越来越多的证据表明，水果和蔬菜的摄入(FVI)对重大疾病具有保护作用。尽管有这种保护作用和肥胖大流行的背景，但西方国家的人们通常每天吃的水果和蔬菜远远不到五份。为了提高干预措施的效率，应针对FVI最重要的决定因素或调解人进行调整。其目的是系统地回顾基于社会认知理论的FVI研究，并确定其主要的心理社会决定因素。系统地利用当前内容(2007-2009年)和Medline、Embase、SqucINFO、ProQuest和论文以及Cinhal(1980-2009)检索已发表的论文。其他研究是通过在书目中手动搜索来确定的。搜索词包括水果、蔬菜、行为、意图以及具体理论的名称。只有通过社会认知理论预测一般人群的FVI或食用水果和蔬菜的意愿的研究才被包括在内。信息的独立提取是由两个人使用预定义的数据字段进行的，包括研究质量标准。总共确定并纳入了23项研究，其中15项只研究FVI的决定因素，7项研究FVI和意向的决定因素，1项只研究意向的决定因素。所有的合并分析都基于随机效应模型。FVI预测的随机效应R2为0.23，意图预测的随机效应R2为0.34。最常使用的是多元理论框架和计划行为理论(TPB)。一些方法学调节因素影响了FVI预测的有效性。预测行为最一致的变量是习惯、动机和目标，对能力、知识和品味的信念；解释意图的变量是对能力的信念、对后果的信念和感知的社会影响。我们的结果表明，TPB和社会认知理论(SCT)是预测行为的较好的社会认知理论，TPB是解释意图的较好的社会认知理论。然而，预测的有效性受到方法学因素的负面影响，例如研究设计以及心理社会和行为措施的质量。
Accumulating evidence suggests that fruit and vegetable intake (FVI) plays a protective role against major diseases. Despite this protective role and the obesity pandemic context, populations in Western countries usually eat far less than five servings of fruits and vegetables per day. In order to increase the efficiency of interventions, they should be tailored to the most important determinants or mediators of FVI. The objective was to systematically review social cognitive theory-based studies of FVI and to identify its main psychosocial determinants. Published papers were systematically sought using Current Contents (2007-2009) and Medline, Embase, PsycINFO, Proquest and Thesis, as well as Cinhal (1980-2009). Additional studies were identified by a manual search in the bibliographies. Search terms included fruit, vegetable, behaviour, intention, as well as names of specific theories. Only studies predicting FVI or intention to eat fruits and vegetables in the general population and using a social cognitive theory were included. Independent extraction of information was carried out by two persons using predefined data fields, including study quality criteria. A total of 23 studies were identified and included, 15 studying only the determinants of FVI, seven studying the determinants of FVI and intention and one studying only the determinants of intention. All pooled analyses were based on random-effects models. The random-effect R2 observed for the prediction of FVI was 0.23 and it was 0.34 for the prediction of intention. Multicomponent theoretical frameworks and the theory of planned behaviour (TPB) were most often used. A number of methodological moderators influenced the efficacy of prediction of FVI. The most consistent variables predicting behaviour were habit, motivation and goals, beliefs about capabilities, knowledge and taste; those explaining intention were beliefs about capabilities, beliefs about consequences and perceived social influences. Our results suggest that the TPB and social cognitive theory (SCT) are the preferable social cognitive theories to predict behaviour and TPB to explain intention. Efficacy of prediction was nonetheless negatively affected by methodological factors such as the study design and the quality of psychosocial and behavioural measures.
