Whilst many studies have focused on the total phone usage and sleep problems, not many studies have investigated the contribution of an app category to sleep problems. Therefore, this study aims to examine the relationship between different smartphone app categories and sleep duration, using objective data collection methods. Data from a different project was used, which tracked 88 participants aged 16 to 45 over 14 nights, gathering phone usage data and sleep data using objective measures. Phone data was gathered from 3 hours before sleep onset. Following exclusion criteria, 38 participants remained, which resulted in 532 data entries for analysis. The results from the first analysis indicated that the app category ‘Social’ had a significant positive influence on sleep duration (Beta = .12, p =.01), suggesting a possible positive relationship between social media usage and sleep duration. The second analysis, which combined the app categories ‘Social’ and ‘Communication’ into a new variable, labeled ‘SocCom’, also revealed a significant positive relationship with sleep duration (Beta = .14, p = .002). The third analysis, which examined the total time spent on a phone and sleep duration found a positive relationship (r = .09, p = .04), indicating that more phone usage was associated with longer sleep duration. These findings contradict the conventional ideas that increased phone usage before sleep leads to less sleep duration. However, due to limitations of this study, the results cannot be interpreted as causal relationships, as many unknown variables might influence the results. Further studies should explore this topic further, using a more controlled study design.Show less

It is investigated whether anxiety complaints have a mediating effect, and whether burnout has a moderating effect. An association has been found in the literature for the relationship between role conflict and anxiety symptoms, as well as for anxiety symptoms and reduced sleep quality. In addition, it turned out that burnout has an effect on these three variables. Four online questionnaires were used for this study, which were completed over a period of three weeks. The results of this study showed no significant indirect effect, also burnout was not a significant moderator. However, a non-significant association was found between decreased sleep quality and role conflict. It is recommended that more research be done on this in the futureShow less

Studies have revealed that temperament might be a predictor of sleep disturbances in children. The aim of the current study was to examine the association between different temperament traits and sleep disturbances, sleep onset latency, sleep duration and subjective sleep quality in children. Participants were 113 children, aged 9 – 11 years (M = 10.47 years; SD = .72). Parents kept track of a sleep diary and both parents and children completed several questionnaires, regarding sleep and temperament. Significant associations were found between the different sleep disturbances and effortful control, high intensity pleasure/surgency, frustration, affiliation, and fear. Sleep duration was related to affiliation and fear. Subjective sleep quality was associated with affiliation and shyness. The current study provides evidence for the association between and sleep and temperament.Show less
