“…Thirty‐three papers were identified that used sensors to measure physical activity levels and energy expenditure (see Table 1). The majority of studies used accelerometers to measure physical activity (Alberti et al, 2013; Belak et al, 2017; Bezzina et al, 2019; Bratland‐Sanda et al, 2011, 2012; Bratland‐Sanda, Sundgot‐Borgen, Ro, et al, 2010a; Bratland‐Sanda, Sundgot‐Borgen, Ro, et al, 2010b; Bratland‐Sanda, Sundgot‐Borgen, Rosenvinge, et al, 2010; Carrera et al, 2012; Duriez, Guy‐Rubin, et al, 2021; El Ghoch et al, 2013, 2016; Grosser et al, 2020; Hofmann et al, 2017; Holtkamp et al, 2006; Kemmer et al, 2020; Keyes et al, 2015; Klein et al, 2007; Kolar et al, 2020; Lampe et al, 2021; Langlet et al, 2021; Lehmann et al, 2018; Martinez‐Sanchez et al, 2020; Mathisen, Bratland‐Sanda, et al, 2018; Mathisen, Rosenvinge, et al, 2018; McDuffie, 1998; Sauchelli et al, 2015; Stengel et al, 2017; van Elburg et al, 2007; Wons et al, 2021; Zeeck et al, 2020). Other sensors utilized include pedometers (Blinder et al, 1970; Crandall, 2004), multi‐sensor full‐body systems including the Intelligent Device for Energy Expenditure and Activity and the Tracmor physical activity sensor system (Bouten et al, 1996; Gianini et al, 2016; Harris et al, 2008), and indirect calorimeter (Bouten et al, 1996; Harris et al, 2008).…”

Objective Sensor technologies offer exciting potential to objectively measure psychopathological correlates of eating pathology and eating disorder (ED) research utilizing sensors has rapidly proliferated in the past several years. The aims of the present review are: (1) characterize the types of sensors that have been utilized in ED research, (2) identify the psychopathological factors relevant to EDs that have been assessed using sensors, (3) describe the data supporting the validity and reliability of these sensors, (4) discuss limitations associated with these sensors, and (5) identify gaps that persist within the ED literature with regard to use of sensor technologies. Method A systematic search was conducted of PubMed, PsycINFO, Web of Science, ProQuest, and “gray” literature sources. Eligible publications were empirical studies that utilized sensors to measure at least one psychological variable among clinical ED populations. Results Sensors have been utilized with ED samples to measure eating behaviors, physical activity, sleep, autonomic nervous system activity, eyeblink startle response, visual attention, and visual‐haptic object integration. The reliability and validity of these sensors varies widely and there are a number of significant gaps that remain in the literature with regard to the types of sensors utilized, context in which sensors have been used, and populations studied. Discussion The existing literature utilizing sensors within ED research largely support the feasibility and acceptability of these tools. Sensors should continue to be utilized within the field, with a specific focus on examining the reliability and validity of these tools within ED samples and increasing the diversity of samples studied. Public Significance Statement Sensor technologies, such as those included in modern smartwatches, offer new opportunities to measure factors that may maintain or contribute to symptoms of eating disorders. This article describes the types of sensors that have been used in eating disorders research, challenges that may arise in using these sensors, and discusses new applications of these sensors that may be pursued in future research.

“…Consistent with prior EMA literature, a maladaptive exercise episode was defined as endorsement of ≥3/5 either compensatory or driven exercise (Lampe et al, 2022;Lampe, Forman, et al, 2021;Lampe, Trainor, et al, 2021;Srivastava et al, 2022). This criterion for defining maladaptive exercise was chosen based on clinical significance cutoffs used in extant literature (Karr et al, 2017;Lampe et al, 2022;Lampe, Forman, et al, 2021;Lampe, Trainor, et al, 2021;Srivastava et al, 2022). Because existing definitions of non-maladaptive exercise in the context of binge-spectrum EDs are lacking, we considered any exercise as non-maladaptive which was not categorized as maladaptive (i.e., non-maladaptive episodes were endorsed by participants as <3/5 on both compensatory and driven exercise items), following Centers for Disease Control (2020) guidelines for healthy exercise.…”

