Coping Strategies
• Problem-focused coping• Emotion-focused coping• Proactive coping
Copyright © Houghton Mifflin Company. All rights reserved. 14 | 33
Problem-Focused Coping
• In dealing with essential tasks, it is better to confront and control than to avoid.
• Why is it not always a beneficial approach?– Can be physiologically taxing– Can lead to development of an over-controlling,
stress-inducing Type A pattern of behavior
Copyright © Houghton Mifflin Company. All rights reserved. 14 | 34
Emotion-Focused Coping: Shutting Down
• One way to react to stress is by shutting down and trying to deny or suppress the unpleasant thoughts and feelings.
• Distraction can be an adaptive form of avoidance coping.
• Concealing one’s innermost thoughts and feelings can be physiologically taxing.
Copyright © Houghton Mifflin Company. All rights reserved. 14 | 35
Emotion-Focused Coping: Opening Up
• Two aspects to opening up as an emotional means for coping with stress:
– One must acknowledge and understand one’s emotional reactions to important events.
– One must express those inner feelings to themselves and others.
• Why might opening up be helpful?– Cathartic experience?– Helps to gain insight into the problem?
Copyright © Houghton Mifflin Company. All rights reserved. 14 | 36
Self-Focus: Getting Trappedvs. Getting Out
• Self-awareness theory revisited.• A self-perpetuating feedback loop can occur:
– Being in a bad mood triggers self-focus.– Self-focus in people with low self-esteem further
worsens the mood.
• Gender differences: Women brood and menact out.
