The primary aim of this study was to examine the pattern of associations among PD patient and caregiver sleep problems, caregiver burden, and caregiver life satisfaction. A secondary aim was to assess whether the pattern of associations differed between Mexican and U.S. caregivers. Analyses were performed on data obtained from 253 caregivers (M age = 59.92). A composite score was produced for caregiver and patient sleep problems. The Zarit Burden Interview and Satisfaction with Life Scale measured caregiver burden and life satisfaction, respectively. A structural equation model with an invariance design was developed to examine and compare the pattern of associations. The model was generally invariant across U.S. and Mexican caregivers. Three significant indirect effects were found: caregiver sleep problems were negatively associated with life satisfaction via caregiver burden (p = 0.003); PD patient sleep problems were positively related to caregiver burden via caregiver sleep problems (p = 0.005) and life satisfaction via caregiver burden and caregiver sleep problems (p = 0.002). PD patient sleep problems were associated with caregiver sleep problems, leading to increased burden in caregivers and poorer life satisfaction. The findings highlight a potential opportunity for empirically supported sleep interventions. Parkinson's disease is a progressive neurological condition that impacts patient and caregiver quality of life. Patient sleep problems contribute to greater caregiver burden, sleep problems, and reduced life satisfaction. The findings suggest patient and caregiver sleep may be a worthwhile target for intervention in order to reduce risk of caregiver burden and improve life satisfaction. [ABSTRACT FROM AUTHOR]

Objectives: Older adults experience age‐related cognitive declines and often feel as if the severity of these declines is out of their control. Recent research suggests, though, that control beliefs may be related to less age‐related declines. The aim of the current study was to investigate cognitive domain‐specific control beliefs and the link between those cognitive control beliefs and cognitive functioning among a nationwide sample of adults (N = 3,670), as well as to explore whether cognitive control beliefs moderated the relationship between age and cognitive functioning. Method: The aims were addressed using data from the national Midlife in the United States study (MIDUS II). Cognitive functioning was assessed using the Brief Test of Adult Cognition by Telephone (BTACT), and cognitive control beliefs were assessed with the Personality in Intellectual Aging Contexts (PIC) Inventory Control Scales. Results: Regression analyses revealed that adults with higher control beliefs demonstrated better cognitive functioning. Moderation analyses indicated cognitive control beliefs moderated the relationship between age and executive functioning, but not the association between age and episodic memory. Conclusion: Results suggested that the relationship between age and executive functioning was weaker at high levels of cognitive control beliefs. Future research should establish the directionality of the effect between cognitive control beliefs and cognition and investigate the association between control beliefs and cognition in samples at higher risk for substantial cognitive decline, including the oldest‐old.

Objective/Background: Sleep health is a multidimensional construct of sleep and wakefulness that operationalizes optimal sleep as more than the absence disease. Despite its importance to public health promotion efforts, empirical research examining sleep health is currently limited, possibly due to the lack of empirically validated measures. Therefore, the purpose of the current study was to evaluate the psychometric properties of a previously proposed six-item sleep health scale (RU- SATED). Participants: A sample of 3,401 adults (Mean Age = 42.77, 47.8% female) completed an online survey of sleep and health. Methods: Participants completed the RU-SATED scale, as well as other sleep-related measures including the Insomnia Severity Index (ISI) and the Sleep Self-Efficacy Scale (SSE). Results: An exploratory factor analysis (EFA) revealed a two-factor structure. A confirmatory factor analysis (CFA) using this two-factor structure demonstrated adequate to good model fit indices (X2 = 45.96, df = 8, p <.01; RMSEA =.04; CFI =.98; NFI =.98; TLI =.97). Cronbach's α was.64 and the average interitem correlation was.22. RU-SATED was negatively associated with insomnia severity and positively associated with both self-reported sleep and sleep self-efficacy. Conclusions: RU-SATED appears to be a valid instrument for the assessment of sleep health among adults that is related to, but distinct from, other established sleep constructs. Future research may benefit from examining the test–retest reliability of the measure and assessing the predictive validity of sleep health as it relates to health-related outcomes.

