Second-by-Second Sensitivity Analysis of Response Time in Online Psychological Research

The uploaded file "Data5062all100percentComplete.xlsx" contains 5,062 rows (one per respondent) and 98 columns, consisting of complete responses retained after filtering the original cross-cultural EAI-3 survey to 100% completers. The columns include Qualtrics metadata (start/end timestamps, IP address, progress, total completion time in seconds, response ID, geolocation, user language), 18 sociodemographic items (SD1–SD16 plus Q27 and Q28), four COVID-related items (C19_1–C19_6_1), and the item-level responses for five validated psychometric scales: the Exercise Addiction Inventory-3 (EAIR_M_1–9), the Exercise Dependence Scale-Revised (EDSR_M_1–21), the SCOFF eating-disorder screen (SCOFF_M_1–5), the Obsessive-Compulsive Inventory-Revised (OCI_M_1–18), and the Ten-Item Personality Inventory (Q96_1–10). The final column, The "10secondby86Q", is a binary classification variable flagging respondents at the 10 s/item response-time cutoff (3,491 coded as fast, 1,571 as adequate).
