    Differential Risk: Gender and Racial Differences in the Relationship between Trauma, Discrimination, and Schizotypy
    (MDPI, 2024-04-25) Monette, Mahogany A.; Russell, Madisen T.; Abel, Danielle B.; Lewis, Jarrett T.; Mickens, Jessica L.; Myers, Evan J.; Hricovec, Megan M.; Cicero, David C.; Wolny, J.; Hetrick, William P.; Masucci, Michael D.; Cohen, Alex S.; Burgin, Christopher J.; Kwapil, Thomas R.; Minor, Kyle S.; Psychology, School of Science
    Traumatic experiences are associated with increased experiences of positive schizotypy. This may be especially important for People of Color, who experience higher rates of trauma and racial discrimination. No study to date has examined how racial disparities in traumatic experiences may impact schizotypy. Furthermore, of the studies that have examined the relationship between trauma and schizotypy, none have examined racial discrimination as a potential moderator. The present study examined if racial discrimination moderates the relationship between trauma and multidimensional (positive, negative, and disorganized) schizotypy. In a sample of 770 college students, we conducted chi-squared analyses, analyses of variance, and stepwise regressions. We found that Black students experienced significantly higher racial discrimination and trauma than Latinx and Asian students. Furthermore, Black and Latinx students experienced significantly more multidimensional schizotypy items than Asian students. Trauma and racial discrimination explained 8 to 23% of the variance in each dimension of schizotypy. Racial discrimination did not moderate the relationships between trauma and multidimensional schizotypy. Our findings suggest that we need to examine risk factors that may prevent recovery from psychotic disorders. Additionally, disorganized schizotypy showed the most robust associations and may be a critical site of intervention.

    Evaluating Social Interactions in Schizotypy Using Ecological Momentary Assessment
    (2024-08) Russell, Madisen T.; Minor, Kyle S.; Salyers, Michelle P.; Wu, Wei
    Compared to individuals low in schizotypal traits, those with elevated schizotypal traits present with social deficits and are at greater risk for developing schizophrenia-spectrum disorders and other forms of psychopathology. Ecological Momentary Assessment (EMA) is a powerful tool for understanding the real-world behaviors of schizophrenia-spectrum populations. Although studies have effectively utilized EMA to examine important aspects of social interactions (i.e., how often people interact [likelihood], the complexity of the content in these interactions [depth], and how much pleasure they derive from these interactions [enjoyment]) in people with schizophrenia, few have explored differences in social interactions using EMA across schizotypal traits (i.e., positive, negative, and disorganized). In this study, we used EMA to collect data from three universities. Our primary aim was to evaluate if positive, negative, and disorganized schizotypal traits in college students were significantly linked to individuals’ likelihood, depth, and enjoyment of social interactions in their everyday lives. Our secondary aim was to investigate whether affect and stress play a role in individuals’ likelihood, depth, and enjoyment of social interactions. Results revealed that negative schizotypal traits more strongly predicted social interaction depth and enjoyment compared to positive and disorganized traits. Contrary to hypotheses, positive affect was a better predictor of social interaction outcomes than negative affect and stress. Several notable interactions between schizotypal traits and affect also emerged. Overall, this study increases understanding of how schizotypal traits and affect impact daily social interactions. These findings may inform future research aimed at improving and individualizing interventions for social functioning deficits in individuals with elevated positive, negative, and/or disorganized schizotypal traits.

    Identity recognition from faces and bodies in schizophrenia spectrum disorders
    (Elsevier, 2024-03-07) Russell, Madisen T.; Hajdúk, Michal; Springfield, Cassi R.; Klein, Hans S.; Bass, Emily L.; Mittal, Vijay A.; Williams, Trevor F.; O'Toole, Alice J.; Pinkham, Amy E.; Psychology, School of Science
    Deficits in facial identity recognition and its association with poor social functioning are well documented in schizophrenia, but none of these studies have assessed the role of the body in these processes. Recent research in healthy populations shows that the body is also an important source of information in identity recognition, and the current study aimed to thoroughly examine identity recognition from both faces and bodies in schizophrenia. Sixty-five individuals with schizophrenia and forty-nine healthy controls completed three conditions of an identity matching task in which they attempted to match unidentified persons in unedited photos of faces and bodies, edited photos showing faces only, or edited photos showing bodies only. Results revealed global deficits in identity recognition in individuals with schizophrenia (ηp2 = 0.068), but both groups showed better recognition from bodies alone as compared to faces alone (ηp2 = 0.573), suggesting that the ability to extract useful information from bodies when identifying persons may remain partially preserved in schizophrenia. Further research is necessary to understand the relationship between face/body processing, identity recognition, and functional outcomes in individuals with schizophrenia-spectrum disorders.

    Social Activity in Schizotypy: Measuring Frequency and Enjoyment of Social Events
    (MDPI, 2024-06-05) DeBats, Candice C.; Abel, Danielle B.; Sullivan, Morgan M.; Koesterer, Sophia C.; Linton, Imani S.; Mickens, Jessica L.; Russell, Madisen T.; Hammer, Lillian A.; Minor, Kyle S.; Psychology, School of Science
    Improving social functioning deficits-a core characteristic of schizophrenia-spectrum disorders-is often listed by patients as a key recovery goal. Evidence suggests that social deficits also extend to people with schizotypy, a group at heightened risk for psychotic and other psychopathological disorders. One challenge of social functioning research in schizotypy is understanding whether social deficits arise from receiving less pleasure from social activities or from participating less in high-pleasure activities. However, limited information exists on what constitutes highly pleasurable, common social activities. In this study, 357 college students rated the frequency and enjoyment of 38 social activities. Our aims were to categorize activities based on their frequency and enjoyment, and whether these correlated with validated social functioning and schizotypy measures. We found that social activities could be characterized based on their frequency and enjoyment and created a frequency-enjoyment matrix that could be useful for future studies. Activities were correlated with social functioning, generally reaching a small effect size level, with increasing frequency and enjoyment showing associations with greater social functioning. Further, negative and disorganized-but not positive-traits were associated with less engagement and pleasure. Although follow-up studies in community samples are needed, our findings have the potential to help researchers and clinicians better understand which activities participants are more likely to engage in and derive pleasure from. The findings may also illustrate the extent to which social deficits may be due to less engagement or less pleasure from social activities, as well as which aspects of schizophrenia-spectrum disorders are associated with these facets of social functioning.
