Item Additional Support for the Cognitive Model of Schizophrenia: Evidence of Elevated Defeatist Beliefs in Schizotypy(Elsevier, 2016-07) Luther, Lauren; Salyers, Michelle P.; Firmin, Ruth L.; Marggraf, Matthew P.; Davis, Beshaun; Minor, Kyle S.; Department of Psychology, School of ScienceObjectives The cognitive model of poor functioning in schizophrenia posits that defeatist performance beliefs—overgeneralized negative beliefs about one's ability to perform tasks—develop prior to the onset of psychosis and contribute to the development and maintenance of negative symptoms and poor functioning. Although several studies with schizophrenia samples have provided support for the model, there is a paucity of research investigating these beliefs in individuals with schizotypy—those exhibiting traits reflecting a putative genetic liability for schizophrenia. This study had two aims: to examine whether defeatist performance beliefs (1) are elevated in schizotypy compared to controls and (2) are associated with decreased quality of life and working memory and increased negative but not positive schizotypy traits in the schizotypy group. Methods Schizotypy (n = 48) and control (n = 53) groups completed measures of schizotypy traits, defeatist performance beliefs, quality of life, and working memory. Results Analyses revealed that the schizotypy group reported significantly more defeatist performance beliefs than the control group. Within the schizotypy group, increased defeatist performance beliefs were significantly associated with greater negative schizotypy traits and lower quality of life. No significant associations were observed between defeatist performance beliefs and positive schizotypy traits and working memory. Conclusions Results generally support the theoretical validity of the cognitive model of poor functioning in schizophrenia and suggest that elevated defeatist performance beliefs may contribute to the manifestation of subclinical negative symptom traits and reduced quality of life among those with a latent vulnerability for schizophrenia.Item Evaluating Social Interactions in Schizotypy Using Ecological Momentary Assessment(2024-08) Russell, Madisen T.; Minor, Kyle S.; Salyers, Michelle P.; Wu, WeiCompared 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.Item Schizotypy in an online sample: Associations with functioning, wellbeing, and stigma toward psychological treatment(Office of the Vice Chancellor for Research, 2016-04-08) Dempsey, Abigail E.; Bonfils, Kelsey A.; Firmin, Ruth L.; Salyers, Michelle P.Background: Social functioning and positive attitudes toward treatment have been strongly linked with recovery in people with schizophrenia, yet less is known for schizotypy – traits that are associated with risk for schizophrenia. Previous studies of schizotypy have used primarily undergraduate or small community samples. The aim of the current study was to investigate correlates of schizotypy in a large online sample. We hypothesized that people with schizotypy traits would report lower functioning, well-being, and greater stigmatizing attitudes regarding treatment. Methods: In a sample (N=856) recruited using Amazon’s Mechanical Turk (MTurk), participants were dichotomized into non-schizotypy or schizotypy groups based on their endorsement of schizotypal traits on the Schizotypal Personality Questionnaire – Brief Revised (SPQ-BR; schizotypy group n=101; non-schizotypy group n=431). Participants completed a demographic survey and several measures related to functioning, well-being, and stigma, including the Romantic Relationship Functioning Scale (RRFS), the Social Adjustment Scale – Self-Report: Screener (SAS-SR: Screener), the SPQ-BR, the Short Form-12 Health Survey (SF-12), and the Stigma Scale for Receiving Psychological Help (SSRPH). Independent-samples t-tests were conducted to compare schizotypy groups on these variables. Results: Those who reported high levels of schizotypy reported significantly poorer social functioning, t(122.74)=-10.66, p<.001; poorer romantic relationship functioning, t(129.01)=12.00, p<.001; poorer mental wellbeing ,t(132.58)=13.42, p=.001; and greater stigma toward receiving psychological treatment, t(137.06)=-3.89, p=.037. There was no significant difference in physical wellbeing. Discussion: These findings support the use of online samples and suggest schizotypy is associated with poorer functioning and wellbeing and increased stigma toward seeking treatment. Results support the emergence of deficits in key social domains among those at risk for developing greater psychosis symptoms. Given the links between these deficits and attitudes