To develop and examine the psychometric properties of a scale to specifically assess satisfaction with methadone in heroin-dependent patients.
The 44-item preliminary version of the scale to assess satisfaction with medications for addiction treatment-methadone for heroin addiction (SASMAT-METHER) was obtained from a pool of items designed to assess satisfaction with any medication-addiction combination. Theoretical domains of the initial SASMAT-METHER were overall satisfaction, pharmacotherapy, initiation, anti-addictive effect on heroin, mental state, physical state, personal functioning, acceptability, and anti-addictive effect on secondary substances. The Treatment Satisfaction Questionnaire for Medication 1.4 version (TSQM 1.4) and the Verona Service Satisfaction Scale for Methadone Treatment (VSSS-MT) were used for concurrent validation. Participants included heroin-dependent patients receiving methadone treatment for at least the last 3 months.
The preliminary version of the SASMAT-METHER scale was completed by 241 patients, with 180 surveys considered suitable for factor analysis. Principal component analysis of these SASMAT-METHER surveys revealed a 3-factor structure that accounted for 40.4% of total variance. Based on similarities between empirically-obtained factors and theoretical domains, factors 1 through 3 were named 'Personal Functioning and Well-Being' (7 items), 'Anti-Addictive Effect on Heroin' (5 items), and 'Anti-Addictive Effect on Other Substances' (5 items). All factors showed good to excellent internal consistency (Cronbach's α: 0.83-0.92) and test-retest reliability (intraclass correlation coefficients: 0.66-0.89). Correlations between overall SASMAT-METHER and TSQM 1.4 scores were stronger (Pearson r=0.69) than correlations between overall SASMAT-METHER and VSSS-MT scores (Pearson r=0.26).
These results present evidence for the validity and reliability of SASMAT-METHER.
开发并检验一种专门用于评估海洛因依赖患者美沙酮满意度的量表的心理测量特性。
从旨在评估对任何药物成瘾组合的满意度的项目库中获取了44个项目的评估成瘾治疗药物——海洛因成瘾用美沙酮满意度量表（SASMAT - METHER）的初步版本。初始SASMAT - METHER的理论领域包括总体满意度、药物治疗、起始、对海洛因的抗成瘾作用、精神状态、身体状态、个人功能、可接受性以及对次要物质的抗成瘾作用。使用药物治疗满意度问卷1.4版（TSQM 1.4）和维罗纳美沙酮治疗服务满意度量表（VSSS - MT）进行同时效度验证。参与者包括至少在过去3个月接受美沙酮治疗的海洛因依赖患者。
241名患者完成了SASMAT - METHER量表的初步版本，其中180份调查问卷被认为适合进行因子分析。对这些SASMAT - METHER调查问卷进行主成分分析，揭示了一个三因素结构，占总方差的40.4%。根据实证获得的因素与理论领域之间的相似性，因素1至3分别命名为“个人功能与幸福感”（7个项目）、“对海洛因的抗成瘾作用”（5个项目）和“对其他物质的抗成瘾作用”（5个项目）。所有因素均显示出良好至优秀的内部一致性（克朗巴哈α系数：0.83 - 0.92）和重测信度（组内相关系数：0.66 - 0.89）。总体SASMAT - METHER与TSQM 1.4得分之间的相关性（皮尔逊r = 0.69）强于总体SASMAT - METHER与VSSS - MT得分之间的相关性（皮尔逊r = 0.26）。
这些结果为SASMAT - METHER的有效性和可靠性提供了证据。
