This pilot study's main goal is to develop and preliminarily test a technology-based intervention to improve asthma medication adherence in urban African American emerging adults (ages 18-29). It is hypothesized that youth randomized to MCTI for adherence will show improvements in motivation to adhere to asthma medications and self-reported adherence compared to the comparison condition at 1- and 3- month follow up.

Primary Outcome Measures:
- Change in medication adherence [ Time Frame: baseline, 1 month, 3 month ]Self-reported adherence to asthma controller medication(s) through questionnaire report and, at baseline and 3 months, 7 days of momentary (real time) sampling of adherence behavior via SMS text messaging.
- Change in motivation for medication adherence [ Time Frame: baseline, 1 month, 3 month ]Self-report of motivation to take asthma controller medications as prescribed.
Secondary Outcome Measures:
- Change in asthma knowledge [ Time Frame: baseline, 1 month, 3 month ]Knowledge of asthma and asthma medications
- Change in asthma medication confidence [ Time Frame: Baseline, 1 month, 3 month ]Confidence in ability to take asthma medications as prescribed.
- Change in asthma medication importance [ Time Frame: baseline, 1 month, 3 month ]Perceived importance of taking asthma medication as prescribed.
- Change in asthma control [ Time Frame: baseline, 1 month, 3 month ]Self-reported asthma control (symptom prevalence, health care utilization)
- Change in barriers to taking medication [ Time Frame: baseline, 1 month, 3 months ]Self-report of barriers to taking medication. At baseline and 3 months, daily barriers to taking medications as reported in daily diary.
- Change in asthma anxiety [ Time Frame: baseline, 1 month, 3 month ]Feelings and anxiety associated with living with asthma.
- Change in asthma self-efficacy and attitude [ Time Frame: baseline, 1 month, 3 month ]Self-report of self-efficacy to manage asthma effectively; attitude towards asthma and asthma management.

Experimental: Multi-component, technology based intervention
2 tailored, computer-delivered motivational interviewing sessions targeting adherence to asthma control medications + tailored text messaged reminders to take medications between sessions.
Behavioral: Multi-component, technology based intervention
Motivational sessions were adapted from work done with young adults with HIV (MESA).
Active Comparator: Asthma education active control
Control condition consists of active control matched to intervention for delivery-method and time-- 2 sessions of computer-delivered asthma education + daily text messaged facts about asthma.
|Behavioral: Asthma education active control|
This study collected pilot data with a sample of 48 African American emerging adults with asthma with suboptimal medication adherence. Half of the sample were randomized to receive a multi-component technology-based intervention (MCTI) targeting adherence to daily controller medication. The MCTI consisted of two 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 were individualized based on Ecological Momentary Assessment (EMA). The remaining half of participants completed a series of computer-delivered asthma education modules matched for length, location, and method of delivery of the intervention session. Control participants also received text messages between intervention sessions. Message content was the same for all control participants and contain general facts about asthma (not tailored).
