  1. The role of Research in OP

  2. Experiments OPERATIONAL DEFINITIONS: These help clarify meaning at EVENT level Symbolic Level: With Control: Can say I.V. caused Δ in D.V. Event Level:

  3. Research helps teach us the limits of the truth of statements. “Expert’s are those who know the limits of truth of statements.” O.B. overgeneralizations are easily made. e.g. Impact of Specific goals depends on culture: • if expect to participate in goal setting, need mutually agreed goals • Collectivist culture group goal over individual • “face-saving” cultures specific goals may lead to loss of face e.g. Increasing salary will motivate people to work more hours. Not always so. (Mexican study)

  4. Experimental Techniques Correlational Techniques Observational Techniques Control • Usually there is less control as go from lab experiment to field experiment to correlational research to observational/participatory research. However, can get richer, wider scope information.

  5. Research in O.P. Basics: • Hypothesis • Reliability • Validity

  6. Observational Techniques • Systematic and objective • Case studies • Participant Observation • Direct Observation Correlational Techniques Experimental Techniques • Issues e.g. Sampling Hawthorn effects Ethics

  7. Stress, Coping and Health • A reaction to environmental demands • Stressors versus stress

  8. Classification of Stressors by Complexity Biological Psychological Interpersonal Socio-cultural

  9. A Definition of Stress Stress is the nonspecific response of the body to any demand placed upon it. (Hans Selye) Reaction: Flight, flight or freeze A mobilization to action

  10. Reaction: Flight, flight or freeze mobilization to action

  11. Ulcers in “Executive Monkeys” Reacting to Stress: Selye’s three major stages: • Alarm reaction: defensive forces are mobilized • Resistance stage: body adapts to stressors • Exhaustion: stressors negates body’s coping mechanisms.

  12. Reacting to Stress: Selye’s three major stages: • Alarm reaction: defensive forces are mobilized • Resistance stage: body adapts to stressors • Exhaustion: stressors negates body’s coping mechanisms.

Minor violations of the law 11 Total score for 12 months:____________ Note: The more change you have, the more likely you are to get sick. Of those people with over 300 Life Change Units for the past year, almost 90% get sick in the near future; with 150 to 299 Life Change Units, about 50% get sick in the near future, and with less than 150 Life Change Units, only about 30% get sick in the near future. *See Holmes & Rahe: Journal of Psychosomatic Research, 11:213, 1967.

  15. Dealing with Stress: The organizational/ergonomic approach (eliminating or reducing unnecessary stressors) The Individual Approach (living in an imperfect world)

  17. Are you under the right amount of stress Too much (or too little) challenge can make you sick.

  18. Are you under the right amount of stress? Stress and Performance: The Inverted U

  19. “Cooper and Marshall Model” “Who is liable for stress on the job?” “Any company, unless it learn to monitor, diagnose and treat a stressful situation before it goes to court.—and document these activities.”

  20. Cooper Marshall Model:

  21. Role conflict • Interrole conflict • Intrarole conflict • Role ambiguity

  22. Work-Nonwork Stressors(McShane) • Time-based conflict • Strain-based conflict • Role Behaviour conflict Note: Canadian Statistics on work overload
