摘要

许多精神分裂症谱系障碍(SSDs)患者都有严重的厌世情绪,这与预期性厌世情绪密切相关。然而,人们对预期性厌食症和非积极性的神经心理学基本原理知之甚少,因此对这些患者缺乏有效的治疗方法。积极心理想象的异常可能会干扰对快乐的预期,从而解释预期性失乐症和缺乏动机。然而,心理意象的性质及其与 SSD 患者非激励性精神病理学的关系在很大程度上还不为人所知。因此,在这项预先登记的研究中,我们考察了 SSD 患者的心理想象特征及其与预期性失乐症、非积极性和日常生活活动的关系。N = 86 名参与者包括 SSD 患者(n = 43)和人口统计学上相匹配的健康对照组(n = 43)。通过结构化访谈和自我报告问卷对心理想象、预期愉悦感、自卑感和活动参与度进行了评估。生态瞬间评估用于测量日常生活中的预期愉悦状态和活动参与度(81 人)。与对照组相比,SSD 组的心理想象数量相当,但生动程度较低。在横断面分析和前瞻性分析中,SSD 心理意象的生动性降低与预期性失乐症、缺乏积极性和活动参与度低有显著关联。心理意象的生动性降低可能会导致寻求愉悦体验的内在动力不足,这也是缺乏积极性的原因。旨在改善心理想象的生动性和相关的预期愉悦反应的干预措施可能会有效地解决缺乏动机的问题。

The Nature of Mental Imagery and Its Relationship With Amotivational Psychopathology in People With Schizophrenia Spectrum Disorders

Many people with schizophrenia spectrum disorders (SSDs) experience profound amotivation, which is strongly related to anticipatory anhedonia. Yet, the neuropsychological fundamentals of anticipatory anhedonia and amotivation are barely understood, resulting in a lack of effective treatments for these patients. Aberrancies in positive mental imagery may interfere with the anticipation of pleasure and could thus explain anticipatory anhedonia and amotivation. However, the nature of mental imagery and its relationship with amotivational psychopathology in SSD is largely unknown. In this preregistered study, we therefore examined mental imagery characteristics and their relation to anticipatory anhedonia, amotivation, and daily life activity in SSD. The N = 86 participants included individuals with SSD (n = 43) and demographically matched healthy controls (n = 43). Mental imagery, anticipatory pleasure, amotivation, and activity engagement were assessed with structured interviews and self-report questionnaires. Ecological momentary assessment was used to measure state anticipatory pleasure and activity engagement in daily life (n = 81). Compared to the control group, the SSD group showed comparable quantity, but less vividness of mental imagery. Reduced vividness of mental imagery in SSD was significantly associated with higher anticipatory anhedonia, amotivation, and low activity engagement in cross-sectional and prospective analyses. Reduced mental imagery vividness may cause a lack of internal incentive to seek pleasurable experiences and could explain amotivation. Interventions aiming to improve mental imagery vividness and related anticipatory pleasure responses in SSD may be effective in targeting amotivation.

期刊介绍: Behavior Therapy is a quarterly international journal devoted to the application of the behavioral and cognitive sciences to the conceptualization, assessment, and treatment of psychopathology and related clinical problems. It is intended for mental health professionals and students from all related disciplines who wish to remain current in these areas and provides a vehicle for scientist-practitioners and clinical scientists to report the results of their original empirical research. Although the major emphasis is placed upon empirical research, methodological and theoretical papers as well as evaluative reviews of the literature will also be published. Controlled single-case designs and clinical replication series are welcome.
