跨诊断脑行为分析以增强认知行为治疗反应
研究概览
详细说明
重度抑郁症 (MDD) 和广泛性社交焦虑症 (gSAD) 是普遍存在的主要公共卫生问题。 这些疾病的特点是情绪失调,无法或无效率地调节消极和积极的影响,如常见的和特定于疾病的症状(例如,对消极刺激的注意力偏向、过度/不适当的消极想法、过度兴奋、快感缺乏、情绪迟钝)。 这种失调被认为是由于自上而下的“情绪调节”(ER)额叶节点之间的不平衡造成的(耀斑)网络。 因此,成功的治疗有望使 FLARES 网络中的神经功能紊乱“正常化”,这可以通过 fMRI 和更远端的脑功能单元进行测量——来自脑电图的事件相关电位 (ERP),来自肌电图 (EMG) 的惊吓增强,神经认知表现,以及通过自我报告在日常生活中使用调节策略。 拟议研究的总体目标是了解 CBT 如何、何时、何地起作用,以及为谁量身定制治疗以改善临床结果。
如果没有精确确定的变化“目标”和“预测因子”,CBT 反应将继续不可预测地变化,很少有人实现有意义的临床改善,使他们处于复发和复发的风险中。 我们的建议建立在我们实验室和其他实验室发布的数据和初步数据的基础上,这些数据显示 FLARES 功能,如 fMRI、ERP、EMG 和行为所测定的那样,对 CBT 后的变化很敏感。
重要的是,基线 fMRI 和非 fMRI 脑行为测量单位都比基线临床测量更好地预测 CBT 反应。 这些知识可以导致更精确的干预,旨在利用 CBT 之前可能存在的“优势”或改善“缺陷”和/或解释为什么 CBT 对某些患者不起作用。 fMRI(“机械”)和非 fMRI(“实用”)预测因子和治疗变化指标的双重发展旨在推进精准医学,同时增加“生物标志物”在门诊环境中的临床效用。 出于这个目标,我们建议在 MDD 和 gSAD 中的负面刺激、奖励过程和恐惧系统的背景下采用经过充分验证的范例来测试 ER 和 EG,以描述常见的和特定于疾病的变化机制和 CBT 结果的预测因子。 我们将招募 200 名患者:100 名 MDD(无共病 gSAD)、100 gSAD(无共病 MDD)并将他们随机分配至 12 周的手动 CBT 或 12 周的“安慰剂”心理治疗(支持疗法)(1:1 比例)。 将在治疗前(第 0 周)、治疗期间(中途/第 6 周)和治疗后(第 12 周)收集所有患者的 FLARES 功能的多个单位,以确定 CBT“剂量”效应,并收集 40 名健康对照者进行比较。 基于二元(反应者/非反应者状态)和连续(变化程度)结果的 CBT 前预测因子将在中途(第 6 周)、治疗后立即(第 12 周)和 6 个月随访时进行检查。

有源比较器:CBT
The clinical psychologist will use a manualized CBT approach tailored to MDD or gSAD.
Over a 12-week period sessions will include core CBT strategies -- psychoeducation, cognitive intervention (e.g., cognitive restructuring), behavioral changes (i.e., fear exposure, behavioral activation strategies) and relapse prevention.
|
CBT 通过关注所持有的思想、形象、信念和态度(一个人的认知过程)以及这些过程如何与一个人的行为方式相关联来改变人们的态度和行为,作为处理情绪问题的一种方式。

安慰剂比较:ST
The clinical psychologist will use an ST approach that resembles client-centered therapy of Carl Rogers (1951) which has been used as a control psychotherapy.
The manual is based on supportive psychotherapy principles.
Over a 12-week period, sessions will emphasize reflective listening and elicitation of affect.
In contrast to CBT, therapists allow patients to determine the focus of each session, pulling for emotion, validating emotions when possible, and offering empathetic comments.
Therapists will refrain from delineating any CBT theoretical framework and avoided cognitive and behavioral techniques that might overlap with CBT.

