The link between peer relations, prosocial behavior, and ODD/ADHD symptoms in 7–9-Year-Old Children

Oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) are characterized by symptoms that hinder successful positive interaction with peers. The main goal of this study was to examine if the presence of symptoms of ODD and ADHD affects the relationship between positive social behavior and peer status found in 7–9-year-old children who show symptoms typical of ADHD and/or ODD. Furthermore, the possible interaction with sex was investigated. We used data collected in the first wave of The Bergen Child Study of mental health (BCS), a prospective longitudinal total population study of children’s developmental and mental health. The target population consisted of children in the second to the fourth, in all public, private, and special schools in Bergen, Norway, in the fall of 2002 (). All 79 primary schools in Bergen participated in the study. Both teacher (8809 complete cases) and parent (6253 complete cases) report were used in the analyses. ADHD and ODD scores were estimated using the Swanson Noland and Pelham rating scale version IV (SNAP-IV), and peer problems and prosocial behavior were assessed using the Strengths and Difficulties Questionnaire (SDQ). We replicated the relationship between peer problems and prosocial behavior found previously in typically developing children. Our results showed that the relationship between peer problems and prosocial behavior became weaker as the ODD symptoms increased in number and severity. For ADHD this effect was only found in the teacher report of the children. A sex effect for ODD symptoms was found only using the parent report: boys with ODD symptoms showed less prosocial behavior than girls with similar levels of ODD symptoms. Since this effect was not found using the teacher data, it may imply a situational effect (school/home) for girls with high levels of ODD. The moderator effect of ODD/ADHD was comparable for boys and girls. Our findings suggest that even if children with ADHD/ODD symptoms have the opportunity to practice their social skills in peer relationships, this is not necessarily accompanied by an increase in prosocial behavio

A study of the dimensionality and measurement precision of the SCL-90-R

We used item response theory (IRT) to (a) investigate the dimensionality of the Symptom Checklist-90-Revised (SCL-90-R) in a severely disturbed patient group, (b) improve the subscales in a meaningful way and (c) investigate the measurement precision of the improved scales. The total sample comprised 3078 patients (72% women, mean age = 35 ± 9) admitted to 14 different day hospitals participating in the Norwegian Network of Personality-focused Treatment Programmes. Mokken Scale Analysis was used to investigate the dimensionality of the SCL-90-R and improve the subscales. This analysis was theory-driven: the scales were built on two start items that reflected the content of the disorder that corresponds with the specific scale. The Graded Response Model was employed to determine measurement precision. Our theory-driven IRT approach resulted in a new seven-factor solution including 60 of the 90 items clustered in seven scales: depression, agoraphobia, physical complaints, obsessive-compulsive, hostility (unchanged), distrust and psychoticism. Most of the new scales discriminated reliably between patients with moderately low scores to moderately high scores. In conclusion, we found support for the multidimensionality of the SCL-90-R in a large sample of severely disturbed patients

Psychiatric characteristics in transsexual individuals: multicentre study in four European countries

Background Research into the relationship between gender identity disorder and psychiatric problems has shown contradictory results. Aims To investigate psychiatric problems in adults fulfilling DSM-IV-TR criteria for a diagnosis of gender identity disorder. Method Data were collected within the European Network for the Investigation of Gender Incongruence using the Mini International Neuropsychiatric Interview - Plus and the Structured Clinical Interview for DSM-IV Axis II Disorders (n = 305). Results In 38% of the individuals with gender identity disorder a current DSM-IV-TR Axis I diagnosis was found, mainly affective disorders and anxiety disorders. Furthermore, almost 70% had a current and lifetime diagnosis. All four countries showed a similar prevalence, except for affective and anxiety disorders, and no difference was found between individuals with early-onset and late-onset disorder. An Axis II diagnosis was found in 15% of all individuals with gender identity disorder, which is comparable to the general population. Conclusions People with gender identity disorder show more psychiatric problems than the general population; mostly affective and anxiety problems are foun

Recalled gender-related play behavior and peer-group preferences in childhood and adolescence among adults applying for gender-affirming treatment

Norms are considered to influence expectations toward gender-related behavior. Deviations from these norms are often perceived negatively by the social environment. The objective of this study was to investigate adults diagnosed with a Gender Identity Disorder (GID), their recalled play behavior, and peer preferences in childhood and adolescence. Differences between individuals who applied for transition from female to male (FtMs) and those who applied for transition from male to female (MtFs) and between age-of-onset subgroups were explored. Data collection took place as part of the European Network for the Investigation of Gender Incongruence. The sample consisted of N = 634 participants (mean age = 30.6) diagnosed with GID according to DSM-IV-TR who were recruited between 2007 and 2012. Participants answered two questions regarding recalled play behavior and three questions on peer preferences. Nonconforming gender expression was more frequently recalled in FtMs than MtFs. Within gender groups, individuals who were categorized as early-onset recalled nonconforming gender expression more frequently than individuals who were categorized as late-onset. The results of the study are in line with previous findings indicating different phenomenological pathways in individuals applying for gender-affirming treatment that warrant attention. Factors that are considered to impact on gender-related differences in nonconforming gender expression are discussed

Body image in young gender dysphoric adults : a European multi-center study

The alteration of sex-specific body features and the establishment of a satisfactory body image are known to be particularly relevant for individuals with Gender Dysphoria (GD). The aim of the study was to first develop new scales and examine the psychometric properties of the Hamburg Body Drawing Scale (Appelt & Strau 1988). For the second part of this study, the satisfaction with different body features in young GD adults before cross-sex treatment were compared to female and male controls. Data collection took place within the context of the European Network for the Investigation of Gender Incongruence (ENIGI) including 135 female-to-male (FtMs) and 115 male-to-female (MtFs) young GD adults and 235 female and 379 male age-adjusted controls. The five female and six male body feature subscales revealed good internal consistency. The ENIGI sample reported less satisfaction with overall appearance (d = 0.30) and with all of their body features than controls, but no subgroup differences for sexual orientation (FtM and MtF) and Age of Onset (FtM) were found. Body dissatisfaction was higher with regard to sex-specific body features (largest effect sizes of d = 3.21 for Genitalia in FtMs and d = 2.85 for Androgen-responsive features and genitalia in MtFs) than with those that appeared less related to the natal sex (d = 0.64 for Facial features in FtMs and d = 0.59 for Body shape in MtFs). Not only medical body modifying interventions, but also psychosocial guidance with regard to body image might be helpful for GD individuals before transitioning
