Development and evidence of validity of an extraversion measure from an ideal point process perspective

Although extraversion is generally seen as a positive trait, recent research has suggested that seemingly positive traits may have an inflection point, at which they result in negative outcomes. To maximize accuracy when examining possible curvilinear relationships, research suggests the utilization of an ideal point approach should be used both in scale development and in scoring. This study describes the development of the first ideal point scale of extraversion, which is tested for curvilinear relationships with common correlates at the general factor level and the facet level. Notably, the ideal point approach and the traditional dominance point approach are compared in regards to their capabilities of identifying curvilinear relationships. Implications for facet level examination of curvilinear relationships are discussed.
