Trust in Distributed Groups
Overall research program objective: Understand interpersonal relations (trust) at a distance
Motivation• Paradox of trust in distributed groups• Competing theoretical explanations• Inadequacy of existing theory
Distributed Groups
Groups in which some or all of the members do not work in the same physical location
• 52% of large companies use geographically distributed teams (deLisser, 1999)
• Collaborative work in a virtual arrangement has been cited as a top workforce trend in the next 10 years (Kemske, 1998)
TrustTrust - willingness to be vulnerable based on
positive expectations of the intentions or behavior of others (Mayer, Davis & Schoorman, 1995; Rousseau, Sitkin, Burt & Camerer, 1998)
Cognitive trust - beliefs about reliability and dependability (McAllister, 1995)
Affective trust - beliefs about reciprocated care and concern (McAllister, 1995)
Overall program planStudy 1 - Lab experiment, test of existing
theory (Wilson, Straus & McEvily, 1999)
Study 2 - Field study, focuses on distributed groups in context, develops a broader theory of interpersonal relations at a distance
Common denominators: looking at trust over time in distributed groups
Study 1: Competing theoretical perspectives
Cues Filtered Out - Computer-mediated communication reduces social context cues and leads to depersonalization (Kiesler, Siegel & McGuire, 1984; Daft, Lengel & Trevino, 1987)
Social-identity Deindividuation - Group identity is the most salient cue computer-mediated groups have; this leads to social self-categorization (Lea & Spears, 1992)
Social Information Processing - All groups are motivated to develop social relationships. It takes longer in computer-mediated groups because there is less social information per message (Walther, 1992; 1995)

Study 1: Sample and Task
• 52, 3-person groups (participants randomly assigned to group, groups randomly assigned to condition)
• Each group met three times, with the following cycle of tasks: narrow down a list of stocks to 3 that members would research (together or separately) spend tokens on researched stocks (cooperating or defecting)

Conclusions
• Results support social information processing predictions (trust develops more slowly in computer mediated groups)
• Starting condition matters• Prescriptions for practice depend on the
nature of the group length of time
malleability of the task
Limitations
• Student teams lack a “shadow of the future” or structural assurance (which are likely to affect the development of trust in organizational groups)
Inadequacy of existing theories
• All of the theories about development in distributed groups are about media effects
• Distributed groups differ from co-located groups on more dimensions than the technology they use to communicate Distance Familiarity Face-to-face contact Identity
What we know about distanceThe original law of propinquity (Newcomb, 1956)
Physical proximity Frequency of interaction Similarity

Qualitative: Three teams: varying on distance, familiarity, amount of face-to-face contact
• interviewing all members of the teams once a month regarding expectations, trust, violations, attributions, and other team processes that might be affecting trust.
• attending all (formal) team meetings
What predicts trust between team members at month 3?

From HLM analyses:
Extras
Full 3-way longitudinal modelLevel 1 model - dyadic variables over time
(trust and communication)Level 2 model - variation among dyads within
a group (familiarity and distance)Level 3 model - variation between groups
(group identity)
Results from Level 1 analysis
• trust between team members is increasing over time (t = 42.46, p < .001)
• the amount of communication between team members has an effect on the development of trust over time (t = 19.31, p < .01)
Level 2 & 3: Intercepts as outcomes
• familiar dyads do start with higher levels of trust (t = 4.49, p < .001)
• trust between individual team members is marginally higher in groups with higher levels of group identity (t = 2.12, p < .10).
Level 2 & 3: slopes as outcomes
• Group identity does not influence the rate of trust development between individual members of the teams (t = 0.67, ns).
• Dyads who are familiar with each other at the outset have a slower rate of growth in trust development than dyads who are not familiar with each other (t = -2.98, p < .01).
