Drug survival and risk factors for ADHD medication discontinuation in adults: A Danish Nationwide Registry-based cohort study.

INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) medication has proven effective for treating ADHD in adults, nonetheless previous studies have shown high rates of medication discontinuation. OBJECTIVE: To assess drug survival and identify risk factors associated with discontinuation of ADHD medication. METHODS: A nationwide registry-based cohort study in Danish adults who redeemed a prescription for ADHD medication for the first time between 2010 and 2015. All patients were followed for 5 years from the first redeemed prescription. Discontinuation was defined as a gap of 12 months between redemptions. Logistic regression analysis with odds ratio (OR) and Kaplan Meier analysis were used to examine risk factors (sex, age, socioeconomic status, substance use disorders, and comorbidities) associated with discontinuation. RESULTS: Twenty three thousand nine-hundred and sixteen patients with ADHD were identified. The 5-year overall drug survival was 29% in women vs. 23.5% in men. The risk of medication discontinuation was significantly higher in men compared to women, OR 1.26 (95% CI 1.19-1.34, p < 0.001). Adults aged 31-50 years had a significantly decreased risk of medication discontinuation compared to adults aged 18-30 years, OR 0.57 (95% CI 0.53-0.61, p < 0.001). Switching ADHD medication two times or three times or more significantly decreased the risk of discontinuation; OR 0.53 (95% CI 0.49-0.56, p < 0.001) and OR 0.26 (95% CI 0.23-0.30, p < 0.001), respectively. Substance use disorders and certain comorbidities were associated with medication discontinuation. Eating disorders, OR 0.71 (95% CI 0.64-0.78, p < 0.001), intellectual disabilities, OR 0.65 (95% CI 0.59-0.73, p < 0.001) and sleep disorders, OR 0.42 (95% CI 0.37-0.49, p < 0.001) were associated with continuation of ADHD medication. CONCLUSIONS: The 5-year overall drug survival was longer in women compared to men. Women with ADHD; adults aged 31-50; and patients with comorbid eating disorder; intellectual disability; sleep disorder and medication switching were individually associated with continuation of ADHD medication. Various factors were associated with medication discontinuation. Discontinuation should be acknowledged as a common phenomenon in patients with ADHD and calls for increased attention from the treatment responsible prescriber or team. Moreover, our findings suggest that timely, frequent medication switching, or temporary regimens may indeed represent optimal management strategies for a significant proportion of the ADHD population.

Exploring latent clusters in pediatric OCD based on symptoms, severity, age, gender, and comorbidity.

Given diverse symptom expression and high rates of comorbid conditions, the present study explored underlying commonalities among OCD-affected children and adolescents to better conceptualize disorder presentation and associated features. Data from 830 OCD-affected participants presenting to OCD specialty centers was aggregated. Dependent mixture modeling was used to examine latent clusters based on their age- and gender adjusted symptom severity (as measured by the Children's Yale-Brown Obsessive-Compulsive Scale; CY-BOCS), symptom type (as measured by factor scores calculated from the CY-BOCS symptom checklist), and comorbid diagnoses (as assessed via diagnostic interviews). Fit statistics favored a four-cluster model with groups distinguished primarily by symptom expression and comorbidity type. Fit indices for 3-7 cluster models were only marginally different and characteristics of the clusters remained largely stable between solutions with small clusters of distinct presentations added in more complex models. Rather than identifying a single classification system, the findings support the utility of integrating dimensional, developmental, and transdiagnostic information in the conceptualization of OCD-affected children and adolescents. Identified clusters point to the centrality of contamination concerns to OCD, relationships between broader symptom expression and higher levels of comorbidity, and the potential for complex/neurodevelopmental presentations.

Cannabinoids as alleviating treatment for core symptoms of autism spectrum disorder in children and adolescents: a systematic review.

