An Exploratory Analysis of Accelerometer-Measured Physical Activity and Emotional Functioning in Patients With Chronic Pain.

BACKGROUND: Physical activity (PA) can benefit pain and emotional functioning for patients with chronic pain. However, associations between different intensities of PA (moderate-to-vigorous PA, light PA, and sedentary behavior), pain, and emotional functioning are not well understood in patients with chronic pain. OBJECTIVE: The goals of this study were to (1) describe PA patterns of adult patients with chronic pain using accelerometers and (2) explore preliminary associations between PA intensities, pain, and emotional functioning. METHODS: Thirteen patients with chronic pain completed self-report measures of pain, cognitive and emotional reactions to pain, depression and anxiety, and wore ActiGraph accelerometers for 1 week before participating in a pilot mind-body PA intervention. RESULTS: Sedentary behavior and light activity were strongly inversely correlated (r = -0.93, P < 0.01). Greater sedentary behavior was associated with lower pain during activity (r = -0.55, P = 0.05), and greater light activity was correlated with higher pain during activity (r = 0.63, P = 0.02) and pain at rest (r = 0.54, P = 0.06). However, greater moderate-to-vigorous PA was correlated with lower pain at rest (r = -0.66, P = 0.01), pain catastrophizing (r = -0.53, P = 0.06), depression (r = -0.44, P = 0.14), and anxiety (r = -0.57, P = 0.04). CONCLUSIONS: Objective accelerometer-measured PA has the potential to reveal differential associations between PA intensities, pain, and emotional functioning. Findings here suggest preliminary recommendations to focus on interconnections between moderate-to-vigorous PA, pain at rest, pain catastrophizing, anxiety, and depression for patients with chronic pain.

Assessing within- and between-family variations in an expanded measure of childhood adversity.

Previous measures of childhood adversity have enabled the identification of powerful links with later-life wellbeing. The challenge for the next generation of childhood adversity assessment is to better characterize those links through comprehensive, fine-grained measurement strategies. The expanded, retrospective measure of childhood adversity presented here leveraged analytic and theoretical advances to examine multiple domains of childhood adversity at both the microlevel of siblings and the macrolevel of families. Despite the fact that childhood adversity most often occurs in the context of families, there is a dearth of studies that have validated childhood adversity measures on multiple members of the same families. Multilevel psychometric analyses of this childhood adversity measure administered to 1,194 siblings in 500 families indicated that the additional categories of childhood adversity were widely endorsed, and increased understanding of the sources and sequalae of childhood adversity when partitioned into within- and between-family levels. For example, multilevel confirmatory factor analyses (MCFAs) indicated that financial stress, unsafe neighborhood, and parental unemployment were often experienced similarly by siblings in the same families and stemmed primarily from family wide (between-family) sources. On the other hand, being bullied and school stressors were often experienced differently by siblings and derived primarily from individual (within-family) processes. Multilevel structural equation modeling (MSEM) further illuminated differential criterion validity correlations between these categories of childhood adversity with midlife psychological, social, and physical health. Expanded, multidomain, and multilevel measures of childhood adversity appear to hold promise for identifying layered causes and consequences of adverse childhood experiences.

Thriving in midlife: The roles of childhood nurturance and adult defense mechanisms.

The current study examined whether reliance on more adaptive defense mechanisms throughout early adulthood may help explain previously documented relationships between childhood nurturance and better midlife functioning. Utilizing a unique longitudinal study, data were from age 18 through midlife (age 63) on 135 males. Childhood nurturance was assessed upon study entry and defense mechanism usage was assessed throughout earlier adulthood. Percentage of 'engaging' (more adaptive) vs. 'avoidant' (less adaptive) defenses mediated the relationship between childhood nurturance and 3 midlife outcomes: participants' relationship quality with their children, marriage stability, and maximum earned income. Results suggest that greater childhood nurturance relates to more adaptive defensive styles in early adulthood, which is then associated with healthier midlife functioning at work and in relationships.
