A sociocognitive approach to social problem solving in patients with traumatic brain injury: a pilot study

Theory of Mind and Suicidality: A Meta-Analysis

OBJECTIVE

Disturbances in interpersonal functioning are prevalent in individuals with suicidality. Foundational for interpersonal functioning is theory of mind (ToM), a social-cognitive ability that allows individuals to understand the thoughts and feelings of others. Recent work has begun to investigate ToM performance in individuals with suicidality, though no review has quantitatively aggregated findings from these varied studies. The current study investigated the relations between ToM and suicidality with meta-analysis.

METHOD

We identified and meta-analyzed 15 studies that presented data for 2,895 participants (617 of whom had reported at least one suicide attempt).

RESULTS

Results indicated a significant, negative relation between ToM and suicidality with a medium overall effect size (g = -.475). Moderator analyses revealed that this effect was consistent across age, sex, ToM content, and suicidal outcome.

CONCLUSION

Deficits in ToM associated with suicidality hold promise for risk-identification, treatment, and prevention work.HighlightsTheory of mind (ToM) abilities are critical for effective interpersonal functioning.Meta-analytics results indicate that ToM deficits are associated with suicidality.Identifying such suicidality-related ToM deficits may inform risk-identification, treatment, and prevention work.

Social problem solving and trait socioemotional abilities in ambulatory stroke patients

INTRODUCTION

Stroke has been associated with sociocognitive impairment, so far well documented for emotion recognition and Theory of Mind. However, more complex abilities, such as social problem solving, which directly facilitate appropriate behavior in social situations have been neglected in previous research.

METHOD

The present study aimed to address this gap by focusing on performance-based social problem solving abilities and self-reported socioemotional abilities (i.e., empathy and alexithymia) in outpatient stroke patients (n = 36) compared to a group of healthy controls (n = 36) equivalent on age, gender, and education. In further analyses, potential lateralization effects and correlations between social problem solving/socioemotional functioning and demographic and clinical data were investigated.

RESULTS

In the main analyses, patients were impaired in their ability to freely generate appropriate solutions for challenging interpersonal situations depicted in written scenarios but performed on a comparable level as healthy controls when they had to choose the optimal solution presented amidst a range of less optimal options. While showing difficulty in identifying the awkward elements in the scenarios, the patient group nevertheless rated the degree of discomfort attributed to these elements on a level comparable to the control group. On the self-report measures, stroke patients reported overall higher degrees of alexithymia (i.e., an inability to describe and identify one's own and other persons´ emotions) and more personal distress in response to other individuals´ emotional suffering as assessed by self-report.

CONCLUSIONS

The present results suggest that stroke is associated with a broad impact on socioemotional and social problem solving abilities. As difficulties in social problem solving might be associated with increased psychosocial burden they ought to be addressed in stroke rehabilitation.

Theory of mind in adults with traumatic brain injury: A meta-analysis

Studies of abnormal theory of mind (ToM) performance in adult patients with traumatic brain injury (TBI) have reported inconsistent results. Therefore, we conducted a meta-analysis to characterize ToM performance in adult patients with TBI. Random-effects models were employed to estimate the overall effect size and the differential effect sizes across different ToM aspects. Based on a sample of 28 studies (1031 patients and 865 healthy controls), the meta-analytic findings revealed that ToM was significantly impaired in adult patients with TBI compared to healthy controls (g = -1.13). Besides, patients with TBI showed significant impairments in individual ToM tasks, as well as for different stimulus modes and contents involved in these ToM tasks. A meta-regression indicated a positive association between ToM performance and Glasgow Coma Scale score. The results of the current meta-analysis suggest that the performance in ToM tasks may be a good predictor of functional outcomes in adults with TBI, which is important for the identification of targets for cognitive interventions and the development of useful training intervention programs.

The impact of cognitive-communication difficulties following traumatic brain injury on the family; a qualitative, focus group study

Primary Objective: To identify how families experience cognitive-communication difficulties following Traumatic Brain Injury (TBI). Experiences of information, training and support for managing communication changes were also explored. Research Design: Qualitative focus group methodology using thematic analysis. Method: 15 family members of individuals with cognitive-communication difficulties following severe TBI participated in the study; four parents, six spouses, three siblings and two offspring. The majority of participants were female (80%, n = 12), with a mean age of 51 (range 19-71). Four focus groups were held with family members at 0-12 months, 12-36 months and 36+ months post-injury. The data were transcribed verbatim and analyzed using NVIVO 12.Results: Cognitive-communication difficulties were found to impact upon family functioning and psychological wellbeing for several years post-injury. Changes to social cognition, insight and the "filter switch" of the person following TBI were key areas of distress. Participants highlighted the need for information about communication changes to be provided at several time points post-injury. The need for peer support from other families with experience of cognitive-communication difficulties was also identified.Conclusion: Cognitive-communication difficulties impact upon family functioning for many years following injury with families continuing to have support needs for communication well beyond the acute rehabilitation stage.

An Emotional Agent for Moral Impairment Rehabilitation in TBI Patients

The ability to identify the emotions of others is a key component of what is known as social cognition. Narratives exploit this mechanism to create an emotional bond with the characters and to maintain the engagement of the audience throughout the story. In this paper, we illustrate a case study in emotion understanding in stories that exploits a computational agent to explore emotion impairment in a group of traumatic brain injured people. The study focuses on moral emotions, aiming to investigate the differences in moral functioning that characterize traumatic brain injured patients. After comparing the understanding of the moral and emotional facets of the agent's behavior in traumatic brain injured patients and in neurologically intact controls, slight-yet meaningful-differences were observed between the two groups. We describe the test methodology and results, highlighting their implications for the design of rehabilitation applications based on virtual agents.
