Objectives: To identify reported (1) common biomechanical asymmetries in the literature after anterior cruciate ligament (ACL) reconstruction in adolescents during landing and (2) timescales for asymmetry to persist postsurgery. Data Sources: We identified sources by searching the CINAHL, PubMed, Scopus, and SPORTDiscus electronic databases using the following search terms: asymmetry OR symmetry AND landing AND biomechanics OR kinematics OR kinetics. Study Selection: We screened the titles and abstracts of 85 articles using our inclusion criteria. A total of 13 articles were selected for further analysis. Data Extraction: Three reviewers independently assessed the methodologic quality of each study. We extracted the effect sizes directly from studies or calculated them for biomechanical variables assessing asymmetry between limbs of participants with ACL reconstruction. We conducted meta-analyses on variables that were assessed in multiple studies for both double- and single-limb landings. Data Synthesis: Asymmetry was more commonly identified in kinetic than kinematic variables. Anterior cruciate ligament reconstruction appeared to have a large effect on asymmetry between limbs for peak vertical ground reaction force, peak knee-extension moment, and loading rate during double-limb landings, as well as mean knee-extension moment and knee energy absorption during both double- and single-limb landings. Conclusions: Our findings suggested that return-to-sport criteria after ACL reconstruction should incorporate analysis of the asymmetry in loading experienced by each limb rather than movement patterns alone.

Psycho-social factors are often addressed in behavioral health studies. While the purpose of many mHealth interventions is to facilitate behavior change, the focus is more prominently on the functionality and usability of the technology and less on the psycho-social factors that contribute to behavior change. Here we aim to identify the extent to which mHealth interventions for patient self- management address psychological factors. By understanding users' motivations, facilitators, and mindsets, we can better tailor mHealth interventions to promote behavior change.

Predictions about the effects of climate change cannot be made with complete certainty, so acknowledging uncertainty may increase trust in scientists and public acceptance of their messages. Here we show that this is true regarding expressions of uncertainty, unless they are also accompanied by acknowledgements of irreducible uncertainty. A representative national sample of Americans read predictions about effects of global warming on sea level that included either a worst-case scenario (high partially bounded uncertainty) or the best and worst cases (fully bounded uncertainty). Compared to a control condition, expressing fully bounded but not high partially bounded uncertainty increased trust in scientists and message acceptance. However, these effects were eliminated when fully bounded uncertainty was accompanied by an acknowledgement that the full effects of sea-level rise cannot be quantified because of unpredictable storm surges. Thus, expressions of fully bounded uncertainty alone may enhance confidence in scientists and their assertions but not when the full extent of inevitable uncertainty is acknowledged.

Reports an error in "Harnessing the placebo effect: Exploring the influence of physician characteristics on placebo response" by Lauren C. Howe, J. Parker Goyer and Alia J. Crum (Health Psychology, 2017[Nov], Vol 36[11], 1074-1082). In the original article, changes were needed to clarify the timeframe over which allergic reactions were measured after the skin prick test (SPT) and the administration of the placebo cream, which was erroneously misrepresented in some cases being “0 to 6 minutes after cream application” when it should have stated “3 to 9 minutes after cream application.” Corrections have been made to reflect this in the “Analytic Strategy for Physiological Results” section and in Figures 2 and 3 and the Figure Notes that accompany them. An additional supplemental figure (Figure S7) has also been added to the supplemental material available online to further clarify the timing of measurements, both in terms of time post-SPT and time post-cream application. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2017-10534-001). Objective: Research on placebo/nocebo effects suggests that expectations can influence treatment outcomes, but placebo/nocebo effects are not always evident. This research demonstrates that a provider’s social behavior moderates the effect of expectations on physiological outcomes. Methods: After inducing an allergic reaction in participants through a histamine skin prick test, a health care provider administered a cream with no active ingredients and set either positive expectations (cream will reduce reaction) or negative expectations (cream will increase reaction). The provider demonstrated either high or low warmth, or either high or low competence. Results: The impact of expectations on allergic response was enhanced when the provider acted both warmer and more competent and negated when the provider acted colder and less competent. Conclusion: This study suggests that placebo effects should be construed not as a nuisance variable with mysterious impact but instead as a psychological phenomenon that can be understood and harnessed to improve treatment outcomes.

Correction Notice: An Erratum for this article was reported in Vol 112(5) of Journal of Personality and Social Psychology (see record 2017-17124-001). In the article, the beginning phrase of the second paragraph of the Internal Meta-Analysis of Studies 3 Through 5 section is incorrect. It should instead begin as follows: Across the three studies. The Monin et al. (2014) reference in both the References list and in text is included in error. The correct citation should read as follows: Monin, B., & Oppenheimer, D. M. (2014). The limits of direct replications and the virtues of stimulus sampling: Commentary on Klein et al., 2014. Social Psychology, 45, 299-300.] Should experts always practice what they preach? When an expert displays exemplary behavior, individuals who fear negative devaluation sometimes anticipate that this expert will look down on them. As a result, displays of excellence can paradoxically turn off the very people they are trying to inspire. Five studies document this in the medical domain, showing that individuals who are overweight or obese and concerned about their weight avoid physicians who advertise their fitness, for fear that these doctors will judge them negatively. People (erroneously) believe that doctors have healthier habits than other individuals (Study 1), doctors advertise healthy habits (Study 2), and overweight individuals anticipate devaluation from, and thus avoid and feel less comfortable with, doctors who portray themselves as fitness-focused (Study 3). Studies 4 and 5 test strategies for physicians to emphasize their own fitness without turning off weight-sensitive patients. This work demonstrates that it is critical to take into account ego-defensive processes when attempting to lead by example.
