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 Science
Objectives 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.
Affective Empathy in Schizophrenia: A Meta-Analysis
(Elsevier, 2016-08) Bonfils, Kelsey A.; Lysaker, Paul H.; Minor, Kyle S.; Salyers, Michelle P.; Department of Psychiatry, IU School of Medicine
Background Affective empathy, or the emotional response one has to the experiences or emotional states of others, contributes to relationship-maintaining behaviors and is key in fostering social connections, yet no work has synthesized the body of literature for people with schizophrenia. The aim of the present meta-analysis was to determine the extent to which those diagnosed with schizophrenia experience deficits in affective empathy. Methods A literature search was conducted of studies examining empathy. Data were analyzed using a random effects meta-analytic model with Hedges' g standardized mean difference effect size. Results Individuals with schizophrenia exhibited significant, medium deficits in affective empathy (k = 37). Measurement type moderated the affective empathy deficit such that performance-based measures showed larger schizophrenia group deficits than self-report measures. Conclusion Consistent, significant deficits in affective empathy were found comparing people with schizophrenia to healthy controls, especially when using performance-based assessments. The medium effect suggests an important role for empathy in the realm of social cognitive research, and points to the need for further investigation of measurement techniques and associations with functional outcomes.
Affective Systems Induce Formal Thought Disorder in Early-Stage Psychosis
(APA, 2016-05) Minor, Kyle S.; Marggraf, Matthew P.; Davis, Beshaun J.; Mehdiyoun, Nicole F.; Breier, Alan; Department of Psychology, School of Science
Although formal thought disorder (FTD) has been described since early conceptualizations of psychosis, its underlying mechanisms are unclear. Evidence suggests FTD may be influenced by affective and cognitive systems; however, few have examined these relationships—with none focusing on early-stage psychosis (EP). In this study, positive FTD and speech production were measured in sex- and race-matched EP (n = 19) and healthy control (n = 19) groups by assessing “reactivity”—a change in experimental compared with baseline conditions—across baseline, affective, and cognitive conditions. Relationships with functioning were also examined within each group. Three key findings emerged: (a) the EP group displayed large differences in positive FTD and speech production, (b) those with EP exhibited affective reactivity for positive FTD, and (c) positive FTD and affective reactivity were linked with poor real-world functioning in EP and these relationships did not considerably change when controlling for positive symptom (e.g., delusions, hallucinations) severity. Our findings provide preliminary evidence that affective, but not cognitive, systems play a critical role in positive FTD. Affective reactivity, in particular, may aid in predicting those with EP who go on to develop serious social impairments. Future work should focus on whether affective systems differentially influence those at separate points on the psychosis-spectrum in an effort to establish evidence-based treatments for FTD.
Category fluency in psychometric schizotypy: How altering emotional valence and cognitive load affects performance
(Taylor & Francis, 2015) Minor, Kyle S.; Luther, Lauren; Auster, Tracey L.; Marggraf, Matthew P.; Cohen, Alex S.; Department of Psychology, School of Science
Introduction. In clinical high-risk populations, category fluency deficits are associated with conversion to psychosis. However, their utility as clinical risk markers is unclear in psychometric schizotypy, a group experiencing schizophrenia-like traits that is at putative high risk for psychosis. Methods. We examined whether introducing affective or cognitive load, two important stress vulnerability markers, altered category fluency performance in schizotypy (n = 42) and non-schizotypy (n = 38) groups. To investigate this question, we developed an experimental paradigm where all participants were administered category fluency tests across baseline, pleasant valence, unpleasant valence, and cognitive load conditions. Results. Compared to the non-schizotypy group, those with schizotypy performed significantly worse in pleasant and unpleasant valence conditions, but not cognitive load or baseline fluency tests. Conclusions. This study demonstrated the role of affect – but not cognitive load – on category fluency in psychometric schizotypy, as group differences only emerged once affective load was introduced. One explanation for this finding is that semantic memory may be unimpaired under normal conditions in psychometric schizotypy, but may be compromised once affective load is presented. Future studies should examine whether fluency deficits – particularly when affect is induced – predict future conversion to psychosis in psychometric schizotypy cohorts.
