NASA PVT+ 1.4.4

The official NASA PVT+ (Psychomotor Vigilance Test) is a validated iOS-based touchscreen application created for research purposes. It incorporates various industry-standard forms for gathering extensive research data related to sleep, alertness, and performance studies.

• The Simple PVT: This feature allows for a single presentation of the Psychomotor Vigilance Test (PVT) with no limit on the number of attempts.
• Basic Study: Offers a structured framework, spanning single or multiple days, facilitating the collection of research data through designated prompts for a sleep diary, PVT assessments, and Karolinska Sleepiness Scale (KSS) responses.
• Aviation Study: Tailored specifically for aviation-related research, this feature encompasses Off-Duty Days and Duty Days sections, guiding participants through specific tasks including sleep diaries, PVT assessments, KSS responses, and more.

The key components within the NASA PVT+ application are:

• Psychomotor Vigilance Test (PVT): A reaction-timed test aimed at detecting effects of sleep deprivation and circadian disruptions. The test requires participants to tap the screen at the appearance of a millisecond counter within a box.
• Karolinska Sleepiness Scale (KSS): A self-reported scale for rating sleepiness levels over specific time intervals.
• Sleep Diary: Includes pre- and post-sleep episode entries detailing sleep patterns and quality assessment.
• Study Enrollment Information: Consists of relevant questionnaires and practice exercises to acclimate participants to study procedures.

Data collected using the NASA PVT+ iOS application does not contain Personally Identifiable Information (PII). Research data is only transmitted to NASA with explicit agreements between external organizations and NASA.
