The impact of forced social comparison on adolescents' self-esteem and appearance satisfaction

The impact of forced social comparison on adolescents' self-esteem and appearance satisfaction research, conducted on a sample of 133 high school seniors, consisted of two phases. In phase one, participants were given the Rosenberg Self-Esteem Inventory, Appearance Satisfaction Scale and Appearance Relevance Scale, and in phase two, one month later, they were exposed to photographs of attractive and unattractive individuals. Two groups of boys and girls each assessed attractive or unattractive individuals of their own gender, while two control groups (of both genders) were not exposed to any photographs. Immediately after assessing the photographs, the participants were again given the Rosenberg Self-Esteem Inventory and Appearance Satisfaction Scale. We found that forced social comparison had an impact on self-esteem and a marginally significant effect on appearance satisfaction in the group of participants (of both genders) assessing the photographs of unattractive individuals, while no effects were found in the either the control group or the group assessing the photographs of attractive individuals. We also examined the impact of self-esteem, appearance satisfaction and appearance relevance as moderating variables on the effect size of social comparison and showed that higher pretest self-esteem and appearance relevance and lower appearance satisfaction predict higher posttest self-esteem scores, regardless of the participants' group membership. The group of participants exposed to photographs of unattractive people, however, showed the opposite pattern - those participants who had initially lower self-esteem have increased it more as a result of the experimental exposure

MULTIPLE FACES OF PERSONALITY DOMAINS: REVALIDATING THE PROPOSED DOMAINS

Background: Despite relatively consistent findings regarding the number of personality pathology domains, differences in domain structure remain. Recently the proposed ICD-11 domains were partially validated in a sample of patients with major depression producing five domains: Detached, Anankastic, Negative Emotional, Antisocial and Borderline. The aim of our study was to attempt to cross-validate these findings in a sample of patients primarily diagnosed with personality disorder (PD). Subjects and methods: All subjects were assessed by Structured Clinical Interview for the DSM-IV Axis II PD. Exploratory factor analysis (EFA) was applied on fifty seven DSM PD symptoms selected to represent the five proposed domains. Results: SCID II data were collected from a total of 223 subjects. The EFA extracted five factors. The first factor labeled as borderline-internalizing constituted of borderline together with avoidant and dependent items, the second, labeled as disinhibited/ borderline externalizing, incorporated narcissistic and histrionic items. The other three separate factors in our study labeled as antisocial, anankastic and detached, were less robust. Conclusions: In our study five personality pathology domains were partly replicated. The most robust findings support the existence of the two factors, borderline-internalizing and disinhibited/borderline externalizing. However, the EFA was performed on a relatively low prevalence symptoms distribution, particularly for antisocial and schizoid factors

Serbian Language version of the Modified Checklist for Autism in Toddlers, Revised, with Follow-Up: Cross-Cultural Adaptation and Assessment of Reliability

Early detection of Autism Spectrum Disorder (ASD) has proven to be of high significance, however there is a limited availability of ASD screening tools in Serbian language. In this study we aim to translate, assess reliability and, in part, test the applicability of Modified Checklist for Autism in Toddlers, Revised, with Follow-Up (M-CHAT R/F) in Serbian Healthcare environment. We screened 128 children in three primary healthcare centres and 20 children in a tertiary psychiatric center, using M-CHAT R/F translated into Serbian language, between December 2014 and October 2015. At the end of the screening process 80% of participants in the risk group screened positive for ASD, while in the control group 4 (3.1%) participants screened positive, with a mean total scores of 8.25 and 0.66 respectively. The Cronbach's a coefficient was 0.91 and Guttman's.6 was 0.93. Test-retest reliability was deemed as acceptable, and no significant correlation was found between M-CHAT-R/F scores and Epworth Sleepiness Scale for children scores. The Serbian version of the M-CHAT-R/F has shown satisfactory reliability. We can therefore assert that it is a reliable tool for identifying ASD and it can be used in clinical practice to improve early detection, assessment and treatment

Plasma Membrane Calcium ATPase-Neuroplastin Complexes Are Selectively Stabilized in GM1-Containing Lipid Rafts

The recent identification of plasma membrane (Ca2+)-ATPase (PMCA)-Neuroplastin (Np) complexes has renewed attention on cell regulation of cytosolic calcium extrusion, which is of particular relevance in neurons. Here, we tested the hypothesis that PMCA-Neuroplastin complexes exist in specific ganglioside-containing rafts, which could affect calcium homeostasis. We analyzed the abundance of all four PMCA paralogs (PMCA1-4) and Neuroplastin isoforms (Np65 and Np55) in lipid rafts and bulk membrane fractions from GM2/GD2 synthase-deficient mouse brains. In these fractions, we found altered distribution of Np65/Np55 and selected PMCA isoforms, namely PMCA1 and 2. Cell surface staining and confocal microscopy identified GM1 as the main complex ganglioside co-localizing with Neuroplastin in cultured hippocampal neurons. Furthermore, blocking GM1 with a specific antibody resulted in delayed calcium restoration of electrically evoked calcium transients in the soma of hippocampal neurons. The content and composition of all ganglioside species were unchanged in Neuroplastin-deficient mouse brains. Therefore, we conclude that altered composition or disorganization of ganglioside-containing rafts results in changed regulation of calcium signals in neurons. We propose that GM1 could be a key sphingolipid for ensuring proper location of the PMCA-Neuroplastin complexes into rafts in order to participate in the regulation of neuronal calcium homeostasis

