Developing and Testing of Behavioral Intervention Programs for Hispanic Cancer Survivors With Insomnia

This study focuses on improving insomnia among Hispanic cancer survivors by adapting and testing two culturally appropriate sleep programs. First, up to 32 Hispanic cancer survivors will participate in four focus groups, with 6-8 participants per group, to provide feedback to help culturally adapt a Body-Mind Training (BMT) program and Cognitive Behavioral Therapy for Insomnia (CBT-I) in both English and Spanish. Eight of these participants will also complete individual interviews to provide additional feedback on the adapted programs. Second, 58 Hispanic cancer survivors with insomnia will participate in a randomized pilot study comparing BMT and CBT-I to determine whether the programs are feasible, acceptable, and practical for participants to complete. Third, the study will explore whether BMT and CBT-I improve insomnia, using both participant-reported insomnia symptoms and objective sleep measures collected with a wrist-worn activity monitor. Sleep will be assessed before the program, shortly after it ends, and three months later. The findings will help inform the design of a larger study comparing these approaches for treating insomnia among Hispanic cancer survivors.

Body-Mind Training: A 12-week, group-based program delivered virtually twice per week. Sessions combine gentle body movements, breathing exercises, meditation, and relaxation techniques designed to support sleep and overall well-being. Participants are also encouraged to practice at home between sessions.

Behavioral: Body Mind Training

Cognitive Behavioral Therapy for Insomnia (CBT-I): An 8-week, group-based program delivered virtually once per week. Sessions include sleep education, sleep restriction, stimulus control, cognitive therapy, relaxation, sleep hygiene, and relapse prevention. Participants are encouraged to practice the skills between sessions.

Behavioral: Cognitive Behavioral Therapy - Insomnia

Body-Mind Training (BMT): A 12-week, group-based program delivered by live videoconference twice per week for 60 minutes. Each session includes a warm-up, gentle body movements combined with meditation, breathing techniques, and relaxation exercises. Movements can be completed while seated or standing to support participant safety and different physical abilities. Participants will also receive instructional videos and a manual to support home practice and will be encouraged to practice for at least 30 minutes, three days per week. The final four weeks of the program will emphasize skill consolidation and continued practice.

Cognitive Behavioral Therapy for Insomnia (CBT-I): An 8-week, group-based program delivered by live videoconference once per week for 60 minutes by a licensed bilingual psychologist experienced in CBT-I. Sessions include sleep education, sleep restriction, stimulus control, cognitive therapy, relaxation, sleep hygiene, and relapse prevention. Participants will be encouraged to practice the skills learned during sessions for at least 30 minutes per day, three days per week.

Sleep self-efficacy will be measured with the sleep self-efficacy scale(SES). The SES is a 9-item self-report measure that assesses anindividual's confidence in their ability to achieve and maintain healthysleep. Items are rated on a 5-point Likert scale, with higher scoresindicating greater sleep self-efficacy.106 The SES has demonstratedexcellent internal consistency (Cronbach's α ≈ 0.90).

Plazo: Baseline, 1-2 weeks post-intervention, and 3 months post-intervention

Mindfulness will be measured with the Mindful Attention Awareness Scale (MAAS), a 15-item self-report measure that assesses dispositional mindfulness, specifically an individual's awareness of and attention to present-moment experiences. Items are rated on a 6-point Likert scale, with higher scores indicating greater mindfulness. The MAAS has demonstrated excellent internal consistency (Cronbach's α =0.80-0.90) and strong construct validity and is available in both English and Spanish

Quality of Life (QOL) will be assessed via the Functional Outcomes for Cancer Therapy - General (FACT-G). This measure consists of 27 items designed to measure four domains of quality of life in cancer patients: physical, social, emotional, and functional well-being. Coefficients of reliability and validity are uniformly high. The scale's ability to discriminate among patients based on disease stage, performance status rating (PSR), and hospitalization status supports its sensitivity. It has also demonstrated sensitivity to change over time. The FACT-G is available and validated in English and Spanish.

Plazo: Baseline, 1-2 weeks post-intervention, and 3 months post-intervention

Anxiety and depression will be measured with the Patient Health Questionnaire-4 (PHQ-4), a 4-item self-report measure that assesses symptoms of anxiety and depression over the past two weeks. It combines the 2-item Generalized Anxiety Disorder scale (GAD-2) and the 2-item Patient Health Questionnaire (PHQ-2), with higher scores indicating greater psychological distress. The PHQ-4 has demonstrated good internal consistency (Cronbach's α ≈ 0.81) and strong validity and is available in both English and Spanish.

Plazo: Baseline, 1-2 weeks post-intervention, and 3 months post-intervention

Perceived stress will be measured with the Perceived Stress Scale (PSS-10), a 10-item self-report measure that assesses the degree to which individuals perceive their lives as stressful during the past month. Items are rated on a 5-point Likert scale, with higher scores indicating greater perceived stress. The PSS-10 has demonstrated good internal consistency (Cronbach's α ≈ 0.78-0.91), strong construct validity, and is available in both English and Spanish.

Plazo: Baseline, 1-2 weeks post-intervention, and 3 months post-intervention

Fatigue will be assessed with the Functional Assessment of Chronic Illness - Fatigue (FACIT-F) Scale.120 This scale is frequently used with cancer survivors because it has established minimally important differences. This 13-item scale assesses the level of fatigue during usual activities over the past 7 days, with higher scores indicating less fatigue (score range=0-52; Cronbach's alpha=0.86). The FACIT-F is available in English and Spanish and validated in Spanish-speaking populations.

Plazo: Baseline

Comorbidities will be assessed with the Charlson Comorbidity Index. It is a weighted index that considers both the number and the seriousness of comorbid diseases. It consists of 19 items, each with an assigned weight from 1 to 6 according to the relative risk of dying within a year. In general, the absence of comorbidity is considered: 0-1 points; low comorbidity: 2 points; and high comorbidity:≥3 points.

Plazo: Baseline, 1-2 weeks post-intervention, and 3 months post-intervention

Acculturation will be measured with the Short Acculturation Scale for Hispanics (SASH). The 12-item scale (explaining 67.6% of the variance for Hispanics) correlates highly with the following validation criteria: respondents' generation, length of residence in the U.S., age at arrival, ethnic self-identification, and an acculturation index. The SASH is available and validated in English and Spanish.

Plazo: Within 24 hours after each BMT session, up to 24 sessions over 12 weeks.

Perceived exertion will be measured after each BMT session, with the classic Borg Rating of Perceived Exertion (RPE) scale, which is a 15-point scale (ranging from 6 to 20). It has been extensively tested and validated against physiological markers. This will be collected to ensure that the BMT intervention is perceived as being of mild to moderate intensity.

Plazo: During the first week of the intervention

Credibility/Expectancy Questionnaire (CEQ). The CEQ is a brief 6-item self-report measure assessing participants' perceived credibility of an intervention and expectations for improvement. It has demonstrated good internal consistency, with Cronbach's α generally ranging from 0.79-0.90 for credibility and 0.81-0.86 for expectancy, as well as good test-retest reliability.
