Over the same time, there was a perceptual stasis in hopelessness for JPOs randomized to deliver probation services as usual, and there was degradation in their previously positive perception toward tangible incentives. The study advances thinking regarding tools that JPOs can use for working with youth and families and the role that task-shifting can play in both increasing access to evidence-based treatments and improving attitudinal outcomes of JPOs.Prior research suggests that personality traits change during substance use disorder (SUD) treatment. However, the extent to which changes in traits during SUD treatment are associated with subsequent improvements in treatment outcomes remains untested. Among U.S. military veterans (n = 200) enrolled in SUD residential treatment, we examined whether changes in the personality factors of positive emotionality (PEM), negative emotionality (NEM), and constraint (CON) during treatment were associated with subsequent changes in abstinence self-efficacy and SUD symptoms. We analyzed data at treatment entry, discharge, and 12-months post-discharge via univariate and bivariate latent change score models. During treatment, PEM, CON, and abstinence self-efficacy increased, while NEM decreased, on average. Changes in NEM and CON were largely sustained, whereas PEM and abstinence self-efficacy significantly decreased post-treatment. SUD symptoms decreased from pre- to post-treatment. In bivariate models, higher levels of NEM at baseline were associated with less improvement in both abstinence self-efficacy during treatment and SUD symptoms pre- to post-treatment. Higher levels of CON at baseline were associated with greater i
