Abstract

Objectives

Predictive processing approaches to belief updating in depression propose that depression is related to more negative and more precise priors. Also, belief updating is assumed be negatively biased in comparison to normative Bayesian updating. There is a lack of efficient methods to mathematically model belief updating in depression.

Methods

We validated a novel performance belief updating paradigm in a nonclinical sample (N = 133). Participants repeatedly participated in a non-self-related emotion recognition task and received false feedback. Effects of the feedback manipulation and differences in depressive symptoms on belief updating were analysed in Bayesian multilevel analyses.

Results

Beliefs were successfully manipulated through the feedback provided. Depressive symptoms were associated with more negative updating than normative Bayesian updating but results were influenced by few cases. No evidence of biased change in beliefs or overly precise priors was found. Depressive symptoms were associated with more negative updating of generalised performance beliefs.

Conclusions

There was cautious support for negatively biased belief updating associated with depressive symptoms, especially for generalised beliefs. The content of the task may not be self-relevant enough to cause strong biases. Further explication of Bayesian models of depression and replication in clinical samples is needed.

抑郁症状背景下信念更新的贝叶斯模型检验

目的研究抑郁症信念更新的预测加工方法，提出抑郁症与更负性和更精确的先验相关。此外，与规范贝叶斯更新相比，信念更新被认为是负偏的。目前尚无有效的方法对抑郁症患者的信念更新进行数学建模。方法:我们在非临床样本(N = 133)中验证了一种新的绩效信念更新范式。参与者反复参与非自我相关的情绪识别任务，并得到错误的反馈。采用贝叶斯多水平分析分析反馈操作和抑郁症状差异对信念更新的影响。结果通过反馈，成功地操纵了信念。与规范贝叶斯更新相比，抑郁症状与负性更新的相关程度更高，但结果受少数病例的影响。没有证据表明有偏见的信念改变或过于精确的先验。抑郁症状与更消极地更新一般表现信念有关。结论消极偏见信念更新与抑郁症状相关，尤其是广义信念更新。任务的内容可能没有足够的自我相关性，从而导致强烈的偏见。需要进一步解释贝叶斯抑郁症模型并在临床样本中复制。

期刊介绍： The International Journal of Methods in Psychiatric Research (MPR) publishes high-standard original research of a technical, methodological, experimental and clinical nature, contributing to the theory, methodology, practice and evaluation of mental and behavioural disorders. The journal targets in particular detailed methodological and design papers from major national and international multicentre studies. There is a close working relationship with the US National Institute of Mental Health, the World Health Organisation (WHO) Diagnostic Instruments Committees, as well as several other European and international organisations. MPR aims to publish rapidly articles of highest methodological quality in such areas as epidemiology, biostatistics, generics, psychopharmacology, psychology and the neurosciences. Articles informing about innovative and critical methodological, statistical and clinical issues, including nosology, can be submitted as regular papers and brief reports. Reviews are only occasionally accepted. MPR seeks to monitor, discuss, influence and improve the standards of mental health and behavioral neuroscience research by providing a platform for rapid publication of outstanding contributions. As a quarterly journal MPR is a major source of information and ideas and is an important medium for students, clinicians and researchers in psychiatry, clinical psychology, epidemiology and the allied disciplines in the mental health field.
