A cross-sectional sample of adults completed an extensive set of cognitive tasks and a set of questionnaires measuring depressive aect, memory complaint, and other variables. During an interview about their prescribed medications, the participants also reported whether they were having problems remembering to take the medication as prescribed (an everyday prospective memory problem). Their medication adherence at home was then monitored for one month using pill bottles which microelectronic caps. Cognitive tasks correlated with memory complaints, as measured by the Memory Functioning Questionnaire, but not with problems in remembering to take medications. The highest correlations were with a free recall task. Conversely, reported problems with medication adherence during the interview had good predictive validity for subsequent adherence problems, but not for cognitive tasks, including a measure of prospective memory. Depressive aect was related to both the questionnaire and the interview complaints about medication adherence, but a structural equation model showed that the relationships of cognition and medication adherence to the dierent memory complaints were independent of depressive aect. The results are interpreted in terms of a behavioural speci®city hypothesis, which states that adults' self-reports of memory problems are valid when they focus directly on speci®c memory-related behaviours in everyday contexts.
