Objective: To present feasibility data on SMART, the first teen worksite behavioural tobacco control intervention.Design: This phase II study was designed to estimate the efficacy and feasibility of a small scale, randomised, controlled intervention.Setting and subjects: This study, addressing youths aged 15-18 years, was implemented in four intervention and five control grocery stores that had an average of 44 eligible teens.Interventions: The tobacco use cessation and prevention interventions were based on social influences and peer leader models. Employee break rooms served as centres both for interactive activities including open houses, teen advisory boards, peer leader interviews, games and contests; and non-interactive interventions including bulletin boards and table tents with health messages and home mailings.Main process measures: Project staff collected process data on the extent of implementation of intervention activities, participation rates in activities, and contacts with peer leaders. On the final survey, teens reported on awareness of, participation in, and motivation for participating in project activities.Results: Indicators of feasibility were identified and discussed, including the number of activities implemented, teen participation, management support, cost, and barriers to and facilitators of implementation. During the 12 month intervention, a mean of 24.1 interactive activities and 55.3 non-interactive activities were implemented, and a mean 14.2% participation rate per activity per site was achieved. Eighty four per cent of teens reported being aware of SMART, and 39% reported participating in interactive and 67% in non-interactive activities.Conclusions: Teen smoking cessation rates in worksite programmes might be improved if they are conducted in companies where there is job stability and if teen programmes are part of worksite-wide tobacco control programmes that include both teens and adults.

When work-site health promotion programs incorporate theories of community organization, it is likely that employee ownership and participation are enhanced. This article reports quantitative indicators of involvement of Employee Advisory Board (EAB) members in the Treatwell 5-a-Day work-site study and examines relationships between EAB member time spent on project activities and work-site size, with indicators of the extent of implementation and variables associated with behavior change and work-site support. The results reported here indicate that a greater number of EAB member hours spent on program activities was associated with a greater number of events implemented. Smaller work-site size was associated with greater employee awareness of the program and greater participation in project activities as reported on the employee survey. These results suggest that the number of hours employee representatives devote to project activities might be an important consideration in planning employee involvement in work-site health promotion programming.

Purpose. To report findings from Treatwell 5-a-Day process tracking. Design. Worksites were randomly assigned to a minimal intervention control, worksite-only condition, or worksite-plus-family condition. Setting. Twenty-two small community health centers in Massachusetts. Subjects. Employees of the community health centers. Intervention. Both intervention conditions included the formation of employee advisory boards; activities such as nutrition discussions and taste tests targeting individual behavior change; and point-of-purchase labeling as an environmental strategy. Worksite-plus-family sites incorporated activities such as family contests, campaigns, and picnics. Measures. Documentation of the number and type of activities for extent of implementation; number of participants in activities for reach; program awareness and participation from the follow-up employee survey (n = 1306, representing 76% [range, 56%–100%] of the sample); change in fruit and vegetable consumption from a comparison between the follow-up and baseline surveys (n = 1359, representing 87% [range, 75%–100%] of the sample). Results. A higher number of activities per employee was significantly correlated with greater program awareness (. 68; p = . 006) and greater change in fruit and vegetable consumption (.55; p = .04). Greater participation in activities was significantly correlated with greater awareness (.67; p = .007), higher participation (.61; p = .02), and increase in fruit and vegetable consumption. (.55; p = .04). Conclusions. These results provide quantitative indicators of a dose-response relationship between the number of intervention activities per employee and higher percentage of employee participation and observed increases in fruit and vegetable consumption.

OBJECTIVES: We report on the results of the Treatwell 5-a-Day study, a worksite intervention aimed at increasing consumption of fruits and vegetables. METHODS: Twenty-two worksites were randomly assigned to 3 groups: (1) a minimal intervention control group, (2) a worksite intervention, and (3) a worksite-plus-family intervention. The interventions used community-organizing strategies and were structured to target multiple levels of influence, following a socioecological model. Data were collected by self-administered employee surveys before and after the intervention; the response rate was 87% (n = 1359) at baseline and 76% (n = 1306) at follow-up. A process tracking system was used to document intervention delivery. RESULTS: After control for worksite, gender, education, occupation, race/ethnicity, and living situation, total fruit and vegetable intake increased by 19% in the worksite-plus-family group, 7% in the worksite intervention group and 0% in the control group (P = .05). These changes reflect a one half serving increase among workers in the worksite-plus-family group compared with the control group (P = .018). CONCLUSIONS: The worksite-plus-family intervention was more successful in increasing fruit and vegetable consumption than was the worksite intervention. Worksite interventions involving family members appear to be a promising strategy for influencing workers' dietary habits.

LEARNING OUTCOME: A Field ScD, Harvard Med Sch, Boston MA.To evaluate bias and correlation of fruit and vegetable intakes estimated from the NCI 7-item screener compared with multiple 24-hr recalls.
