Patterns of sub-optimal change following CBT for childhood anxiety.

BACKGROUND: Children and adolescents demonstrate diverse patterns of symptom change and disorder remission following cognitive behavioural therapy (CBT) for anxiety disorders. To better understand children who respond sub-optimally to CBT, this study investigated youths (N = 1,483) who continued to meet criteria for one or more clinical anxiety diagnosis immediately following treatment or at any point during the 12 months following treatment. METHODS: Data were collected from 10 clinical sites with assessments at pre-and post-treatment and at least once more at 3, 6 or 12-month follow-up. Participants were assigned to one of three groups based on diagnostic status for youths who: (a) retained an anxiety diagnosis from post to end point (minimal responders); (b) remitted anxiety diagnoses at post but relapsed by end point (relapsed responders); and (c) retained a diagnosis at post but remitted to be diagnosis free at end point (delayed responders). Growth curve models assessed patterns of change over time for the three groups and examined predictors associated with these patterns including demographic, clinical and parental factors, as well as treatment factors. RESULTS: Higher primary disorder severity, being older, having a greater number of anxiety disorders, having social anxiety disorder, as well as higher maternal psychopathology differentiated the minimal responders from the delayed and relapsed responders at the baseline. Results from the growth curve models showed that severity of the primary disorder and treatment modality differentiated patterns of linear change only. Higher severity was associated with significantly less improvement over time for the minimal and relapsed response groups, as was receiving group CBT, when compared to the delayed response group. CONCLUSIONS: Sub-optimal response patterns can be partially differentiated using variables assessed at pre-treatment. Increased understanding of different patterns of change following treatment may provide direction for clinical decision-making and for tailoring treatments to specific groups of clinically anxious youth. Future research may benefit from assessing progress during treatment to detect emerging response patterns earlier.

Long-Term Effectiveness of Cognitive Behavioral Therapy in Routine Outpatient Care for Youth with Anxiety Disorders.

INTRODUCTION: This study examined the long-term effectiveness of cognitive behavioral therapy (CBT) (≥ 2 years after the end of therapy) in the routine care of youth (mean 11.95 years; SD = 3.04 years) with primary anxiety disorder (AD). METHODS: Two hundred and ten children with any AD as a primary diagnosis and with any comorbidity were included in the "Kids Beating Anxiety (KibA)" clinical trial and received evidence-based CBT. Diagnoses, severity of diagnoses, and further dimensional outcome variables of symptoms and functioning were assessed before (baseline), after the last treatment session (POST), and at two follow-up (FU) assessments in the child and caregiver report: 6 months (6MONTHS-FU) and >2 years (mean 4.31; SD = 1.07 years) after the last treatment session (long-term FU). RESULTS: At POST, 61.38% showed total remission of all and any ADs. At long-term FU, the remission rate was 63.64%. Compared to baseline, ratings of severity, anxiety, impairment/burden, and life quality improved significantly after CBT in child and caregiver report. All pre-post/FU improvements and global success ratings were stable in child (Pre-Post: Hedges' g = 3.57; Pre-6MONTHS-FU: Hedges' g = 3.43; Pre-LT-FU: Hedges' g = 2.34) and caregiver report (Pre-Post: Hedges' g = 2.00; Pre-6MONTHS-FU: Hedges' g = 2.31; Pre-LT-FU: Hedges' g = 2.31) across all POST- and FU-assessment points. Some outcomes showed further significant improvement, and no deterioration was found over the course of time. Effect sizes calculated in the present study correspond to, or even exceed, effect sizes reported in previous meta-analysis. CONCLUSIONS: Stable long-term effects of "KibA" CBT for youth with ADs, comparable to those results from efficacy studies, were achieved in a routine practice setting by applying treatment manuals tested in randomized controlled trials. These findings are remarkable, as the patient group studied here consisted of an age group within the main risk phase of developing further mental disorders, and therefore an increase in new-onset anxiety and further mental disorders would be expected over the long time span studied here.

[Bullying experiences in outpatients of a child and adolescent psychotherapy centre - A particularly vulnerable group?] / Bullying-Erfahrungen bei PatientInnen einer Ambulanz für Kinder- und Jugendpsychotherapie ­ eine besonders gefährdete Gruppe?

