This study examines the efficacy of using text message reminders to increase attendance and completion in a sample of parents at high risk for child maltreatment participating in a 10-week parent training program. Study participants (N = 117) were randomized to the Standard (control) or Text Message (intervention) group. Hierarchical regression models were used to test the relation between group and two outcomes—attendance and program completion—after controlling for demographics and baseline parenting stress scores. Attendance rates were similar for the Standard and Text Message groups, with no statistically significant differences in bivariate and multivariate analyses. Program completion rates were higher in the Text Message group than the Standard group in bivariate analysis. The final model testing the relation between the Text Message group and completion, after controlling for parenting stress, was statistically significant. Results suggest that sending text message reminders increased completion rates. The strategy appears to keep participants connected to the program, making them more likely to attend makeup sessions and fulfill requirements to complete the program. Results are promising regarding the use of text messages to improve parent training program completion rates. Future research should further evaluate this strategy in other parent training programs.
