Diminished social attention in pediatric brain tumor survivors: Using eye tracking technology during naturalistic social perception

[Formula: see text] Association between visual attention and parent-reported social problems in pediatric cancer survivors

Social deficits in pediatric cancer survivors have been well documented and have been linked to neurocognitive late effects, particularly attention deficits. The purpose of this study was to examine the association between components of attention, both parent-report and a performance-based measure, with parent-reported social functioning in survivors of pediatric cancer. The study included data from outpatient neuropsychological evaluations of 76 survivors of pediatric cancer. The Integrated Visual and Auditory (IVA) continuous performance test was used to evaluate the components of attention with variables corresponding to Posner's model of attention. Assessment of inattention and peer problems were derived from the Conner's Parent Rating Scale, third edition. Parent-reported attention symptoms were significantly associated with worse auditory prudence (r = -0.382, p < .001) and visual consistency (r = -0.234, p = .046) and higher parent-reported peer problems (r = 0.302, p = .008). Auditory attention domains were not significantly predictive of peer problems (p > .05). When controlling for FSIQ and type of cancer, worse visual consistency (p = .029) and visual speed (p = .036) were significantly associated with more peer problems. Parent-reported inattention was associated with only some domains of performance-based attention, highlighting the importance of using multi-modal assessments of attention. This study also revealed an important relationship between visual attention and peer problems.

Social impairment in survivors of pediatric brain tumors via reduced social attention and emotion-specific facial expression recognition

BACKGROUND/OBJECTIVES

Survivors of pediatric brain tumors (SPBT) experience significant social challenges, including fewer friends and greater isolation than peers. Difficulties in face processing and visual social attention have been implicated in these outcomes. This study evaluated facial expression recognition (FER), social attention, and their associations with social impairments in SPBT.

METHODS

SPBT (N = 54; ages 7-16) at least 2 years post treatment completed a measure of FER, while parents completed measures of social impairment. A subset (N = 30) completed a social attention assessment that recorded eye gaze patterns while watching videos depicting pairs of children engaged in joint play. Social Prioritization scores were calculated, with higher scores indicating more face looking. Correlations and regression analyses evaluated associations between variables, while a path analysis modeling tool (PROCESS) evaluated the indirect effects of Social Prioritization on social impairments through emotion-specific FER.

RESULTS

Poorer recognition of angry and sad facial expressions was significantly correlated with greater social impairment. Social Prioritization was positively correlated with angry FER but no other emotions. Social Prioritization had significant indirect effects on social impairments through angry FER.

CONCLUSION

Findings suggest interventions aimed at improving recognition of specific emotions may mitigate social impairments in SPBT. Further, reduced social attention (i.e., diminished face looking) could be a factor in reduced face processing ability, which may result in social impairments. Longitudinal research is needed to elucidate temporal associations between social attention, face processing, and social impairments.

Social participation of school-aged survivors of pediatric brain tumors: A daily diary report

BACKGROUND

Difficulties with social functioning are common among survivors of pediatric brain tumors. Social participation is an understudied measure of social functioning that is associated with emotional health across the lifespan. This paper uses a diary method to assess the social participation of survivors of pediatric brain tumors in middle childhood.

PROCEDURE

Survivors of pediatric brain tumors (N = 47; age 10.6 ± 1.4 years; 51.1% male, 89.4% White) who were 5.3 (SD = 2.4, range: 2-9.9) years post therapy completed a daily diary assessment of social interaction (5-7 days) and an objective measure of facial affect recognition. The participant's caregiver completed the NIH Toolbox Emotion Measures and a background information questionnaire.

RESULTS

Overall, frequency and quality of reported social interactions were low for survivors, with a large subset of survivors (n = 16, 34%) endorsing fewer than 10 social interactions over the course of a typical school week, and almost half of parents (48.9%) reporting that their child participates in zero social activities outside of school during a typical week. Participants engaged in more positive social participation exhibited stronger social skills (facial affect recognition (F(2,44)  = 4.85, p < .05).

