Social skills, negative symptoms and real-world functioning in individuals at ultra-high risk of psychosis.

Impairment in real-world social functioning is observed in individuals at Ultra-High Risk (UHR) of psychosis. Both social skills and negative symptoms appear to influence real-world functioning. This study aims to examine the psychometric properties of a social skills measure, the High-Risk Social Challenge task (HiSoC), and evaluate the relationship between social skills, negative symptoms, and real-world functioning in UHR individuals. HiSoC data was analysed in 87 UHR individuals and 358 healthy controls. Exploratory factor analysis (EFA) was used to evaluate the factor structure of the HiSoC task. Convergent and divergent validity were assessed. Negative symptoms were assessed on the Positive and Negative Syndrome Scale (PANSS) and real-world functioning was indexed by the Global Assessment of Functioning (GAF). Commonality analysis was used to partition unique and shared variance of HiSoC and negative symptoms with real-world functioning. EFA yielded a three-factor structure of HiSoC consisting of Affect, Odd behaviour and language, and Social-interpersonal. The HiSoC task discriminated UHR and healthy controls (p<0.001, Cohen's d=0.437-0.598). Commonality analysis revealed that the unique variance of the social amotivation subdomain of negative symptoms was the strongest predictor of GAF (p<.001, R2 =.480). Shared variance of 3.7% between HiSoC Social-interpersonal and social amotivation was observed in relation to functioning. The HiSoC is a psychometrically valid task that is sensitive to identify social skill deficits in UHR. While social skills are related to functioning, experiential negative symptoms appear to be an important target for improving real-world functional outcomes.

The impact of a mother-infant intervention on parenting and infant response to challenge: A pilot randomized controlled trial with adolescent mothers in El Salvador.

A pilot randomized controlled trial (RCT) was conducted in El Salvador of an intervention ('Thula Sana') previously shown to enhance maternal sensitivity and infant security of attachment in a South African sample. In El Salvador, trained community workers delivered the intervention from late pregnancy to 6 months postpartum as part of a home-visiting programme. The sample comprised 64 pregnant adolescent women, aged 14-19 years, living in predominantly rural settings. They were randomised to receive either the intervention or normal care. Demographic information was collected at baseline and, immediately post-intervention, blind assessments were made of parental sensitivity and infant emotion regulation. The intervention was found to have a substantial positive impact on maternal sensitivity. Further, compared to control group, infants in the intervention group showed more regulated behaviour: in a social challenge task they showed more attempts to restore communication, and in a non-social challenge task they showed more social and goal-directed behaviour. This replication and extension of the South African findings in a small El Salvador sample shows promise and justifies the conduct of a large-scale RCT in a Central or South American context.

Assessing social skills in individuals at ultra-high risk for psychosis: Validation of the High Risk Social Challenge task (HiSoC)

BackgroundIndividuals at ultra-high risk (UHR) for psychosis exhibit deficits in social functioning that may relate to efficacy of social skills performance. There is, though, a scarcity of objective measures assessing social skills performance in the UHR state. This study assessed the psychometric properties of a relatively new social skills measure, the High Risk Social Challenge Task (HiSoC), in an UHR population. MethodsExploratory factor analysis was used to assess the factor structure of the HiSoC task in 102 UHR individuals and 66 healthy controls (HC). Convergent and discriminant validity of the HiSoC was assessed. ResultsOur findings revealed a three-factor structure comprising the factors “Affect”, “Odd Behaviour and Language”, and “Social-Interpersonal”. The test showed excellent inter-rater reliability (ICC between 0.88 and 0.98). The HiSoC correlated significantly, as expected, with measures of global and social functioning demonstrating construct validity and utility as a social skills assessment tool in the UHR population. The HiSoC task discriminated between UHR and HC with large effect sizes (Cohen's d range=1.40–1.94). DiscussionOur findings provide evidence for a three-factor structure of the HiSoC task corresponding to the original American version of the task. Additionally, our findings reveal the HiSoC to be sensitive to social skills impairments in the UHR population and suggest it to be a suitable screening tool for social skills deficits in UHR states. The robust correlations with real-life functioning indicate social skills to be an important target for assessment and intervention within the UHR population.

