Abstract

Introduction: Short message service (SMS), or text-based, health interventions offer a promising opportunity to deliver health education and have been shown to improve diet and exercise. However, few are theory-based or target low-income parents. This pilot study, informed by the Theory of Planned Behavior (TPB), primarily sought to determine if health education delivered via SMS was feasible and acceptable to low-income parents of young children.

Methods: Using a one-group, pre- to post-test study design to assess a 12-week SMS-based health education program, parents enrolled in a health-related program at an early childhood development center for low-income families were sent three text messages per week that corresponded to a weekly diet or physical activity-related theme. Surveys assessed pre-post changes in TPB constructs and collected program feedback.

Results: Among the 119 eligible parents invited to participate, 109 were sent all text messages for the duration of the study. Participants were mostly Black (98.9%), 25-39 years old (83.9%), female (93.8%), and in single-parent households (63.8%). More than half (n = 59) completed the pre-survey, answered a bi-directional program text, or completed the post-survey. Twelve participants completed both the pre- and post-survey and at least one bi-directional text. Post-survey results revealed that most participants liked the program design and enjoyed their experience with the program.

Conclusions: SMS-based interventions can simplify delivery of health information to low-income parents of young children. Although engagement was low, retention was high, and feedback was largely positive.
