RESUMEN
Childhood maltreatment (CM) is a risk factor for substance use disorders (SUD) in adulthood. Understanding the mechanisms by which people are susceptible or resilient to developing SUD after exposure to CM is important for improving intervention. This case-control study investigated the impact of prospectively assessed CM on biomarkers of endocannabinoid function and emotion regulation in relation to the susceptibility or resilience to developing SUD. Four groups were defined across the dimensions of CM and lifetime SUD (N = 101 in total). After screening, participants completed two experimental sessions on separate days, aimed at assessing the behavioral, physiological, and neural mechanisms involved in emotion regulation. In the first session, participants engaged in tasks assessing biochemical (i.e., cortisol, endocannabinoids), behavioral, and psychophysiological indices of stress and affective reactivity. During the second session, the behavioral and brain mechanisms associated with emotion regulation and negative affect were investigated using magnetic resonance imaging. CM-exposed adults who did not develop SUD, operationally defined as resilient to developing SUD, had higher peripheral levels of the endocannabinoid anandamide at baseline and during stress exposure, compared to controls. Similarly, this group had increased activity in salience and emotion regulation regions in task-based measures of emotion regulation compared to controls, and CM-exposed adults with lifetime SUD. At rest, the resilient group also showed significantly greater negative connectivity between ventromedial prefrontal cortex and anterior insula compared to controls and CM-exposed adults with lifetime SUD. Collectively, these peripheral and central findings point to mechanisms of potential resilience to developing SUD after documented CM exposure.

Childhood maltreatment is considered a risk factor for substance use disorders (SUD), but this is largely based on retrospective self-reports that are subject to recall bias, designs that do not control for familial confounding, or both. The specific contribution of childhood maltreatment to SUD risk thus remains unclear. Here, we evaluated this contribution in a prospective cohort with objectively recorded childhood maltreatment, using a design that allows controlling for familial confounding. We used medical records and registers to study 525 young adults (20-37 years) with prospectively and objectively documented severe maltreatment exposure, 1979 clinical controls (unexposed former child and adolescent psychiatry patients), 1388 matched healthy controls; and their siblings and cousins. We examined the association between maltreatment and SUD using Cox regression models in the population, as well as stratified within siblings in the same family. SUD risk was significantly increased with childhood maltreatment exposure (crude HR: 6.61, 95% CI: 5.81-7.53; HR adjusted for sex, birthyear, externalizing problems, parents' SUD and socioeconomic factors: 3.50, 95% CI 2.95, 4.16). An approximately threefold elevated SUD risk remained when comparing exposed individuals with their unexposed siblings (adjusted HR: 3.12, 95% CI 2.21, 4.42). We provide estimates of the association between childhood maltreatment and SUD accounting for possible confounds of both recall bias and familial factors. When familial confounding is controlled for, SUD risk attributable to severe childhood maltreatment is decreased, but nevertheless considerable. These findings establish a specific contribution of childhood maltreatment to SUD, underscoring the need for SUD prevention in young people exposed to maltreatment.

Preschool children's engagement/social interaction skills can be seen as aspects of positive functioning, and also act as protective aspects of functioning. On the other hand, hyperactivity/conduct problems are risk aspects that negatively affect children's everyday functioning. Few studies have investigated such orchestrated effects on mental health in young children over time. The aims of the study are first, to identify homogeneous groups of children having similar pathways in mental health between three time points. Second, to examine how children move between time points in relation to risk and protective factors. Alongitudinal study over 3 years, including 197 Swedish preschool children was used. Questionnaire data collected from preschool teachers. Statistical analysis using person-oriented methods with repeated cluster analyses. Children high in engagement/social skills and low in conduct problems continue to function well. Children with low engagement/social skills exhibiting both hyperactivity and conduct problems continue to have problems. Children with mixed patterns of protective factors and risk factors showed mixed outcomes. The stability of children's pathways was quite high if they exhibited many positive protective factors but also if they exhibited many risk factors. Children exhibiting a mixed pattern of protective and risk factors moved between clusters in a less predictable way. That stability in mental health was related to the simultaneous occurrence of either many protective factors or many risk factors supports the notion of orchestrated effects. The results indicate that early interventions need to have a dual focus, including both interventions aimed at enhancing child engagement and interventions focused on decreasing behavior problems.

