In this study, we explored two areas of social cognition not previously investigated early in the course of psychosis.

Thus, methods to quickly screen and identify patients for more intensive clinical interview assessments may have significant clinical and research utility. The present study is a preliminary examination of the reliability and validity of a self-report version of the newly developed Clinical Assessment Interview for Negative Symptoms (CAINS; Blanchard et al., 2011; Forbes et al., 2010; Horan et al., 2011). The CAINS-SR is a 30-item self-report measure that assesses Experiential (avolition, anhedonia, asociality) and Expressive (blunted affect, alogia) domains of negative symptoms. Participants (N = 69) completed the CAINS-SR questionnaire and were evaluated with symptom interviews using the CAINS and other non-negative symptom interviews that assessed psychotic, aff...

Although social anhedonia is defined as an affective construct (less pleasure derived from social encounters), little is known about the emotional responsivity and expressivity of individuals with high levels of social anhedonia. After screening a large sample of female undergraduate students (N = 1 085), a cohort of psychometrically identified individuals with high levels of social anhedonia (n = 34) and normally hedonic controls (n = 45) participated in laboratory assessments involving trait affectivity, self-reported dispositional emotional expressiveness, and the expression and experience of emotion in response to neutral, nonaffiliative (i.e., comedy) and affiliative film clips. Results revealed that individuals with high levels of social anhedonia are characterized by lower positive affect, both as a trait and in response to emotionally evocative stimuli, and are less facially expressive, both by their own self-report and in response to film clips. Attenuated positive affect was observed across film stimuli, indicating a general reduction in affective response rather than a specific decrease in responsivity for affiliative stimuli. Future work should continue to investigate whether there is a unique role for social stimuli in the emotional lives of individuals with high levels of social anhedonia or whether these individuals tend to experience anhedonia more broadly regardless of social context.

Although marked impairments in social cognition have been documented in both groups, little empirical work has compared the social cognitive functioning of these two clinical groups.

It is unknown if social anhedonia is associated with true deficits in experiential reactions or if lower social functioning in social anhedonia reflects behavioral deficits in social skill or initiation of social contact. Using a novel social interaction task, the current study compared controls (n ¼ 60) to individuals elevated on social anhedonia (n ¼49) on observer-rated social skill and facial affect and participant self-reports of their experiential reactions to an affiliative interaction. Compared to the control group, the social anhedonia group was rated as behaviorally less affiliative and less socially skilled during the affiliative interaction. In response to the social interaction, the social anhedonia group reported less change in positive affect, less willingness to engage in future social interactions with the interaction partner, and less positive reactions toward the interaction partner compared to controls. There were no group differences in facial displays of emotion. Using a standardized affiliative stimulus, it was demonstrated that individuals high in social anhedonia have alterations in both their social skill and in their self-reported experiential reactions during a social interaction.

Both autism and schizophrenia feature impairments in aspects of social cognition that may be related to amygdala dysfunction, but the exact nature and specificity of these impairments remain unclear.

Assessment of clinical symptoms and social functioning were conducted at baseline, and alliance ratings were obtained at 5 weeks. The Working Alliance Inventory had high internal consistency, but there were low correlations between client and therapist ratings. Results also indicated that social functioning and the activation and autistic preoccupation factors on the Positive and Negative Syndrome Scale were significant predictors of therapists' alliance ratings. There were no significant relationships between clinical predictors and clients' therapeutic alliance ratings. The findings indicate that client interpersonal factors are significant predictors of the therapist-rated alliance in the treatment of schizophrenia. Low correlations between clients' and therapists' ratings of the alliance should be examined in future research.

Participants from the agency Compeer (which pairs volunteers with people with SMI) were compared to volunteers from a control agency and to nonvolunteer participants from the community on stigma measures over a 6-month period. The quality of the relationship between the Compeer volunteer and consumer and its association with changes in stigmatizing attitudes was also assessed. The results provide preliminary evidence that naturalistic contact can reduce negative affective responses to individuals with SMI. Furthermore, changes in affective response were related to the quality of the contact between the Compeer volunteer and consumer. Implications for future research are discussed.

Studies of this 'broad autism phenotype' (BAP) may provide a potentially important, complementary approach for detecting the genes causing autism and defining associated neural circuitry, by identifying more refined phenotypes which can be measured quantitatively in both affected and unaffected individuals, and which are tied to functioning in particular regions of the brain.

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 negative symptoms. Thirtyseven participants with schizophrenia or schizoaffective disorder completed the 18-item MAP-SR, the CAINS, and other measures of functional outcome. Item analyses revealed three items that performed poorly. The revised 15-item MAP-SR demonstrated good internal consistency and convergent validity with the clinician-rated Motivation and Pleasure scale of the CAINS, as well as good discriminant validity, with little association with psychotic symptoms or depression/anxiety. MAP-SR scores were related to social anhedonia, social closeness, and clinician-rated social functioning. The MAP-SR is a promising self-report measure of severity of negative symptoms.