CONCLUSIONS

School-aged survivors of pediatric brain tumors seemed to be infrequently engaged in social participation and quality interaction with peers. More specifically, the interactions most commonly reported on the diary assessment are not indicative of friendship development and maintenance. Survivors of pediatric brain tumors would likely benefit from interventions designed to increase quality time spent with peers.

The psychological impact of adult-onset craniopharyngioma: A qualitative study of the experience of patients and clinicians

PURPOSE

Individuals who experience social and emotional difficulties struggle to maintain successful social relationships and incur an increased risk of developing mood disorders. These, in turn, have a significant impact on psychological and physical wellbeing. A small number of medical studies suggest that patients with adult-onset craniopharyngioma (AoC) report poorer quality of life, however, no in-depth psychological research has been carried out. The present study aimed to capture a rich understanding of whether patients with AoC experience a psychological impact from their diagnosis and whether psychological factors may contribute to a poorer quality of life.

METHOD

Both patients with AoC and clinicians with experience of working with patients with AoC were invited to take part in a semi-structured interview. Participants were recruited from three geographically disperse National Health Service (NHS) units across the United Kingdom (UK). Eight patients and 10 clinicians took part in the study. Interviews were recorded and transcribed verbatim and analysed using inductive thematic analysis.

RESULTS

Two key themes, with multiple subthemes, were identified: 1) Patients experience psychological impacts of AoC; and 2) Patients also experience common physical symptoms.

CONCLUSIONS

Patients and clinicians recognised significant psychological impact as a result of AoC, and these impacts contributed to overall poorer quality of life. Crucially, both parties also felt that further research into psychological impact of AoC was both interesting and useful.

Executive and social functioning in pediatric posterior fossa tumor survivors and healthy controls

Background

Executive and social functioning difficulty is well established in pediatric brain tumor survivors. Few studies have compared posterior fossa (PF) tumor survivors in comparison to their peers. The relationship between attention, processing speed, working memory, fatigue, and executive and social functioning was investigated to better understand the factors that impact executive and social functioning in PF tumor populations.

Methods

Sixteen medulloblastomas, 9 low-grade astrocytomas (LGAs), and 17 healthy controls recruited from 4 sites completed measures of working memory and processing speed, and self-reported fatigue. One parent completed questionnaires on executive and social functioning.

Results

There were no significant differences among all 3 groups on parent-reported executive and social functioning; of note, parents of LGA survivors expressed greater concerns regarding behavioral and cognitive regulation than did parents of medulloblastoma survivors and healthy controls. Parent-reported attention was related to parent-reported emotion, behavior, and cognitive regulation. Worse self-reported fatigue was associated with greater emotional dysregulation for the 2 PF tumor groups.

Conclusions

Parents of PF tumor survivors described their children as performing similarly to their peers in most facets of executive and social functioning. While LGA survivors are traditionally thought to have more favorable outcomes, our finding of parent-reported executive functioning concerns to be worse for this group highlights the importance of long-term follow-up for all PF tumor survivors. Additionally, significant effects of attention on aspects of executive functioning in PF tumor survivors may inform current clinical practice and the future development of more effective interventions.

Reduced Fusiform Gyrus Activation During Face Processing in Pediatric Brain Tumor Survivors

OBJECTIVE

The neural mechanisms contributing to the social problems of pediatric brain tumor survivors (PBTS) are unknown. Face processing is important to social communication, social behavior, and peer acceptance. Research with other populations with social difficulties, namely autism spectrum disorder, suggests atypical brain activation in areas important for face processing. This case-controlled functional magnetic resonance imaging (fMRI) study compared brain activation during face processing in PBTS and typically developing (TD) youth.

METHODS

Participants included 36 age-, gender-, and IQ-matched youth (N = 18 per group). PBTS were at least 5 years from diagnosis and 2 years from the completion of tumor therapy. fMRI data were acquired during a face identity task and a control condition. Groups were compared on activation magnitude within the fusiform gyrus for the faces condition compared to the control condition. Correlational analyses evaluated associations between neuroimaging metrics and indices of social behavior for PBTS participants.

RESULTS

Both groups demonstrated face-specific activation within the social brain for the faces condition compared to the control condition. PBTS showed significantly decreased activation for faces in the medial portions of the fusiform gyrus bilaterally compared to TD youth, ps ≤ .004. Higher peak activity in the left fusiform gyrus was associated with better socialization (r = .53, p < .05).