Objectives: The purpose of this study was to assess the reliability and validity of Swedish translations of the Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) and Brief Illness Perception Questionnaire (B-IPQ) for use in adolescents with ADHD.Methods: Forward and backward translations of the BMQ-Specific and B-IPQ scales to Swedish were conducted and reviewed by adolescents with ADHD and professionals. The validity and reliability of both questionnaires were investigated in a cross-sectional study of 101 adolescents (13-17 years) on a long-term prescription of ADHD medication recruited from two child and adolescent psychiatric outpatient clinics in Sweden.Results: Regarding the BMQ-Specific, principal component analysis (PCA) loadings confirmed the previously defined components of Specific-Necessity and Specific-Concern. The PCA for B-IPQ revealed two components, the first one, B-IPQ Consequences, captured questions regarding perceptions of the implication of having ADHD (items 1, 2, 5, 6 and 8) and the second one, B-IPQ-Control, the perceptions of the capability to manage the ADHD disorder (items 3, 4 and 7). The Cronbach alpha coefficients for BMQ-Specific-Necessity scale was α = 0.80, for BMQ-Specific-Concern scale α = 0.75, B-IPQ Consequences α = 0.74 and for B-IPQ-Control α = 0.44.Conclusions: The present results prove the Swedish translation of BMQ-Specific and B-IPQ to be valid and reliable for utilization in adolescents with ADHD. The PCA confirmed the original components for BMQ-Specific and the recent findings of two main B-IPQ components describing emotional and cognitive implications versus the capability for self-care maintenance of ADHD.

Specific problems with time and timing that affect daily routines, homework, school work, and social relations have been recognized in children with ADHD. The primary treatments for children with ADHD do not specifically focus on time-related difficulties. The aim of this randomized controlled study (RCT) was to investigate how multimodal interventions, consisting of training in time-processing ability (TPA) and compensation with time-assistive devices (TAD), affect TPA and daily time management (DTM) in children with ADHD and time difficulties, compared with only educational intervention. Thirty-eight children on stable medication for ADHD in the 9-15-year age range were randomly allocated to an intervention or a control group. The children's TPA was measured with a structured assessment (KaTid), and the children's DTM was rated by a parent questionnaire (Time-Parent scale) and by children's self-reporting (Time-Self-rating). The intervention consisted of time-skill training and compensation with TAD. Data were analysed for differences in TPA and in DTM between the control and intervention groups in the 24-week follow-up. Children in the intervention group increased their TPA significantly (p = 0.019) more compared to the control group. The largest increase was in orientation to time. In addition, the parents in the intervention group rated their children's DTM as significantly (p = 0.01) improved compared with the parents in the control group. According to the children, their DTM was not significantly changed. In conclusion, a multimodal intervention consisting of time-skill training and TAD improved TPA and DTM in children with ADHD aged 9-15 years.

BACKGROUND: There is a high risk that young children who show early signs of mental health problems develop symptoms in the same or overlapping areas some years later. The Strengths and Difficulties Questionnaire (SDQ) is widely used to screen externalizing and internalizing problems early in life. In Sweden 80-90% of all children aged 1-5 years go to preschool and preschool is thus an appropriate context for finding early signs of mental health problems among children. METHODS: This study is part of a longitudinal project too investigate the frequency of emotional and behavioural problems for children between 1 and 5 years of age in Sweden. The SDQ including the impairment supplement questions were rated by preschool teachers too establish Swedish norms for SDQ in preschool children. RESULTS: The sample involved 815 children with a mean age of 42 months (SD = 16, range 13-71 months). 195 children were followed longitudinally for three years. There were significant differences between boys and girls on all subscales except for the Emotional subscale. The prevalence of behavioural problems was similar to other that in European countries, except for Prosocial behaviour, which was rated lower, and Conduct problems, rated higher. Swedish children were estimated to have more problems in the preschool setting, scored by preschool teachers. The development of behaviour over time differed for the different subscales of SDQ. CONCLUSIONS: The teacher version of the SDQ, for 2-4 year-olds, can be used as a screening instrument to identify early signs of emotional distress/behavioural problems in young children. Preschool teachers seem to be able to identify children with problematic behaviour with the use of SDQ at an early age. The development of behaviour over time differs for the different subscales of SDQ. The Swedish norms for SDQ are to a large extent, similar to findings from other European countries.

