STUDY 1.

Pre- and post-intervention values (standard error).

Intervention n=235

Mean (SD) Pre-test 6.66 (0.15)

Mean (SD) Post-test 5.74 (0.17)

P value* <0.0001

Waiting room control n=96

Mean (SD) Pre 6.31 (0.26)

Mean (SD) Post 6.39 (0.27)

P value* <0.516

*Significance of pre- to post-intervention change.

STUDY 2 n=59

Pre- and post-intervention values (standard error).

Intervention

Mean (SD) Pre-test 3.15 (2.8)

Mean (SD) Post-test 2.47 (2.6)

Difference -0.69

t -3.30

p 0.001

Significance set at <0.05.

Experiment wide alpha was set at p< 0.05 such that each test had to reach a level of p <0.004 (0.05/13) to be considered statistically significant.; one-tailed. One-tailed tests were used for hypothesis testing.

I am looking at the overall success of the intervention and have to use just these two papers to discuss the intervention itself. I need to discuss the p values which I understand, but also the CIs! I need to make sense of both CIs and what this means to the actual intervention… Hope this makes sense!
