Cognitive models propose that biased information processing in social anxiety (SA) and depression facilitates negative and inhibits the processing of positive self-information. These biases are postulated to reinforce persistent negative views of the self. Biased updating of self-beliefs in response to valanced new information in both SA and depression is theoretically postulated. The results, however, are not fully consistent with theoretical postulations. Importantly, self-information is structured around two main domains - agency (e.g., competence, assertiveness) and communion (e.g., warmth, connectedness). These domains distinctly influence the way information about the self is processed and integrated. However, this distinction is missing from the examination of self-belief updating. The current study examined how individuals update agentic and communal self-beliefs in response to negative and positive social feedback. We employed a novel ‘SocialMirror’ paradigm in a large subclinical sample (N = 560). In this two-phase reversal learning task, participants received negative feedback followed by positive feedback on their personality traits. SA was uniquely associated with increased negative updating of agentic, but not communal, self-beliefs. Depression was uniquely associated with reduced positive updating across both domains. Notably, these findings remained evident even after statistically controlling for initial beliefs. Across the sample, updating was domain dependent, with agentic traits being less malleable. These findings suggest domain- and valence-related patterns of self-belief updating in SA and depression. Results are interpreted in light of Bayesian models, emphasizing the need to integrate motivational aspects into cognitive theory. We highlight the implications of these findings for interventions aimed at updating self-belief in psychopathology.

认知模型表明，社交焦虑和抑郁的偏倚信息加工促进了消极自我信息的加工，抑制了积极自我信息的加工。这些偏见被认为是为了强化对自我的持续负面看法。在SA和抑郁症中，有偏见的自我信念更新是对有价值的新信息的反应，理论上是假设的。然而，结果并不完全符合理论假设。重要的是，自我信息是围绕两个主要领域构建的——代理（例如，能力、自信）和交流（例如，温暖、联系）。这些领域明显地影响着关于自我的信息被处理和整合的方式。然而，这种区别在自我信念更新的研究中是缺失的。目前的研究考察了个人如何在回应消极和积极的社会反馈时更新个人和群体的自我信念。我们在一个大型亚临床样本（N = 560）中采用了一种新颖的“SocialMirror”范式。在这个两阶段的逆向学习任务中，参与者先收到关于他们性格特征的负面反馈，然后收到正面反馈。SA与主观自我信念的负面更新增加有独特的关联，而与集体自我信念无关。抑郁症与这两个领域的积极更新减少有独特的联系。值得注意的是，即使在统计上控制了初始信念之后，这些发现仍然很明显。在整个样本中，更新是领域依赖的，代理特征的可塑性较小。这些发现提示了SA和抑郁症中自我信念更新的域和价相关模式。结果根据贝叶斯模型解释，强调需要将动机方面整合到认知理论中。我们强调这些发现对旨在更新精神病理学自我信念的干预措施的意义。

Value-based decisions are often biased by Pavlovian cues in the environment, but it remains unclear how such biases affect optimal decision-making in humans. To address this, we used a novel variant of the Pavlovian-to-Instrumental Transfer (PIT) paradigm. Participants first learned to prefer a richer option (70 % reward probability) over a poorer one (30 %) in order to maximize rewards. A baiting rule was implemented, whereby each option's reward probability increased the longer it was not selected, rendering reward matching (i.e., aligning choice proportions with reward probabilities) a close approximation of the optimal strategy. Pavlovian cues predictive of either option were then introduced during decision-making. Results showed that Pavlovian bias disrupted optimal behavior, impairing reward maximization under both nominal extinction and rewarded conditions. This effect was replicated in an independent sample. In a third experiment, weakening the cue-outcome association during Pavlovian learning reduced the bias, suggesting a causal role of cue predictiveness. Together, these findings demonstrate that Pavlovian cues can produce maladaptive choice patterns, with implications for understanding and potentially mitigating behaviors linked to impulsivity and addiction.

