All general linear mixed models made use of age, intercourse, Bmi, members of the family earnings, competition, and you can physical exercise since covariates, and you will accounted for testing website and you will household members nesting of men and women. We first tested this new matchmaking off son anxiety and you can child despair so you can total EMU, because found inside the Dining table dos. Kid report from weekday 
EMU and you can one another kid and father or mother report out of week-end EMU were significantly with the nervousness periods. Having anxiety, one another child and you may mother or father statement out-of each other weekday and you will week-end EMU had been significantly for the despair. We next questioned if or not often guy otherwise mother claimed EMU proceeded getting with the anxiety once dealing with to have anxiety. Zero EMU scale demonstrated a life threatening experience of stress symptoms when handling to possess anxiety. Every reports regarding EMU stayed significantly linked to anxiety when controlling to have nervousness, besides boy statement of weekday EMU. From note, although of contacts was significant, the result brands was indeed apparently quick.
We next conducted a generalized linear mixed model with all four EMU reports as predictors of anxiety, and the same covariates described above. In this model, parent weekend report of general EMU was a significant independent predictor of anxiety (t =3.43, p =0.001). However, when depression was added as a covariate, none of the EMU measures significantly predicted anxiety. For depression, child weekend EMU report and parent weekend EMU report were each significantly related to depression (t = 2.38, p = 0.017 and t = 3.79, p < 0.001 respectively), while neither weekday EMU report had significant relation to depression. When anxiety was added as a covariate, parent weekend EMU continued to be a significant independent predictor (t = 2.13, p = 0.034).
Sex Distinctions
We analyzed whether sex moderated any of the relationships between EMU report and either anxiety or depression. The only significant interaction with sex was for child report of weekend EMU predicting anxiety (t = ? 3.51, p < .001). Looking at separate mixed models for boys and girls, boys' weekend EMU was significantly associated with anxiety symptoms (t = 4.88, p < .001), but girls' weekend EMU was not (Table 3). For depression, no measures of EMU demonstrated sex differences.
Anxiety and you may Nervousness since the a purpose of EMU
Additionally, to examine perhaps the proportions of children exactly who came across “clinical” cutoffs towards anxiety and stress methods (T scores of 65 otherwise more than) differed as a function of EMU, we presented more analyses having fun with Chi-square tests to look at percentage of children over the logical cutoff to possess depression and you will stress once the a function of level of EMU. The variety of digital news have fun with ranged towards weekdays in the place of the fresh weekend. Thus, to have weekday (each other moms and dad and man account), we grouped EMU because of the 0 to 60 minute (up to step 1 h), sixty so you’re able to 120 min (1 to 2 h), 120 to help you 180 min (two to three h) and greater than 180 min (over step 3 h). Having sunday (both mother and you may man records), i grouped EMU by the 0 so you can 120 minute (as much as 2 h), 120 in order to 240 min (2 to 4 h), 240 so you’re able to 360 min (four to six h) and you can greater than 360 minute (over 6 h). Just like the found from inside the Supplemental Table 3, the fresh new Chi-square data was high each combination of classification out-of EMU report and one another anxiety and nervousness on total shot. On majority from instances, the new portion of pupils over the systematic cutoffs for both stress and you will despair are alongside twice (or maybe more) within lower group of EMU while the higher category of EMU for both man and you will mother or father report as well as each other nervousness and you can anxiety, that have a somewhat linear boost across amounts of EMU. Just like the noted a lot more than, the only real communications which have intercourse and you will EMU i found is to own weekend EMU forecasting anxiety. Because shown during the Extra Dining table 4, to own boys, this new Chi square study is once again tall for each mix of category of EMU declaration and you will each other despair and you can nervousness, again having a close in order to increasing out of percentage of men more than new logical cutoffs regarding the high as opposed to lower EMU explore groups. Because the shown into the Supplemental Dining table 5, for girls, the fresh new activities was comparable getting depression both for mother or father and man reported EMU, which have high Chi Squares both for parent EMU account, however with complete low levels away from despair. Having nervousness, the new habits was in fact alot more adjustable on 2nd higher EMU height appearing increases from inside the proportions of kids more than logical cutoffs for the majority times, however the highest account either shedding off once more. These some other designs having children to possess stress was in fact consistent on the number 1 performance shown throughout the text message.
