Objective It is known that osteoarthritis (OA) increases risk of sleep disturbance, and that both pain and sleep problems may trigger functional disability and depression. However, studies examining all four variables simultaneously are rare. This research therefore examined cross-sectional and longitudinal associations of self-reported sleep disturbance with OA-related pain and disability, and depressive symptoms. Methods At baseline, 367 persons with physician-diagnosed knee OA reported sleep disturbances, pain, functional limitations, and depressive symptoms. All measures were repeated a year later (N = 288). Baseline analyses examined the independent and interactive associations of sleep disturbance with pain, disability and depression, net of demographics and general health. Longitudinal analyses used baseline sleep disturbance to predict one-year change in pain, disability and depression. Results At baseline, sleep was independently associated with pain and depression, but not disability. The sleep-pain relationship was mediated by depressive symptoms; sleep interacted with pain to exacerbate depression among persons with high levels of pain. Baseline sleep disturbance predicted increased depression and disability, but not pain, at follow-up. Conclusions These data confirm known cross-sectional relationships of sleep disturbance with pain and depression, and provide new insights on longitudinal associations among those variables. Depression appears to play a strong role in the sleep-pain linkage, particularly where pain is severe. The unique predictive role of sleep in progression of disability requires further study, but may be an important point of intervention to prevent OA-related functional decline among persons whose sleep is disrupted by OA pain.

Light is considered the dominant environmental cue, or zeitgeber, influencing the sleep-wake cycle. Despite recognizing the importance of light for our well-being, less is known about the specific conditions under which light is optimally associated with better sleep. Therefore, a systematic review was conducted to examine the association between the amount and timing of light exposure in relation to sleep outcomes in healthy, community-dwelling adults. A systematic search was conducted of four databases from database inception to June 2016. In total, 45 studies met the review eligibility criteria with generally high study quality excepting for the specification of eligibility criteria and the justification of sample size. The majority of studies involved experimental manipulation of light (n=32) vs observational designs (n=13). Broad trends emerged suggesting that (1) bright light (>1000 lux) has positive implications for objectively assessed sleep outcomes compared to dim (<100 lux) and moderate light (100-1000 lux) and (2) bright light (>1000 lux) has positive implications for subjectively assessed sleep outcomes compared to moderate light (100-1000 lux). Effects due to the amount of light are moderated by the timing of light exposure such that, for objectively assessed sleep outcomes, brighter morning and evening light exposure are consistent with a shift in the timing of the sleep period to earlier and later in the * Corresponding author. ndautovich@vcu.edu.

Objective Sleep and pain-related experiences are consistently associated, but the pathways linking these experiences are not well understood. We evaluated whether pain catastrophizing and arthritis self-efficacy mediate the association between sleep disturbance and osteoarthritis (OA) symptom severity in patients with knee OA. Methods We analyzed cross-sectional baseline data collected from Veterans Affairs (VA) patients enrolled in a clinical trial examining the effectiveness of a positive psychology intervention in managing pain from knee OA. Participants indicated how often in the past two weeks they were bothered by trouble falling asleep, staying asleep, or sleeping too much. We used validated scales to assess the primary outcome (OA symptom severity) and potential mediators (arthritis self-efficacy and pain catastrophizing). To test the proposed mediation model, we used parallel multiple mediation analyses with bootstrapping, controlling for sociodemographic and clinical characteristics with bivariate associations with OA symptom severity. Results The sample included 517 patients (Mage = 64 years, 72.9% male, 52.2% African American). On average, participants reported experiencing sleep disturbance at least several days in the past two weeks (M = 1.41, SD = 1.18) and reported moderate OA symptom severity (M = 48.22, SD = 16.36). More frequent sleep disturbance was associated with higher OA symptom severity directly (b = 3.08, P &lt;0.001) and indirectly, through higher pain catastrophizing (b = 0.60, 95% confidence interval [CI] = 0.20 to 1.11) and lower arthritis self-efficacy (b = 0.84, 95% CI = 0.42 to 1.42). Conclusions Pain catastrophizing and arthritis self-efficacy partially mediated the association between sleep disturbance and OA symptom severity. Behavioral interventions that address pain catastrophizing and/or self-efficacy may buffer the association between sleep disturbance and OA symptom severity.

