The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders Among Japanese Children: A Pilot Study

A Systematic Review Comparing Four Transdiagnostic Programmes for School-Age Children

Transdiagnostic programmes are useful for helping people with internalizing symptoms and comorbid psychopathology. These programmes have as their basic idea that disorders are not separate entities but share common aetiological and maintenance processes. Their use is important with children, who tend to present less differentiated psychopathological manifestations than adults. This systematic review aimed to examine the effectiveness of four evidence-based transdiagnostic programmes: FRIENDS, Pyramid Club, Unified Protocol for Children (UP-C) and Super Skills for Life (SSL). Studies from 2018 to 2023 including children between 4 and 14 years of age were examined. Following PRISMA guidelines, 48 studies that met the inclusion criteria were considered. Most of the studies referred to treatment, only a few used the selected transdiagnostic programmes for prevention, most notably FRIENDS and SSL. Very few of the studies reviewed have been randomized controlled trials, limiting the possibility to examine incremental benefits of these programmes over alternative approaches. The findings show that all programmes showed evidence of effectiveness, but UP-C and SSL appear to be the most promising transdiagnostic programmes for the prevention and treatment of anxiety and depression in children as supported by more numerous studies in recent years. Moreover, UP-C and SSL specifically appeared effective in reducing externalizing problems and improving social skills and prosocial behaviour. Although the results presented are promising, they should be regarded as provisional and in need of further support in randomized controlled trials to test the effectiveness of these evidence-based programmes to ensure the psychological well-being of children and thus reduce healthcare costs.

Feasibility, Acceptability, and Preliminary Efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents in China: A Pilot Study

Currently, there is a lack of cost-effective and accessible intervention resources for Chinese adolescents with emotional disorders. The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A), which aims to apply transdiagnostic treatment principles to target core dysfunctions across a range of emotional disorders with a single protocol, could fill this gap. We first modified the UP-A for use in the Chinese cultural context and then assessed its feasibility, acceptability, and preliminary efficacy using a single-arm design. Twenty-four Chinese adolescents (14.1 ± 1.2 years old) with emotional disorders completed a 12-week group UP-A intervention along with their parents. Multiple outcomes were evaluated at five time points: pretreatment (T1), week 4 (T2), week 8 (T3), posttreatment (T4), and 3-month follow-up (T5). The results showed a low dropout rate (16.7%), high attendance (at 10.2 ± 1.6 sessions in adolescents and 10.7 ± 2.0 sessions in parents), and sufficient participant satisfaction. Adolescents exhibited significant decreases in emotional disorder severity (g = -1.298 to -1.341) and emotional symptoms (g = -0.440 to -1.988) and significant improvements in emotion regulation (ER) strategies, resilience, functional outcomes, and executive function. The efficacy of the intervention was significant starting at T2 and was maintained at T4 and T5. Exploratory analyses revealed that predictors of treatment outcomes included the presence of multiple comorbidities, the severity of emotional disorders, adaptive ER strategies, and resilience at T1. This study demonstrated the feasibility, acceptability, and preliminary efficacy of the Chinese version of the UP-A, and future randomized controlled trials are warranted.

The Factorial Structure, Psychometric Properties and Sensitivity to Change of the Distress Tolerance Scale for Children with Emotional Disorders

BACKGROUND

The Distress Tolerance Scale (DTS) was adapted for American and Chinese youth, but never for European youth. Moreover, the factor structures found in these previous studies were not consistent.

METHODS

The DTS was adapted for Portuguese children and then validated among 153 children aged 6-13 years with emotional disorders. A confirmatory factor analysis (CFA) was conducted; the DTS reliability and validity were analyzed, and sex and age differences were explored. A sub-sample of children who received a transdiagnostic CBT (Unified Protocol for Children) was used to analyze the DTS's sensitivity to therapeutic change.

RESULTS

The five tested models (based on previous studies) exhibited adequate fit in the CFA. However, the model previously reported for use in American children with emotional disorders was selected as the most appropriate. The DTS demonstrated adequate psychometric properties, and its validity was established through significant negative associations with measures of anxiety, depression and negative affect, as well as positive associations with positive affect. Age and sex differences were discussed. The DTS scores significantly increased from pre- to post-treatment, demonstrating sensitivity to therapeutic change.

CONCLUSIONS

The DTS is a suitable and useful measure for assessing children's distress tolerance and to assess the efficacy of CBT.

Cultural Adaptation and Implementation of Cognitive-Behavioral Psychosocial Interventions for Anxiety and Depression in Japanese Youth

The present article reviews the current status of cognitive-behavioral therapy (CBT) interventions for anxiety and depression in Japanese youth. First, a literature review of youth CBT programs for anxiety and depression is provided. Through this process, we identify which program/protocol has been most researched within Japan. Second, through a systematic interview to the authors, the development process of four predominant programs is outlined. The programs included were a family CBT program for anxiety disorders (the Japanese Anxiety Children/Adolescents Cognitive Behavior Therapy program), two school-based prevention programs for anxiety and depression (Journey of the Brave and Phoenix Time), and a transdiagnostic protocol for anxiety and depression (Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children and the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents). Third, cultural adaptation and modification of the programs are discussed from the scope of user-centered design principles as described by Lyon and Koerner (Sci Pract 23:180-200, 2016). As a result, changes in program content and material, as represented by the use of culture-friendly program names, acronyms, illustrations, and characters were endorsed in all of the programs. Structured but flexible session formats helped increase learnability and efficiency while keeping the cognitive load of providers and consumers low. A careful selection of providers, as well as quality training and consultation are important factors to maximize competency and ensure appropriate implementation. Application of existing time frames and staff who work in each setting were effective ways to increase scalability. Overall, it was shown that many of the modifications adopted overlap among successful programs; these represent the most basic and essential requirements for a program to be applicable to a wide range of contexts. Implications and further directions are explored.
