## Study Description ## The Child Personality and Behavioral Outcomes Study in Toronto, ON (CPBS-T) was a longitudinal study including an intake (INT) sample and three follow-ups (FU1-FU3). The primary aims of this study were to investigate the structure, measurement, and development of personality characteristics between middle childhood and adolescence, as well as associations between personality, psychopathology, and other cognitive and non-cognitive psychological variables. These data were collected over approximately six years at the University of Toronto. INT was collected from 2007-2009, FU1 from 2008-2010, FU2 from 2009-2011, and FU3 from 2010-2013. INT and FU2 data were collected in-lab, while FU1 and FU3 were collected via mailed questionnaires. While this project was a longitudinal study, new participants were introduced at FU2 to compensate for attrition. The sample sizes and child ages for each of the waves are as follows: - INT: N = 346 (50.6% female, M(age) = 9.97, SD = 0.83) - FU1: N = 239 (52.1% female, M(age) = 11.11, SD = 0.89) - FU2: N = 363 (52.9% female, M(age) = 12.11, SD = 0.81) - FU3: N = 350 (51.1% female, M(age) = 13.11, SD = 0.83) Participants for this study were recruited from the Toronto, ON area using directory information from local school districts and flyers advertising the study in the community. Inclusion criteria for this study included child and caregiver fluency in English. Exclusion criteria for the child included a lifetime history of psychotic disorders, intellectual disability, or neurodevelopmental disorders.