The objective was to examine insomnia and insomnia-related care within a regional network of Department of Veterans Affairs (VA) facilities since the VA roll-out of cognitive behavioral therapy for insomnia (CBT-I) in 2011. A retrospective analysis of VA electronic health records (EHR) data from 2011 to 2019 was conducted. The annual and overall prevalence of four insomnia indicators was measured: diagnoses, medications, consultations for assessment/treatment, and participation in CBT-I. Also examined were sociodemographic and clinical differences among veterans with and without an insomnia indicator, as well as differences among the four individual insomnia indicators. The sample included 439,887 veterans, with 17% identified by one of the four indicators; medications was most common (15%), followed by diagnoses (6%), consults (1.5%), and CBT-I (0.6%). Trends over time included increasing yearly rates for diagnoses, consults, and CBT-I, and decreasing rates for medications. Significant differences were identified between the sociodemographic and clinical variables across indicators. An evaluation of a large sample of veterans identified that prescription sleep medications remain the best way to identify veterans with insomnia. Furthermore, insomnia continues to be under-diagnosed, per VA EHR data, which may have implications for treatment consistent with clinical practice guidelines and may negatively impact veteran health.

Objective: Using the framework of Social Cognitive Career Theory, this study aimed to ascertain attitudes and perceptions of geropsychology career paths, given the present notable geriatric workforce shortage. Methods: An online survey was developed iteratively and disseminated through various modalities (i.e., internet, email, word-of-mouth). Participants included 28 predoctoral and 76 professional geropsychologists (N = 107; age M = 39.18, SD = 12.05). The sample was largely female (72%), non-Hispanic White (89%), and has or was working towards their PhD (82%). Results: Results delineate attractive and unattractive aspects of common career options (academic, clinical Veterans Affairs [VA], clinical non-VA), and assessed the hypothetical proclivity and feasibility of switching between academic and clinically focused careers. The results found gender (women vs. men) and career stages (predoctoral vs.

The main objective of the present study was to examine the potential buffering effect of regularity of the duration of time spent on daily activities in the association between perceived control and affect in communitydwelling adults. The sample for the current study was derived from the Midlife in the United States longitudinal follow-up study, MIDUS-II. Findings corroborated the association between a general sense of perceived control and positive and negative affect. Further, daily regularity was found to moderate the relationships of perceived control and both positive and negative affect. In each case, the findings suggest that individuals who scored lower on perceived control measures were more likely to have better affective outcomes when they demonstrated greater regularity in daily activities. The findings imply the relevance of regularity to affective experiences.

Intraindividual variability is an often understudied aspect of health outcomes research that may provide additional, complementary information to average values. The current paper aims to further our understanding of intraindividual variability in health research by presenting the results of a daily diary study of sleep and pre-sleep arousal. Pre-sleep arousal is often implicated in poor sleep outcomes, although the arousal–sleep association is not uniform across age groups. The examination of intraindividual variability in different age groups may provide a more complete understanding of these constructs, which, in turn, can inform future research. The overall objectives of the current study are to quantify the amount of intraindividual variability in pre-sleep arousal and sleep and to examine age differences in this variability. A sample of older (n=50) and younger (n=50) adults recruited from North Central Florida and online completed 14-consecutive-day diaries assessing pre-sleep arousal and sleep outcomes. Significant age differences were found for sleep and pre-sleep arousal; older adults displayed poorer, more variable sleep for the majority of sleep outcomes, and higher levels of pre-sleep arousal than younger adults. The high amount of intraindividual variability has implications for the assessment of pre-sleep arousal and sleep across age groups.
