Brief Summary

The Unified Protocol (UP) is an emotion-focused, cognitive-behavioural intervention that is developed to target core temperamental characteristics underlying anxiety and depressive disorders. Ehrenreich and colleagues developed UP for adolescents (UP-A). The current study aims at evaluating efficacy of UP-A for the treatment of emotional disorders in Chinese adolescents in Hong Kong.

The current study would recruit 27 Chinese-speaking patients, age 13 to 18, with a primary diagnosis of any Diagnostic and Statistical Manual (Fifth edition) anxiety disorders and/or depressive disorder. They would be randomized into one of the two treatment arms, namely UP-A treatment condition (UP-A), and treatment-as-usual (TAU) condition. Following randomization, participants in the UP-A condition would attend individual treatment based on UP-A, which last for 10 to 12 weeks. Participants in the TAU condition would be provided with usual clinical psychological service (i.e. treatment as usual) in the first 12 weeks before they start attending the same individual treatment program.

Primary outcomes would be patient's self-rated measures on clinical symptoms, and secondary outcomes would be their clinical diagnoses, parent-rated and other self-rated measures. It is hypothesized that, comparing to those in TAU, participants in the UP-A condition would show improvements in depressive symptoms, anxiety symptoms and functional impairment at the end of treatment. When the outcomes of all participants are combined, it is hypothesized that participants will show demonstrate improvement in depressive symptoms, anxiety symptoms, and functional impairment after completing the UP-A and at the 3-month follow-up.

Detailed Description

A Chinese treatment protocol would be developed based on the UP-A. The adolescent program consists of 8 modules, and the parent program consists of 3 modules. Similar to the work by Ehrenreich and Barlow, a flexible modular approach would be adopted, when extra sessions would be arranged to cater for individual treatment needs and heterogeneity of symptom severity. The whole treatment comprised of 10 to 12 individual sessions for the adolescents, and 4 to 6 sessions for parents or guardian. The total duration would be around 3 months. Each treatment sessions would be around 1 hour.

Unified protocol for adolescents (UP-A)Unified protocol for adolescents (UP-A)The Unified Protocol (UP) is an emotion-focused, cognitive-behavioural intervention that is developed to target core temperamental characteristics underlying anxiety and depressive disorders. The goal of the UP is to help patients to cultivate a greater willingness to experience uncomfortable emotions and to reduce maladaptive emotion response tendencies, so as to lessen the intensity and frequency of uncomfortable emotions. Ehrenreich and colleagues modified from the original UP and developed the UP for adolescents (UP-A). A Chinese treatment protocol would be developed based on the UP-A. Contents of the treatment includes motivational enhancement, psychoeducation of emotion, avoidance and emotion driven behaviours, interoceptive exposure, cognitive reappraisal, emotion awareness training and emotion exposure. It consists of 10 to 12 individual sessions for the adolescents, and 4 to 6 sessions for parents or guardians.
Treatment as usual (TAU)Treatment as usual (TAU)TAU participants will receive usual clinical psychological service provided in the clinic (i.e. treatment as usual) in the first 12 weeks, before they start receiving same individual treatment program based on UP-A.
Primary Outcome Measures
NameTimeMethod

* One of the inventories in the Beck Youth Inventories of Emotional and Social Impairment (Second Edition, Chinese version).

* Construct measured: depressive symptoms.

* Total scores would be converted into T-scores (range from 20-81) and descriptive classifications (normal, mild, moderate and severe) according to aged-norm.

* The higher the T-scores, the more severe the depressive symptoms.

Change of anxiety symptoms from baseline to treatment completion and at the three-month follow-upUP-A: Week 0 (pre-treatment), Week 12 (post-treatment) and Week 24 (follow-up); TAU: Week 0 (baseline), Week 12 (pre-treatment), Week 24 (post-treatment) and Week 36 (follow-up)

Youth Self-report (YSR; 1991 \& 2001 combined version, Chinese edition)

A Total Competence Scale is computed from subscale scores, and would be converted into T-scores (range from 10-80). Descriptive classifications (normal, borderline and clinical) would be obtained from T-scores. The higher the T-score, the higher the competence.

Descriptive classifications (normal, borderline and clinical) would be obtained from T-scores. The higher the T-score, the higher the competence.

* The problem scale consists of the internalizing and externalizing problem subscales. Subscale total scores would be converted into T-scores (range from 29-100). A Total Problem Scale is computed from problem items, and would be converted into T-scores (range from 23-100). Descriptive classifications (normal, borderline and clinical) would be obtained from T-scores. The higher the T-score, the more severe the problems.
