People are commonly found with eyes glued to their phones and other digital devices that are commonly available these days and there is a surge in mental health related issues and problems. You have already searched the current literature but unfortunately most studies had flaws that you could easily identify. You are considering doing your own research to explore the potential link. One of your fond memories of EPID1000 is the study designs you learned and now having the opportunity to put that knowledge into practice, really excites you. You think about six study designs (listed below) and what each would involve. For example, which aspect of mental health you will specifically focus on, how you will carry out the study, what sort of study participants you will need for each design, what information should be collected to investigate this link, what measure of association/effect can be obtained from each design, what will be one specific confounding factor individually for each of the six study designs and how or why each confounder will affect the findings of your study for every design. There will be no mark for repetition of same confounding factor for more than one study design. You will briefly describe the above aspects as one paragraph for each of the following designs while following the formatting & line-limit instructions provided below. You can use the review exercise (tutorial 11) as a general guide but address only those aspects that are listed above. Please also re-visit the weekly epidemiology ilectures on study designs. a) Cross-sectional study b) Case Control study c) Prospective Cohort study. d) Retrospective Cohort study. e) Quasi-experimental study. f) Randomized Controlled Trial. (No need to worry about the ethics for e and f parts); this is a hypothetical exercise to assess your understanding of various study designs).

No marks will be given for writing general design features from ilectures. We want you to ‘apply’ your knowledge of study designs in light of the above given scenario/description. Write in direct language e.g. I will carry out this study by……. Q1 Note 2: Formatting & Line limit: For each of the six parts please use Times New Roman size 12 font, normal page borders and 10 lines maximum for each part, (10 lines DO NOT mean ten sentences or ten statements). Please do not change the margins of this document. Failure to comply will result in penalty. There are no formatting requirements for other questions. Instructions for the Data Analysis Questions listed below: a. You must provide SPSS output under every question along with your answer as No SPSS output = No mark b. You must include your assessment of statistical significance for every question. c. You will use your own sample of 450 from the provided dataset (how to video & instructions provided separately). d. You will NOT test any ASSUMPTION for any question: Please do not waste your time in testing any assumptions and/or changing plans accordingly. You may incur penalty for doing so. We want you to choose a suitable test for every question as if your data met all required assumptions. e. Copy and paste SPSS output under every question along with your written answer on this template otherwise we will not mark your answer/s. Upload the completed template ONLY (No zip folder, no Pages, no other files) f. You can choose a different sample of 450 for every question or use the same sample throughout, it is up to you (More info & instructions are in the Submission guidelines & FAQs provided separately).