CONCLUSIONS

This study offers initial evidence of atypical activation in a key face processing area in PBTS. Such atypical activation may underlie some of the social difficulties of PBTS. Social cognitive neuroscience methodologies may elucidate the neurobiological bases for PBTS social behavior.

Cognitive predictors of social adjustment in pediatric brain tumor survivors treated with photon versus proton radiation therapy

BACKGROUND

Pediatric brain tumor survivors are at risk for poor social outcomes. It remains unknown whether cognitive sparing with proton radiotherapy (PRT) supports better social outcomes relative to photon radiotherapy (XRT). We hypothesized that survivors treated with PRT would outperform those treated with XRT on measures of cognitive and social outcomes. Further, we hypothesized that cognitive performance would predict survivor social outcomes.

PROCEDURE

Survivors who underwent PRT (n = 38) or XRT (n = 20) participated in a neurocognitive evaluation >1 year post radiotherapy. Group differences in cognitive and social functioning were assessed using analysis of covariance (ANCOVA). Regression analyses examined predictors of peer relations and social skills.

RESULTS

Age at evaluation, radiation dose, tumor diameter, and sex did not differ between groups (all p > .05). XRT participants were younger at diagnosis (XRT M = 5.0 years, PRT M = 7.6 years) and further out from radiotherapy (XRT M = 8.7 years, PRT M = 4.6 years). The XRT group performed worse than the PRT group on measures of processing speed (p = .01) and verbal memory (p < .01); however, social outcomes did not differ by radiation type. The proportion of survivors with impairment in peer relations and social skills exceeded expectation; χ² (1) = 38.67, p < .001; χ² (1) = 5.63, p < .05. Household poverty predicted peer relation difficulties (t = 2.18, p < .05), and verbal memory approached significance (t = -1.99, p = .05). Tumor diameter predicted social skills (t = -2.07, p < .05).

CONCLUSIONS

Regardless of radiation modality, survivors are at risk for social challenges. Deficits in verbal memory may place survivors at particular risk. Results support monitoring of cognitive and social functioning throughout survivorship, as well as consideration of sociodemographic risk factors.

Social Problem Solving in Survivors of Pediatric Brain Tumor

OBJECTIVES

Psychosocial late effects among survivors of pediatric brain tumors are common. For school-aged survivors, social skills deficits and isolation present a particular challenge. Social problem-solving is a social skill that is an important determinant of social outcomes and may yield a potential target for intervention.

METHODS

School-aged youth (N = 65) 8-12 years of age (10.59 ± 1.36 years; 55.4% female, 86.2% white) who were 5.23 (SD = 2.44, range 2-10.9) years post-treatment for a brain tumor completed the Attributions and Coping Questionnaire, a measure of social problem-solving that uses vignettes to assess attribution of intent, subsequent emotional response, and imagined behavioral response to an interpersonal problem. Youth also completed self-reports of social functioning (PROMIS Peer Relationships, Self-Perception Profile). A caregiver completed additional measures of child social functioning (NIH Toolbox-Emotion Measures).

RESULTS

Survivors attributed unpleasant situations to accidental causes (neutral attribution) and responded in ways that prioritized the friendship (appeasement) or relied on adult intervention. Self-reported social functioning was higher among those who were less likely to avoid challenging social problem-solving situations.

CONCLUSIONS

Findings identified characteristic social problem-solving approaches among survivors, including a tendency to attribute ambiguous situations to accidental causes and to request adult assistance and/or maintain social relationships. This may indicate a possible avenue for intervention, with a focus on increasing survivors' understanding of the causes of potentially negative peer interactions and reducing their reliance on adults.

Face Processing and Social Functioning in Pediatric Brain Tumor Survivors

OBJECTIVE

Pediatric brain tumor survivors (PBTS) experience deficits in social functioning. Facial expression and identity recognition are key components of social information processing and are widely studied as an index of social difficulties in youth with autism spectrum disorder (ASD) and other neurodevelopmental conditions. This study evaluated facial expression and identity recognition among PBTS, youth with ASD, and typically developing (TD) youth, and the associations between these face processing skills and social impairments.