An exploratory analysis of the joint contribution of HPA axis activation and motivation to early adolescent depressive symptoms.

This study examines the interactive contribution of the hypothalamic-pituitary-adrenal (HPA) axis and approach-avoidance motivation systems to longitudinal changes in depressive symptoms across the adolescent transition. In the summer prior to, or fall of, 4th grade, 132 youth (68 girls; 64 boys; M age = 9.46 years) participated in a social challenge task and reported on their depressive symptoms. In the winter of 6th grade, youth completed a semi-structured interview of depression and a self-report measure of approach-avoidance motivations. Analyses revealed two profiles of risk for adolescent depressive symptoms, with some gender differences: (1) excessive disengagement, reflected in HPA underactivation along with low approach motivation or high avoidance motivation; and (2) excessive engagement, reflected in HPA overactivation along with high approach motivation. This research highlights the importance of a multi-system perspective on development, suggesting that the implications of HPA dysregulation for depressive symptoms are contingent on adolescents' tendencies toward approach versus avoidance.

Negative symptoms mediate the relationship between neurocognition and function in individuals at ultrahigh risk for psychosis.

Neurocognition is known to impact functioning in individuals at ultrahigh risk (UHR) for psychosis, but studies investigating potential mediators of this relationship are scarce. Building on evidence from schizophrenia spectrum disorders, the study tested whether negative symptoms and social skills act as mediators between neurocognition and functional outcome in UHR individuals. Ultrahigh risk participants (N = 84) underwent neurocognitive testing using the Brief Assessment of Cognition in Schizophrenia. Social skills and negative symptoms were assessed using the High-Risk Social Challenge task and the Scale for the Assessment of Negative Symptoms respectively. Four instruments were used to assess overall functioning, and one instrument assessed quality of life encompassing social functioning. The cross-sectional analyses revealed that neurocognition was related to the measures of functioning. Negative symptoms mediated the relationship between neurocognition and four of the five measures of functioning. We did not find social skills to mediate between neurocognition and functioning. Negative symptoms appear to mediate the relationship between neurocognition and functional outcome in UHR individuals, but the finding needs to be confirmed and extended to longitudinal studies. This underscores the importance of focusing on both neurocognition and negative symptoms when aiming at improving the functional outcome of UHR individuals.

Infant respiratory sinus arrhythmia and maternal depressive symptoms predict toddler sleep problems.

This study examined the direct and interactive effects of infants' respiratory sinus arrhythmia (RSA) and maternal depressive symptoms (MDS) during the first 6 months of life in the prediction of children's sleep problems at age 18 months. Participants included 156 children and their mothers who were followed from 3 to 18 months of age. At ages 3 and 6 months, infants' cardiac activity was recorded at rest and during the still-face paradigm, a mother-child social challenge task, and estimates of infant baseline RSA (RSAB) and RSA withdrawal (RSAW) were calculated. Mothers reported about their depressive symptoms at 3, 6, and 18 months, and about infants' sleep problems at age 18 months. Less RSAW and higher levels of MDS predicted more sleep problems at age 18 months. Additionally, RSAB moderated the link between MDS and children's sleep problems such that MDS were related to more sleep problems only for infants with high levels of RSAB. Results illustrate the importance of RSA as both a direct predictor and a moderator of maternal influences in the prediction of early sleep problems.

Contributions of socialisation of coping to physiological responses to stress

The messages mothers communicate to their children about coping may play an important role in children's emotional development by shaping children's responses to stress. Building on prior research demonstrating associations between maternal socialisation of coping (SOC) and children's self‐reported coping and emotional functioning, we examined the contribution of SOC to children's physiological responses to stress. Mothers completed a measure of SOC with peer victimisation. Children (N = 118; M age = 9.46 years, SD = .33) completed a measure of peer victimisation and participated in a laboratory social challenge task. Saliva samples were collected prior to and following the task and were assayed for alpha‐amylase (sAA), a marker of autonomic nervous system (ANS) activation. Hierarchical linear modelling analyses revealed that SOC contributed to sAA reactivity. Peer victimisation predicted greater sAA reactivity when mothers made few engagement suggestions (orienting towards stress and associated emotions and cognitions) but not when mothers made many engagement suggestions. Mothers' distress responses predicted greater sAA reactivity. These findings provide novel evidence that the messages parents communicate about coping have implications for children's physiological reactivity to stress during middle childhood.

