Purpose: Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted in an influx of data imposing financial and time constraints. This study presents two computational methods that leverage a dataset of video-coded match events: cross-correlation synchronisation aligns iMG data to a video recording, by providing playback timestamps for each HAE, enabling analysts to locate them in video footage; and post-synchronisation event matching identifies the coded match event (e.

Objective: We conducted a survey to catalog the state of open science in the field of psychology and law. We addressed four major questions: (a) How do psycholegal researchers define open science? (b) How do psycholegal researchers perceive open science? (c) How often do psycholegal researchers use various open science practices? and (d) What barriers, if any, do psycholegal researchers face or expect to face when implementing open science practices?

Hypotheses: We did not make specific hypotheses given the exploratory and descriptive nature of the study.

Method: We surveyed 740 psychology and law researchers (45% faculty, 64% doctoral degree, 66% women, and 85% White/non-Hispanic) about their perceptions of and experiences with open science using a mixed-methods design.

Objective: To elucidate the relationship between impaired sleep duration and trauma/posttraumatic stress disorder (PTSD) net of sociodemographic, behavioral, and comorbid diagnostic factors.

Method: We investigated this relationship using the National Epidemiologic Survey on Alcohol and Related Conditions-III data set, analyzing a nationally representative sample of 36,309 adults. Our study identified three groups: those without trauma/PTSD, those with trauma but no PTSD, and those with PTSD.

Research has demonstrated that social-ecological risk and protective factors at multiple levels are associated with sexual behavior in adolescence. However, relatively little is known about how different patterns of these factors may work together in combination to influence sexual risk. In this study, we use nationally representative data from the U.

Introduction: Positionality statements accompanying peer-reviewed publications are increasingly being implemented in academic journals across many disciplines, including psychology. These statements serve as transparent, public acknowledgments of the authors' identities, which can offer valuable insight into the authors' work in the context of their lived experiences and potential biases. However, journal editors and associated staff risk harm by uniformly adopting a policy on positionality statements without consideration of the unintended consequences of implementing such practices.