A cognitive model of diminished expression in schizophrenia: The interface of metacognition, cognitive symptoms and language disturbances
(Elsevier, 2020-12) García-Mieres, Helena; Lundin, Nancy B.; Minor, Kyle S.; Dimaggio, Giancarlo; Popolo, Raffaele; Cheli, Simone; Lysaker, Paul H.; Psychology, School of Science
The resistance of negative symptoms to pharmacologic treatment has spurred interest in understanding the psychological factors that contribute to their formation and persistence. However, little is understood about the psychological processes that reinforce and sustain the negative symptoms domain of diminished expression. Prior research has shown that higher levels of diminished expression relate to deficits in metacognitive capacity. We propose a more complex model in which diminished expression occurs when impairments in metacognitive self-reflectivity, alterations in higher-order language structure, and cognitive symptoms interact and thus interfere with persons' ability to understand and express emotions in ways others can recognize. Individuals with schizophrenia-spectrum disorders (N = 201) provided personal narratives detailing their life story and reflections about their mental illness. Self-reflectivity was measured with the Metacognition Assessment Scale-Abbreviated, and situation models were extracted from participants' personal narratives via Coh-Metrix 3.0, an automated program that calculates language indices. Diminished expression and cognitive symptoms were measured with the Positive and Negative Syndrome Scale. Structural equation models (SEM) examined whether self-reflectivity mediated the impact of cognitive symptoms and situation models on diminished expression. Results of the SEM revealed that self-reflectivity partially mediated the impact of situation models on diminished expression (β = -.073, p = .008, ±95% CI [-0.126, -0.019]). and fully mediated the influence of cognitive symptoms in diminished expression (β = 0.099, p = .001, ±95% CI [0.038, 0.160]). In conclusion, results suggest that self-reflectivity, linguistic cohesion, and cognitive symptoms may be useful targets for intervention in efforts to treat diminished expression in psychosis.
Conceptual Disorganization Weakens Links in Cognitive Pathways: Disentangling Neurocognition, Social Cognition, and Metacognition in Schizophrenia
(Elsevier, 2015-12) Minor, Kyle S.; Marggraf, Matthew P.; Davis, Beshaun J.; Luther, Lauren; Vohs, Jenifer L.; Buck, Kelly D.; Lysaker, Paul H.; Department of Psychology, School of Science
Disentangling links between neurocognition, social cognition, and metacognition offers the potential to improve interventions for these cognitive processes. Disorganized symptoms have shown promise for explaining the limiting relationship that neurocognition holds with both social cognition and metacognition. In this study, primary aims included: 1) testing whether conceptual disorganization, a specific disorganized symptom, moderated relationships between cognitive processes, and 2) examining the level of conceptual disorganization necessary for links between cognitive processes to break down. To accomplish these aims, comprehensive assessments of conceptual disorganization, neurocognition, social cognition, and metacognition were administered to 67 people with schizophrenia-spectrum disorders. We found that conceptual disorganization significantly moderated the relationship between neurocognition and metacognition, with links between cognitive processes weakening when conceptual disorganization is present even at minimal levels of severity. There was no evidence that conceptual disorganization—or any other specific disorganized symptom—drove the limiting relationship of neurocognition on social cognition. Based on our findings, conceptual disorganization appears to be a critical piece of the puzzle when disentangling the relationship between neurocognition and metacognition. Roles of specific disorganized symptoms in the neurocognition – social cognition relationship were less clear. Findings from this study suggest that disorganized symptoms are an important treatment consideration when aiming to improve cognitive impairments.
Development and preliminary validation of the romantic relationship functioning scale
(2014) Bonfils, Kelsey A.; Salyers, Michelle P.; Minor, Kyle S.; McGrew, John H., 1953-; Grahame, Nicholas J.
Background: Research has repeatedly shown that individuals with severe mental illness desire interpersonal and romantic relationships and that social support (including spousal relationships) is beneficial. In addition, social deficits in mental disorders can often get in the way of developing fulfilling relationships. However, there is little currently available to help clinicians and researchers assess romantic relationship functioning in those with mental illness. The aim of this pilot study was to examine reliability and validity of a new measure of functioning in romantic relationships, the Romantic Relationship Functioning Scale (RRFS). Method: The RRFS was constructed based on theory proposed by Redmond, Larkin, and Harrop (2010). In an analog study, we tested the measure in a sample of college students (N=387), examining reliability, stability over time, factor structure, and relationships with measures of psychopathology and related measures of social functioning to assess convergent validity. Results: The RRFS exhibited a hierarchical four-factor structure, supporting the use of a total score. Although subscales were supported in the factor analysis, other psychometric evidence was weaker, and the use of a total score is advocated. Internal consistency and test-retest reliability were acceptable for the total scale (>.8). The RRFS had moderate to large correlations in the expected direction with all psychopathology measures. In predictive models, overall mental health, social functioning, and fewer interpersonal difficulties predicted higher romantic relationship functioning. Conclusions: The RRFS total score shows preliminary evidence of reliability and validity. The RRFS has potential to be of use in treatment centers for undergraduates and for individuals with diagnosed mental disorders. Future research should further investigate the RRFS subscales and the measure’s performance in clinical samples.