Analysis of trauma severity and the impact of abuse and neglect on personality traits in adolescents

Introduction: Abuse and neglect might cause multiple and long-term consequences on physical and mental health, development and future life of children. The consequences that abuse and neglect cause on a child’s personality and functioning in adult life have particular importance. The aim: Determining the level of trauma, as well as differences in personality traits of adolescents who are on psychiatric treatment and has been registered in Department for the protection of children against abuse and neglect, comparing with children who are on psychiatric treatment but not abused, and control group of adolescents. Materials and methods: The study analysed three groups: abused group on psychiatric treatment, group on psychiatric treatment and not abused, and control healthy population. All subjects filled out General questionnaire with basic socio-demographical data, Childhood Trauma Questionnaire (CTQ), and Temperament and Character Adolescent Inventory (ATCI – 46). Results: There is statistically significant difference between groups in all types of abuse: physical, emotional, sexual, as well as emotional and physical neglect (p<0.001). Psychiatric group has significantly lower scores on Persistence (P) (p<0.01), while abused group has lower scores on Harm avoidance (HA) (p<0.05). Negative correlation between abuse and Self-transcendence (ST), and negative correlation between physical abuse and Self-directedness (SD) has been shown. Conclusion: Abuse and neglect in children and adolescents are a significant cause of trauma and can cause different psychopathology, as well as changes on character and temperament traits

THE ROLE OF REGIONAL CENTERS AND UNIVERSITY CHILDREN’S HOSPITAL IN DEVELOPMENT OF HOME MECHANICAL VENTILATION NETWORK

Application of home mechanical ventilators represents the future in the treatment of children with chronic respiratory insufficiency. In this way patients are treated in the home environment, they have full support from their families, they are protected against nosocomial infections and their condition is monitored by medical staff. The role of regional centers is very important in the future development of the home mechanical ventilation network. Doctors in these centers under the full support of the University Children's Hospital physicians can assist and monitor the treatment of children on the household respirators

Early screening for autistic spectrum disorders in toddlers aged 16 to 30 months

Introduction: Prevalence of autism spectrum disorders (ASD) worldwide shows a significant rise. Screening and early diagnosis are extremely important and provide a possibility for an early intervention. Objectives: This study is a part of validation process for a Serbian translation of Modified Checklist for Autism in Toddlers, Revised with Follow-up (MCHAT- R/F). Another aim was to analyse the risk factors which are associated with the development of ASD. Methods: The study included parents of toddlers aged 16 to 30 months during a well-child care visits in Dom zdravlja Savski venac and parents of toddlers sent to see a psychiatrist in Institute for mental health (IMH). Children were screened using the M-CHATR/ F. Results: The study included 65 toddlers. The ones screened in Dom zdravlja were placed in a low-risk group, and others who were referred to IMH were classified as high-risk group. Comparing these two groups no statistically significant difference was found in terms of children's age or parents' age at birth. Statistically significant difference was found in terms of gestational week at birth, and significantly higher incidence of pregnancy complications in high-risk group. Conclusion: Further investigation should completely examine the psychometric characteristics of M-CHAT, but the preliminary findings show that M-CHAT can detect many cases of ASD during a routine pediatrician examination. Some prenatal and perinatal factors such as pregnancy complications and gestational age at birth can lead to increased risk of developing ASD

Analysis of the Relationship between Higher-Order Factor Structure of Personality Disorders and the Five-Factor Model of Personality

The growing body of evidence on the dimensional classification of personality disorders (PD) has resulted in its acceptance in the ICD-11 classification, which abolished categories and retains only a general description of PD. Specifying the type of PD is optional, and the suggested domains represent maladaptive variants of the five-factor model of personality (FFM). The aim of our study was to explore the existence of a joint structure between maladaptive and normal personality traits, and to investigate how these structures are integrated. The study included 223 patients who had been diagnosed with PD and completed the Structured Clinical Interview for DSM-5 Personality Disorders and the NEO Personality Inventory-Revised (NEO-PI-R). To determine the degree of overlap between PD domains and NEO PI–R scales, a canonical analysis of covariance was conducted. Our findings showed a relationship between the internalizing PD spectrum (consisting of avoidant, dependent, and borderline traits with detached and anankastic traits) and high neuroticism, low conscientiousness, and moderately low agreeableness and extroversion, suggesting the existence of a broad personality disorder factor. However, the internalizing dimensions exhibited a more pronounced effect within this construct. Furthermore, we identified a second function that demonstrated a link between the externalizing PD spectrum (including narcissistic, histrionic, and antisocial traits) and high extraversion, high openness, and low agreeableness, suggesting the existence of an externalizing factor. Overall, our findings provide evidence for a joint structure of maladaptive and normal personality traits in a sample of personality disorders and emphasize the importance of integrating the FFM model in PD evaluation in clinical practice, suggesting that differentiating between major subgroups could assist in adjusting therapeutic approaches
