    Opis:
    Many studies on the impact of psychosocial working conditions on health prove that psychosocial stress at work is an important risk factor endangering workers’ health. Thus it should be constantly monitored like other work hazards. The paper presents a newly developed instrument for stress monitoring called the Psychosocial Working Conditions Questionnaire (PWC). Its structure is based on Robert Karasek's model of job stress (Karasek, 1979; Karasek & Theorell, 1990). It consists of 3 main scales - Job Demands, Job Control, Social Support - and 2 additional scales adapted from the Occupational Stress Questionnaire (Elo, Leppanen, Lindstrom, & Ropponen, 1992), Well-Being and Desired Changes. The study of 8 occupational groups (bank and insurance specialists, middle medical personnel, construction workers, shop assistants, government and self-government administration officers, computer scientists, public transport drivers, teachers, N = 3,669) indicates that PWC has satisfactory psychometrics parameters. Norms for the 8 groups were developed.

    Opis:
    Aim. The objective of this study was to test the psychometric properties of selected scales, namely, Decision Latitude, Psychological Job Demand, Social Support and Job Insecurity, from the Polish version of Karasek’s 29-item Job Content Questionnaire (JCQ). Method. The study covered 2626 workers from a wide range of occupations. Estimation of internal consistency with Cronbach’s α, and both exploratory factor analysis (with principal axis method) and confirmatory factor analysis were the main statistical methods. Predictive validity was assessed by regressing the outcomes of JCQ scales on the outcomes of Goldberg and Williams’s General Health Questionnaire. Results. The internal consistency of the scales was satisfactory, ranging from .60 to .85. The 4-dimensional structure of the measured version was generally confirmed; the 4 dimensions being Decision Latitude; Psychological Job Demands and Job Insecurity merged into 1 factor; Co-workers’ Social Support; and Supervisors’ Social Support. Fit indexes for this model were satisfactory, it was also proved that this model predicted mental health. Conclusions. The Polish version of Karasek’s 29-item JCQ has satisfactory psychometric properties; it is a short, easy method for assessing psychosocial work conditions.

    Opis:
    The objectives of this study were to examine the agreement between 5 ergonomic risk assessment methods calculated on the basis of quantitative exposure measures and to examine the ability of the methods to correctly classify 4 at risk jobs. Surface electromyography and electrogoniometry were used to record the physical exposures of 87 sawmill workers performing 4 repetitive jobs. Five ergonomic risk assessment tools (rapid upper limb assessment [RULA], rapid entire body assessment [REBA], American conference of governmental industrial hygienist’s threshold limit value for mono-task hand work [ACGIH TLV], strain index [SI], and concise exposure index [OCRA]) were calculated. Dichotomization of risk to no risk and at risk resulted in high agreement between methods. Percentage of perfect agreement between methods when 3 levels of risk were considered was moderate and varied by job. Of the methods examined, the RULA and SI were best (correct classification rates of 99 and 97% respectively). The quantitative ACGIH-TLV for mono-task hand work and Borg scale were worst (misclassification rates of 86 and 28% respectively).

    Opis:
    An analytical design procedure to determine optimal noise hazard control strategies for industrial facilities is presented. Its objective is to determine a set of appropriate noise controls to eliminate or reduce noise levels so that workers’ daily noise exposure does not exceed a permissible level. From a given noise control budget, engineering controls will be firstly implemented, followed by administrative controls, and then the use of hearing protection devices. Six optimization models are developed and sequentially applied to select appropriate noise controls without exceeding the budget. Numerical examples are presented to demonstrate the application of the proposed design procedure.
