Two studies of male manual workers are described, in which eight scales relevant to the quality of working life are introduced and assessed. The scales build upon previous work, but are designed to remedy certain conceptual and operational deficiencies. They cover work involvement, intrinsic job motivation, higher order need strength, perceived intrinsic job characteristics, job satisfaction, life satisfaction, happiness, and self-rated anxiety. In addition, components of job satisfaction and life satisfaction, derived through cluster analyses, are also identified. The scales are shown to have good internal reliability and to be factorially separate. Comprehensive psychometric data are provided as a base-line for future applications.
