Sleep is not a solitary activity for the majority of adults, this impacts sleep quality, health, and well-being. Couples experience sleep concordance, or a synchronization of sleep-wake times, which can improve and diminish sleep quality (Gunn et al., 2015). This study explores the association between sleep concordance and sleep quality by examining attachment style as a moderator. Daily sleep diaries were completed by 179 heterosexual couples. Sleep concordance was calculated by dividing total time partners were in bed together by total time at least one partner was in bed each day. Data were analyzed using a multilevel model described by Bolger and Laurenceau (2013). There was a positive association between daily sleep concordance and sleep quality for men. Women with higher secure attachment style scores reported greater sleep quality, and women with higher insecure attachment style scores reported lower sleep quality. Among women with higher secure attachment style scores and lower avoidant attachment style scores there was a negative association between mean sleep concordance and sleep quality. There was no association between sleep concordance and sleep quality for higher anxious attachment scores. Future research is needed to address causal relationships. Findings indicate men and women may experience sleep concordance differently.

The bidirectional link between insufficient sleep and the distress related to a parasomnia known as isolated sleep paralysis (ISP) might lead to chronic health effects. The impact of fear-ridden hallucinations related to this REM sleep disorder can be both distressful and embarrassing for individuals often resulting in a reticence to seek help. This quantitative study was guided by a biopsychosocial approach with an integrated theoretical framework. One aim of the study was to determine if fear parameters of ISP (low and high) differ when considering psychosocial factors and sleep quality, based on the Dysfunctional Beliefs and Attitudes About Sleep Scale, the Social Phobia Inventory, the Locus of Control (LOC) subscales, and the Pittsburg Sleep Quality Inventory. Predictive associations between psychosocial factors and subjective sleep quality (SSQ) were also investigated. Retrospective online data from a sample of 159 participants ages 18 and over were analyzed via MANOVA, multiple regression, and independent samples t-tests. Findings from the MANOVA were significant and showed that participants who experience ISP with more fear scored higher on two measures, external other LOC and social phobia. The MANOVA regarding differences in SSQ in relation to psychosocial variables were not significant, and independent sample t-tests did not differentiate fear parameters for DBAS and SSQ (poor sleep was found for both parameters). Providers of therapeutic treatments should take factors of social phobia and external other LOC into account with regards to poor sleep quality for those distressed by ISP. Sleep quality assessments might benefit those who are afraid to disclose about ISP sleep distress, as long term poor sleep can place some at risk for negative health outcomes.

Miego sutrikimai yra vienas labiausiai paplitusių nūdienos medicininių nusiskundimų. Paskutiniu metu miego medicina domimasi vis labiau, keičiasi gydytojų ir visuomenės supratimas apie miegą, jo sutrikimus, ligas ir negalavimus, susijusius su miegu. Vienas iš svarbesnių ir labai varginančių sutrikimų yra miegas be poilsio jausmo. Mokslininkai iki šiol diskutuoja, kas lemia poilsio jausmą po miego. Pastaruoju metu nemažai dėmesio skiriama miego vientisumo ir suskaldymo reikšmės poilsio jausmui tyrimams. Manoma, kad miego fragmentacija – miego suskaidymas dažnais trumpais nubudimais – mažina jo atstatomąją vertę, ypač smegenims. Pagrindinis darbo tikslas buvo išnagrinėti miego struktūrą ir kokybę per miego ciklus, fazes ir stadijas bei įvertinti miego struktūros ryšį su poilsio jausmu po miego nepriklausomai nuo nemigos tipo. Buvo nagrinėjami trijų tipų – elgesiniai, vegetaciniai ir žieviniai mikro – nubudimai ir jų dinamika nakties metu, skirtinguose miego cikluose ir stadijose. Subjektyviai vertinama miego kokybė buvo analizuojama pasitelkus Pitsburgo miego kokybės indeksą. Darbo rezultatai parodė, kad miego stabilumas nakties pradžioje turi didesnę įtaką subjektyviam miego kokybės jausmui negu miegas nakties pabaigoje. Nubudimų indekso dydžiui reikšmingos įtakos turi miego stadija ir nubudimo tipas, nepriklausomai nuo miego ciklo, o didžiausią įtaką poilsio jausmui turi visų tipų nubudimų, ypač žievinių mikronubudimų, indeksų padidėjimas antroje lėtojo miego stadijoje. / Sleep disorders are one of the most common medical complaints today. There is a growing interest in sleep medicine, attitude of doctors and society is changing and knowledge about sleep and its disorders is increasing. One of the most tedious and understudied sleep problems is non-restorative sleep. Researchers are still debating about what determines persons rest sense after the sleep. A lot of attention recently is paid for sleep integrity and a role of sleep fragmentation for the rest sense. It is thought that sleep fragmentation with short arousals could have effect on the sleeps restorative function. The aim of our study was to analyze sleep structure and sleep quality through sleep cycles, phases and stages and to evaluate structure’s relationship with subjective sense of rest after the sleep without paying attention to the type of insomnia. We have analysed three types of arousals (behavioural, vegetative and microarousals) and their dynamics during the night, in different sleep cycles and stages. Subjective sleep quality was evaluated using the Pittsburgh sleep quality index. Work results showed that for the subjective sense of rest after the sleep it is more important the stability of sleep in the initial than in the last sleep cycles. Sleep stage and arousal type regardless of sleep cycle are significant factors for the arousal index values and that increase of all arousal indices in NREM 2 stage (especially increase of microarousal index) has strongest impact for...
