This is the stage where people believe they have the ability to change their behavior and are actively involved in taking steps to change their bad behavior by using a variety of different techniques. This is the shortest of all the stages. The amount of time people spend in action varies. It generally lasts about 6 months, but it can literally be as short as one hour! This is a stage when people most depend on their own willpower. They are making overt efforts to quit or change the behavior and are at greatest risk for relapse.
Mentally, they review their commitment to themselves and develop plans to deal with both personal and external pressures that may lead to slips. They may use short-term rewards to sustain their motivation, and analyze their behavior change efforts in a way that enhances their self-confidence. People in this stage also tend to be open to receiving help and are also likely to seek support from others which is a a very important element. Hopefully, if the are successful in this stage they move to maintenance. More on that tomorrow!
