This study evaluated the long-term durability of individual and group cognitive-behavioral family-based therapy (CBFT) for childhood obsessive-compulsive disorder (OCD). Thirty-eight participants (age 13-24 years) from a randomized controlled trial of individual or group CBFT for childhood OCD were assessed 7 years post-treatment. Diagnostic, symptom severity interviews and self-report measures of OCD, anxiety, and depression were administered. Seven years after treatment, 79% of participants from individual therapy and 95% from group therapy had no diagnosis of OCD. These results are near identical to results found at 12 and 18 months follow-ups of the same sample. No significant differences were found between treatment conditions, self-reports of symptom severity, except that depressive symptoms were significantly more pronounced for individual treatment condition, and those in the older age group (19-24 years of age). Results suggest that CBFT for obsessive-compulsive disorder is effective 7 years post-treatment.

BackgroundStudies have shown that unaccompanied refugee children have elevated symptoms of post-traumatic stress disorder (PTSD), depression, anxiety, and externalizing problems. Few studies have examined change in this group’s mental health symptoms after resettlement in a new country, particularly for those who arrive to a host country when being under the age of 15.MethodThe sample included 75 unaccompanied refugee children (mean age 16.5 years, SD =1.6; 83% boys) who settled in Norway. We examined change in the number of stressful life events, symptoms of PTSD (Child PTSD Symptom Scale; CPSS), and symptoms of anxiety, depression and externalizing problems (Hopkins Symptom Checklist; HSCL-37A) from 6 months after arrival (T1) to 1.9 years (SD =0.6) later (T2) using paired samples t-tests. Linear regression models were used to examine whether length of stay, level of education or change in the number of experienced stressful life events predicted symptom change.ResultsThere was a small and non-significant change in the mean scores of both symptom scales between T1 and T2, although there was considerable variation among the participants. The number of children who remained above the clinical cut-off value from T1 to T2 was as follows: 28 of 47 (59.6%) on the CPSS and eight of 16 (50.0%) on the HSCL-37A. There was a significant increase in the number of reported stressful life events from T1 to T2. An increase in reported stressful life events predicted an increase in PTSS (β =1.481, 95% CI .552 to 2.411). Length of stay, increase in stressful life events and level of education did not predict changes in the HSCL-37A.ConclusionsThere was no average change in the level of PTSS, depression, anxiety, or externalizing problems in this group of unaccompanied refugee children from shortly after arrival to nearly two years later. The large variation in change scores across informants indicates a need for monitoring the development of mental health problems and securing that the youth’s primary psychosocial needs are met. The high rate of children above clinical cut-off on the symptoms scales and with suicidal ideation indicates that many may be in need of treatment.

OBJECTIVE Conducted a randomized controlled trial to investigate the effectiveness of cognitive behavioral therapy (CBT), and compared the relative effectiveness of individual (ICBT) and group (GCBT) treatment approaches for anxiety disorders in children and adolescents. METHODS Referred youth (N = 182, M age = 11.5 years, range 8-15 years, 53% girls) with separation anxiety, social phobia, or generalized anxiety disorder were randomly assigned to ICBT, GCBT or a waitlist control (WLC) in community clinics. Pre-, post-, and one year follow-up assessments included youth and parent completed diagnostic interview and symptom measures. After comparing CBT (ICBT and GCBT combined) to WLC, ICBT and GCBT were compared along diagnostic recovery rates, clinically significant improvement, and symptom measures scores using traditional hypothesis tests, as well as statistical equivalence tests. RESULTS Significantly more youth lost all anxiety disorders after CBT compared to WLC. Full diagnostic recovery rate was 25.3% for ICBT and 20.5% in GCBT, which was not significantly different. There was continued lack of significant differences between ICBT and GCBT at one year follow-up. However, equivalence between GCBT and ICBT could only be demonstrated for clinical severity rating of the principal anxiety disorder and child reported anxiety symptoms post-treatment. CONCLUSION Findings support the effectiveness of CBT compared to no intervention for youth with anxiety disorders, with no significant differences between ICBT and GCBT. However, the relatively low recovery rates highlight the need for further improvement of CBT programs and their transportability from university to community settings.