基于价值的决策常常受到环境中巴甫洛夫线索的影响，但目前尚不清楚这种偏见如何影响人类的最佳决策。为了解决这个问题，我们使用了巴甫洛夫-工具迁移（PIT）范式的一种新变体。参与者首先学会了选择更富的选项（70%的奖励概率），而不是更差的选项（30%），以获得最大的奖励。我们执行了一个诱饵规则，即每个选择的奖励概率随着时间的延长而增加，从而呈现出奖励匹配（即将选择比例与奖励概率对齐）是最优策略的近似值。然后在决策过程中引入预测两种选择的巴甫洛夫线索。结果表明，巴甫洛夫偏见破坏了最优行为，损害了名义灭绝和奖励条件下的奖励最大化。这种效应在一个独立的样本中得到了重复。在第三个实验中，在巴甫洛夫学习过程中，减弱线索-结果的关联减少了偏见，表明线索预测的因果作用。总之，这些发现表明，巴甫洛夫线索可以产生不适应的选择模式，这对理解和潜在地减轻与冲动和成瘾有关的行为有影响。

Childhood maltreatment (CM), defined as caregiver-perpetrated abuse or neglect during childhood or adolescence, is associated with enduring social dysfunction. Adults with a history of CM often maintain greater interpersonal distance from both friends and strangers, regardless of relational closeness. Predictive-processing models suggest that such impairments may stem from the development of overly precise negative beliefs about others, which are resistant to updating, even in the face of contradictory information. The current study investigated whether the ability to form and update social beliefs varies as a function of CM history, and whether belief updating moderates the association between CM and posttraumatic stress disorder (PTSD) symptoms following trauma exposure in adulthood. One hundred and eighteen participants completed a battery of questionnaires and a performance-based task assessing belief formation and updating about friends and strangers. Results indicated no CM-related differences in initial belief formation. However, as predicted, adults with a CM history showed impaired belief updating when interacting with strangers. Importantly, deficits in stranger-related belief updating moderated the relationship between CM severity and PTSD symptoms: those with poor updating showed a stronger association between CM and PTSD, while those with greater flexibility in belief updating reported low symptom levels regardless of maltreatment severity. These findings suggest that CM may disrupt adaptive belief updating in interpersonal contexts, contributing to later vulnerability to psychopathology. The results highlight the potential value of targeting social cognitive processes, particularly belief updating, in interventions aimed at improving social functioning and psychological resilience among individuals with a history of CM.

儿童虐待（CM），定义为在儿童或青少年时期由照顾者实施的虐待或忽视，与持久的社会功能障碍有关。有CM病史的成年人通常与朋友和陌生人保持更大的人际距离，无论关系亲密与否。预测处理模型表明，这种损伤可能源于对他人过于精确的负面信念的发展，即使面对矛盾的信息，这种信念也不愿更新。目前的研究调查了形成和更新社会信念的能力是否随CM历史的变化而变化，以及信念更新是否调节CM与成年期创伤暴露后创伤后应激障碍（PTSD）症状之间的关联。118名参与者完成了一系列问卷调查和一项基于表现的任务，评估对朋友和陌生人的信念形成和更新。结果显示，在初始信念形成方面没有cm相关的差异。然而，正如预测的那样，有CM病史的成年人在与陌生人互动时表现出受损的信念更新。重要的是，陌生人相关的信念更新缺陷调节了CM严重程度与PTSD症状之间的关系：更新能力差的患者CM与PTSD之间的关联更强，而信念更新灵活性更强的患者无论虐待严重程度如何，其症状水平都较低。这些发现表明，CM可能会破坏人际环境中的适应性信念更新，从而导致后来对精神病理的脆弱性。研究结果强调了针对社会认知过程的潜在价值，特别是信念更新，旨在改善有CM病史的个体的社会功能和心理弹性。

Background

Effective treatments for anorexia nervosa (AN) are available, yet many patients do not respond to treatment or experience relapse. Cognitive bias modification aims to ameliorate cognitive biases that are assumed to contribute to the development and maintenance of AN. This study examines the efficacy of a novel mobile approach-avoidance bias modification training (ABMT) with food cues for AN.

Method

In this RCT, 90 inpatients with AN received six sessions of active or sham ABMT with food cues or no training, alongside treatment-as-usual. Primary outcome was self-reported eating disorder psychopathology; secondary outcomes included food-related approach-avoidance bias, fear of food, and BMI. Outcomes were assessed at baseline, end-of-training and at 6-month follow-up.

Results

Active ABMT did not result in greater reductions in eating disorder psychopathology. Similarly, treatment conditions did not differ regarding in change in BMI, approach-avoidance bias or fear of food, neither in the short term nor in the long term. Changes in approach-avoidance bias did not mediate training effects on any outcomes.

