NCT04560595

Brief Summary

The purpose of this online research study is to determine whether or not a gradual caffeine reduction program developed at Johns Hopkins can help people reduce their caffeine use. The investigators will provide materials to help guide caffeine reduction and ask questions to track caffeine use over several weeks. The investigators will also assess how reducing caffeine may benefit common caffeine-related problems such as anxiety, sleep disturbances, and gastrointestinal distress. The study will also determine whether or not people like participating in this caffeine reduction program in an online format.

Outcome Measures

Primary Outcomes (2)

  • Number of Participants With Treatment Retention as Assessed by Number of Participants With Completed Assessments

    To determine to what extent participants will engage with a remote caffeine reduction intervention for caffeine-related problems and find it acceptable, we will calculate the percentage of completed assessments for each video visit among eligible participants.

    Treatment Visit, 7-Week Follow-Up, 14-Week Follow-Up

  • Treatment Acceptability as Assessed by Treatment Acceptability Questionnaire

    At the 7 Weeks Follow-Up video visit, we will use an internally-developed standardized treatment acceptability questionnaire to determine self-reported agreement with two items on the treatment acceptability survey (i.e., "Overall, was the Guide to Caffeine Reduction and Cessation easy to use?", and "Overall, was the guide to Caffeine reduction and Cessation helpful?"). Each question is scored on a scale from 0-3, for a total score range of 0-6, where lower scores indicate less acceptability (e.g., 0=not at all easy, not at all helpful; 3 = very easy, very helpful).

    7 weeks Follow-Up visit

Secondary Outcomes (9)

  • Change in Caffeine Consumption (in Milligrams)

    Baseline, Treatment Visit, 7-Week Follow-Up, 14-Week Follow-Up

  • Change in Caffeine-related Problems as Assessed by Past-7 Days Standardized Items

    Baseline, 7-Week Follow-Up, 14-Week Follow-Up

  • Change in Anxiety as Assessed by the PROMIS-Anxiety-8a

    Baseline, 7-Week Follow-Up, 14-Week Follow-Up

  • Change in Anxiety as Assessed by the GAD-7

    Baseline, 7-Week Follow-Up, 14-Week Follow-Up

  • Change in Sleep Problems as Assessed by the PROMIS Sleep Disturbance 8a

    Baseline, 7-Week Follow-Up, 14-Week Follow-Up

  • +4 more secondary outcomes

Study Arms (2)

Caffeine Reduction Manual, Immediate Treatment Group

EXPERIMENTAL

Weekly caffeine consumption is to be measured before and after using the caffeine reduction program, which has been summarized in a "Guide to Caffeine Reduction and Cessation" manual to help people reduce their caffeine use. Those in the immediate treatment group will receive the guide immediately after screening.

Behavioral: Caffeine Reduction Manual

Caffeine Reduction Manual, Delayed Treatment Group

EXPERIMENTAL

Weekly caffeine consumption is to be measured before and after using the caffeine reduction program, which has been summarized in a "Guide to Caffeine Reduction and Cessation" manual to help people reduce their caffeine use. Those in the delayed treatment group will receive the guide seven weeks after screening.

Behavioral: Caffeine Reduction Manual

Interventions

We will provide participants with a Guide to Caffeine Reduction and Cessation in order to help the reduce their caffeine use and determine their ratings of treatment acceptability.
