Increasing evidence indicates that, in addition to poverty, maternal depression, and other well-established factors, unpredictability of maternal and environmental signals early in life influences trajectories of brain development, determining risk for subsequent mental illness. However, whereas most risk factors for later vulnerability to mental illness are readily measured using existing, clinically available tools, there are no similar measures for assessing early-life unpredictability. Here we validate the Questionnaire of Unpredictability in Childhood (QUIC) and examine its associations with mental health in the context of other indicators of childhood adversity (e.g., traumatic life events, socioeconomic status, and parenting quality). The QUIC was …

Prompts To Increase Physical Activity At Points-Of-Choice Between Stairs And Escalators: What About Escalator Climbers?, John Belletierre, Ben Nguyen, Sandy Liles, Vincent Berardi, Marc A. Adams, Paddy Dempsey, Yael Benporat, Jacqueline Kerr, Andrea Z. Lacroix, Melbourne Hovell

Since 1980, many studies have evaluated whether stair-use prompts increased physical activity by quantifying changes in stair use. To more completely evaluate changes in physical activity, this study addressed the often-overlooked assessment of climbing up escalators by evaluating the degree to which stair-use sign prompts increased active ascent—defined as stair use or escalator climbing. Over 5 months, at an airport stairs/escalator point of choice, we video-recorded passersby (N = 13,544) who ascended either stairs or escalators, on 10 days with signs and 10 days without signs. Ascenders using the stairs, standing on the escalator, and climbing the escalator were …

A Markov Approach For Increasing Precision In The Assessment Of Data-Intensive Behavioral Interventions, Vincent Berardi, Ricardo Carretero-González, John Belletierre, Marc A. Adams, Suzanne C. Hughes, Melbourne Hovell

Psychology Faculty Articles and Research

Health interventions using real-time sensing technology are characterized by intensive longitudinal data, which has the potential to enable nuanced evaluations of individuals’ responses to treatment. Existing analytic tools were not developed to capitalize on this opportunity as they typically focus on first-order findings such as changes in the level and/or slope of outcome variables over different intervention phases. This paper introduces an exploratory, Markov-based empirical transition method that offers a more comprehensive assessment of behavioral responses when intensive longitudinal data are available. The procedure projects a univariate time-series into discrete states and empirically determines the probability of transitioning from one …

Psychological Well-Being And Restorative Biological Processes: Hdl-C In Older English Adults, Jackie Soo, Laura D. Kubzansky, Ying Chen, Emily S. Zevon, Julia K. Boehm

Psychology Faculty Articles and Research

Rationale

Psychological well-being is associated with better cardiovascular health, but the underlying mechanisms are unclear.

Objective

This study investigates one possible mechanism by examining psychological well-being's prospective association with lipid levels, focusing on high-density lipoprotein cholesterol (HDL-C).

Methods

Participants were 4757 healthy men and women ages ≥50 from the English Longitudinal Study of Ageing with clinical data from three times, three to five years apart. Psychological well-being was assessed at baseline using the Control, Autonomy, Satisfaction, and Pleasure scale; HDL-C, triglycerides, and total cholesterol were assayed from blood samples. Descriptive statistics and linear mixed models were used to examine associations …