Conclusions

This first RCT on ABMT for AN found no superiority of active ABMT over sham or no ABMT in reducing eating disorder psychopathology. ABMT also appeared insufficient to alter food-related approach bias. Mobile ABMT with food cues in its current form does not seem to be an efficacious adjunct treatment to inpatient TAU for patients with AN. Further research may explore whether modified training protocols and personalized approaches are more promising in this regard.

背景：神经性厌食症（AN）有有效的治疗方法，但许多患者对治疗没有反应或复发。认知偏差修正旨在改善认知偏差，认知偏差被认为有助于神经网络的发展和维持。本研究探讨了一种新的移动方法-带有食物线索的回避偏见修正训练（ABMT）对AN的有效性。方法：在这项随机对照试验中，90名AN住院患者在常规治疗的同时，接受了6次有食物提示或无训练的主动或假ABMT治疗。主要结局是自我报告的饮食失调精神病理；次要结局包括与食物相关的方法避免偏差、对食物的恐惧和体重指数。在基线、训练结束和6个月随访时评估结果。结果：主动ABMT并没有导致进食障碍精神病理的更大减少。同样，无论是短期还是长期，治疗条件在BMI、方法回避偏见或对食物的恐惧方面都没有差异。方法回避偏差的改变并没有调节训练对任何结果的影响。结论：这是第一项针对AN的ABMT的随机对照试验，在减少饮食障碍精神病理方面，活性ABMT没有比假ABMT或不ABMT有优势。ABMT似乎也不足以改变与食物相关的方法偏差。目前形式的带有食物线索的移动ABMT似乎不是an患者住院TAU的有效辅助治疗。进一步的研究可能会探索改进的训练方案和个性化的方法是否在这方面更有希望。试验注册：本研究的设计已在德国临床试验注册网站[https://trialsearch.who.int/Trial2.aspx?TrialID=DRKS00022078]]注册。

Background

Borderline personality disorder (BPD) can be treated successfully with specific psychological treatments, but there is no clear evidence of superiority of one specific treatment at the group level. Due to high heterogeneity in BPD, individual patients might benefit differently from specific treatments.

Methods

Based on a randomised trial comparing 18 months of dialectical behaviour therapy (DBT) and schema therapy (ST) for BPD, differential effectiveness was examined using causal forest analyses. Baseline variables on BPD criteria, general psychopathology, traumatic childhood experiences, rejection sensitivity, level of functioning, coping skills, schemas and medication were included to predict the Borderline Personality Disorder Severity Index (BPDSI-IV) during treatment and follow-up (24 and 30 months after start of treatment).

Results

A subgroup was identified that benefited significantly more from DBT compared to ST. This group showed a significantly greater reduction in symptoms post treatment (post-treatment difference of 5.79 BPDSI points, SMD = 0.65, p = .028), but no longer at follow-up (p = .771). The group that showed better results with DBT displayed a pattern of specific baseline characteristics: higher levels of functioning, less frequent emotional neglect and sexual abuse, more severe anxiety symptoms and more pronounced schema ’failure to achieve’. No pattern of variables was identified associated with a superiority of ST.

Conclusion

Moderators of the short-term effect of DBT versus ST were found. However, this moderator effect was no longer significant at follow-up. Identifying patient characteristics associated with differential treatment effect might be a promising way to improve BPD treatment outcomes faster.

边缘型人格障碍（BPD）可以通过特定的心理治疗成功治疗，但没有明确的证据表明一种特定的治疗方法在群体水平上具有优势。由于BPD的高度异质性，个体患者可能从特定治疗中获益不同。方法基于一项比较18个月辩证行为疗法（DBT）和图式疗法（ST）治疗BPD的随机试验，使用因果森林分析来检验差异效果。在治疗和随访期间（治疗开始后24个月和30个月），包括BPD标准、一般精神病理学、创伤性童年经历、排斥敏感性、功能水平、应对技能、图式和药物治疗等基线变量来预测边缘型人格障碍严重程度指数（BPDSI-IV）。结果发现有一个亚组从DBT中获益明显多于st，该组治疗后症状的减轻明显更大（治疗后BPDSI点差异为5.79,SMD = 0.65, p = 0.028），但在随访时不再如此（p = 0.771）。在DBT中表现出较好结果的那一组表现出特定的基线特征模式：更高的功能水平，更少的情感忽视和性虐待，更严重的焦虑症状和更明显的“失败”模式。没有发现与ST的优势相关的变量模式。结论：发现了DBT与ST的短期效果的调节因子。然而，这种调节效应在随访中不再显著。识别与不同治疗效果相关的患者特征可能是更快改善BPD治疗结果的有希望的方法。回顾性注册（德国临床试验注册：DRKS00011534），未更改方案。