and poorer functioning in clinical samples, these findings suggest social functioning and help-seeking attitudes may be important targets of early intervention services.Item Semantic coherence in psychometric schizotypy: An investigation using Latent Semantic Analysis(Elsevier, 2018-01) Marggraf, Matthew P.; Cohen, Alex S.; Davis, Beshaun J.; DeCrescenzo, Paula; Bair, Natasha; Minor, Kyle S.; Psychology, School of ScienceTechnological advancements have led to the development of automated methods for assessing semantic coherence in psychiatric populations. Latent Semantic Analysis (LSA) is an automated method that has been used to quantify semantic coherence in schizophrenia-spectrum disorders. The current study examined whether: 1) Semantic coherence reductions extended to psychometrically-defined schizotypy and 2) Greater cognitive load further reduces semantic coherence. LSA was applied to responses generated during category fluency tasks in baseline and cognitive load conditions. Significant differences between schizotypy and non-schizotypy groups were not observed. Findings suggest that semantic coherence may be relatively preserved at this point on the schizophrenia-spectrum.Item Speech production and disorganization in schizotypy: Investigating the role of cognitive and affective systems(Elsevier, 2019) Marggraf, Matthew P.; Davis, Beshaun J.; Hardin, Kat L.; Abplanalp, Samuel J.; Haller, Jennifer A.; DeCrescenzo, Paula; Minor, Kyle S.; Psychology, School of ScienceDiminished productivity and elevated disorganization have been detected in the speech of individuals with schizotypy. However, the underlying mechanisms for these disruptions are not well understood. Separate lines of research suggest potential contributions from cognitive and affective systems. In this study, disorganized speech and speech production were examined in speech samples generated by schizotypy (n = 47) and non-schizotypy (n = 51) groups by assessing “reactivity” (i.e., a change in experimental compared with baseline conditions) across baseline, affective, and dual-task (i.e., cognitive) conditions. Relationships with social functioning were also examined within each group. Three key findings emerged: 1) compared to the non-schizotypy group, those with schizotypy exhibited diminished speech production in the affective condition and affective reactivity was observed; 2) the schizotypy group displayed greater levels of disorganized speech in dual-task conditions and cognitive reactivity was observed; and 3) affective reactivity for disorganized speech was linked to worse social functioning within the schizotypy group. This study provides evidence that cognitive and affective systems are uniquely involved in separate characteristics of speech in schizotypy. At this stage, cognitive systems appear to have a specific role in the organization of speech, whereas affective systems are more heavily involved in speech production. Regarding the association between affective reactivity and social functioning, previous research has demonstrated individuals highly reactive to emotional stimuli carry additional risk for conversion to psychosis. Future research identifying a subset with schizotypy who demonstrate affective reactivity could lead to a better understanding of links between schizotypy and future psychosis symptoms.Item A test of the cognitive model of negative symptoms: Associations between defeatist performance beliefs, self-efficacy beliefs, and negative symptoms in a non-clinical sample(Elsevier, 2018-11) Luther, Lauren; Coffin, George M.; Firmin, Ruth L.; Bonfils, Kelsey A.; Minor, Kyle S.; Salyers, Michelle P.; Psychology, School of ScienceThe cognitive model of negative symptoms posits that defeatist performance beliefs—overgeneralized negative beliefs about one's ability to successfully perform tasks—contribute to the development and maintenance of negative symptoms. However, a conceptually similar construct, reduced generalized self-efficacy—diminished confidence in one's ability to effectively complete or respond to new or challenging tasks and situations—has also been linked to negative symptoms. To identify which beliefs might be most important to target to reduce negative symptoms, we examined: 1) the association between defeatist performance and self-efficacy beliefs and 2) which beliefs are more strongly associated with negative symptoms in a non-clinical sample of young adults (N = 941). Analyses revealed a significant, medium-sized correlation between defeatist performance and self-efficacy beliefs. Both beliefs types were significantly associated with negative symptoms, but defeatist performance