Adherence to attention deficit hyperactivity disorder (ADHD) treatment is important because, when untreated, it may have serious consequences with lifelong effects. In the case of adolescents on long-term medicine prescription, more knowledge is needed regarding adherence and factors influencing adherence, which was the purpose of this study. Adolescents (n = 101) on ADHD medication ≥6 months were administrated questionnaires at a monitoring appointment: Medication Adherence Report Scale (MARS), beliefs about medicines (BMQ) and the Brief Illness Perception Questionnaire (B-IPQ). Adherence was high, the mean value was 88% of the maximum MARS score, and correlated positively with the "BMQ-necessity-concerns differential" but negatively with "BMQ-concerns" and "BMQ-side effects". Adolescents with more belief in the necessity of the medication, less concerns and less experience of side effects tended to be more adherent to medication prescription ("intentional non-adherence"), while "unintentional non-adherence" (forgetfulness) was associated with how much they perceived that their ADHD affected their lives. In a multiple regression model, the variance of MARS total (R 2 = 0.21) and "intentional non-adherence" (R 2 = 0.24) was explained by the "BMQ-necessity-concern differential" and "BMQ-experienced side effects". The variance of "unintentional non-adherence" (R 2 = 0.12) was explained by the "BMQ-necessity-concern differential" and "B-IPQ-consequences of ADHD". In conclusion, adolescents on long-term medication reported good adherence, mainly influenced by more beliefs in the necessity versus concerns of the medications, less experienced side effects and more perceived consequences of ADHD. BMQ could be useful to identify risks of low adherence, which should be counteracted by partially gender-specific interventions.

BACKGROUND: In Sweden, 80-90% of children aged 1-5 years attend preschool, and that environment is well suited to identify behaviours that may be signs of mental health problems. The Strengths and Difficulties Questionnaire (SDQ) is a well-known short and structured instrument measuring child behaviours that indicate mental health problems well suited for preschool use. AIM: To investigate whether SDQ is a reliable and valid instrument for identifying behavioural problems in children aged 1-3 years and 4-5 years in a Swedish population, as rated by preschool teachers. METHODS: Preschools situated in different sized municipalities in Sweden participated. The preschool teacher rated each individual child. Concurrent validity was tested using the Child-Teacher Report Form (C-TRF) and Child Engagement Questionnaire (CEQ). Exploratory factor analysis was conducted for age groups, 1-3 years and 4-5 years. RESULTS: The preschool teachers considered most of the SDQ items relevant and possible to rate. For the children aged 1-3 years, the subscales 'Hyperactivity' (Cronbach alpha = 0.84, split half = 0.73) and 'Conduct' (Cronbach alpha = 0.76, split half = 0.80) were considered to be valid. For the age group 4-5 years, the whole original SDQ scale, 4-factor solution was used and showed reasonable validity (Cronbach alpha = 0.83, split half = 0.87). CONCLUSION: SDQ can be used in a preschool setting by preschool teachers as a valid instrument for identifying externalizing behavioural problems (hyperactivity and conduct problems) in young children. CLINICAL IMPLICATIONS: SDQ could be used to identify preschool children at high-risk for mental health problems later in life.

Psychiatric disorders are multi-factorial and their symptoms overlap. Constitutional and environmental factors influence each other, and this contributes to risk and resilience in mental ill-health. We investigated functional genetic variation of stress responsiveness, assessed as FKBP5 genotype, in relation to early life adversity and mental health in two samples of adolescents. One population-based sample of 909 12-year-old adolescents was assessed using the Life Incidence of Traumatic Events scale and the Strengths and Difficulties Questionnaire. One sample of 398 17-year-old adolescents, enriched for poly-victimized individuals (USSS), was assessed using the Juvenile Victimization Questionnaire and the Trauma Symptom Checklist for Children (TSCC). The FKBP5 rs1360780 and rs3800373 polymorphisms were genotyped using a fluorescence-based competitive allele-specific PCR. Most prominently among poly-victimized older male adolescents, the least common alleles of the polymorphisms, in interaction with adverse life events, were associated with psychiatric symptoms, after controlling for ethno-socio-economic factors. The interaction effect between rs3800373 and adverse life events on the TSCC sub-scales-anxiety, depression, anger, and dissociation-and with the rs1360780 on dissociation in the USSS cohort remained significant after Bonferroni correction. This pattern of association is in line with the findings of clinical and neuroimaging studies, and implies interactive effects of FKBP5 polymorphisms and early life environment on several psychiatric symptoms. These correlates add up to provide constructs that are relevant to several psychiatric symptoms, and to identify early predictors of mental ill-health.

