If you are referring to validity, do a principal components analysis.  Reliability use Cronbach's alpha.  Cross reference your results from PCA with Cluster Analysis.  I am a sas user so I only no the code for sas which is:\n\nproc factor data=females\nsimple\nmethod=prin\npriors=one\nmineigen=1\nscree\nrotate=varimax\nround\nflag=.5;\nvar rate1-rate10;\nrun;\n\nRobert DeVellis; Scale Development: Theory and Application 2nd edition.

BullDogg has a good point the ACS is run by drug companies and politicians. They only research useless and costly treatments. To see for yourself read the e-book I have linked to below, chapter 7 is very informative. Nut the whole thing is a must read. You will never want to donate to those organizations again. My dad died of cancer and if this information was used and widely available he would still be alive.

Clinical assay is determining the concentration of either a antigen or antibody or microorgannisms or drugs.\n\nIt is very useful in the diagnosis of diseases.

What do you mean? Are you talking about statistics  or about new treatment options for cancer?\n\nWith over 200 different types of cancer, stages and grades of tumor . . .  the question is a little vague.

I think you are really asking about the meaning of a prospective trial.  Both Retrospective (looking backward) and Prospective (looking forward) trials can be randomized and controlled. \n\nProspective trials generally offer more solid evidence than retrospective trials.  Randomization and controls help to validate the legitimacy of the findings.\n\nHope this helps.  Best wishes.

"Da Pool Stick" is clueless.  Here is a major quote about the cancer risks associated with aspartame.  This quote comes from the U.S. government's research journal "Environmental Health Perspectives", March 2006 issue.\n\n"The results of this mega-experiment indicate that APM (aspartame) is a multipotential carcinogenic agent, even at a daily dose of 20 mg/kg body weight, much less than the current acceptable daily intake.  On the basis of these results, a reevaluation of the present guidelines on the use and consumption of APM is urgent and cannot be delayed."\n\nThe FDA has serious conflicts of interest (primarily money from the pharmaceutical industry) that often cause its actions not to be in the best interest of the public.  We have seen the terribly negative effect of these conflicts (with potentially hundreds of thousands of unnecessary deaths from drug side-effects) with the recent 'fiasco's' over common drugs including: Hormone Replacement Therapy (Premarin), NSAIDs (especially Vioxx), Ritalin, and SSRIs (anti-depressants).\n\nHope you find this helpful.

Double blinding a study helps to determine the actual effect of the drug, or whatever is being tested.  If neither the participant or the investigator knows which treatment the participant is receiving, there will be less interference in the data due to placebo effects etc.\n\nThe investigator may treat the participant differently if he knows which treatment the participant is receiving.  Likewise, if the participant knows they are getting the active treatment, they may psychologically feel it is working better.
