Earworms are a form of involuntary musical imagery which are in many ways similar to musical hallucinations and obsessions present in clinical disorders, such as schizophrenia and obsessive-compulsive disorder (OCD). Previous research has shown relationships between earworms and schizotypy as well as subclinical OCD. The aim of this study was to investigate these associations in a Hungarian sample of 4301 participants. We hypothesized that (1) there would be significant correlations between aspects of schizotypy, subclinical OCD and earworms; (2) higher scores on either the Obsessive-Compulsive Inventory – Revised (OCI-R) or the Schizotypal Personality Questionnaire – Brief Revised (SPQ-BR) would be associated with more negative attitudes toward earworm experiences, as measured with the Negative valence factor of the Involuntary Musical Imagery Scale (IMIS), as well as (3) longer and more frequent earworm episodes. Bayesian Kendall’s tau-b correlations showed weak relationships between several aspects of both schizotypy and subclinical OCD, and introspection related to earworms and earworm-related movement. S tructural equation models showed that subclinical OCD had a weak, positive association with negative attitudes toward earworms, while schizotypy had a positive association with earworm frequency, earworm-related movement, and earworm-related introspection. These results partially support previous findings, and provide new, relevant information about the associations of personality traits and earworms in a large sample.

心中的旋律：耳虫、分裂型和亚临床强迫症之间的关联


耳虫是一种不自主的音乐意象，在许多方面类似于精神分裂症和强迫症 （OCD） 等临床疾病中存在的音乐幻觉和强迫症。先前的研究表明，耳虫与分裂型以及亚临床强迫症之间存在关系。本研究的目的是在 4301 名参与者的匈牙利样本中调查这些关联。我们假设 （1） 分裂型、亚临床强迫症和耳虫的各个方面之间存在显着相关性;（2） 强迫症量表 - 修订版 （OCI-R） 或分裂型人格问卷 - 简要修订版 （SPQ-BR） 的较高分数将与对耳虫经历的更消极态度相关，如非自愿音乐意象量表 （IMIS） 的负效价因子所衡量，以及 （3） 更长、更频繁的耳虫发作。贝叶斯 Kendall 的 tau-b 相关性显示分裂型和亚临床 OCD 的几个方面之间关系较弱，内省与耳虫和耳虫相关运动相关。S 结构方程模型显示，亚临床 OCD 与对耳虫的消极态度呈微弱的正相关，而分裂型与耳虫频率、耳虫相关运动和耳虫相关内省呈正相关。这些结果部分支持以前的发现，并提供了有关大样本中人格特征和耳虫关联的新的相关信息。
