Intrinsic motivation has been reported to be one of the strongest determinants of exercise adherence. The role of competition in exergames was studied to determine the ways to increase intrinsic motivation. We tested the competitive exercise setting as a contextual factor, and competitiveness as individual characteristic, to investigate their effect on intrinsic motivation using psychological, ...

Objectives There have been recent developments in statistical methods for assessing the mechanisms through which a complex intervention acts, with particular applications in mental health trials. This literature has focused on causal mediation analysis, which differs from statistical mediation analysis by its explicit acknowledgement and exposition of the necessary assumptions, particularly tha...

In this paper we address the problem of interoperation at a semantic level. We assume that emerging standards will solve most of the syntactic infrastructure problems that exist today. However, interoperation has to deal with sources from diiering domains, and their semantic diierences. We present mediation as the principal means to resolve problems of semantic interoperation. Since the number ...

An essential goal of program evaluation and scientific research is the investigation of causal mechanisms. Over the past several decades, causal mediation analysis has been used in medical and social sciences to decompose the treatment effect into the natural direct and indirect effects. However, all of the existing mediation analysis methods rely on parametric modeling assumptions in one way o...

This paper will explore if and how psychological strain plays a mediator role between the learning climate and job performance in a group of health workers. Although the relationship between learning climate and job performance has already been explored in the international literature, the role of psychological strain, which may hamper or deepen this relationship, has yet to be investigated. Th...

OBJECTIVES We draw on cognitive discrepancy theory to hypothesize and test a pathway from poor health to loneliness in later life. We hypothesize that poor health will have a negative influence on social participation and social resources, and these factors will mediate between health and loneliness. We hypothesize that rural environments will amplify any difficulties associated with social par...

Narrative Mediation is a new approach to mediation that was spurned by Narrative Family Therapy, developed in the mid-1980s by Michael White and David Epston, in Australia. It came out of their interest in post-modernism and social constructionism, in examining the making of meaning through the filter of language and the subjective interpretation of “facts”. While Narrative Therapy has become r...
