Despite the existence of effective behavioral interventions for people diagnosed with serious mental illness (SMI), these continue to be underutilized. Barriers to implementation include a low frequency of staff-patient interactions, as well as a lack of knowledge about, and negative attitudes toward, behavioral interventions. Therefore, we examined the effects of a mandatory behavioral staff-training program on staff-patient interactions on a long-term psychiatric inpatient program for individuals with SMI.

The attentional impairments associated with schizophrenia are well-documented and profound. Psychopharmacological and most psychosocial interventions have been shown to have limited effect in improving attentional capacity. That said, one form of psychosocial treatment, attention shaping procedures (ASP), has been repeatedly demonstrated to produce significant and meaningful change in various aspects of participant attentiveness behaviors.

Objective: People with serious mental illnesses and co-occurring substance use disorders are often excluded from vocational services, despite the lack of evidence that having a substance use disorder prevents them from being able to work. This study explored enrollment in supported employment services among clients with and without co-occurring substance use disorders.

Methods: With data from electronic medical records from a psychiatric rehabilitation agency, relationships between co-occurring substance use disorders and supported employment were examined among 1,748 clients with serious mental illnesses who were consecutively admitted to the agency over a two-year period.

Objectives: Involvement of community mental health consumers in mental health decision making has been consistently associated with improvements in health outcomes. Electronic decision support systems (EDSSs) that support both consumer and provider decision making may be a sustainable way to improve dyadic communication in a field with approximately 50% workforce turnover per year. This study examined the feasibility of such a system and investigated proximal outcomes of the system's performance.

Recovery from schizophrenia has been conceptualized to involve not only symptom remission of symptoms and achievement of psychosocial milestones but also subjective changes in how persons appraise their lives and the extent to which they experience themselves as meaningful agents in the world. In this paper we review the potential of individual psychotherapy to address these more subjective aspects of recovery. Literature on the effectiveness of psychotherapy for persons with schizophrenia is discussed and two different paths by which psychotherapy might modify self-experience are described.

Cognitive impairment is prevalent in schizophrenia and is related to poorer functional and treatment outcomes. Cognitive assessment is therefore now a routine component of clinical trials of new treatments for schizophrenia. The current gold-standard for cognitive assessment in clinical trials for schizophrenia is the MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) Consensus Cognitive Battery (MCCB), which was developed based on expert consensus and incorporates paper-and-pencil tests (and one computerized measure) with an established history in the field of neuropsychology.

Self-stigma can undermine self-esteem and self-efficacy of people with serious mental illness. Coming out may be one way of handling self-stigma and it was expected that coming out would mediate the effects of self-stigma on quality of life. This study compares coming out to other approaches of controlling self-stigma.

Stigma may interfere with mental health service use. We measured self-stigma and stigma-related cognitions (group identification and perceived legitimacy of discrimination) at baseline in 85 people with schizophrenia, schizoaffective or affective disorders. After 6 months, 75 (88%) had reported use of mental health services.

Objective: This study provides preliminary evidence for the effectiveness of a residential program with comprehensive wrap-around services for pregnant and parenting foster care youth with severe mental illness or severe emotional disturbance who are preparing to transition to independent living.

Methods: Twenty-five females ages 18 to 21 participated. Program effectiveness was determined by tracking monthly status changes, such as education, employment, and hospitalizations, as well as by comparing scores on four bi-annually administered standardized assessments of parenting competency and stress, child maltreatment risk, and mental health symptoms.

Stigma can be a major stressor for individuals with schizophrenia and other mental illnesses. It is unclear, however, why some stigmatized individuals appraise stigma as more stressful, while others feel they can cope with the potential harm posed by public prejudice. We tested the hypothesis that the level of perceived public stigma and personal factors such as rejection sensitivity, perceived legitimacy of discrimination and ingroup perceptions (group value; group identification; entitativity, or the perception of the ingroup of people with mental illness as a coherent unit) predict the cognitive appraisal of stigma as a stressor.

