What they found came as no surprise and, unfortunately, fits with the classic "blame mom" approach to problematic kids (which, I think is an oversimplification of what's really going on). Basically, a mom that is distressed, intrusive or depressed herself is more likely to have a child that has problems eating, sleeping, or attaching. The authors did a really great job looking at different aspects of the mother-child-family dynamics and came to a few really great conclusions about what causes what, and how to move forward. Rather than go through it, I had a few ideas that I wanted to share
1) One of the findings was that there was no direct correlation between what kinds of distress mom had (depression, anxiety, family tension) and the kinds of symptoms kids had. Just a blanket statement that a mom in trouble has a kid that reflects it. It just goes to show that children demonstrate their own distress to problematic situations in unique ways. This points to the possibility that there is something in-born to the way a person deals with stress: one person can over-eat, while another will isolate. Moreover, its intriguing that these kinds of responses could have their origins in early childhood (0-3 years of age).
2) Of the kinds of diagnoses given to the kids in this study, at least half could be considered more biological than psychological. One normally doesn't consider a feeding disorder a psychiatric symptom, but when you work with kids, you see that they express distress using whatever tools they have. As such a feeding or a sleeping disorder, though considered physiological can represent distress in the family unit (or specifically mother-child unit). Interestingly, when looking at research relating to resilience factors in adults, studies on the biological markers of stress and resilience make up the bulk of what's examined. For example, I recently read an article talking about levels of levels of a neuro-hormone called NPY (Neuropeptide-Y) in veterans (Morgan, 2000). On its own, NPY is normally a marker for satiety. Its just interesting that it can also be found in relation to psychological stressors. All of this is to say that resilience or vulnerability can be found in physiology in addition to psychology, and that maybe the two things aren't so different after all.
3) Though the authors didn't talk about this directly, a distressed mother is actually something different than a distressed person. Both can co-exist (i.e. a person can have depression and anxiety independent of her being a mom), but a distressed mom might be distressed for other things more related to family structure and her own upbringing than something inherent to her. One thing they did talk about was how fathers play a buffering role with maternal distress, but they didn't go into much detail with this.
4) This study did a very good job of answering what happens when a mother is distressed, but not such a good one of answering how or why it happens. In thought number two I tried to address how: biological/physiological changes happen in the child in relation to the mother's distress ultimately causing a reflexive distress in the child that physicians label as dysfunction. I think the question of why is a lot more interesting. If we look at what the kids are doing as problems and label them as "disorders" we don't see them as adaptations to environmental problems. In other words, the way a child manifests a set of symptoms may actually be beneficial to him or her. If mom is anxious by nature, a baby is going to manifest behavior where mom will be even MORE anxious about taking care of the baby. If familial emotional resources are limited, the baby will do its best to get the most it can. This makes a lot of sense until resources run out. Unfortunately, that's when thing fall apart for everyone. Up until then, baby gets what it needs even at the expense of mom.
5) Given the fact that we can look at the "problems" above as limitations in resources, one way to modify the outcome is to improve the emotional resources of the parent-child relationship. Answering that question is going to take some time and effort.
Interesting stuff.
