The decision to write a forensic report is influenced both by the preferences of the client and by certain ethical, practical, and legal realities. A judge requesting a report may want as much comprehensive information as possible, while an attorney may prefer that no report be written if the conclusions do not strengthen the case. In general, the report should be limited to conclusions which the forensic psychologist is prepared to express with confidence in court and to defend during cross-examination. The report should focus on those topics of interest to the client; the extent of data collection will vary depending on whether present, past, or future circumstances or conditions are being addressed. Once the forensic psychologist has gained a good grasp of legal and behavioral issues surrounding the case and determined and evaluated the information needed to resolve them, he or she should express impressions and conclusions in a clear, relevant, and informative manner. 30 references.
