Abstract

Optimism is one human characteristic which for many years has been of central interest to psychology. This variable is usually treated as a one-dimensional human trait. This text presents a different view of optimism. It includes a discussion of a multidimensional questionnaire for the measurement of optimism: the Optimistic Attitude Questionnaire. The OAQ measures four dimensions of optimism: achievement orientation, incaution, positive thinking, and openness. The results of a k-means clustering procedure that was conducted on a group of 766 adults are presented as well. The results of the analysis reveal five different profiles: global optimists, pessimists, cautious optimists, moderate optimists, and risk-takers. The obtained profiles are significantly different from each other - for example, with respect to the age of the participants and their evaluations of life satisfaction.
