Low-educated adults participate less in adult education than higher-educated adults. In this study, we analyze psychosocial barriers to learning while acknowledging that barriers for low-educated adults may be different from those of medium- and high-educated adults. An extended version of the Theory of Planned Behavior is used to study training intention. We add prior Learning Experiences as predictor to the model. A total of 563 adults filled in the questionnaire. Higher-educated adults show more Perceived Behavioral Control, Perceived Social Norms, and more positive Attitudes towards lifelong learning. Logistic regression demonstrated that Perceived Behavioral Control, Perceived Social Norms and Attitudes are related to training intention, but prior Learning Experiences are not. Mediation analyses showed that the relationship between Perceived Behavioral Control and Intention is mediated through Learning Experiences. The findings suggest that psychosocial barriers need to be taken into account when considering how to reach non-participating adults.
