ABSTRACT
This chapter examines a number of the major theories on behaviour change. A theory is an organised, heuristic, coherent and systematic articulation of a set of statements related to significant questions that are communicated in a meaningful whole for the purpose of providing a generalisable form of understanding. Six major macro-theoretical and mid-range theoretical approaches are discussed:
passive;
behavioural learning;
communication;
cognitive;
self-regulation; and
stage or transtheoretical perspectives.
