This study explores the relationship between time perspective (TP), cannabis use and risk perceptions associated with this substance. A sample of French students (n ¼ 198) were provided with a valid French version of the Zimbardo Time Perspective Inventory (ZTPI) scale. Risk perceptions linked to cannabis consumption were evaluated from a list of 22 items referring to different risks. Respondents were asked to declare how frequently they consumed this substance. Data analysis was based firstly on ZTPI scores, secondly on declared consumption and finally on the two risk perception indices which were established after factorial analysis. Results showed that TP acted as a significant predictor of both psychoactive substance use and of cannabis consumption frequency. Significant links between consumption and risk perceptions also appeared. A second series of analyses showed that TP moderated the link between cannabis consumption and risk perceptions. These findings highlight the importance of TP when analyzing the complexity of contemporary cannabis use.

The aim of this study was to document how breast cancer patients perceive their prognosis and a tailored treatment based on tumour gene expression analysis, and to identify the features of this approach that may impact its clinical application. In-depth interviews were conducted at three French cancer centres with 37 women (35-69 years of age) with node-positive breast cancer undergoing an adjuvant chemotherapy regimen defined on the basis of the genomic signature predicting the outcome after chemotherapy. Several concerns were identified. First, some misconceptions about these methods were identified due to semantic confusions between the terms 'genomic' and 'genetic', which generated anxiety and uncertainty about the future. Second, the 'not done' and 'not interpretable' signatures were misinterpreted by the women and associated with highly negative connotations. However, the use of tumour genomic analysis to adapt the treatment to each patient received most of the patients' approval because it was perceived as an approach facilitating personalised medicine. In conclusion, improving the quality of provider/patient communications should enable patients to play a more active part in the decision making about their treatment. This will ensure that those who agree to have tumour gene analysis have realistic expectations and sound deductions about the final result disclosure process.

In this article, we assess the structural equivalence of the Zimbardo Time Perspective Inventory (ZTPI) across 26 samples from 24 countries (N = 12,200). The ZTPI is proven to be a valid and reliable index of individual differences in time perspective across five temporal categories: Past Negative, Past Positive, Present Fatalistic, Present Hedonistic, and Future. We obtained evidence for invariance of 36 items (out of 56) and also the five-factor structure of ZTPI across 23 countries. The short ZTPI scales are reliable for country-level analysis, whereas we recommend the use of the full scales for individual-level analysis. The short version of ZTPI will further promote integration of research in the time perspective domain in relation to many different psycho-social processes.

RESUME -La relation du contexte social et de la santé représente un enjeu de recherche important pour les développements actuels en psychologie sociale de la santé. L'approche des représentations sociales offre un cadre d'analyse de la pensée sociale profane concernant la maladie, en rupture avec la tradition cognitiviste et individualiste dominante dans les analyses psychosociales des risques sanitaires. Sur le plan théorico-méthodologique, cette approche permet une étude contextualisée des processus sociocognitifs qui interviennent dans la construction des risques, en opérationnalisant la double nature, produit/ processus, de la représentation. Dans cette perspective, la triangulation en tant que stratégie de recherche inductive constitue une démarche privilégiée. Nous présentons une application de cette stratégie à travers une recherche sur les représentations des relations sexuelles et des risques liés au sida chez de jeunes adultes en France et en Grèce. Nous discutons la pertinence de la triangulation pour les approches "multi-niveaux" de la construction des risquesl.Mots-clés: représentations sociales; triangulation; risques sanitaires. Social Representations and Triangulation: An Application in Social Psychology of HealthABSTRACT -The relationship between social context and health represents an important research issue, which is at the centre of current developments of social psychology of the health. The social representational approach offers a frame to analyze common sense thinking about illness. This approach breaks with the cognitive and individualistic tradition that dominated the social psychological analysis of health risks. Concerning theory and methodology this approach enables a contextualized study of the socio-cognitive processes that intervene in the construction of risks through the operationalisation of the double nature -product/process-of the representation. Thus, triangulation as an inductive strategy of research constitutes a privileged approach. We present an application of this strategy through a research program concerning the representations of sexual relationships and AIDS-related risks of young adults in France and Greece. The pertinence of triangulation for the analysis of risk's construction within approaches that seek a multilevel explanation is discussed.Key words: social representations; triangulation; sanitary risks. Representações Sociais e Triangulação: Uma Aplicação em Psicologia Social da SaúdeRESUMO -A relação entre o contexto social e a saúde representa um tema relevante para o desenvolvimento atual da psicologia social da saúde. A abordagem da representação social oferece uma estrutura para a análise do pensamento do senso comum sobre doença. Esta abordagem rompe com a tradição individualista que domina a análise social psicológica sobre os riscos sanitários.
