Psychosocial job characteristics and smoking cessation: a prospective cohort study using the Demand-Control-Support and Effort-Reward Imbalance job stress models.

Introduction: A prospective cohort study was conducted to examine the effects of psychosocial job characteristics on smoking cessation. Previous studies have failed to indicate consistently that psychosocial job characteristics predicted smoking cessation. Using the Demand-Control-Support (DCS) and Effort-Reward Imbalance (ERI) models simultaneously, we assessed psychosocial job characteristics more comprehensively than did previous researchers.

Psychosocial job characteristics and insomnia: a prospective cohort study using the Demand-Control-Support (DCS) and Effort-Reward Imbalance (ERI) job stress models.

Objective: To examine the prospective effects of psychosocial job characteristics evaluated with the Demand-Control-Support (DCS) and Effort-Reward Imbalance (ERI) models on insomnia.

Methods: A prospective cohort study with a two-year observation was performed. The subjects were 1022 middle-aged (>or= 39 years) Japanese workers.

Association between psychosocial job characteristics and insomnia: an investigation using two relevant job stress models--the demand-control-support (DCS) model and the effort-reward imbalance (ERI) model.

Background And Purpose: The details of risky psychosocial job characteristics related to insomnia are unclear, although potential relationships between the two have been suggested. The study objective was to clarify these relationships by using the demand-control-support (DCS) model and the effort-reward imbalance (ERI) model.

Patients And Methods: A cross-sectional questionnaire survey was conducted with 1081 middle-aged (39 years and older) workers in a corporate group of electric products in Osaka, Japan.