INTRODUCTION: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder affecting about 1% of children. The disorder is characterized by difficulties within three core symptoms: social interactions, communication, and restricted or repetitive behavior. There is currently no approved psychopharmacological treatment; however, it is hypothesized that ASD symptoms might be ameliorated by manipulating the endocannabinoid (eCB) system.This study aims to review the existing research on cannabinoids as a potential effective treatment for the core symptoms of ASD in children and adolescents. METHODS: A literature search was conducted on PubMed, Embase, APA PsychInfo, and Cochrane. The available literature was screened, and studies were included if: the study population consisted of children/adolescents, the treatment involved cannabinoids, and the outcome assessed was the impact on core ASD symptoms. RESULTS: The search yielded five studies, two RCTs and three cohort studies. All the included studies reported an effect of the cannabinoid treatment; however, most of these effects were non-significant and not related to core symptoms. Only one study found a significant improvement on all three core symptoms. The risk of bias was rated as "high" or "very high" in four studies and as "low" in one study. DISCUSSION: Although the included studies did not find substantial results regarding core ASD symptoms, they all reported that cannabinoid treatment had other positive effects. However, Long term outcome is unknown, and safety aspects are scarcely discussed. CONCLUSION: Based on this review, the effect of cannabinoid treatment on ASD core symptoms is not clear; therefore, further studies are required.

Testing a cognitive behavioural therapy program for anxiety in autistic adolescents: a feasibility study.

BACKGROUND: Autism includes core symptoms affecting general and social development. Up to 60% of autistic adolescents experience co-occurring anxiety disorders negatively influencing educational, social, and general development together with quality of life. A manualised cognitive behavioural therapy (CBT) program 'Cool Kids - Autism Spectrum Adaptation (ASA)' has previously demonstrated efficacy in reducing anxiety in children with co-occurring autism. The current study investigates the feasibility of adapting this program for adolescents. METHODS: Fifteen autistic adolescents, aged 14-17 years, with co-occurring anxiety disorders were enrolled in the study. Outcome measures collected from both adolescents and parents pre-, post-treatment and at 3-month follow-up included participant evaluation of the program, scores from a semi-structured anxiety interview, and questionnaires on anxiety symptoms, life interference, and quality of life. RESULTS: 92% of the families who completed the program found it useful and would recommend it to other families in a similar situation. At follow-up, 55% no longer met the criteria for their primary anxiety diagnosis and 34% of adolescents were free of all anxiety diagnoses. Of the five adolescents who did not attend school before treatment three (60%) had returned to school after treatment. CONCLUSION: This study suggests that the adaptation of the program 'Cool Kids - ASA' into an adolescent version is feasible and has the potential to show good effects thus enhancing the possibility of education, development and independence in future life for this group. Larger RCTs studies are, however, needed to examine the efficacy of the adolescent version.

One year follow-up of participants in a randomised controlled trial of a CBT-based group therapy programme for adolescents diagnosed with ADHD.

BACKGROUND: Adolescents with ADHD often struggle on many areas of their lives and have a high risk of adverse outcomes and negative life trajectories. Multimodal treatment including psychosocial interventions is recommended but evidence regarding effect of such interventions is still limited. MATERIALS AND METHODS: This study was a follow-up study of adolescents participating in a randomised controlled trial (RCT) of a group intervention based on cognitive behavioural therapy (CBT). Participants were adolescents diagnosed with ADHD and still impaired by their symptoms after standard treatment including psychoeducation and medication. All participants were interviewed by telephone one year after inclusion, and outcome measures included both quantitative and qualitative measures. RESULTS: There were 100 adolescents included in the study. We found no significant differences between treatment and control group on measures of ADHD-symptoms, self-efficacy, overall problems, global psychosocial functioning, or symptom severity at one-year follow-up. Still, participants in the intervention group reported on positive gains and that they learned a lot about ADHD and themselves. CONCLUSIONS: The intervention delivered in this trial failed to show a treatment effect on symptom level when added to standard care. Participants did however report on positive gains and felt they learned a lot. More research is needed to explore how the programme and delivery of treatment might be improved, and which patients might benefit the most from this type of interventions.

Prevalence of chronic and multisite pain in adolescents and young adults with ADHD: a comparative study between clinical and general population samples (the HUNT study).

Attention-deficit/hyperactivity disorder (ADHD) and chronic pain are prevalent and associated. We examined the prevalence and distribution of chronic pain in adolescents and young adults with ADHD using 9-years longitudinal data (from T1:2009-2011 to T3:2018-2019) with three time points from a clinical health survey compared to two age-matched reference population-based samples. Mixed-effect logistic regression and binary linear regression were used to estimate the probability for chronic and multisite pain at each time point and to compare the prevalence of chronic pain with the reference populations. The prevalence of chronic and multisite pain was high in those with ADHD, especially in female young adults, with highly prevalent chronic pain at 9 years of follow-up (75.9%) compared to 45.7% in females in the reference population. The probability of having pain was only statistically significant for chronic pain in males at 3 years of follow-up (41.9%, p = 0.021). Those with ADHD were at higher risk of reporting single-site and multisite pain compared to the general population at all measurement points. Longitudinal studies should be tailored to further understand the complex sex differences of comorbid chronic pain and ADHD in adolescents, exploring predictive factors of pain assessing long-term associations with bodyweight, psychiatric comorbidities, and possible mechanisms of stimulant use effects on pain.

