Objective The goal of this pilot study was to assess the feasibility of a 9-day, smartphone-based ecological momentary assessment (EMA) protocol to track the frequency of Canadian adolescents’ exposures to cannabis marketing, their reactions to such exposures, and the context in which exposures occur in the real-world and in real-time. Method Part...

Individuals that possess and utilize their strengths have higher reports of subjective and psychological well-being. However, it remains unclear as to whether certain domains of strengths (e.g., strengths at home, at school, within the community) are more strongly associated with certain indices of well-being (e.g., stress management, social connec...

The abilities to experience and understand another person’s feelings (empathy), to successfully cope with stress (resilience), and to harness personal skills (psychological strengths) are dynamic qualities that may be associated to an adolescent’s perception of care from others (i.e., family, friends, school staff, and significant others). Although...

Background: Our goal was to examine the relationship between age and engine displacement in cubic centimeters (CCs) and crash responsibility. Methods: Male motorcyclists, aged 16-94, involved in a fatal crash in the United States (1987-2015) who tested negative for both drugs and alcohol were included. Employing a case control design, cases had...

Trait perfectionism has often been studied in competitive situations. Although past research has examined trait perfectionism and competitiveness, the two constructs have not been directly compared in a lab-based competitive task. The primary objectives of the study were to examine the associations between the three facets of the Multidimensional P...

Objective Few studies have investigated the association between broad personality traits and motorcycle rider behaviours. Typically, studies have focused on specific variables such as Sensation Seeking and Aggression. This study extends the literature by investigating the trait facets of the Big Five and the Reinforcement Sensitivity Theory (RST)....

The importance of examining positive aspects of youth development has been emphasized across disciplines involved in the care of youth with substance abuse problems. However, little is known about the strengths of adolescents with substance abuse problems, especially youth entering residential treatment. Utilizing the Strengths Assessment Inventory...

Prior research has demonstrated relationships between neuroticism, perfectionism, and social anxiety. This study examined whether trait perfectionism (particularly socially prescribed perfectionism [SPP]) and perfectionistic self-presentation predicted social interaction and evaluation anxiety while controlling for neuroticism. It also explored whi...

AbstrAct The treatment efficacy of mindfulness for improved quality of life and health-related symptoms has reliably been found in the literature. Questionnaires have been developed to assess both state mindfulness (Toronto Mindfulness Scale, TMS) and trait mindfulness (Philadelphia Mindfulness Scale, PHLMS). The objective of this study was to dire...

Despite the utility of examining competitiveness across different contexts, current competitiveness scales lack the ability to unify trait competitiveness into one comprehensive measure. The goal of the present study was to construct one, psychometrically sound, multidimensional scale that would serve to correctly and concisely measure competitiven...

We sought to determine if we could reduce symptoms of depression in individuals with a traumatic brain injury using mindfulness-based cognitive therapy. The study was conducted in a community setting. We enrolled adults with symptoms of depression after a traumatic brain injury. We conducted a randomized controlled trial; participants were randomiz...

Mindfulness-based cognitive therapy (MBCT) is a relatively new therapeutic approach that is rooted in mindfulness-based stress reduction and cognitive behavioral therapy. Leading MBCT requires a radically different method than other forms of group facilitation. We are currently conducting a multi-site, randomized controlled trial (RCT) of a mindful...

Understanding the factors that contribute to problem gambling (PG) is imperative. Individual differences in sensation seeking (SS), as measured by the Sensation Seeking Scale Form (SSS-V), have been found to be predictive of PG among university student samples. However, what is less clear, is if the four SSS-V subscales capture unique facets of SS...

CONTEXT: Current therapies for traumatic brain injury (TBI) include pharmacotherapy, psychotherapy, and cognitive rehabilitation. Unfortunately, psychological and emotional issues regularly go untreated in individuals with TBI even after they receive treatment for physical, behavioral, and cognitive issues. Mindfulness-based cognitive therapy (MBCT...

Three avoidance measures, the Miller Behavioural Style Scale (MBSS), Index of Self-Regulation of Emotion (ISE) and Mainz Coping Inventory (MCI), were compared in their ability to predict attention and avoidance of threats in the emotional Stroop task. It was also examined if the avoidance mechanism of individuals who would normally avoid threat-ind...

The present study evaluates the mental health of participants 3 to 6 months after completing treatment at a shared mental health care clinic. Twenty-five participants completed the Patient Health Questionnaire (PHQ) and the World Health Organization Disability Assessment Scale version II (WHODAS-II) at entry, exit, and 3 to 6 months following treat...

To examine the potential efficacy of a mindfulness-based stress reduction approach to improve quality of life in individuals who have suffered traumatic brain injuries. Pre-post design with drop-outs as controls. We recruited individuals with mild to moderate brain injuries, at least 1 year post-injury. We measured their quality of life, psychologi...

To determine the prevalence of renal impairment and the dosage appropriateness of several medications for which dosing guidelines in the advent of renal impairment are available. The authors assessed the renal function and medication use of 37 psychogeriatric patients (mean age of 75 years) living in a psychiatric hospital. Renal function was deter...

The present research investigates the determinants of the cognitive tendency to avoid thoughts about sexually transmitted infection (STI) and examines the association of this tendency with willingness to engage in discussions of safer sexual practices and with condom use consistency. Findings from two questionnaire-based studies are presented. The...
