Summary
Direct text messages were most effective for improving adherence to at-home saliva cortisol collection. This study highlights how reminder techniques can enhance participant compliance in behavioral and health research.
Area of Science:
- Behavioral Science
- Health Science
- Psychology
Background:
- Saliva cortisol collection is a noninvasive method for monitoring stress hormones.
- Multiple samples over days are beneficial for behavioral and health studies.
- Various self-collection methods exist, including passive drool.
Purpose of the Study:
- To investigate reminder techniques for improving adherence to passive drool cortisol collection.
- To assess adherence in African American and European American young adults.
- To compare the effectiveness of different reminder strategies.
Main Methods:
- Participants collected 4 saliva samples daily for 3 days using passive drool.
- Various reminder techniques were employed to encourage adherence.
- Adherence rates were analyzed based on reminder type and participant demographics.
Main Results:
- Direct text message reminders were associated with the highest adherence rates.
- Phone reminders were most effective when controlling for total contact frequency.
- Both traditional and novel reminder methods positively influenced adherence.
Conclusions:
- Effective reminder strategies are crucial for successful at-home sample collection.
- Tailored reminder approaches can improve adherence in diverse populations.
- Findings support the use of varied reminder techniques in stress hormone research.

Transportation of samples from the collection point to the laboratory, as well as storage and preservation techniques, are crucial for maintaining sample integrity and ensuring accurate and reliable test results.
Samples should be transported carefully from collection points to the laboratory. They should be properly sealed and clearly labeled to prevent cross-contamination. To preserve the sample integrity, optimal temperature conditions during transport are essential. This could involve using...
