Negative schizotypal traits predict reduction in effort-reward imbalance reward motivation
Summary: People with high schizotypal traits are more likely to perceive effort-reward imbalance. Researchers have found a link between effort-reward imbalance and reduced gray matter volume, and impaired resting-state functional connectivity in people with schizotypal traits.

Effort-reward imbalance (ERI) refers to the imbalance between high-effort commitment and low-reward outcome, i.e. when one perceives that he/she is expending more effort but gaining significantly. disproportionately fewer rewards, which is important for daily life functioning.
Recent findings suggest that participants with high levels of schizotypy are more likely to perceive ERI. Moreover, there is also a correlation between ERI and reduced gray matter volume and impaired resting-state functional connectivity in participants with a high level of schizotypy.
However, the underlying relationship between ERI and the motivation to reward is still well known. In particular, it is unclear whether the effects of ERI on motivation may vary in different subtypes of schizotypal groups.
To fill such a knowledge gap, Drs. Huang Jia and Raymond Chan of the Institute of Psychology, Chinese Academy of Sciences (CAS) and their collaborators conducted a study to determine whether the E/R ratio is related to reward motivation, and whether the relationship between ERI and reward motivation may be differentially moderated by schizotypal subtypes.
They recruited 843 college students to complete a set of online checklists specifically capturing schizotypal personality traits, ERI, and motivation. They then performed multiple linear regressions to build models to investigate the moderating effects of schizotypal traits on the relationship between ERI and reward motivation.
According to the researchers, a stressful ERI situation predicted reduction in reward motivation. However, the schizotypal subtypes showed differential predictive and moderating effects. In particular, negative schizotypal traits showed a significant negative moderating effect on the relationship between ERI and reward motivation, while positive and disorganized schizotypal traits had significant positive moderating effects.
Taken together, these results suggest that schizotypal trait subtypes differentially moderate the relationship between ERI and reward motivation and underscore the importance of developing specific intervention strategies to improve reward motivation and reward-oriented behavior. on targets in subclinical populations.

The schizotypal construct is useful for studying the effects of environmental stress on the development of subclinical negative symptoms. The relationship between self-reported motivation, effort-reward imbalance (ERI), and schizotypal characteristics has rarely been studied.
We sought to examine the possible moderating effect of schizotypal traits on ERI and reward motivation.
Eight hundred forty-three college students were recruited online to complete a set of self-reported measures capturing schizotypal traits, effort-reward imbalance, and reward motivation, namely the Schizotypal Personality Questionnaire (SPQ), Effort-Reward Imbalance – School Version Questionnaire (C-ERI-S) and Motivation and Pleasure Scale-Self Report (MAP-SR).
We performed multiple linear regression to build models to investigate the moderating effects of schizotypal traits on the relationship between ERI and reward motivation. A stressful ERI situation predicted reduction in reward motivation.
Negative schizotypal traits showed a significant negative moderating effect on the relationship between ERI and reward motivation, while positive and disorganized schizotypal traits had significant positive moderating effects. Schizotypal trait subtypes differentially moderate the relationship between ERI and reward motivation.
Only the negative schizotypal traits and the stressful ERI situation together negatively impact reward motivation.