Social anxiety is characterized by persistent fear of social situations and has been associated with information processing biases, including aberrant memory for social information. Although social situations are rich in contextual cues, little is known about context-dependent memory processes in social anxiety. Here, context-dependent memory was studied in participants with high vs. low social anxiety. We tested whether contextual congruency between encoding and retrieval influences memory for social (faces) versus non-social (houses) stimuli. Participants (N = 231; high social anxiety n = 118, low social anxiety n = 113) completed a recognition memory task of either faces or houses presented against colored backgrounds. During a recognition test, old stimuli were presented with either encoding-congruent or incongruent background colors, along with new stimuli. Participants were asked to make old/new judgments. Memory performance was measured using sensitivity (d') scores. A significant three-way interaction between group, task, and congruency indicated that individuals with high social anxiety showed enhanced context-dependent memory specifically for faces, but not for houses. No such effect was observed in individuals with low social anxiety.

社交焦虑的特征是对社交情境的持续恐惧，并与信息处理偏见有关，包括对社交信息的异常记忆。尽管社交情境具有丰富的情境线索，但人们对社交焦虑中的情境依赖记忆过程知之甚少。在这里，情境依赖记忆在高和低社交焦虑的参与者中进行了研究。我们测试了编码和检索之间的上下文一致性是否影响社会（面孔）和非社会（房屋）刺激的记忆。参与者（N = 231，高社交焦虑者N = 118，低社交焦虑者N = 113）完成了在有色背景下的面孔或房屋的识别记忆任务。在识别测试中，将旧刺激与编码一致或不一致的背景颜色以及新刺激一起呈现。参与者被要求做出新旧判断。记忆表现用灵敏度（d'）评分来衡量。群体、任务和一致性之间显著的三向交互作用表明，高社交焦虑个体对面孔的情境依赖记忆增强，而对房屋的情境依赖记忆没有增强。在低社交焦虑的个体中没有观察到这种影响。这些发现表明，高社交焦虑个体对社会刺激表现出增强的特定情境依赖记忆效应。这种特定领域的记忆增强表明，社交焦虑中的记忆偏差至少在一定程度上是通过对上下文信息的不同处理而表现出来的。

Network theory conceptualizes mental disorders as systems of dynamic interactions among symptoms and other variables, and proposes that people with psychopathology have distinct networks as compared to healthy people. However, this idea is rarely investigated, and networks are mostly estimated on cross-sectional data. Importantly, as network theory is specified on the within-person level, it is necessary to estimate networks based on intensive time-series data. This study estimated contemporaneous and temporal transdiagnostic networks on time-series data of participants with different levels of psychopathology. 192 university students completed an Ecological Momentary Assessment (EMA) protocol. A newly developed bootstrap method was used to compare the multi-level Vector Autoregressive (mlVAR) effects between groups. Network connectivity did not differ between groups. Only a few edges differed significantly between groups, with small effect sizes. These results suggest that networks of groups of people with different levels of psychopathology might not differ. Explanations and implications for these results, such as the impact of focusing on heterogeneous groups instead of homogeneous groups or individuals, the relevance of node levels, and methodological and analytical decisions, are discussed.

网络理论将精神障碍概念化为症状和其他变量之间动态相互作用的系统，并提出精神病理患者与健康人相比具有不同的网络。然而，这种想法很少被调查，网络大多是根据横截面数据估计的。重要的是，由于网络理论是在个人层面上规定的，因此有必要基于密集的时间序列数据来估计网络。本研究估计了不同精神病理水平的参与者在时间序列数据上的同期和时间跨诊断网络。192名大学生完成了生态瞬时评估（EMA）协议。采用一种新开发的自举方法比较了组间多级向量自回归（mlVAR）效应。两组之间的网络连接没有差异。两组之间只有少数边缘有显著差异，效应量很小。这些结果表明，不同精神病理水平的人群之间的网络可能没有差异。讨论了这些结果的解释和含义，例如关注异质群体而不是同质群体或个人的影响，节点级别的相关性以及方法和分析决策。

Does treating emotional memories come at a price? Effects of single-session EMDR, imaginal exposure, and imagery rescripting on forced-choice recognition of event details in healthy adults – a laboratory study 治疗情感记忆是有代价的吗？一项实验室研究：单次EMDR、图像暴露和图像描述对健康成人事件细节强制选择识别的影响

Eye Movement Desensitization and Reprocessing (EMDR), Imaginal Exposure (IE), and Imagery Rescripting (ImRs) are effective trauma-focused interventions. However, concerns persist that they may impair the accuracy of memories addressed in treatment. This laboratory study tested whether a single session of EMDR, IE, or ImRs affects forced-choice recognition in healthy adults.

