This study demonstrated the effectiveness of a computer-delivered smoking cessation program for the worksite. 58 VA Medical Center employees were randomly assigned to a computer group (computerized nicotine fading and stop-smoking contest) or a contest-only group. In comparison with the contest-only group, the computer group had nonsignificantly higher abstinence rates across follow-up, had marginally lower CO levels at the 3- and 6-month follow-ups, and smoked cigarettes with lower nicotine levels at the 10-day and 6-month follow-ups.

The Group Development Process Analysis Measures were designed to facilitate the study of development in small groups. The measures include three scales for the process analysis of verbal content and style dimensions, a set of speech behavior codes, and a sociometric test for the identification of emergent leaders.

The process analysis scales are (a) the Hostility/Support Scale; (b) the Experiencing Scales (Klein, Mathieu-Coughlan, & Kiesler, 1986) adapted for use in the study of group psychotherapy; and (c) the Normative Organizational/Personal Exploration (NO/PE) Scale, which is used to rate units created by the Topic-Oriented Group Focus Unitizing Procedure. The Speech Behavior Coding System includes measures for length of statement, who is speaking, who is spoken to, and how frequently the group members refer to themselves as "we."The process of development in small groups has been studied conceptually for about 50 years.
