  Purpose

The purpose of this study is 1) to determine whether a comprehensive self-management intervention is effective in a sample that includes men and women with irritable bowel syndrome, and 2) to determine whether the comprehensive self-management intervention is as effective when delivered over the telephone as compared to a face-to-face approach.

Primary Outcome Measures:
  • Gastrointestinal symptoms [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]
  • Psychological distress [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]
  • Cognitive Scale for Functional Bowel Disorders (CFBD) describes 25 cognitive beliefs related to functional bowel disorders. [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]
  • Health Related Quality Of Life (HRQOL) will be measures with the Disease Specific Questionnaire-IBS (IBS-DSQ), a 42-item questionnaire. [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]

  • Sexual dysfunction [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]
  • Catecholamine and cortisol levels (urine) [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]
  • Stool frequency/consistency [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]
  • Health care utilization [ Time Frame: baseline, and 3 months, 6 months, 12 months post randomization ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: 1
Face-to-Face Individualized Comprehensive Self-Management (CSM-FF) Group. Participants in the individualized CSM-FF group will be scheduled for 9 weekly sessions with the nurse therapist followed by post-intervention follow-up assessment.
 Behavioral: cognitive-behavioral
Cognitive-behavioral over 9 weeks
Other Names:
  • Cognitive-behavioral
  • Usual care
Experimental: 2
Telephone Individualized Comprehensive Self-Management (CSM-TEL) Group. Participants in the individualized CSM-FTF group will initially have 2 face-to-face meetings with the nurse therapist, 6 sessions over the phone and the final session face-to-face at 9 weeks.
 Behavioral: cognitive-behavioral
Cognitive-behavioral over 9 weeks
Other Names:
  • Cognitive-behavioral
  • Usual care
No Intervention: 3
Usual Care Control Group (UC). Following randomization the participants in the control group will receive two short phone calls to maintain contact during the comparable 9-week intervention in the treatment groups.
 Behavioral: cognitive-behavioral
Cognitive-behavioral over 9 weeks
Other Names:
  • Cognitive-behavioral
  • Usual care

Detailed Description:

Randomization and Intervention Phase. Upon completing the baseline assessment phase, participants will be randomized to one of 3 treatment groups. A customized computer program will be used to do the randomization in an adaptive manner that ensures the 3 groups remain fairly balanced with respect to possible important predictors of outcomes: age, sex, predominant stool pattern (alternating, constipation-predominant or diarrhea-predominant), and severity of IBS symptoms and psychological symptoms at baseline. When each new participant is randomized, the program will adjust the probabilities of assignment to the three groups so that there is a higher probability of assignment to the group that results in the best balance.

Intervention Groups. Face-to-Face Individualized Comprehensive Self-Management (CSM-FF) Group. Participants in the individualized CSM-FF group will be scheduled for 9 weekly sessions with the nurse therapist followed by post-intervention follow-up assessment.

Telephone Individualized Comprehensive Self-Management (CSM-TEL) Group. Participants in the individualized CSM-TEL group will initially have 2 face-to-face meetings with the nurse therapist, 6 sessions over the phone and the final session face-to-face at 9 weeks.

Usual Care Control Group (UC). Following randomization the participants in the control group will no receive any contacts during the comparable 9-week intervention in the treatment groups.

Follow-up Phase. Participants in all 3 groups will be reassessed at 3-mo, 6-mo, and 12-mo post randomization. At this time the participants will complete questionnaires, a 4 week diary and collect 4 urines.
