Impulsivity in adolescent girls diagnosed with trichotillomania: an evaluation of clinical and neuropsychological characteristics.

The aim of this study is to compare the clinical and neuropsychological features of impulsivity in adolescent girls with trichotillomania (TTM) and healthy controls, and to assess the relationships between the severity of TTM and the impulsivity/concomitant symptoms of anxiety and depression. The study sample consisted of 43 adolescent girls who were 12 to 18 years old. The Kiddie-Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version DSM-5 (K-SADS-PL) was administered to the adolescents and their parents. All of the participants completed a sociodemographic data form, the Revised Children's Anxiety and Depression Scale-Child Version (RCADS-CV), the Barratt Impulsiveness Scale-Brief (BIS-Brief), and the Massachusetts General Hospital Hairpulling Scale (MGH-HPS). The Eriksen Flanker task, the Stop Signal Reaction Time (SSRT) task, the Go/No-Go task, and the Balloon Analog Risk Task (BART) were used to assess behavioral impulsivity. The adolescents with TTM reported higher levels of impulsivity and anxiety/depression symptoms than the healthy controls, and they also performed worse on the behavioral tasks. While there were no relationships between clinical and behavioral impulsivity and TTM severity, social anxiety symptoms were the most important predictor of the severity of TTM. It seems important to better understand the role of impulsivity in the onset and persistence of TTM symptoms in adolescents.

Parenting styles, perceived social support and emotion regulation in adolescents with internet addiction.

AIM: The aim of this study is to investigate parental attitudes, perceived social support, emotion regulation and the accompanying psychiatric disorders seen in adolescents who, having been diagnosed with Internet Addiction (IA), were referred to an outpatient child and adolescent psychiatric clinic. METHODS: Of 176 adolescents aged 12-17, 40 were included in the study group. These scored 80 or higher on Young's Internet Addiction Test (IAT) and met Young's diagnostic criteria for IA based on psychiatric interviews. Forty adolescents who matched them in terms of age, gender and socio-economic level were included in the control group. The Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS-PL), the Parenting Style Scale (PSS), the Lum Emotional Availabilty of Parents (LEAP), the Social Support Appraisals Scale for Children (SSAS-C), the Difficulties in Emotion Regulation Scale (DERS) and the Toronto Alexithymia Scale-20 (TAS-20) were applied. RESULTS: The results showed that the parents of adolescents with IA were more frequently inadequate in acceptance/involvement, supervision/monitoring and they had less emotional availability. The adolescents with IA had less perceived social support, greater difficulty in the identification and verbal expression of their feelings and emotion regulation. Lower parental strictness/supervision, higher alexithymia and the existence of an anxiety disorder were found to be significant predictors of IA. Internet addicted adolescents with comorbid major depressive disorder had higher levels of alexithymia and lower levels of emotional availability in their parents. CONCLUSION: It can be concluded that strategies for the prevention and treatment of IA in adolescents should focus on improving the quality of parenting parent-adolescent relationships, enhancing perceived social support and emotion regulation while reducing the associated psychiatric symptoms in adolescents.

The prevalence of childhood psychopathology in Turkey: a cross-sectional multicenter nationwide study (EPICPAT-T).

AIM: The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey. METHOD: A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently. RESULTS: Overall prevalence of any psychopathology was 37.6% without impairment criterion, and 17.1% with impairment criterion. Attention-deficit hyperactivity disorder was the most frequent diagnosis, followed by anxiety (19.5% and 16.7% without impairment, 12.4% and 5.3% with impairment, respectively). Lower education level and presence of a physical or psychiatric problem of the parents were independent predictors of any psychopathology of the offspring. CONCLUSION: This is the largest and most comprehensive epidemiological study to determine the prevalence of psychopathologies in children and adolescents in Turkey. Our results partly higher than, and partly comparable to previous national and international studies. It also contributes to the literature by determining the independent predictors of psychopathologies in this age group.

Emotion regulation, emotion recognition, and empathy in adolescents with anorexia nervosa.

