“…CFA has taken on a major role in scale development as it can greatly enhance the confidence in the structure and the psychometric properties of a new measure (Holbert & Stephenson, 2002;Noar, 2003). In CFA, it is possible to represent hypotheses about the factorial structure of constructs (Bollen, 1989).…”

“…All studies were part of a larger project dealing with trust in news media (Kohring & Matthes, 2004). In order to establish and empirically confirm a standardized concept of NFO, a confirmatory instead of an explorative approach-as is still common in many scale developments in the communication sciences (Holbert & Stephenson, 2002)-is needed. Thus, the data were analyzed by confirmatory factor analysis, which allows hypotheses about the structure of concepts to be represented.…”

The need for orientation is the most prominent contingent condition for agenda-setting effects. It provides a psychological explanation for why people engage in information seeking and why some people are susceptible to agenda-setting effects while others are not. The purpose of this paper is to present the development and empirical validation of a three-dimensional scale of need for orientation. Based on a review of previous measures, three dimensions of need for orientation are posited: The need for orientation towards issues, the need for orientation towards facts and the need for orientation towards journalistic evaluations. In a first step, the model is tested on a representative sample applying confirmatory factor analysis. After some modifications, the model is finally validated on another, independent sample. A series of studies demonstrate the psychometric properties of the measure and its construct validity with respect to related constructs. The theoretical utility of the construct and the measure of need for orientation are discussed.

“…Similar problems have been observed in political and health communication (see McLeod, Kosicki, & McLeod, 2002;Worden & Flynn, 2002). Despite calls for conceptual models to include media stimuli, psychological states (mediator variables), and media effects at the same time (Holbert & Stephenson, 2002McLeod, et al, 2002;O'Keefe, 2003), mediator variables generally receive short shrift in communication research.…”

The Mediated Moderation Model of Interactivity

This paper argues for enhanced consideration of third variables in interactivity research and proposes a "mediated moderation" model to bring increased sophistication to bear on the study of information technology effects. Interactivity, a central phenomenon in new media research, is an elusive concept that has enduringly intrigued and confused scholars. Extant conceptualizations have produced incomplete causal models and have generally ignored the effect of third variables. We conceptualize interactivity as technological attributes of mediated environments that enable reciprocal communication or information exchange, which afford interaction between communication technology and users, or between users through technology. Specifying roles for mediator and moderator variables, this paper proposes a model that incorporates interactive attributes, user perceptions (mediators such as perceived interactivity), individual differences (moderators such as Internet self-efficacy), and media effects measures to systematically examine the definition, process, and consequences of interactivity on users. Lastly, statistical procedures for testing mediated moderation are described.An enduring question and major inconsistency in interactivity research is how to best isolate the concept for systematic investigation. Various definitions and multi-dimensional models have been proposed but current approaches attempt to either mix structural characteristics of media systems, message exchanges, and user perceptions into a single multidimensional construct, or identify one of these factors as the central locus of interactivity (Sundar, 2004). Not surprisingly, the empirical research on interactivity has yielded scattered findings and has been unable to ascertain consistent patterns of effects on users. After three decades of analysis and investigation, we scarcely know what interactivity really is, let alone what MEDIA PSYCHOLOGY, 9,

“…Due to the dichotomous nature of the Goldberg response scales (yes/no), asymptotically distribution-free (ADF) estimation, which does not require rigid assumptions regarding population distributions, was preferred to maximum likelihood estimation (MacCallum et al 1996). Model fit was evaluated using the χ 2 test as an index of absolute fit, and several alternative indices that are less sensitive to sample size (Holbert and Stephenson 2002) Table 1 presents demographic and illicit drug use characteristics for the four current ecstasy using groups. There were no significant differences across groups for somatic, non-somatic and overall psychological distress scores, or in terms of gender distribution.…”

Are ecstasy users biased toward endorsing somatic mental health symptoms? Results from a general community sample

2010

Rationale: Whether the reported poorer mental health of ecstasy users is due to a bias in endorsement of somatic symptoms has been postulated, but rarely examined.Objectives: To investigate whether levels of ecstasy use were associated with differential probabilities of endorsing somatic mental health symptoms.Methods: Current ecstasy users aged 24-30 years (n = 316) were identified from a population-based Australian study. Measures included frequency of ecstasy, meth/amphetamine and cannabis use and the Goldberg anxiety/depression symptom scales.Results: Multiple indicator, multiple cause (MIMIC) models demonstrated no bias towards endorsing somatic symptoms with higher ecstasy use, both with and without adjustment for gender, cannabis and meth/amphetamine use. Conclusions:Other studies using alternate measures of mental health should adopt this approach to determine if there is a bias in the endorsement of somatic symptoms among ecstasy users.
