Conversion of an odds ratio (less than one / greater than one)

#1
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?

Less is more. Stay pure. Stay poor.

If you invert the value, you can get the outcome for the other exposure group, which would be positive.

How were the ORs calculated, contingency table or logistic regression? Also, were any other variables adjusted for in the calculation?

Thank you very much.

So this means the OR 0,73 life satisfaction transforms into 1/0,73=1,37 OR for low life satisfaction?

The mentioned OR comes from this study – page 284 - table 2 – last row „sexual abuse“:

Adverse Childhood Experiences (ACE) Within a Social Disadvantage Framework: Distinguishing Unique, Cumulative, and Moderated Contributions to Adult Mental Health

„How were the ORs calculated, contingency table or logistic regression? Also, were any other variables adjusted for in the calculation?“

Lots of variables were adjusted for:

„The second set of regressions examined the cumulative effects of the eight ACE items entered simultaneously, controlling for demographics and social disadvantage and revealing which ACE items affected mental health net of other experiences. The third set of regressions examined the contribution of each individual ACE item alone on mental health outcomes, again controlling for demographics and social disadvantage. The relative path coefficients of these two sets of regressions were then examined as a basis for the relative toxicity or stress load of that ACE on the three mental health outcomes.“
