Psychophysiological insomnia is associated with:

Choice A reason: Hot flashes can disrupt sleep, especially in menopausal women, but they are not the defining feature of psychophysiological insomnia. Choice B reason: Stress and anxiety are the primary causes of psychophysiological insomnia. This type of insomnia develops when worry and tension interfere with the ability to relax and initiate sleep. Clients often become preoccupied with their inability to sleep, which perpetuates the cycle. Choice C reason: Pain can cause secondary insomnia, but it is classified as insomnia due to a medical condition rather than psychophysiological insomnia. Choice D reason: Headaches may disturb sleep but are not the central mechanism of psychophysiological insomnia. The disorder is more directly linked to stress and anxiety.
