Why is it important to have a patient's impressions?
Obviously if a patient feels better, that's great. So in one sense, a patient's impressions are extremely important--the goal of therapy is, after all, to restore her to mental and emotional well-being. But for the purposes of determining which treatments are most effective in which situations, there are several problems with a patient's own impressions of her progress. The first is simply that people in distress tend to get better. This is known as regression to the mean, or average, and it's when people have a tendency to move toward an average level of functioning or happiness from whatever state they are in. If you're really happy, you're most likely to get sadder, and if you're really sad, you're most likely to get happier. People spend most of their time feeling average, so moods that are above or below average are likely to return to this average. Since people usually enter treatment because they're feeling especially bad, they're likely to get better over time not because of anything the therapist is doing, but simply because they're regressing to the mean.
