The present study was conducted with the aim of designing a causal model for the evaluation of sexual dysfunctions based on the variables of methadone dosage and sexual self-concept among individuals undergoing methadone maintenance treatment (MMT).
The study population of the present study consisted of married men of 20 to 45 years of age with sexual ýrelations and undergoing MMT for a minimum of 8 weeks referring to all MMT clinics of Kerman, Iran, in ýý2015-2016. ýThe subjects were selected through multi-stage cluster sampling (n = 250). Data were collected using the General Health Questionnaire (GHQ-28), Multi-Dimensional Sexual Self-concept Questionnaire (MSSQ), and Internal Index for Erectile Function (IIEF). Data were analyzed using path analysis method and Pearson correlation coefficient. The suggested model was evaluated using structural equation model (SEM), and indirect relationships were assessed using Bootstrap method.
The suggested model showed acceptable fitness with the data, and all routes, except methadone use route, to sexual function were significant. The result of the multiple ýindirect route showed that sexual function had a significant relationship with methadone use through ýsexual self-concept. In total, 60% of variance in sexual dysfunction was explained using the variables of the suggested model.
Further studies are suggested to be conducted regarding psychological factors effective on the sexual dysfunctions among individuals undergoing MMT, such as sexual self-concept. Moreover, more detailed evaluation of each subscale of positive and negative sexual self-concept is recommended to assess the psychological causes of sexual dysfunctions in these individuals and design psychological, behavioral, and cognitive-behavioral treatment interventions for them.
本研究旨在基于美沙酮维持治疗（MMT）个体的美沙酮剂量和性自我概念变量，设计一个用于评估性功能障碍的因果模型。
本研究的研究人群包括20至45岁有性生活且正在接受MMT至少8周的已婚男性，他们于2015 - 2016年前往伊朗克尔曼的所有MMT诊所就诊。通过多阶段整群抽样选取研究对象（n = 250）。使用一般健康问卷（GHQ - 28）、多维性自我概念问卷（MSSQ）和勃起功能内部指数（IIEF）收集数据。采用路径分析方法和Pearson相关系数对数据进行分析。使用结构方程模型（SEM）评估所提出的模型，并使用Bootstrap方法评估间接关系。
所提出的模型与数据显示出可接受的拟合度，除美沙酮使用路径外，所有通向性功能的路径均具有显著性。多条间接路径的结果表明，性功能通过性自我概念与美沙酮使用存在显著关系。所提出模型的变量总共解释了性功能障碍60%的方差。
建议针对影响MMT个体性功能障碍的心理因素，如性自我概念，开展进一步研究。此外，建议对积极和消极性自我概念的每个子量表进行更详细的评估，以评估这些个体性功能障碍的心理原因，并为他们设计心理、行为和认知行为治疗干预措施。
