Interesting, but here’s one of the comments:
This is a prime example of a cross-sectional study that is being reported as having a cause-effect relationship (an error of endogeny, or “correlation does not imply causation.”). We don’t actually know that helicopter parents produce incompetent children; perhaps incompetent children, through early life struggles, create more involved and worrisome parents? Further, we don’t know that involved parenting produces depression; maybe depression creates a need to feel worth or involvement in their children? This is a classic example of a reporter reading into a study’s results and drawing conclusions that can’t be supported by the methods.
