RESUMO
Limited research has explored the relationship between self-determination theory constructs (basic psychological needs, autonomous/controlled regulation) and internalized weight stigma (IWS). This cross-sectional, online study surveyed 480 U.S. women aged 18-40 between 2021 and 2022. We hypothesized that need frustration and controlled weight regulation would relate to higher IWS, which would be associated with dysfunctional eating, distress, and lower life satisfaction. Conversely, we predicted that need satisfaction, autonomous regulation, and body satisfaction would be associated with reduced IWS, dysfunctional eating and distress, and higher life satisfaction. Structural equation modeling demonstrated an acceptable model fit (CMIN/DF = 2.95, CFI = 0.90, RMSEA = 0.06, SRMR = 0.07), accounting for 74% of IWS variance. Findings indicate the relevance of self-determination theory in understanding IWS, supporting a dual-process model whereby adverse and adaptive outcomes follow distinct pathways. Longitudinal studies are warranted to validate psychological needs and regulatory styles as mechanisms for IWS development and to assess generalizability across diverse populations.
RESUMO
BACKGROUND: Tanzania does not have a formalized prehospital Emergency Medical Services (EMS) response. As a result, traffic police play an integral role in the emergency response system. This study examines the potential impact of a brief training program in prehospital trauma care and mental health to improve knowledge, self-efficacy, and practice intentions related to trauma care among police officers. METHOD: A cohort of 45 police officers were enrolled to participate in the training and accompanying evaluation. The training was 12 h long, held over 3 days, and included education on how to manage traumatic injuries in a prehospital environment. The course included classroom instruction, hands on skills practice, and a training simulation. Officers received instruction on conducting a primary survey, managing common airway, spinal cord, and bleeding emergencies, as well as coping strategies for their own mental health. Before and after the course, a 26-item assessment was administered to measure knowledge, self-efficacy, and practice intentions specific to the training. The study used paired-samples t-tests to compare scores in each of the three domains before and after the training. RESULTS: Participants demonstrated significantly improved knowledge (M = 0.30, SD = 0.27; t(34) = 6.67, p <.001), greater self-efficacy (M = 0.44, SD = 0.53; t(34) = 4.97, p <.001), and more evidence-informed practice intentions (M = 0.12, SD = 0.28; t(34) = 2.55, p <.05) at the conclusion of the course. CONCLUSION: Police officers who received the 12-hour training focused on trauma management were better prepared to respond to emergencies and demonstrated a greater understanding of prehospital trauma care. Further studies are required to assess real world impact of the training and to determine how to increase support for traffic police as emergency medical responders in low-resource settings.
