Designing and validation of text messages for m-Health intervention for tobacco cessation and management.

BACKGROUND
Tobacco is a growing epidemic and tobacco-related death results in health consequences and lost economic opportunities. Tobacco cessation efforts mandate the use of multiple strategies to bring about behaviour change.


AIM
To develop and validate health promotive text messages using transtheoretical model and prospect theory for behaviour change.


SETTINGS AND DESIGN
The present observational study was conducted in a tertiary care hospital, Delhi among patients reporting at Tobacco Cessation Centre (TCC).


METHODS
The study was divided into two phases: first involved development of text messages in local language (Hindi) using a sound theoretical basis (TTM and prospect theory) and second phase dealt with validation of the developed text messages by patients and experts in the field of tobacco cessation.


STATISTICAL ANALYSIS
Descriptive statistics was obtained using the SPSS version 17.


RESULTS
The sample comprised 20 males and 6 females. Average appeal score ranged from 6.1 to 9.6 (54 messages). Forty two messages out of a total of 54 messages were found to be appropriate after validation by the experts. Mean words of the final messages (42 messages) was 24.5 ± 1.3. Two hundred ninety one (90%) out of a total of 324 questionnaires showed adequate understanding of message as assessed by the reviewers.


CONCLUSIONS
The current effort developed and validated health promotive text messages package to aid in tobacco cessation. The preventive text messages were grounded in evidence and sound theoretical basis and followed a standard validating procedure leading to satisfactory understanding and appeal in all domains.
