From: Enhancing response time thresholds with response behaviors for detecting disengaged examinees

ItemThreshold size (in seconds)Reason
CD item 140The proportion of behaviors to provide a response started to increase
CD item 210Proportion of the “no action” group sharply declined
CD item 320The proportion of behaviors to provide a response started to increase
Star item 120Proportion of the “no action” group sharply declined
More examinees started to perform various type of available behaviors
Star item 220The proportion of behaviors to provide a response became almost similar between disengaged and engaged
Star item 320Proportion of the “no action” group sharply declined
The proportion of behaviors to provide a response started to increase
Star item 420Proportion of the “no action” group sharply declined
The proportion of behaviors to provide a response started to increase
  1. One or more instances in the guidelines can be observed for an item. When two consecutive thresholds indicated similar results, we chose the smaller threshold
