Conditions

Sarcoidosis, Fatigue

Brief summary

Fatigue is a pervasive and disabling symptom in sarcoidosis with limited treatment options. There is a significant association between heightened stress and sarcoidosis-associated fatigue. The proposed project will evaluate the usability/feasibility of a smartphone-based stress management application for the self-management of sarcoidosis-associated stress and fatigue.

Interventions

BEHAVIORALSarcoidosis Patient Assessment and Resource Companion App

The first group, called the SPARC group will be asked to download the SPARC app onto the participant's smartphone, will be shown how to use the app, and then will be asked to use the app to do guided meditations for ten minutes twice a day

Participants will receive education about reducing fatigue associated with sarcoidosis during a normal clinic visit.

Number of Participants Who Complete the Study6 monthsParticipants complete the study in it's entirety and are able to use the app appropriately
Number of Participants Who Maintain Adherence to at Least Daily Daily Breathing Awareness Meditation Sessions3 monthsAdherence is defined by participants completing 70% of the breathing awareness meditation sessions
Treatment SatisfactionMonth 3System Usability Scale (SUS) consists of ten statements each with five possible answers ranging from complete rejection to complete agreement. For each statement, the participant gives his or her approval or rejection in the form of a scale ranging from 1=strong approval to 5=strong rejection. The results of the SUS questionnaire are used to calculate a numerical value (SUS score). The results can have a value between 0 (worst application imaginable) and 100 (best application imaginable)

Secondary

MeasureTime frameDescription
Change in Sarcoidosis Associated Fatigue From Baseline to Month 6Week 0 and Week 24SAF is measured by Fatigue Assessment Scale which is a Fatigue Questionnaire (1 to 5-point scale x 10 questions for a total score range of 0 to 50) where a low value indicates less fatigued (better outcome) and a high value indicates more fatigued (worse outcome)
Changes in Quality of LifeWeek 0 and Week 24Quality of life is measured by the King's Sarcoidosis Health Questionnaire (KSQ), which is a 29 item scale that asks the participant questions about their general health, lung health, medications, skin, and eyes. Reliability = .90 -.97. A positive change represents an improvement (increase) in QOL. range 0-100; positive number = improvement
Changes in Self-Efficacy From Baseline to Month 3Week 0 and Week 12Self-Efficacy is measured by the Fatigue Self-Efficacy Sale which is an 8 item scale to assess how the participant handles fatigue. Scores range from 0 to 100, with higher scores representing better fatigue self-efficacy.
Changes in Stress From Baseline to Month 6Week 0 and Week 24Stress is measured by the Perceived Stress Scale which is a 10 item scale that asks about feelings and thoughts during the last month. The scale ranges from 0-40, lower score meaning low stress, and a higher score meaning high stress. A negative change represents an improvement (decrease) in stress
Changes in Autonomous MotivationWeek 0 and Week 24Autonomous motivation is measured by the Treatment Self-Regulation Questionnaire (TSRQ), which is a 15 item scale that assesses the degree of autonomous self-regulation to explain why participants engage or would engage in healthy behavior. The higher the score, the better the outcome.
