OBJECTIVES (1) To determine the summary scores on the Baycrest Multiple Errands Test (BMET) that best discriminate between community dwelling people with traumatic brain injury or stroke and matched controls; (2) to determine interrater reliability; (3) to evaluate further the ecological validity. DESIGN Case-control. SETTING Large,(More)
This study explores the role of cortisol and early life experiences in the regulation of maternal behavior and mood in teen and adult mothers. Primiparous mothers (n=119) (teen mothers < 19 years, n=42), young mothers (19-25 years, n= 4), and mature mothers, (>25 years, n=43) were assessed for their maternal behavior, mood, and hormonal profile at(More)
BACKGROUND This study aimed to explore whether walking in nature may be beneficial for individuals with major depressive disorder (MDD). Healthy adults demonstrate significant cognitive gains after nature walks, but it was unclear whether those same benefits would be achieved in a depressed sample as walking alone in nature might induce rumination, thereby(More)
The purpose of this study was to examine the relationship between executive function and coping at one-year-post traumatic brain injury (TBI). TBI and matched control groups completed a coping questionnaire and a neuropsychological test series. In the TBI group, better executive performance was related to the use of problem focused coping (considered more(More)
Functional brain networks emerge and dissipate over a primarily static anatomical foundation. The dynamic basis of these networks is inter-regional communication involving local and distal regions. It is assumed that inter-regional distances play a pivotal role in modulating network dynamics. Using three different neuroimaging modalities, 6 datasets were(More)
BACKGROUND The benefits of expressive writing have been well documented among several populations, but particularly among those who report feelings of dysphoria. It is not known, however, if those diagnosed with Major Depressive Disorder (MDD) would also benefit from expressive writing. METHODS Forty people diagnosed with current MDD by the Structured(More)
Many people who sustain traumatic brain injuries (TBI) have poor psychosocial outcomes that have been related to the use of avoidant coping. A major obstacle to understanding the mechanisms of this relationship are the self-report measures by which coping has been traditionally evaluated. The purpose of the present study was to compare coping behavior(More)
BACKGROUND Coping has been suggested as the final common pathway related to outcome after traumatic brain injury (TBI). Different types of coping have been related to either positive or negative psychosocial outcomes. As a result, a small set of studies have attempted to remediate coping through intervention, but the effectiveness of these studies has been(More)
The external environment can have a profound impact on our brains and behavior. Yet, even with such a profound impact, it is often easy to ignore just how much the environment can affect us. This is exacerbated by the fact that humans have been able to manipulate their environment so effectively to ease daily life. Even so, the environment shapes our brains(More)
PRIMARY OBJECTIVE Avoidant coping has consistently been related to negative outcomes following traumatic brain injury (TBI), although the mechanisms of this relationship are not clear. A recent study demonstrated that people with moderate-to-severe TBI engaged in more avoidant than planful coping behaviour during a psychosocial stress test, while their(More)
