Identification of behavior change techniques applied in interventions to improve cooking skills and food skills among adults

摘要

BackgroundCooking and food skills interventions have grown in popularity; however, there is a lack oftransparency as to how these interventions were designed, highlighting a need to identify andunderstand the mechanisms of behavior change so that effective components may be introduced infuture work. This study critiques cooking and food skills interventions in relation to their design, behaviorchange techniques (BCTs), theoretical underpinnings, and outcomes.MethodsA 40-item CALO-RE taxonomy was used to examine the components of 59 cooking and foodskills interventions identified by two systematic reviews. Studies were coded by three independent coders.ResultsThe three most frequently occurring BCTs identified were #1 Provide information on consequencesof behavior in general; #21 Provide instruction on how to perform the behavior; and #26 Prompt Practice.Fifty-six interventions reported positive short-term outcomes. Only 14 interventions reported long-termoutcomes containing BCTs relating to information provision.ConclusionThis study reviewed cooking and food skills interventions highlighting the most commonlyused BCTs, and those associated with long-term positive outcomes for cooking skills and diet. This studyindicates the potential for using the BCT CALO-RE taxonomy to inform the design, planning, delivery andevaluation of future interventions.
