“…In the present study, the analytic sample comprises participants from this RCT who consistently wore the activity monitor for at least 100 days and nights (~ 3 months) with less than 5% of missing observations for both behaviors (data collection occurred in the first months of the RCT). This cut-off ensures sufficient statistical power at the individual level to test the person-specific associations (i.e., build a statistical model for each participant separately; Ariens et al, 2020 ).…”

The objective of the present study was to estimate whether physical activity on one day was associated with both sleep quality and quantity the following night and to examine to what extent sleep on one night was associated with physical activity the next day. We collected data from 33 young adults who were overweight or obese and consistently wore a Fitbit Charge 3. A total of 7094 days and nights were analyzed. Person-specific models were conducted to test the bi-directional associations for each participant separately. Results suggest an absence of association between steps and sleep efficiency in the two directions. More heterogeneous results were observed for the association between steps and total sleep time, with 19 participants (58%) showing a negative association between total sleep time and next day steps, and 9 (27%) showing a negative association between steps and next day total sleep time. Taken together, these results suggest a potential conflicting association between total sleep time and physical activity for some participants.

“…We will provide a systematic review of studies in which within-person relationships between pain and affect have been examined using daily diary or ecological momentary assessment (EMA) approaches that allow for sufficient intensive longitudinal data (ILD) to examine within-person relationships over time [23]. Extant reviews of the literature suggest that gathering ILD from patients with chronic pain is highly feasible [24,25].…”

Objective: Chronic pain is conceptualized as a biopsychosocial phenomenon that involves both physical and emotional processes. The vast majority of research regarding these facets of chronic pain characterizes differences between individuals. In this review, we describe problems with assuming that differences between persons accurately characterize within-person processes. We also provide a systematic review of studies that have examined within-person relationships between pain and affect among individuals with chronic pain.Method: Articles published by December 2020 that pertained to within-person assessment of pain and emotion, affect, or mood were identified. Data regarding study design, adherence, and concurrent and prospective relationships among pain and affect variables were extracted and summarized.Results: Of 611 abstracts, 55 studies met inclusion criteria. Results suggest that individuals with chronic pain tend to experience increased negative affect and decreased positive affect when experiencing more severe pain (rpooled = .18 and -.19, respectively). However, the size of these effects appeared smaller than between-person associations, and there was evidence of significant variability between individuals. Examination of predictive relationships between pain and affect largely suggested the tendency of symptoms to predict themselves, rather than pain predicting affect or vice versa.Conclusions: Consistent with group-level relationships, experiencing more severe pain relative to an individual's average seems to be associated with more negative affect and less positive affect.However, individuals vary in the size and even direction of these effects. More research is necessary to understand the implications of such variability for the assessment and treatment of chronic pain.

The objective of the present study was to estimate whether physical activity (i.e., step counts) on one day was associated with both sleep quality (i.e., sleep efficiency) and quantity (i.e., total sleep time) the following night and to examine to what extent sleep on one night was associated with physical activity the next day. We collected data continuously with a Fitbit Charge 3 among 33 young adults with overweight and obesity participating to a weight management program. A total of 7094 days and nights were analyzed (215 days on average per participants). Person-specific models (i.e., participants were not pooled together) were conducted to test the bi-directional associations for each participant separately. Results from linear regressions and Generalized Additive Models (GAMs) were compared to account for potential non-linearities in associations. Results suggest an absence of association between steps and sleep efficiency in the two directions for most participants [i.e., these associations were not significant for 31 (94%) and 32 (97%) of the participants]. More heterogeneous results were observed for the association between steps and total sleep time, with 19 participants (58%) showing a negative association between total sleep time and next day steps, and 9 (27%) showing a negative association between steps and next day total sleep time (results of the linear regressions). Taken together, these results suggest a potential conflicting association between total sleep time and physical activity in the daily lives of young adults with overweight and obesity.
