Probiotic Administration on Mood (PAM)

20 de abril de 2022 actualizado por: Lindenwood University

Impact of Probiotic Administration on Mood, Psychological Traits, Physical Activity, Stress, and Sleep Quality

Researchers are looking to examine the impact of probiotic administration on symptoms commonly associated with depression, anxiety, stress, sleep quality, and associated emotional responses in healthy men and women.

Descripción general del estudio

Descripción detallada

In recent years, the presence and awareness of a connection between the intestines and the brain has expanded leading to the understanding of developed communication pathways between the nervous, endocrine, and immune systems. Intestinal bacterial flora are active contributors to this axis through cellular signaling pathways and the release of immune system components, which fundamentally impact the function and action of various physiological systems. Interest in this area evolved through the understanding that various microbiota can produce neuroactive substances and neurotransmitters involved with the endocrine and autonomic nervous system pathways. This research has expanded to state that various bacterial products can influence cognitive functions, involving types of memory and problem-solving. Recent findings have begun to report on the impact that probiotic administration may have on mood, anxiety, and depression. Finally, recent work by Marotta et al. provided some of the first preliminary evidence that probiotic use may also impact mood and sleep quality. While initial work has developed this foundation, very little controlled research is available to help understand key contributing factors. For example, many key questions remain that future research should address to help better understand any impact probiotics may have on mood, depression, and anxiety. Some of these questions include:

Do all forms (genus, strain, etc.) of probiotics exert these impacts? How quickly do they exert impact? How large is the impact? Are certain aspect of affect more impacted than others? Once supplemented, how long is the residual impact (if there is any)? To help provided more guidance towards some of these basic research questions, this study is being proposed. The purpose of the study is to expand upon the previous work of Marotta et al. and determine the impact of probiotic administration on mood, depressive symptoms, anxiety, sleep quality, and other personality traits in a larger group of healthy men and women. This study will expand on the supplementation regimen and include a wider variety of hormonal assessments than what has previously been completed using this combination of probiotics.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: Active Probiotic
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).
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.
Comparador de placebos: Placebo
Maltodextrin capsule
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.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Beck Depression Index II
Periodo de tiempo: 6 Weeks

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
Periodo de tiempo: 6 weeks
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
Periodo de tiempo: 6 weeks
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
Periodo de tiempo: 6 weeks

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
Periodo de tiempo: 6 weeks
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
Periodo de tiempo: 6 weeks
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
Periodo de tiempo: 6 weeks
Measure of bowel health. Lower scores indicate lower number of GI disturbances and higher scores indicate higher number of GI disturbances
