About this study

200 patients will be randomly divided into two groups - 100 patients will learn and practice COBMINDEX by a human therapist-social worker and 100 patients will learn and practice COBMINDEX by a digital therapist using the COBMINDEX application.

In the first 3-months there will be an assessment of patient progress following randomization to human therapist or digital therapist using the application for learning and practicing. During this period, the group of the human social-worker will have a limited access to the application dedicated for daily exercises and assessment.

In the following 9-month period, all patients will practice using the application, each group by it's permissions.

There will be daily assessment of stress, pain, fatigue, well-being and frequent assessments of patients' medical, psychological, and immunological status.

Throughout the trial, adverse events and concomitant medications will be collected.

In this arm the Patient learns techniques from a human therapist (the comperator for learning from the application) and practices using digital application.

Primary outcomes

  1. Effectiveness of application as compared to human therapist.

    Time frame: 12 months

    Develop a smartphone application that will teach the patient COBMINDEX and to determine whether the application will be as effective as the psychological intervention delivered by the therapists.

    the primary end point is SIBDQ disease specific HRQOL. 10 questions each scale 1-7 with range 7-70. higher is better.

Secondary outcomes

  1. Cost-effectiveness

    Time frame: 12 months

    To determine the cost-effectiveness of the intervention as provided by application versus therapists by prospective monitoring of direct and indirect healthcare costs. A cost-effectiveness analysis to assess the value for money of the application versus therapist interventions will be performed using primary data collected from patients in the study. These data include information of utilization of healthcare services reported by patients. The cost of each service will be based on the Israel Ministry of Health List Price for health services. We will calculate indirect costs of lost productivity based on patient responses to the WPAI questionnaire. For each patient we will calculate the quality-adjusted life-year (QALY) based on responses to the SF-12 questionnaires
