Outcome Measures

Primary Outcomes (3)

  • Proportion of Intervention Sessions Completed by Participants

    Feasibility will be measured by the proportion of intervention sessions completed by participants. The intervention will be considered feasible if at least 50% of participants complete at least 6/9 sessions.

    Post-intervention at 9 weeks

  • Ease of Weekly Exercises

    Participants will provide ratings of ease after each weekly exercise, measured on a 10-point Likert scale (0=very difficult, 10=very easy).

    Weekly during intervention (weeks 1-8) and post-intervention (week 9)

  • Utility of Weekly Exercises

    Participants will provide ratings of utility after each weekly exercise, measured on a 10-point Likert scale (0=not at all helpful; 10=very helpful).

    Weekly during intervention (weeks 1-8) and post-intervention (week 9)

Secondary Outcomes (24)

  • Immediate Impact of the Exercises: Change in Optimism Ratings

    Weeks 1-9

  • Immediate Impact of the Exercises: Change in Happiness Ratings

    Weeks 1-9

  • Immediate Impact of the Exercises: Change in IBS Knowledge Ratings

    Weeks 1-9

  • Change in IBS Symptom Severity

    At baseline (week 1), at the mid-point of the intervention (week 5), post-intervention (week 9), and 3-months post-intervention (week 21)

  • Change in IBS Health-Related Quality of Life

    At baseline (week 1), at the mid-point of the intervention (week 5), post-intervention (week 9), and 3-months post-intervention (week 21)

  • +19 more secondary outcomes

Study Arms (2)

Positive Psychology (PP) Intervention

EXPERIMENTAL

Participants will complete an adapted, optimized, phone-based, 9-week positive psychology (PP) intervention.

Behavioral: Positive Psychology (PP) Intervention

Educational Intervention

ACTIVE COMPARATOR

Participants will complete a 9-week, phone-based educational intervention that matches the PP intervention in terms of both time and attention.

Behavioral: Educational Intervention

Interventions

This is an adapted, optimized, phone-based, 9-week positive psychology (PP) intervention. Participants will complete 9 weekly phone sessions (30 minutes each) with a study interventionist in which they will review PP exercises that they have independently completed in between phone sessions. The PP exercises will be completed in a treatment manual that describes the PP exercise and provides space to write about the exercise and its effects, and to answer associated questions. A total of 9 sessions will be completed over the course of the program.

Data Sharing

IPD Sharing
Will share

To help advance other research, de-identified data will be shared via respective repositories as specified below: * Clinical data including demographics, self-report questionnaires, and heart-rate variability will be shared via the Vivli repository. * Genomic data generated from RNA-seq will be submitted as FASTQ files to the Database of Genotypes and Phenotypes (dbGaP) which will then be shared to the Sequence Read Archive (SRA) with controlled access.

Shared Documents
STUDY PROTOCOL, SAP
Time Frame
Datasets will be provided to respective repositories by the end of the funding period. The clinical data shared with the Vivli repository will be archived and available for request by researchers for a minimum of 10 years after contribution. Genomic data will be preserved in the dbGaP/SRA repositories for at least three years following the completion of the grant.
Access Criteria
Clinical and genomic data will be shared with controlled access with the Vivli repository and dbGaP/SRA, respectively, for general research use, as allowed by the participants' informed consents and the Institutional Certification. Access to data requires the completion of a Data Use Agreement (DUA), which prohibits any redistribution or attempts to re-identify research participants.
