We examined social problem solving in schizophrenia. Twenty-seven schizophrenic patients in an acute hospital, 19 patients with bipolar disease, and 17 demographically matched nonpatient controls were tested on an empirically developed problem-solving battery that assessed the ability to generate solutions to problems, the ability to evaluate the(More)
People with severe mental illness (SMI) have high rates of substance use disorders. The Transtheoretical Model (TTM) is a framework for understanding behavior change. There are five leading measures associated with the TTM - University of Rhode Island Change Assessment, Processes of Change Scale, Decisional Balance Scale, Abstinence Self-Efficacy Scale, and(More)
As part of an ongoing scale development process, this study provides an initial examination of the psychometric properties and validity of a new interview-based negative symptom instrument, the Clinical Assessment Interview for Negative Symptoms (CAINS), in outpatients with schizophrenia or schizoaffective disorder (N = 37). The scale was designed to(More)
This study examined (1) the relationships between electromyographic-measured nocturnal bruxism, self-reported stress, and several personality variables, and (2) the relationship between belief in a stress-bruxism relationship and self-reported stress. One hundred adult bruxers completed a battery of personality questionnaires, indicated whether they(More)
The Clinical Assessment Interview for Negative Symptoms (CAINS) is an empirically developed interview measure of negative symptoms. Building on prior work, this study examined the reliability and validity of a self-report measure based on the CAINS-the Motivation and Pleasure Scale-Self-Report (MAP-SR)-that assesses the motivation and pleasure domain of(More)
Negative symptoms have clear functional implications in schizophrenia and are typically unresponsive to current treatments. The cognitive model of negative symptoms suggests that dysfunctional beliefs are influential in the development and maintenance of negative symptoms and schizophrenia. The current study reports on a preliminary investigation of a new(More)
Though negative symptoms in schizophrenia are associated with a host of deleterious outcomes (e.g., White et al., 2009), not all individuals with schizophrenia suffer from negative symptoms (e.g., Blanchard et al., 2005). Thus, methods to quickly screen and identify patients for more intensive clinical interview assessments may have significant clinical and(More)
Negative symptoms like avolition and anhedonia are thought to involve difficulties with reward processing and motivation. The current study aimed to replicate and extend prior findings that individuals with schizophrenia display reduced willingness to expend effort for rewards and that such reduced effort is associated with negative symptoms, poor(More)
The development of a multimethod social problem-solving battery for schizophrenia is described. The battery is unique in that empirical methods were used throughout its development. The battery includes components that tap skills for response generation and response evaluation. The behavioral components of social problem solving are assessed in an extended(More)
Internalized stigma refers to the process by which individuals with mental illness apply negative stereotypes to themselves, expect to be rejected by others, and feel alienated from society. Though internalized stigma has been hypothesized to be associated with maladaptive cognitions and expectations of failure, this relationship with dysfunctional(More)
