In addition to the devastating impact on the individual and their families, suicides on the roads can cause distress and harm to other people who might be involved in a collision or witness an attempt. Despite an increased focus on the characteristics and circumstances of road-related suicides, little is known about why people choose to end their lives in this way.

The aim of the current study was to investigate the factors prompting and deterring the decision to attempt suicide on the roads.

We conducted a secondary analysis of survey data, as well as seven in-depth qualitative interviews. Participants had lived experience of suicidal ideation or behaviour at a bridge or road location. We also carried out an online ethnography to explore interactions in different online communities relating to this method of suicide.

Participants perceived a road-related suicide to be quick, lethal, easy and accessible and to have the potential to appear accidental. The proportion of participants who described their thoughts and attempts as impulsive appeared to be higher than had been observed with other method choices. The potential impact on other people was a strongly dissuasive factor.

Measures designed to prevent access to potentially lethal sites may be particularly important, given that many participants described their thoughts and behaviour as impulsive. In addition, fostering a culture of care and consideration for other road users may help to dissuade people from taking action on the roads.

The psychopathological causes that advise against a bariatric surgical procedure include any state that puts at risk the modification of habits and beliefs regarding eating behavior, wich condition weight loss and health improvement.

To Study the psychiatric profile of patients rejected for bariatric surgery at the Complejo Hospitalario Asistencial de León (León, Spain).

Retrospective observational study. All patients for whom bariatric surgery procedure has been contraindicated for psychopathological reasons are included. 145 patients were evaluated in the context of the protocol for bariatric surgery. The following diagnostic scales were used as support: Salamanca Questionnaire, Plutchik Impulsivity Scale, Attitudes towards change in patients with eating disorders (ACTA), Bulimia Investigatory Test Edinburgh e, and European Quality of Life-5 Dimensions.

41 Patients were rejected for psychiatric reasons (28.28%). The most frequent diagnoses are impulse control disorder (39%), followed by eating disorder (27%). Other diagnoses found are: depressive disorder (10%), adjustment disorder (5%), personality disorders, intellectual disability and generalized anxiety disorder (3%) 78% of them are women.

Uncontrolled psychiatric pathology is a contraindication to bariatric surgery. Impulse control disorder and eating disorder are related to overweight and obesity, so a diagnosis and treatment are necessary prior planning surgical procedure. Psychopathological variables determine the success of bariatric surgery procedures and it is mandatory to consider them in the process.

No significant relationships.

Though moderate exercise has numerous health benefits, some individuals may become excessively preoccupied with exercise, endorsing features akin to “addiction.” The aim of this study was to evaluate the relationships between problematic exercise (viewed dimensionally), quality of life, and psychological measures.

Young adults were recruited from an established population-based cohort in the United Kingdom and completed an online survey. The factor structure of the Exercise Addiction Inventory (EAI) was characterized. Relationships between dimensional EAI factor scores and other variables (impulsivity, compulsivity, emotional dysregulation) were elicited.

Six hundred and forty-two individuals took part in the study (mean age 23.4 years, 64.7% female). The EAI yielded two factors – a “general factor” and a “relationship conflict factor.” Both EAI factor scores were associated with disordered eating, impulsivity (UPPS), and compulsivity (CHI-T). Only the relationship conflict factor score was significantly associated with impaired quality of life (all domains) and with maladaptive personality traits (emotional dysregulation and obsessive-compulsive personality disorder traits). Few participants met conventional threshold for full exercise addiction (1.1%).

Higher problematic exercise scores, in a sample largely free from exercise addiction, were associated with impulsive and compulsive personality features, emotional dysregulation, and disordered eating. Further research is needed to examine whether these results generalize to other populations (such as gym attendees) and are evident using more rigorous in-person clinical assessment rather than online assessment. Longitudinal research is needed to examine both positive and negative impacts of exercise, since moderate exercise may, in fact, be useful for those with impulsive/compulsive tendencies, by dampening negative emotional states or substituting for other more damaging types of repetitive habit.

The concepts of impulsivity and compulsivity are commonly used in psychiatry. Little is known about whether different manifest measures of impulsivity and compulsivity (behavior, personality, and cognition) map onto underlying latent traits; and if so, their inter-relationship.

A total of 576 adults were recruited using media advertisements. Psychopathological, personality, and cognitive measures of impulsivity and compulsivity were completed. Confirmatory factor analysis was used to identify the optimal model.

The data were best explained by a two-factor model, corresponding to latent traits of impulsivity and compulsivity, respectively, which were positively correlated with each other. This model was statistically superior to the alternative models of their being one underlying factor (‘disinhibition’) or two anticorrelated factors. Higher scores on the impulsive and compulsive latent factors were each significantly associated with worse quality of life (both p < 0.0001).

This study supports the existence of latent functionally impairing dimensional forms of impulsivity and compulsivity, which are positively correlated. Future work should examine the neurobiological and neurochemical underpinnings of these latent traits; and explore whether they can be used as candidate treatment targets. The findings have implications for diagnostic classification systems, suggesting that combining categorical and dimensional approaches may be valuable and clinically relevant.
