坚持同一性（IS）包括一系列行为模式，包括对变化的抵抗，常规和仪式化行为，这些行为可以在社会和非社会环境中存在。考虑到IS所包含的行为的广度，重要的是要确定这个领域是最好的概念化和测量作为一个一维或多维的结构。因此，目前的研究旨在描述IS的结构，并探索已确定的IS因素与相关因素（包括年龄、性别、智商、焦虑、社交能力、情绪和行为失调以及感觉超敏反应）之间潜在的不同关联模式。探索性图形分析使用限制和重复行为的维度评估来检查样本1892名自闭症青少年（法师= 10.82，SDage = 4.14;范围：3-18岁; 420名女性）的IS结构，该样本来自西蒙斯基金会为知识提供动力的自闭症研究队列。确定了三个不同的IS子域，分别标记为IS-仪式/相同，IS-行为和IS-其他（指与他人互动期间的IS行为）。广义加法模型表明，每个IS子域显示出独特的模式与关键变量的关联。更具体地说，虽然感觉超敏反应与IS-仪式主义/相同和IS-行为密切相关，但与IS-其他无关。此外，虽然情绪失调是IS-仪式主义/相同性的独特预测因子（但不是IS-仪式主义或IS-他人），但社会互动能力是IS-仪式主义/相同性或IS-他人的独特预测因子。目前的研究结果提供了初步证据，IS可能包括几个不同的子域。
Insistence on sameness (IS) encompasses a range of behavioral patterns, including resistance to change, routines, and ritualized behaviors, that can be present across social and non‐social contexts. Given the breadth of behaviors encompassed by IS, it is important to determine whether this domain is best conceptualized and measured as uni‐ or a multi‐dimensional construct. Therefore, the current study aimed to characterize the structure of IS and explore potentially distinct of patterns of associations between identified IS factors and relevant correlates, including age, sex, IQ, anxiety, social abilities, emotional and behavioral dysregulation, and sensory hypersensitivity. Exploratory graph analysis was conducted using the dimensional assessment of restricted and repetitive behaviors to examine the structure of IS in a sample 1892 autistic youth (Mage= 10.82,SDage= 4.14; range: 3–18 years; 420 females) recruited from the Simons Foundation Powering Autism Research for Knowledge cohort. Three distinct IS subdomains labeled as IS‐Ritualistic/sameness, IS‐Routines, and IS‐Others (referring to IS behaviors during interactions with others) were identified. Generalized additive models demonstrated that each of the IS subdomains showed a unique pattern of association with key variables. More specifically, while sensory hypersensitivity was significantly associated with IS‐Ritualistic/sameness and IS‐Routines, it was not associated with IS‐Others. Further, while emotional dysregulation was a unique predictor of IS‐Ritualistic/sameness (but not IS‐Routines or IS‐Others), social interaction abilities were a unique predictor of IS‐Routines (but not IS‐Ritualistic/sameness or IS‐Others). Current findings provide preliminary evidence that the IS may encompass several distinct subdomains.