Functional somatic symptoms in preschool attention-deficit/hyperactivity disorder: a secondary analysis of data from a randomized controlled trial of parent training.

Children with attention-deficit/hyperactivity disorder (ADHD) can be more stress-vulnerable, and thereby, it has been suggested, prone to develop functional somatic symptoms (FSS) compared to their peers. In this paper, using data from 160 children aged 3-7 years with ADHD from the D'SNAPP study, a randomized controlled trial testing a parent training intervention, we addressed a number of questions about the role of FSS in ADHD. First, are FSS levels higher in an ADHD sample than in the children of the general population. Second, do FSS levels predict psychopathology and health-related quality of life (HRQoL) in ADHD samples. Third, does FSS levels moderate the effect of parent training on ADHD symptoms. We found that preschoolers with ADHD experienced more severe FSS than a general population-based sample (18.80% vs. 2.11%). Severe FSS were associated with increased psychopathology and impaired daily function and lower HRQoL. Level of baseline FSS did not moderate the effect of parent training on ADHD. FSS in preschool children with ADHD is associated with impaired daily functioning, but further research is warranted to determine the clinical impact of FSS in children with ADHD.

Body Dysmorphic Symptoms in Youth with Obsessive-compulsive Disorder: Prevalence, Clinical Correlates, and Cognitive Behavioral Therapy Outcome.

The aims of the study were to estimate the prevalence of body dysmorphic symptoms in a sample of children and adolescents with obsessive-compulsive disorder, possible clinical correlates and whether BDD symptoms predict poorer treatment outcomes after cognitive behavioral therapy. The study included 269 children and adolescents with OCD, aged 7-17 years, from Denmark, Sweden, and Norway, who were treated with 14 weekly sessions of manualized, exposure-based CBT. Twenty-one patients (7.8%) had BDD symptoms. BDD symptoms were associated with older age (p = 0.003) and a higher prevalence of comorbid anxiety disorders (p = 0.025). In addition, patients with BDD symptoms endorsed a greater number of OCD symptoms than did those without BDD symptoms. Having symptoms of BDD did not affect the CBT outcome on OCD. The results of the study suggest that CBT for OCD is equally effective for those with and without comorbid BDD symptoms.

Family Accommodation in Pediatric Obsessive-Compulsive Disorder: Investigating Prevalence and Clinical Correlates in the NordLOTS Study.

Family accommodation (FA) involves the actions taken by family members, particularly parents, to accommodate a child´s obsessive-compulsive disorder (OCD) symptoms, reducing distress or impairment. This behavior may maintain compulsive and avoidant behavior, preventing corrective learning or habituation. This study aims to investigate the prevalence and factors influencing FA in a large Scandinavian sample of children with OCD. We assessed 238 children using standardized diagnostic interviews, OCD symptom severity assessments and questionnaires evaluating functional impairment and internalizing and externalizing symptoms. FA was measured using the Family Accommodation Scale, a 12-item clinician-rated interview. Our results confirmed a high frequency of accommodation, with approximately 70% of primary caregivers reporting some accommodation daily and 98% at least once per week. FA was associated with increased OCD symptom severity, contamination/cleaning symptoms, internalizing and externalizing behavior, and functional impairment. Linear regression analysis showed that high levels of FA are specifically associated with lower age, higher OCD symptom severity, parent-reported impairment, internalizing, and externalizing symptoms. A path analysis revealed that FA partially mediated the relationship between OCD severity, externalizing symptoms, and child's age, highlighting the role of FA in the progression of OCD and related symptoms. The findings emphasize the importance of evaluating FA before initiating treatment and specifically addressing it during the therapeutic process.

How much impairment is required for ADHD? No evidence of a discrete threshold.

