Pilot Evaluation of a Telehealth Motivational Interviewing Intervention Targeting Adherence Behaviors in Youth With Sickle Cell Disease

Sickle cell disease (SCD) is a group of inherited blood disorders affecting 100,000 individuals in the United States. SCD often leads to complications, including pain crises and organ damage. Many individuals with SCD require medications (e.g., Hydroxyurea or Endari) that research has demonstrated reduce risk of complications and improve quality of life. Despite the need for strong medication adherence, adolescents and young adults (AYAs; 13-25 years) have the lowest adherence rates compared to other age groups. Efforts to reduce AYA non-adherence risk should include youth in earlier childhood and persist throughout the AYA developmental period, with the goal of maintaining adherence throughout childhood and young adulthood. Motivational Interviewing (MI) has been effective in increasing pediatric and adult medication adherence via in-person or telehealth delivery; however, researchers have yet to empirically evaluate MI for feasibility, acceptability, and/or efficacy in improving pediatric/AYA SCD medication adherence. The proposed feasibility trial will provide preliminary feasibility data for a newly developed MI+education intervention targeting medication adherence for pediatric and adolescents and young adults (AYA) patients who have sickle cell disease. This trial will also evaluate study design feasibility to inform a future randomized controlled trial (RCT). The investigators are interested in delivering the intervention to AYA patients and to parents of younger children who have sickle cell disease because the investigators anticipate that establishing strong adherence in younger childhood could prevent future non-adherence during the AYA developmental period. Participants will include 13-22 year-old patients with sickle cell disease as well as parents of 0-22 year-old patients with sickle cell disease. The investigators will randomize ten families to a 4-session telehealth MI+education intervention and five families to a one-session education-only control condition. All participants will complete assessments at three times. Intervention participants will complete the T2 assessment at their last intervention session (week 4-8), and the T3 assessment 16-20 weeks after study enrollment. Education arm participants will complete T2 assessments 4-8 weeks after study enrollment and will complete T3 assessments 16-20 weeks after study enrollment. Primary outcomes include intervention feasibility and acceptability and study design feasibility.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Description

Inclusion Criteria:

  • Participants will include 13-22 year-old patients with sickle cell disease as well as primary caregivers of 0-22 year-old sickle cell disease patients ("parents"). The lower age limit for patients' participation in their own intervention sessions was selected based on previous studies documenting MI effectiveness with adolescents as young as 13 years of age. The upper limit was selected based on the recruitment site's (JHACH) patient population.
  • Participants must be able to speak and understand spoken English because MI is language-dependent.
  • The patient's SCD regimen must include at least one of the following medications: Hydroxyurea, Endari, Adakveo, or Oxbryta.
  • Patients who meet inclusion criteria may participate even if their parent chooses not to do so, although 13-17 year old patients may only participate with parent consent. Likewise, parents of patients may participate even if the AYA declines their own participation, as long as the AYA assents/consents to medical chart review. Adult patients (18-22 years of age) will not require parent consent and may choose to participate with or without a parent.

Exclusion Criteria:

  • Potential participants who appear to have cognitive, motor, or language delays, as observed by research personnel or documented in the medical record, will be excluded from this study if delays preclude informed consent and/or study completion. Participants may request that research personnel read all assessment, education, and intervention materials aloud in a structured interview format, in which case participants could respond to items verbally and/or by pointing to visual aids. Because of this option, participants' ability to read and write are not requirements for participation.
  • Because the MI component of the intervention is language-dependent and requires significant time and training for certification in another language, non-English speaking patients will only be included in this study if the psychology postdoctoral fellow hired in this study is a native Spanish speaker and can demonstrate MI proficiency in Spanish.
  • Participants who score in the clinically significant range (t-scores 2 standard deviations above the mean) on any of the PROMIS measures assessing depression and anxiety will be removed from the study and provided mental health resources.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in sickle cell disease medication adherence
Time Frame: Baseline, post intervention (weeks 4-8 after study enrollment), and 16-20 weeks after study enrollment
This questionnaire assesses participants' adherence to their sickle cell disease medication. The questionnaire is titled Sickle Cell Antibiotic Adherence Level Evaluation (SCAALE). Question items are scored in different directions depending on whether their wording reflects adherence or non-adherence. For each item, participants will rate each item on a Likert scale, such that the response indicating the 'best' adherence is scored one point and the response indicating the 'worst' adherence is scored five points. Possible subscale scores range from four points (most adherent) to 20 points (least adherent),and possible total scores range from 24 (most adherent) to 120 (least adherent).
Baseline, post intervention (weeks 4-8 after study enrollment), and 16-20 weeks after study enrollment
Intervention feasibility as assessed by the fidelity rating
Time Frame: Post intervention (weeks 4-8 after study enrollment)
Feasibility of conducting the intervention with high clinician fidelity, as evidenced by fidelity ratings for each session (fidelity represented as a percentage based on the extent to which the clinician covered all planned information for each session). Average intervention fidelity ratings should meet or exceed 80 percent fidelity.
Post intervention (weeks 4-8 after study enrollment)
Intervention acceptability as assessed by the Abbreviated Acceptability Rating Profile
Time Frame: Post intervention (weeks 4-8 after study enrollment)
Patient and caregiver acceptability of the newly developed intervention, as evidenced by the Abbreviated Acceptability Rating Profile. Scores range from 8-48, with higher scores indicating greater acceptability. Scores equal to or greater than 30 indicate good acceptability per published standards.
Post intervention (weeks 4-8 after study enrollment)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
