The purpose of this investigation was to investigate the concurrent validity of the Life Orientation Test-Revised (LOT-R) (Scheier et al., 1994) and Optimism/Pessimism Scale (OPS) by administering each questionnaire to the same group of participants. The 154 participants (84 men and 70 women) were volunteer university students enrolled in physical activity classes at a southeastern university. The questionnaires were counterbalanced to reduce possible bias due to taking one questionnaire before taking the other. Due to recent suggestions concerning scoring mechanisms for the LOT-R (Dember et al.
Media richness theory argues that different media are more or less appropriate for different tasks. Social information processing theory (SIP) explains a motivation and method guiding such technology adoption. In light of these theories, and the field's lack of understanding of media effects on group development, this article investigates the development of two important group process factors ± cohesion development and process satisfaction ± in two different studies of groups supported by electronic meeting systems. Results indicate that initial levels of cohesion and process satisfaction differ depending on the medium (and its inherent richness) and, consistent with SIP, cohesion and process satisfaction increase over time in all types of electronic support, despite relative differences in media richness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
