Are there counterparts on the Left?

Encountered today in what passes for a conservative magazine today:

“Adolescents with very conservative parents are 16 to 17 percentage points more likely to be in good or excellent mental health compared to their peers with very liberal parents.” So concludes Jonathan Rothwell in a new study, “Parenting is the Key to Adolescent Mental Health,” sponsored by the Institute for Family Studies and Gallup. The crucial factor contributing to good mental health is clear discipline combined with parental love. Children need a warm authoritarian family culture. The problem among progressive parents is not affection. Liberal parents manifest parental love at only slightly lower levels than conservative parents. (The survey asked for responses, among other things, to the statement, “I hug or kiss my child every day.”) But liberals are significantly less likely to impose discipline than are parents who identify as conservative. (This assessment is based on responses to statements such as “I find it difficult to discipline my child” and “My child often gets their [sic] way when we have a conflict.”) Put simply, the liberal ideal of an affectionate permissive family culture is bad for children, whereas the old-fashioned view of authority is good.

And not just for children. In the twentieth century, the rise of the permissive family culture correlated with anxieties about “adolescent rebellion,” the purported cause of troubled relations between parents and teenage kids. Rothwell notes that survey data show that conservative parents enjoy the strongest relations with their adolescent children, while liberals suffer the worst. It’s interesting to note that parents who are “very liberal” as opposed to “liberal” have nearly as good relations with their adolescent children as do conservatives. In my estimation, this positive outcome stems from the fact that “very liberal” means adherence to doctrinaire progressivism, which has its own authoritarian character, as we see at universities. Ironically, the key to successful parenting by the “very liberal” is the progressive taboo: authority.

Would I be correct in assuming that the Left has equivalent studies extolling the scientifically verifiable superiority of its tribes?
