RESUMO

The COVID-19 pandemic altered daily life in the United States and disrupted how people engage in routine health behaviors, such as physical activity (PA). This study investigates factors that may have helped people sustain recommended levels of moderate to vigorous PA (MVPA) during this time. Using a cross-sectional design, we recruited from Amazon's Mechanical Turk in April/May 2020 a sample of individuals who reported that they had met recommended PA guidelines (≥ 150 weekly MVPA minutes; N = 397) prior to structural changes brought about by COVID-19. We assessed via self-report whether these individuals were meeting recommended levels of MVPA during the COVID-19 pandemic, their intrinsic motivation and identified regulation for exercise, exercise self-efficacy, perceived disruption to their exercise routine, and access to resources for PA. Higher identified regulation, self-efficacy, access to PA resources, and lower perceived disruption were associated with meeting PA guidelines during COVID-19. These findings provide insight into factors that may be important for continued engagement in MVPA when one experiences major disruptions to their exercise routine.Supplemental data for this article is available online at https://doi.org/10.1080/08964289.2021.1929811 .

RESUMO

Recent research has examined psychological factors that forestalled declines in physical activity (PA) during the early stages of the COVID-19 pandemic. Surprisingly, there has been limited evidence of an association between intrinsic motivation (IM) and PA. We reasoned that IM may have not predicted PA because COVID-19 restrictions limited opportunities to engage in exercise in ways that produced positive affective experiences (i.e., inherent rewards). Using data from a cross-sectional survey (N = 373 participants), we tested a moderated mediation model that predicted perceived changes to affective experiences during exercise would mediate the association between disruption to one's exercise routine and self-reported declines in PA, and that effects would be moderated by IM. Evidence of moderated mediation was found, suggesting that disruptions to exercise routines were associated with fewer positive affective experiences during exercise that predicted declines in PA engagement, especially for people who typically exercised for intrinsic reasons.

RESUMO

What is the role played by attentional load in eating? Does attending to an unrelated task generally lead to overeating, perhaps by preventing individuals from focusing on a goal to limit consumption? Or does such attentional diversion typically lead to reductions in eating, perhaps by preventing people from noticing tempting features of relevant food cues? Past research has supported each of these two propositions, but comparisons between existing studies have been hampered to the extent that various experimental manipulations differ in the degree to which they occupy attention, as well as differing in the particular type of attentional resources they exploit. To resolve existing discrepancies in the literature, in a series of studies, we made use of a working memory manipulation, the n-back task (Kirchner, 1958), that can be systematically modified to induce varying levels of cognitive load, allowing for rigorous comparisons of the effects of different levels of attentional load on eating. These studies revealed a complex pattern of results. Analysis of findings from three studies employing within-subjects designs documented a linear relationship, in that participants consumed less food when completing a higher cognitive-load task than when completing a lower cognitive-load task. Three studies employing between-subjects designs highlighted a less consistent pattern of results, but when combined in a mini-meta-analysis, suggested the opposite linear relationship, with participants assigned to higher cognitive-load conditions generally consuming more food than participants assigned to lower cognitive-load conditions. We conducted two additional studies to reconcile these conflicting patterns of data. Neither finding received unequivocal support, although both studies found that participants ate less when engaged in higher cognitive-load tasks than lower cognitive-load tasks. The precise nature of the relationship between attentional load and eating remains elusive.

RESUMO

OBJECTIVE: This study examines the impact of COVID-19 restrictions on exercise routines and engagement in moderate-vigorous physical activity (MVPA). DESIGN: Individuals (N = 397) who reported meeting recommended guidelines for MVPA prior to COVID-19 completed an online questionnaire during the United States' COVID-19 lockdowns in April/May 2020. MAIN OUTCOME MEASURES: Participants reported their MVPA currently and before COVID-19, and answered questions about five contextual cues (e.g. time of day, interaction partners, type of workout, surrounding events, location of exercise) that characterized their exercise routines currently and before COVID-19. RESULTS: Contextual cues were perceived as highly disrupted and less consistent during COVID-19 (vs. before) and these changes were associated with greater declines in MVPA. For each cue, distinct effects predicting MVPA declines also emerged for perceived disruption due to COVID-19 restrictions, perceived importance of cue in getting one to exercise, and cue consistency over time. CONCLUSION: Building on prior research, COVID-19 restrictions affected the context in which people exercised, and changes in these contextual cues were related to declines in MVPA. Re-establishing consistency in certain cues (e.g. time of day) after a disruption may help to forestall declines in MVPA compared to others (e.g. type of workout).

