Secondary outcomes from the pediatric obsessive compulsive disorder treatment study II

Secondary outcomes of enhanced cognitive behavioral therapy (eCBT) for children and adolescents with obsessive-compulsive disorder

Background

Obsessive-compulsive disorder (OCD) is a debilitating mental health condition usually presenting with a high degree of comorbid symptoms in the majority of cases. Although face-to-face cognitive-behavioral therapy (CBT) is considered the therapeutic golden standard for pediatric OCD, its accessibility, availability, and consistency in delivery are still limited. To address some of these challenges, an enhanced CBT (eCBT) package was created and introduced. This study explored eCBT's broad-based impact on OCD-related comorbid symptoms, functional impairment, quality of life and family accommodation among youth with OCD.

Methods

This open trial involved 25 pediatric patients with OCD (7-17 years), assessed between January 2018 to February 2020. All patients received eCBT for 14 weeks. Secondary outcomes were assessed at baseline, post-treatment, and 3-, 6-, and 12-month follow-up co-occurring symptoms were evaluated using the Strengths and Difficulties Questionnaire (SDQ), Screen for Child Anxiety-Related Emotional Disorders (SCARED), and Mood and Feelings Questionnaire (MFQ). Quality of life was measured using the KINDL-R, functional impairment through the Child Obsessive-Compulsive Impact Scale Revised (COIS-R), and family accommodation by the Family Accommodation Scale (FAS). Linear mixed-effects models were applied to analyze treatment effects.

Results

Results indicated a significant decrease in OCD-related comorbid symptoms post-treatment, with SDQ mean reduce of 3.73 (SE = 1.10, child) and 4.14 (SE = 1.19, parent), SCARED mean reduce of 10.45 (SE = 2.52, child) and 8.40 (SE = 2.82, parent), MFQ mean reduce of 3.23 (SE = 1.11, child) and 2.69 (SE = 1.18, parent). Family accommodation declined with clinician scored FAS mean reduction of 13.25 (SE = 2.31). Quality-of-Life improved significantly post-treatment, with KINDL mean increase of 8.15 (SE = 2.87, children), and 10.54 (SE = 3.07, parents). These positive improvements were further amplified at the 3-month follow-up and remained consistent at the 12-month follow-up.

Conclusion

A significant reduction was observed in all secondary outcomes employed and OCD-related functional impairments from baseline to post-treatment, which was maintained through 12-month follow-up. These results imply that after receiving eCBT, children and adolescents experienced substantial decrease in the negative impacts of OCD-related symptoms on their daily life, including home, school, and social interactions.

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.

Effects of Treatment Setting on Outcomes of Flexibly-Dosed Intensive Cognitive Behavioral Therapy for Pediatric OCD: A Randomized Controlled Pilot Trial

Introduction: Optimizing individual outcomes of cognitive-behavioral therapy (CBT) remains a priority. Methods: Youth were randomized to receive intensive CBT at a hospital clinic (n = 14) or within their home (n = 12). Youth completed 3 × 3 h sessions (Phase I) and up to four additional 3-h sessions as desired/needed (Phase II). An independent evaluator assessed youth after Phase I, Phase II (when applicable), and at 1- and 6-months post-treatment. A range of OCD-related (e.g., severity, impairment) and secondary (e.g., quality of life, comorbid symptoms) outcomes were assessed. Results: Families' satisfaction with the treatment program was high. Of study completers (n = 22), five youth (23%) utilized no Phase II sessions and 9 (41%) utilized all four (Median Phase II sessions: 2.5). Large improvements in OCD-related outcomes and small-to-moderate benefits across secondary domains were observed. Statistically-significant differences in primary outcomes were not observed between settings; however, minor benefits for home-based treatment were observed (e.g., maintenance of gains, youth comfort with treatment). Discussion: Intensive CBT is an efficacious treatment for pediatric OCD. Families opted for differing doses based on their needs. Home-based treatment, while not substantially superior to hospital care, may offer some value, particularly when desired/relevant.

Obsessive-compulsive symptoms and their links to depression and anxiety in clinic- and community-based pediatric samples: A network analysis

BACKGROUND

Symptoms of depression and anxiety are common in children with obsessive-compulsive disorder (OCD) and associated with more severe OCD, greater impairment, and worse treatment outcome. Beyond twin studies showing that genetic factors contribute to the high co-occurrence, few studies have examined how OCD, depression, and anxiety are linked in youth, and current studies often fail to account for OCD and anxiety heterogeneity.