BACKGROUND: A diagnosis of attention-deficit/hyperactivity disorder (ADHD) requires the presence of impairment alongside symptoms above a specific frequency and severity threshold. However, the question of whether that symptom threshold represents anything more than an arbitrary cutoff on a continuum of impairment requires further empirical study. Therefore, we present the first study investigating if the relationship between ADHD symptom severity and functional impairment is nonlinear in a way that suggests a discrete, nonarbitrary symptom level threshold associated with a marked step increase in impairment. METHODS: Parent reports on the ADHD-Rating Scale (ADHD-RS-IV), the Weiss Functional Impairment Rating Scale (WFIRS-P), and the Strengths and Difficulties Questionnaire were collected in a general population sample of 1st, 2nd, and 3rd graders (N = 1,914-2,044). RESULTS: Piecewise linear regression analyses and nonlinear regression modeling both demonstrated that the relationship between symptom severity (ADHD-RS-IV total score) and impairment (WFIRS-P mean score) was characterized by a gradual linear increase in impairment with higher symptom severity and no apparent step increase or changing rate of increase in impairment at a certain high ADHD-RS-IV total score level. Controlling for socioeconomic status, sex, and co-occurring conduct and emotional symptoms did not alter these results, though comorbid symptoms had a significant effect on impairment. CONCLUSIONS: There was no clear evidence for a discrete, nonarbitrary symptom severity threshold with regard to impairment. The results highlight the continued need to consider both symptoms and impairment in the diagnosis of ADHD.

Cognitive behavioural group therapy as addition to psychoeducation and pharmacological treatment for adolescents with ADHD symptoms and related impairments: a randomised controlled trial.

BACKGROUND: Cognitive behavioural therapy (CBT) is recommended for attention-deficit/hyperactivity-disorder (ADHD) in adolescents. However, all CBTs are not created equal, and the guidelines do not specify which CBT interventions are the most effective for this patient group. This study examines the efficacy of a group CBT without parent involvement as follow-up treatment compared to no additional CBT in adolescents with persistent and impairing ADHD symptoms after a short psychoeducational intervention and medical treatment. METHODS: The authors conducted a two-arm parallel randomized controlled trial in two child and adolescent mental health outpatient clinics in Norway. One hundred patients aged 14-18 years with a diagnosis of ADHD (66%) or subthreshold ADHD (34%) were randomized to either a 12-week group CBT program (N = 50) or a non-CBT control condition (N = 50). Assessments were made at admission to the clinic, two weeks before and two weeks after treatment. The primary outcomes were parent-, teacher- and self-ratings of ADHD symptoms (ADHD Rating Scale-IV), and the secondary outcomes were ratings of ADHD symptom severity, executive function, functional impairment, and emotional problems. Evaluators blinded to group allocation rated ADHD symptom severity with the Clinical Global Impression Scale for Severity (CGI-S) at baseline and post-treatment. RESULTS: Analyses using mixed-effects models showed no difference between the treatment arms from baseline to post treatment in primary and secondary outcomes. CONCLUSIONS: Contrary to our hypothesis, we found no incremental treatment effect on the part of a group CBT as follow-up to psychoeducation and pharmacological treatment on ADHD symptoms and accompanying impairments. Limitations with the CBT was the large number and low dosage of treatment components, causing restricted time for practice. Unlike evidence-based, individualized targeted CBTs with parent involvement, a group CBT directed solely at the adolescents with no parent involvement does not appear effective for treating ADHD.

Family-based cognitive behavioural therapy versus family-based relaxation therapy for obsessive-compulsive disorder in children and adolescents: protocol for a randomised clinical trial (the TECTO trial).

