What is being measured

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

  1. To evaluate the effect of Bifidobacterium Longum (BL NCC3001) on Gastrointestinal Symptoms

    Change from baseline to week 6 in Irritable Bowel Severity Scoring System (IBS-SSS), a questionnaire that includes 5 questions related to the severity of abdominal pain, frequency of abdominal pain, severity of abdominal distention, dissatisfaction with bowel habits, and interference with quality of life over the past 10 days. This cumulative score can therefore range from 0 to 500, with higher scores indicating more severe symptoms.

    Measured: Baseline to 6 weeks.

  2. To evaluate the effect of Bifidobacterium Longum (BL NCC3001) on Psychological Symptoms

    Change from baseline to week 6 in Hospital Anxiety and Depression Scale (HADS-Total) score, a 14-item scale assessing two dimensions (anxiety and depression, 7 items for each) of psychological distress. Each item is scored from 0-3 in a Likert manner. Outcome measures are the anxiety score (0-21), depression score (0-21) and the total score (0-42).

    Measured: Baseline to 6 weeks.

Secondary outcomes (18)
  1. Hospital Anxiety Depression Scale - Depression (HADS-D) score

    Change from baseline to Week 6 in Hospital Anxiety Depression Scale-Depression (HADS-D) score, a 14-item scale assessing depression (7 items) of psychological distress. Each item is scored from 0-3 in a Likert manner. Outcome measures are the depression score (0-21).

    Measured: Day -1, Day 43 (± 2 days)

  2. Hospital Anxiety Depression Scale - Anxiety (HADS-A) score

    Change from baseline to Week 6 in Hospital Anxiety Depression Scale-Anxiety (HADS-A) score, a 14-item scale assessing anxiety (7 items) of psychological distress. Each item is scored from 0-3 in a Likert manner. Outcome measures are the anxiety score (0-21).

    Measured: Day -1, Day 43 (± 2 days)

  3. Depression Anxiety Stress Scale (DASS-21)

    Change from baseline to Week 6 in Depression Anxiety Stress Scale (DASS-21), a four-point Likert scale ranging from 0 ("did not apply to me at all") to 3 ("applied to me very much" or "most of the time"). The outcome measures correspond to the total scores (0-21) of the subscales.

    Measured: Day -1, Day 43 (± 2 days)

  4. Perceived Stress Scale (PSS)

    Change from baseline to Week 6 in Perceived Stress Scale (PSS), includes several direct queries about current levels of experienced stress, each item is rated on a Likert scale (0-4), the range of the total score is 0-40.

    Measured: Day -1, Day 43 (± 2 days)

  5. Irritable Bowel Severity Scoring System (IBS-SSS) Pain severity

    Change from baseline to Week 6 in Irritable Bowel Severity Scoring System (IBS-SSS) pain severity, a question related to the severity of abdominal pain over the past 10 days. The question is scored on a 100-point visual analogue scale, which is anchored with the 2 extremes (e.g., no pain on the far left to severe pain on the far right).

    Measured: Day -1, Day 43 (± 2 days)

  6. Irritable Bowel Severity Scoring System (IBS-SSS) Pain frequency

    Change from baseline to Week 6 in Irritable Bowel Severity Scoring System (IBS-SSS) pain frequency, a question related to the frequency of abdominal pain over the past 10 days. The question is scored on a 100-point visual analogue scale, which is anchored with the 2 extremes (e.g., no pain on the far left to severe pain on the far right).

    Measured: Day -1, Day 43 (± 2 days)

  7. Irritable Bowel Severity Scoring System (IBS-SSS) Bloating severity

    Change from baseline to Week 6 in Irritable Bowel Severity Scoring System (IBS-SSS) bloating severity, a question related to the severity of abdominal distention over the past 10 days. The question is scored on a 100-point visual analogue scale, which is anchored with the 2 extremes (e.g., no pain on the far left to severe pain on the far right).

    Measured: Day -1, Day 43 (± 2 days)

  8. Irritable Bowel Severity Scoring System (IBS-SSS) Bowel habit

    Change from baseline to Week 6 in Irritable Bowel Severity Scoring System (IBS-SSS) bowel habit, a question related to dissatisfaction with bowel habits over the past 10 days. The question is scored on a 100-point visual analogue scale, which is anchored with the 2 extremes (e.g., no pain on the far left to severe pain on the far right).

    Measured: Day -1, Day 43 (± 2 days)

  9. Irritable Bowel Severity Scoring System (IBS-SSS) Life impact

    Change from baseline to Week 6 in Irritable Bowel Severity Scoring System (IBS-SSS) life impact, a question related to interference with quality of life over the past 10 days. The question is scored on a 100-point visual analogue scale, which is anchored with the 2 extremes (e.g., no pain on the far left to severe pain on the far right).

    Measured: Day -1, Day 43 (± 2 days)

  10. Irritable Bowel Syndrome Quality of Life questionnaire (IBS-QoL)

    Change from baseline to Week 6 in Irritable Bowel Syndrome Quality of Life questionnaire (IBS-QoL), a 34-item, validated, condition-specific measure based on 5-point Likert scale for assessing health-related quality of life in the past month among persons with IBS.

    Measured: Day -1, Day 43 (± 2 days)

  11. Patient Health Questionnaire (PHQ-12)

    Change from baseline to Week 6 in Patient Health Questionnaire (PHQ-12), each somatic symptom is evaluated in a Likert scale from 0 to 2 (not bothered at all, bothered a little and bothered a lot) giving a maximum total of 24 points.

    Measured: Day -1, Day 43 (± 2 days)

  12. Sheehan Disability Scale (SDS)

    Change from baseline to Week 6 in Sheehan Disability Scale (SDS), the patients rates the extent to which work/school, social and family life are impaired by his/her symptoms on a 10-point VAS.

    Measured: Day -1, Day 43 (± 2 days)

  13. Amount of Bifidobacterium Longum (BL NCC3001) present in stool

    Change from baseline to Week 6

    Measured: Day -1, Day 43 (± 2 days)

  14. Irritable Bowel Severity Scoring System (IBS-SSS) score

    Change from baseline to Week 10 in Irritable Bowel Severity Scoring System (IBS-SSS) score, a cumulative score which can therefore range from 0 to 500, with higher scores indicating more severe symptoms. Mild, moderate, and severe cases are indicated by scores of 75 to 175.

    Measured: Day -1, Day 71 (± 2 days)

  15. Hospital Anxiety Depression Scale (HADS) total score

    Change from baseline to Week 10 in Hospital Anxiety Depression Scale (HADS) total score, a 14-item scale assessing two dimensions (anxiety and depression, 7 items for each) of psychological distress. Each item is scored from 0-3 in a Likert manner. Outcome measures are the anxiety score (0-21), depression score (0-21) and the total score (0-42).
