Abstract

Introduction

Apathy is a negative symptom of schizophrenia and is associated with poor real world functioning. Therefore, it is important to have validated psychometric instruments to assess this symptom. This is the first study to validate the Spanish adaptation of the self-rated version of the Apathy Assessment Scale (AES-S) in patients with schizophrenia.

Materials and methods

Naturalistic, cross-sectional, validation study in 104 patients with schizophrenia evaluated using the following scales: Clinical Global Impression-Severity (CGI-S), Personal and Social Performance (PSP), Clinical Assessment Interview for Negative Symptoms (CAINS), Self-report of Negative Symptoms (SNS), Motivation and Pleasure Scale-Self-Report (MAP-SR), Calgary Depression Scale for Schizophrenia (CDSS), and Apathy Evaluation Scale-self-rated version (AES-S).

Results

Reliability: Internal consistency (Cronbach's alpha) was 0.908. Convergent validity: The Pearson correlation coefficient between AES-S and CAINS-MAP total scores was −0.483 (p < 0.001). For SNS, total and avolition subscale scores were −0.803 and −0.639 (p < 0.001), respectively. With the MAP-SR, the correlation coefficient was −0.727 (p < 0.001). Divergent validity: The Pearson correlation coefficient between AES-S and PSP total scores was 0.504 (p < 0.001). Furthermore, with the CDSS, the correlation coefficient was −0.431 (p < 0.001). Discriminant validity: The AES-S discriminated between different levels of illness severity according to CGI-S scores. Factor analysis: A three-component solution explained 57.32% of the variance. Pearson correlations between coefficients were 1–2 = 0.265, 1–3 = 0.464, and 2–3 = 0.060.

Conclusion

The Spanish AES-S is a reliable and valid instrument for assessing apathy in Spanish patients with schizophrenia. It seems to be appropriate for use in everyday clinical practice as a means of monitoring apathy in these patients.

精神分裂症患者冷漠评估量表自评版(AES-S)的欧洲西班牙改编的验证

冷漠是精神分裂症的一种阴性症状，与现实生活功能低下有关。因此，重要的是要有有效的心理测量工具来评估这种症状。这是第一个验证西班牙语自评版冷漠评估量表(AES-S)在精神分裂症患者中的适应性的研究。材料与方法对104例精神分裂症患者进行自然、横断面、验证性研究，采用以下量表进行评估:临床总体印象-严重程度(ci -s)、个人与社会表现(PSP)、阴性症状临床评估访谈(CAINS)、阴性症状自述(SNS)、动机与愉悦量表-自述(MAP-SR)、精神分裂症卡尔加里抑郁量表(CDSS)和冷漠评估量表-自评版(AES-S)。结果信度:内部一致性(Cronbach’s alpha)为0.908。收敛效度:AES-S总分与CAINS-MAP总分的Pearson相关系数为- 0.483 (p <0.001)。SNS的总分和自愿分分别为- 0.803分和- 0.639分(p <分别为0.001)。MAP-SR的相关系数为- 0.727 (p <0.001)。发散效度:AES-S与PSP总分的Pearson相关系数为0.504 (p <0.001)。此外，与CDSS相关系数为- 0.431 (p <0.001)。区分效度:AES-S根据CGI-S评分区分不同程度的疾病严重程度。因子分析:三组分解决方案解释了57.32%的方差。系数间Pearson相关性为1-2 = 0.265,1-3 = 0.464,2-3 = 0.060。结论西班牙AES-S量表是一种可靠、有效的评估西班牙精神分裂症患者冷漠程度的工具。它似乎适合在日常临床实践中使用，作为监测这些患者冷漠的手段。