PURPOSE: Emotional functions may play an important role in anorexia nervosa (AN). The onset of the disorder generally occurs during adolescence, which is a critical period of emotional development. However, most studies that evaluated emotional functions in AN were conducted in adult patients. The aim of this study was to evaluate emotion regulation, emotion recognition, and empathy skills in adolescent girls with AN by controlling for the effects of depression and anxiety symptoms, childhood traumatic experiences, and attachment security on emotional functions. METHODS: Thirty-two adolescent girls with AN and 32 healthy counterparts completed the Difficulties in Emotion Regulation Scale, the Reading the Mind in the Eyes Test, Toronto Alexithymia Scale-20, and the Child and Adolescent KA-SI Empathic Tendency Scale-Adolescent Form. RESULTS: The results revealed that adolescents with AN were found to have more difficulties in emotion regulation, higher alexithymic tendencies, and lower empathy skills compared with the control group. However, emotion recognition was not found to be significantly different between the two groups. These results were the same when controlling for the effects of depression and anxiety symptoms, childhood traumatic experiences, and attachment security except for empathy skills. Alexithymia and depressive symptoms were significantly related to emotion regulation difficulties in adolescents with AN. CONCLUSIONS: Considering the results, it seems that emotion regulation and alexithymia may play a crucial role in the development and maintenance of AN. Accordingly, it is necessary to focus on the improvement of these skills during the treatment of AN. Furthermore, interventions promoting these skills during adolescence may be preventive. LEVEL OF EVIDENCE: Level III, case-control study.

Familial psychological factors are associated with encopresis.

BACKGROUND: The aim of this study was to assess maternal psychiatric symptoms, family functioning and parenting styles in children with encopresis. METHODS: Forty-one children with encopresis were compared to 29 children without any psychiatric disorder. RESULTS: Higher maternal psychiatric symptoms were found in children with encopresis. The general family functioning and strictness/supervision in parenting were significant predictors of encopresis. CONCLUSIONS: Family functioning may be screened in children with encopresis, especially when standard interventions have had limited success. Identification and treatment of familial factors may enhance the treatment efficacy in encopresis.

Neural correlates of distorted body images in adolescent girls with anorexia nervosa: How is it different from major depressive disorder?

Body image disturbance is closely linked to eating disorders including anorexia nervosa (AN). Distorted body image perception, dissatisfaction and preoccupation with weight and shape are often key factors in the development and maintenance of these disorders. Although the pathophysiological mechanism of body image disorder is not yet fully understood, aberrant biological processes may interfere with perceptive, cognitive and emotional aspects of body image. This study focuses on the neurobiological aspects of body image disturbance. The sample consisted of 12 adolescent girls diagnosed with AN, nine girls with major depressive disorder (MDD) and 10 without psychiatric diagnoses (HC, the healthy control group). We applied a block-design task in functional magnetic resonance imaging using participants' original and distorted overweight and underweight images. After imaging, the participants scored the images for resemblance, satisfaction and anxiety levels. The findings of this study demonstrate that overweight images elicited dissatisfaction and increased occipitotemporal activations across all participants. However, no difference was found between the groups. Furthermore, the MDD and HC groups showed increased activations in the prefrontal cortex and insula in response to underweight images compared to their original counterparts, whereas the AN group exhibited increased activations in the parietal cortex, cingulate gyrus and parahippocampal cortex in response to the same stimuli.

The impact of the prolonged COVID-19 pandemic on adolescents with eating disorders: a follow-up study from Türkiye.

