Objective While recent studies have found deficits in theory of mind (ToM) skills in individuals at ultra-high risk (UHR) for psychosis, empathic tendencies in these subjects remain unclear. The presence of high schizotypy and compromised executive functions, which are found in UHR individuals, would affect ToM skills and empathic tendencies. We investigated the ToM skills and empathic tendencies of UHR individuals and examined their relationship with schizotypy and executive function.Methods This study included 28 UHR individuals and 28 age- and sex-matched healthy controls. All participants completed a self-reported empathic scale (Interpersonal Reactivity Index) and the Wisconsin Schizotypy Scales. Additionally, the ToM Picture Stories Task and Wisconsin Card Sorting Test were conducted.Results UHR individuals showed a trend toward lower self-reported empathic tendencies; however, there were no differences in ToM skills between the two groups. Of the four subscales of the IRI, only empathic concern showed a significant difference between the two groups. Empathic concern was inversely associated with negative schizotypy.Conclusion Our findings suggest that UHR individuals show relatively preserved cognitive empathy but compromised emotional empathy. Furthermore, in UHR individuals, the empathic concern subscale of the IRI was associated with negative schizotypy, while ToM skills were related to positive schizotypy and executive function.

“…28,[33][34][35][36] To our knowledge, only one study has evaluated trait positive and negative affect in individuals at CHR for psychosis. Seo and colleagues 37 found that individuals at CHR reported lower levels of trait positive and higher levels of trait negative affect. Moreover, only negative symptoms predicted individual differences in both higher negative and lower positive trait affect.…”

“…These findings add important specificity for studies showing links between emotions and negative symptoms. 5,37 The breadth of interconnectedness between trait emotion, symptoms and functioning highlights not only the generalised pathology of emotion abnormalities in the population at CHR for psychosis, but also the importance of making emotions the target of interventions for improving functional outcomes.…”

Trait emotional experience in individuals with schizophrenia and youth at clinical high risk for psychosis

Background Disturbances in trait emotions are a predominant feature in schizophrenia. However, less is known about (a) differences in trait emotion across phases of the illness such as the clinical high-risk (CHR) phase and (b) whether abnormalities in trait emotion that are associated with negative symptoms are driven by primary (i.e. idiopathic) or secondary (e.g. depression, anxiety) factors. Aims To examine profiles of trait affective disturbance and their clinical correlates in individuals with schizophrenia and individuals at CHR for psychosis. Method In two studies (sample 1: 56 out-patients diagnosed with schizophrenia and 34 demographically matched individuals without schizophrenia (controls); sample 2: 50 individuals at CHR and 56 individuals not at CHR (controls)), participants completed self-report trait positive affect and negative affect questionnaires, clinical symptom interviews (positive, negative, disorganised, depression, anxiety) and community-based functional outcome measures. Results Both clinical groups reported lower levels of positive affect (specific to joy among individuals with schizophrenia) and higher levels of negative affect compared with controls. For individuals with schizophrenia, links were found between positive affect and negative symptoms (which remained after controlling for secondary factors) and between negative affect and positive symptoms. For individuals at CHR, links were found between both affect dimensions and both types of symptom (which were largely accounted for by secondary factors). Conclusions Both clinical groups showed some evidence of reduced trait positive affect and elevated trait negative affect, suggesting that increasing trait positive affect and reducing trait negative affect is an important treatment goal across both populations. Clinical correlates of these emotional abnormalities were more integrally linked to clinical symptoms in individuals with schizophrenia and more closely linked to secondary influences such as depression and anxiety in individuals at CHR. Declaration of interest None.

Aim: Youth at clinical high risk for psychosis often demonstrate significant negative symptoms and poor functioning. However, the magnitude and direction of the relationship between the two remains unknown. Therefore, the objective of this systematic review was to summarize the relationship between negative symptoms and functioning in CHR samples.Method: Electronic databases Embase, EBM, MEDLINE, CINAHL, and PsycINFO were searched from inception. Studies were selected if they included any study that reported a relationship between negative symptoms and functioning in youth at CHR. The correlation coefficient r was converted to Cohen's d and all random effects meta-analyses were performed using the transformed values.Results: Forty-one studies met the inclusion criteria, including a total of 4,574 clinical high risk for psychosis individuals. Negative symptom total scores were significantly associated with poorer global functioning (d, −1.40; 95% CI= −1.82, −0.98; I 2 =79.4%; P<0.001, 9 studies, N=782), social functioning (d, −1.10; 95% CI= −1.27, −0.93; I 2 =10.40%; P<0.001, 12 studies, N=811), and role functioning (d, −0.96; 95% CI= −1.17, −0.76; I 2 =41.1%; P<0.001, 9 studies, N=881).In addition, negative symptoms were consistently associated with poor premorbid functioning. When examining negative symptom domains; avolition, anhedonia, and blunted affect were each significantly and independently associated with poorer social functioning and role functioning. In terms of prediction models, negative symptoms contributed to the prediction of lower functioning across multiple studies. Conclusion:This meta-analysis demonstrated a consistent and strong relationship between negative symptoms and functioning in youth at clinical high risk for psychosis.
