“…The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality (Smyth, 2000). The PSQI is widely used in sleep research and measures sleep disturbance and usual sleep habits and has high internal reliability and construct validity (Carpenter & Andrykowski, 1998).…”

Spirituality and gratitude are associated with wellbeing. Few if any studies have examined the role of gratitude in heart failure (HF) patients or whether it is a mechanism through which spirituality may exert its beneficial effects on physical and mental health in this clinical population. This study examined associations bet ween gratitude, spiritual wellbeing, sleep, mood, fatigue, cardiac-specific self-efficacy, and inflammation in 186 men and women with Stage B asymptomatic HF (age 66.5 years ±10). In correlational analysis, gratitude was associated with better sleep (r=-.25, p<0.01), less depressed mood (r=-.41, p<0.01), less fatigue (r=-.46, p<0.01), and better self-efficacy to maintain cardiac function (r=.42, p<0.01). Patients expressing more gratitude also had lower levels of inflammatory biomarkers (r=-.17, p<0.05). We further explored relationships among these variables by examining a putative pathway to determine whether spirituality exerts its beneficial effects through gratitude. We found that gratitude fully mediated the relationship between spiritual wellbeing and sleep quality (z=−2.35, SE=.03, p=.02) and also the relationship between spiritual wellbeing and depressed mood (z=−4.00, SE=.075, p<.001). Gratitude also partially mediated the relationships between spiritual wellbeing and fatigue (z=−3.85, SE=.18, p<.001), and between spiritual wellbeing and self-efficacy (z=2.91, SE=.04, p=.003). In sum, we report that gratitude and spiritual wellbeing are related to better mood and sleep, less fatigue, and more self-efficacy, and that gratitude fully or partially mediates the beneficial effects of spiritual wellbeing on these endpoints. Efforts to increase gratitude may be a treatment for improving wellbeing in HF patients’ lives and be of potential clinical value.

“…Several of these measures have been demonstrated to have robust psychometric properties and have become widely used in both clinical and research settings. The Pittsburg Sleep Quality Index developed in 1989 by Buysse and colleagues [Buysse et al, 1989] has become an important assessment tool which is helpful in measuring temporal changes in sleep quality or sleep disturbance related to various disease states [Baskett et al, 2003;Buysse et al, 1991;Carpenter and Andrykowski, 1998;Doi et al, 2000;Gentili et al, 1995;Petit et al, 2003;Smyth, 1999]. While similarly validated instruments are available for diagnostic assessment [Douglass et al, 1994;Roth et al, 2002;Schramm et al, 1993] as well as follow-up of insomnia populations [Douglass et al, 1994;Moul et al, 2002;Soldatos et al, 2000Soldatos et al, , 2003, their use is not as widespread possibly due to their more recent introduction to the field.…”

Insomnia causes, consequences, and therapeutics: An overview

2003

There is growing interest in insomnia both from the perspective of recent advances in clinical management as well as research aimed at elucidating its pathophysiology. This theoretical overview of insomnia describes the negative impact, etiological considerations, and pharmacological and behavioral treatments for the disorder, with an emphasis on areas receiving increased research attention. Insomnia, the most prevalent sleep disorder, affects 10-15% of the general population. In population-based studies severe insomnia has been shown to last for a median of 4 years. In addition, insomnia has a significant negative impact on an individual's work, physical, and social performance as well as overall quality of life. Furthermore, the economic cost of insomnia related to lost productivity, work-related accidents, absenteeism, and health-care costs are enormous. There is increasing evidence linking the precipitation of insomnia to stress, and converging evidence from cognitive, endocrine, neurological, and behavioral domains provide clear evidence for hyper-arousal in insomnia. However, there remains no consensus regarding the specific etiological mechanisms of this disorder. Although the pathophysiology of primary insomnia remains an enigma, numerous treatments both pharmacological and behavioral have been developed and found to be efficacious in controlled studies. Despite the wide availability of pharmacological treatments and increased knowledge of behavioral interventions, the vast majority of individuals with insomnia do not appear to be receiving adequate treatment. The inadequate treatment of insomnia leads to several important and under-recognized consequences including subsequent development of psychiatric disease and increased substance use.

“…Sleep quality was also assessed at both time-points with the Pittsburgh Sleep Quality Index (PSQI) (Buysee, Reynolds, Monk, & Berman, 1989) which measures quality and patterns of sleep over the past month, with higher scores reflecting poorer sleep quality (Smyth, 1999). Total PSQI has demonstrated construct validity (Jomeen & Martin, 2007) and internal consistency in pregnancy (Jomeen & Martin, 2007;Skouteris, Germano, Wertheim, Paxton, & Milgrom, 2008) and postpartum Total PSQI has obtained a Cronbach's alpha of .83 (Smyth, 1999); current study alpha = .75.…”

Background: Pregnancy has been identified as a risk factor for increasing rates of obesity in women. In recent years, psychological factors have been demonstrated to play a key role in contributing to and maintaining postpartum weight retention (PWR). Objective: The aim of this study was to explore the relationship between psychological distress during late pregnancy and early postpartum, specifically depression, anxiety, stress, and body dissatisfaction, and early PWR. Methods: Pregnant women (N = 227) completed a series of questionnaires at 32 weeks gestation and 3 months postpartum. Results: The most salient predictor of PWR was gestational weight gain (GWG). In a prospective hierarchical regression analysis, only GWG contributed unique prediction of early PWR. In a second hierarchical regression analysis examining cross-sectional relationships with three-month PWR, GWG and early postpartum stress contributed unique variance while the contribution of feelings of fatness approached significance. Conclusions: Given the large association of GWG to early PWR, interventions should focus on the prevention of GWG during pregnancy, as well as screening for body dissatisfaction and stress in the early postpartum.