BACKGROUND: At the onset of the pandemic, we conducted a study on adolescents with eating disorders (EDs) and found no deterioration in ED symptoms. The objective of this subsequent study was to conduct a follow-up evaluation of the same cohort and investigate the consequences of the prolonged pandemic. METHODS: This longitudinal study was conducted one year after the first study between May 2021 and June 2021 with 37 adolescents aged 12-18 years (pre-existing EDs). The reassessment included an evaluation of sociodemographic and clinical characteristics, the impact of pandemic-related restrictions on ED behaviors, well-being, and quality of life. All the participants underwent a re-administration of the ED examination questionnaire (EDE-Q), Beck Depression Inventory, the State Anxiety Inventory for Children, and the Maudsley Obsessive Compulsive Inventory. RESULTS: No significant difference was observed in the EDE-Q scores or the ED examination questionnaire scores between the initial (T1) and subsequent (T2) study. The ED-related quality of life was seen to have slightly improved in the later stage. While depression (T1: 18, T2: 15, p=0.883) and obsession scores (T1: 11, T2: 14, p: 0.536) showed no disparity between the studies, anxiety scores (T1: 38, T2: 43, p:0.011) exhibited a significant increase. CONCLUSIONS: Consistent with the early phase, no exacerbation of ED symptoms in adolescents was observed during the later stages of the pandemic. Close clinical monitoring during the pandemic might have been protective against the deteriorating effects of the pandemic. During social isolation, it is important to monitor adolescents with EDs continously for depression and anxiety.

Health-related quality of life in adolescents with psychogenic nonepileptic seizures.

The aim of this study was to evaluate the health-related quality of life (HRQoL) in adolescents with psychogenic nonepileptic seizures (PNESs) and to identify factors affecting the quality of life in these patients. Thirty-four adolescents with PNESs were compared to 30 adolescents without any psychiatric disorder. The Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime Version (K-SADS-PL) was applied to determine comorbid psychiatric disorders in the study group and to rule out any psychiatric disorder in the control group. The Pediatric Quality-of-Life Inventory (PedsQL) was used to assess the HRQoL. Physical HRQoL and psychosocial HRQoL, including emotional and school functioning, were found to be significantly lower in adolescents with PNESs. In the group with PNESs, the physical HRQoL and total HRQoL of adolescents with somatoform disorders other than PNESs and the emotional functioning of adolescents with major depressive disorder were worse than those of the adolescents without these comorbid psychiatric disorders. Seizure frequency and the duration of symptoms were not correlated with HRQoL scores. Treatment strategies in adolescents with PNESs should regard comorbid unexplained somatic symptoms and psychiatric disorders in addition to the reduction or cessation of seizures.

Identity status and attachment in adolescents with attention deficit hyperactivity disorder.

Identity and attachment are two concepts of different theories that might be related and that are developmentally very important in adolescence. The aim of this study was to explore the sense of identity, attachment styles and their relation in a group of adolescents with attention deficit hyperactivity disorder (ADHD). Thirty-four adolescents who were diagnosed with ADHD in childhood were reevaluated at the age of 13-16 years. The comparison group consisted of age- and gender-matched adolescents without a psychiatric disorder. The Sense of Identity Assessment Form (SIAF) and the Relationship Scales Questionnaire (RSQ) were used to examine the sense of identity and attachment styles of adolescents, respectively. Compared to adolescents without a psychiatric disorder, adolescents with ADHD, independent of the presence of a comorbid psychiatric disorder, had a similar identity formation process; however, adolescents with ADHD and a comorbid psychiatric disorder experienced more preoccupied attachment styles. Comorbid psychiatric disorders seem to be related to the insecure attachment patterns in adolescents with ADHD.

Body Focused Repetitive Behavior Disorders: Behavioral Models and Neurobiological Mechanisms. / Beden Odakli Tekrarlayici Davranis Bozukluklari: Davranis Modelleri ve Nörobiyolojik Mekanizmalar.

