What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relative Abundance of Commensal Microorganisms

    Counts of microbes per gram of each organism on GI-MAP test

    Measured: Baseline and end of 8-week intervention

Secondary outcomes (5)
  1. Functional and Microbial Markers of Intestinal Health

    Functional and microbial markers of intestinal health on the GI-MAP will be categorized as low, medium, and high

    Measured: Baseline and end of 8-week intervention

  2. Gastrointestinal Symptoms Rating Scale

    Validated questionnaire assessing gastrointestinal symptoms. Total scores across all domains range from 15-105. Higher scores indicate worse gastrointestinal symptoms.

    Measured: Baseline and end of 8-week intervention

  3. Digestion-Associated Quality of Life Questionnaire

    Validated questionnaire assessing the impact of digestion on quality of life. Total scores across all domains range from 0 to 81. Higher scores indicate worse digestion-associated quality of life.

    Measured: Assessed at baseline and end of 8-week study.

  4. PROMIS - Global Health

    Validated questionnaire assessing global physical and mental health. T scores range from 16.2 to 67.7 for physical health and from 21.2 to 67.6 for mental health. Higher scores indicate better physical and mental health.

    Measured: Baseline and end of 8-week study.

  5. PROMIS - Anxiety Short Form 8a

    Validated questionnaire assessing feelings of anxiety. T scores range from 37.1 to 83.1. Higher scores indicate greater feelings of anxiety.

    Measured: Assessed at baseline and end of 8-week study.
