This randomized controlled trial examined the effects of monetary versus point-based rewards on effort-cost decision-making in individuals at clinical high risk for psychosis (CHR) and healthy controls. The study found that participants expended greater effort when rewarded with money (b = 0.13, p = 0.018), while negative symptom severity in CHR individuals was linked to reduced effort (b = -0.03, p = 0.016).
Key findings
- Participants expended greater effort with money rewards compared to point-based rewards (b = 0.13, p = 0.018).
- CHR individuals with higher negative symptom severity expended less effort (b = -0.03, p = 0.016).
- No interaction was found between CHR status and reward type (b = 0.07, p = 0.845).
- Higher household income correlated with less effort in high reward, high probability trials in the money condition (b = -0.24, p = 0.046).
Why it matters
Understanding how different reward types influence effort in individuals at clinical high risk for psychosis can inform the design of behavioral assessments and interventions. This knowledge may enhance engagement and improve outcomes in clinical settings.
