Evaluation of cognitive behaviour therapy for paediatric obsessive-compulsive disorder in the context of tic disorders

Measuring psychological outcomes in paediatric settings: Making outcomes meaningful using client-defined perspectives

There is a growing drive to develop and implement patient-reported outcome measures within paediatric health services, particularly for young people living with chronic health conditions; however, there is little consensus on how best to do this in meaningful ways within psychological services working alongside medical teams. This reflective commentary considers some of the challenges of collecting psychological outcome measures in paediatric services and considers alternative approaches to making outcome measurement meaningful. All measures have their limitations; however, they become meaningless if they are not used in meaningful and considered ways with young people. Client-defined outcome measurement, such as goal-based outcome measures, alongside other types of measurement, can capture outcomes of meaning to young people living with chronic health conditions, and can enable them to feed into a shared decision-making process.

Psychopharmacotherapy of Obsessive-Compulsive Symptoms within the Framework of Tourette Syndrome

While Behavioral Therapy (BT) should be recommended as the first step in the treatment of OCD as well as TS, medication can be added for augmentation and in certain situations (e.g. family preference, BT not available or feasible) the priority may even reverse. This narrative review is given on the complexity of drug treatment in patients comorbid with obsessive-compulsive disorder (OCD) and Tourette syndrome (TS) and other tic problems. OCD with TS is a co-occurring combination of the two generally delimitable, but in detail, also overlapping disorders which wax and wane with time but have different courses as well as necessities and options of treatment. Distinct subtypes like “tic-related OCD” are questionable. Obsessive-compulsive symptoms (OCS) and tics are frequently associated (OCS in TS up to 90%, tics in OCD up to 37%). Sensory-motor phenomena like urges and just-right feelings reflect some behavioral overlap. The main additional psychopathologies are attention-deficit hyperactivity disorder (ADHD), mood problems and anxiety. Also, hair pulling disorder and skin picking disorder are related to OCD with TS. Hence, the assessment and drug treatment of its many psychopathological problems need high clinical experience, careful planning, and ongoing evaluation/adaptation. Drugs are able to reduce clinical symptoms but cannot cure the disorders, which should be treated in parallel in their own right; i.e. for OCD serotonin reuptake inhibitors (SSRI) and for TS (tics), certain antipsychotics can be successfully prescribed. In cases of OCD with tics, when OCS responds only partially, an augmentation with antipsychotics (recommended: risperidone and aripiprazole) may improve OCS as well as tics. Also, the benzamide sulpiride, an atypical antipsychotics, may be beneficial in treating the combination of OCS, tics and anxious-depressive problems.

Probably, any additional psychopathologies of OCD might attenuate the effectiveness of SSRI on OCS; on the other hand, in cases of OCD with tics, SSRI may reduce not only OCS but also stress sensitivity and emotional problems and thus leading to better selfregulatory abilities, useful to improve tic suppression.

In sum, some clinical guidance can be given, but there remain many uncertainties because of a scarce database for psychopharmacotherapy in OCD with TS.

Systematic review of co-occurring OCD and TD: Evidence for a tic-related OCD subtype?

OBJECTIVE

The aim of this review is to summarize the current knowledge of associated features of co-occurring obsessive-compulsive disorder (OCD) and tic disorders (TD) and to critically evaluate hypotheses regarding the nature of their comorbidity.

METHOD

We conducted a systematic review following PRISMA guidelines. To this aim, the PubMed, PsychInfo and ISI Web of Knowledge databases were searched up to August 30, 2018. For gender and age-of-onset we additionally conducted meta-analyses.

RESULTS

One hundred eighty-nine studies met inclusion criteria. We substantiate some acknowledged features and report evidence for differential biological mechanisms and treatment response. In general, studies were of limited methodological quality.

CONCLUSIONS

Several specific features are reliable associated with co-occurring OCD + TD. The field lacks methodological sound studies. The review found evidence against and in favor for different hypotheses regarding the nature of comorbidity of OCD and TD. This could indicate the existence of a stepwise model of co-morbidity, or could be an artefact of the low methodological quality of studies.

Moderators and predictors of response to cognitive behaviour therapy for pediatric obsessive-compulsive disorder: A systematic review

We report a systematic review of moderators of CBT efficacy for pediatric OCD relative to other treatments. CENTRAL, MEDLINE, EMBASE, CINAHL, and PsycINFO were searched for RCTs reporting on effect moderation for CBT outcomes. Five studies (N = 365) examined 17 variables with three significant moderators identified. Compared to pill-placebo, CBT monotherapy was not effective for children with a family history of OCD but was for those without a family history. For children with a family history, CBT plus sertraline efficacy was attenuated but remained significant. For children with tics, CBT but not sertraline remained superior to pill-placebo. For non-responders to initial treatment with CBT, continuing CBT was inferior to commencing sertraline for those with tics but was not different for those without tics. A supplementary review identified older age, symptom and impairment severity, co-morbidity and family accommodation as consistent predictors of a poorer outcome to CBT. Current evidence for moderation effects is post-hoc, from single RCTs, has small Ns and requires replication. The review identifies family history of OCD and the presence of tics as factors requiring further examination in properly conducted trials and about which clinicians need to show care in their treatment recommendations.

Pediatric obsessive-compulsive disorder with tic symptoms: clinical presentation and treatment outcome

Some studies have shown that children and adolescents with obsessive-compulsive disorder (OCD) and co-morbid tics differ from those without co-morbid tics in terms of several demographic and clinical characteristics. However, not all studies have confirmed these differences. This study examined children and adolescents with OCD and with possible or definite tic specifiers according to the DSM-5 in order to see whether they differ from patients without any tic symptoms regarding clinical presentation and outcome of cognitive behavioral therapy (CBT). The full sample included 269 patients (aged 7-17) with primary DSM-IV OCD who had participated in the Nordic Long-term Treatment Study (NordLOTS). Symptoms of tics were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). One or more tic symptoms were found in 29.9% of participants. Those with OCD and co-morbid tic symptoms were more likely male, more likely to have onset of OCD at an earlier age, and differed in terms of OCD symptom presentation. More specifically, such participants also showed more symptoms of OCD-related impairment, externalization, autism spectrum disorder (ASD), social anxiety, and attention-deficit/hyperactivity disorder (ADHD). However, the two groups showed no difference in terms of OCD severity or outcome of CBT. Children and adolescents with OCD and co-morbid tic symptoms differ from those without tic symptoms in several aspects of clinical presentation, but not in their response to CBT. Our results underscore the effectiveness of CBT for tic-related OCD.

Innovation in obsessive compulsive disorder: A commentary

As noted in this commentary, the research in this special issue presents several conceptual and methodological innovations that advance out understanding of obsessions and compulsions. The issue spans a broad range of topics from basic psychological processes such as selfhood themes, perceptions of internal states, and preference for visual symmetry to new insights into compulsions and other forms of neutralization to promising treatment approaches for special OCD symptom presentations. The implications of this research for understanding vulnerability to OCD and the role of compulsions are discussed and three methodological challenges are highlighted that require further attention by OCD researchers.
