Effects of Framed Mobile Messages on Beliefs, Intentions, Adherence, and Asthma Control: A Randomized Trial

We aimed to examine the effects of framed mobile messages (messages emphasizing losses or gains because of a behavior) on young adults' beliefs about their daily Inhaled Corticosteroids (ICS), intentions to take their ICS, adherence, and asthma control. College students (18-29 years) who owned a mobile phone and had a diagnosis of asthma with a prescription for an ICS were recruited. Participants (n = 43) were randomized to receive either gain- or loss-framed mobile messages three times per week for eight weeks. Engagement rates with messages were calculated. Outcomes included beliefs, intentions, adherence, and asthma control. Data collection was performed at baseline, week 4, and week 8. Mixed-design ANOVA assessed whether outcomes improved differentially from baseline to week eight between gain- and loss-framed groups. Twenty-two participants were randomly assigned to the gain-framed group and 21 to the loss-framed group. There was a 100% retention rate. The engagement rate with the text messages was 85.9%. There was a significant difference in participants' intentions to take medication and asthma control from baseline. There were no significant changes in other outcomes from baseline. There was no difference in changes in all outcomes between participants receiving gain- versus loss-framed messages. Framed mobile messages improved young adults' asthma control and intentions to take their medication as prescribed.

Predictors of adherence to controller medication in urban African American emerging adults with uncontrolled persistent asthma

BACKGROUND

African American emerging adults tend to have low adherence to asthma controller medication, as well as a disproportionate burden of asthma morbidity and mortality. This study explored constructs from the Information-Motivation-Behavioral Skills model as predictors of controller medication adherence in urban African Americans ages 18-29 (N=152) with uncontrolled asthma using multiple measures of self-reported adherence.

METHODS

Structural equation modeling (SEM) was employed to test the hypothesized mediation model that specified the relationship among psychological distress, substance use, asthma knowledge, motivation, self-efficacy, and adherence.

RESULTS

Results suggested that motivation is an important predictor of adherence to medication; moreover, higher self-efficacy was associated with higher motivation. Results also highlighted psychological distress as an important intervention target to improve medication adherence in emerging adults.

CONCLUSIONS

The model tested in this study may offer a feasible framework for beginning to understand adherence to controller medication in this population.

Exploring Barriers to Medication Adherence Among African American Emerging Adults With Uncontrolled Asthma

African American emerging adults (age 18-29 years) tend to have poor asthma outcomes, possibly due to poor adherence to medication. Few studies have explored barriers to controller adherence in this population. This study utilized electronic daily diaries to assess barriers to adherence and asthma symptoms among 141 African American emerging adults with uncontrolled persistent asthma and poor adherence. Participants reported symptoms M = 3.43 days (of 7 days). They reported unintentional (e.g., forgetting) and intentional (e.g., choosing not to take) barriers to adherence, but forgetting, being too busy, and sleeping through a dose were the most common. Significant correlations were found between symptoms and barriers, as well as asthma control and medication adherence in the expected directions. Asthma symptoms and number of barriers were significant predictors of asthma control. Existing intervention strategies such as text-messaging may prove effective to address these barriers, but measuring and addressing adherence remains complex.

Prevalence and predictors of adherence to inhaled corticosteroids in young adults (15-30 years) with asthma: a systematic review and meta-analysis

Objective: Adherence to inhaled corticosteroids (ICS) is an essential part of asthma management throughout the lifespan; however, this may be particularly challenging during the transition into adulthood. This systematic review aimed to determine the prevalence and predictors of adherence to ICS in emerging adulthood.Data sources: MEDLINE, PsycINFO, EMBASE, Scopus, and CINAHL were searched with search terms for asthma, ICS, adherence, young adults, and predictors combined.Study selection: Studies with participants with diagnosed asthma, currently prescribed ICS, a mean age between 15 and 30 years and reporting the prevalence and/or assessing predictor(s) of adherence using quantitative methods were included.Results: Twenty-nine studies were identified for inclusion (K = 29, N = 187 401). A random effect meta-analysis revealed the pooled prevalence of adherence was 28% (95% CI = 20-38%, k = 16) in studies that provided quantitative information on adherence. Adherence was higher in studies with a mean age <18 years (36%; 95% CI = 36-37%, k = 4). Studies using self-report measures provided higher estimates of adherence (35%; 95% CI = 28-42%, k = 10) than studies using pharmacy refill data (20%; 95% CI = 9-38%, k = 6). A narrative review identified personality, illness perceptions, and treatment beliefs as potentially important predictors of adherence.Conclusion: Adherence is sub-optimal during emerging adulthood, particularly after age 18. More reliable and objective measures are needed to precisely characterize adherence. Greater research and practice attention to emerging adulthood are needed to guide self-management support in those living with asthma at this important lifespan stage.Systematic review registration number: CRD42018092401.

The Detroit Young Adult Asthma Project: Proposal for a Multicomponent Technology Intervention for African American Emerging Adults With Asthma

Background

Racial and ethnic minority youth have poorer asthma status than white youth, even after controlling for socioeconomic variables. Proper use of asthma controller medications is critical in reducing asthma mortality and morbidity. The clinical consequences of poor asthma management include increased illness complications, excessive functional morbidity, and fatal asthma attacks. There are significant limitations in research on interventions to improve asthma management in racial minority populations, particularly minority adolescents and young adults, although illness management tends to deteriorate after adolescence during emerging adulthood, the unique developmental period beyond adolescence but before adulthood.

Objective

The objective of the pilot study was to test the feasibility, acceptability, and signals of efficacy of an intervention targeting adherence to controller medication in African American youth (ages 18-29) with asthma. All elements of the protocol were piloted in a National Heart, Lung, and Blood Institute (NHLBI)–funded pilot study (1R34HL107664 MacDonell). Results suggested feasibility and acceptability of the protocol as well as proof of concept. We are now ready to test the intervention in a larger randomized clinical trial.

Methods

The proposed study will include 192 African American emerging adults with moderate to severe persistent asthma and low controller medication adherence recruited from clinic, emergency department, and community settings. Half of the sample will be randomized to receive a multicomponent technology-based intervention targeting adherence to daily controller medication. The multicomponent technology-based intervention consists of 2 components: (1) 2 sessions of computer-delivered motivational interviewing targeting medication adherence and (2) individualized text messaging focused on medication adherence between the sessions. Text messages will be individualized based on ecological momentary assessment. The remaining participants will complete a series of computer-delivered asthma education modules matched for length, location, and method of delivery of the intervention session. Control participants will also receive text messages between intervention sessions. Message content will be the same for all control participants and contain general facts about asthma (not tailored).

Results

It is hypothesized that youth randomized to multicomponent technology-based intervention will show improvements in medication adherence (primary outcome) and asthma control (secondary outcome) compared with comparison condition at all postintervention follow-ups (3, 6, 9, and 12 months). The proposed study was funded by NHLBI from September 1, 2016 through August 31, 2021.

Conclusions

This project will test a brief, technology-based intervention specifically targeting adherence to asthma controller medications in an under-researched population, African American emerging adults. If successful, our multicomponent technology-based intervention aimed at improving adherence to asthma medications has the potential to improve quality of life of minority emerging adults with asthma at relatively low cost. It could eventually be integrated into clinical settings and practice to reach a large number of emerging adults with asthma.