Changes in Symptom Severity From Baseline to Week 12 Between Treatment Arms
大体时间:baseline and week 12
|
Patients were randomized to either 12 weeks of cognitive behavioral therapy or supportive therapy.
Healthy control (HC) participants did not receive treatment but completed the same assessments at the same time points as patients.
Liebowitz Social Anxiety Scale (LSAS) and Hamilton Depression Rating Scale (HDRS) served as primary outcome measures as they are interviewer based standard clinical measures.
A composite score combining LSAS and HDRS was constructed using proportion of maximum scaling (POMS) method to represent symptom severity.
Higher scores mean worse outcomes.
The minimum value is 0 and the maximum value is 1.

Baseline Brain Activity During Emotion Regulation Differences Between Controls and Patients
大体时间:baseline
|
Outcomes are parameter estimates (arbitrary units) of brain activity for a priori brain regions of interest (bilateral amygdala, bilateral dorsolateral prefrontal cortex ('DLPFC'), bilateral inferior frontal gyrus ('IFG')) comparing brain activity during task conditions against a baseline condition (look at neutral images; 'Look Neut').
Task conditions are reappraising negative images ('Reappraise') and looking at negative images ('Look Neg').
The Reappraise vs. Look Neut and Look Neg vs. Look Neut are the contrasts of interest.
Not all participants who consented to the study completed this task at all time points.
Reasons include dropping out of the study, COVID shutdowns, scheduling issues, and participants not consenting to perform task due to use of negative images.
Higher values represent greater activation.

Comparisons Between Emotion Regulation Task Brain Activity at Baseline and After Completing Therapy (12 Weeks).
大体时间:baseline and 12 weeks
|
Planned comparisons (i.e., paired t-test).
Outcomes are parameter estimates (arbitrary units) of brain activity for a priori brain regions (amygdala, dorsolateral prefrontal cortex (DLPFC), inferior frontal gyrus (IFG)) comparing reappraising negative images ('Reappraise') to baseline condition (look at neutral images; 'Look Neut').
Not all participants who consented to the study completed this task at all time points.
Reasons include dropping out of the study, COVID shutdowns, scheduling issues, and participants not consenting to perform task due to use of negative images.
Higher values represent greater activation.

Baseline Brain Activity During Emotion Regulation as a Predictor of Psychotherapy Outcome Collapsed Across Treatment Arm.
大体时间:baseline
|
Outcomes are baseline parameter estimates (arbitrary units) of brain activity for a priori brain regions of interest (bilateral amygdala, bilateral dorsolateral prefrontal cortex ('DLPFC'), bilateral inferior frontal gyrus ('IFG')) comparing active conditions against 'baseline' condition (i.e., look at neutral images; 'Look Neut').
Active conditions are reappraising negative images ('Reappraise') and looking at negative images ('Look Neg').
The Reappraise vs. Look Neut and Look Neg vs. Look Neut are the contrasts of interest.
Other outcome measure is symptom severity before and after psychotherapy collapsing across cognitive behavioral therapy and supportive therapy to examine general psychotherapy predictors across psychotherapies.
Higher values (arbitrary units) represent greater activation.
Aim 5 is a continuation of Aim 4 including symptom measures comprised of HAMD and LSAS composite score of maximum scaling method.

Baseline Brain Activity During Emotion Regulation as a Predictor of Psychotherapy Outcome Collapsed Across Treatment Arm.
大体时间:baseline and 12 weeks
|
This aim is connected to Aim 4 and represents an additional predictor in the regression model.
Data analysis results for Aim 4 apply to this data as well.
Outcome measure is symptom severity before and after psychotherapy collapsing across cognitive behavioral therapy and supportive therapy.
Symptom measures comprised social anxiety (LSAS) and depression (HAMD) composite score proportion of maximum scaling method which ranges from 0 to 1. Higher symptom severity scores represent worse symptoms.
