    Personalisation is important in text messaging behaviour change support for adolescents

    The Journal of Medical Internet Research (JMIR) has published a New Zealand study looking at the effectiveness of text message programmes for overweight adolescents

    Adolescents are considered a hard to reach group and novel approaches are needed to encourage good health. Text messaging interventions have been reported as acceptable to adolescents but there is little evidence regarding the use of text messages with overweight and obese adolescents to support engagement or behaviour change after the conclusion of a healthy lifestyle program.

    The intent of this study was to explore the opinions of overweight adolescents and their parents regarding the use of text messages as a support during the maintenance period following an intervention.

    It reports on the findings from focus groups conducted with adolescents (n=12) and parents (n=13) who had completed an eight-week intensive intervention known as Curtin University’s Activity, Food and Attitudes Program (CAFAP).

    Focus groups were conducted three months after the CAFAP intervention. Participants were asked about their experiences of the prior three-month maintenance phase during which adolescents had received tri-weekly text messages based on the self-determination theory and goal-setting theory. Participants were asked about the style and content of text messages used as well as how they used the text messages. Data were analysed using content and thematic analyses.

    Two clear themes emerged from the focus groups relating to (1) what adolescents liked or thought they wanted in a text message to support behaviour change, and (2) how they experienced or responded to text messages.

    Within the “like/want” theme, there were five sub-themes relating to the overall tone of the text, frequency, timing, reference to long-term goals, and inclusion of practical tips.

    Within the “response to text” theme, there were four sub-themes describing a lack of motivation, barriers to change, feelings of shame, and perceived unfavourable comparison with other adolescents. What adolescents said they wanted in text messages often conflicted with their actual experiences. Parent reports provided a useful secondary view of adolescent experience.

    The conflicting views described in this study suggest that overweight and obese adolescents may not know or have the ability to articulate how they would best be supported with text messages during a healthy lifestyle maintenance phase. Further, supporting both engagement and behaviour change simultaneously with text messaging may not be possible.

    However, it was clear that to be effective intervention texts should be personalized as much as possible and minimize feelings of guilt and shame in overweight and obese adolescents.
