No. These stats are reported by scientists who did interviews with thousands of women who had lived through communism, and thousands born after it ended (their daughters)  and compared the results.
It didn't change as much for the older women. But there has been a notable decline in equality for the next generation (now in their 20s and 30s) and a resulting significant decline in sexual satisfaction levels. Interestingly the younger generation reports that their mothers keep trying to advise them on how to have more fulfilling love lives and they keep responding :"that's just not possible to do anymore".
One thing the communists had done right was to teach men from the start that women are their equals in every way. That's not entirely universal of course. China had and has a far more patriarchal communism. But it was true in the East Bloc.
The Soviet approach to socialism was fataly flawed in many ways. But they did do some things better.