Disorganized Speech and Metacognition in Schizophrenia: Differential Relations and a Comparison of Behavioral Speech Measures
(2021-08) Myers, Evan J.; Minor, Kyle S.; Salyers, Michelle P.; Lysaker, Paul H.
Disorganized speech is a core feature of schizophrenia. It is a key component of formal thought disorder (FTD). Recent work has tied disorganized speech to deficits in metacognition, or one’s ability to integrate experiences to form complex mental representations. In this study, we aimed to 1) explore the relationship between disorganized speech and metacognition and 2) compare trained rater and emerging automated analysis methods. Positive and Negative Syndrome Scale (PANSS) and Indiana Psychiatric Illness Interviews (IPII) were conducted; the IPII was coded for disorganized speech using the Communication Disturbances Index (CDI) and Coh-Metrix multidimensional indices. Metacognition was rated using the Metacognition Assessment Scale. We compared FTD (n = 16; PANSS conceptual disorganization ≥ 3) and non-FTD (n = 29; PANSS conceptual disorganization < 3) groups on metacognition and examined CDI and Coh-Metrix’s ability to account for variance in metacognition. We hypothesized that the FTD group would have lower metacognition and that both CDI and Coh-Metrix would account for significant variance in metacognition. Analyses indicated metacognition did not differ between groups and neither measure accounted for significant variance in metacognition. Results also showed that the CDI was able to distinguish the groups. Overall, results suggest little relationship between FTD and metacognition. Findings also indicate that trained rater measures of disorganized speech may have clinical utility in classifying FTD. Future research examining these constructs should address important limitations of this study by ensuring adequate levels of FTD in the study sample and by assessing neurocognition.
The effect of limited cognitive resources on communication disturbances in serious mental illness
(Elsevier, 2017-02) Le, Thanh P.; Najolia, Gina M.; Minor, Kyle S.; Cohen, Alex S.; Psychology, School of Science
Semantically incoherent speech is a pernicious clinical feature of serious mental illness (SMI). The precise mechanisms underlying this deficit remain unclear. Prior studies have found that arousal of negative emotion exaggerates the severity of these communication disturbances; this has been coined "affective reactivity". Recent research suggests that "cognitive reactivity" may also occur, namely reflecting reduced "on-line" cognitive resources in SMI. We tested the hypothesis that communication disturbances manifest as a function of limited cognitive resources in SMI above and beyond that associated with state affectivity. We also investigated individual differences in symptoms, cognitive ability, and trait affect that may be related to cognitive reactivity. We compared individuals with SMI (n=52) to nonpsychiatric controls (n=27) on a behavioral-based coding of communication disturbances during separate baseline and experimentally-manipulated high cognitive-load dual tasks. Controlling for state affective reactivity, a significant interaction was observed such that communication disturbances decreased in the SMI group under high cognitive-load. Furthermore, a reduction in communication disturbances was related to lower trait and state positive affectivity in the SMI group. Contrary to our expectations, limited cognitive resources temporarily relieved language dysfunction. Implications, particularly with respect to interventions, are discussed.
Emotional Expression: Novel Measures and Relation to Emotion Recognition in Schizotypy
(Office of the Vice Chancellor for Research, 2015-04-17) Martin, Kelsey E.; Minor, Kyle S.
This study investigated emotional expression and emotion recognition in a psychometric schizotypy sample of individuals with subclinical traits which are related to psychotic disorders. Both emotional expression and emotion recognition have been observed to be diminished in schizotypy, although there is conflicting evidence when considering of multiple studies. Using a novel measure of emotional expression that relies upon observation informed by objective criteria as well as utilizing facial recognition software, the study proposes three main hypotheses: 1) Emotion recognition skill will be poorer and the frequency and average magnitude of emotional expression will be lower in the schizotypy group compared to the non-schizotypy group; 2) Facial recognition software will demonstrate high convergent validity with the observational measure; 3) Emotion recognition skill will be positively correlated with levels of emotional expression, as measured by observer ratings and software, in both schizotypy and nonschizotypy groups. For each of these hypotheses, there is no expected variation with regards to any specific basic emotion (happiness, sadness, surprise, fear, anger, or disgust), and tests will determine if this prediction is supported. Participants with schizotypy (n = 17) and without (n =14) completed an emotion recognition measure and a semi-structured interview which was video recorded. This video was processed through both measures. Data analysis is still in process, with preliminary results showing small differences between groups in emotional expression for negative affect only.
