Theory constructs and annotations

• Behaviour change Occurrence of a behaviour that is different, or enacted in a different way, from one that would have occurred had an intervention not been applied [ BCIO:050209 (Individual human behaviour change) 45 32 66 72 6 ]
• Self-esteem The degree to which the qualities and characteristics contained in one's self-concept are perceived to be positive [ BCIO:006035 (Evaluation of self) 45 46 20 ]
• Self-efficacy The belief one has that one can accomplish a specified task [ BCIO:050898 (Self-efficacy belief) 45 ]
• Locus of control The extent to which one attributes valued outcomes or reinforcement to either internal or external circumstances. [ BCIO:050588 (Belief about control over valued outcomes) 45 ]
• Motivation The desire to change, defined by a person's beliefs about importance, beliefs about personal risk, and beliefs about the efficacy of change [ BCIO:050716 (motivational disposition to change behaviour) 45 25 6 ]
• Resistance An opposing force of motivation that acts to defy or withstand change; characterized by one's capability to change, locus of control and fixed impediments to change [ BCIO:050715 (motivational disposition not to change behaviour) 45 , BCIO:050698 (Low opportunity to enact a behaviour) 45 , BCIO:050695 (Low capability to enact a behaviour) 45 25 47 32 66 ]
• Beliefs about importance Perceptions of how important the health condition to be avoided is [ BCIO:050597 (belief about severity of health condition) 45 27 14 32 ]
• Beliefs about personal risk Perceptions of one's personal risk of experiencing the health condition [ BCIO:0050003 (Belief about threat) 45 27 24 ]
• Beliefs about the efficacy of change Perceptions of whether change will lead to the desired health outcome [ BCIO:050219 (Belief about health consequences of behaviour) 45 25 ]
• Capacity The ability or capacity to make a change in the behaviour [ BCIO:050215 (Behavioural capability) 45 31 32 30 ]
• Fixed impediments to change Barriers that cannot be changed, that make behaviour change difficult [ BCIO:050577 (Behavioural barrier) 45 29 39 35 6 4 ]
• Precontemplative with no prior behaviour change attempts A category of people who perceive the difficulties of behaviour change to outweigh the benefits, who are unwilling to (or unaware of the possibility of) change, and who have not previously made any behaviour change attempts [ BCIO:050715 (motivational disposition not to change behaviour) 45 25 ]
• Clinical scenarios Discrete categories that people can be classified into that can be used to direct the appropriate form of behavioural counselling strategies
• Contemplative or preparative with no prior behaviour change attempts A category of people who are aware of a need to change or who are making preparations to change, but who are highly resistant to change and have not made any previous behaviour change attempts [ BCIO:050697 (low motivational disposition to change behaviour) 45 17 56 ]
• Behaviour modification or maintenance of behaviour change A category of people for whom motivation to change behaviour outweighs resistance to change and who have made a change in their behaviour
• Lapse A category of people who have previously changed their behaviour, but who are currently experiencing a lapse such that they have reverted to the behaviour pattern that preceded the change [ BCIO:050482 (personal history of behavioural lapse) 45 ]
• Precontemplative or contemplative with prior behaviour change attempts A category of people who either a) perceive the difficulty of change to outweigh the benefits of change, are unwilling to change, to whom alternative behaviours are unfamiliar, and who are unaware of the possibility of change or b) are aware of a need to change their behaviour, and who have made previous attempts to change the behaviour that were either unsuccessful or were terminated by relapse [ BCIO:050697 (low motivational disposition to change behaviour) 45 17 56 ]
