The perpetration of harmful sexual behavior is a global concern, with deviant sexual fantasies identified as a prominent etiological risk factor. However, the concepts of state sexual fantasy characteristics (e.g., vividness and emotionality) and associated trait sexual memory intensity have received minimal investigation concerning harmful sexual interests, formulating the impetus for this research. Two online surveys were conducted in community populations. Study 1 (N = 414) aimed to validate the psychometric properties of a trait sexual memory intensity scale (SMIS) through principal components analysis, confirmatory factor analysis, and evaluation of concurrent validity. Study 2 (N = 820) endeavored to explore associations between state sexual fantasy characteristics and cognitive-behavior variables (e.g., frequency of masturbation to a reported fantasy), and evaluate differences in fantasy characteristics and SMIS scores between participants with and without harmful sexual interests. Collectively, results supported the factor structure, concurrent validity, and internal consistency of the SMIS, while revealing significant associations between the SMIS, sexual fantasy characteristics, and several variables. Significant differences in sexual fantasy characteristics and SMIS scores were evident but variable among harmful sexual interests. Findings encourage the consideration and research of interventions focused on impairing mental imagery and memory in the management of harmful sexual interests.

有害性行为的实施是一个全球性的问题，不正常的性幻想被认为是一个突出的病因风险因素。然而，状态性幻想特征（例如，生动性和情感性）和相关特征性记忆强度的概念很少受到有关有害性兴趣的调查，这为这项研究奠定了动力。对社区人群进行了两项在线调查。研究 1（N  = 414）旨在通过主成分分析、验证性因素分析和并行有效性评估来验证性状记忆强度量表 (SMIS) 的心理测量特性。研究 2（N = 820）致力于探索状态性幻想特征和认知行为变量（例如，对报告的幻想进行手淫的频率）之间的关联，并评估有和没有有害性兴趣的参与者之间幻想特征和 SMIS 分数的差异。总的来说，结果支持 SMIS 的因素结构、并行有效性和内部一致性，同时揭示了 SMIS、性幻想特征和几个变量之间的显着关联。性幻想特征和 SMIS 评分存在显着差异，但有害性兴趣之间存在差异。研究结果鼓励考虑和研究以损害心理意象和记忆为重点的干预措施，以管理有害的性兴趣。
