    Decisional Informatics for Psychosocial Rehabilitation: A Feasibility Pilot on Tailored and Fluid Treatment Algorithms for Serious Mental Illness
    (Wolters Kluwer, 2017-11) Choi, Jimmy; Lysaker, Paul H.; Bell, Morris D.; Dixon, Lisa; Margolies, Paul; Gold, Matthew; Golden-Roose, Elizabeth; Thime, Warren; Haber, Lawrence C.; Dewberry, Michael J.; Stevens, Michael; Pearlson, Godfrey D.; Fiszdon, Joanna M.; Medicine, School of Medicine
    This study introduces a computerized clinical decision-support tool, the Fluid Outpatient Rehabilitation Treatment (FORT), that incorporates individual and ever-evolving patient needs to guide clinicians in developing and updating treatment decisions in real-time. In this proof-of-concept feasibility pilot, FORT was compared against traditional treatment planning using similar behavioral therapies in 52 adults with severe mental illness attending community-based day treatment. At posttreatment and follow-up, group differences and moderate-to-large effect sizes favoring FORT were detected in social function, work readiness, self-esteem, working memory, processing speed, and mental flexibility. Of participants who identified obtaining a General Education Diploma as their goal, 73% in FORT passed the examination compared with 18% in traditional treatment planning. FORT was also associated with higher agency cost-effectiveness and a better average benefit-cost ratio, even when considering diagnosis, baseline symptoms, and education. Although the comparison groups were not completely equivalent, the findings suggest computerized decision support systems that collaborate with human decision-makers to personalize psychiatric rehabilitation and address critical decisions may have a role in improving treatment effectiveness and efficiency.

    Effects of the Indianapolis Vocational Intervention Program (IVIP) on defeatist beliefs, work motivation, and work outcomes in serious mental illness
    (Elsevier, 2017-04) Mervis, Joshua E.; Fiszdon, Joanna M.; Lysaker, Paul H.; Nienow, Tasha M.; Mathews, Laura; Wardwel, Patricia; Petrik, Tammy; Thime, Warren; Choi, Jimmy; Medicine, School of Medicine
    Defeatist beliefs and amotivation are prominent obstacles in vocational rehabilitation for people with serious mental illnesses (SMI). The CBT-based Indianapolis Vocational Intervention Program (IVIP) was specifically designed to reduce defeatist beliefs related to work functioning. In the current study, we examined the impact of IVIP on defeatist beliefs and motivation for work, hypothesizing that IVIP would be associated with a reduction in defeatist beliefs and greater motivation for work. We also examined the effects of IVIP on these variables as well as work outcomes during a 12-month follow-up. Participants with SMI (n=64) enrolled in a four-month work therapy program were randomized to IVIP or a support therapy group (SG). Assessments were conducted at baseline, post-treatment (4months), and follow-up (1year). Compared to those in SG condition, individuals randomized to IVIP condition reported greater reductions in defeatist beliefs and greater motivation for work at follow-up, along with greater supported employment retention rates. Specifically treating and targeting negative expectations for work therapy improves outcomes, even once active supports of the IVIP program and work therapy are withdrawn.

    Metacognition Is Necessary for the Emergence of Motivation in People With Schizophrenia Spectrum Disorders: A Necessary Condition Analysis
    (Wolters Kluwer, 2017-12) Luther, Lauren; Bonfils, Kelsey A.; Firmin, Ruth L.; Buck, Kelly D.; Choi, Jimmy; Dimaggio, Giancarlo; Popolo, Raffaele; Minor, Kyle S.; Lysaker, Paul H.; Psychology, School of Science
    Metacognition deficits are a putative cause of reduced motivation in people with schizophrenia spectrum disorders. However, it is unclear whether certain levels of metacognition are necessary for motivation to emerge. This study used a Necessary Condition Analysis (NCA) to test whether metacognition was necessary for the presence of motivation and to identify the minimum level of metacognition necessary for high motivation to be possible in people with schizophrenia spectrum disorders (N=175). Participants completed clinician-rated measures of metacognition and motivation. NCA revealed that metacognition is a necessary condition for motivation and that high levels of motivation were only possible, although not guaranteed, when at least a basic level of metacognition was present. Findings suggest that metacognition is a necessary building block for the development of motivation. Results suggest that targeting metacognition may be essential for improving motivation among people with schizophrenia spectrum disorders who do not meet this metacognition threshold.
