Several studies indicate that subjective experience toward antipsychotic drugs (APs) in schizophrenic patients is a key factor in ensuring a smooth recovery from the illness.
The principal aim of this study was to establish the psychometric performance of the Subjective Well-being Under Neuroleptic (SWN) scale in its Italian version and to assess, through the SWN scale, the subjective experience of stabilized psychotic outpatients in maintenance with APs.
The original short version of SWN, consisting of 20 items, was back translated, and a focus group was also conducted to better improve the comprehension of the scale.
The results showed a good performance of the Italian version of the SWN as documented by the internal consistency (Cronbach's alpha; 0.85). A satisfactory subjective experience was reported in the sample of schizophrenic outpatients interviewed (SWN mean total score: 84.95, SD: 17.5).
The performance of the SWN scale in the present study was very similar to that reported by Naber et al. in the original validation study. Large multi-center studies are needed to better establish differences in the subjective experience of schizophrenic patients treated with first- and second-generation APs.
多项研究表明，精神分裂症患者对抗精神病药物（APs）的主观体验是确保病情顺利康复的关键因素。
本研究的主要目的是确定意大利语版抗精神病药所致主观幸福感（SWN）量表的心理测量性能，并通过SWN量表评估接受APs维持治疗的病情稳定的精神病门诊患者的主观体验。
对由20个项目组成的原始简短版SWN进行回译，并开展焦点小组讨论以更好地提高对该量表的理解。
结果显示，意大利语版SWN表现良好，内部一致性（克朗巴哈系数；0.85）证明了这一点。在接受访谈的精神分裂症门诊患者样本中，报告了令人满意的主观体验（SWN平均总分：84.95，标准差：17.5）。
本研究中SWN量表的表现与纳伯等人在原始验证研究中报告的非常相似。需要开展大型多中心研究，以更好地确定接受第一代和第二代APs治疗的精神分裂症患者主观体验的差异。
