PATIENTS WITH SCHIZOPHRENIA EXPERIENCE1:
| || |
The prevalence of schizophrenia approaches 1% internationally.2
| || |
The incidence (the number of new cases annually) is about 1.5 per 10,000 people.2
| || |
Modal age of onset of schizophrenia is between 18 and 25 for men and between 25 and 35 for women, with a second peak occurring around menopause.3
The prognosis of schizophrenia is worse in men.4,5
Compared with the general population men and women with schizophrenia are at a greater risk for metabolic syndrome.7
Lifestyle and genetic factors contribute to metabolic risk independent of risk associated with antipsychotic treatment.6
RAISE Study 2-Year Outcomes8
Duration of untreated psychosis (<74 weeks) was a significant moderator of the treatment effect on Total Quality of Life Scale (ES 0.54) and PANSS scores (ES 0.42) over time.
Navigate-assigned patients had several positive significant differences in outcomes vs regular care:
- Remained in treatment longer
- More likely to have received outpatient services
- Greater improvement in quality of life over 2 years (p<0.02)
- More improvements were seen in the interpersonal and intrapsychic foundations (sense of purpose, motivation, curiosity, & emotional engagement) as well as engagements with common objects & activities
- Greater number of participants working or in school (p<0.05)
- Greater improvement on the PANSS (p<0.02) and Calgary Depression Scale (p<0.04)
- Reduced rate of hospitalization (p=NS)
The Recovery After an Initial Schizophrenia Episode (RAISE) Study8
RAISE aims to develop, test, and implement person-centered, integrated treatment approaches for first-episode psychosis that promote symptomatic and functional recovery
Assigned to “Navigate vs Regular Care”
Assessment Scales: Total Score of Heinrichs-Carpenter QOL scale assessing purpose, motivation, emotional & social interactions, role functioning and engagement in regular activities.
RAISE Study Arms
NAVIGATE-FOUR CORE INTERVENTIONS:

Heinrichs-Carpenter Quality of Life (QLS) Total Score and PANSS Total Score: Effects of Shorter or Longer Duration of Untreated Psychosis (DUP) Based on a Model With Square Root Transformation of Monthsa
a In the model, DUP and DUP by square root of time by treatment terms were included as covariates. The DUP by square root of time term was found not to be significant for either outcome. DUP=Duration of Untreated Psychosis; QLS=Quality of Life Score; PANSS=Positive and Negative Syndrome Scale; REG=Regular Care; NAV=NAVIGATE.
bDUP by treatment by square root of time interaction, p=0.003. cDUP by treatment by square root of time interaction, p=0.043.
