Evaluating Mailed Motivational, Individually Tailored Postcard Boosters for Promoting Girls' Postintervention Moderate-to-Vigorous Physical Activity.

ABSTRACT: Ways to optimize boosters to assist girls to attain adequate moderate-to-vigorous physical activity following an intervention are unknown.This study's purpose was to (a) determine whether girls receiving mailed motivational, individually tailored postcard boosters following a 17-week physical activity intervention would have greater moderate-to-vigorous physical activity at 9-month follow-up as compared to girls not receiving them and those in a control group and (b) evaluate girls' perceptions of the booster intervention.Sixth to seventh grade girls (n = 117) from two urban, Midwest schools with similar demographic characteristics participated in a 17-week physical activity intervention, and girls from a third school served as controls (n = 64). One (n = 54) of the two intervention schools was randomly assigned to receive 13 motivational, individually tailored postcards containing messages to encourage them to attain adequate physical activity during the postintervention period. Girls from the other intervention school (n = 63) did not receive postcards, and those in the control school did not receive any intervention. Moderate-to-vigorous physical activity was measured with accelerometers at postintervention and 9-month follow-up. Girls completed a postcard evaluation survey at 9-month follow-up.Moderate-to-vigorous physical activity decreased significantly from postintervention to 9-month follow-up with no between-group differences or group-by-time interaction effect. On the basis of the survey, 27 (64.3%) girls received all postcards. Only 15 (35.7%) read all that they had received. Evaluations of postcards tended to be favorable.Mailed booster postcards to promote physical activity among girls' postintervention were not effective. Strategies to achieve this objective warrant investigation.

Project description:BACKGROUND:Physical inactivity is high in Latinas, as are chronic health conditions. There is a need for physical activity (PA) interventions that are not only effective but have potential for cost-effective widespread dissemination. The purpose of this paper was to assess the costs and cost effectiveness of a Spanish-language print-based mail-delivered PA intervention that was linguistically and culturally adapted for Latinas. METHODS:Adult Latinas (N?=?266) were randomly assigned to receive mail-delivered individually tailored intervention materials or wellness information mailed on the same schedule (control). PA was assessed at baseline, six months (post-intervention) and 12 months (maintenance phase) using the 7-Day Physical Activity Recall Interview. Costs were calculated from a payer perspective, and included personnel time (wage, fringe, and overhead), materials, equipment, software, and postage costs. RESULTS:At six months, the PA intervention cost $29/person/month, compared to $15/person/month for wellness control. These costs fell to $17 and $9 at 12 months, respectively. Intervention participants increased their PA by an average of 72 min/week at six months and 94 min/week at 12 months, while wellness control participants increased their PA by an average of 30 min/week and 40 min/week, respectively. At six months, each minute increase in PA cost $0.18 in the intervention group compared to $0.23 in wellness control, which fell to $0.07 and $0.08 at 12 months, respectively. The incremental cost per increase in physical activity associated with the intervention was $0.15 at 6 months and $0.05 at 12 months. CONCLUSIONS:While the intervention was more costly than the wellness control, costs per minute of increase in PA were lower in the intervention. The print-based mail-delivered format has potential for broad, cost-effective dissemination, which could help address disparities in this at-risk population.

Project description:Background: Currently, the eHealth field calls for detailed descriptions of theory-based interventions in order to support improved design of such interventions. This article aims to provide a systematic description of the design rationale behind an interactive web-based tailored intervention promoting HPV-vaccination acceptability. Methods: The 6-step Intervention Mapping (IM) protocol was used to describe the design rationale. After the needs assessment in Step 1, intervention objectives were formulated in Step 2. In Step 3, we translated theoretical methods into practical applications, which were integrated into a coherent intervention in Step 4. In Step 5, we anticipated future implementation and adoption, and finally, an evaluation plan was generated in Step 6. Results: Walking through the various steps of IM resulted in a detailed description of the intervention. The needs assessment indicated HPV-vaccination uptake remaining lower than expected. Mothers play the most important role in decision-making about their daughter's immunization. However, they generally feel ambivalent after they made their decisions, and their decisions are based on rather unstable grounds. Therefore, intervention objectives were to improve HPV-vaccination uptake and informed decision-making, and to decrease decisional conflict among mothers of invited girls. Computer-tailoring was chosen as the main method; virtual assistants were chosen as a practical application to deliver interactive tailored feedback. To maximize compatibility with the needs of the target group, a user-centered design strategy by means of focus groups and online experiments was applied. In these, prototypes were tested and sequentially refined. Finally, efficacy, effectiveness, and acceptability of the intervention were tested in a randomized controlled trial. Results showed a significant positive effect of the intervention on informed decision-making, decisional conflict, and nearly all determinants of HPV-vaccination uptake (P < 0.001). Mothers evaluated the intervention as highly positive. Discussion: Using IM led to an innovative effective intervention for promoting HPV-vaccination acceptability. The intervention maps will aid in interpreting the results of our evaluation studies. Moreover, it will ease the comparison of design rationales across interventions, and may provide leads for the development of other eHealth interventions. This paper adds to the plea for systematic reporting of design rationales constituting the process of developing interventions.
