This is one of the few multivariate studies specifically examining contributors to age-related differences in work injuries in a population-based sample of workers. The substantial reduction in age-work injury association in the fully adjusted model suggests that differences in the types of jobs young workers hold play a critical role in their high-risk status.

Psychometric properties of the newly developed instrument suggest that the application of the Readiness for Change model to return-to-work is relevant to work disability research. The instrument may facilitate the offer of stage-specific services tailored to injured workers' needs, and be used for evaluation of return-to-work interventions.

Aims: This study examined the relation between months on the job and lost-time claim rates, with a particular focus on age related differences. Methods: Workers' compensation records and labour force survey data were used to compute claim rates per 1000 full time equivalents. To adjust for potential confounding, multivariate analyses included age, sex, occupation, and industry, as well job tenure as predictors of claim rates. Results: At any age, the claim rates decline as time on the job increases. For example, workers in the first month on the job were over four times more likely to have a lost-time claim than workers with over one year in their current job. The job tenure injury associations were stronger among males, the goods industry, manual occupations, and older adult workers. Conclusions: The present results suggest that all worker subgroups examined show increased risk when new on the job. Recommendations for improving this situation include earlier training, starting workers in low hazard conditions, reducing job turnover rates in firms, and improved monitoring of hazard exposures that new workers encounter.

Participants in a study of the correlates of courtship aggression included 408 college students (125 males, 283 females) who were involved in a dating relationship of two months or longer. Subjects completed self-report measures of courtship aggression, family aggression, personality, dating problems, problem solving, life change, and personal history of aggression. The pattern of significant correlations differed for men and women. The variables significantly discriminated between aggressive and nonaggressive individuals, for both men and women. The contribution of the individual variables to the discriminant function was also determined. The variables measuring relationship problems, problem-solving ability, and a history of fighting contributed to the discrimination of aggressive and nonaggressive men. For the women, the number of relationship problems and an aggressive personality made significant individual contributions.

Injuries at work have a substantial economic and societal burden. Often groups of labour market participants, such as young workers, recent immigrants or temporary workers are labelled as being "vulnerable" to work injury. However, defining groups in this way does little to enable a better understanding of the broader factors that place workers at increased risk of injury. In this paper we describe the development of a new measure of occupational health and safety (OH&S) vulnerability. The purpose of this measure was to allow the identification of workers at increased risk of injury, and to enable the monitoring and surveillance of OH&S vulnerability in the labour market. The development included a systematic literature search, and conducting focus groups with a variety of stakeholder groups, to generate a pool of potential items, followed by a series of steps to reduce these items to a more manageable pool. The final measure is 29-item instrument that captures information on four related, but distinct dimensions, thought to be associated with increased risk of injury. These dimensions are: hazard exposure; occupational health and safety policies and procedures; OH&S awareness; and empowerment to participate in injury prevention. In a large sample of employees in Ontario and British Columbia the final measure displayed minimal missing responses, reasonably good distributions across response categories, and strong factorial validity. This new measure of OH&S vulnerability can identify workers who are at risk of injury and provide information on the dimensions of work that may increase this risk. This measurement could be undertaken at one point in time to compare vulnerability across groups, or be undertaken at multiple time points to examine changes in dimensions of OH&S vulnerability, for example, in response to a primary prevention intervention.
