Self-report measures can overestimate as well as underestimate how much people actually do.3 Individuals’ attitudes and beliefs, coupled with the beliefs of people they interact with, influence intention to exercise,4 as well as actual levels of exercise adherence.

Replies to questions asked about adherence may reflect what the person feels is the desired response rather than a true appraisal of their behaviour, giving a falsely positive estimate of adherence.5 6 This may be one reason why unsupervised home-based exercise programmes are deemed ineffective, when in reality ‘an insufficient regimen effect’ has occurred.7 For the purposes of this review adherence is defined as the degree behaviour corresponds with an agreed on recommendation.
