[Identifying cognitive and emotional markers in relation to auditory-verbal hallucinations in pediatric population: Physalis study]

OBJECTIVES

Auditory-verbal hallucinatory experiences (AVH) represent a prevalence of 12% in the general pediatric population. They are most often considered as a transient and benign developmental phenomenon, associated with mood and anxiety disorders. The persistence of AVHs for several years and into adolescence would represent a poor prognosis of progression into a psychiatric disorder, and more particularly psychotic disorder. The alteration of social and emotional cognitive markers are described as prodromal of this unfavorable progression which should be considered within the continuum between subclinical and clinical signs of the "psychosis phenotype". The objective of this study was to assess these markers in children and adolescents with AVH and their correlation with the presence and persistence of hallucinations.

METHODS

Multicenter prospective case-control study, longitudinal over 6months. Patients were included based on the presence of HAV on clinical examination. Forty subjects aged 8 to 16years from a clinical pediatric population were included. They were divided into two groups according to the Diagnostic Interview Schedule for Children-Child version (DISC-C): a group with AVH ("AVH+"), and a group without HAV ("AVH-"). A diagnosis of schizophrenia spectrum disorder was a non-inclusion criterion according to the criteria of DSM-5 (K-SADS-PL). This group was matched to the control group without AVH (AVH-) according to sex, age (±6months) and associated psychiatric diagnoses assessed by the MINI-Kid. The marker of social cognition was assessed with the NEPSY II test. The emotional marker was assessed with the self-questionnaires: EED IV, which highlights the emotions currently being felt by the subject, and the BAVQ-R, which categorizes the child's emotions in reaction to AVH.

RESULTS

No significant link was found between the social and emotional cognition markers and the presence of AVH at T0. At 6months, 50% of subjects in the AVH+ group suffered from persistent AVH and 18% progressed to a diagnosis of schizophrenia spectrum disorder. The persistence of AVH was not significantly correlated with the marker of social cognition, but it was significantly correlated with the presence of negative emotions (sadness, fear, hostility and anger) and inversely correlated with emotions of joy.

CONCLUSION

In this study, AVH experiences in the pediatric population are not linked to markers of social cognition, but negative emotions appear as early markers of AVH persistence. CLINICALTRIALS.

COVID-19 and sleep patterns in adolescents and young adults

OBJECTIVE

In March 2020, the world experienced a global pandemic, which involved the shutdown of schools or a transposition to remote teaching in most countries. The objective of the present study was to investigate the impact of the COVID-19 pandemic related lockdown on sleep patterns and sleep quality in adolescents and young adults.

METHODS

An online survey was conducted in June 2020 with adolescents and young adults (n = 498) aged 12-25 years. Participants had to answer questions on sleep, first retrospectively, referring to the time prior to the pandemic, and then referring to the time during the pandemic.

RESULTS

A pronounced shift towards later sleep combined with an increase in sleep duration was found during the pandemic. However, these changes in sleep habits were more pronounced in adolescents than in young adults and seem to occur mostly during weekdays compared to weekends. During the pandemic, teens also reported an improvement in daytime sleepiness and subjective sleep quality, while young adults reported an increase in sleep difficulties associated with sleep onset difficulties, nocturnal and early morning awakenings, and nightmares.

CONCLUSIONS

The COVID-19 related lockdown seems to have had a beneficial effect on sleep in adolescents. In young adults, benefits are not as obvious. These results support that later school start times would be beneficial for adolescents. However, in young adults it could be important to investigate the effects of other situational or interindividual factors (stress, lifestyle habits, employment, etc.).

The SUPPORT-S Protocol Study: A Postvention Program for Professionals After Patient or User Suicide

Background

Exposure to patient or user suicide (PUS) is identified as a challenging occupational hazard for mental health and social work professionals. Professionals exposed to PUS may encounter several ranges of emotional, traumatic or professional impacts in the aftermath. A high proportion of exposed professionals reports a lack of support in the aftermath of PUS. SUPPORT is a postvention program designed to provide a comprehensive, adaptative and effective support to professionals impacted by PUS. The aims of the SUPPORT-S study are to (1) improve the design of the SUPPORT program, (2) evaluate the effectiveness of the program to buffer the emotional, traumatic and professional impacts and to improve the perceived social support for professionals exposed to PUS, and (3) provide more insights into the consequences of PUS on both professionals and organizations.

Method

The SUPPORT-S study is a mixed method collaborative and participatory action research. The simultaneous and complementary collection and analysis of qualitative and quantitative data will offer an in-depth evaluation of the implementation and the effectiveness of the program. The qualitative evaluation includes: (a) an ethnographic observation; (b) 25 semi-directed interviews with randomized participants; (c) an activity analysis with providers of the program; and (d) collaborative sharing of the results with providers and participants. The quantitative evaluation includes pre- and post-measures in participants of: (a) emotional impact (Differential Emotions Scale IV); (b) traumatic impact (Impact of Event Scale-Revised); (c) professional impact (non-validated questionnaire); and (d) perceived social support (Perceived Social Support Scale for Professionals). The action research design will rely on: (a) the cycling process of implementation/evaluation/data sharing/adjustment and (b) the participatory approach through data sharing with providers and participants. Triangulation, saturation, randomization, and participatory design will also reduce the risk of biases and will improve the generalizability of conclusions.

Expected Results

We expect the SUPPORT-S study to evaluate and improve the design of the SUPPORT program to effectively help professionals to cope with PUS.

Conclusion

The results of the study will allow us to disseminate an effective and adaptive postvention program for professionals and institutions encountering PUS.

[Blood-injection-injury phobia: Physochophysiological and therapeutical specificities]

INTRODUCTION

Seventy-five percent of patients with blood-injection-injury phobia (BII-phobia) report a history of fainting in response to phobic stimuli. This specificity may lead to medical conditions remaining undiagnosed and untreated, incurring considerable cost for the individual and society. The psychophysiology of BII-phobia remains poorly understood and the literature on effective treatments has been fairly sparse. Aims of the systematic review: to synthesize the psychophysiology of BII-phobia and to propose a systematic review of the literature on effectiveness of different treatments evaluated in this indication.

RESULTS

Firstly, the most distinct feature of the psychophysiology of BII-phobia is its culmination in a vasovagal syncope, which has been described as biphasic. The initial phase involves a sympathetic activation as is typically expected from fear responses of the fight-flight type. The second phase is characterized by a parasympathetic activation leading to fainting, which is associated with disgust. Subjects with syncope related to BII-phobia have an underlying autonomic dysregulation predisposing them to neurally mediated syncope, even in the absence of any blood or injury stimulus. Many studies report that BII-phobic individuals have a higher level of disgust sensitivity than individuals without any phobia. Secondly, behavioral psychotherapy techniques such as exposure only, applied relaxation, applied tension, and tension only, have demonstrated efficacy with no significant difference between all these techniques. The disgust induction has not improved effectiveness of exposure.

CONCLUSION

We have explained the psychophysiology of BII-phobia, the understanding of which is required to study and validate specific techniques, in order to improve the prognosis of this disorder, which is a public health issue.
