2974.3	Assessment
Research Question (Clear, unambiguous)	"What is the effect of household structure on risk behavior?"  Given the one reference under relevant literature is to a study of 2001 that looks at this issue, this is apparently meant to be a replication project.
Relevant Literature	The URL points to the literature review of a 2001 study that includes the current research question.  Obviously this is dated, but okay for a start.
Causal Interpretations (clear, all parts defined, mechanisms, controls, plausible)	Given the emphatic statement denying causality in the one study to which you refer, we would expect a bit more care in the causal statements here.  How does this data give you more leverage?  What controls must you consider to look at causality?  The casual statement of the obvious (household structure does or does not effect the outcome) is not insightful.
Data (variables, sample, comparison)	Add Health is fine, but why only Wave I?  That does not seem to make sense.
Research Value	A replication and possible extension has straightforward value.  The idea mentioned in the outline that it could help detect and prevent adolescent risk behavior does not make much sense.
Overall	This is a plausible study although the presentation here is shaky.
