Desires to increase in extraversion and conscientiousness as well as to decrease in neuroticism are the three most prevalent personality change goals. This study describes characteristics of people who wanted to change one of these personality traits (total N = 1196) with the help of a digital personality change intervention. The extent to which characteristics predicted the selection of one change goal over the other two was explored using machine learning. Individuals desired to change traits with lower (in case of desires to increase) or higher (in case of desires to decrease) self- and observer-reports and with greater self-other discrepancies. This identification of characteristics of people who desired to change certain personality traits informs future interventions.
