简要总结
Nearly two-thirds of ACB people living in Ontario are classified as immigrant, refugee or undocumented [non-status/NS] (IRNS) individuals. IRNS people are more likely than the general population to be exposed to events that are associated with posttraumatic stress disorder (PTSD). Furthermore, the diagnosis of HIV is itself a traumatic life event. Nonetheless, significant gaps remain regarding the best strategies for supporting trauma-informed care among ACB IRNS individuals with HIV. Accelerated Resolution Therapy (ARTh) is an exposure-based therapy that incorporates rapid eye movements in a standardized administration over 1-5 sessions. ARTh is an effective brief treatment for PTSD symptoms; but, it's range of therapeutic benefit when applied to people with co-morbid HIV infections is unknown. No studies have leveraged neuroimaging to validate the self-reported empirical therapeutic benefit of ARTh. The investigators propose to investigate the implementation of ARTh, including understanding factors influencing its therapeutic outcomes. The three specific aims of this study are to (1) identify factors influencing the response to ARTh (2) identity neuroimaging indicators for treatment effects of ARTh, and (3) to identify factors influencing ARTh implementation. The investigators will conduct a pre-/post- evaluation of intervention outcomes of ARTh implemented in a sample (n=40) of HIV-positive ACB IRNS ages 18-45 years (Aim 1). The investigators will use statistical analyses to identify factors that may moderate the treatment response of ARTh on PTSD symptoms, HIV symptoms distress and quality of life (Aim 1). The investigators will use diffusion tensor imaging and resting state functional magnetic resonance imaging (fMRI) metrics to assess structural and functional connectivity and examine their associations with PTSD symptoms and HIV symptom distress (Aim 2). Finally, the investigators will use process measures to study two specific implementation factors (acceptability and appropriateness) regarding ARTh use in this population. As a consequence of this research, the investigators expect to generate data that will be used to refine an ARTh implementation protocol that will be integrated into an adaptive implementation trial to reduce gaps in the HIV care continuum through the use of intervention packages for ACB people customized to the individual's needs.
详细描述
STUDY OVERVIEW - PURPOSE AND BACKGROUND
African, Caribbean and Black (ACB) individuals represent only 4.7% of Ontario's population, yet account for 30% of HIV prevalence in the province. Nearly two-thirds of ACB people living in Ontario are classified as immigrant, refugee or non-status (IRNS) individuals. IRNS people are more likely than the general population to be exposed to events that are associated with posttraumatic stress disorder (PTSD). Furthermore, the diagnosis of HIV is itself a traumatic life event. Nonetheless, significant gaps remain regarding the best strategies for supporting trauma-informed care among ACB IRNS individuals with HIV. For example, IRNS women are more likely than Canadian-born women to have experienced rape, non-sexual physical assault, and civil conflict. ACB IRNS men who have sex with men (MSM) are more likely than non-MSM to have emigrated to Canada as asylum-seekers after fleeing some form of persecution or imminent threat in their countries of origin. Furthermore, while it is known that stigma contributes to exacerbation and severity of HIV symptoms-via the activation of physiological stress responses-there is no known intervention that has been shown to interrupt the pathway by which HIV stigma effects stress and HIV symptoms. Accelerated Resolution Therapy (ART®) is an exposure-based therapy that incorporates rapid eye movements in a standardized administration over 5 sessions in a 3-week period. ART® is effective brief treatment for PTSD symptoms; but, it's range of therapeutic benefit when applied to people with HIV infections is unknown. Although evidence shows that the amygdala is the brain region most reactive to changes in stress stimuli, it remains unknown if therapeutic responses can be reliably validated with biomarkers. No studies have leveraged neuroimaging to validate the self-reported empirical therapeutic benefit of ART®.
The purpose of this study is to investigate the implementation of ART®, including understanding factors influencing its therapeutic outcomes.
The central hypothesis is that ART® will reduce HIV symptom distress by down-modulating the effects of stigma and posttraumatic stress-leading to improved self-reported quality of life. The hypothesis is based on previous research showing that adaptive coping strategies buffer the effects of stigma on stress, as well as evidence from a randomized trial of ART® which demonstrated statistically significant treatment effects for trauma related distress (d=1.88), anxiety (d=1.62), and depression (d=1.41), as well as a clinically meaningful 23-point reduction on the civilian PTSD checklist.[5] The investigators will investigate our central hypothesis by pursuing the following specific aims in a sample of ACB immigrant, refugee and non-status people with HIV.
- Identify factors influencing the response to ART®
- Identity neuroimaging indicators for treatment effects of ART®
- Identify factors influencing ART® implementation

排除标准
- •A person will be excluded from this study if they meet any of the following conditions:
- •born in Canada
- •unable to consent to provide documentation of HIV seropositive status
- •unable to consent to an MRI, including intolerance due to claustrophobia
- •are older than 50 years old.
- •have a major psychiatric disorder likely to impede treatment (e.g. psychosis), current suicidal ideation, current treatment for substance addiction, or diagnosis of eye movement disorder.
- •severe premorbid or comorbid psychiatric disorders. Among these exclusions are a diagnosis of schizophrenia; bipolar disorder and active depression that will confound the neurological assessments. Subjects with a mild or stable depression including those on stable tricyclic antidepressants, serotonin-reuptake antagonists, or monoamine oxidase (MAO) inhibitors are eligible to enroll.

研究组 & 干预措施
Accelerated Resolution Therapy
Participants will complete a clinical intake assessment before meeting with the therapist and initiating the ART® protocol. Participants will receive the ART intervention over a 21-day period, where imaginal exposure and imagery re-scripting will be used replace previous traumatic experiences. The ART intervention will be assessed through pre- and post-test measures at 60-days post enrolment.
干预措施: Accelerated Resolution Therapy (Other)
结局指标
主要结局
HIV Symptom Distress Scale (SDS).
时间窗: Symptom distress score 60 days post the study start date.
This 20-item instrument is used to measure overall HIV symptom frequency, distress and clinically relevant clusters. Participants are asked to indicate which of the 20 symptoms they have experienced in the past 2 weeks. Participants are then asked to rate symptom that are present, on the extent to which the symptoms are bothersome (0=do not have symptom; 25=have symptom, but no bother; 50=have symptom, little bother; 75=have symptom, bothers me some; 100= have symptom, bothers me a lot). Scores range from 0 to 100. Higher scores indicate greater symptom distress.
次要结局
- HIV Associated Neurocognitive Disease (HAND).(Composite Z-score 60 days post the study start date.)
- Working and learning memory(Composite Z-score 60 days post the study start date.)
