What are the main claims of the paper and how important are they?
The main claim is that polygrph is feasible as an instrument for testing the validity of the belief of psychotic patients regarding their delusions. Delusion by definition is an unshacable belief and we did not need the polygraph to prove this, but this is an accessory tool for the clinician and espcially the forensic psychiatrist to test how strongly the patient believe in his delusions. Second and more important is the feasiblity of adminstering the examination to acute psychotic patients. This is not trivial.
-
Are these claims novel? If not, please specify papers that weaken the claims to the originality of this one.
The claims are novel
-
Are the claims properly placed in the context of the previous literature?
Yes
-
Do the results support the claims? If not, what other evidence is required?
The resulsts are prelimiary and support the claims
-
If a protocol is provided, for example for a randomized controlled trial, are there any important deviations from it? If so, have the authors explained adequately why the deviations occurred?
The is not a randomized control study. Built in are questions that for each subject can test the vailidity of his responses.
-
Is the methodology valid? Does the paper offer enough details of its methodology that its experiments or its analyses could be reproduced?
yes
-
Would any other experiments or additional information improve the paper? How much better would the paper be if this extra work was done, and how difficult would such work be to do, or to provide?
This is a preliminary study. a group of malingerer can be added. also patients with simulation, dissimulation,m patients in partial remission regarding their delusions, complete remission
-
Is this paper outstanding in its discipline? (For example, would you like to see this work presented in a seminar at your hospital or university? Do you feel these results need to be incorporated in your next general lecture on the subject?) If yes, what makes it outstanding? If not, why not?
It is interesting because it adds to our ability to detects liars, exageation etc

The study is important, because it raises a practical issue - Is a polygraph test relevant for psychotic patients?
The issue is not new, but until now most researchers believed that no practical importance for a polygraph test in psychotic patients
The aim of the study was defined as absolutely correct
Our results contradict previous work on the subject and talk about the relevance of polygraph test in the evaluation of psychotic patients
The statistical technique is compatible with the circumstances of the study. This is not a comparison between the groups, but the analysis of clinical material content compared with the results of the polygraph test.
The method is compatible with the purpose of the study and is valid for examination of investigators claims, Of course, it is important to verify the data for reconsideration.
Study of a larger group and other research centers can verify the claim.
I see this work presented in a seminar in our hospital, the results may be incorporated in my lecture, if I give a lecture on this subject.