The aim of this study is to demonstrate how parents of children who are victims of sexual assault experience the legal process from the children's and parents' perspective. Nine parents, identified in the records of three public prosecution offices in three cities in Sweden, were interviewed. The parents described feelings of shame and guilt over what their children had experienced. They felt stigmatized and had difficulty fulfilling their parental role, perceived a lack of information and support from the professionals involved, and experienced a sense of withdrawal from their role as parents, though they felt the professionals who worked with their children were helpful and influential.

BACKGROUND: The practice of joint physical custody, where children spend equal time in each parent's home after they separate, is increasing in many countries. It is particularly common in Sweden, where this custody arrangement applies to 30 per cent of children with separated parents. The aim of this study was to examine children's health-related quality of life after parental separation, by comparing children living with both parents in nuclear families to those living in joint physical custody and other forms of domestic arrangements. METHODS: Data from a national Swedish classroom study of 164,580 children aged 12 and 15-years-old were analysed by two-level linear regression modelling. Z-scores were used to equalise scales for ten dimensions of wellbeing from the KIDSCREEN-52 and the KIDSCREEN-10 Index and analysed for children in joint physical custody in comparison with children living in nuclear families and mostly or only with one parent. RESULTS: Living in a nuclear family was positively associated with almost all aspects of wellbeing in comparison to children with separated parents. Children in joint physical custody experienced more positive outcomes, in terms of subjective wellbeing, family life and peer relations, than children living mostly or only with one parent. For the 12-year-olds, beta coefficients for moods and emotions ranged from -0.20 to -0.33 and peer relations from -0.11 to -0.20 for children in joint physical custody and living mostly or only with one parent. The corresponding estimates for the 15-year-olds varied from -0.08 to -0.28 and from -0.03 to -0.13 on these subscales. The 15-year-olds in joint physical custody were more likely than the 12-year-olds to report similar wellbeing levels on most outcomes to the children in nuclear families. CONCLUSIONS: Children who spent equal time living with both parents after a separation reported better wellbeing than children in predominantly single parent care. This was particularly true for the 15-year-olds, while the reported wellbeing of 12-years-olds was less satisfactory. There is a need for further studies that can account for the pre and post separation context of individual families and the wellbeing of younger age groups in joint physical custody.

BACKGROUND: The aim of this study was to investigate the impact of migrant density in school on the well-being of pupils with a migrant origin in first as well as second generation. METHODS: Cross-sectional analysis of data from a national classroom survey of 15-year-old Swedish schoolchildren. The study population included 76 229 pupils (86.5% participation) with complete data set from 1352 schools. Six dimensions of well-being from the KIDSCREEN were analysed in two-level linear regression models to assess the influence of migrant origin at individual level and percentage of students with a migrant origin at school level, as well as interaction terms between them. Z-scores were used to equalize scales. RESULTS: A high density (>50%) of pupils with a migrant origin in first or second generation was associated with positive well-being on all six scales for foreign-born pupils originating in Africa or Asia compared with schools with low (<10%) migrant density. The effect sizes were 0.56 for boys and 0.29 for girls on the comprehensive KIDSCREEN 10-index (P<0.001) and 0.61 and 0.34, respectively, for psychological well-being (P<0.001). Of the boys and girls born in Africa or Asia, 31.6% and 34.6%, respectively, reported being bullied during the past week in schools with low (<10%) migrant density. CONCLUSIONS: Pupils born in Africa or Asia are at high risk for being bullied and having impaired well-being in schools with few other migrant children. School interventions to improve peer relations and prevent bullying are needed to promote well-being in non-European migrant children.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) and Autism Spectrum Disorder (ASD) are often accompanied by sleep problems influencing social, emotional and cognitive functioning in everyday activities. AIM: The aim of this study was to investigate whether the use of a weighted blanket has a positive impact on sleep and everyday activities in individuals with ADHD and/or ASD. MATERIAL AND METHODS: The study included 85 individuals diagnosed with ADHD and/or ASD, 48 children aged ≤17 (57%) and 37 adults ≥18 years (44%), who were prescribed with a weighted blanket. The participants responded via a telephone interview. RESULTS: Findings demonstrated that a weighted blanket improved abilities related to falling asleep, sleeping the whole night, and relaxing during the day. Using a weighted blanket improved morning/evening daily routine, including preparing/going to sleep and waking up in the morning. CONCLUSIONS: Weighted blankets showed positive impact on falling asleep, sleeping the whole night, and relaxing during the day, and they were used frequently by children and adults with ADHD and/or ASD. Findings indicate that a weighted blanket improved morning/evening routine, however this research area needs further investigation using both subjective and objective parameters.

