Coding observational data: A software solution

The analysis of observational data, particularly from social interactions, is often made difficult by the process of transcribing the verbal and behavioral interactions, having observers code on the transcriptions, and then transferring those codes to a statistical analysis program. The advent of computer-aided coding schemes has, to some extent, eliminated this laborious and time-consuming process. However, existing programs may not fulfill the needs of all of the researchers interested in this methodology, and furthermore, the expense of current systems may put these tools out of reach for some. The Observational Data Coding System (ODCS) software package presented here is a flexible coding tool designed to make efficient the process of coding observational data. A control panel allows the researcher to customize the program and coding system to suit his or her research questions. A variety of media (including video, audio, image, and text) can be read directly into the Windows-based program; trained observers can then code a variety of factors via buttons on the screen while the file is playing. An example of using the program to analyze conversation is provided. ODCS is a flexible, free tool for the coding of observational data.
