Road traffic crashes are one of the global public health concerns and remain at high priority in many countries. AT527 Driving under the influence of drugs increases the risk of crashes through altering the driver's mental state and reactions. This study was conducted to determine the relationship between driving pattern and substance abuse among drivers in Kerman, a city in Iran, in order to enable policy makers to make the necessary decisions in planning and executing guidelines. The population of this descriptive study was drivers involved in road traffic crashes admitted to the emergency department of Shahid Bahonar university hospital in summer 2019. After obtaining demographic information, type of vehicle, type of collision and pattern of serious injury, 222 eligible drivers were tested for tramadol, cannabis, amphetamine, methamphetamine, morphine and methadone using one step urine test strips. Chi-square test, Fisher's exact test, Whitney-Mann and Kruskal-Wallis tests and one-way Anova test was performe, especially methadone, has undoubtedly a significant role in both road traffic crashes and resulted injuries. The high rate of injuries on drivers influenced by methadone in traffic crashes needs to be screened and prevented. It is recommended to not only authoritatively deal with the excessive supply of methadone in the community but also restricting the driving of people receiving methadone treatment.On the basis of converging research, we concluded that the controversial topic of unconscious blockage of psychological trauma (i.e., repressed memory) remains very much alive in clinical, legal, and academic contexts. In his commentary, Brewin (this issue, p. 443) conducted a cocitation analysis and concluded that scholars do not adhere to the concept of unconscious repression. Furthermore, he argued that previous survey research did not specifically assess unconscious repression. Here, we present critical evidence that runs counter to his claims. First, we inspected his cocitation analysis and found that some scholars support notions that are closely related to unconscious repression. Furthermore, we conducted another analysis on the basis of articles' similarity. Again, we found examples of scholars specifically endorsing unconscious repressed memories. Second, as opposed to what Brewin reports, recent survey research now exists that bears directly on people's beliefs regarding unconscious repression. This work reveals that large percentages of people (e.g., students and eye-movement desensitization and reprocessing [EMDR] clinicians) endorse the concept of unconscious repressed memories. The belief in unconscious repressed memory can continue to contribute to harmful consequences in clinical, legal, and academic domains (e.g., false accusations of abuse).In a prior publication, I used structural equation modeling of multimethod data to examine the construct validity of Implicit Association Tests. The results showed no evidence that IATs measure implicit constructs (e.g., implicit self-esteem, implicit racial bias). This critique of IATs elicited several responses by implicit social-cognition researchers, who tried to defend the validity and usefulness of IATs. I carefully examine these arguments and show that they lack validity. IAT proponents consistently ignore or misrepresent facts that challenge the validity of IATs as measures of individual differences in implicit cognitions. One response suggests that IATs can be useful even if they merely measure the same constructs as self-report measures, but I find no support for the claim that IATs have practically significant incremental predictive validity. In conclusions, IATs are widely used without psychometric evidence of construct or predictive validity.This systematic review aimed to synthesize the evidence of the psychometric properties of self-efficacy patient-reported outcome measures (PROMs) in patients with chronic obstructive pulmonary disease (COPD). We conducted a systematic search of MEDLINE and other common databases from inception until September 2020. Studies that reported psychometric properties of self-efficacy outcome measures in COPD patients were included. We used the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) 2018 guidelines for data extraction and evidence synthesis. Eighteen studies that assessed nine self-efficacy PROMs were eligible for inclusion. The assessment of structural validity indicated sufficient results rating for the Exercise Self-Regulatory Efficacy Scale and the Self-Care-Self-Efficacy Scale, and insufficient rating for the COPD Self-Efficacy Scale and the Pulmonary Rehabilitation Adaptation Index for Self-Efficacy (PRAISE). Construct validity measures displayed sufficient results rating with correlations ranging from -0.48 to - 0.71 between self-efficacy PROMs and other PROMs such as St. George's Respiratory Questionnaire, Hospital Anxiety and Depression Scale and Chronic Respiratory Questionnaire. Internal consistency measures indicated sufficient rating for all self-efficacy PROMs with a Cronbach's alpha range of 0.71 - 0.98. Responsiveness was assessed for the PRAISE with an overall sufficient rating (effect sizes of 0.21 - 0.37). The evidence regarding the psychometric properties of self-efficacy PROMs in COPD is variable. The PRAISE is responsive to changes in self-efficacy in COPD patients attending a pulmonary rehabilitation program. When using self-efficacy PROMs in clinical practice or research, clinicians and researchers should consider the psychometric properties and choose the appropriate outcome measure based on the purpose. There is a paucity of data on the incidence and severity of tram tracks related cycling injuries. The aim of this study is to get insight into the incidence, severity and characteristics of tram tracks related cycling injuries, potentially defining significant 'hotspots' in the Ghent city area. A one-year, multicenter, prospective, observational study was conducted. Patients presenting to the emergency departments of all 4 Ghent hospitals with tram tracks related cycling injury, were included. Data on patient demographics, circumstances of the accident and type of injury were collected. 149 patients were included, with a median age of 31 years. 42 patients had fractures, 39 patients required wound sutures, 79 and 49 patients suffered from bruising and abrasions respectively. Only 5 patients required admission. No patients died or suffered life-threatening injuries. Women (65.1%) presented more frequently than men (34.9%). Forty-tree percent of all accidents happened in autumn (  < 0.001). Accidents happened more frequently in rainy conditions (  < 0.
