Study summary

The primary objective of the proposed study is to examine the effectiveness of a culturally adapted digital program of cognitive behavioral therapy for insomnia (CBT-I) compared to minimally enhanced usual care (mEUC) on primary outcomes: reduction in insomnia symptoms at 9 weeks and 6 months post-intervention, using a standard scale among Spanish-Speaking Latina/o adults with chronic insomnia.

Read the detailed description

Chronic insomnia is associated with significant public health burden and most adults seek care for insomnia in the primary care setting. While Latina/os are at greater risk for insomnia than non-Hispanic Whites, access to the recommended first-line of treatment, cognitive behavioral therapy for insomnia, is limited especially for Spanish-speakers. Recent advances in health information technology such as self-guided digital health treatments represent an innovative and scalable means to address the supply and demand imbalance that perpetuate mental health care disparities, however its implementation in underserved communities remains elusive. The purpose of this study is to compare the effectiveness of a culturally adapted digital version of Cognitive Behavioral Therapy for Insomnia with minimally enhanced usual care on reduction of insomnia symptoms among Spanish-speaking Latina/os adults with chronic insomnia. The study will also examine barriers and facilitators to implementation, and examine cost-effectiveness of the intervention.

Study arms

  • Experimental
    Culturally adapted digital cognitive behavioral therapy for insomnia (CBT-I) (Somryst)

    Somryst is an FDA-authorized digital cognitive behavioral therapy for insomnia (CBT-I) program that has been translated and culturally adapted for Spanish speakers. Group will have access to this culturally-adapted Somryst, along with the usual care provided by their primary care provider, and will be provided a sleep hygiene brochure during group assignment.

  • Active comparator
    Minimally Enhanced Usual Care (mEUC)

    Usual care by their primary care provider and a sleep hygiene brochure. Group will continue their typical standard care with their primary care provider, which may include pharmacotherapy. In addition, we will provide a sleep hygiene brochure during group assignment.

Interventions

  • BehavioralDigital cognitive behavioral therapy for insomnia (CBT-I) program

    A self-guided digital program of CBT-I (Somryst) that has been culturally adapted for Spanish-language speakers. Somryst is an interactive and tailored mobile-based program modeled on the primary tenets of face-to-face CBT-I. Patients will be asked to complete six cores (main intervention content) during the 9-week intervention period. The cores provide key content across six domains including behavioral (sleep restriction, stimulus control), cognitive (cognitive restricting), educational (sleep hygiene), overview, and consolidation/relapse prevention.

  • BehavioralMinimally Enhanced Usual Care (mEUC)

    A minimally enhanced usual care, which will include usual care by patients' Primary Care Provider and a sleep hygiene brochure.

What researchers measure

Primary outcomes

  1. Change in Mean Insomnia Severity Index Score (ISI)

    ISI is a 7-item self-report scale measuring insomnia symptom severity in the last 2 weeks; summed score ranges 0-28, increasing score associated with increasing severity.

    Time frame: Baseline to post-intervention (9 weeks)

  2. Change in Mean Insomnia Severity Index Score (ISI)

    ISI is a 7-item self-report scale measuring insomnia symptom severity in the last 2 weeks; summed score ranges 0-28, increasing score associated with increasing severity.

    Time frame: Baseline to 6 months post intervention

Secondary outcomes

  1. Change in Mean Quality of Life Score (Short-Form 12 [SF-12], MCS, Mental Component Score)

    Short Form (SF)-12 is a 12-item self-report inventory that generically measures quality of life; yields a measure of global health-related wellbeing as 8 domain-specific subscores on a 0-100 scale, increasing score reflects less dysfunction, impairment, or pain. Reporting change in mean mental health component score.

    Time frame: Baseline to post-intervention (9 weeks)

  2. Change in Mean Daytime Sleepiness- Epworth Sleepiness Scale (ESS)

    ESS is an 8-item brief self-report scale of daytime sleepiness; summed scores range 0-24, where increasing scores constitute greater sleepiness, and a score \> 11 represents elevated daytime sleepiness.

    Time frame: Baseline to post-intervention (9 weeks)

    Time frame: Baseline to post-intervention (9 weeks)

  2. Change in Mean Self-reported Wake After Sleep Onset
