Motivational Interviewing (MI) is an evidence-based behavior change intervention. The interactional change processes that make MI effective have been increasingly studied using observational coding schemes. We introduce an implementation of a software-supported MI coding scheme the Motivational Interviewing Treatment Integrity code (MITI) and discuss advantages for process researchers. Furthermore, we compared reliability of the software version with prior results of the paper version. A sample of 14 double-coded dyadic interactions showed good to excellent interrater reliabilities. We selected a second sample of 22 sessions to obtain convergent validity results of the software version: substantial correlations were obtained between the software instrument and the Rating Scales for the Assessment of Empathic Communication. Finally, we demonstrate how the software version can be used to test whether single code frequencies obtained by using intervals shorter than 20 min (i.e., 5 or 10 min) are accurate estimates of the respective code frequencies for the entire session (i.e., behavior slicing). Our results revealed that coding only a 10-min interval provides accurate estimates of the entire session. Our study demonstrates that the software implementation of the MITI is a reliable and valid instrument. We discuss advantages of the software version for process research in MI.

The transmission of electronic mail and static images on the Internet functions through simple computer telecommunication terminals running software. Practical methods for codec systems that process video coding in software have been discussed in order to use such terminals for audiovisual communications. The authors first discuss the advantages and problems when performing coding using software for audiovisual signals. They then propose a dynamic computational control strategy in order to provide software-driven video coding quickly and cheaply as a way to deal with these problems. Next the authors confirm the coding performance through experiments, and using the results they derive the relationship between the coding computational burden and the QOS level. Based on this relationship, the authors offer a video coding control strategy peculiar to software, in addition to providing a policy for creating software-driven audiovisual systems.
