states that there are stages of change which a person needs to go through in order to change a behaviour
stages of change
precontemplation
contemplation
preparation
action
maintenance
relapse
precontemplation
being in denial or being unaware of the problem behaviour
contemplation
weighing up the pros and cons of change
preparation
start to collect information about changing behaviours
action
people may take measurements to establish their successes
maintenance
the actions taken may become 'habitual' and temptations continue to be avoided
relapse
this can happen at anystage, and relapse can be disappointing but it can help the person to overcome their problems
eval
-the theory only focuses on the individual in relation to behaviour change. It doesnt recognise the role of external factors
eval
-there is no set criteria to know what stage a person is in, so can be unreliable
eval
-the model assumes that an individual is logical and coherent in their decision making
AVEYARD et al
found that the effectiveness of TTM based interventions was not explained by the fact that these matched the stage in the TTM to the type of intervention given
