Factor loadings, communalities (h²), and percent variance for principal axis factoring extraction on HRA items from TRACK II (N = 96)

Items	Factor loading	h2
1. During the past week: You were thinking about HIV infection/AIDS and your health, and because of that you had trouble sleeping—either getting to sleep or sleeping through the whole night.	0.84	0.71
2. During the past week: You were thinking about HIV infection/AIDS and your health, and because of that you had no appetite, or felt like eating very little.	0.91	0.82
3. During the past week: You were thinking about HIV infection/AIDS and your health, and because of that you had no desire to go out and do any social activities with other people.	0.82	0.67
4. During the past week: You were thinking about HIV infection/AIDS and your health, and because of that you had trouble concentrating at school or work because of worrying about your health.	0.92	0.85
Percent variance	76.26

Written or read scale instructions: Sometimes worrying about your health can really affect other areas of your life. For example, if you are very concerned about your health, you might have trouble getting to sleep at night, or you might wake up in the middle of the night and be unable to stop worrying. The following questions help us find out which areas of your life have been affected by your worrying during the past week. To answer these questions ask yourself, “During the past week, how often has thinking about HIV infection/AIDS and my health affected this area of my life?” Inter-item correlations are as follows: r₁₂ = 0.76; r₁₃ = 0.66; r₁₄ = 0.81; r₂₃ = 0.77; r₂₄ = 0.82; r₃₄ = 0.75.
