Satisfaction with antipsychotic medication is an important outcome variable. To date, there is a lack of a well-established measure to quantify patient satisfaction with psychiatric medication. This paper describes the development, dimensionality, reliability and validity of the Satisfaction with Antipsychotic Medication (SWAM) scale.
Clinical and academic experts devised a 33-item Likert scale satisfaction questionnaire. Following a pilot study in a sample of 69 people with schizophrenia, 315 people with schizophrenia on the caseload of local mental health services in three London boroughs completed the questionnaire. The dimensionality, internal consistency and validity of the devised instrument were assessed.
Reliability of the SWAM scale was good for subscales and total scores. The alpha coefficient for the two subscales: treatment acceptability and medication insight were 0.92 and 0.84 respectively. The a coefficient for the SWAM scale total score was 0.91 and ranged from 0.92 to 0.90.
Testing of the psychometric properties of the SWAM scale demonstrate that it is a reliable instrument for measuring patient satisfaction with antipsychotic medication. The measure could be used in routine clinical practice in mental health services to assess patient satisfaction with psychiatric medication.
对抗精神病药物的满意度是一个重要的结果变量。迄今为止，缺乏一种成熟的方法来量化患者对抗精神病药物的满意度。本文描述了抗精神病药物满意度（SWAM）量表的开发、维度、信度和效度。
临床和学术专家设计了一份包含33个条目的李克特量表满意度问卷。在对69名精神分裂症患者进行预试验后，伦敦三个行政区当地心理健康服务机构登记在册的315名精神分裂症患者完成了该问卷。对所设计工具的维度、内部一致性和效度进行了评估。
SWAM量表各分量表和总分的信度良好。两个分量表（治疗可接受性和药物认知）的α系数分别为0.92和0.84。SWAM量表总分的α系数为0.91，范围在0.92至0.90之间。
对SWAM量表心理测量特性的测试表明，它是一种测量患者对抗精神病药物满意度的可靠工具。该测量方法可用于心理健康服务的常规临床实践，以评估患者对抗精神病药物的满意度。
