- The aim of this study was to study the relationship between physician-assessed quality of life parameters, i.e., toxicity and physical performance, and patients' self-reports of their quality of life (QoL). QoL was assessed at baseline and before each treatment, using the EORTC QLQ-C30. The WHO performance score (PS) and toxicity were assessed in physician interviews. The correlations between the WHO PS and the QLQ-C30 functioning scale scores varied from weak to moderate, depending on the scale. Strongest associations were found in physical-, social-, and role functioning, and in the global QoL. The QLQ-C30 nausea/vomiting and diarrhea scales correlated moderately to corresponding WHO scores. A multiple linear regression analysis was used to analyze the contribution of WHO PS and toxicity variables to the global QoL. The best model explained only 16% of the variance of the global QoL score. The present findings highlight the importance of independent QoL assessments focused on those aspects of QoL not captured in clinical interviews with the physician.

Driver ageing does not cause higher accident rates per km
- 2002

Journal article (peer-reviewed)abstract
- Based on Finnish survey data, older (65+, n=1559) and younger (26-40, n=310) drivers' accident rates were compared. In accordance with earlier studies, the rates were similar per driver (0.1) but there was a non-significant trend towards older drivers having more accidents per distance driven (10.8 vs. 8.3 per 1 million km). However, when the accidents-per-km comparison was made in groups matched for yearly exposure, there is no evidence for higher risk with increasing age. In both age groups, risk per km decreased with increasing yearly driving distance. We suggest that the previous perception of an age-related risk increase of accidents per distance driven arises from a failure to control for low mileage bias at all ages. © 2003 Elsevier Science Ltd.

Older drivers' aberrant driving behaviour, impaired activity, and health as reasons for self-imposed driving limitations
- 2002

In: Transportation Research Part F. - 1369-8478 .- 1873-5517. ; 5:1, s. 345-360

Journal article (peer-reviewed)abstract
- The present study used a mail survey addressed to Swedish drivers aged between 55 and 92 years (n = 939) to study the relationship between driving exposure, health, and four types of self-reported aberrant driving behaviour as measured with a Swedish version of the driver behaviour questionnaire. Age and gender were the most important predictors of the tendency to sometimes avoid driving. However, even after accounting for age and gender, reports of own erroneous driving behaviour because of inattention (e.g., failure to notice a signal) and inexperience errors (viz., handling the car), as well as impaired health, were related to self-imposed driving limitations, whereas the violations and mistakes factors were not. Problems with activities of daily living were only marginally associated with self-imposed driving limitations, mediated through inattention and inexperience errors. The results support the notion that older drivers adjust their driving in response to their health and to the problems they experience while driving. © 2002 Elsevier Science Ltd. All rights reserved.
