Ex. 7.1 The matrix below shows the correlations between ratings on nine statements about pain made by 123 people suffering from extreme pain. Each statement was scored on a scale from 1 to 6, ranging from agreement to disagreement. The nine pain statements were as follows: 1. Whether or not I am in pain in the future depends on the skills of the doctors. 2. Whenever I am in pain, it is usually because of something I have done or not done. 3. Whether or not I am in pain depends on what the doctors do for me. 4. I cannot get any help for my pain unless I go to seek medical advice. 5. When I am in pain, I know that it is because I have not been taking proper exercise or eating the right food. 6. People's pain results from their own carelessness. 7. I am directly responsible for my pain, 8. relief from pain is chiefly controlled by the doctors. 9. People who are never in pain are just plain lucky. 1.00 -0.04 1.00 0.61 -0.07 1.00 0.45 -0.12 0.59 1.00 0.03 0.49 0.03 -0.08 1.00 -0.29 0.43 -0.13-0.21 0.47 1.00 -0.30 0.30-0.24 -0.19 0.41 0.6 1.00 0.45 -0.31 0.59 0.63 -0.14 -0.13-0.26 1.00 0.30 -0.17 0.32 0.37 -0.24 -0.15-0.29 0.40 1.00 Fit a correlated two-factor model in which questions 1,3,4, and 8 are assumed to be indicators of the latent variable Doctor's Responsibility and questions 2,5, 6, and 7 are assumed to be indicators of the latent variable Patient's Responsibility.
