Does Involvement in Peer Bullying Invite Self-Injury?: The Association Between Peer Bullying and Self-Injury in a Clinical Sample.

ABSTRACT: Previous studies have linked peer bullying to nonsuicidal self-injury (NSSI). However, the evidence is largely limited to population-based groups. This study examined whether there is a relationship between NSSI and being a victim of peer bullying among adolescents in a clinical sample and how this may be influenced by types of bullying. The sample consisted of 96 outpatients with NSSI and 107 healthy adolescents. The Inventory of Statements About Self-Injury, Peer Bullying Scale, and Rosenberg Self-Esteem Scale were applied. Whereas the scores of each bullying type of adolescents with NSSI were significantly higher, their self-esteem scores were significantly lower. Each victimization score of bullying had a negative correlation with NSSI-onset age and self-esteem scores and a positive correlation with self-injury scores. This study demonstrated that being a victim of any type of bullying is strongly associated with self-injury. It would be advisable to screen adolescents with self-injury for exposure to bullying, and vice versa.

Clinical characteristics according to sex and symptom severity in children with selective mutism: a four-center study.

INTRODUCTION: Clinical information regarding selective mutism (SM), a persistent and debilitating psychiatric disorder, in children is extremely limited. We aimed to examine sociodemographic characteristics and comorbid psychiatric conditions and identify clinical variables associated with sex and SM severity among children with SM. METHODS: We analyzed the medical records of 49 children who received treatment for SM in four different tertiary hospitals in Turkey between 2016 and 2021. Children's charts were reviewed to examine clinical characteristics, comorbidities, and response to treatment. RESULTS: Thirty-one children were female, and 18 were male (female:male ratio is 1.7:1). Most children (73.5%) with SM displayed onset of SM in 3-6 years. However, most children (57.1%) were diagnosed between the ages of 7-11. The mean time from onset to diagnosis was 1.69 ± 1.37 years. Females displayed a later onset of SM (6.42 ± 2.40 vs. 4.89 ± 0.96; p= 0.013) and higher comorbidity rates (71% vs. 38.9%, p= 0.039) than males. The vast majority of children received two or more psychiatric diagnoses. Children in the severe group had a longer duration of illness, higher rates of psychiatric comorbidity, speech delay, and treatment resistance. CONCLUSION: Our study suggests that SM may have different clinical features according to sex and symptom severity of SM. More information about children with SM is needed to understand the development and maintenance of SM.

Sociodemographic variables, clinical characteristics, and treatments in children with trichotillomania in terms of age and gender: a multicenter study.

OBJECTIVE: Although trichotillomania (TTM) is a common, typically pediatric-onset disorder, data on the phenomenology of TTM in children, accompanying comorbid psychiatric disorders, and treatment options are extremely limited. In our study, it was aimed to investigate these variables and related factors in patients undergoing psychiatric evaluation and follow-up. METHOD: The study included 79 children and adolescents between the ages of 4 and 17 who were diagnosed with TTM and followed up in four different Child and Adolescent Psychiatry outpatient clinics between 2015 and 2020. The sociodemographic characteristics of these patients, clinical features of the disease, comorbid psychiatric disorders, and treatment approaches have been studied. RESULTS: Our results showed that TTM was more common in girls, hair and eyebrow plucking was the most common, and symptoms and features accompanying TTM changed with age, but not with gender. Again, 79.7% of these children had at least one psychiatric comorbid disorder (most common being anxiety disorders and Attention Deficit/Hyperactivity Disorder), comorbidity was closely related to TTM severity, 93.7% used at least one pharmacotherapeutic agent, and positive response rates to treatment were found to be low. Moreover, TTM severity was found to increase with age and disease duration. CONCLUSION: Study findings support that clinical presentation, disease severity and comorbidity rates may change with age in children and adolescents with TTM, and early intervention is important to prevent clinical progression/worsening and mental health sequela.
