Assessing the National Cancer Institute's SmokefreeMOM Text-Messaging Program for Pregnant Smokers: Pilot Randomized Trial.

BACKGROUND

Automated text messages on mobile phones have been found to be effective for smoking cessation in adult smokers.

OBJECTIVE

This study aims to test the acceptability and feasibility of SmokefreeMOM, a national smoking cessation text-messaging program for pregnant smokers.

METHODS

Participants were recruited from prenatal care and randomized to receive SmokefreeMOM (n=55), an automated smoking cessation text-messaging program, or a control text message quitline referral (n=44). Participants were surveyed by phone at baseline and at 1 month and 3 months after enrollment.

RESULTS

Results indicate that the SmokefreeMOM program was highly rated overall and rated more favorably than the control condition in its helpfulness at 3-month follow-up (P<.01) and in its frequency of messaging at both 1-month and 3-month follow-ups (P<.001, P<.01, respectively). Despite the presence of technical problems, the vast majority of intervention participants read all program messages, and few participants unsubscribed from the program. There were no significant differences between groups on the use of extra treatment resources or on smoking-related outcomes. However, at the 3-month follow-up, some outcomes favored the intervention group.

CONCLUSIONS

SmokefreeMOM is acceptable for pregnant smokers. It is recommended that SmokefreeMOM be further refined and evaluated.