OBJECTIVE: Body Focused Repetitive Behaviors (BFRB) is an umbrella term for undesirable, repetitive motor activities such as Trichotillomania (TTM), Skin Picking Disorder (SPD), nail biting, cheek chewing, lip biting, finger sucking, finger cracking and teeth grinding. Such behaviors are engaged in to eliminate a part of the body and may result in impaired functionality. The frequency of presentation to clinicians is low since BFRB are defined as harmless, although the number of studies on this condition has increased rapidly recently, including those making a clear determination of epidemiological data, those investigating the etiopathogenesis and those providing treatment guidelines, although they remain inadequate. The present study provides a review of studies investigating the etiology of BFRB to date. METHOD: Articles published between 1992 and 2021 stored in the Pubmed, Medline, Scopus and Web of Science databases were reviewed, and the prominent research studies of the condition identified were included in the evaluation. RESULTS: Studies investigating the etiopathogenesis of BFRB were found in most cases to investigate adult populations, and were hampered by such confounding factors as clinical heterogeneity, high rates of comorbid psychiatric diseases and small sample sizes. The identified studies reveal that attempts have been made to explain BFRB based on behavioral models, and that the condition is inherited at a high rate. Treatment planning is mostly associated with monoamine systems (especially glutamate and dopamine) and interventions were directed to addiction elements. Furthermore, cognitive flexibility and motor inhibition defects in neurocognitive area and cortico-striato-thalamocortical cycle abnormalities in neuroimaging studies have been reported. CONCLUSION: Studies investigating the clinical features, incidence, etiopathogenesis and treatment of BFRB, which holds a controversial place in psychiatric classification systems, would contribute to a better understanding of the disease and a more appropriate definition of the condition.

Mindful Eating, Body Weight, and Psychological Well-Being in Adolescence.

Background: This study investigated the relationships among psychological well-being, mindful eating, and weight in adolescents. Methods: Data of this cross-sectional study were collected from students of three high schools. Various questionnaires regarding mindful eating, eating behavior, emotion regulation, self-esteem, coping, body attitude, depression, and anxiety were given. BMI percentile was calculated and four groups were detemined. Hacettepe University Non-Inventional Clinical Researches Review Board approved the study (GO 18/1116). Results: Among 401 participants (59.1% girls), 16 adolescents (4.0%) were underweight, 295 (73.6%) were normal, 62 (15.5%) were overweight, and 28 (7.0%) were obese. Emotional and external eating were more common in girls. Restrictive eating was distinguishing between all adolescents, except ones with obesity and overweight. Adolescents with obesity perceived themselves as the least self-confident, attractive, and healthy, while the opposites were true for adolescents with normal weight. The groups that differed mostly from each other were normal weight and overweight. Conclusions: The psychological well-being of being overweight should not be underestimated. Emotional and external eating were correlated with low mindful eating, and gender differences were found in different aspects of mindful eating types. Calorie information and healthy eating interventions may be beneficial in boys, while interventions targeting to understand physical and emotional states may be beneficial in girls during the treatment of disordered eating behaviors.

The effects of the COVID-19 lockdown on adolescents with an eating disorder and identifying factors predicting disordered eating behaviour.

AIM: To evaluate the impact of the COVID-19 lockdown on adolescents with eating disorders (ED) and identify factors predicting ED behaviour. METHOD: This study took place during an age-stratified lockdown for those under 20 years in Turkey. Participants completed a survey developed to evaluate the effects of the lockdown on ED behaviour, well-being and quality of life (QoL) and additionally the eating disorder examination questionnaire (EDE-Q), and scales for depression, anxiety and obsessive-compulsive behaviour. The relationship between the EDE-Q-global score and other variables related to ED was examined. Linear regression analysis was performed to examine the predictive power of these variables on ED behaviour. RESULTS: Thirty-eight ED patients with a mean age of 15.12 ± 1.56 years were included in the study. Of participants, 42.1% reported feeling an improvement in ED symptomatology, 71.0% reported none or rare conflict with parents due to eating, 39.5% reported often or always complying with their meal plan. Of participants, 92.0% agreed to 'understanding the value of being healthy' and stated realizing that 'they were in control' due to the pandemic. Of participants 36.9% scored 'bad' for both overall and ED related QoL. In the stepwise regression analysis depression score had the highest predictive value for ED behaviour. CONCLUSION: Almost half of the participants felt an improvement in their ED and a majority reported rare parental conflict. However, less than half reported meal plan compliance. As depression had the highest positive predictive value for ED behaviour additional screening for depression during the pandemic maybe warranted in ED patients.

Effect of Impairment on the Prevalence and Comorbidities of Attention Deficit Hyperactivity Disorder in a National Survey: Nation-Wide Prevalence and Comorbidities of ADHD.