beliefs were more strongly related to negative symptoms than self-efficacy beliefs. Defeatist performance and self-efficacy beliefs appear to be distinct yet overlapping constructs. Findings support the cognitive model and indicate that defeatist performance beliefs may have a greater role in the manifestation of negative symptoms than self-efficacy beliefs. Thus, defeatist performance beliefs may be a uniquely promising treatment target for reducing or preventing negative symptoms.Item Using Lexical Analysis to Link Depression in Schizotypy(Office of the Vice Chancellor for Research, 2016-04-08) Abplanalp, Samuel J.; Minor, Kyle S.Introduction: Previous research has suggested that depression is a major symptom of schizophrenia, and, moreover, schizotypy. Speech has also been heavily studied within the schizophrenia-spectrum. Compared to healthy populations, those with schizotypy tend to show greater depression and use negative affect (emotion) words more frequently. Speech containing negative affect words has also been shown to correlate with depression in both the healthy population and the schizophrenia-spectrum. This study aimed to examine any differences in depression level and negative affect words between a schizotypy and control sample, and also if depression level can be linked to speech within schizotypy. Methods: 38 participants partook in an open-ended, semi-structured interview-25 making up the schizotypy group, and 13 in the non-schizotypy group. The interview was recorded, transcribed, and ran through Lexical Inquiry Word Count (LIWC), a computerized measure that evaluates speech content using a dictionary that contains over 4500 words/word stems across 68 categories. Participants were also administered two depression questionnaires. Results: The schizotypy sample showed significantly greater depression than controls (p<.01, d= 1.55; p<.01, d= -2.91) comparing both questionnaires. There were no significant differences between the groups with relation to negative affect words, but a trend effect was shown, with the schizotypy group using these words with greater frequency (p>.05, d= -.54).Within schizotypy, a trend level relationship between depression and negative affect words was observed (r= -.31, p>.05). Conclusion: These findings are consistent with previous studies reporting higher depression levels in the schizophrenia-spectrum compared to healthy populations. It is inconsistent, however, with regards to schizotypy and use of negative emotion words, which may be due in part to low power. Furthermore, this study shows that lexical analysis software has the potential to assist in the measurement of depression in schizotypy.Item Words matter: Implementing the electronically activated recorder in schizotypy(APA, 2018) Minor, Kyle S.; Davis, Beshaun J.; Marggraf, Matthew P.; Luther, Lauren; Robbins, Megan L.; Psychology, School of ScienceIn schizophrenia-spectrum populations, analyzing the words people use has offered promise for unlocking information about affective states and social behaviors. The electronically activated recorder (EAR) is an application-based program that is combined with widely used smartphone technology to capture a person’s real-world interactions via audio recordings. It improves on the ecological validity of current methodologies by providing objective and naturalistic samples of behavior. This study is the first to implement the EAR in people endorsing elevated traits of schizophrenia-spectrum personality disorders (i.e., schizotypy), and we expected the EAR to (a) differentiate high and low schizotypy groups on affective disturbances and social engagement and (b) show that high schizotypy status moderates links between affect and social behavior using a multimethod approach. Lexical analysis of EAR recordings revealed greater negative affect and decreased social engagement in those high in schizotypy. When assessing specific traits, EAR and ecological momentary assessment (EMA) converged to show that positive schizotypy predicted negative affect. Finally, high schizotypy status moderated links between negative affect and social engagement when the EAR was combined with EMA. Adherence did not influence results, as both groups wore the EAR more than 90% of their waking hours. Findings supported using the EAR to assess real-world expressions of personality and functioning in schizotypy. Evidence also showed that the EAR can be used alongside EMA to provide a mixed-method, real-world assessment that is high in ecological validity and offers a window into the daily lives of those with elevated traits of schizophrenia-spectrum personality disorders.
