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 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 ScienceIntroduction. 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.Item Clarifying the Overlap Between Motivation and Negative Symptom Measures in Schizophrenia Research: A Meta-Analysis(Elsevier, 2019-04) Luther, Lauren; Fischer, Melanie W.; Firmin, Ruth L.; Salyers, Michelle P.; Psychology, School of ScienceMotivation and negative symptom research has recently been hampered by a series of inconsistent findings, leading to calls for a greater consensus on the type of measures used across studies. To inform this issue, we conducted a meta-analysis that quantified the association between motivation measures (self-report, performance-based) and clinician-rated negative symptom measures as well as a series of moderator analyses to develop a greater understanding of the measurement factors impacting this relationship. Forty-seven eligible studies with people with schizophrenia-spectrum disorders were included. Using a random-effects meta-analytic model, a small but significant overall effect size emerged between motivation and clinician-rated negative symptoms (r = −.18). Several significant moderators were identified, including the generation of negative symptom measures such that there was a significantly stronger relationship between motivation and second-generation (r = −.38) than first-generation negative symptom measures (r = −.17). Further, the type of performance-based measure used moderated the relationship, with effort discounting tasks most strongly related to negative symptoms (r = −.44). The domain of motivation assessed (intrinsic, extrinsic, amotivation) also moderated the relationship. These findings help to identify sources of inconsistencies observed in prior studies and point to both second-generation and effort discounting tasks as the most promising types of measures, particularly for those interested in validating motivation measures or assessing the effectiveness of motivation treatments. Although additional research is needed, our results suggest that using these measures may help to reduce inconsistencies across studies and move the field forward.Item A Comparative Effectiveness Trial to Reduce Burnout and Improve Quality of Care(Springer, 2019-03) Salyers, Michelle P.; Garabrant, Jennifer M.; Luther, Lauren; Henry, Nancy; Fukui, Sadaaki; Shimp, Dawn; Wu, Wei; Gearhart, Tim; Morse, Gary; York, Mary M.; Rollins, Angela L.; Psychology, School of ScienceClinician burnout is presumed to negatively impact healthcare quality; yet scant research has rigorously addressed this hypothesis. Using a mixed-methods, randomized, comparative effectiveness design, we tested two competing approaches to improve care—one addressing clinician burnout and the other addressing how clinicians interact with consumers—with 192 clinicians and 469 consumers at two community mental health centers. Although qualitative reports were promising, we found no comparative effectiveness for either intervention on burnout, patient-centered processes, or other outcomes. Discussion includes identifying ways to strengthen approaches to clinician burnout.Item 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 ScienceDisentangling 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.Item Consumer factors predicting level of treatment response to illness management and recovery(American Psychological Association, 2017-12) White, Dominique A.; McGuire, Alan B.; Roudebush, Richard L.; Luther, Lauren; Anderson, Adrienne; Phalen, Peter; McGrew, John H.; Psychology, School of ScienceOBJECTIVE: This study aims to identify consumer-level predictors of level of treatment response to illness management and recovery (IMR) to target the appropriate consumers and aid psychiatric rehabilitation settings in developing intervention adaptations. METHOD: Secondary analyses from a multisite study of IMR were conducted. Self-report data from consumer participants of the parent study (n = 236) were analyzed for the current study. Consumers completed prepost surveys assessing illness management, coping, goal-related hope, social support, medication adherence, and working alliance. Correlations and multiple regression analyses were run to identify self-report variables that predicted level of treatment response to IMR. RESULTS: Analyses revealed that goal-related hope significantly predicted level of improved illness self-management, F(1, 164) = 10.93, p < .001, R2 = .248, R2 change = .05. Additionally, we found that higher levels of maladaptive coping at baseline were predictive of higher levels of adaptive coping at follow-up, F(2, 180) = 5.29, p < .02, R2 = .38, R2 change = .02. Evidence did not support additional predictors. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Previously, consumer-level predictors of level of treatment response have not been explored for IMR. Although 2 significant predictors were identified, study findings suggest more work is needed. Future research is needed to identify additional consumer-level factors predictive of IMR treatment response in order to identify who would benefit most from this treatment program. (PsycINFO Database RecordItem Consumer Outcomes After Implementing CommonGround as an Approach to Shared Decision Making(APA, 2017-03) Salyers, Michelle P.; Fukui, Sadaaki; Bonfils, Kelsey A.; Firmin, Ruth L.; Luther, Lauren; Goscha, Rick; Rapp, Charles A.; Holter, Mark C.; Psychology, School of ScienceObjective: The authors examined consumer outcomes before and after implementing CommonGround, a computer-based shared decision-making program. Methods: Consumers with severe mental illness (N=167) were interviewed prior to implementation and 12 and 18 months later to assess changes in active treatment involvement, symptoms, and recovery-related attitudes. Providers also rated consumers on level of treatment involvement. Results: Most consumers used CommonGround at least once (67%), but few used the program regularly. Mixed-effects regression analyses showed improvement in self-reported symptoms and recovery attitudes. Self-reported treatment involvement did not change; however, for a subset of consumers with the same providers over time (N=83), the providers rated consumers as more active in treatment. Conclusions: This study adds to the growing literature on tools to support shared decision making, showing the potential benefits of CommonGround for improving recovery outcomes. More work is needed to better engage consumers in CommonGround and to test the approach with more rigorous methods.Item Correlates of observer-rated active involvement in psychiatric treatment visits(Elsevier, 2017-10) Bonfils, Kelsey A.; Luther, Lauren; Fukui, Sadaaki; Adams, Erin L.; Dreison, Kimberly C.; Firmin, Ruth L.; Salyers, Michelle P.; Department of Psychology, School of ScienceAmong people with serious mental illness, increased patient activation has been linked to a range of key recovery outcomes. To date, patient activation has been measured largely through self-report. The present study investigated correlates of a new tool that assesses active involvement through rating audio-recordings of treatment visits. The key domains of patient activation assessed in visits included: patients asking questions, discussing with providers instances of being active in managing illness outside the session, talking about goals, bringing up concerns, making evaluative statements about treatment, setting the agenda for the visit, and making requests about the course of treatment. The new coding scheme proved to be a feasible and reliable method for identifying multi-faceted behavioral indicators of patient activation. Contrary to our hypotheses, in a sample of 166 people diagnosed with severe mental illnesses, self-reported activation and observer-rated indices of activation were often not correlated or correlated in unexpected directions with the new behavioral measure of patient activation. This suggests the nature of patient activation may be complex and work is needed to understand how observer-rated and self-rated activation may predict differential recovery outcomes.Item The "Critical" Elements of Illness Management and Recovery: Comparing Methodological Approaches(Springer, 2016-01) McGuire, Alan B.; Luther, Lauren; White, Dominique; White, Laura M.; McGrew, John H.; Salyers, Michelle P.; Department of Psychology, School of ScienceThis study examined three methodological approaches to defining the critical elements of Illness Management and Recovery (IMR), a curriculum-based approach to recovery. Sixty-seven IMR experts rated the criticality of 16 IMR elements on three dimensions: defining, essential, and impactful. Three elements (Recovery Orientation, Goal Setting and Follow-up, and IMR Curriculum) met all criteria for essential and defining and all but the most stringent criteria for impactful. Practitioners should consider competence in these areas as preeminent. The remaining 13 elements met varying criteria for essential and impactful. Findings suggest that criticality is a multifaceted construct, necessitating judgments about model elements across different criticality dimensions.Item The “Critical” Elements of Illness Management and Recovery: Comparing Methodological Approaches(Springer, 2016-01) McGuire, Alan B.; Luther, Lauren; White, Dominique; White, Laura M.; McGrew, John H.; Salyers, Michelle P.; Department of Psychology, School of ScienceThis study examined three methodological approaches to defining the critical elements of Illness Management and Recovery (IMR), a curriculum-based approach to recovery.