OBJECTIVES: Childhood maltreatment (CM), widely held as a risk factor for substance use disorders (SUDs), is commonly assessed using the Childhood Trauma Questionnaire (CTQ). Retrospective self-reports are, however, potentially subject to bias. We used a unique patient sample with prospectively documented CM to examine the performance of the CTQ and how this is affected by the presence of SUD. METHODS: Analysis was based on a total of 104 individuals. Subjects with prospectively recorded CM were identified from a specialized childhood trauma unit in Linköping, Sweden (n = 55; 31 with SUD, 61% females; 24 without SUD, 71% females). Clinical controls had SUD but no CM (n = 25, 48% females). Healthy controls had neither SUD nor CM (n = 24, 54% females). We analyzed the agreement between retrospective CTQ scores and prospectively documented CM by κ analysis and assessed the performance of the CTQ to identify CM exposure using receiver operating characteristic (ROC) analysis. RESULTS: Agreement between prospectively and retrospectively recorded CM exposure was poor for sexual abuse (36.6%, Cohen κ = 0.32, P = 0.008) and physical abuse (67.3%, κ = 0.35, P = 0.007). Overall CTQ performance was fair (ROC: area under the ROC curve = 0.78, optimal cutoff = 36.5, sensitivity = 0.65, specificity = 0.75). However, performance was excellent in the absence of SUD (area under the ROC curve = 0.93, cutoff = 32.0, sensitivity = 0.88, specificity = 0.88), but poor in participants with lifetime SUD (area under the ROC curve = 0.62, cutoff = 42.0, sensitivity = 0.60, specificity = 0.36). CONCLUSIONS: These data support the CTQ as a tool to assess CM exposure but suggest that it may be less useful in patients with SUD.

INTRODUCTION: The tactile sense plays a crucial role in the development and maintenance of a functional bodily self. The ability to differentiate between self- and nonself-generated touch contributes to the perception of the bodies' boundaries and more generally to self-other-distinction, both of which are thought be altered in anorexia nervosa (AN) and autism spectrum condition (AS). While it has been suggested that AN and AS are characterized by overlapping symptomatology, they might differ regarding body perception and self-other-distinction. METHODS: Participants with a diagnosis of AN (nâ¯=â¯25), AS (nâ¯=â¯29), and a comparison group without diagnoses (nâ¯=â¯57) performed a self-other-touch task during functional brain imaging. In the experimental conditions, they stroked their own arm or were stroked on the arm by an experimenter. RESULTS: As shown previously, the CG group showed lower activation or deactivation in response to self-touch compared to social touch from someone else. A main group effect was found in areas including somatosensory cortex, frontal and temporal gyri, insula, and subcortical regions. This was driven by increased activations in participants with AN, while participants in the AS group showed mostly comparable activations to the comparison group. CONCLUSIONS: AN diagnosis was associated with an increased neural activity in response to both self-touch and social touch. Failure to attenuate self-touch might relate to altered predictions regarding the own body and reduced perception of bodily boundaries. Participants with an AS diagnosis were mostly comparable to the comparison group, potentially indicating unaltered tactile self-other-distinction.

Pharmacokinetics of antidepressant drugs (ATDs), in terms of steady-state and trough values, in patients from Child and Adolescent Psychiatry centers in the midsouth-eastern part of Sweden, were evaluated, and the use of ATDs in this population were described. Patients to be prescribed an ATD were studied between 2002 and 2004. Two hundred eleven children, 64% girls and 36% boys (ages 8-20 years) were evaluated. The primary indication for the antidepressant treatment was depression in 69% of subjects. The median body mass index was 20.2 kg/m² (range, 12.4-38.6 kg/m²). Suspected adverse drug reactions were spontaneously reported in 31% (no serious). Monotherapy was indicated in 49% of request forms. The most common drug combination with the ATD was oral contraceptives. The concentrations of drugs in the patient evaluated population to referenced data for adults from the dose administered were as expected in 63%, higher than expected in 26% and lower than expected in 11%. The most prescribed ATD was sertraline (SERT). Dose-concentration relationships for SERT and metabolite desmethylsertraline (DSERT) were seen, rs = 0.48 and rs = 0.5, respectively. No relationship was found between dose and ratio DSERT/SERT. The median daily dose was 50 mg (range, 12.5-150 mg), SERT concentration 16 ng/mL (range, 3-88 ng/mL), and DSERT 33 ng/mL (range, 0-253 ng/mL). CYP2D6*4 was the most common poor metabolizer allele. Therapeutic drug monitoring may provide support to prescribing physicians to individual dose optimizing and to assess drug compliance, above all when ATDs are not well studied in pediatric patients before approval for general prescription.