METHODS

PBTS (N = 54; ages 7-16) who completed treatment at least 2 years prior were matched with TD (N = 43) youth and youth with ASD (N = 55) based on sex and IQ. Parents completed a measure of social impairments and youth completed a measure of facial expression and identity recognition.

RESULTS

Groups significantly differed on social impairments (p < .001), with youth with ASD scoring highest followed by PBTS and lastly TD youth. Youth with ASD performed significantly worse on the two measures of facial processing, while TD youth and PBTS were not statistically different. The association of facial expression recognition and social impairments was moderated by group, such that PBTS with higher levels of social impairment performed worse on the expression task compared to TD and ASD groups (p < .01, η2 = 0.07).

CONCLUSIONS

Variability in face processing may be uniquely important to the social challenges of PBTS compared to other neurodevelopmental populations. Future directions include prospectively examining associations between facial expression recognition and social difficulties in PBTS and face processing training as an intervention for PBTS.

Social–Emotional Functioning in Preschool-Aged Children With Cancer: Comparisons Between Children With Brain and Non-CNS Solid Tumors

Objectives 

The preschool years (ages 4–6) are essential for the development of social–emotional skills, such as problem solving, emotion regulation, and conflict resolution. For children with cancer treated during this period, especially those with brain tumors, there are questions regarding the consequences of missed normative social experiences. The objective of this pilot study was to explore the social–emotional functioning of young children with brain tumors, as compared to those with non-CNS solid tumors, who have recently completed treatment.

Methods 

Children with brain (n = 23) or solid tumors (n = 20) 4–6 years of age (5.42 ± 0.73 years; 60.5% male, 65.1% white) who were 8.21 (SD = 2.42) months post-treatment completed objective measures (Challenging Situations Task, NEPSY-II) of social functioning while a caregiver completed questionnaires (e.g., BASC-3, NIH Toolbox Emotion Measures).

Results 

A large portion of the sample (brain tumor: 65.2%, solid tumor: 44.4%) fell in the clinical range on parent-report measures of peer interaction. There were no statistically significant differences between patient groups across measures, but effect sizes suggest youth with brain tumors potentially experienced more difficulties on some indices. All children were more likely to choose prosocial responses when presented with a challenging social situation where they were physically provoked (e.g., hit) versus socially provoked (e.g., left out).

Conclusions 

Preschool-aged children with cancer may experience weaknesses in social functioning shortly after treatment, with youth with brain tumors potentially demonstrating greater concerns. Emphasizing social interaction is critical to ensure young children have the opportunity to develop critical social–emotional skills.

A Novel Approach to Understanding Social Behaviors in Pediatric Brain Tumor Survivors: A Pilot Study

BACKGROUND/OBJECTIVES

Pediatric brain tumor survivors (PBTS) are at risk of experiencing challenges in social adjustment. However, the specific social behaviors of PBTS have rarely been directly assessed. This pilot study explores the first novel use of the Autism Diagnostic Observation Schedule, second edition (ADOS-2), to evaluate the social behaviors of PBTS.

METHODS

Twenty-six PBTS (ages 9-17 years; M = 7.8 years from diagnosis; 52% male; 41% received radiation treatment) completed the ADOS-2. The proportion of the sample experiencing impairment was examined descriptively across all items of the ADOS-2, as well as by a summary "overall score" created for this study, and using the ADOS-2 "diagnostic algorithm" scores for autism. Social adjustment, cognitive, medical, and demographic variables were explored as correlates of the ADOS-2 "overall score".

RESULTS

Study recruitment was 34%, impeded by distance from the tertiary-care center. The percentage of PBTS experiencing detectable impairments ranged from 0% to 50% across ADOS-2 items. Cranial radiation treatment, lower IQ, and slower cognitive processing were associated with higher impairment on the ADOS-2 "overall score".

CONCLUSION

The ADOS-2 can be used to assess the discrete social behaviors of PBTS. This study provides a foundation for future investigations using the ADOS-2 to assess social behaviors in this population. Identifying specific social behavior difficulties in PBTS is key to refining much needed targeted social skills interventions for this population.
