(1975) believes that quality is unique and should not be limited to a

sensory description. He suggested also examining affective and

evaluative qualities of the experience. Sensory qualities include

temporal, spatial, pressure, and thermal aspects. Affective qualities

include tension, fear, and autonomic properties. Evaluative qualities

involve the overall intensity of the experience, from annoying to

unbearable (Melzak, 1975).

 Other methods of defining pain expression involve observation by the

 investigator of overt behaviors such as restlessness, grimacing,

 groaning, and medication usage. Behaviors such as blood pressure,

 pulse, EMG readings, and galvanic skin response are also used to define

 pain expression.

 The instrument I used to measure pain expression was the McGill Pain

 Index. This self-report technique developed by Melzak (1975) measures

 the sensory, affective, and evaluative qualities of the pain experience.


 Hypotheses and Research Questions


 I hypothesized that personality type is associated with pain

expression, and that coping styles are associated with responses on the

McGill Pain Questionnaire.

 To test these hypotheses, I addressed the following research

questions: Is personality type associated with a particular type of

pain response? That is, is type associated with sensory, affective, or

evaluative responses? Additionally, is coping style associated with

pain response? If so, in what direction?