OBJECTIVE: This study aimed to determine the prevalence and comorbidities of attention-deficit hyperactivity disorder (ADHD) by evaluating a large-scale nation-wide sample of children. METHOD: The inclusion criterion was being enrolled as a 2nd, 3rd, or 4th-grade student. A semi-structured diagnostic interview (K-SADS-PL), DSM-IV-Based Screening Scale for Disruptive Behavior Disorders, and assessment of impairment (by both parents and teachers) were applied to 5,842 participants. RESULTS: The prevalence of ADHD was 19.5% without impairment and 12.4% with impairment. Both ADHD with and without impairment groups had similar psychiatric comorbidity rates except for oppositional defiant disorder (ODD) and conduct disorder (CD) diagnoses. Impairment in the ADHD group resulted in significantly higher ODD and CD diagnoses. CONCLUSION: Even when impairment is not described, other psychiatric disorders accompany the diagnosis of ADHD and may cause impairment in the future. Impairment in the diagnosis of ADHD significantly increases the likelihood of ODD and CD.

Environmental risk factors in pediatric psoriasis: a multicenter case-control study.

To analyze the effect of possible risk factors, including breastfeeding, on the development of childhood-onset psoriasis, a multicenter case-control study with prospective collection of data was performed. Using a standard questionnaire, personal and specific variables including family history of psoriasis, maternal and environmental tobacco smoke exposure, body mass index (BMI), exclusive and partial breastfeeding for at least 3 and 12 months, cow's milk intake before 1 year, birth delivery method, and stressful life events were collected during 2009 from 537 patients with psoriasis and 511 controls younger than 18. Overall, patients more frequently reported exposure to environmental tobacco smoke at home and stressful life events in the year preceding the diagnosis than controls. The odds ratios (OR) for smoking and stressful life events were 2.90 (95% confidence interval [CI]=2.27-3.78) and 2.94 (95% CI=2.28-3.79), respectively. In addition, children with psoriasis were more likely to have a higher BMI (>26) than controls (OR=2.52; 95% CI=1.42-4.49). High BMI, environmental tobacco smoke exposure at home, and stressful life events may influence the development of pediatric psoriasis.

Autistic Traits and Social Responsiveness: The Relationship Between Autistic Traits and Comorbid Psychiatric Symptoms in Adolescents with Anorexia Nervosa.

INTRODUCTION: It is known that patients with anorexia nervosa (AN) display social difficulties like social responsiveness and high levels of autistic behaviors such as rigidity, narrow interests of food and weight; however it is not clear whether they have comorbid Autism Spectrum Disorders (ASD) or it is about acute phase of illness. In this study it is aimed to investigate autistic traits and social responsiveness in adolescents with AN. METHODS: Study group was consisted of 39 female AN patients aged between 12-18 years. Control group was consisted of 34 female adolescents who did not have any psychiatric disorder. K-SADS-PL was applied to all participants in order to detect the psychiatric disorders. Autism traits and social responsiveness were evaluated using Social Responsiveness Scale. All adolescents of the study were administered The Eating Attitude Test, Beck Depression Inventory, Screen for Child Anxiety and Related Disorders, Maudsley Obsesive Compulsive Inventory. RESULTS: Results of the study indicated that adolescents with AN had higher symptoms of depression, anxiety and autism-like symptom clusters; and lower social responsiveness. Psychiatric comorbidities were not associated with these difficulties. CONCLUSION: The results show that AN patients have an impairment of social responsiveness, the impairment seems to be associated with AN regardless of psychiatric comorbidities. Despite these two disorders are considered unrelated, they have several traits in common. These results suggest that there may be a common pathogenesis between ASD and AN.

Relationship disorders and cognitive functioning in young children.