BACKGROUND: Cognitive behavioural therapy (CBT) is the recommended first-line treatment for children and adolescents with obsessive-compulsive disorder (OCD), but evidence concerning treatment-specific benefits and harms compared with other interventions is limited. Furthermore, high risk-of-bias in most trials prevent firm conclusions regarding the efficacy of CBT. We investigate the benefits and harms of family-based CBT (FCBT) versus family-based psychoeducation and relaxation training (FPRT) in youth with OCD in a trial designed to reduce risk-of-bias. METHODS: This is an investigator-initiated, independently funded, single-centre, parallel group superiority randomised clinical trial (RCT). Outcome assessors, data managers, statisticians, and conclusion drawers are blinded. From child and adolescent mental health services we include patients aged 8-17 years with a primary OCD diagnosis and an entry score of ≥16 on the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). We exclude patients with comorbid illness contraindicating trial participation; intelligence quotient < 70; or treatment with CBT, PRT, antidepressant or antipsychotic medication within the last 6 months prior to trial entry. Participants are randomised 1:1 to the experimental intervention (FCBT) versus the control intervention (FPRT) each consisting of 14 75-min sessions. All therapists deliver both interventions. Follow-up assessments occur in week 4, 8 and 16 (end-of-treatment). The primary outcome is OCD symptom severity assessed with CY-BOCS at end-of-trial. Secondary outcomes are quality-of-life and adverse events. Based on sample size estimation, a minimum of 128 participants (64 in each intervention group) are included. DISCUSSION: In our trial design we aim to reduce risk-of-bias, enhance generalisability, and broaden the outcome measures by: 1) conducting an investigator-initiated, independently funded RCT; 2) blinding investigators; 3) investigating a representative sample of OCD patients; 3) using an active control intervention (FPRT) to tease apart general and specific therapy effects; 4) using equal dosing of interventions and therapist supervision in both intervention groups; 5) having therapists perform both interventions decided by randomisation; 6) rating fidelity of both interventions; 7) assessing a broad range of benefits and harms with repeated measures. The primary study limitations are the risk of missing data and the inability to blind participants and therapists to the intervention.

The Association between Sleep Problems and Neuropsychological Deficits in Medication-naïve Children with ADHD.

BACKGROUND: Children with ADHD are reported to have sleep problems and neuropsychological deficits, but studies examining a potential association between the two are scarce and the use of varying methodology can complicate conclusions. PARTICIPANTS: A clinical sample of 59 medication-naïve children with ADHD between the ages of 6 and 14 years (71% male). METHODS: Children underwent polysomnography and multiple sleep latency test, and parent rated sleep habits on the Children's Sleep Habits Questionnaire. Children also completed an extensive neuropsychological battery of executive function and delay aversion tasks, and parents and teachers rated executive function behavior on the Behavior Rating Inventory of Executive Function. Linear regression analyses were conducted with each of the neuropsychological outcomes included as the outcome variable and the sleep parameters as the predictor variables. RESULTS: The correlations between sleep and neuropsychological outcomes were generally modest, but some sleep parameters (primarily sleep stages and sleep latencies) were associated with objectively and subjectively measured executive function and delay aversion. CONCLUSIONS: Using objective and subjective gold standard assessment procedures this study supports a (modest) association between sleep and neuropsychological function in children with ADHD.

Cost-effectiveness of a transdiagnostic psychotherapy program for youth with common mental health problems.

OBJECTIVES: Our objective was to evaluate the cost-effectiveness of the transdiagnostic psychotherapy program Mind My Mind (MMM) for youth with common mental health problems using a cost-utility analysis (CUA) framework and data from a randomized controlled trial. Furthermore, we analyzed the impact of the choice of informant for both quality-of-life reporting and preference weights on the Incremental Cost-Effectiveness Ratio (ICER). METHODS: A total of 396 school-aged (6-16 years) youth took part in the 6-month trial carried out in Denmark. CUAs were carried out for the trial period and four one-year extrapolation scenarios. Costs were based on a combination of budget and self-reported costs. Youths and parents were asked to report on the youth's quality-of-life three times during the trial using the Child Health Utility 9D (CHU9D). Parental-reported CHU9D was used in the base case together with preference weights of a youth population. Analyses using self-reported CHU9D and preference weights of an adult population were also carried out. RESULTS: The analysis of the trial period resulted in an ICER of €170,465. The analyses of the one-year scenarios resulted in ICERs between €23,653 and €50,480. The ICER increased by 24% and 71% compared to the base case when using self-reported CHU9D and adult preference weights, respectively. CONCLUSION: The MMM intervention has the potential to be cost-effective, but the ICER is dependent on the duration of the treatment effects. Results varied significantly with the choice of informant and the choice of preference weights indicating that both factors should be considered when assessing CUA involving youth.

Testing the evolutionary advantage theory of attention-deficit/hyperactivity disorder traits.

