Although we tried to use a randomized sample in the experimental and control groups, however, given the small sample size, randomization may not assure a balance between arms.
To the best of our knowledge, this study is the first to use direct observation of patient care to describe the quality of HIV/AIDS care in the context of task-shifting in a highly resource-constrained environment, using a randomized national sample of providers.
Subjects aged ≥60 years were selected using a randomized, clustered sampling process.
All participants were selected using a randomized cluster sampling method; cases were the outpatient housewives, aged between 20 and 55 years.
We investigated 3133 participants aged 18 80 years in Shanghai, which were sampled using a randomized, stratified, multi-stage sampling method.
Using a randomized split of the sample, we performed exploratory factor analysis (EFA) on Group 1 (n = 459) and confirmatory factor analysis (CFA) on Group 2 (n = 459).
Specifically, for each model, the relevant samples were randomly divided into a training group (two-thirds of available samples) and a test group (one-third of available samples), using a randomized block method to ensure even division between the groups of CID and AD samples.
The intervention condition will be compared to a usual care control condition using a randomized design and a probabilistic sample of men and women.
Therefore, the present study addresses this gap in the research by examining the effects of a TWH intervention that addresses work-life stress and safety on worker health, well-being, and safety outcomes using a randomized control design in a sample of construction workers.
