Clinical Trial Summary

The goal of this clinical trial is to learn about the impact of taking a continuous performance attention test on the physiological stress response in college students. The main questions it aims to answer are: - Does taking an attention test cause participants to have increases in heart rate, blood pressure, and sweat? - Does taking an attention test cause participants to have a decrease in heart rate variability? - Are there relationships between participants' levels of anxiety, perceived stress, and mindfulness to their physiological changes? Participants will - Answer questionnaires about anxiety, stress, and mindfulness - Have baseline measurements taken for blood pressure, sweat, and heart rate variability - Take the PEBL Continuous Performance Task (a 14 minute attention test) while having the measurements listed above taken again

Description:

The PEBL Continuous Performance Task is an example of a mental stressor which requires vigilance and effort. We hypothesize that a sympathetic nervous system response will be evident in comparing physiological parameters during the attention task versus the preceding resting baseline period. Exploratory analyses will assess relationships between psychological measures of anxiety, stress, and mindfulness with this physiological response and the number of errors on the attention test.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Blood pressure	Systolic and diastolic	Measured once after an 8 minute resting baseline, then 2 minutes into the attention task, and 10 minutes into the attention task. Data collection was then complete.
Primary	Skin conductance level	levels of sweat due to sympathetic nervous system activation	Measured continuously during an 8 minute resting baseline, then continuously for the 14 minute attention task. Data collection was then complete.
Primary	Heart rate variability	Normalized high frequency HRV	Measured continuously during an 8 minute resting baseline, then continuously for the 14 minute attention task. Data collection was then complete.
Secondary	State Trait Anxiety Inventory (STAI)	Spielberger, C.D., R.L. Gorsuch, and R.E. Lushene, 1970. Scores on each of the state and trait sections range from 20 (low anxiety) to 80 (high anxiety)	Questionnaire completed on day of enrollment (<30 minutes)
Secondary	Perceived Stress Scale (PSS-10)	Cohen, S., T. Kamarck, and R. Mermelstein. Journal of Health and Social Behavior, 1983. Scores range from 0 (low perceived stress) to 40 (high perceived stress)	Questionnaire completed on day of enrollment (<30 minutes)
Secondary	Mindful Awareness and Attention Scale (MAAS)	Brown, K.W. and R.M. Ryan. Journal of Personality and Social Psychology, 2003. Scores range from 1 (least mindful) to 6 (most mindful)	Questionnaire completed on day of enrollment (<30 minutes)
Secondary	PEBL Continuous Performance Task Foil Accuracy Rate	For trials where participants were presented with a foil, the percent in which the participant did not commit a commission error (participant correctly did not press spacebar). Ranges from 0 - 100% accuracy.	14 minute attention task on the day of the experiment
