To evaluate the reach and effectiveness of a diabetes self-management DVD compared to classroom-based instruction.
A hybrid preference/randomized design was used with participants assigned to Choice v. Randomized and DVD v. Class conditions. One hundred and eighty-nine adults with type 2 diabetes participated. Key outcomes included self-management behaviours, process measures including DVD implementation and hypothesized mediators and clinical risk factors.
In the Choice condition, four times as many participants chose the mailed DVD as selected Class-based instruction (38.8 v. 9.4%, p<0.001). At the 6-month follow-up, the DVD produced results generally not significantly different than classroom-based instruction, but a combined Class plus DVD condition did not improve outcomes beyond those produced by the classes alone.
The DVD appears to have merit as an efficient and appealing alternative to brief classroom-based diabetes education, and the hybrid design is recommended to provide estimates of programme reach.
评估与课堂教学相比，糖尿病自我管理DVD的覆盖范围和效果。
采用混合偏好/随机设计，将参与者分配到选择组与随机组以及DVD组与课堂组。189名2型糖尿病成年人参与其中。主要结果包括自我管理行为、包括DVD实施情况的过程指标、假设的中介因素以及临床风险因素。
在选择组中，选择邮寄DVD的参与者人数是选择课堂教学参与者人数的四倍（38.8%对9.4%，p<0.001）。在6个月的随访中，DVD产生的结果总体上与课堂教学没有显著差异，但课堂加DVD的组合条件并没有比单独课堂教学产生更好的结果。
DVD似乎是一种有效的、有吸引力的替代简短课堂糖尿病教育的方式，建议采用混合设计来估计项目覆盖范围。
