The beliefs that people hold about themselves, their life and future are important and mutually related constituents of psychological functioning and well-being. In this paper, we investigated the relationship between positive orientation and generalized self-efficacy. The sample consisted of 672 participants aged 15-72 years (274 males). The results confirmed the first hypothesis that positive orientation and generalized self-efficacy constitute two distinct but correlated constructs. The results were confirmed across the three age groups and, contrary to the second hypothesis, age was not confirmed as a moderator of the relationship between positive orientation and self-efficacy.
