Does the Absence of Fathers Cause ADHD?

In a controversial new book, Destructive Trends in Mental Health: The Well-Intentioned Path to Harm, the authors point out a study that showed ADHD (Attention Deficit Hyperactivity Disorder) might be related to a lack of a positive father figure. Rogers Wright and Nicholas Cummings, two liberal psychologists who were prominent leaders within the American Psychological Association, have seen first hand how the organization has omitted important research when it did not fit in with their liberal dogma.

In a study described in the book, kids with ADHD were paired with male therapists due to a noted absence of fathers in this child/adolecent population. The kids were given behavioral treatment with the therapists and special attention was paid to developing a positive attachment to the male figure. At the end of the treatment, only 11% of the boys and 2% of the girls had to remain on medication. The authors of this sudy suggested that social forces may be major contributors to ADHD. Among these social forces are: "the absence of positive father role models; the presence of a revolving door for negative male role models brought into the home; poor parenting; the need for order in the classroom when teachers are severely curtailed in meting out discipline; and a declining appreciation in our culture of what constitutes normal boy behavior." This study was never given much attention by the mental health community as the "solutions" were not politically correct at they emphasized the deficit of a male role model.

I wonder how this lack of positive role models and declining appreciation for normal boy behavior plays out with the shortage of male teachers in the classroom. Could male children be taking Ritalin as a substitute for their absence?
