[Risk behavior due to alcohol consumption and quality of life in university students].

Objective: to measure the risky behavior (RB) to alcohol consumption, the quality of life (QOL) and the association between both.

[Measuring psychosocial stress at work in Spanish hospital's personnel. Psychometric properties of the Spanish version of Effort-Reward Imbalance model].

Background And Objective: Two main models are currently used to evaluate the psychosocial factors at work: the Demand-Control (or job strain) model developed by Karasek and the Effort-Reward Imbalance model, developed by Siegrist. A Spanish version of the first model has been validated, yet so far no validated Spanish version of the second model is available. The objective of this study was to explore the psychometric properties of the Spanish version of the Effort-Reward Imbalance model in terms of internal consistency, factorial validity, and discriminate validity.
