Abstract
Objectives
This systematic review aims to explore the comorbidity of schizotypy and schizotypal personality disorder (SPD) with eating disorders (EDs).
Methods
Four databases (Cochrane Library, PubMed, PsycINFO and Web of Science) were searched for empirical studies published through 2023. Eligible studies underwent data extraction, risk of bias assessment and subsequent analyses.
Results
A total of 11 studies with 2236 patients were included in the present review. The three main types of EDs—anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED)—along with their subtypes were involved. Patients with AN and both anorexia and bulimia nervosa exhibited more obvious schizotypal manifestations, whereas those with BN showed less severe schizotypal levels.
Conclusions
EDs are closely linked with schizotypy and SPD. Schizotypal manifestations vary across different types of EDs. The cognitive and social deficits highlighted by schizotypy and SPD and their associated neurobiological dysfunction may be related to abnormal and pathological eating behaviours. Future research should further investigate their comorbid relationships, especially potential transdiagnostic indicators.
目的探讨分裂型及分裂型人格障碍(SPD)与饮食障碍(EDs)的合并症。方法检索Cochrane Library、PubMed、PsycINFO和Web of Science 4个数据库,检索截至2023年发表的实证研究。对符合条件的研究进行数据提取、偏倚风险评估和后续分析。结果本综述共纳入11项研究,2236例患者。eds的三种主要类型:神经性厌食症(AN)、神经性贪食症(BN)和暴食症(BED)及其亚型。AN合并神经性厌食症和神经性贪食症患者的分裂型表现更为明显,而BN患者的分裂型表现较轻。结论ed与精神分裂型和SPD密切相关。分裂型表现因不同类型的ed而异。精神分裂型和SPD突出的认知和社会缺陷及其相关的神经生物学功能障碍可能与异常和病理性饮食行为有关。未来的研究应进一步探讨它们的合并症关系,特别是潜在的跨诊断指标。
期刊介绍:
Clinical Psychology & Psychotherapy aims to keep clinical psychologists and psychotherapists up to date with new developments in their fields. The Journal will provide an integrative impetus both between theory and practice and between different orientations within clinical psychology and psychotherapy. Clinical Psychology & Psychotherapy will be a forum in which practitioners can present their wealth of expertise and innovations in order to make these available to a wider audience. Equally, the Journal will contain reports from researchers who want to address a larger clinical audience with clinically relevant issues and clinically valid research.
