A survey of information gathering and information generating activities of 800 clinical psychologists and 378 persons in related fields was made. Two information needs of clinicians were noted: specific information related to their functioning and an information system suited to them. Of those queried, 59% reported that their meetings had contributed important background material. Journal articles (53%) and books or book chapters (43%) were the publications read most frequently. Of criticisms made, 11% were of journals; 10% of the suggestions made referred to journals. Requests were made for more audiovisual aids. Of information contacts made with persons during a day 22% of the contacts were with a clinical psychologist and 10% with a psychiatrist. Most of the information exchanges concerned a patient. A majority of respondents (69%) indicated that they had changed therapy during the year because of information received (28% because of journal articles, 15% because of information received at a convention, and 6% because of contact with another professional person). The most read journal was "The Journal of Consulting Psychology." Contrary to the stereotype that clinical psychologists do not write, 65% of 368 clinicians indicated that they had published. (MF)
