Filter by:The goal of this clinical trial is to the efficacy of the Building a Strong Identity and Coping Skills intervention within a sample of low-income and minoritized youth aged 11-14 who are seeking mental health treatment and have been placed on a waitlist to receive services. The aims of this study are to: (1) confirm the efficacy of BaSICS by replicating previous findings, (2) Examine the changes of coping mechanisms and symptom change over the course of the BaSICS intervention, and (3) test models of physiologic stress reactivity and regulation to capture biological "risk" and recalibration. Cohorts of 20 participants will randomly be enrolled in either the intervention (10) or control (10) groups. Participants enrolled in the intervention group will complete the BaSICS program and participants enrolled in the no intervention group will not be enrolled in the intervention program. The BaSICS program is designed to help treat anxiety, depression, and post-traumatic stress symptoms and disorders and have direct effects on physiologic stress response systems (hypothalamic-pituitary-adrenal (HPA) axis). Researchers will compare the intervention and no intervention groups to see if there is a difference in the reduction of markers for anxiety, depression, and suicide scores, changes in coping mechanism, and HPA reactivity profiles
The persistent political conflicts and COVID-19 pandemic have led to elevated chronic stress levels in Hong Kong, with far-reaching and profound negative impacts on the citizen's mental health. An important pathway via which chronic stress negatively impacts health is through promoting high-risk behaviours, such as addiction, suicide, and antisocial acts. Therefore, testing means to break the association between chronic stress and high-risk behaviour is essential to reducing the adverse consequences of stress and promoting stress resilience. The transcranial direct current stimulation (tDCS) may be a viable method for reducing risky tendency in high-stress individuals, through modulating brain functions and plasticity. Although single-session tDCS has been shown to reliably reduce risky decision making and behaviours acutely, its efficacy over extended periods of time has not been demonstrated, particularly among non-clinical samples. Being able to show that tDCS could lead to long-lasting reduction of risky tendency is necessary for promoting the wide application of this method in therapeutic settings. In this project, we aim to conduct a randomised control trial to systematically and comprehensively test whether 10 sessions of tDCS on either the dorsolateral prefrontal cortex or the orbitofrontal cortex would lead to reduction in risky tendency not only immediately after treatment, but also at 1 month and 3 months after treatment. Participants will be healthy male and female adults (21-40 years old) under relatively high levels of chronic stress, as selected from an online survey prior to the study. Participants will be randomly allocated to one of 3 treatment groups: DLPFC tDCS, OFC tDCS, and sham control. At baseline, participants will complete several risk-taking assessments, including an established computerised task that measures both risk taking and a cognitive bias that was shown to increase irrational risky tendency (illusion of control), an established questionnaire that measures risky decision making in real-life scenarios, and a scale measuring past engagement in common risky activities. Participants will also complete various personality and mood questionnaires, along with assessments on important cognitive abilities. We hypothesized that both DLPFC and OFC tDCS would reduce risk taking across the 3 timepoints, but the effect of DLPFC tDCS would be mediated by reduction in cognitive bias, whereas that of OFC tDCS would be mediated by increase in inhibition functions. These hypotheses will be tested by linear mixed models and mediation analyses. Additional exploratory analyses also test whether the tDCS effect would be moderated by relevant personality factors such as impulsivity.