Article Synopsis
  • Stigma significantly impacts individuals with schizophrenia and other mental illnesses, leading to emotional stress and cognitive coping responses, particularly when perceived harm from stigma exceeds coping resources.
  • A study involving 85 participants found that high stigma stress correlated with increased social anxiety and shame, which in turn lowered self-esteem and heightened feelings of hopelessness, though it did not affect social performance directly.
  • Understanding the interplay between stigma stress, emotional responses, and coping mechanisms can inform interventions aimed at mitigating the negative effects of stigma on mental health outcomes.

Thresholds Rehabilitation Centers is one of the largest providers of psychiatric rehabilitation services in the United States, and the Dartmouth Psychiatric Research Center is a highly regarded team of rehabilitation researchers. This column describes efforts to build upon the long-standing collaborative relationship between Thresholds (community partner) and Dartmouth (academic partner) to implement and study shared decision making in a community mental health care setting that serves an ethnoracially diverse population. Shared decision making encompasses a client-centered approach in which client and practitioner are equal partners.

Introduction: In a previous study (Silverstein, Bakshi, Chapman, & Nowlis, 1998a, Cognitive Neuropsychiatry) we demonstrated that while schizophrenia patients showed similar learning curves as nonpatient controls when determining whether a configural pattern of elements has been seen before or not, they did not demonstrate any learning curve with nonconfigural stimuli (in contrast to controls). Methodological limitations of that study, however, precluded generalisability of those effects.

Methods: In the present study, therefore, different groups of schizophrenia patients (n = 18) and controls (n = 22) were administered a modified version of the familiarity judgement task used in Silverstein et al.

Introduction: Chronic schizophrenia patients have previously demonstrated performance deficits in contour integration tasks. The purpose of this study was to investigate whether schizophrenia patients, spanning a range of illness severity, would demonstrate responsiveness to manipulations that recruit top-down processing strategies involving learning and sequencing effects in a contour integration task.

Methods: We administered a contour integration test over four consecutive days and in two different presentation conditions each day.

Background: Several small-N, uncontrolled reports have demonstrated that the behavioral technique of attention shaping has significantly increased attention span among severely ill schizophrenia patients.

Method: In this study, we evaluated the effectiveness of using an individually administered intervention for improving sustained attention, Attention Process Training (APT), followed by an attention-shaping procedure within the context of an ongoing skills training group. Patients were randomly assigned to receive either the APT and attention-shaping sequence (n = 18) or equivalent hours of treatment in the same intensive behavioral rehabilitation program (n = 13).

Cognitive rehabilitation is becoming an increasingly popular intervention in treatment programs for people with schizophrenia. Despite this increased acceptance, however, the evidence base on its effectiveness is not impressive. Moreover, given the evidence of cognitive recovery in treated patients who do not receive cognitive rehabilitation--from newer medications and from other evidence-based psychosocial interventions--it is not clear whether cognitive rehabilitation is worth its expense in time and resources.

While many effective group-based psychiatric rehabilitation interventions now exist, many severely disabled patients are unable to benefit from them due to a reduced ability to pay attention in group sessions. Moreover, inattentiveness can be due to one or more of multiple factors, including a sustained attention deficit, poor motivation, sedating side effects of medication, and the interfering effects of hallucinations and disturbing thoughts. Existing cognitive rehabilitation interventions for schizophrenia typically do not address these factors, instead targeting higher level functions such as memory, learning, problem-solving, and executive functioning.

There now exist a number of milieu-based and group-based behavioral treatments that have demonstrated effectiveness with so-called "treatment-refractory" schizophrenia patients. These interventions are not likely to achieve their maximal impact, however, unless program staff consistently employ behavioral principles in their moment-to-moment interactions with patients throughout the day. In this paper we describe a number of interpersonal techniques that are effective in dealing with a variety of institutionalized/dependent and provocative/aggressive behaviors.
