Submit your critique of Lin et al. (2011) Music therapy and spinal surgery. Do the best you can with the type of research study you believe this represents. The key goals of this critique are to: -define the independent variable and dependent variables AND measurements and instruments being used -list the ways the study worked to promote Internal validity (efforts to make sure any relationship between the variables’ correlations had integrity; you could trust the measures reported the relationship) -list the ways the study worked to promote External validity (efforts to make sure any findings COULD be generalized back to similar populations from which the sample was drawn) -list threats to Internal and External validity (recruitment, music frequency, staff training, etc.)
