Mind Your Heart Intervention for American Indian Women (MYH)

5. května 2026 aktualizováno: University of North Carolina, Chapel Hill

MIND Your Heart Study for American Indian Women

The goal of this clinical trial is to learn if a culturally-adapted intervention can improve cardiovascular health in American Indian women.

The main questions it aims to answer are:

  • Can this intervention realistically work for American Indian women?
  • Do American Indian women find the intervention acceptable?
  • Does the intervention help improve cardiovascular health in American Indian women? Researchers will compare the intervention group to a control group (a group that does not receive the intervention) to see whether the cardiovascular health of the intervention group improves.

Participants will:

  • Attend 3 data collections over 3 months.
  • Be randomly assigned to either the intervention group or a control group.
  • (Intervention group participants) attend 8 weekly classes.

Baseline and Month 3
Change in body mass index (BMI)
Časové okno: Baseline, Week 8, and Month 3
Collection of weight and height to calculate BMI. Weight and height will be collected two times during each visit and averaged. The average weight and height will be calculated to determine BMI. BMI is calculated as weight (kg) / height (m^2).

Change in contextualized stress: burden
Časové okno: Baseline, Week 8, and Month 3
The investigators will measure burden (as a subscale of contextualized stress) using the Jackson, Hogue, Phillips (JHP) Contextualized Stress Measure (Gendered and Financial Stress) Burden Subscale. 17-item subscale of the JHP Contextualized Stress measure assessing chronic exposure to gendered and racialized stress. The burden subscale uses a 6-point Likert scale (1=Strongly Agree to 5=Strongly Disagree; 6=Not Applicable). Scores range from 17-102 with higher scores reflect a better outcome.
Baseline, Week 8, and Month 3
Change in perceived stress
Časové okno: Baseline, Week 8, and Month 3
Perceived stress will be measured using the Perceived Stress Scale (PSS), a 10-item scale assessing stress experiences over the preceding month. The PSS measures the frequency of feelings and thoughts using a 5-point Likert scale, where positive responses are scored in reverse. The PSS score is determined by totaling all responses and ranges from 0 to 40 with lower scores reflecting a better outcome.
Baseline, Week 8, and Month 3
Change in positive psychological well-being
Časové okno: Baseline, Week 8, and Month 3
Mental Health Continuum - Short Form (MHC-SF) measures positive emotions and comprises 14 items, representing emotional well-being, psychosocial well-being, and social well-being. On a 6-point Likert scale (0 = never; 5 = everyday), respondents indicate how often they felt various positive feelings in the past month and the extent of their agreement or disagreement with various statements indicative of psychosocial and social well-being. Possible scores for the MHC-SF range from 0 - 70. Higher scores reflect a better outcome.
Baseline, Week 8, and Month 3
Change in positive emotions
Časové okno: Baseline, Week 8, and Month 3
The Modified Differential Emotions Scale (mDES) will be used to capture a broader array of emotions. Respondents rate the frequency of their experiences of 20 different emotions over the past two weeks, using a 5-point scale (0 = not at all; 4 = most of the time). Items are summed for both positive and negative emotions (both ranging from 0 - 40). Higher scores on the positive subscale indicate more positive emotions.
Baseline, Week 8, and Month 3
Change in negative emotions
Časové okno: Baseline, Week 8, and Month 3
The Modified Differential Emotions Scale (mDES) will be used to capture a broader array of emotions. Respondents rate the frequency of their experiences of 20 different emotions over the past two weeks, using a 5-point scale (0 = not at all; 4 = most of the time). Items are summed for both positive and negative emotions (both ranging from 0 - 40). Higher scores on the negative subscale indicate more negative emotions.
Baseline, Week 8, and Month 3
Change in carotenoid concentration
Časové okno: Baseline, Week 8, and Month 3
As a proxy for fruit and vegetable (F/V) intake, carotenoid concentrations in the skin will be measured using a portable, non-invasive, pressure-mediated reflection spectroscopy device called the Veggie Meter. The Veggie Meter produces a score from 0 to 800, with higher scores indicating greater skin carotenoid levels, which suggest a greater intake of fruits and vegetables.
Baseline, Week 8, and Month 3
Change in physical activity
Časové okno: Baseline, Week 8, and Month 3
Physical activity will be measured by total time being active. Investigators will collect activity data over a 7-day span using an accelerometer worn on the wrist.
Baseline, Week 8, and Month 3
Change in mindfulness self-regulation
Časové okno: Baseline, Week 8, and Month 3
Mindfulness self-regulation will be measured using the Five Facet Mindfulness Questionnaire (FFMQ), a 39-item, self-administered measure that assesses various aspects of mindfulness. Responses range from 1 (never/very rarely true) to 5 (almost always/always true) and are summed for a final score. Higher scores indicate greater mindfulness. Total scores range from 39 - 195.
Baseline, Week 8, and Month 3
Change in eating self-efficacy
Časové okno: Baseline, Week 8, and Month 3
Eating self-efficacy will be measured using the Eating Self-Efficacy Scale, a 25-item tool asking respondents to rate their difficulty in controlling eating from 1 (no difficulty) to 7 (most difficultly). Scores range from 25 - 175 with higher total scores indicating lower self-efficacy.
Baseline, Week 8, and Month 3
Change in exercise self-efficacy
Časové okno: Baseline, Week 8, and Month 3
Exercise self-efficacy will be measured using the Self-Efficacy for Exercise Scale (SEE), which records the strength of efficacy beliefs by 9 questions on a 11-point scale from 0 (cannot do at all) to 10 (certain can do). Scores range from 0 - 90 with higher scores indicating greater exercise self-efficacy.
Baseline, Week 8, and Month 3
Change in contextualized stress: stress states
Časové okno: Baseline, Week 8, and Month 3
The investigators will measure stress states (as a subscale of contextualized stress) using the Jackson, Hogue, Phillips (JHP) Contextualized Stress Measure (Gendered and Financial Stress) Stress States Subscale. 4-item subscale of the JHP Contextualized Stress assessing chronic exposure to gendered and racialized stress. The stress states subscale uses a 6-point Likert scale (1=Strongly Agree to 5=Strongly Disagree; 6=Not Applicable). Higher scores indicate greater stress.
Baseline, Week 8, and Month 3
Change in Super Woman Schema (SWS)
Časové okno: Baseline, Week 8, and Month 3
35-item measures 5 dimensions of internalized strength, emotion suppression, vulnerability resistance, motivation, and caretaking. Items are summed using a Likert scale (0=not true to 4=true all the time). Low SWS = 0-36; Moderate SWS = 36-70; High SWS = 71-105. Higher scores indicate closer alignment to the schema.
Baseline, Week 8, and Month 3