METHODS

Network analysis was used to investigate how OCD were linked to depression and anxiety in multinational youth diagnosed with OCD (total n = 419) and in school-recruited, community-based samples of youth (total n = 2 991).

RESULTS

Initial results aligned with earlier work showing that severity of obsession-related symptoms are important in linking OCD to depression in youth with OCD. However, when symptom content of OCD (e.g., washing, ordering) was fully taken into account and when measures of anxiety were included, specific OCD symptom dimensions (primarily obsessing and doubting/checking) were linked to specific anxiety dimensions (primarily panic and generalized anxiety) which in turn were linked to depression. These results were replicated in three separate community-based samples from Chile, Italy, and Spain using different measures of anxiety and depression.

LIMITATIONS

Cross-sectional data were analyzed which precludes causal inference. Self-report measures were used.

CONCLUSIONS

Youth with OCD with symptoms related to doubting/checking and obsessing should be carefully assessed for symptoms of panic and generalized anxiety. Non-responders to standard OCD treatment may benefit from interventions targeting panic and generalized anxiety, but more research is needed to test this hypothesis.

Assessing Acute Secondary Treatment Outcomes in Early-Onset Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) in children under 8 years of age, referred to as early-onset OCD, has similar features to OCD in older children, including moderate to severe symptoms, impairment, and significant comorbidity. Family-based cognitive behavioral therapy (FB-CBT) has been found efficacious in reducing OCD symptoms and functional impairment in children ages 5-8 years with OCD; however, its effectiveness on reducing comorbid psychiatric symptoms in this same population has yet to be demonstrated. This study examined the acute effects of FB-CBT vs. family-based relaxation treatment over 14 weeks on measures of secondary treatment outcomes (non-OCD) in children with early-onset OCD. Children in the FB-CBT condition showed significant improvements from pre- to post-treatment on secondary outcomes, with a decrease in overall behavioral and emotional problems, internalizing symptoms, as well as overall anxiety symptom severity. Neither condition yielded significant change in externalizing symptoms. Clinical implications of these findings are considered.

Coercive and disruptive behaviors mediate group cognitive-behavioral therapy response in pediatric obsessive-compulsive disorder

PURPOSE

Coercive and disruptive behaviors (CDBs) are commonplace in pediatric obsessive-compulsive disorder (OCD) and are associated with increased disorder impact and reduced treatment response. Prior research suggests that CDBs mediate the cross-sectional relationship between family accommodation and OCD symptom severity; however, the impact of reducing CDBs on other treatment outcomes has yet to be studied.

METHODS

Participants comprised 49 OCD-affected youth (42.9% male, M_age at baseline = 13.7) and their parent(s) who completed a 12-week, group family-based cognitive-behavioral treatment at an OCD specialty clinic. Outcomes included parent-report measures of CDBs, family accommodation, symptom severity, and both child- and family-level impairment. Descriptive, correlation, and regression analyses were followed by tests of indirect effects (mediation).

RESULTS

Changes in all outcome variables had moderate to strong correlations with each other. As hypothesized, CDB decreases predicted positive changes in OCD severity as well as in child and family impairment. Further, whereas improvement in OCD severity predicted changes in child and family impairment, improvements in family accommodation were not directly predictive of any outcomes. Consistent with hypotheses, changes in CDBs mediated relationships between changes in accommodation and child- and family-level impairment, as well as relationships between changes in OCD severity and both levels of impairment. Additional exploratory analyses found that changes in symptom severity significantly mediated relationships between changes in CDBs and both levels of impairments.

CONCLUSIONS

Findings suggest that attention to reducing CDBs is warranted in the treatment of pediatric OCD, and that accommodation reductions lead to meaningful improvements in child and family functioning only when CDBs and/or symptoms are also reduced. Future family-based treatments may benefit from inclusion of components specifically targeting CDBs that occur within the context of accommodating OCD symptoms.

Psychiatric Treatment and Management of Psychiatric Comorbidities of Movement Disorders

Pediatric movement disorders may present with psychiatric symptoms at many points during the course of the disease. For the relatively common pediatric movement disorder, Tourette syndrome, psychiatric comorbidities are well-described and treatment is well-studied. Managing these comorbidities may be more effective than improving the movements themselves. For more uncommon movement disorders, such as juvenile-onset Huntington disease, treatment of psychiatric comorbidities is not well-characterized, and best-practice recommendations are not available. For the least common movement disorders, such as childhood neurodegeneration with brain iron accumulation, psychiatric features may be nonspecific so that underlying diagnosis may be apparent only after recognition of other symptoms. However, psychiatric medication, psychotherapy, and psychosocial support for these disorders may prove helpful to many children and adolescents.
