Study Details

Study Description

Brief Summary

65% of the general population reported experiencing moderate to severe bloating symptoms. Bloating could be disturbing to patients and frustrating to the physicians as an effective treatment is still lacking. Guided Imagery (GI) involves the structured visualisation of mental images with somatic sensory; whereas Progressive Muscle Relaxation (PMR) focuses on tightening and relaxing the body's specific muscle groups. The development and validation of GI or PMR interventions to treat patients with functional abdominal bloating are relatively novel.

Detailed Description

The baseline variables of the patient would be obtained at the outpatient Gastrointestinal Medical clinic. A thorough general clinical interview that encompasses medical and psychological history, discussion of the nature and severity of the current symptoms, and review of past treatments and conclusions of any medical evaluation and tests. This is to make sure that the patients have been comprehensively evaluated medically and to rule out other causes of abdominal bloating before reaching a firm diagnosis of functional abdominal bloating as suggested in ROME IV Criteria. Questionnaires will be given out and patients were asked to fill it up on the spot. Electrical activity and abdominal circumference would be measured at an enclosed space with appropriate privacy and accompanied by a chaperone.

Imagery Therapy

The intervention group will undergo imagery therapy while the control group will undergo the progressive muscle relaxation therapy which acts as a the control for this study. Participants from both groups will receive identical instructions and thorough explanations with visual aids regarding their respective interventions. Both groups will undergo the therapy for 12 sessions respectively in an alternate day basis. Both groups will be required to listen to a pre-recorded mp3 recording, either a progressive muscle relaxation therapy or an imagery therapy script. They will need to follow the instructions given in the recordings in each session on their own at least once a day, particularly after a meal. They are required to record the time they carried out their intervention in a logbook that was provided. A demonstration and face-to-face guidance will be given to the patients on the initial baseline assessment as well.

Progressive Muscle Relaxation Therapy

Progressive muscle relaxation (PMR) therapy works by progressively relaxing and tensing the muscle groups throughout the entire body. The PMR script used in this study was validated and used by previous researchers. Each muscle group will be tensed for about 5 seconds. If there's any pain or discomfort at any of the targeted areas, participants were told to omit that particular step. Constant purposeful deep breathing was instructed throughout the session especially in between changes of muscle. Participants were seated in a comfortable position and in a cool and quiet environment. Throughout the intervention, participants may visualize the muscles tensing followed by a wave of relaxation as they release the tension slowly. A momentary pause about 5-10 seconds will be given to the participant, allowing them to relax before moving on from one muscle group to another.

Control Group

A typical psychological intervention may call upon a wait-list control to provide researcher a clear cut comparison in terms of efficacy between the groups. However, from an ethical point of view in medicine, a wait-list control group may attribute to negative emotional and psychosocial effects. Furthermore, the existence of such group may hinder the blinding process and induces bias in the study. Therefore, there is a need to determine and select a suitable placebo control intervention.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Guided Imagery (GI)

A 8 minute audio that focuses on evoking mental images in reducing the abdominal bloating sensation in patients

Behavioral: Guided Imagery
Individualized Guided Imagery (GI) technique, an alternative type of relaxation therapy. The content of GI usually includes scenery, places or any image projected to the mind. By using information generated, participants are guided to create a place in their mind using their senses of touch, sound, smell, sight and taste.
Other Names:
  • Imagery (Psychotherapy)
  • Imagery, Guided
  • Psychotherapy Imagery
  • Imagery Psychotherapy
  • Active Comparator: Progressive Muscle Relaxation (PMR)

    A 8 minute audio that focuses on contracting certain muscle groups and relaxing it progressively in reducing the abdominal bloating sensation in patients

    Behavioral: Progressive Muscle Relaxation
    Progressive muscle relaxation (PMR) therapy works by progressively relaxing and tensing the muscle groups throughout the entire body. Each muscle group will be tensed for about 5 seconds. If there's any pain or discomfort at any of the targeted areas, participants were told to omit that particular step. Constant purposeful deep breathing was instructed throughout the session especially in between changes of muscle.
    Other Names:
  • Progressive Relaxation
  • Placebo Comparator: Audiobook

    A 8 minute audio that focuses on providing educational information regarding functional gastrointestinal disorders and related knowledge.

    Other: Educational Audiobook
    Participants in the control group will receive an audiobook that targets to educate patients regarding gut-brain disorders, functional gastrointestinal disorders, causes of functional abdominal bloating, and treatment modalities available. Relaxing musical background will be added to facilitate the delivery.

    Outcome Measures

    Primary Outcome Measures

    1. Symptoms severity [1 month]

      Measured using the Malay version of Bloating Severity Questionnaire (BSQ-M). It consists of two components: five-item Sev24 and seven-item SevGen. The responses were in a multiple-choice answer format on different degrees of effect towards individuals on the basis of intensity, frequency and severity (less severe to more severe; range 1 to 4,5,6,7 or 8 varied by items). Higher scores in BSQ indicate worse severity.

    Secondary Outcome Measures

    1. Health belief [1 month]

      Measured using the Malay-Language Health of Bloating (HB-Bloat) Scale. The questionnaire consists of 12 items and 3 domains: attitude (3 items), subjective norm (5 items), perceived control towards self-management (4 items). All responses were measured on a five-point Likert scale from 1 (strongly disagree) to 5 (strongly agree).

    2. Health seeking Intention [1 month]

      Measured using Health Seeking Intention for Abdominal Bloating Scale. It is a 5 point Likert scale that consists of 1 domain and 1 item. 1 indicates "strongly diagree" while 5 indicates "strongly agree"

    3. Health promoting behavior [1 month]

      Measured using Health Promoting Behavior Scale of Abdominal Bloating. The questionnaire consists of 4 domains and 15 items. The questionnaire is a 5 point Likert scales, whereby 1 is considered strongly disagree and 5 is considered strongly agree.

    4. Anxiety [1 month]

      Measured using the Malay version of Hospital Anxiety and Depression Scale (HADS). It comprises of 14 items, seven of which is related to anxiety symptoms. Each item is coded from 0 to 3. The scores for anxiety and depression can therefore vary from 0 to 21, depending on the presence and severity of the symptoms. A score between 0 and 7 does not indicate the presence of the symptoms of anxiety; a score between 8 and 10 indicates the presence of a moderate symptom; a score of 11 and above indicates a significant number of symptoms of anxiety corresponding to confirmed cases.

    5. Depression [1 month]

      Measured using the Malay version of Hospital Anxiety and Depression Scale (HADS). It comprises of 14 items, seven of which is related to anxiety symptoms. Each item is coded from 0 to 3. The scores for anxiety and depression can therefore vary from 0 to 21, depending on the presence and severity of the symptoms. A score between 0 and 7 does not indicate the presence of the symptoms of anxiety; a score between 8 and 10 indicates the presence of a moderate symptom; a score of 11 and above indicates a significant number of symptoms of anxiety corresponding to confirmed cases.

    6. Abdominal circumference [1 month]

      Using a non-stretch metric tape

    7. Electrical activity [1 month]

      Measured using the Megawin ME6000 Electromyograph

    8. Quality of life for patients with abdominal bloating [1 month]

      Measured using the Malay version of Bloating Quality of Life (BLQoL-M) Questionnaires. The responses for BLQoL were in a 7-point Likert scale on different degrees of impact towards individual ranging from 1 = "never/not related to me" to 7 = "always". Higher scores in BLQoL indicate higher impact towards QoL.
