Exploring the Role of Mindfulness Training in the Promotion of Medication Adherence in Heart Failure Outpatients.

This study investigated the feasibility and acceptability of a phone-delivered mindfulness intervention to improve medication adherence among outpatients with heart failure.

Study Overview

Status

Completed

Detailed Description

This project seeked to study the role of mindfulness training (MT) in the promotion of medication adherence among patients with chronic heart failure (HF). A prospective pre/post design study was conducted among 50 stable outpatients with HF and sub-optimal self-reported medication adherence. MT sessions (one 30-min session/week over 8 weeks) were phone-delivered by qualified mindfulness instructors. Assessments were conducted at baseline, 3 months (end of the intervention) and 6 months since baseline. The primary outcomes were feasibility and acceptability. We hypothesized we would meet recruitment goals (n=50) within the study timeline, with < 20% drop out rates by the end of the study and that > 80% of participants would report high (=grade 5) enjoyment ratings on a self-report intervention enjoyment scale (range:1 to 5). Secondary outcomes were self-reported and objectively assessed medication adherence and functional capacity (a clinical marker of medication adherence. We hypothesized we would observe significant pre-post intervention improvements in medication adherence and functional capacity. Additional outcomes included possible mediators of intervention effect, i.e., cognitive function, mood, sleep quality, and interoceptive awareness.

Experimental: Mindfulness Training (MT)
Eight, 30-minute phone delivered MT sessions once a week for 8 weeks
Participants assigned to the MT condition will receive a phone-delivered 30-minute mindfulness training once a week for 8 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Retention Rate
Time Frame: 3 months, 6 months
Percentage of participants retained in the study (n enrolled/n retained X 100)
3 months, 6 months
Intervention Acceptability
Time Frame: 3 months
Self-reported intervention enjoyment scale (1 = did not enjoy to 5 = enjoyed very much). Scores range from 1 to 5; higher scores mean a better outcome. The metric for this study was the percentage of participants indicating high intervention enjoyment (a score of 5).
3 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Self-reported Medication Adherence
Time Frame: baseline, 3 months, 6 months
The Voils extent of non-adherence scale ranges from 1-5. Higher scores represent greater non-adherence.
baseline, 3 months, 6 months
Objectively-assessed Medication Adherence
Time Frame: baseline, 3 months, 6 months
Medication Event Monitoring Systems (MEMS). Proportion of medication taken/medication prescribed x 100, averaged over 30 days. Range is 0-100%. Lower values indicate worse adherence.
baseline, 3 months, 6 months
Functional Capacity
Time Frame: baseline, 3 months, 6 months
6-min walk test (6MWT) distance. The 6 min walk test measures the distance a patient can walk on a level course in 6 min. It is a measure of functional capacity that correlates with peak oxygen uptake and is positively associated with survival in patients with cardiovascular disease. A higher value (in meters) indicates better functional capacity. The 6MWT distance in healthy adults has been reported to range from 400 to 700 meters.
baseline, 3 months, 6 months

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
The Flanker Inhibitory Control and Attention Test
Time Frame: baseline, 3 months, 6 months

Cognitive function was assessed using the NIH Toolbox Fluid Cognition Battery. Each neurocognitive test was independently completed by study participants (3-5 minutes each) using a study tablet after a baseline practice trial. For each cognitive measure we report age-adjusted scores, which are automatically generated by the NIH Toolbox software. For all measures, higher scores indicate better cognitive performance.

The Flanker Inhibitory Control and Attention Test is a measure of executive function, attention and inhibitory control. Participants are instructed to focus on a stimulus while inhibiting attention to another stimulus (arrows). Sometimes the middle stimulus points in the same direction as the "flankers" (congruent) and sometimes in the opposite direction (incongruent) over 20 trials.

baseline, 3 months, 6 months
The Dimensional Change Card Sort Test
Time Frame: Baseline, 3 months, 6 months
The Dimensional Change Card Sort Test is a measure of cognitive flexibility and attention. Two target pictures are presented that vary along two dimensions (e.g., shape and color). Participants are asked to match a series of bivalent test pictures (e.g., yellow balls and blue trucks) to the target pictures, first according to one dimension (e.g., color) and then, after a number of trials, according to the other dimension (e.g., shape). The relevant dimension for sorting is indicated by a cue word (e.g., "shape" or "color") that appears on the screen for all participants. Age-adjusted scores are calculated automatically by the NIH Toolbox software. Higher scores indicate better function.
Baseline, 3 months, 6 months
Oral Symbol Digit Test
Time Frame: baseline, 3 months, 6 months
The Oral Symbol digit test is a measure of working memory and processing speed. A key with nine abstract symbols is presented - each paired with a number between 1 and 9. Participants are asked to verbally indicate which numbers go with the symbols that are presented in a long string on the computer screen. The participant is given 120 seconds to call out as many numbers that go with the corresponding symbols as he/she can - in order, without skipping any. Age-adjusted scores were calculated automatically by the NIH Toolbox software. Higher scores indicate better function.
baseline, 3 months, 6 months
Picture Sequence Memory Test
Time Frame: baseline, 3 months, 6 months

The Picture Sequence Memory Test is a measure of episodic memory. Sequences of pictured objects and activities are presented in a particular order. The participants are asked to reproduce the sequence of pictures that is shown on the screen. Participants respond by dragging pictures from the yellow box on the screen into the gray boxes on the screen.

Age-adjusted scores were calculated automatically by the NIH Toolbox software. Higher scores indicate better function.

baseline, 3 months, 6 months
List Sorting Working Memory Test
Time Frame: baseline, 3 months, 6 months
The List Sorting Working Memory Test is a measure of working memory. Pictures of foods and animals are displayed with accompanying audio recording and written text (e.g., "elephant"), and the participant is asked to say the items back in size order from smallest to largest, first within a single dimension (either animals or foods) and then on two dimensions (foods, then animals). Age-adjusted scores were calculated automatically by the NIH Toolbox software. Higher scores indicate better function.
baseline, 3 months, 6 months
Depressive Symptoms
Time Frame: baseline, 3 months, 6 months
Hospital Anxiety and Depression Scale depression scores. Score range 0-21. Higher scores indicate greater psychological morbidity.
baseline, 3 months, 6 months
Sleep Quality
Time Frame: baseline, 3 months, 6 months
Pittsburgh Sleep Quality Index. Self-report measure of sleep quality and quantity. Higher scores indicate better sleep quality and quantity. The overall score range is 0-21.
baseline, 3 months, 6 months
Interoceptive Awareness: Noticing Score
Time Frame: baseline, 3 months, 6 months

The Multidimensional Assessment of Interoceptive Awareness (MAIA) is a 32-item, self-report measure composed of eight individual scales, specifically: Noticing; Not Distracting; Not-Worrying; Attention Regulation; Emotional Awareness; Self-Regulation; Body Listening; and Trusting. Items are rated on a 6-point Likert scale (0-5) with '0' indicating 'Never' and '5' indicating 'Always'. For each subscale, items were summed; higher scores indicate higher levels of interoceptive awareness. This instrument has adequate to excellent internal-consistency reliability, with Cronbach's alphas between 0.66 and 0.87, and > 0.70 for five of the eight scales.

The theoretical range for the noticing subscale score was 0-20.
