The "Shih-Hsu Test of Attention" (SHTA) is an iPad-based attention assessment tool developed in recent years by occupational therapists and has acceptable criterion-related validity and high test-retest reliability in preliminary application. This research project explores the criterion-related validity and test-retest reliability of SHTA between people with and without schizophrenia.
The participants were 76 adults with schizophrenia aged 20-64 years, and 66 adults without diagnosed mental illness aged 20-64 years were recruited in this study on a voluntary basis. Each participant was assessed twice. The participants completed both the SHTA and Chu's Attention Test (CAT) in the first test and the SHTA after 3 weeks.
Analytical results indicate that the SHTA has satisfactory test-retest reliability (ICC = 0.67) and criterion-related validity (γ = 0.29, < 0.05*) for adults with schizophrenia and has high test-retest reliability (ICC = 0.90) and criterion-related validity (γ = 0.25, < 0.05*) for adults without diagnosed mental illness. The MDC% value for the subjects without diagnosed mental illness was 12.1%, indicating acceptable random measurement error.
Our preliminary findings show that the iPad-based attention assessment tool, SHTA, has satisfactory criterion-related validity and test-retest reliability, supporting the future application of SHTA as an attention assessment tool.
“施旭注意力测试”（SHTA）是职业治疗师近年来开发的一种基于iPad的注意力评估工具，在初步应用中具有可接受的效标关联效度和较高的重测信度。本研究项目探讨了SHTA在精神分裂症患者和非精神分裂症患者之间的效标关联效度和重测信度。
本研究自愿招募了76名年龄在20至64岁之间的成年精神分裂症患者，以及66名年龄在20至64岁之间未被诊断患有精神疾病的成年人。每位参与者接受两次评估。在第一次测试中，参与者同时完成SHTA和朱式注意力测试（CAT），并在3周后再次完成SHTA。
分析结果表明，SHTA对成年精神分裂症患者具有令人满意的重测信度（ICC = 0.67）和效标关联效度（γ = 0.29，P < 0.05*），对未被诊断患有精神疾病的成年人具有较高的重测信度（ICC = 0.90）和效标关联效度（γ = 0.25，P < 0.05*）。未被诊断患有精神疾病的受试者的MDC%值为12.1%，表明随机测量误差可接受。
我们的初步研究结果表明，基于iPad的注意力评估工具SHTA具有令人满意的效标关联效度和重测信度，支持SHTA作为一种注意力评估工具在未来的应用。