BACKGROUND: The normal development of cortisol regulation during childhood is thought to be influenced by a complex interplay between environmental and genetic factors. METHOD: The aim of this study was to estimate genetic and environmental influences on basal cortisol levels in a sample of 151 twin pairs aged 9-16 years. Salivary cortisol was collected on two consecutive days when the children attended school--immediately after awakening, 30 min post-awakening and at bedtime. RESULTS: Heritability was highest (60%) for cortisol levels about 30 min after awakening. For samples taken immediately at awakening heritability was less pronounced (28%) and in the evening low (8%). CONCLUSION: The limited genetic influence on evening levels, moderate on cortisol at awakening and high on awakening response, might imply two genetic regulation patterns, one specifically for awakening response and one for the circadian rhythm proper. These findings could explain divergent results in previous studies and highlight the importance of taking the circadian rhythm into account in studies of cortisol levels in children.

BACKGROUND: Children with attention deficit hyperactivity disorder (ADHD) have difficulties with occupational performance, related to difficulties with time-processing ability. AIMS: To examine the outcome of a multimodal time-related intervention designed to support children aged 9-15 years with ADHD, to achieve their occupational performance goals and improve satisfaction with occupational performance. A further aim was to compare the children's ratings of outcome with their parents' ratings and to analyse the occupational performance goals. MATERIAL AND METHODS: A pre-post design was used. Participants were 27 children, aged 9-15 years. Children and parents rated occupational performance and satisfaction at baseline and follow-up, after 24 weeks, using the Canadian Occupational Performance Measure (COPM). The intervention consisted of time-skills training and time-assistive devices (TADs). Descriptive and non-parametric statistics were used. RESULTS: Significant improvements were found in reported performance and satisfaction. Children's were higher than those of their parents. Most goals were about carrying out daily routines, knowing the duration of an activity and knowing what will happen in the near future. CONCLUSION AND SIGNIFICANCE: The study contributes to knowledge about suitable interventions for children with ADHD who have time-related difficulties. Occupational therapy interventions, including TADs and time-skills training, resulted in significantly improved occupational performance.

BACKGROUND: Nonsuicidal self-injury (NSSI) is prevalent in adolescent populations worldwide. Emotion dysregulation is believed to contribute to NSSI, but underlying mechanisms are less known. We combined psychophysiological and neural data with subjective self-report in close temporal proximity to examine the mechanisms underlying emotion processing in adolescents with NSSI relative to control adolescents without a psychiatric diagnosis. METHODS: Thirty female adolescents with NSSI and 30 age-matched female control subjects were included in this case-control study. Participants were presented with negative affective pictures during a functional magnetic resonance imaging scan. In a separate facial electromyography session, the same participants were shown positive and negative affective images and also provided ratings of valence and arousal. RESULTS: Participants with NSSI responded to affective images with greater positive (e.g., zygomatic) and greater negative (e.g., corrugator) reactivity. We found no differences in self-reported affect in response to the images. Analyses of the negative picture-viewing functional magnetic resonance imaging data showed a significant positive correlation between anterior insula response and the averaged electromyography magnitude in NSSI, but not in control subjects. CONCLUSIONS: Adolescents with NSSI show enhanced emotional reactivity that is associated with anterior insula responding, but no abnormalities in self-reported affect. This discrepancy between self-report and objective measures of emotional reactivity potentially indicates a suppression of the emotional reaction in adolescents with NSSI. Moreover, the current data suggest potential targets for novel therapeutic approaches that can be combined with existing clinical treatment, such as real-time electromyography-based biofeedback focusing on emotional awareness, labeling, and expressing emotional experiences.
