- A recent study identified three distinct treatment-response trajectories in pediatric OCD where higher levels of contamination symptoms predicted a limited response to cognitive-behavioral therapy (CBT). This study extends these findings by examining which specific symptoms characterize limited CBT response from baseline to 3-year follow-up, with an emphasis on contamination symptoms. The study sample comprised 269 pediatric patients with OCD, all receiving stepped-care treatment with manualized CBT. Differences in single item-reporting between the three trajectory groups were examined using linear mixed-effect modeling. Limited responders displayed a higher symptom load across all OCD symptom categories at 3-year follow-up, dominated by contamination symptoms. Five of these (obsessions about dirt and germs, about bodily fluids, about the feeling of contamination and compulsions regarding handwashing and showering) showed persistence from baseline to 3-year follow-up. The results indicate that presence of specific contamination symptoms may influence long-term symptom severity trajectories in young patients with OCD.

- Background First-line treatments for pediatric obsessive-compulsive disorder (OCD) include exposure-based cognitive-behavioral therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs). No studies have thus far identified distinct classes and associated predictors of long-term symptom severity during and after treatment. Yet, these could form the basis for more personalized treatment in pediatric OCD. Method The study included 269 OCD patients aged 7-17 years from the Nordic Long-term OCD Treatment Study (NordLOTS). All participants received stepped-care treatment starting with 14 weekly sessions of manualized CBT. Nonresponders were randomized to either prolonged CBT or SSRIs. Symptom severity was assessed using the Children's Yale-Brown Obsessive-Compulsive Scale at seven time points from pre- to post-treatment and over a three-year follow-up. Latent class growth analysis (LCGA) was performed to identify latent classes of symptom severity trajectories. Univariate and multivariate analyses were used to detect differences between classes and identify predictors of trajectory class membership including several clinical and demographic variables. Trial registry: Nordic Long-term Obsessive-Compulsive Disorder (OCD) Treatment Study; ; ISRCTN66385119. Results Three LCGA classes were identified: (a) acute, sustained responders (54.6%); (b) slow, continued responders (23.4%); and (c) limited long-term responders (21.9%). Class membership was predicted by distinct baseline characteristics pertaining to age, gender, symptom presentation, insight, avoidance, and comorbidity. Conclusions The LCGA suggests three distinct trajectory classes of long-term symptom severity during and after treatment in pediatric OCD with different clinical profiles at pretreatment. The results point to required clinical attention for adolescent patients with contamination/cleaning symptoms and reduced insight who do not show convincing responses to first-line treatment even though they may have reached the established cutoff for treatment response.

Quality of life in pediatric patients with obsessive-compulsive disorder during and 3 years after stepped-care treatment
- 2022

In: European Child & Adolescent Psychiatry. - : Springer Science and Business Media LLC. - 1018-8827 .- 1435-165X. ; 31:9, s. 1377-1389

Journal article (peer-reviewed)abstract
- 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.

Body Dysmorphic Symptoms in Youth with Obsessive-compulsive Disorder: Prevalence, Clinical Correlates, and Cognitive Behavioral Therapy Outcome
- 2022
-
In: Child Psychiatry & Human Development. - : Springer Science and Business Media LLC. - 0009-398X .- 1573-3327. ; 54:4, s. 939-48
-
Journal article (peer-reviewed)abstract
- 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.

Journal article (peer-reviewed)abstract
- Objective: Insight and avoidance are commonly discussed factors in obsessive-compulsive disorder (OCD) that have demonstrated associations with increased severity as well as reduced treatment response in adults, but these factors have not been sufficiently examined in pediatric OCD. This study examined the impacts of avoidance, insight, and impairment recognition concordance on cognitive-behavioral therapy (CBT) outcomes as well as impacts of CBT on insight and avoidance in a large sample of youths affected by OCD. Method: Data from 573 OCD-affected youths enrolled in CBT trials were aggregated. Children's Yale-Brown Obsessive-Compulsive Scale items measured treatment response, insight, and avoidance. Standardized differences between child and parent ratings of impairment were used to calculate impairment recognition concordance. Binary logistic regression was used to identify variables associated with treatment response. Results: Greater avoidance, limited child recognition of impairment, older age, and lower baseline severity predicted reduced likelihood of treatment response, but insight did not. Both insight and avoidance improved significantly following CBT. Response rates were lower when posttreatment insight and avoidance were worse. Conclusion: Contrasting with prevailing belief, poor insight does not appear to limit CBT response potential in pediatric OCD. Avoidance and impairment recognition are understudied CBT response predictors and warrant further consideration in pediatric OCD. Clinicians should attend to these factors to optimize outcomes for children affected by this common, debilitating illness.

Family Accommodation in Pediatric Obsessive-Compulsive Disorder: Investigating Prevalence and Clinical Correlates in the NordLOTS Study
- 2023

-
Journal article (peer-reviewed)abstract
- Family accommodation (FA) involves the actions taken by family members, particularly parents, to accommodate a child & PRIME;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.