Objective: Individuals with eating disorders (EDs) often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating) which maintains eating pathology.Maladaptive exercise has been theorized to help individuals with EDs regulate emotions by enhancing positive affect (PA) and reducing negative affect (NA) associated with binge episodes and poor body image. However, no research has considered the presence of non-maladaptive exercise or evaluated this theory in binge-spectrum EDs.Methods: This study evaluated affective trajectories pre-and post-exercise and examined exercise type (maladaptive or non-maladaptive) as a moderator. We recruited adults with binge-spectrum EDs (N = 107; n = 84 endorsed exercise) to complete a 7-to 14-day ecological momentary assessment protocol assessing NA (anxiety, guilt, and sadness), PA (excitement and cheerfulness), and exercise.Results: There was a significant quadratic trajectory of PA pre-exercise, suggesting that the upward trajectory of PA leveled out as it moved closer to an exercise episode. Exercise type significantly moderated the cubic trajectory of PA post-exercise, such that the upward trajectory of PA accelerated in the hours following nonmaladaptive exercise episodes while the downward trajectory of PA accelerated in the hours following maladaptive exercise episodes. No trajectories of NA demonstrated significant effects.Conclusions: Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA. Future research should evaluate when, and for whom, exercise serves to regulate affect and examine other momentary risk factors of exercise in EDs.Public Significance: Individuals with EDs often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating). Maladaptive exercise has been theorized to help individuals with EDs regulate emotions. This study evaluated affective trajectories pre-and post-exercise and examined whether exercise type (maladaptive or non-maladaptive) changed these trajectories. Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA.

“…Despite the documented negative effects of maladaptive exercise engagement among individuals with BN [8,9],C. [10], a growing body of literature suggests even individuals with EDs can benefit from both overall, general physical activity (i.e., any movement of the body that uses energy) and structured exercise (i.e., structured physical activity undertaken for the primary purpose of getting exercise; [11][12][13][14]). For example, structured adaptive exercise (i.e., non-compensatory exercise, not engaged in with the sole intention to control shape or weight, and non-driven, beneficial associations including stress reduction and socialization) can reduce driven exercise behaviors, drive for thinness, binge eating frequency, compensatory behaviors, and body dissatisfaction [14][15][16][17].…”

Lack of clarity around the role of structured exercise in symptom presentation for individuals with EDs has led to uncertainty about how to address exercise during treatment for individuals with EDs, including individuals with transdiagnostic binge eating and restrictive eating for whom exercise may serve either a compensatory and/or compulsive function.…”

Change in adaptive and maladaptive exercise and objective physical activity throughout CBT for individuals with eating disorders

Maladaptive exercise (i.e., exercise that compensates for binge eating or is used to avoid negative consequences of not exercising-like weight gain) is a common eating disorder (ED) behavior, yet, some individuals with EDs only engage in adaptive exercise. CBT for EDs targets reducing maladaptive exercise but does not address adaptive exercise. Thus, research is limited on how adaptive and maladaptive exercise are impacted during CBT for EDs. The current study examined how assessor-rated adaptive and maladaptive exercise and objectively measured physical activity changed over a 12-week CBT treatment among adults with transdiagnostic binge eating and restrictive eating that did and did not engage in maladaptive exercise at the start of treatment (n = 13 non-maladaptive exercise group, n = 17 maladaptive exercise group). The overall amount of adaptive and maladaptive exercise was measured via the Eating Disorder Examination Interview and objectively measured physical activity (e.g., step count, minutes of moderate-to-vigorous physical activity [MVPA]) was measured via a wrist-worn fitness tracker. Throughout treatment, the overall amount of adaptive exercise did not significantly change for both groups, but the overall amount of maladaptive exercise significantly decreased in the maladaptive exercise group. Step count did not significantly change for both groups, but minutes of MVPA significantly increased over treatment for the non-maladaptive exercise group. Increases in step count and minutes of MVPA were not associated with ED symptom changes in either group. These results enhance an understanding of exercise changes during transdiagnostic CBT-based ED treatment for individuals with varying baseline exercise profiles.Level of evidence: Level 1, randomized controlled trial
