This study examined the capacity of neuropsychological variables indicative of dysfunction in the regulation of executive abilities (e.g. noncompliance with rules) to reflect changes in character associated with disturbances in regulatory abilities (e.g. impulsivity). A close relative of 30 participants with traumatic brain injury (TBI) was administered the(More)
OBJECTIVES To evaluate the reliability and validity of the Apathy Evaluation Scale (AES) and Apathy sub-scale of the Frontal Systems Behavior Scale (FrSBe-A) for people with traumatic brain injury (TBI). To identify an optimal cut-off score indicating presence of apathy according to the AES. METHODS AND PROCEDURES A sample of 34 participants with severe(More)
Rating scales that assess methodological quality of clinical trials provide a means to critically appraise the literature. Scales are currently available to rate randomised and non-randomised controlled trials, but there are none that assess single-subject designs. The Single-Case Experimental Design (SCED) Scale was developed for this purpose and evaluated(More)
BACKGROUND The common legacy of severe degrees of traumatic brain injury is varying degrees and types of impairments, which impact significantly upon the individual's resumption of pre-morbid psychosocial roles. Yet there are few data to indicate the relative contribution of these and other non-injury related variables. METHODS Seventy individuals with(More)
A consecutive series of 100 severely blunt head injured subjects was followed up six years after trauma and the level of psychosocial reintegration was determined for 87 subjects. Three-quarters of the series were classified as demonstrating major disability, having either a Poor Reintegration (33%) or a Substantially Limited Reintegration (43%); the(More)
Recent literature suggests a revival of interest in single-case methodology (e.g., the randomised n-of-1 trial is now considered Level 1 evidence for treatment decision purposes by the Oxford Centre for Evidence-Based Medicine). Consequently, the availability of tools to critically appraise single-case reports is of great importance. We report on a major(More)
BACKGROUND AND AIMS Good assessment is an essential component of effective patient management. Yet the sheer volume of available assessment instruments presents a barrier for the clinician or researcher to (a) be knowledgeable about suitable measures and (b) keep up-to-date with new measures that are published. In order to create a resource of(More)
OBJECTIVE To determine whether social skills deficits including unskilled, inappropriate behavior, problems reading social cues (social perception), and mood disturbances (such as depression and anxiety) could be remediated after severe traumatic brain injuries. DESIGN Randomized controlled trial comparing a social skills program with social activity(More)
PURPOSE To explore factors that may influence exercise adherence in adults with traumatic brain injury (TBI) within the International Classification of Functioning, Disability and Health (ICF) theoretical model. PARTICIPANTS Thirty participants with TBI who had been randomized to a home-based exercise programme in a recently conducted randomized(More)
Perception of emotion in voice is impaired following traumatic brain injury (TBI). This study examined whether an inability to concurrently process semantic information (the "what") and emotional prosody (the "how") of spoken speech contributes to impaired recognition of emotional prosody and whether impairment is ameliorated when little or no semantic(More)