Individual differences in biological stress responses moderate the contribution of early peer victimization to subsequent depressive symptoms.

Some children who are exposed to early peer victimization become depressed, whereas others are resilient. Understanding individual differences in responses to early adversity, such as victimization, is critical for developing both comprehensive theoretical models and effective interventions. This study examined whether individual differences in biological stress responses (i.e., activation of the hypothalamic-pituitary-adrenal axis and autonomic nervous system) moderated the contribution of peer victimization to depressive symptoms across a 1-year period. Children (N = 132; M age = 9.46 years, SD = 0.33) completed measures of peer victimization and depressive symptoms, and rated their ruminative responses (i.e., persistent thoughts about negative task-related emotion and experiences) to a laboratory-based social challenge task involving two conflict-of-interests situations with an unfamiliar peer. Children's saliva was collected prior to, and following, participation in the task, and was later assayed for cortisol and alpha amylase [sAA]. Victimization interacted with levels of cortisol measured in anticipation of the task to predict task-related rumination and depressive symptoms 1 year later, adjusting for initial symptoms. Specifically, victimization served as a risk factor for rumination and depressive symptoms in children with heightened but not dampened anticipatory cortisol; yet, heightened anticipatory cortisol was protective against rumination and depressive symptoms in low-victimized children. Victimization also predicted subsequent depressive symptoms in girls with high sAA reactivity across the task. This study advances contemporary theory and research by implicating individual variation in biological stress responses as one determinant of sensitivity to the mental health effects of early adversity.

Peer Victimization and Aggression: Moderation by Individual Differences in Salivary Cortiol and Alpha-Amylase

This research examined whether variations in salivary measures of the hypothalamic-pituitary-adrenal axis (cortisol) and autonomic nervous system (alpha amylase [sAA]) contribute to individual differences in the association between peer victimization and aggression. Children (N = 132; M age = 9.46 years, SD = 0.33) completed a measure of peer victimization, teachers rated children's aggression, and children's saliva was collected prior to, and following, participation in a laboratory-based peer-oriented social challenge task. Children rated their level of frustration at the end of the task. Results revealed that victimization interacted with cortisol and sAA measured in anticipation of the task to predict aggression; the victimization x cortisol contribution to aggression was partly mediated by children's self-reported frustration level. Victimization also was associated with heightened frustration in girls with high task-related sAA reactivity. Task-related sAA reactivity was associated with heightened aggression, but only for girls. These findings suggest that associations between peer victimization and aggression are moderated by variation in the activity of the major components of the psychobiology of stress; results are discussed in relation to theoretical models of individual differences in biological sensitivity to context.

Dimensions of Impulsivity Are Associated with Poor Spatial Working Memory Performance in Monkeys

Impulsive behavior and novelty seeking are dimensions of temperament that are behavioral determinants of risk for attention deficit/hyperactivity disorder and its neurocognitive endophenotypes, and variation in the dopamine D4 receptor gene (DRD4) explains at least a portion of the variance in the traits. To further characterize the dimensional phenotype associated with impulsiveness, adolescent male monkeys were evaluated using ecologically valid tests of impulsive approach and aggression in response to social or nonsocial stimuli; subsequently, a delayed response task was implemented to assess spatial working memory performance. Subjects were selected into this study based on their response to the social challenge task or by DRD4 genotype, resulting in three groups: low-impulsivity/common DRD4 allele, high-impulsivity/common DRD4 allele, or rare DRD4 allele. All animals acquired the delayed response task and could perform at near ceiling levels when a approximately 0 s delay version was imposed, but as delays were lengthened, high-impulsive animals, regardless of DRD4 genotype, made fewer correct responses than did low-impulsive subjects; an inverse relationship existed for working memory and impulsivity. Notably, impulsive behavior evoked by social and nonsocial stimuli explained overlapping and independent portions of the variance in working memory performance. CSF levels of monoamine metabolites did not significantly differentiate the high- and low-impulsive animals, although monkeys carrying the DRD4 rare allele tended to exhibit higher monoamine turnover. These data indicate that dimensions of impulsivity may impact on working memory performance in qualitatively similar ways but through different mechanisms.

