Outcome Measures

Primary Outcomes (7)

  • Beck Depression Index II

    The Beck Depression Inventory (BDI) is a 21-item, self-report rating inventory that measures characteristic attitudes and symptoms of depression. Total Score Levels of Depression 0-10 = These ups and downs are considered normal 11-16 = Mild mood disturbance 17-20 = Borderline clinical depression 21-30 = Moderate depression 31-40 = Severe depression over 40 = Extreme depression

    6 Weeks

  • COPE Inventory

    The COPE Inventory is a multidimensional coping inventory to assess the different ways in which people respond to stress. Five scales (of four items each) measure conceptually distinct aspects of problem-focused coping (active coping, planning, suppression of competing activities, restraint coping, seeking of instrumental social support); five scales measure aspects of what might be viewed as emotion-focused coping (seeking of emotional social support, positive reinterpretation, acceptance, denial, turning to religion); and three scales measuring coping responses that arguably are less useful (focus on and venting of emotions, behavioral disengagement, mental disengagement).

    6 weeks

  • Leiden Index of Depression Sensitivity - Revised

    The Leiden Index of Depression Sensitivity (LEIDS) measures cognitive reactivity (CR) to sadness, an aspect of cognitive vulnerability to depression, conceptually similar to rumination. A higher total score on all the subscales except acceptance and coping shows higher CR.

    6 weeks

  • Pittsburgh Sleep Quality Index

    A self-rated questionnaire to assess sleep quality and disturbances 19 self-reported items Minimum score: 0; Maximum score: 21 Higher scoring indicated worse sleep quality

    6 weeks

  • State-Trait Anxiety Inventory form Y1 and Y2

    Measure of trait and state anxiety. All items on the scale are rated on a 4-point scale (e.g., from "Almost Never" to "Almost Always"). Higher scores indicate greater anxiety. The STAI is appropriate for those who have at least a sixth-grade reading level.

    6 weeks

  • Behavioral Avoidance/Inhibition Scale

    A measure of motivation to approach goal-oriented outcomes. Higher scores correspond to higher motivation to avoid goal oriented outcomes, lower scores indicate lower motivation to avoid goal-oriented outcomes.

    6 weeks

  • Bowel Health Questionnaire

    Measure of bowel health. Lower scores indicate lower number of GI disturbances and higher scores indicate higher number of GI disturbances

Study Arms (2)

Active Probiotic

EXPERIMENTAL

A mixture of probiotic strains (2.5 gram daily doses of 4 x 109 CFU/packet) of the following species (Lactobacillus fermentum, Lactobacillus rhamnosus, Lactobacillus plantarum, Bifidobacterium longum).

Dietary Supplement: Probiotic

Placebo

PLACEBO COMPARATOR

Maltodextrin capsule

Dietary Supplement: Probiotic

Interventions

ProbioticDIETARY_SUPPLEMENT

After baseline or initial testing, participants will be randomly assigned in a double-blind fashion to ingest on a daily basis for 6 weeks either a placebo or a probiotic supplement. Identical follow-up measurements will then occur each visit after taking their assigned supplement. After 6 weeks of administration, the supplementation protocol will stop and a final evaluation will be completed 3 weeks later (9 weeks after initial administration) to assess any residual impact of the assigned supplement after a 3-week washout.
