Abstract
While it is one of the best preventive healthcare practices, individuals engage too
little in physical activity. Physical activity is related to a longer life span, can delay
the onset of chronic conditions and has positive financial consequences. This
research examined the effect of an intervention combining several behaviour
change techniques: implementation intentions, public commitment, and self persuasion, on self-reported physical activity. The sample (N=14, Mage=27.64 years,
SD=5.11) took part in a short-term longitudinal study with a three-wave mixed
design. Their physical activity level was assessed with the International Physical
Activity Questionnaire. A Repeated Measures ANOVA was conducted and
indicated no significant changes in the level of physical activity between the pre measure, post-measure, and follow-up in the different conditions. By conducting an
exploratory analysis, it appeared that self-persuasion as well as providing ten pro
physical activity arguments could increase physical activity intention more than
their level of physical activity in the past seven days. These results have important
implications for behavioural change in the area of physical activity.
