability of a short-form of the Food-Life Questionnaire (FLQ). Participants (247 females; 118 males), recruited in South Australia, completed a questionnaire in 2012 incorporating the original FLQ, a revised short form (FLQ-SF), and measures of food choice and consumption. Validity (construct, criterion-related, and incremental) and reliability (internal consistency and short-form) were assessed. Factor analysis established that short-form items loaded onto five factors consistent with the original FLQ and explained 60% of variance. Moderate correlations were observed between the FLQ-SF and a measure of food choices (r = .32–.64), and the FLQ-SF predicted unhealthy food consumption over and above the full FLQ demonstrating criterion-related and incremental validity respectively. The final FLQ-SF included 21 items and had a Cronbach’s alpha of .75. Short-form reliability was established with correlations between corresponding subscales of the FLQ and FLQ-SF ranging from r = .64–.84. Overall, the FLQ-SF is brief, psychometrically robust, and easy to administer. It should be considered an important tool in research informing public policies and programs that aim to improve food choices.
