Amongst the plethora of behaviour change theories (with some reviews highlighting up to 100 models REF), an uneven frequency of theory use exists. Early social cognition models dominate the literature \citep*{Davis_2014}; models which collectively take a continuum approach to behaviour change and examine the predictors and precursors of health behaviours \citep*{Bandura_2004} (Michie et al., 2005). Table ?? provides an overview of the most prevailing models utilised to explain health behaviours in a variety of populations (for an extensive review of behaviour change theories, see ??). Many theories of behaviour change draw upon similar, overlapping constructs \citep*{Bandura_2004} (Michie et al., 2005). In fact, a systematic review of ?82? behaviour change theories identified five overarching, interconnected themes central to behaviour maintenance \citep*{Kwasnicka_2016} . Themes reflected the differential nature and role of motives, self-regulation, resources (psychological and physical), habits, and environmental and social influences from initiation to maintenance. Particularly, theoretical explanations propose that behaviour will be maintained if a person has at least one maintenance motive, i.e. if the behaviour is pleasurable, if the behaviour is congruent with a persons's identity, beliefs and values, and if the person is satisfied with the behavioural outcome. Research consistently indicates XXX. Secondly, behaviour is likely to be maintained if the person successfully monitors and self-regulates the new behaviour and is equipped with effective strategies to overcome barriers. Thirdly, it is considered that behaviour maintenance will be successful if an individuals psychological and physical resources are plentiful. Behaviours which have become habitual and are supported by automatic responses to cues are also likely to be sustained.
Lastly, a supportive environment and social support are important for behaviour change maintenance as people tend to maintain behaviour which is in line with relevant social changes