The aim of this study was to examine the factor structure and psychometric properties of an observer-rated youth alliance measure, the Therapy Process Observational Coding System for Child Psychotherapy–Alliance scale (TPOCS–A). The sample was 52 youth diagnosed with anxiety disorders (M age = 12.43, SD = 2.23, range = 8–15; 56% boys; 98% Caucasian) drawn from a randomized controlled trial. Participants received a manualized individual cognitive behavioral treatment, the FRIENDS for life program, in public community clinics in Norway. Diagnostic status, treatment motivation, and perceived treatment credibility were assessed at pretreatment. Using the TPOCS–A, independent observers rated child–therapist alliance from the third therapy session. Child- and therapist-reported alliance measures were collected from the same session. An exploratory factor analysis supported a one-factor solution, which is consistent with previous studies of self- and observer-rated youth alliance scales. Psychometric analyses supported the interrater reliability, internal consistency, and convergent/divergent validity of the TPOCS–A. Accumulating psychometric evidence indicate that the TPOCS–A has the potential to fill a measurement gap in the youth psychotherapy field. In youth psychotherapy, alliance may be unidimensional, so establishing a strong bond and engaging the child in therapeutic activities may both be instrumental to establishing good alliance early in treatment. However, it is important to be cautious when interpreting the factor analytic findings, because the sample size may have been too small to identify additional factors. Future research can build upon these findings by examining the factor structure of youth alliance measures with larger, more diverse samples.

Unaccompanied asylum-seeking children aged 10–16 years (N = 93, M = 13.8, SD = 1.4, 81% boys) were assessed 6 months after arrival in Norway (SD = 5 months). Participants originated from 14 countries (63% Asia; 36% Africa). Severe life events (SLE) and psychological symptoms were measured by self-report. Participants reported a mean of 5.5 SLE (SD = 2.4), the most prevalent being death of a close person (68%), witnessing violence (63%), and war (62%). Some 54% scored above clinical cutoff on posttraumatic stress symptoms, 30% on anxiety symptoms, 20% on depressive symptoms, and 7% on externalizing symptoms. Number of SLE was associated with posttraumatic stress disorder symptoms (r =.50, p < .001), depression (r =.27, p = .020), and anxiety symptoms(r =. 34, p = .003), but not externalizing symptoms (r =.02, p = .874). None of the symptom variables were associated with age or gender. Results indicate that many unaccompanied asylum-seeking children have experienced not only war-related traumas but several other severe life adversities as well. It may thus be helpful to conduct early assessments on this group of children to assess their need for treatment or other psychosocial interventions.

“It can save you if you just forget”: Closeness and Competence as Conditions for Coping among Ugandan Orphans

Krister W. Fjermestad; Ingrid Kvestad; Marguerite Daniel; Gro Th. Lie

This article explores the coping strategies of orphaned children and their caregivers supported by a community-based organization in a Ugandan slum area. In-depth qualitative interviews were conducted with eight orphans (aged 12 to 16 years) and their caregivers selected by the community-based organization. The children had experienced several co-occurring risk factors such as loss and separation, poverty, disease, and an unsafe environment. Most caregivers were extended family members. One caregiver was an unrelated foster carer. Three of the households were child-headed. Data were analysed using an adapted approach of Giorgios (Hafting, 1995; Malterud, 2001) psychological-phenomenological method. Participating children from child-headed households lacked protective factors associated with closeness (i.e., supportive dyadic relationships). All the children in the study experienced competence in the arenas of school and household chores. Cultural advice on handling adversity, including ‘forgetting’, ‘accepting’ and ‘adjusting’, appears to contradict Western theories of coping. Sommerschilds theoretical model on the conditions for coping was effective in identifying conditions in childrens lives that may impair their coping, self-worth, and resilience.

