BBS and working alone The effects of a
self-monitoring package on the safe performance
of bus operators

• Olson Austin (2001)

3
Background

• Very few instances of self-monitoring in the
  safety literature
• Safety management for lone workers represents a
  serious logistical problem
• Self-observations often appear to be a weak
  treatment
• No studies have evaluated the impact of S-M alone
  on work performance
• This study was inspired by reading a report in
  Krauses 1998 book

4
Method

• Ppts
• 4 experienced bus operators
• Resulted from a behavioral safety assessment
• Previous efforts involved awards and penalties
• 25 bonus for avoiding crashes for a quarter
• 7 step progressive discipline system
• Private investigators for drivers w/complaints
• Yearly safety awards at a banquet
• Infrequent performance reviews by dispatch
  supervisors

5
Method (2)

• DVs
• Complete stop
• Stopping position
• 2 sec motionless
• Mirror checking
• Self-monitoring estimations
• Supervisor collected data
• Design
• Multiple baseline across behaviors, with
  supervisor ride-along probes
• Observers rode the bus wearing headphones one or
  more loops around campus

6
Independent Variables

• Kick-off meeting
• Intro to BBS and rationale for the process
• Intro to and rationale for s-m process
• Ldrs signed a form promising no punishment from
  data collection
• Self-monitoring
• Completed forms 2x each day
• Feedback
• Graphs based on self-monitoring data each day
• Supervisor prompts and observations
• Prompted drivers to s-m
• Rode on buses to conduct observations

7
IV Integrity

• Self-monitoring
• Counted s-m forms and calculated percentage
  completed
• Feedback
• Percentage of days each driver initialed the
  feedback graph
• Supervisor prompts
• Percentage of prompt recorded on supervisor
  recording form

Discussion

• S-M produced a small effect in this case
• Behaviors were continuous difficult to observe
  difficult to record
• Small effects can have cumulative significance
• E.g., 15 increase would result in 480 fewer at
  risk mirror checks each month (374,400 fewer for
  all drivers at the company, annually).
• Problem with comparing s-m data and experimental
  data in this case?
