Augmentation of Interpersonal Psychotherapy With High-Definition Transcranial Direct Current Stimulation for Adolescent Depression

Effects of Augmentation of Interpersonal Psychotherapy With High-Definition Transcranial Direct Current Stimulation for Adolescent Depression: A Randomized Clinical Trial

Depression is among the most prevalent psychiatric disorders, with an upward trend in its manifestation in younger individuals. In contrast to adult depression, adolescent depression often presents with longer attack durations, higher recurrence rates, chronicity, and elevated disability rates. At present, treatment options for adolescent depression encompass pharmacological, physical, and psychological therapies. However, current evidence suggests that no antidepressant medication is entirely safe for youths, with only fluoxetine and escitalopram being FDA-approved for treating adolescent depression.

Given the weight of interpersonal stressors faced by teenagers, the NICE guidelines recommend interpersonal therapy(IPT) as a first-line treatment. A 2020 meta-analysis in the Journal of the American Academy of Child and Adolescent Psychiatry reported that interpersonal therapy exhibited significantly greater improvements in depression symptoms than cognitive behavioral therapy(CBT), although psychotherapeutic effects were modest, achieving a remission rate of 60%. These results underscore the need for further research to enhance interpersonal therapy's effectiveness in treating adolescent depression.

High-Definition Transcranial Direct Current Stimulation (HD-tDCS）is a highly secure non-invasive brain stimulation technique that produces sustained effects even after stimulation has discontinued, rendering it particularly valuable for therapeutic interventions. The proposed study aims to augment a single IPT treatment with HD-tDCS stimulation for adolescent depression. By enhancing the excitability of the cerebral cortex, HD-tDCS could potentially enhance IPT's therapeutic efficacy in treating adolescent depression while facilitating further investigation of its underlying neural circuit mechanisms.

Beck Scale for Suicide Ideation	Assessment of suicidal ideation. The test taker first completes the initial five questions. If the responses to both the fourth and fifth items are "no," it is considered that there is no suicidal ideation, and the questionnaire concludes. Suicidal risk is evaluated based on items six to nineteen of the scale, which assess the likelihood of actual suicidal behavior among individuals with suicidal ideation. The calculation formula for the total score is [(sum of scores for items six to nineteen) - 9) / 33] * 100, resulting in a score ranging from 0 to 100. A higher score indicates a greater risk of suicide.	Baseline

Thinc-integrated Tools(THINC-it)	THINC-it（https://progress.im/en/）is the first tool to assess cognitive functioning in MDD using both subjective and objective tests and is available as a free download for use on tablets, smartphones or computers. The tool's four objective test sections use recognized cognitive paradigms to assess subjects' performance in the key cognitive domains of attention, working memory, and executive function. The Choice Reaction Time (CRT) focuses on attention and executive function, the 1-Back Memory Task (1-Back) examines memory, attention/concentration, and executive function, the Digit Symbol Substitution Test (DSST) examines processing speed, attention, and executive function, and the Test of Connectivity B (TMT-B) assesses executive function. The 5-item Cognitive Impairment Questionnaire (PDQ⁃5⁃D) is the subjective component of the instrument and can be used to assess patients' performance in attention/concentration, planning/organization, retrospection, and prospective memory.
