Measure Impairment and Criminal Responsibility As it Relates to the Legal Standard
The R-CRAS provides the forensic psychologist or psychiatrist with an empirically based approach to evaluating criminal responsibility, allowing you to quantify impairment at the time of the crime, to relate impairment to the appropriate legal standard, and to render an expert opinion with respect to that legal standard.
Features and benefits
- Part I establishes the degree of impairment on psychological variables significant to the determination of insanity.
- Part II aids in rendering an accurate opinion on criminal responsibility with the ALI standard and includes experimental decision models for guilty-but-mentally-ill and M’Naghten standards.
- Average alpha coefficient of the R-CRAS summary scales is .60. The mean reliability coefficient for individual variables is .58, with each variable achieving significance.
- Overall percentage of agreement for the decision variables is 91% with an average kappa coefficient of .81.
- Validation studies indicate a high level of accuracy for distinguishing sane and insane individuals.
