Workaholism, an excessive focus on work without apparent economic reason, has been conceptualized by Spence and Robbins (1992) as comprising three dimensions; Work Involvement (WI), Enjoyment (E), and Drive (D). The corresponding measure, the Workaholism Battery (WorkBAT; Spence & Robbins, 1992) is widely used in workaholism research. Cluster and factor analyses in the present study of 320 employed participants failed to confirm Spence and Robbins' three‐scale model of workaholism: only E and D were apparent (α=.85 and .75, respectively). Convergent validity was demonstrated by significant correlations between E and job satisfaction (.48), between D and intrinsic job motivation (.39) and with the Schedule for Nonadaptive and Adaptive Personality—Workaholism scale (E=.27, D=.61). Criterion validity against hours worked was weak (E=.16, D=.22, respectively). Overall, the data endorse Kanai, Wakabayashi, and Fling's (1996) elimination of the Work Involvement factor in favour of a two‐factor structure of workaholism.

Sixty-nine primary caregivers of adults with a severe traumatic brain injury (TBI) were assessed at 1-year post-injury. Caregivers completed questionnaires on the physical, cognitive, emotional, behavioural, and social functioning of the person with TBI. Caregiver objective burden, psychosocial functioning, and subjective burden were also assessed. Clinically significant levels of anxiety and depression were evident in over a third of the caregivers. Similarly, a quarter of the caregivers reported poor social adjustment. There was no consistent relationship between the prevalence of various types of objective burden and the level of subjective distress that resulted from these changes. The person with TBI's emotional difficulties, in particular their anger, apathy, and dependency, caused the greatest distress for caregivers. With regard to the impact that caregiving had on their own lives, caregivers were most distressed by the loss of personal free time. Results from a regression analysis indicated that the person with TBI's physical impairment, number of behavioural problems, and social isolation were the strongest predictors of caregiver burden. The impact that caring for a person with severe TBI can have on the extended family unit is discussed.

Fifty-two primary caregivers of people with a severe traumatic brain injury (TBI) were assessed at 6-months and 1-year postinjury. Caregiver appraisal of the person with TBI's physical, cognitive, emotional, behavioural, and social functioning was assessed. Caregiver psychosocial functioning and levels of subjective and objective burden were also assessed. Some aspects of the difficulties reported for the people with TBI remained stable, while others increased in frequency, over time. At 6-months postinjury, approximately one third of caregivers reported clinically significant symptoms of anxiety and depression, and poor social adjustment. By 1-year postinjury, the prevalence of anxiety and depression remained the same, although only one-quarter continued to report poor social adjustment. There was some evidence of adaptation by caregivers, as the frequency with which various types of objective burden were reported remained stable, while the distress caused by these decreased in the first year postinjury. It appears that the impact on caregivers of physical impairment is comparatively short-lived and that caregivers learn some practical ways to manage the behavioural problems of the people with TBI. Despite this, over time the person with TBI's behavioural and cognitive problems begins to play a larger role in the level of distress experienced by the caregiver. However, it is the person with TBI's social isolation that has a stable and consistent role in the experience of subjective burden for primary caregivers in the first year postinjury.

Sixty-nine primary caregivers of people with a severe traumatic brain injury (TBI) were assessed at 6 months post injury. Caregivers completed questionnaires on the physical, cognitive, emotional, behavioural, and social functioning of the persons with the TBI. Caregiver psychosocial functioning and levels of subjective and objective burden were also assessed. Clinically significant levels of anxiety, depression, and impairment in social adjustment were evident in over a third of the caregivers. The frequency with which various changes in the person with the TBI and types of objective burden were reported had little relationship to the degree of distress caused by these changes. The person with TBI's social isolation and negative emotional behaviours caused the greatest degree of stress for caregivers. Caregivers were also most distressed by the impact that caregiving had on their personal health and free time. The results from a multiple regression analysis suggest that it is the presence of behavioural problems in the person with the TBI that has the most severe and pervasive impact on all aspects of caregiver functioning. It is suggested that these findings be taken into account when providing rehabilitation services to people with TBI and their families.

Normative statistics are provided for the UCLA Loneliness Scale based on the results of a sample of 978 adult subjects collected during a general population health survey. Factor analysis of the data revealed that the scale had a two factor structure; positively worded items loaded on one factor and negatively worded items on the other. Results from the factor analysis were used to construct two equivalent 10‐item short forms of the scale. Previous findings that the scale is highly reliable were confirmed.
