Looking forward to random slopes and more than two levels in MSEM at last :D

These results imply that researchers should consider assessing quality indicators alongside quantity when measuring mobile media use, unless they are specifically interested in exposure time. The discussion provides suggestions on how to make use of quality indicators in practice.

Mixed-Effects Structural Equation Modeling showed that both indicators of quality were more strongly related to mobile vigilance than duration was. This was not due to the perception of control, which was employed as a control variable.

Using three waves of a longitudinal survey of a representative sample of 1,525 Spanish emerging adults, we examined if duration (screen time) and gratification and situation variety predict mobile vigilance – a cognitive and behavioral connection to the smartphone indicating its relevance in life.

In the paper, we actually compared effects on instant messaging and social media app use for this reason. Social media use was slightly more affected, as it is probably still perceived as less acceptable than instant messaging, which has become a norm.

Don‘t let your ethics committee find out :D

Thanks! Yes, at least according to our results based on data where both event log access and short surveys were employed. If nothing else, it is recommended to collect event log data for more than 5 days and check whether there are systematic changes in use before, just to be on the safe side.

Although the effects were weak to moderate, future research should carefully consider using data before these thresholds when using these methods, especially when they are combined.

Answer: Yes, they do, the results show that providing event log access leads to reductions in smartphone use frequency and duration for five to six days. In contrast, answering short survey prompts increased both for two to three hours.

Better late than never

Pure luck, I found snacks offered on a table next to a session I attended and snuck them in… like a chipmunk
