Posted: Mon Aug 08, 2022 7:03 am
Hi, this is Hakimeh.
I am a new learner of repeated measurement multilevel modeling.
Kindly, I seek your advice to design the following research appropriately.
Research objectives:
1) To explore the variation of patterns of kids’ smartphone usage during typical everyday life in comparison to travel time
2) To explore the association of the above-mentioned pattern to smartphone addiction or non-addiction of parents of those kids
Research design
Stage 1: Using a scale I will categorize parents into two groups of Smartphone Non-addicted Parents vs Smartphone Addicted Parents
Stage 2: another scale will measure patterns of kids’ smartphone usage in two occasions:
Occasion 1: typical everyday life (I will repeat asking the same questions during one week-days)
Occasion 2: travel time (I will repeat collecting asking the same questions during a family travel period which can vary from 1 day to 5 days. Please note that 5 days is the average travel time of the families in my target society)
I need your advice on:
1. Regarding the sample size, how many parents should be sampled?
2. I have visualized the structure of the prospective data that will be collected for the above-mentioned research idea in Figure 1 vs Figure 2. Which one is correct?
Warm regards,
Hakimeh
