The Health Belief Model, social learning theory (recently relabelled social cognitive theory), self-efficacy, and locus of control have all been applied with varying success to problems of explaining, predicting, and influencing behavior. Yet, there is conceptual confusion among researchers and practitioners about the interrelationships of these theories and variables. This article attempts to show how these explanatory factors may be related, and in so doing, posits a revised explanatory model which incorporates self-efficacy into the Health Belief Model. Specifically, self-efficacy is proposed as a separate independent variable along with the traditional health belief variables of perceived susceptibility, severity, benefits, and barriers. Incentive to behave (health motivation) is also a component of the model. Locus of control is not included explicitly because it is believed to be incorporated within other elements of the model. It is predicted that the new formulation will more fully account for health-related behavior than did earlier formulations, and will suggest more effective behavioral interventions than have hitherto been available to health educators.

Social Learning Theory and the Health Belief Model

This article describes a 2-systems model that explains social behavior as a joint function of reflective and impulsive processes. In particular, it is assumed that social behavior is controlled by 2 interacting systems that follow different operating principles. The reflective system generates behavioral decisions that are based on knowledge about facts and values, whereas the impulsive system elicits behavior through associative links and motivational orientations. The proposed model describes how the 2 systems interact at various stages of processing, and how their outputs may determine behavior in a synergistic or antagonistic fashion. It extends previous models by integrating motivational components that allow more precise predictions of behavior. The implications of this reflective–impulsive model are applied to various phenomena from social psychology and beyond. Extending previous dual-process accounts, this model is not limited to specific domains of mental functioning and attempts to integrate cognitive, motivational, and behavioral mechanisms.

Reflective and Impulsive Determinants of Social Behavior

A central tenet of economics is that individuals respond to incentives. For psychologists and sociologists, in contrast, rewards and punishments are often counterproductive, because they undermine "intrinsic motivation". We reconcile these two views, showing how performance incentives offered by an informed principal (manager, teacher, parent) can adversely impact an agent's (worker, child) perception of the task, or of his own abilities. Incentives are then only weak reinforcers in the short run, and negative reinforcers in the long run. We also study the effects of empowerment, help and excuses on motivation, as well as situations of ego bashing reflecting a battle for dominance within a relationship.

Intrinsic and Extrinsic Motivation

Impression management, the process by which people control the impressions others form of them, plays an important role in interpersonal behavior. This article presents a 2-component model within which the literature regarding impression management is reviewed. This model conceptualizes impression management as being composed of 2 discrete processes. The 1st involves impression motivation ― the degree to which people are motivated to control how others see them. The 2nd component involves impression construction. The 2-component model provides coherence to the literature in the area, address controversial issues, and supplies a framework for future research regarding impression management

Impression management: A literature review and two-component model.

An apparatus for cleaning and sterilizing objects, such as pharmaceutical caps, plugs and the like includes an autoclave chamber and a cleaning device having a cleaning drum mounted for a free rotation on a frame. The frame runs on rollers and can be moved in and out of the autoclave chamber. The cleaning drum has a hollow shaft provided within the drum with spray nozzles and mounted axially in line with a hollow drive shaft passing through one sidewall of the autoclave chamber free to turn and sealed. The drum shaft and the drive shaft may be coupled together by a coupling device. The frame may be released from the drum introduced into the autoclave chamber so that it is not located during the cleaning process in the autoclave chamber and thus will not constitute an additional source of contamination.
