I am not surprised you disagree, Ron! Thats what makes us get along so well! I think you walked right into what I wanted to get across: Each of the variables you listed below can be measured, right? If something (a dependent or attribute variable) can be measured, then it has a number which can then be used to determine if the unique variable is significant , and this is the important part, I think, that when using a regression analysis, it takes into account all the other unique and not unique variables thought to be a contributor to the healing (increased functional activities, increased occupation). So, if one individual, has a history of any or most of these, then how does that effect your treatment versus if she had 30% relevant, or 10% relevant, etc... The more variables, the more chances for your results occuring because of poor internal validity (poor job controlling all the other variablesvariables) - and you dont know if it were treatment approach a or b or c or d or e.....or placebo. OK...I am going statistical here and trying to explain it..,.....but, if you can quantify something, you can study its relationship with other variables and outcomes. This is fun.

That's what makes us unique. And perhaps the greatest and uniqueness variable of all is the subjective feeling and experiences associated with injury, disease and illness. It is in fact that subjective experience of our patient's that makes being an OT so difficult. Regarding a list, here's a few: age, gender, marital status, employment history, race, religion, medical history, current medications, spiritual beliefs, family support, financial support, cognitive status, mental status, education, prior experience with OT, expectations, diet, sleep patterns, do they have regular bowel movements, etc. The list is truly endless!!