The aim of this study was to investigate the cognitive functioning of young children with or without relationship disorders with their mother. Mother-infant dyads were recruited during the first three postpartum days. Parent Infant Relationship Global Assessment Scale (PIRGAS) scores and mother-child relationship disorders were decided when children were 41-49 months of age by integrating the data obtained from psychiatric interview with mothers, Clinical Problem Solving Procedure (CPSP) and home observation. Cognitive functioning of young children was evaluated with Stanford-Binet Intelligence Scale. The young children without relationship problems/disorders had higher intelligence quotient (IQ) scores even after controlling for the effect of independent variables on cognitive functioning. These findings suggest that there is a link between the quality of the mother-child relationship and cognitive functioning in young children. Therefore, physicians should assess the interactions of children with their mothers even if they are brought for reasons other than relationship problems.

Attachment Security and Perceived Expressed Emotion in Adolescents with Anorexia Nervosa. / Anoreksiya Nervoza Tanisi Alan Ergenlerde Algilanan Duygu Disavurumu ve Baglanma Güvenligi.

OBJECTIVE: The aim of this study was to compare the attachment security and perceived expressed emotion of female adolescents diagnosed with anorexia nervosa and those without any psychiatric disorder and to compare the expressed emotion of their parents. We also aimed to investigate the relationships between these variables and the effects of depression and anxiety symptoms of the adolescents on attachment security, perceived expressed emotion and expressed emotion of the parents. METHOD: The study enrolled 43 female adolescents aged 12-18 years diagnosed with anorexia nervosa and an age and economic statusmatched control group of 37 healthy female adolescents. Both groups completed the Eating Attitudes Test-40 (EAT-40), the Perceived Expressed Emotion Scale (PEES), the Short Form of Inventory of Parentand Peer Attachment (IPPA), the Beck Depression Inventory (BDI) and the Screenfor Child Anxietyand Related Disorders (SCARED). Parents were assessed with the Expressed Emotion Scale (EES). RESULTS: As compared to the control group, the female adolescents with anorexia nervosa had lower attachment security and higher perception of parental expression of criticism and hostility. Presence of depression and anxiety symptoms did not affect these results. The security of maternal attachment in the adolescents with anorexia nervosa predicted their perception of criticism and hostility in their mothers. CONCLUSION: The results of this study indicate the importance of assessing attachment security and perceived expressed emotion in adolescents with anorexia nervosa and the requirement of parental inclusion in the therapeutic process during follow up for implementation of appropriate interventions.

[Comparison of attachment-related social behaviors in autistic disorder and developmental disability]. / Otistik Bozukluk ve Gelisim Geriliginde Baglanmaya Yönelik Sosyal Davranislarin Karsilastirilmasi.

OBJECTIVE: This study examined social behaviors related to attachment in children with autistic disorder and the differences in these behaviors from those observed in developmentally disabled children. Additionally, we aimed to investigate the relationship between attachment behaviors and clinical variables, such as age, cognitive development, severity of autism, language development, and mothers' attachment styles. METHOD: The study group consisted of 19 children with autistic disorder (mean age: 37.9 +/- 6.8 months) and the control group consisted of 18 developmentally disabled children without autistic disorder that were matched with respect to age, gender, and cognitive development. The Childhood Autism Rating Scale (CARS) was administered to all the children by two child psychiatrists. Mothers completed the Relationships Scale Questionnaire (RSQ). Cognitive development of the children was assessed with the Stanford-Binet intelligence scale. Attachment behaviors of the children were evaluated with a modified Strange Situation Procedure (SSP). RESULTS: Attachment behaviors in the children with autistic disorder and in the children with developmental disabilities were similar. In contrast to the developmentally disabled group, the children with autistic disorder stayed closer toward their mothers compared with their responses to strangers. In the autistic disorder group, attachment behaviors were not associated with age, intelligence quotient, or mothers' attachment styles; however, a significant relationship between the severity of autism and the presence of speech was observed. CONCLUSION: Parents' understanding of the attachment needs and the attachment behaviors of their autistic children in the early stages of the disorder may lead to more secure attachment relationships and improved social development.

[Childhood Traumas, Attachment and Alexithymia in Adolescentswith Psychogenic Nonepileptic Seizure Type of Conversion Disorder]. / Psikojenik Nöbet Tipinde Konversiyon Bozuklugu Olan Ergenlerde Çocukluk Çagi Travmalari, Baglanma ve Aleksitimi.