Two hundred sixty-five participants underwent the Trier Social Stress Test (TSST) and received EMDR, IE, ImRs, or no intervention (NIC) the following day. One week later, memory for the TSST was assessed using a forced-choice recognition task (one target; three plausible foils).

Contrary to expectations, the interventions did not differentially affect recognition performance; the number of correct answers was comparable to NIC across intervention groups. For ImRs and IE, this aligns with recent findings suggesting that they do not impair recognition memory. For EMDR, prior experimental studies linked eye movements to poorer delayed free recall, stimulus discrimination, and yes/no recognition. Here, we observed no impairment in delayed forced-choice recognition, suggesting that previously reported negative effects may not generalize across memory outcomes or task formats.

Overall, these findings indicate that trauma-focused interventions do not carry a general risk of memory impairment. However, conclusions are limited by the laboratory analogue design, exclusive reliance on a recognition task, and the absence of treatment-integrity checks, which raises the possibility that null effects reflect limited intervention effectiveness. Future research should specify conditions under which these interventions may pose risks, clarify mechanisms underlying task- and memory-specific effects, and examine how findings generalize to clinical populations.

眼动脱敏和再处理（EMDR）、图像暴露（IE）和图像处方（ImRs）是有效的创伤聚焦干预措施。然而，人们仍然担心它们可能会损害治疗中记忆的准确性。本实验室研究测试了单次EMDR、IE或ImRs是否会影响健康成人的强迫选择认知。265名参与者接受了特里尔社会压力测试（TSST），并在第二天接受了EMDR、IE、ImRs或无干预（NIC）。一周后，使用强迫选择识别任务（一个目标；三个似是而非的目标）评估TSST的记忆。与预期相反，干预措施对认知表现没有显著影响；各干预组的正确答案数量与NIC相当。对于imr和IE，这与最近的研究结果一致，表明它们不会损害识别记忆。对于EMDR，先前的实验研究将眼球运动与较差的延迟自由回忆、刺激辨别和是/否识别联系起来。在这里，我们没有观察到延迟强迫选择识别的损害，这表明先前报道的负面影响可能不会在记忆结果或任务格式中普遍存在。总的来说，这些发现表明，以创伤为重点的干预并不会带来记忆障碍的一般风险。然而，结论受到实验室模拟设计，完全依赖于识别任务以及缺乏治疗完整性检查的限制，这增加了无效效应反映有限干预有效性的可能性。未来的研究应该明确这些干预措施可能带来风险的条件，阐明任务和记忆特定效应的潜在机制，并检查研究结果如何推广到临床人群。

Background

African American or Black adults who use cannabis face significant cannabis-related health disparities, including more frequent cannabis use and higher rates of Cannabis Use Disorder (CUD) relative to non-Hispanic/Latinx White adults who use cannabis. This highlights the need for accessible, culturally tailored interventions that address the unique needs of Black adults with CUD. This study evaluated the feasibility, utilization, acceptability, and initial efficacy of a culturally tailored mobile intervention (Culturally Tailored-Mobile Integrated Cannabis and Anxiety Reduction Treatment [CT-MICART]), integrating false safety behavior (FSB) reduction or elimination skills with use reduction or cessation skills.

Methods

Participants (N = 50, 50.0% female, M_age = 42.9 years, SD = 10.7) were randomized to: 1) CT-MICART + ecological momentary assessments (EMAs) or 2) EMAs-only for a period of 6-weeks. Feasibility outcomes included enrollment, retention, and EMA completion rates, and utilization was assessed via app feature engagement. Acceptability was evaluated via self-reported app satisfaction, and preliminary efficacy was examined by testing changes in cannabis use outcomes.

