Evaluate the article "A healthy start: promoting mental health and wellbeing in the early primary school years" by Carmel Cefai & Liberato Camilleri (2015) by answering the questions below.

1. Was the rationale for carrying out the study compelling? For example, did the authors make any unsupported assertions or unjustified assumptions?
2. Was the research design appropriate for the research questions, predictions or hypotheses that were tested in the study?
3. Did the study suffer from any methodological shortcomings which might colour one's interpretation of the results? For example, suppose the authors generalised the results to the wider population (if applicable). If so, does the participant group seem large enough to permit this? Were there any other specific characteristics of the participants (e.g., educational level, cultural background) which might have affected the validity of the study?
4. Was a control group used (if applicable)?
5. Was the data-collection process problematic in any way (e.g., choice of materials, type of procedure used, management of data, involvement of the researcher)?
6. Was the authors' analysis of their data appropriate (e.g., choice of statistical test(s))?
7. Was the authors' interpretation of their findings plausible? In particular, is there another explanation for their results that seems just as good (or even better)?
8. Would it be possible for someone else to replicate the study easily (if applicable)?
