Summary

This is a single site nonrandomized pilot clinical trial of the feasibility, acceptability, and efficacy of a combination treatment involving digital Cogmed working memory skills training, social support components, and memory strategy training to improve adherence to Cogmed in youth with sickle cell disease ages 7-16 years.

Detailed description

The primary objective of this study is to evaluate the feasibility of a novel approach to ameliorating cognitive deficits in children and adolescents with sickle cell disease (SCD). SCD is an understudied, life-limiting disease affecting 100,000 individuals in the United States and over 300,000 newborns globally every year. Youth with SCD are at substantial neurological risk given their increased likelihood of overt stroke and silent cerebral infarct. However, even individuals without signs of cerebral infarct exhibit lower cognitive performance compared to healthy siblings due in large part to non-stroke, disease effects on the central nervous system. Disease-related cognitive issues are diffuse but often affect working memory function. Very few studies have examined therapeutic approaches to treating cognitive deficits in SCD; however, recent research supports the use of a home-based, eHealth working memory training program (Cogmed). In a randomized controlled trial, Cogmed training (i.e., repeated and adaptive working memory skills practice) resulted in improved working memory but adherence to the intervention was low. Early engagement with the training program emerged as predictive of better adherence. Therefore, in an effort to promote engagement, an enhanced version of the program was developed that incorporates social support components (e.g., multifamily Cogmed Kickoff events, social incentives, peer navigator support) and memory strategy training. The study will evaluate the following specific aims in a single-arm pilot clinical trial: 1) Assess the feasibility of Cogmed+ (Cogmed plus social support components and memory strategy training) in youth with SCD; and 2) Determine the effect of Cogmed+ on rates of treatment adherence. In this study, 50 youth ages 7-16 with SCD will complete a cognitive screening, after which 30 participants with working memory deficits will proceed to the Cogmed+ program. Participants will complete Cogmed on a tablet device from home 3-5 times per week for 5-8 weeks. Participants will attend weekly videoconference calls with a Cogmed coach who will review training progress and teach memory strategies during four coaching calls (weeks 2-5). Outcomes will be assessed by examining the number of Cogmed sessions completed and rates of attendance to Cogmed Kickoff events and memory strategy training sessions. Results will also be compared to a historical comparison group of youth with SCD who completed the basic version of Cogmed. Findings will provide critical data regarding a novel strategy for improving access to an efficacious treatment for youth with SCD. If such an augmented approach proves beneficial, resultant data will inform a randomized controlled trial to examine the effectiveness of a stepped care model that selectively delivers more intensive Cogmed treatment packages only as needed. This line of investigation, which balances practical access and resource considerations, could serve as a scalable care model and ignite efforts to address SCD-related cognitive impairment for the millions of people living with SCD globally.

Interventions

Type	Name	Description
BEHAVIORAL	Cogmed+	Cogmed is a home-based, digital working memory training program compatible with tablet devices. The program, designed for children ages 7 and older, consists of engaging cognitive exercises that target skills involving visuospatial and verbal working memory. An essential component of Cogmed training involves assignment of an intervention "coach" who has access to detailed data on the user's training data. Families will have videoconference meetings once per week with an intervention coach to review progress, provide feedback and answer any questions that arise during treatment. In addition, participants' coaching calls will be supplemented with direct instruction on the use of memory strategies. Social support interventions will also be provided involving three primary approaches: (1) multi-family Cogmed Kickoff social events; (2) social incentives; and (3) peer navigator support.
