The health belief model (HBM) posits that messages will achieve optimal behavior change if they successfully target perceived barriers, benefits, self-efficacy, and threat. While the model seems to be an ideal explanatory framework for communication research, theoretical limitations have limited its use in the field. Notably, variable ordering is currently undefined in the HBM. Thus, it is uncl...

OBJECTIVE Cognitive behavior therapy (CBT) leads to a significant reduction in fatigue severity and impairment in patients with chronic fatigue syndrome (CFS). The purpose of the present study was to determine whether the effect of CBT for CFS on fatigue and impairment is mediated by a decrease in avoidance behavior and focusing on fatigue. METHODS For this purpose, we reanalyzed a randomized...

The mechanism of action responsible for hypnotherapy's effect in reducing hot flashes is not yet known. The purpose of this study was to examine the role of response expectancies as a potential mediator. Hypnotizability was also tested as an effect moderator. Data were collected from a sample of 172 postmenopausal women, who had been randomized to receive either a 5-week hypnosis intervention o...

This article provides a critical examination of telecommunications regulation in the EU and argues for the need for change along the lines of subsidiarity and mediation. This discussion is particularly timely, as the European Commission is working on a new telecommunications regulatory framework, with the lessons and failures of the past appearing more critical than ever. In this context, this ...

This study empirically establishes a link between medieval trade, agglomeration and contemporary regional development in ten European countries. It documents a statistically and economically significant positive relationship between prominent involvement in medieval trade and commercial activities and regional economic development today. Further empirical analyses show that medieval trade posit...

Previous studies on information disclosure have heavily relied on the justice theory to explain how users balance the benefits and privacy risks (e.g., privacy calculus) induced by the information disclosure behavior. However, the specific mechanism of privacy calculus (or the role of justice) and the boundary conditions under which the privacy calculus works have been rarely empirically invest...

The present study is aimed to examine the mediating effect of psychological capital in the relationship between organizational justice and organizational citizenship behavior. Data has been collected from a sample of 350 employees from multimedia organizations operating in Malaysia through personally administered questionnaires. The mediation effect has been tested using structural equation mod...

Mediation is said to occur when a causal effect of some variable X on an outcome Y is explained by some intervening variable M. The authors recommend that with small to moderate samples, bootstrap methods (B. Efron & R. Tibshirani, 1993) be used to assess mediation. Bootstrap tests are powerful because they detect that the sampling distribution of the mediated effect is skewed away from 0. They...

OBJECTIVE To examine the role of temperament (i.e., surgency/positive affect, negative affect, and effortful control) in the social behavior of pediatric brain tumor survivors and comparison classmates. METHODS Parent-, peer-, and self-report data were collected for 75 children after treatment for a brain tumor, and 67 comparison classmates. Tests of mediation and moderated mediation were run...

Dietary planning is supposed to mediate between intentions and dietary behaviors. However, if a person lacks self-efficacy, this mediation might fail. A cross-sectional study in Costa Rica and a longitudinal study in South Korea were designed to examine the moderating role of self-efficacy in the intention– planning–behavior relationship. Intentions, planning, self-efficacy, dietary behaviors, ...
