A multiple option observation system for experimental studies: MOOSES

The purpose of this article is to outline the development of the Multiple Option Observation System for Experimental Studies (MOOSES), a flexible data collection package for applied behavioral research. Several data collection options are available to users of MOOSES. Event-based recording, interaction-based recording, duration recording, and interval recording are available to the users and can be used individually or together, depending upon the research question. The collection program can incorporate any of the keys on the keyboard. Function keys on the top or side are used for toggle (duration states) type data collection. Types of analysis include frequency and duration of discrete events, frequency of general behavior states, frequency and duration of events within behavioral states, percent interval analysis, sequential analysis, and interobserver agreement. Data obtained from MOOSES is easily incorporated with other data for further statistical analysis with standard statistical packages or popular spreadsheet programs. Applications of MOOSES and its uses in social interaction research are presented. Comparisons with other similar systems are provided.