Bullying experiences in outpatients of a child and adolescent psychotherapy centre - A particularly vulnerable group? Abstract. Objective: Bullying has both short- and long-term effects on physical and mental health. Thus, more victimized children might tend to be found in clinical samples. This is the first study to examine the prevalence of bullying roles and modes in children/adolescents in a psychotherapeutic outpatient setting in Germany. Method: 298 outpatients being treated in a child/adolescent psychotherapy centre (6-20 years, 50.7 % female) completed a questionnaire concerning their bullying experiences over the last 6 months. Results: 24.5 % of the patients reported from a victim's perspective, independent of being perpetrators of bullying. 19.1 % reported solely as victims, 5.4 % as victims who also bullied (bully-victims), and 2.0 % as bullies. More than one-third of those with victim or bully-victim experiences had been polyvictimized, 86.2 % were victims solely of traditional bullying, and 1.4 % solely of cyberbullying. The exploratory comparison to general-population school samples seems to show significantly more patients with victim experiences and significantly less patients who bullied others. There seem to be no significant effects for bully-victims. Compared to an inpatient sample, significantly fewer adolescent patients seem to state being victims or bully-victims. Conclusions: Bullying is a topic of particular importance in the context of psychotherapy. These findings have implications for the psychotherapeutic practice as well as training settings.

Non-replication of the association between 5HTTLPR and response to psychological therapy for child anxiety disorders.

BACKGROUND: We previously reported an association between 5HTTLPR genotype and outcome following cognitive-behavioural therapy (CBT) in child anxiety (Cohort 1). Children homozygous for the low-expression short-allele showed more positive outcomes. Other similar studies have produced mixed results, with most reporting no association between genotype and CBT outcome. AIMS: To replicate the association between 5HTTLPR and CBT outcome in child anxiety from the Genes for Treatment study (GxT Cohort 2, n = 829). METHOD: Logistic and linear mixed effects models were used to examine the relationship between 5HTTLPR and CBT outcomes. Mega-analyses using both cohorts were performed. RESULTS: There was no significant effect of 5HTTLPR on CBT outcomes in Cohort 2. Mega-analyses identified a significant association between 5HTTLPR and remission from all anxiety disorders at follow-up (odds ratio 0.45, P = 0.014), but not primary anxiety disorder outcomes. CONCLUSIONS: The association between 5HTTLPR genotype and CBT outcome did not replicate. Short-allele homozygotes showed more positive treatment outcomes, but with small, non-significant effects. Future studies would benefit from utilising whole genome approaches and large, homogenous samples.

HPA AXIS RELATED GENES AND RESPONSE TO PSYCHOLOGICAL THERAPIES: GENETICS AND EPIGENETICS.

BACKGROUND: Hypothalamic-pituitary-adrenal (HPA) axis functioning has been implicated in the development of stress-related psychiatric diagnoses and response to adverse life experiences. This study aimed to investigate the association between genetic and epigenetics in HPA axis and response to cognitive behavior therapy (CBT). METHODS: Children with anxiety disorders were recruited into the Genes for Treatment project (GxT, N = 1,152). Polymorphisms of FKBP5 and GR were analyzed for association with response to CBT. Percentage DNA methylation at the FKBP5 and GR promoter regions was measured before and after CBT in a subset (n = 98). Linear mixed effect models were used to investigate the relationship between genotype, DNA methylation, and change in primary anxiety disorder severity (treatment response). RESULTS: Treatment response was not associated with FKBP5 and GR polymorphisms, or pretreatment percentage DNA methylation. However, change in FKBP5 DNA methylation was nominally significantly associated with treatment response. Participants who demonstrated the greatest reduction in severity decreased in percentage DNA methylation during treatment, whereas those with little/no reduction in severity increased in percentage DNA methylation. This effect was driven by those with one or more FKBP5 risk alleles, with no association seen in those with no FKBP5 risk alleles. No significant association was found between GR methylation and response. CONCLUSIONS: Allele-specific change in FKBP5 methylation was associated with treatment response. This is the largest study to date investigating the role of HPA axis related genes in response to a psychological therapy. Furthermore, this is the first study to demonstrate that DNA methylation changes may be associated with response to psychological therapies in a genotype-dependent manner.