To reconcile the strong secular persistence of attention-deficit/hyperactivity disorder (ADHD) despite its impairing effects, ADHD traits have been postulated to offer an evolutionary advantage. It has been proposed that such advantages should in particular be observable under time-critical, novel, and resource-depleted conditions requiring response-readiness and high levels of scanning and exploration/foraging. Our objective was to provide the first behavioral test of this hypothesis. Schoolchildren from the general population with no/few (n = 56), mild (n = 50), moderate (n = 48), and severe (n = 48) ADHD traits, defined according to their ADHD-Rating Scale IV (ADHD-RS-IV) total score, participated in an exploratory foraging and response-readiness laboratory test. Here, children searched for coins hidden in locations of varying obscurity in an unfamiliar room for 1 min. Test-performance (number of coins found) adjusted for age, sex, and estimated IQ was analyzed categorically using multiple linear regression analyses and dimensionally by fitting a regression model including the ADHD-RS-IV score as a continuous measure. There were no differences in the mean number of coins between the No/Few (Mean = 7.82), Mild (Mean = 7.76), Moderate (Mean = 7.58), and Severe (Mean = 7.88) groups [F(3,195) = 0.24, p = 0.871]. Furthermore, excluding children with functional impairment, adjusting for verbal working memory and response inhibition, and stratifying for sex did not change these findings. Finally, continuous ADHD traits were not found to be related to test-performance [F(3,195) = 0.73, p = 0.536]. While our results do generally not support the evolutionary advantage theory (i.e., ADHD traits neither conferred an advantage nor a disadvantage), this does not disprove that ADHD traits may have offered advantages via other mechanisms.

Health anxiety symptoms in pediatric obsessive-compulsive disorder: patient characteristics and effect on treatment outcome.

The aim was to explore the potential clinical role of health anxiety (HA) symptoms in children and adolescents diagnosed with obsessive-compulsive disorder (OCD). The study investigated differences in demographic and various clinical variables between young people with OCD, with and without HA symptoms, and the effect of HA symptoms on overall OCD treatment outcome. The study sample comprised 269 children and adolescents with OCD (aged 7-17 years) from the large Nordic Long-term OCD Treatment Study. OCD symptoms and severity were assessed with The Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), which includes one item regarding HA-like obsessions and one item regarding HA-like compulsions that were used to define the HA group. Several other instruments were used to assess comorbidity and other clinical aspects. All participants were treated with 14 weekly protocolled sessions of exposure-based cognitive behavioral therapy (CBT). HA symptoms were present in 31% of participants. Other anxiety symptoms and comorbid anxiety disorders were more prevalent among those with HA symptoms. These patients also presented with significantly more types of OCD symptoms. HA symptoms were reduced following OCD treatment with CBT and having HA symptoms did not affect CBT outcome. Results suggest that pediatric OCD with HA symptoms is characterized by more anxiety symptoms and a more heterogeneous OCD symptom profile. Standardized CBT seems equally effective in treating child and adolescent OCD with or without HA symptoms.Clinical trials registration: Nordic Long-term Obsessive-Compulsive Disorder Treatment Study: www.controlled-trials.com ; ISRCTN66385119.

Systematic identification and stratification of help-seeking school-aged youth with mental health problems: a novel approach to stage-based stepped-care.

We investigated whether a novel visitation model for school-aged youth with mental health problems based on a stage-based stepped-care approach facilitated a systematic identification and stratification process without problems with equity in access. The visitation model was developed within the context of evaluating a new transdiagnostic early treatment for youth with anxiety, depressive symptoms, and/or behavioural problems. The model aimed to identify youth with mental health problems requiring an intervention, and to stratify the youth into three groups with increasing severity of problems. This was accomplished using a two-phase stratification process involving a web-based assessment and a semi-structured psychopathological interview of the youth and parents. To assess problems with inequity in access, individual-level socioeconomic data were obtained from national registers with data on both the youth participating in the visitation and the background population. Altogether, 573 youth and their parents took part in the visitation process. Seventy-five (13%) youth had mental health problems below the intervention threshold, 396 (69%) were deemed eligible for the early treatment, and 52 (9%) had symptoms of severe mental health problems. Fifty (9%) youth were excluded for other reasons. Eighty percent of the 396 youth eligible for early treatment fulfilled criteria of a mental disorder. The severity of mental health problems highlights the urgent need for a systematic approach. Potential problems in reaching youth of less resourceful parents, and older youth were identified. These findings can help ensure that actions are taken to avoid equity problems in future mental health care implementations.

Quality of life in pediatric patients with obsessive-compulsive disorder during and 3 years after stepped-care treatment.

