The aim of this paper is to present the results associated with the construction of a new scale to measure openness to experience on the five factorial model (FFM).  Openness to experience is one of the big five personality dimensions. It is related to features such as aesthetic sensitivity, appreciation of beauty and willingness to consider alternative ideas and values. The majority of the studies have found six dimensions to openness: fantasy, ideas, values, aesthetics, feelings, and actions. People with high scores on openness are characterized by consider new values, new ideas, the also actively pursue different activities that may help them to experience different feelings.

Two studies have been conducted with a total sample of 1924 people. The participants aged between 17 and 62 years (M = 22.1, SD = 5.7). They answered a sociodemographic questionnaire, the instrument developed to measure openness to experience and Bateria Fatorial de Personalidade (Nunes, Hutz & Nunes, 2009). In the first study exploratory analyzes were performed using a portion of the sample. In the second study, confirmatory analyses with other participants were conducted.

In the first study were found a factor structure of six factors with alpha coefficients ranging between .80 and .96. The factors describe characteristics related to fantasy, ideas, values, aesthetics, feelings, and actions. This result is in according to the McCrae and Costa (1992) original studies. In the second study the structure has been confirmed. The adjustment values found in the second study are similar to those in international studies. The results suggest evidence of validity and adequate psychometric properties of the instrument.
