Principles of Individual Placement and Support (IPS) Model
(Robert Drake & Deborah Becker) • Work rehabilitation is integral
component of mental health treatment, not separate (job specialist w/in clinical team)
• Goal is competitive employment in typical work settings
• Emphasis is on obtaining jobs directly, rather than after lengthy pre-employment training
Principles of Individual Placement and Support (IPS) Model
(Robert Drake & Deborah Becker)
• Continuous vocational rehabilitation services based in real work experiences
• Follow-along support to sustain employment
• Services based on consumers’ preferences and choices
• Outreach into community

Medication Non-Adherence (from Peter Weiden)
• 50% of patients have significant non-adherence within one year of beginning treatment.
• 75% within two years. • 50% of the direct medical costs of
psychiatric hospitalization attributed to non-adherence.
UCLA Study Design • 12-month randomized controlled trial with first-
episode schizophrenia patients at the UCLA Aftercare Research Program
• Patients received Individual Placement and Support, a form of supported education and supported employment, to provide a context of active work rehabilitation
• After stabilization, patients were randomly
assigned to the medication condition and the psychosocial treatment condition (2 X 2 design)

Pilot Study of Adding Aerobic Exercise to Cognitive Training
• Increasing evidence that aerobic exercise releases neurotrophic factors (e.g., brain-derived neurotrophic factor) that stimulate synaptic plasticity and enhance learning
• We hypothesize that adding regular aerobic exercise to neuroplasticity-based cognitive training will increase cognitive gains

Overall Conclusions • Supported education/employment can
strikingly increase the proportion of patients who return to school or a job after an initial psychotic episode.
• Long-acting injectable antipsychotic medication is a promising strategy for reducing relapses and improving cognition and everyday functioning in recent-onset schizophrenia.
Overall Conclusions • Systematic cognitive training can impact
cognitive functioning and everyday functioning in the early course of schizophrenia.
• Aerobic exercise and cognitive training might have synergistic effects on learning and overall cognitive functioning that enhance the impact of cognitive training alone.
