The big five personality traits are the best accepted and most commonly used model of personality in academic psychology. The big five come from the statistical study of responses to personality items. Using a technique called factor analysis researchers can look at the responses of people to hundreds of personality items and ask the question "what is the best was to summarize an individual?". This has been done with many samples from all over the world and the general result is that, while there seem to be unlimited personality variables, five stand out from the pack in terms of explaining a lot of a persons answers to questions about their personality: extraversion, neuroticism, agreeableness, conscientiousness and openness to experience. There are many different measures of the big five personality traits. This test uses the Big-Five Factor Markers from the International Personality Item Pool, developed by Goldberg (1992).
Self-confidence is an attitude in which individuals have positive, but at the same time realistic, views about themselves and their situation. Such an attitude means that self-confident people are able to place trust in their own abilities and decisions. It also means they are able, to a great extent and within reason, to take control of their own lives and stand up for their rights and aspirations in today’s sometimes intimidating world.