Results

Results indicated strong feasibility, high utilization, and positive acceptability. Participants in the CT-MICART + EMA group demonstrated statistically significantly lower cannabis use frequency rates and less time spent intoxicated from cannabis compared to the EMA-only group. No significant effects were observed for cannabis-related problems, CUD severity, or FSB use at the 6-week follow-up.

Conclusion

This study provides initial evidence for the feasibility, acceptability, and efficacy of CT-MICART + EMA for certain cannabis use processes among Black adults with probable CUD. Larger trials are necessary to test whether CT-MICART holds potential as a scalable solution to support use reduction or cessation goals for this population.

背景：使用大麻的非裔美国人或黑人成年人面临着与大麻相关的重大健康差异，包括与使用大麻的非西班牙裔/拉丁裔白人成年人相比，更频繁地使用大麻和更高的大麻使用障碍（CUD）率。这突出了需要采取可获得的、适合文化的干预措施，以解决患有CUD的黑人成年人的独特需求。本研究评估了一种文化定制的移动干预（文化定制-移动大麻和焦虑减少综合治疗[CT-MICART]）的可行性、利用、可接受性和初步疗效，该干预将减少或消除虚假安全行为（FSB）的技能与减少或停止使用的技能相结合。方法：参与者（N = 50，女性50.0%，年龄42.9岁，SD = 10.7）随机分为：1)CT-MICART +生态瞬时评估（EMAs）或2)仅EMAs，为期6周。可行性结果包括注册、保留和EMA完成率，并通过应用功能参与评估使用率。通过自我报告的应用程序满意度来评估可接受性，通过测试大麻使用结果的变化来检查初步疗效。结果：结果可行性强，利用率高，可接受性好。与仅使用EMA的组相比，CT-MICART + EMA组的参与者表现出统计学上显著降低的大麻使用频率和更少的大麻中毒时间。在6周的随访中，没有观察到大麻相关问题、CUD严重程度或FSB使用的显著影响。结论：本研究为CT-MICART + EMA在可能患有CUD的黑人成人中某些大麻使用过程的可行性、可接受性和有效性提供了初步证据。需要更大规模的试验来检验CT-MICART是否有潜力作为一种可扩展的解决方案来支持这一人群的减少使用或戒烟目标。

Despite the evidence in favour of Triple P for Baby (TPB), a parenting intervention to support parents at the transition to parenthood in high-income countries, little is known about whether the program would be efficacious in enhancing parenting skills and alleviating psychological distress among women in low-and middle-income countries. This randomised controlled trial evaluated the efficacy of TPB in Kenya with an urban-based sample of 82 pregnant women with depressive symptoms randomly assigned to the intervention (TPB) or standard care as usual (CAU) conditions. The intervention was delivered prenatally in four group sessions, and postnatally through four individually tailored telephone sessions. Participants were assessed at three-time points, and 90 % of participants were retained at follow-up. We applied intention-to-treat analysis and found improvements in maternal responsiveness and parental confidence and reductions in depressive and anxiety symptoms for mothers in the TPB group relative to the CAU group. There were no between-group differences in maternal self-efficacy. Infants of mothers in the TPB group had better outcomes for attaining fine motor and receptive language milestones compared to infants of mothers allocated to CAU. The findings of this trial indicate that Triple P for Baby is an efficacious early parenting intervention for women with depressive symptoms in low-resource settings.

尽管有证据支持“婴儿三重P”（Triple P for Baby， TPB），这是一种在高收入国家支持父母向为人父母过渡的育儿干预措施，但人们对该计划是否能有效提高低收入和中等收入国家妇女的育儿技能和减轻心理困扰知之甚少。这项随机对照试验评估了TPB在肯尼亚的疗效，以城市为基础的82名有抑郁症状的孕妇为样本，随机分配到干预组（TPB）或常规标准治疗组（CAU）。干预在产前通过四组会议进行，在产后通过四次单独定制的电话会议进行。参与者在三个时间点进行评估，90%的参与者在随访中被保留。我们应用意向治疗分析发现，与CAU组相比，TPB组母亲的反应性和父母信心有所改善，抑郁和焦虑症状有所减轻。母亲自我效能感组间无差异。与母亲被分配到CAU组的婴儿相比，母亲被分配到TPB组的婴儿在达到精细运动和接受性语言里程碑方面有更好的结果。本试验的结果表明，婴儿三重P是一个有效的早期育儿干预妇女抑郁症状在低资源环境。