Objectives: The goal of the study was to examine the influence of sleep efficiency on the relationship between anxiety and executive functions. Method: Secondary data analyses of 82 community-dwelling middle-aged and older adults were performed (M age = 63.00, SD = 8.64). Anxiety was measured using the trait anxiety subscale of the State-Trait Anxiety Inventory. Sleep efficiency was measured using one-week of sleep diary data. Two executive functions, cognitive flexibility and inductive reasoning, were measured using the Trail-Making Test and Letter Series task, respectively. SPSS PROCESS macro software version 2 was used to assess the moderating role of sleep efficiency in the relationship between anxiety and executive functions. Results: Sleep significantly moderated the relationship between anxiety and inductive reasoning. Among middle-aged and older adults with high anxiety, those with good sleep efficiency displayed significantly better inductive reasoning than those with poor sleep efficiency after controlling for age, gender, and education (ΔR2 =.05, p =.017). Sleep efficiency did not significantly moderate the relationship between anxiety and cognitive flexibility. Conclusion: Sleep efficiency weakened the association between anxiety and inductive reasoning in middle-aged and older adults. Evidence from the study suggests better sleep may limit the negative effects of anxiety on executive functions in mid-to-late life. Further research is needed to elucidate the impact of anxiety and sleep on executive functions in clinical populations with anxiety. [ABSTRACT FROM AUTHOR]

Objective. Cigarette smokers seeking treatment for chronic pain have higher rates of opioid use than nonsmokers. This study aims to examine whether veterans of Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND) who smoke are more likely to receive an opioid prescription than nonsmokers, adjusting for current pain intensity. Design. Cross-sectional analysis of a cohort study of OEF/OIF/OND veterans who had at least one visit to a Veterans Health Administration primary care clinic between 2001 and 2012. Methods. Smoking status was defined as current, former, and never. Current pain intensity (+/- 30 days of smoking status), based on the 0-10 numeric rating scale, was categorized as no pain/mild (0-3) and moderate/severe (4-10). Opioid receipt was defined as at least one prescription filled +/- 30 days of smoking status. Results. We identified 406,954 OEF/OIF/OND veterans: The mean age was 30 years, 12.5% were women (n = 50,988), 66.3% reported no pain or mild pain intensity, 33.7% reported moderate or severe pain intensity, 37.2% were current smokers, and 16% were former smokers. Overall, 33,960 (8.3%) veterans received one or more opioid prescription. Current smoking (odds ratio [OR] = 1.56, 95% confidence interval [CI] = 1.52-1.61) and former smoking (OR = 1.27, 95% CI = 1.22-1.32) were associated with a higher likelihood of receipt of an opioid prescription compared with never smoking, after controlling for other covariates. Conclusions. We found an association between smoking status and receipt of an opioid prescription. The effect was stronger for current smokers than former smokers, highlighting the need to determine whether smoking cessation is associated with a reduction in opioid use among veterans.

Summary: Poor sleep and chronic pain are known to be interrelated, but the influence of negative and positive affect on this relationship is not fully understood. The present study sought to examine whether negative and positive affect mediate the relationship between sleep and pain interference. Secondary data analysis from Midlife in the United States (MIDUS‐III) was used to examine 948 individuals with chronic pain (mean age = 64.73 years). Sleep disturbance was conceptualized as the sum of self‐reported difficulty with sleep‐onset latency, wake after sleep onset, early morning awakening and daytime sleepiness, and total sleep time was assessed via self‐reported sleep duration. Pain interference was operationalized as the sum of pain‐related interference with general activity, relationships and enjoyment of life. Finally, items from the Positive and Negative Affect Schedule were used to measure affect. Mediation analyses revealed that sleep disturbance indirectly predicted pain interference via both negative affect (β = 0.15, confidence interval: 0.10, 0.21) and positive affect (β = 0.18, confidence interval: 0.12, 0.25). Similarly, negative (β = −0.003, confidence interval: −0.01, −0.001) and positive affect (β = −0.003, confidence interval: −0.01, −0.001) also mediated the effect between total sleep time and pain interference. This study highlights the unique role of negative and positive affect on pain interference for individuals with chronic pain in mid‐ to late‐life. Additionally, findings suggest that holistic treatment approaches, which assess both sleep and affect in the context of chronic pain, may be beneficial. [ABSTRACT FROM AUTHOR]
