Abstract (Swedish)
The Theory of Planned Behavior (TPB) is a widely applied theory to assess the impact of
attitudes, subjective norms, perceived behavioral control and intention on behavior. The aim of this study is to analyze the impact of intention on actual electricity consumption as well as the relative impact of the underlying factors on intention to save electricity. This separates the study from most previous studies as these tend to use self-assessment measurements of electricity consumption. The study consists of a five week, longitudinal, quantitative data collection. This data was then analyzed using both longitudinal and non-longitudinal structural equation modeling. Analysis found practically nonexistent relationships between intentions to... (More)

This separates the study from most previous studies as these tend to use self-assessment measurements of electricity consumption. The study consists of a five week, longitudinal, quantitative data collection. This data was then analyzed using both longitudinal and non-longitudinal structural equation modeling. Analysis found practically nonexistent relationships between intentions to save electricity and actual electricity consumed across the five weeks in the longitudinal model. Perceived behavioral control was found to be the most influential predictor of intention. The
relative impact of attitudes started out non-significantly in week one but increased over time, and the relative impact of subjective norm decreased over time to end up as non-significant. This is compared with previous findings that generally has found attitudes to be the strongest predictor of intention to save electricity, followed by perceived behavioral control and subjective norms.
