A knowledge transfer (KT) strategy was implemented by the IRSST, an occupational health and safety research institute established in Québec (Canada), to improve the prevention of psychological and musculoskeletal problems among 911 emergency call centre agents. An evaluability assessment was conducted in which each aspect of the KT approach was documented systematically to determine whether the strategy had the potential to be evaluated in terms of its impact on the targeted population. A review of the literature on KT in occupational health and safety and on the evaluation of such KT programmes, along with the development of a logic model based on documentary analysis and semi-structured interviews with key stakeholders, indicated that the KT strategy was likely to have had a positive impact in the 911 emergency call centre sector. Implications for future research are discussed.

Background: Children are exposed to p,p'-dichlorodiphenyltrichloroethane (p,p'-DDT) and p,p'dichlorodiphenyldichloroethylene (p,p'-DDE) through placental and lactational transfer. Some studies have suggested that early-life exposure to these compounds could lead to increased body mass index (BMI) during childhood. Our aim was to assess whether children's exposure during the first 2 years of life is associated with BMI z-score in Japanese children at 42 months of age. Methods: We used data from a birth cohort (n = 290) of the Tohoku Study of Child Development. p,p'-DDT and p, p'-DDE levels were measured in breast milk samples collected 1 month after birth, and levels in children were estimated using a toxicokinetic model for three exposure periods (0-6 months, 6-12 months, 12-24 months). Associations between exposure estimates and BMI z-score at 42 months of age were assessed using multivariate linear regression models. Results: We found no significant association between levels of p,p'-DDT measured in breast milk or estimated in children and BMI z-score. However, we observed associations between estimated p,p'-DDE levels in girls during all postnatal exposure periods and BMI z-score; for each log increase in the estimated p,p'-DDE levels, BMI z-score increased by 0.23 (C.I. 95%: 0.01, 0.45) for the 0-6 months exposure period, 0.26 (C.I. 95%: 0.06, 0.47) for the 6-12 months exposure period, and 0.24 (C.I. 95%: 0.05, 0.43) for the 12-24 months exposure period. Conclusion: In this study of Japanese children, estimated postnatal p,p'-DDE levels were associated with increased BMI z-score at 42 months of age, mostly in girls. These results are in line with previous studies supporting that earlylife exposure to p,p'-DDE may be associated with higher BMI during childhood.

Objective The study examined individual differences between general practitioners (GPs) to determine their impact on variations in intention to refer a hypothetical patient with disordered eating to specialist eating disorder services. The study also examined the impact of patient weight on intention to refer. Method GPs within three primary care trusts (PCTs) were posted a vignette depicting a patient with disordered eating, described as either normal weight or underweight. A questionnaire was developed from the theory of planned behaviour to assess the GPs' attitudes, perception of subjective norms, perceived behavioural control, and intention to refer the patient. Demographic details were also collected. Results Responses were received from 88 GPs (33%). Intention to refer the patient was significantly related to subjective norms and cognitive attitudes. Together these predictors explained 86% of the variance in the intention to refer. GP or practice characteristics did not have a significant effect on the GPs' intention to refer, and nor did the patient's weight. Conclusion Despite National Institute for Health and Clinical Excellence current guidance, patient weight did not influence GPs' decisions to refer. Much of the variance in actual referral behaviour may be explained by cognitive attitudes and subjective norms. Interventions to reduce this variation should be focused on informing GPs about actual norms, and best practice guidelines.

RÉSUMÉCet ouvrage porte sur la conceptualisation, la mesure et la prédiction du bien-être psychologique. Il constitue, en effet, le fruit d'un programme systématique de recherche mené par les auteurs et débouche sur l'élaboration d'un modèle compréhensif et rigoureusement vérifiable du bien-être psychologique. Partant d'un déblayage et d'une organisation conceptuelle de la notion du bien-être psychologique, les auteurs décrivent et évaluent ensuite les principaux instruments de mesure. Les composantes du bien-être sont analysées, pour arriver à la conclusion que le bien-être psychologique est composé d'une dimension affective stable et d'une dimension affective transitoire. Vient ensuite une recension de la recherche sur les prédicteurs psychologiques, sociaux et environnementaux du bien-être. Le modèle théorique proposé dans la conclusion incorpore les aspects situationnels et les dimensions caractérielles. Les auteurs tentent une application des connaissances sur le bien-être psychologique à l'intervention clinique et communautaire ainsi qu'à l'élaboration de politiques sociales.
