How does the tetrachoric compare to these?

> Hello,
> Can Spearman's rho be used to measure of the degree of association between two binary variables ?
> I was wondering if Spearman's rho could be adequate  because I have used the phi coefficient to quantify association among several  binary variables and the results are identifical compared with Spearman's rho coefficient .
