Secondhand Smoke Exposure and Young Children Researchers wanted to assess whether a theory-based, community health worker-delivered intervention for household smokers will lead to reduced secondhand smoke exposure to children in Chinese families. Smoking parents or caregivers who had a child aged 5 years or younger at home were randomly assigned to the intervention group that received information on smoking hygiene and the effects of secondhand smoke exposure delivered by community health workers or to the comparison group who received no additional information regarding secondhand smoke. At a 6-month follow-up, researchers assessed whether or not families had adopted any smoking restrictions at home. The results are shown in the following table. (Source: Abdullah et al., “Secondhand smoke exposure reduction intervention in Chinese households of young children: A randomized controlled trial,” Academic Pediatrics, vol. 15 (November-December 2015): 588-598, https://doi.org/10.1016/j. acap.2015.06.008)
a. What percentage of those receiving the intervention adopted smoking restrictions at home?
b. What percentage of those in the control group adopted smoking restrictions at home?
c. Based on this data, do you think the intervention may have been effective in promoting the adoption of smoking restrictions in the home?

- What does an A X B interaction mean in a two - way ANOVA? A. The affect of factor A depends on the level of factor B B. The main effects for Factors A and B must be short of significance C. There must be significant main effects for Factors A and B D. If there are significant main effects, they must be interpreted first before interpreting the interactionarrow_forwardIt would not be ethical to assign one group of children to smoke in order to study the effect. so, in lieu of this type of direct experimentation other forms of evidence are commonly accepted. Describe two of the common types of evidence that can be used to establish a cause-effect relationship when direct experimentation is not possible.arrow_forwardExplain the difference between a no-treatment control group and a placebo control group. Why are studies that compare a treatment condition to a placebo control group often associated with higher internal validity compared to studies with a no-treatment control?arrow_forward
