Physicians must be free to use new unproven therapeutic measures if doing so offers hope for an improved outcome | Declaration of Helsinki |
Physician should obtain the patient's consent BUT if physician considers it essential to not obtain consent then the reason should be stated in the experimental protocol & assessed by the independent committee (IRB) | Declaration of Helsinki (Therapeutic Research) |
Physicians may combine clinical research with professional care only to the extent that the clinical research is justified by its expected therapeutic value | Declaration of Helsinki |
Written in 1966, Differentiated between therapeutic & non-therapeutic research | AMA Ethical Guidelines for Clinical Research |

Are a means for researchers to organize findings into a meaningful pattern | Theories |
Set of related statements that describe or explain a phenomena in a systematic way | Theory |
Can never be proven or confirmed | Theories |
Is a word, picture, or mental idea of a phenomena | Concept |
A general abstract explaination of the inter-relationship of concepts in a theory to be investigated | Theoretical Framework |
Phenomena are described or relationships between variables are examined | Descriptive (Non-experimental) |
Study of observing, counting, describing & classifying | Descriptive (Non-experimental) |
