The Theory of Planned Behaviour (TPB) has received considerable attention in the literature. The present study is a quantitative integration and review of that research. From a database of 185 independent studies published up to the end of 1997, the TPB accounted for 27% and 39% of the variance in behaviour and intention, respectively. The perceived behavioural control (PBC) construct accounted for significant amounts of variance in intention and behaviour, independent of theory of reasoned action variables. When behaviour measures were self-reports, the TPB accounted for 11% more of the variance in behaviour than when behaviour measures were objective or observed (R2s = .31 and .21, respectively). Attitude, subjective norm and PBC account for significantly more of the variance in individuals' desires than intentions or self-predictions, but intentions and self-predictions were better predictors of behaviour. The subjective norm construct is generally found to be a weak predictor of intentions. This is partly attributable to a combination of poor measurement and the need for expansion of the normative component. The discussion focuses on ways in which current TPB research can be taken forward in the light of the present review.

Efficacy of the Theory of Planned Behaviour: a meta-analytic review.

Purpose. To review applications of Ajzen's theory of planned behavior in the domain of health and to verify the efficiency of the theory to explain and predict health-related behaviors. Methods. Most material has been drawn from Current Contents (Social and Behavioral Sciences and Clinical Medicine) from 1985 to date, together with all peer-reviewed articles cited in the publications thus identified. Findings. The results indicated that the theory performs very well for the explanation of intention; an averaged R2 of .41 was observed. Attitude toward the action and perceived behavioral control were most often the significant variables responsible for this explained variation in intention. The prediction of behavior yielded an averaged R2 of .34. Intention remained the most important predictor, but in half of the studies reviewed perceived behavioral control significantly added to the prediction. Conclusions. The efficiency of the model seems to be quite good for explaining intention, perceived be...

The theory of planned behavior: a review of its applications to health-related behaviors.

Composition models specify the functional relationships among phenomena or constructs at different levels of analysis (e.g., individual level, team level, organizational level) that reference essentially the same content but that are qualitatively different at different levels (M. T. Hannan, 1971; K. H. Roberts, C. L. Hulin, & D. M. Rousseau, 1978; D. M. Rousseau, 1985). Specifying adequate composition models is a critical component of good multilevel research. A typology of composition models is proposed to provide a framework for organizing, evaluating, and developing constructs and theories in multilevel research. Five basic forms of composition are described and illustrated. Implications of the typology are discussed.

This study examined differences between union and non-union construction workers in terms of safety performance and of demographic, employment, and sociopsychological factors related to safety performance. Data were collected by questionnaire in a larger study on construction workers' safety practices among 384 workers employed at nine nonresidential construction sites in the Baltimore metropolitan area. Union and nonunion construction workers differed in terms of safety performance and certain factors related to safety performance. Higher safety performance scores among union workers were, however, related to the fact that union members were older than nonunion members. Moreover, other differences were related to elements over which unions have more control. Findings revealed the need of special attention of the nonunion youngest members, and of additional evaluation of the actual and potential role played by unions in occupational safety.

Safety performance among union and nonunion workers in the construction industry.

Construction workers' safety practices were studied in relation to individual and situational factors. The study included a survey among 384 workers, 88 foremen, and 9 superintendents employed at nine nonresidential construction sites as well as one-time observations of safety practices at each site. Most workers displayed a high compliance with safety rules. Attitude toward safety performance and age were the most powerful predictors of safety performance. No relationship was found between workers' attitude and exposure to safety training or safety meetings. Nor was any relationship seen between workers' knowledge of safety performance and safety interventions. Findings suggested further consideration of the training needs of younger workers and foremen and evaluation of safety interventions. Language: en
