One study contains the information that sexually abused people have an odds ratio of 0.73 for the characteristic life satisfaction. So sexuelly abused people are less satisfied with their life than non-sexually abused people. Is it possible to convert the value 0.73 into an odds ratio with a value greater than one for the characteristic dissatisfaction with life? If so how is this done? Or is it necessary to have the data oft the study to calculate the new odds ratio?