Social behavior and cortisol reactivity in children with fragile X syndrome

To examine the association between limbic-hypothalamic-pituitary-adrenal (L-HPA) axis reactivity and social behavior in children with fragile X syndrome (FXS). Salivary cortisol changes and concurrent anxiety-related behaviors consistent with the behavioral phenotype of FXS were measured in 90 children with the fragile X full mutation and their 90 unaffected siblings during a social challenge task in the home. Boys and girls with FXS demonstrated more gaze aversion, task avoidance, behavioral signs of distress, and poorer vocal quality than the unaffected siblings. Multiple regression analyses showed that after accounting for effects of IQ, gender, age, quality of the home environment, and basal cortisol level, cortisol reactivity to the task was significantly associated with social gaze in children with FXS. The most gaze-aversive children with FXS had cortisol reductions, whereas those with more eye contact demonstrated the most cortisol reactivity. Unaffected siblings demonstrated an opposite pattern in which less eye contact was associated with increased cortisol reactivity. Results of the study suggest a unique relation between abnormal gaze behavior and L-HPA mediated stress reactivity in FXS.

Cortisol and behavior in fragile X syndrome

The purpose of this study was to determine if children with fragile X syndrome, who typically demonstrate a neurobehavioral phenotype that includes social anxiety, withdrawal, and hyper-arousal, have increased levels of cortisol, a hormone associated with stress. The relevance of adrenocortical activity to the fragile X phenotype also was examined. One hundred and nine children with the fragile X full mutation (70 males and 39 females) and their unaffected siblings (51 males and 58 females) completed an in-home evaluation including a cognitive assessment and a structured social challenge task. Multiple samples of salivary cortisol were collected throughout the evaluation day and on two typical non-school days. Measures of the fragile X mental retardation (FMR1) gene, child intelligence, the quality of the home environment, parental psychopathology, and the effectiveness of educational and therapeutic services also were collected. Linear mixed-effects analyses were used to examine differences in cortisol associated with the fragile X diagnosis and gender (fixed effects) and to estimate individual subject and familial variation (random effects) in cortisol hormone levels. Hierarchical multiple regression analyses were conducted to determine whether adrenocortical activity is associated with behavior problems after controlling for significant genetic and environmental factors. Results showed that children with fragile X, especially males, had higher levels of salivary cortisol on typical days and during the evaluation. Highly significant family effects on salivary cortisol were detected, consistent with previous work documenting genetic and environmental influences on adrenocortical activity. Increased cortisol was significantly associated with behavior problems in boys and girls with fragile X but not in their unaffected siblings. These results provide evidence that the function of the hypothalamic-pituitary-adrenal axis may have an independent association with behavioral problems in children with fragile X syndrome.

The impact of panic expectancy and social demand on agoraphobic avoidance

The relationship between panic expectancy, social demand and agoraphobic avoidance was investigated in a group of 48 panic disorder subjects. Subjects were observed surreptitiously while completing a naturalistic behavioral avoidance task (BAT) involving either a high or low social challenge task. Subjects in the high social challenge task avoided more compared to subjects in the low social challenge task. Prediction of panic made before entering the situation and type of social challenge condition (high/low) were the only variables that accounted for significant amounts of unique variance in prediction of BAT score. The results confirm previous findings regarding the relationship between panic expectancy and avoidance and suggest that social interaction and scrutiny is a factor in avoidance.

Type A Behaviour And Pressor Response In Asymptomatic Middle-Aged Men

Abstract The association of pressor response with type A behaviour was investigated to identify factors underlying the inconsistent results of previous studies. Three aspects of procedure were considered comprising sample, type A measurement and type of challenge. A proper random sample of 95 men asymptomatic for ischaemic heart disease was assessed for type A behaviour using the Structured Interview, Jenkins Activity Survey, Framingham and Bortner scales. Pressor response from rest was assessed during a high social challenge task (the Structured Interview) and a low social challenge task (a difficult vigilance task). Pressor response was associated with type A behaviour only during the high social challenge task irrespective of method of type A assessment. It is concluded that the critical factor underlying inconsistent findings in this area is not lack of relationship or invalid type A measurement but the use of invalid tasks.
