Additionally, it aims to develop a machine learning model to predict the presence of insomnia in participants using response time data.  \nMethods: A mobile application was designed to administer scale tests and collect response time data from 2729 participants. The relationship between symptom severity and response time was explored, and a machine learning model was developed to predict the presence of insomnia.  \nResults: The result revealed a statistically significant difference (p\u003C.001) in the total response time between participants with or without insomnia symptoms. A correlation was observed between the severity of specific insomnia aspects and response times at the individual questions level. The machine learning model demonstrated a high predictive accuracy of 0.743 in predicting insomnia symptoms based on response time data.  \nConclusions: These findings highlight the potential utility of response time data to evaluate cognitive and psychological measures, demonstrating the effectiveness of using response time as a diagnostic tool in the assessment of insomnia.  \nKeywords: response time; machine learning; insomnia; behavioral data.  \nIntroduction  \nPsychological self-assessment scales are widely used to evaluate various mental health factors, including insomnia. However, these scales often come with the subjective bias of the participants, leading to potential inconsistencies in severity and symptom expression 1,2. Especially for self-assessment scales, the reports of people on their own thoughts, feelings, and behaviors often result in subjective bias 3. For instance, the Insomnia Severity Index (ISI) scale, employed in this study, may yield divergent assessments of insomnia severity and symptoms even when two individuals report identical scores. With the advent of information technology, participants can conveniently answer assessment scales on their personal device 4. At the same time, their behavioral data during the answering process can also be collected 5. This behavioral data can offer an objective perspective on the participant's state during the scale completion, and could significantly assist in the interpretation of scale results 6.  \nResponse Time (RT), which represents the duration taken by a participant to respond to a stimulus or complete a task, is a meaningful metric commonly used in various experiments in cognitive psychology 7. In cognitive psychology research, RT functions as a dependent variable, influenced by manipu","cbCainrpMvlCI9Jz","https://ap.wps.com/l/cbCainrpMvlCI9Jz","pdf",1362073,1,27,"English","en",105,"# Introduction\n# Objectives\n# Methods\n# Results\n# Conclusions","[{\"question\":\"What is the main goal of the study?\",\"answer\":\"The study investigates the relationship between insomnia and response time sequence, and develops a machine learning model to predict insomnia presence from response-time data.\"},{\"question\":\"How was response time data collected?\",\"answer\":\"A mobile application administered scale tests and collected response time data from 2,729 participants during the answering process.\"},{\"question\":\"What did the results show about response time?\",\"answer\":\"Participants with insomnia symptoms had a statistically significant difference in total response time, and severity of specific insomnia aspects correlated with response times at the individual question level.\"},{\"question\":\"How accurate was the machine learning model?\",\"answer\":\"The model achieved a predictive accuracy of 0.743 for identifying insomnia symptoms using response time data.\"}]","Exploring the relationship between response time sequence in scale answering process and severity of insomnia -