OBJECTIVE: In this cross-sectional study, childhood traumas, attachment security and alexithymia in adolescents with psychogenic nonepileptic seizures (PNES) were compared with those of adolescents without any psychiatric disorder using both semi-structured clinical interviews and self-report scales. METHOD: This study included 42 adolescents with PNES aged between 12-18 and 38 healthy adolescents who were matched with the study group in respect to socio-demographic variables. All adolescents and their parents were interviewed using Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version in order to evaluate psychiatric disorders. Clinician- Administered Posttraumatic Stress Disorder (PTSD) Scale for Children and Adolescents was used to examine the presence of PTSD symptoms. All adolescents completed the Childhood Trauma Questionnaire-28, Short Form of Inventory of Parent and Peer Attachment, Toronto Alexithymia Scale and Rosenberg Self Esteem Scale. RESULTS: Adolescents with PNES had more emotional and sexual traumatic experiences and PTSD symptoms compared to the control group. PNES group perceived higher "communication" but lower "trust" in attachment relationships with their mothers and fathers. Higher alexithymia and lower self-esteem were determined in the PNES group. Childhood traumas, lifetime PTSD symptoms and alexithymia were found to be significant risk factors for PNES in adolescents. CONCLUSION: Results indicate that comorbid psychiatric disorders, traumatic experiences, attachment problems and alexithymia need to be evaluated and treated in adolescents with PNES.

[Reliability and Validity of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, DSM-5 November 2016-Turkish Adaptation (K-SADS-PL-DSM-5-T)]. / Okul Çagi Çocuklari için Duygulanim Bozukluklari ve Sizofreni Görüsme Çizelgesi–Simdi ve Yasam Boyu Sekli–DSM–5 Kasim 2016 –Türkçe Uyarlamasinin (ÇDSG–SY–DSM–5–T) Geçerlik ve Güvenirligi.

OBJECTIVE: The aim of this study was to evaluate the reliability and validity of the Schedule for Affective Disorders and Schizophrenia for School-Age ChildrenPresent and Lifetime Version, DSM-5 November 2016 -Turkish Adaptation (K-SADS-PL-DSM-5-T).  METHOD: A total of 150 children and adolescents between 6 and 17 years of age were assessed with K-SADS-PL-DSM-5-T. The degree of agreement between the DSM-5 criteria diagnoses and the K-SADS-PL-DSM-5-T diagnoses were considered as the measure of consensus validity. In addition, concurrent validity was examined by analyzing the correlation between the diagnoses on K-SADS-PL-DSM-5-T and relevant scales. Interrater reliabilities were assessed on randomly selected 20 participants. Likewise, randomly selected 20 other participants were interviewed with K-SADS-PL-DSM-5-T three weeks after the first interview to evaluate test-retest reliability.  RESULTS: The consistency of diagnoses was almost perfect for eating disorders, selective mutism and autism spectrum disorder (κ=0.92-1.0), substantial for elimination disorders, obsessive-compulsive disorder, oppositional defiant disorder, generalized anxiety disorder, social anxiety disorder, depressive disorders, disruptive mood dysregulation disorder and attention deficit hyperactivity disorder (κ=0.67-0.80). Interrater reliability was perfect for selective mutism (κ=1.0), substantial for oppositional defiant disorder, disruptive mood dysregulation disorder, attention deficit hyperactivity disorder, depressive disorders and social anxiety disorder (κ=0.63-0.73). Test-retest reliability was almost perfect for autism spectrum disorder (κ=0.82), substantial for attention deficit hyperactivity disorder, oppositional defiant disorder, disruptive mood dysregulation disorder, depressive disorders and generalized anxiety disorder (κ=0.62-0.78).  CONCLUSION: The results of this study show that the K-SADS-PL-DSM-5-T is an effective instrument for diagnosing major childhood psychiatric disorders including selective mutism, disruptive mood dysregulation disorder and autism spectrum disorder which have recently been added to the schedule.
