Impairments in willingness to exert effort contribute the motivational deficits characteristic of negative symptoms schizophrenia. The current study evaluated psychometric properties 5 new or adapted paradigms determine their suitability for use clinical trials This included 94 clinically stable participants with schizophrenia and 40 healthy controls. effort-based decision-making battery was administered twice group (baseline, 4-week retest) once control group. 1 that assesses cognitive...
Social disability is a defining characteristic of schizophrenia and substantial public health problem. It has several components that are difficult to disentangle. One component, social disconnection, occurs extensively in the general community among nonhelp-seeking individuals. disconnection an objective, long-standing lack social/family relationships minimal participation activities. associated with negative effects, including early mortality, distinct from subjective loneliness. These 2...
Effort-based decision making has strong conceptual links to the motivational disturbances that define a key subdomain of negative symptoms. However, extent which effort-based decision-making performance relates symptoms, and other clinical functionally important variables yet be systematically investigated. In 94 clinically stable outpatients with schizophrenia, we examined external validity 5 paradigms, including Effort Expenditure for Rewards, Balloon Effort, Grip Strength Deck Choice...
Although individuals with schizophrenia show impaired feedback-driven learning on probabilistic reversal (PRL) tasks, the specific factors that contribute to these deficits remain unknown. Recent work has suggested several potential causes including neurocognitive impairments, clinical symptoms, and types of feedback-related errors. To examine this issue, we administered a PRL task 126 stable outpatients 72 matched controls, patients were retested 4 weeks later. The involved an initial...
People with schizophrenia on average are more socially isolated, lonelier, have social cognitive impairment, and less motivated than healthy individuals. bipolar disorder also isolation, though typically that seen in schizophrenia. We aimed to disentangle whether the motivation impairments observed a specific feature of clinical condition
Schizophrenia is associated with amotivation and reduced goal-directed behavior, which have been linked to poor functional outcomes. Motivational deficits in schizophrenia are often measured using effort-based decision-making (EBDM) paradigms, revealing consistent alterations effort expenditure relative controls. Although these results generally interpreted terms of decreased motivation, the ability use trial-by-trial changes reward magnitude or probability receipt guide allocation may also...
Effort-based decision-making paradigms are increasingly utilized to gain insight into the nature of motivation deficits. Research has shown associations between effort-based decision making and experiential negative symptoms; however, not consistent. The current study had two primary goals. First, we aimed replicate previous findings a deficit in among individuals with schizophrenia on test cognitive effort. Second, large sample combined from study, sought examine association symptoms effort...
Negative symptoms are a primary cause of disability in schizophrenia for which there no established pharmacotherapies. This study evaluated novel psychosocial intervention that combined two evidence-based practices-motivational interviewing and cognitive-behavioral therapy (MI-CBT)-for the treatment motivational negative symptoms.Seventy-nine participants with moderate to severe were included randomized controlled trial comparing 12-session MI-CBT mindfulness control condition. Participants...
Limited previous literature on peers influenced by students with problems of professional competence has descriptively focused rates peer identification and actions in response to identification. Prior research suggested that who exhibit diminished functioning due life stressors or psychological distress may be qualitatively different than lack the capacity ever perform duties a competent psychologist. Thus, current study explored perceptions various graduate psychology might experience. A...
Measurement of program climate, defined as a sense environmental safety amid respectful relationships and effective organizational systems, has been associated with myriad important outcomes in school workplace settings. However, climate received scant attention the realm graduate training, including training psychology health service programs, despite related research suggesting that quality mentor–mentee environment influences student satisfaction educational attainment. The current study...
Unemployment is a primary functional deficit for the majority of adults with schizophrenia. Research indicates that over two-thirds living in community schizophrenia are unemployed. Despite effective programs to assist job identification and placement, ability attain maintain employment remains pressing concern. Neurocognitive functioning widely acknowledged be determinant work outcome; however, effect sizes tend small medium range. The present study sought further understand determinants...
Abstract Social disconnection, including objective social isolation and subjective loneliness, is linked to substantial health risks. Yet, little known about the predictors of disconnection in individuals with mental illness. Here, we used machine learning identify loneliness schizophrenia ( N = 72), a psychiatric condition associated disconnection. For comparison, also included two other groups: comparison sample bipolar disorder 48) community enriched for 151). We fitted statistical models...