The present study aimed to investigate the long-term quality of life (QoL) in a large sample of pediatric obsessive-compulsive disorder (OCD) patients. The study included 220 pediatric OCD patients from the Nordic Long-term OCD Treatment Study (NordLOTS) who were evaluated at seven time points before, during, and after stepped-care treatment over a 3-year follow-up period. Data from three symptom severity trajectory classes formed the basis of the QoL evaluation: acute (n = 127, N = 147), slow (n = 46, N = 63), and limited responders (n = 47, N = 59). Patients' QoL was assessed using parent and child ratings of the revised Questionnaire for Measuring Health-related Quality of Life in Children and Adolescents (KINDL-R). QoL was analyzed by trajectory class using a random mixed effects model. The association between pre-treatment factors and long-term QoL was investigated across classes in a multivariate model. Three years after treatment, the acute responder class had reached QoL levels from a general population, whereas the limited responder class had not. The slow responder class reached norm levels for the child-rated QoL only. Higher levels of co-occurring externalizing symptoms before treatment were associated with lower parent-rated QoL during follow-up, while adolescence and higher levels of co-occurring internalizing symptoms were associated with lower child-rated QoL during follow-up. For some patients, residual OCD symptoms in the years after treatment, even at levels below assumed clinical significance, are associated with compromised QoL. Co-occurring symptoms could be part of the explanation. Assessing QoL after OCD treatment, beyond the clinician-rated symptom severity, could detect patients in need of further treatment and/or assessment.

Cognitive behavioural group therapy for adolescents with ADHD: a study of satisfaction and feasibility.

BACKGROUND: Adolescents with ADHD are at increased risk of adverse outcomes and a negative life trajectory into adulthood. Evidence regarding treatment specifically tailored for the needs of this age group are still limited. High dropout rates, discontinuation of medication and treatment resistance are common issues in this population, and the patient perspective on new treatment options is therefore important. In this study, we aimed to investigate treatment satisfaction and feasibility of a group CBT program for adolescents with ADHD. We further aimed to identify any baseline characteristics predicting satisfaction. MATERIALS AND METHODS: This study was part of a larger RCT of group CBT as add-on treatment for adolescents aged 14-18 years (Mean age 15.9 years, SD 1.3) with ADHD in Norway. Satisfaction and feasibility in the treatment group (n = 48) were measured by completion of an evaluation questionnaire, attendance of group sessions and a group-leaders checklist. Predictors of satisfaction were analysed using linear regression. RESULTS: Overall satisfaction was very high with a significant age effect, the eldest participants being most satisfied. Attendance rate was high with few dropouts and medical adherence during the treatment period was good. Group-leaders generally self-evaluated adherence to treatment manual positively but addressing resistance towards homework as challenging. CONCLUSIONS: The participants were very satisfied with the group CBT treatment. Treatment options that are accepted and well-liked by the targeted population have the potential of reducing resistance towards treatment, improving future health and adherence to medication. The program is considered suitable for a clinical setting and may represent a feasible treatment supplement for adolescent ADHD.

Age differences in children with obsessive-compulsive disorder: symptoms, comorbidity, severity and impairment.

BACKGROUND: Studies on child and adolescent obsessive-compulsive disorder (OCD) indicate that symptom severity is similar across age, but significant age differences of symptom profile and comorbid disorders have been observed. These earlier studies have yielded mixed results, are methodologically heterogenous and tend to have fairly small sample sizes. The current study examines these differences in one of the largest samples to date and the first sample outside of an English-speaking cultural context. METHODS: We compared children aged 11 years and younger to adolescents aged 12 years and older from the Nordic Long-Term Obsessive-Compulsive Disorder Treatment Study that included 269 children and adolescents with a primary diagnosis of OCD. The two groups were compared on measures of OCD severity, symptom profile, comorbid symptoms, and functional impairment. RESULTS: Results showed that the younger group had a poorer level of insight, higher rates of ADHD, and disruptive disorders. The older group had higher levels of mental compulsions, miscellaneous obsessions and compulsions, and self-rated functional impairment. No differences were found on the prevalence of anxiety, tic or depressive disorders between the age groups, nor on overall OCD severity. CONCLUSION: Overall, differences between the age groups were found to be less than in previous research. Defining groups by age of onset and duration of illness rather than age at evaluation did not change results. Mental health services in Scandinavia are free of cost, making early intervention more accessible, which may reduce subsequent secondary problems and explain these findings.
