In recent years, organizations and businesses have increasingly used groups to
make decisions across a wide variety of settings. This trend has led to a need to make
group performance more accurate and effective. Despite the increased research relating to group performance in recent years, there is still incomplete understanding of the
factors leading to effective group development and group decision making . Only in recent times have researchers begun to explore the relationship between self-efficacy and group performance as a possible a factor leading to effective group performance. Current
understandings of group performance largely focus on the collective beliefs and views of
the ability -of the group to perform a specific task. In addition, instruments that were
developed to measure this relationship were also based on the aggregation of individual
group members to create a group average score. This conception, however, does not take
into · account individuals' beliefs and views of their ability to perform in group settings.
Recently researchers have begun to develop instruments that are more sensitive to the
relationship between individual self-efficacy in groups and group performance. In this
study, group performance will be analyzed in terms of individuals' perceptions of their
effectiveness in groups in contrast to groups' perceptions of their potency. Furthermore,
this study will examine the role of the individual group member in group performance.
Finally, this study will also examine the effect of task competence and of the group
development variables of forming and feedback on group decision making.
In preparation for the actual research study, this thesis will discuss the
background literature on self-efficacy and its relationship to group performance and
group development, and provide information about the current state of research on self-
efficacy in group performance (i.e., definition, conceptualization, and assessment). It
will examine current instruments for assessing the relationship between self-efficacy and
group performance and utilize a new instrument for assessing this relationship. It will
provide background literature review that led to a new conceptualization of individual
self-efficacy about group performance and differentiate this concept from current
research of self-efficacy in group performance. A method section will be provided,
which includes the design of the study, participation, procedure, and
measurements. Finally, the results section will detail the analysis of this study followed
by a discussion in which the author will explore implications of the research findings for
practitioners, the limitations of this study, and suggestions for future researchers.
