The Driver Behavior Questionnaire (DBQ) is a self-report measure of driving behavior that has been widely used over more than 20 years. Despite this wealth of evidence a number of questions remain, including understanding the correlation between its violations and errors sub-components, identifying how these components are related to crash involvement, and testing whether a DBQ based on a reduced number of items can be effective. We address these issues using a bifactor modeling approach to data drawn from the UK Cohort II longitudinal study of novice drivers. This dataset provides observations on 12,012 drivers with DBQ data collected at .5, 1, 2 and 3 years after passing their test. A bifactor model, including a general factor onto which all items loaded, and specific factors for ordinary violations, aggressive violations, slips and errors fitted the data better than correlated factors and second-order factor structures. A model based on only 12 items replicated this structure and...

Drivers are at high crash risk when they begin independent driving, with liability decreasing steeply over the first three months. Their behavioural development, and other changes underlying improved safety are not well understood. We adopted an innovative longitudinal qualitative design, with thirteen newly qualified drivers completing a total of 36 semi-structured interviews, one, two and three months after acquiring a full UK driving license. The interviews probed high-risk factors for new drivers, as well as allowing space for generating novel road safety issues. Analysis adopted a dual deductive and inductive interpretative thematic approach, identifying three super-ordinate themes: (1) Improvements in car control skills and situation awareness; (2) A reduction in the thrill of taking risks when driving against a background of generally increasing driving speed; (3) Early concerns about their social status in the eyes of other road users during the early stages of driving, whic...

To provide the best possible evidence base for guiding driving decisions in Parkinson disease (PD), we performed a meta-analysis comparing patients with PD to healthy controls (HCs) on naturalistic, on-the-road, and simulator driving outcomes. Seven major databases were systematically searched (to January 2018) for studies comparing patients with PD to HCs on overall driving performance, with data analyzed using random-effects meta-analysis. Fifty studies comprising 5,410 participants (PD = 1,955, HC = 3,455) met eligibility criteria. Analysis found the odds of on-the-road test failure were 6.16 (95% confidence interval [CI] 3.79-10.03) times higher and the odds of simulator crashes 2.63 (95% CI 1.64-4.22) times higher for people with PD, with poorer overall driving ratings also observed (standardized mean differences from 0.50 to 0.67). However, self-reported real-life crash involvement did not differ between people with PD and HCs (odds ratio = 0.84, 95% CI 0.57-1.23, = 0.38). Fin...

Background Despite the enormous financial and humanistic burden of chronic low back pain (CLBP), there is little consensus on what constitutes the best treatment options from a multitude of competing interventions. The objective of this network meta-analysis (NMA) is to determine the relative efficacy and acceptability of primary care treatments for non-specific CLBP, with the overarching aim of providing a comprehensive evidence base for informing treatment decisions. Methods We will perform a systematic search to identify randomised controlled trials of interventions endorsed in primary care guidelines for the treatment of non-specific CLBP in adults. Information sources searched will include major bibliographic databases (MEDLINE, Embase, CENTRAL, CINAHL, PsycINFO and LILACS) and clinical trial registries. Our primary outcomes will be patient-reported pain ratings and treatment acceptability (all-cause discontinuation), and secondary outcomes will be functional ability, quality o...

Individual differences in psychophysiological function have been shown to influence the balance between flexibility and distractibility during attentional set-shifting [e.g., Dreisbach et al. (2005). Dopamine and cognitive control: The influence of spontaneous eyeblink rate and dopamine gene polymorphisms on perseveration and distractibility. Behavioral Neuroscience, 119(2), 483–490]. Here we replicate both the facilitatory and detrimental influence of spontaneous eyeblink rate upon switch costs across the two distinct conditions of a set-shifting task. We extend this by presenting additional, putatively dopamine related, individual differences that also influence attentional control. Whereas trait psychoticism showed a pattern of effects opposite to that of eyeblink rate, greater working memory served to decrease switch costs across both conditions. These results highlight the need for further exploration of the role of dopaminergic neurotransmission and component processes involved in such attentional paradigms, and illustrates the importance of considering individual differences in cognitive control.

Background
Mental Health Literacy (MHL) predicts help-seeking for mental health difficulties. Public surveys show high recognition of Post-Traumatic Stress Disorder (PTSD) in relation to military contexts, but this has not been investigated with other sources of trauma.
Methods
A self-selecting sample of 2960 participants from UK and Ireland completed an online survey. Participants viewed one of three vignettes that described either a male or female character experiencing identical PTSD symptoms, that differed only by trauma source (military combat, industrial accident, sexual assault). Participants were asked to state i) whether a mental health problem was being experienced, ii) what it was, and iii) what help should be sought.
Results
Trauma type was a key predictor of classification as a mental health problem, correct identification of PTSD, and help-seeking suggestions. For participants shown the military scenario the odds of recognising PTSD were 5.2 times higher than for those shown the sexual assault vignette, and 2.2 times higher than for those shown the accident scenario. Age (younger), gender (female), education (university), and personal mental health experience were additional significant predictors of higher recognition of PTSD.
Limitations
Reasons for failing to recognise a mental health problem/PTSD were not explored. The online convenience sampling method may limit generalisability of results.
Conclusions
Recognition of PTSD is significantly affected by trauma source. The data confirmed the pervasive association with military combat and suggest under-recognition of PTSD from other traumas, particularly sexual assault. Awareness campaigns may aim to increase MHL of PTSD from diverse trauma sources.

This paper reviews the research on psychedelic substances in relation to so-called paranormal phenomena, such as telepathy, clairvoyance, and precognition (i.e., ESP), as well as out-of-body experiences (OBEs) and near-death experiences (NDEs). Reference is made to the age-old shamanic use of these substances to specifically induce such experiences, and to contemporary reports from within academia and psychotherapy bearing witness to such phenomena. However, the review focuses primarily on describing and critically evaluating the contribution of controlled experiments that have attempted to induce ESP using psychedelics, and of surveys, which have either directly or indirectly investigated the belief in, and experience of, the paranormal in relation to the use of such substances. Furthermore, a methodological critique of the experimental research is offered alongside some recommendations for further research in this field.

The occurrence of transpersonal experiences with psychedelic substances is well attested, and several surveys have consistently found a small relationship between paranormal experiences and the use of such drugs in general. Isolated investigations of experiences with specific drugs exist, but no surveys have systematically examined whether particular experiences relate to particular drugs. In an online survey, 139 respondents were recruited through parapsychology or psychedelic interest groups and completed a questionnaire detailing psychoactive drug-use behaviour and the frequency of occurrence of a number of paranormal, shamanic, and mystical type experiences. Patterns of drug-induced transpersonal experiences reported elsewhere were mostly corroborated, particularly the proclivity for telepathic experiences with cannabis, out-of-body experiences with ketamine, entity encounter experiences with N,N-dimethyltryptamine (DMT), and plant-spirit encounters with a host of psychedelic plants. Several small correlations were found between drug-use frequency and experience frequency with certain drug and experience types, particularly those termed mystical. As expected, alcohol and opiate/opioid-use did not correlate with any transpersonal experiences although, surprisingly, no sizable correlations were found for psi experiences and the use of any one type of drug, possibly due to the high rate of occurrence of psi experiences among both drug users and non-drug users with this particular sample.
