Trial Outcomes & Findings for Cognitive Behavioral Therapy and Real-Time Pain Management Intervention for Sickle Cell Via Mobile Applications (NCT NCT04419168)

NCT ID: NCT04419168

Last Updated: 2025-02-19

Results Overview

The 8-item Patient Reported Outcomes Measure Information System Pain Interference (PROMIS-8a) assesses the effect of patient-reported pain on relevant aspects of a person's life and may include the extent to which pain hinders engagement with social, cognitive, emotional, physical, and recreational activities in the past 7 days. The items use 1-5 Likert scale with higher scores indicating greater pain interference. The raw total score (ranging from 8 to 40) is transformed using a T-score for a mean of 50, standard deviation of 10, in referent population. Higher T-scores indicate greater pain.

cCBT
Computerized cognitive behavioral therapy (cCBT) for pain. The cCBT program will teach users how to recognize negative thoughts and emotions, use cognitive skills and problem-solving, and apply coping behaviors such as distraction, activity scheduling, and relaxation. The cCBT arm emphasizes skills acquisition and learning through practice; this intervention is consistent with the tailored behavioral services patients would receive individually or as a group when working with a psychologist or behavioral pain specialist. cCBT: A digital, internet-delivered, evidence-based chatbot programmed to deliver content for both cCBT.
m-Education
Mobile-delivered pain and sickle cell disease education (m-Education). The m-Education program will teach users about chronic pain, healthy lifestyle tips (e.g., nutrition and exercise), and facts about SCD. This program is consistent with the education patients and families would receive with a patient educator. m-Education: A digital, internet-delivered, evidence-based chatbot programmed to deliver content for both m-Education.

The ASCQ-ME emotional functioning and social impact quality-of-life measure was specifically designed for SCD and evaluates the health care experience of patients with SCD, emotional response to stress, and social relationships. For each subscale (emotional impact in the past 7 days and social functioning impact in the past 30 days), there are 5 questions using a 1-5 Likert scale with lower scores indicating worse health. Raw total scores (ranging from 5 to 25) are transformed using a T-score for a mean of 50, standard deviation of 10, in referent population. Lower T-scores indicate worse health.

The Sickle Cell Disease Self-Efficacy Scale is a nine-item self-administered questionnaire that measures disease-specific perceptions of the ability to manage day-to-day issues resulting from sickle cell disease (SCD). Items are scores according to a five-point scale ranging from "1 - Not sure at all" to "5 - Very sure." Responses from individual items are summed to give an overall score with higher scores indicating greater self-efficacy (ranging from 9 to 45).

Painimation is an electronic pain assessment tool that allows users to better communicate pain symptoms. Patients are provided with a selection of animations (painimations) that they use to describe the quality of their pain. The painimations can be adjusted to reflect pain intensity. Screenshots of the Painimation app illustrate the splash screen, paintable body image, and selection of painimations to indicate the quality and intensity of pain. A higher mean % is indicative of greater pain. For analyses, mean percentages are transformed via arc-sine square in order to normalize.

The Sickle Cell Disease Self-Efficacy Scale is a nine-item self-administered questionnaire that measures disease-specific perceptions of the ability to manage day-to-day issues resulting from sickle cell disease (SCD). Items are scores according to a five-point scale ranging from "1 - Not sure at all" to "5 - Very sure." Responses from individual items are summed to give an overall score with higher scores indicating greater self-efficacy (ranging from 9 to 45).

Painimation is an electronic pain assessment tool that allows users to better communicate pain symptoms. Patients are provided with a selection of animations (painimations) that they use to describe the quality of their pain. The painimations can be adjusted to reflect pain intensity. Screenshots of the Painimation app illustrate the splash screen, paintable body image, and selection of painimations to indicate the quality and intensity of pain. A higher mean % is indicative of greater pain. For analyses, mean percentages are transformed via arc-sine square in order to normalize.
