4-3-2. Effects on SH2 subscales
ADVERSE EFFECTS, ADVERSE EFFECT
To identify which subitems of SH2 improved through the intervention, we further estimate A statistically significant effect was confirmed for There are some other notable findings in the table. First, from the results in column 7, an increase in the number of days spent working from home may have caused the participants to experience more “trouble sleeping through the night and waking up in the middle of the night.” Telework may have an adverse effect on sleep, such as nocturnal awakening, potentially due to changes in work schedule, such as working until just before going to bed or waking up later. However, no adverse effects other than nocturnal awakening were detected for telework; thus, any adverse effect it has on sleep may be limited. Second, those who had an increase in workload may have experienced a decrease in “falling asleep fast enough to lose consciousness within five minutes” (column 10). Third, for those who were promoted during the RCT implementation period, “feeling sleepy” (column 4) was statistically negative and significant, while “waking up more than an hour early and having trouble going back to sleep” (column 6) was statistically positive and significant. This result can be interpreted as suggesting that immediately after a promotion, workers are more likely to feel nervous and excited by the new tasks they are given and are more likely to have trouble sleeping. No effects were detected for items other than these two, however.
