Abstract
BackgroundTheories of behavior change are essential in the design of effective behaviour change strategies. No studies have assessed the effectiveness of interventions based on psychological theories to reduce sugar intake related to dental caries. The study assessed the effect of interventions based on Social Congition Models (SCMs) on sugar intake in adults, when compared with educational interventions or no intervention.MethodsA range of papers were considered: Systematic review Systematic Reviews with or without Meta Analyses; Randomised Controlled Trials; Controlled Clinical Trials and Before and after studies, of interventions based on Social Cognition Models aimed at dietary intake of sugar in adults. The Cochrane database including: Oral Health Group’s Trials Register (2015), MEDLINE (from 1966 to September 2015), EMBASE (from 1980 to September 2015), PsycINFO (from 1966 to September 2015) were searched.ResultsNo article met the full eligibility criteria for the current systematic review so no articles were included.ConclusionThere is a need for more clinical trials to assess the effectiveness of interventions based on psychological theory in reducing dietary sugar intake among adults.Systematic Review Protocol RegistrationPROSPERO: CRD42015026357.

Theories of behavior change are essential in the design of effective behaviour change strategies
Social Cognition Models (SCMs) are a subgroup of psychological theories, which are based on the assumption that the individuals’ attitudes and beliefs towards a behaviour are strongly predictive of the likelihood of them engaging in that behaviour [8]
Related to general health in highly selected patient groups. Stacey and his colleagues [9] conducted a systematic review and meta-analysis to assess the effectiveness of physical activity and dietary change interventions based on Social Cognitive Theory among individuals who had survived a cancer diagnosis
Summary
Theories of behavior change are essential in the design of effective behaviour change strategies. Theories of behavior change [1–4] are essential in the design of effective behaviour change strategies Such theories [5, 6] can be helpful in improving our understanding of how behaviour change might lead to a healthy lifestyle. Social Cognition Models (SCMs) are a subgroup of psychological theories, which are based on the assumption that the individuals’ attitudes and beliefs towards a behaviour are strongly predictive of the likelihood of them engaging in that behaviour [8]. Interventions based on such models have been shown to improve dietary behaviours related to general health in highly selected patient groups. The authors, concluded that interventions based on psychological theories are effective in changing behaviour
