What is CEOS Theory?
CEOS Theory is a model for understanding how and why some behaviour change is difficult to maintain, for example giving up smoking and other addictions, sticking to a diet, keeping going with New Year’s resolutions like new fitness regimes, working differently etc. CEOS Theory focusses on the interaction between conscious and non-conscious influences on behaviour and is aimed at explaining and exploring the limits of rational choice and behaviour. CEOS is an acronym for Context, Executive, and Operational Systems.
CEOS Theory was developed from a mixture of Social Ecological Theory (Borland, Owen, Hill, & Chapman, 1994; Sallis, Owen, & Fisher, 2008); and Expectancy-Value Theory (Ajzen, 1991; Becker & Murphy, 1988; Rosenstock, Strecher, & Becker, 1988) by Ron Borland (Borland, 2016).