RESUMO

Research suggests that people differ more in their ability to lie than in their ability to detect lies. However, because studies have not treated senders and messages as separate entities, it is unclear whether some senders are generally more transparent than others or whether individual messages differ in their transparency of veracity regardless of senders. Variance attributable to judges, senders, and messages was estimated simultaneously using multiple messages from each sender (totaling more than 45,000 judgments). The claim that the accuracy of a veracity judgment depends on the sender was not supported. Messages differed in their detectability (21% explained variance), but senders did not. Message veracity accounted for most message variation (16.8% of the total variance), but other idiosyncratic message characteristics also contributed significantly. Consistent with the notion that a (mis)match between sender demeanor and veracity determines accuracy, lie and truth detectability differed individually within senders. Judges primarily determined variance in lie-versus-truth classifications (12%) and in confidence (46%) but played no role regarding judgment accuracy (< 0.01%). This work has substantial implications for the design and direction of future research and underscores the importance of separating senders and messages when developing theories and testing derived hypotheses.

RESUMO

OBJECTIVE: Psychological network analysis was used to evaluate the relations between beliefs about cigarette smoking in current smokers with and without a recent quit attempt and determine if these networks differed in global strength (how strongly beliefs are related) or global structure (which beliefs are related). DESIGN: Using two publicly available datasets, the California Smokers' Cohort (CSC; N = 933) and Wave 1 of the Population Assessment of Tobacco and Health (PATH; N = 7855), we evaluated differences in global strength and global structure of the beliefs held by current smokers with and without a recent quit attempt. MAIN OUTCOME MEASURES: Strength and structure of networks generated for current smokers with and without a recent quit attempt. RESULTS: In the CSC dataset there were differences between smokers with and without a recent quit attempt in global structure and marginal differences in global strength; the PATH dataset suggested small differences in global strength and structure. CONCLUSION: The present study suggests that consideration of relations among smoking beliefs may be a valuable contribution to characterizing smoking beliefs when assessing smoking quit attempts.

RESUMO

The COVID-19 pandemic has extensively changed the state of psychological science from what research questions psychologists can ask to which methodologies psychologists can use to investigate them. In this article, we offer a perspective on how to optimize new research in the pandemic's wake. Because this pandemic is inherently a social phenomenon-an event that hinges on human-to-human contact-we focus on socially relevant subfields of psychology. We highlight specific psychological phenomena that have likely shifted as a result of the pandemic and discuss theoretical, methodological, and practical considerations of conducting research on these phenomena. After this discussion, we evaluate metascientific issues that have been amplified by the pandemic. We aim to demonstrate how theoretically grounded views on the COVID-19 pandemic can help make psychological science stronger-not weaker-in its wake.

RESUMO

OBJECTIVE: To evaluate the intubation success rates of residents who receive coaching from supervisors concurrently viewing infants' airways via video during direct laryngoscopy (VDL), as compared with coaching during traditional direct laryngoscopy without video (TDL). STUDY DESIGN: In a randomized controlled trial, 48 first and second-year residents performed neonatal intubations using VDL or TDL. The primary outcome was intubation success rates. Data were analyzed using the Pearson X2 and Student's t-test. RESULTS: The overall intubation success rate was greater in the VDL vs. TDL group (57% vs. 33%, P < 0.05). First-year residents and residents intubating their first patient had higher intubation success rates in the VDL vs. TDL group (58% vs. 23% and 50% vs. 17%, respectively, P < 0.05). CONCLUSIONS: Resident coaching using VDL improved neonatal intubation success rates. Incorporating VDL as a coaching tool can optimize the quality of training during limited opportunities to achieve procedural competency and improve intubation-related patient outcomes.

RESUMO

Children of smokers are significantly more likely to experiment with cigarettes and become habitual smokers than children of nonsmokers. The current study examined the effect of parental smoking on children's implicit and explicit responses toward smoking behavior and smoking-related cues with the goal of identifying potential mechanisms for this relationship. A sample of 8-12-year-old children of smokers (n = 57) and children of nonsmokers (n = 86) completed a dot probe task to assess implicit attentional bias toward smoking cues and the Affect Misattribution Procedure (AMP) to assess implicit affective responses to smoking cues. In addition, children indicated their explicit perceptions of smokers and smoking behavior. Results demonstrated that children of smokers showed more sustained implicit attentional bias toward pictures of smoking stimuli presented alone than children of nonsmokers. Overall, participants showed negative implicit affective responses to smoking stimuli regardless of parental smoking. Children of smokers indicated that smokers would experience fewer negative consequences than children of nonsmokers; these relationships were moderated by age. Together, our findings suggest that parental smoking affects the ways that preadolescent children implicitly process smoking cues and their perceptions about smoking and its consequences. These findings help us understand the environmental mechanisms associated with smoking behavior in this vulnerable population. (PsycINFO Database Record (c) 2018 APA, all rights reserved).
