The meta-analysis suggests that strong fear appeals produce high levels of perceived severity and susceptibility, and are more persuasive than low or weak fear appeals. The results also indicate that fear appeals motivate adaptive danger control ac...
A meta-analysis was conducted to determine whether the relative magnitude of common factor and specific treatment effects was related to the classes of outcome domain (subjective well-being, symptoms, and life functioning) described in Howard, Lueger, Maling, and Martinovitch's 1993 phase model of psychotherapy. Effect sizes were calculated for 80...
This study provides an experimental test for the conclusions of the Allen and Preiss (1997) meta‐analysis that statistical evidence is more persuasive than narrative evidence. This investigation extends that finding to consider the case where a message combines statistical and narrative evidence to determine if a combination of evidence is more eff...
This study examines whether or not the subjective probability model accurately predicts the beliefs of an individual for circumstances of a single event with multiple causes. The mathematical model specified by the subjective probability model continues to provide some degree of prediction for beliefs prior to the exposure to a message. After expos...
This study investigates the internal dimensions of the Organizational Identification Questionnaire (OIQ). Results of factorial analytic tests of cross-sectional and longitudinal data indicate that the OIQ is unidimensional across organizations and time, but that only 12 of 25 items contribute meaningfully to the scale.
