    Measuring participation in an evidence-based practice: Illness management and recovery group attendance
    (Elsevier, 2013-12-30) McGuire, Alan B.; Bonfils, Kelsey A.; Kukla, Marina; Myers, Laura; Salyers, Michelle P.; Department of Psychology, School of Science
    Given the important role of treatment attendance as an indicator of program implementation and as a potential moderator of program effectiveness, this study sought to develop useful indicators of attendance for evidence-based practices. The current study examined consumer attendance patterns in a randomized controlled trial comparing illness management and recovery (n = 60) to a problem solving control condition (n = 58). Associations were examined between consumer clinical indicators, demographics, and level of recovery and indices of attendance. Attendance was poor, but comparable to rates found in many other studies. Four indicators of attendance (percent sessions attended, time enrolled, periods of attendance, and longest period of attendance) were highly inter-related and were more sensitive to baseline differences than a traditional approach of dichotomizing participants into “attenders” and “non-attenders.” Older age, lower hostility, fewer psychotic symptoms, and more education were associated with higher group attendance in both treatment conditions; the client-reported illness management and recovery scale was associated with attendance in the control group. Indicators of attendance were an advancement over dichotomous classification. Strategies to increase attendance are still needed, particularly for younger consumers with greater positive symptoms.

    Metacognitive capacities for reflection in schizophrenia: implications for developing treatments
    (Oxford University Press, 2014-05) Lysaker, Paul H.; Dimaggio, Giancarlo; Department of Psychiatry, IU School of Medicine
    Models of schizophrenia, which focus exclusively on discrete symptoms and neurocognitive deficits, risk missing the possibility that a core feature of the disorder involves a reduced capacity to construct complex and integrated representations of self and others. This column details a new methodology that has been used to assess deficits in the metacognitive abilities that allow persons to form complex ideas about themselves and others and to use that knowledge to respond to psychosocial challenges in schizophrenia. Evidence is summarized supporting the reliability and validity of this method, as well as links this work has revealed between metacognition and psychosocial outcomes. It is suggested that this work points to the need to develop interventions which move beyond addressing symptoms and specific skills, and assist persons to recapture lost or atrophied metacognitive capacity and so form the kind of ideas about themselves and others needed, to move meaningfully toward recovery.

    Nicotine is more addictive, not more cognitively therapeutic in a neurodevelopmental model of schizophrenia produced by neonatal ventral hippocampal lesions
    (Wiley Blackwell (Blackwell Publishing), 2014-11) Berg, Sarah A.; Sentir, Alena M.; Cooley, Benjamin S.; Engleman, Eric A.; Chambers, R. Andrew; Department of Psychiatry, IU School of Medicine
    Nicotine dependence is the leading cause of death in the United States. However, research on high rates of nicotine use in mental illness has primarily explained this co-morbidity as reflecting nicotine's therapeutic benefits, especially for cognitive symptoms, equating smoking with 'self-medication'. We used a leading neurodevelopmental model of mental illness in rats to prospectively test the alternative possibility that nicotine dependence pervades mental illness because nicotine is simply more addictive in mentally ill brains that involve developmental hippocampal dysfunction. Neonatal ventral hippocampal lesions (NVHL) have previously been demonstrated to produce post-adolescent-onset, pharmacological, neurobiological and cognitive-deficit features of schizophrenia. Here, we show that NVHLs increase adult nicotine self-administration, potentiating acquisition-intake, total nicotine consumed and drug seeking. Behavioral sensitization to nicotine in adolescence prior to self-administration is not accentuated by NVHLs in contrast to increased nicotine self-administration and behavioral sensitization documented in adult NVHL rats, suggesting periadolescent neurodevelopmental onset of nicotine addiction vulnerability in the NVHL model. Delivering a nicotine regimen approximating the exposure used in the sensitization and self-administration experiments (i.e. as a treatment) to adult rats did not specifically reverse NVHL-induced cortical-hippocampal-dependent cognitive deficits and actually worsened cognitive efficiency after nicotine treatment stopped, generating deficits that resemble those due to NVHLs. These findings represent the first prospective evidence demonstrating a causal link between disease processes in schizophrenia and nicotine addiction. Developmental cortical-temporal limbic dysfunction in mental illness may thus amplify nicotine's reinforcing effects and addiction risk and severity, even while producing cognitive deficits that are not specifically or substantially reversible with nicotine.

    Self-disturbances in schizophrenia: history, phenomenology, and relevant findings from research on metacognition
    (Oxford University Press, 2014-01) Mishara, Aaron L.; Lysaker, Paul H.; Schwartz, Michael A.; Department of Psychiatry, IU School of Medicine
    With a tradition of examining self-disturbances (Ichstörungen) in schizophrenia, phenomenological psychiatry studies the person's subjective experience without imposing theoretical agenda on what is reported. Although this tradition offers promising interface with current neurobiological models of schizophrenia, both the concept of Ichstörung and its history are not well understood. In this article, we discuss the meaning of Ichstörung, the role it played in the development of the concept of schizophrenia, and recent research on metacognition that allows for the quantitative study of the link between self-disturbance and outcome in schizophrenia. Phenomenological psychiatrists such as Blankenburg, Binswanger, and Conrad interpreted the Ichstörung as disturbed relationship to self and others, thus challenging recent efforts to interpret self-disturbance as diminished pure passive self-affection, which putatively "explains" schizophrenia and its various symptoms. Narrative is a reflective, embodied process, which requires a dynamic shifting of perspectives which, when compromised, may reflect disrupted binding of the components of self-experience. The Metacognition Assessment Scale-abbreviated as MAS-A-suggests that persons with schizophrenia tend to produce narratives with reductions in the binding processes required to produce an integrated, embodied self within narrated life stories, and in interactive relationships with others.
