The current study examined whether age and frequent cannabis use interact to influence the trajectories of positive and negative schizotypy over time. Participants were 155 cannabis users, aged 15-24 years old, assessed over a 12-month period at 6-monthly intervals. The analyses examined the influence of age, frequent use, and time on positive and negative schizotypy. The current study found that among frequent cannabis users, younger age was associated with increased negative schizotypy over time, while among occasional cannabis users, younger age was associated with decreasing negative schizotypy over time. The current findings have implications for understanding how cannabis use may influence psychosis risk differently depending on age and frequency of use, as well as bring together past mixed findings on the relationship between negative schizotypy and cannabis use.

Article Synopsis
- Research shows that migrant status and ethnic minority background increase the risk of psychosis, but it's unclear if this also applies to subclinical psychosis.
- In a study with 460 participants, first and second-generation migrants, as well as certain ethnic minorities, reported higher levels of negative psychotic traits compared to a reference population.
- These findings suggest a connection between negative schizotypal traits and migrant/ethnic status, indicating a need for specific mental health interventions to support these groups and prevent the development of psychotic disorders.

Background: Recent research shows that individuals exhibiting schizotypal traits (ST) are more prone to developing other psychiatric disorders such as anxiety and depression. Regarding the relationship between empathy and schizotypy, a considerable degree of heterogeneity has been observed. The objective of this study was to describe the presence of ST in college students and the relationships among ST, psychiatric symptoms, and empathy.

Objective: The present study aimed to examine facial emotion recognition in a sample from the general population with elevated schizotypal traits, as defined by the four-factor model of schizotypy, and the association of facial emotion recognition and the schizotypal dimensions with psychological well-being.
Method: Two hundred and thirty-eight participants were allocated into four schizotypal groups and one control group. Following a cross-sectional study design, facial emotion recognition was assessed with a computerized task that included images from the Radboud Faces Database, schizotypal traits were measured with the Schizotypal Personality Questionnaire, and psychological well-being was evaluated with the Flourishing scale.
Impact of Overall and Specific Dimensions of Schizotypy on Theory of Mind.
Psychopathology

Background: Impairments in theory of mind (ToM) are highly prevalent among individuals with schizophrenia, resulting in substantial functional deficits. However, research on impairments in individuals with schizotypy has yielded inconsistent findings, with some studies finding ToM deficits in overall schizotypy, other studies finding ToM deficits in only specific schizotypy dimensions, and yet other studies finding no ToM deficits at all. One potential key factor that may account for this discrepancy is the use of schizotypy measures that do not adequately measure specific schizotypy dimensions.
