On the efficacy of volitional personality change in young adulthood: Convergent evidence using a longitudinal personal goal paradigm

The frequency, effectiveness, and impact of personality change goal (PCG) pursuit was explored using a longitudinal goal-setting paradigm within two multi-wave prospective longitudinal studies employing both a university student (study 1; n = 1468) and community adult (study 2; n = 248) sample. Self-determination theory (SDT) was incorporated to explore the extent to which PCGs reflect autonomous processes. Five major findings were revealed in study 1: (1) 20% of participants generated a PCG as one of their three yearly goals; (2) participants reported more progress on their PCGs than on other goals; (3) PCGs were more autonomous relative to other personal goals; (4) Autonomous motivation for goal pursuit was more strongly associated with PCG progress, relative to other goals; and (5) PCG progress resulted in improved psychological well-being over time. Study 2 replicated the motivational findings of study 1 within a community adult sample, and found evidence supporting the validity of the proposed longitidunal goal-setting paradigm. The present studies contribute to current PCG literature by using an alternate goal-assessment method that distinguishes desires to change from meaningful goal intentions and integrated SDT to enhance our understanding of volitional personality change.
