“We speculate that patients with a chronic illness…have a good idea of their typical pain and fatigue levels. Given the difficulty of recalling many previous days, as in the case of the 28-day reporting period, patients may refer to these beliefs, which provide a reasonably good estimate of average symptom levels. However, when asked to construct a rating to represent the past 7 days, patients may attempt to retrieve some memories from the week, which are subject to the distortion of the cognitive heuristics mentioned earlier (e.g., peak effect), thereby decreasing accuracy.”
