I need assistance with a question for my homework assignment, based on the Shahnazi et al. (2016) article "Effect of educational intervention on perceived susceptibility self-efficacy and DMFT of pregnant women" (doi:10.5812/ircmj.24960) that was assigned for the NHS-8070 class for Capella University. REVISED QUESTION below--

1. Describe, interpret, and critique the study's results from the analysis, including addressing issues of significance, type I and II errors, confidence intervals, and effect sizes.
2. ***Here is my revised question***:
3. In general, for a research quasi-experimental study, is it possible for the researchers to assert that the study IS significant and applicable to other settings WITHOUT reporting the confidence levels and effect sizes? Only p values are reported from the independent t-test, repeated measure ANOVA, and paired t-test.
4. My thought is NO, the authors cannot assert that the study has this significance without reporting the confidence levels and effect sizes too.
