This study evaluates transfer from domain-specific, sensorimotor training to cognitive abilities associated with executive function. We examined Individualized Piano Instruction (IPI) as a potential cognitive intervention to mitigate normal age-related cognitive decline in older adults. Thirty-one musically naïve community-dwelling older adults (ages 60–85) were randomly assigned to either the experimental group (n = 16) or control group (n = 15). Neuropsychological assessments were administered at three time points: pre-training, following six months of intervention, and following a three-month delay. The experimental group significantly improved performance on the Trail Making Test and Digit Symbol measures as compared to healthy controls. Results of this study suggest that IPI may serve as an effective cognitive intervention for age-related cognitive decline.

Summary: The main objective of the present study was to examine daily associations (intraindividual variability or IIV) between sleep and affect in older adults. Greater understanding of these associations is important, because both sleep and affect represent modifiable behaviors that can have a major influence on older adults’ health and well‐being. We collected sleep diaries, actigraphy, and affect data concurrently for 14 days in 103 community‐dwelling older adults. Multilevel modeling was used to assess the sleep–affect relationship at both the group (between‐persons) and individual (within‐person or IIV) levels. We hypothesized that nights characterized by better sleep would be associated with days characterized by higher positive affect and lower negative affect, and that the inverse would be true for poor sleep. Daily associations were found between affect and subjective sleep, only and were in the hypothesized direction. Specifically, nights with greater reported awake time or lower sleep quality ratings were associated with days characterized by less positive affect and more negative affect. Gender was not a significant main effect in the present study, despite previous research suggesting gender differences in the sleep–affect relationship. The fact that self‐ratings of sleep emerged as the best predictors of affect may suggest that perceived sleep is a particularly important predictor. Finally, our results suggest exploration of affect as a potential intervention target in late‐life insomnia is warranted.

Sleep disturbances and increased negative mood are common among chronic pain patients. Research suggests that sleep disruption can contribute to increased pain; however, the role of negative mood in this relationship is unclear. The present study investigated the relationship among sleep disturbance, negative mood, and pain within a large sample of chronic pain patients. It was hypothesized that negative mood would mediate the relationship between sleep and pain. In all, 292 chronic pain patients (116 facial pain, 55 back pain, 121 fibromyalgia) between 18 and 65 years of age (M=46.67) were recruited from 3 chronic pain clinics at a large tertiary care hospital. Patients completed validated measures of pain, negative mood, and sleep during a routine clinical assessment. Structural equation modeling examined the relationship between sleep, negative mood, and pain. All 3 groups of patients reported sleep disturbances, with these being highest among back pain and fibromyalgia patients. Structural equation modeling analyses revealed a significant direct relationship between poor sleep and pain, and further demonstrated that negative mood mediated the relationship between poor sleep and pain in this sample of chronic pain patients. These findings suggest that addressing negative mood directly, or by addressing sleep disturbances in chronic pain patients, may have a beneficial impact on patients' pain. As sleep disturbance may be causing negative mood, treating the sleep disturbance may also be beneficial among chronic pain patients. Negative mood may perpetuate the impact of sleep disturbances on pain, possibly through increased arousal or disruptions in diurnal patterns.

Summary: Exercise behaviour and sleep are both important health indicators that demonstrate significant decreases with age, and remain modifiable well into later life. The current investigation examined both the chronic and acute relationships between exercise behaviour and self‐reported sleep in older adults through a secondary analysis of a clinical trial of a lifestyle intervention. Seventy‐nine community‐dwelling, initially sedentary, older adults (mean age = 63.58 years, SD = 8.66 years) completed daily home‐based assessments of exercise behaviour and sleep using daily diary methodology. Assessments were collected weekly and continued for 18 consecutive weeks. Multilevel models revealed a small positive chronic (between‐person mean‐level) association between exercise and wake time after sleep onset, and a small positive acute (within‐person, day‐to‐day) association between exercise and general sleep quality rating. The within‐person exercise and general sleep quality rating relationship was found to be reciprocal (i.e. sleep quality also predicted subsequent exercise behaviour). As such, it appears exercise and sleep are dynamically related in older adults. Efforts to intervene on either sleep or exercise in late‐life would be wise to take the other into account. Light exposure, temperature regulation and mood may be potential mechanisms of action through which exercise can impact sleep in older adults.

We examined sleep complaints, subjective and objective sleep patterns, health, psychological adjustment, and daytime functioning in 103 community-dwelling older adults to identify factors associated with sleep complaints. We collected 2 weeks of sleep diaries and actigraphy. Only health distinguished complaining from noncomplaining sleepers. Noncomplaining good sleepers had poorer objective sleep quantity than complaining poor sleepers. Actigraphy distinguished noncomplaining good and complaining poor sleepers only. Subjective and objective sleep quantities were related for noncomplainers only; this relationship was stronger for women. Implications include a need for research exploring: 1. sleep complaints, sleep perceptions, and health; 2. interventions focusing on older individuals with insomnia secondary to/comorbid with poor health; 3. gender differences in subjective sleep estimates and in “single-shot” versus longitudinal sleep measures.