Relationship Factors and Outcome in Child Anxiety Treatment Studies

Krister W. Fjermestad; Bente Storm Mowatt Haugland; Einar Heiervang; Lars-Göran Öst

This study reviews 19 randomized controlled trials examining the association between three relationship factors — participation, treatment involvement, and therapeutic relationship — and outcome of cognitive-behavioral anxiety treatments for children and adolescents. In 12 studies, parent participation was considered as an independent variable compared to child-only participation. In three studies, parental involvement was measured. Child involvement was measured in one study. The childs perception of the therapeutic relationship was considered in three studies. Six studies found a significant positive effect of parent participation on diagnostic status, symptom level, or global functioning outcome measures. One study found a significant effect of parental involvement on global outcome measures. Another study found a significant positive association between child involvement and symptom measures and global functioning measures. No association was found between the quality of the childs perception of the therapeutic relationship and treatment outcome. Clinical implications are discussed.

The aim of the present study was to evaluate the psychometric properties of the Competence and Adherence Scale for Cognitive Behavioral Therapy (CAS-CBT). The CAS-CBT is an 11-item scale developed to measure adherence and competence in cognitive-behavioral therapy (CBT) for anxiety disorders in youth. A total of 181 videotapes from the treatment sessions in a randomized controlled effectiveness trial (Wergeland et al., 2014) comprising youth (N = 182, M age = 11.5 years, SD = 2.1, range 8-15 years, 53% girls, 90.7% Caucasian) with mixed anxiety disorders were assessed with the CAS-CBT to investigate interitem correlations, internal consistency, and factor structure. Internal consistency was good (Cronbachs alpha = .87). Factor analysis suggested a 2-factor solution with Factor 1 representing CBT structure and session goals (explaining 46.9% of the variance) and Factor 2 representing process and relational skills (explaining 19.7% of the variance). The sum-score for adherence and competence was strongly intercorrelated, r = .79, p < .001. Novice raters (graduate psychology students) obtained satisfactory accuracy (ICC > .40, n = 10 videotapes) and also good to excellent interrater reliability when compared to expert raters (ICC = .83 for adherence and .64 for competence, n = 26 videotapes). High rater stability was also found (n = 15 videotapes). The findings suggest that the CAS-CBT is a reliable measure of adherence and competence in manualized CBT for anxiety disorders in youth. Further research is needed to investigate the validity of the scale and psychometric properties when used with other treatment programs, disorders and treatment formats. (PsycINFO Database Record

A substantial number of children with anxiety disorders do not improve following cognitive behavioral therapy (CBT). Recent effectiveness studies have found poorer outcome for CBT programs than what is typically found in efficacy studies. The present study examined predictors of treatment outcome among 181 children (aged 8-15 years), with separation anxiety, social phobia, or generalized anxiety disorder, who participated in a randomized, controlled effectiveness trial of a 10-session CBT program in community clinics. Potential predictors included baseline demographic, child, and parent factors. Outcomes were as follows: a) remission from all inclusion anxiety disorders; b) remission from the primary anxiety disorder; and c) child- and parent-rated reduction of anxiety symptoms at post-treatment and at 1-year follow-up. The most consistent findings across outcome measures and informants were that child-rated anxiety symptoms, functional impairment, a primary diagnosis of social phobia or separation anxiety disorder, and parent internalizing symptoms predicted poorer outcome at post-treatment. Child-rated anxiety symptoms, lower family social class, lower pretreatment child motivation, and parent internalizing symptoms predicted poorer outcome at 1-year follow-up. These results suggest that anxious children with more severe problems, and children of parents with elevated internalizing symptom levels, may be in need of modified, additional, or alternative interventions to achieve a positive treatment outcome.
