Protocol - Distress Tolerance
The Computerized Mirror Tracing Persistence Task (MTPT-C) is an automated version of the original Mirror Tracing Persistence Task (Quinn et al., 1996), which requires the construction of a mirror box and multiple copies of polygons to be traced. The MTPT-C simplifies the administration and scoring of this task.
In this task, participants are required to trace a red dot along the lines of a geometric shape (e.g., star) using the computer’s mouse. However, the mouse moves the red dot in the reverse direction. Each time the participant moves the mouse out of the lines or hesitates for more than 2 seconds, a buzzer sounds, and the dot moves back to the beginning. Three progressively more difficult shapes are used. The first two rounds last 1 minute each, while the third round of the MTPT-C can last up to 7 minutes. Participants may terminate the task at any point during the third round by pressing on the space bar. Distress tolerance is measured by the latency in seconds to task termination. Additionally, the number of errors per second (i.e., number of times the participant has to return to the starting position during the task, divided by the task time) is recorded to control for effects of skill on persistence.

The ability to persist in a goal-directed activity when experiencing psychological distress or ability to tolerate psychological distress in general. One measurement approach is time spent on a frustrating behavioral task (i.e., task persistence). Distress tolerance appears to be a relatively stable trait. Across measures, it has been found to be predictive of substance-use outcomes, including smoking cessation. Individuals who are low in distress tolerance may have greater difficulty in maintaining tobacco abstinence in the face of withdrawal and other challenges.
The Mirror Tracing Persistence Task (MTPT) has discriminated between smokers and nonsmokers and has predicted smoking cessation outcomes. The original MTPT required the construction or purchase of a physical box with a slanted mirror one side. The participant inserts his or her hand and traces geometric figures while only watching the hand in the mirror. This is extremely difficult and frustrating. Persistence is scored as the mean time on several trials prior to giving up. The Computerized MTPT (MTPT-C) was developed to make the test more accessible, as it did not require the physical equipment. It has potential as a screening instrument to identify individuals at high risk of initiating smoking or of smoking cessation failure. To date, the MTPT-C has predicted treatment dropout among substance abusers, but it has not been tested with smokers per se.
