Nerva Patient Survey: Analysis of Self-Reported Satisfaction Post Completion of 6-Week Gut-Directed Hypnotherapy Program

‍The first question, regarding the overall satisfaction with Nerva stated, “how would you rate your overall satisfaction with Nerva?” There were 2,065 respondents, and the scale was 1-5 stars. The average response was 4.2/5 stars. 42.5% responded with 5 stars, 39.9% responded with 4 stars, 14.2% responded with 3 stars, 2.4% responded with 2 stars, and 1% responded with 1 star. [Figure 1]

The second question stated, “how would you feel if you could no longer use Nerva?” There were 2,119 respondents, and the responses were, “somewhat disappointed,” “very disappointed,” and “not disappointed.” 48.9% responded they would be “somewhat disappointed” if they could no longer use the Nerva program. 36.7% responded they would be “very disappointed” if they could no longer use the Nerva program. And 14.4% responded they would “not [be] disappointed” if they could no longer use the Nerva program. [Figure 2]

The third question stated, “how likely are you to recommend Nerva to someone with IBS?” There were 2,119 respondents, and the scale was 0 (not likely at all) to 10 (very likely). The average response was 8.4/10. 45.4% responded 10, 13.2% responded 9, 15.1% responded 8, 10.9% responded 7, and the following 15.3% responded if the 0-6 range. [Figure 3]

The final question stated, “have you seen any reduction in symptoms so far?” There were 1,369 respondents, and the responses were, “yes!” and “not yet.” 81.4% responded they have seen symptom improvement. 18.6% responded they have not yet seen symptom improvement. [Figure 4]

Discussion:

The self-reported satisfaction with the Nerva program is generally positive. Sentiment in a digital therapeutic is an integral component of the program because it fosters adherence and therefore symptom improvement. Continual qualitative and quantitative studies monitoring sentiment are required to maintain the efficacy of the Nerva program.
