Which you should interpret depends on what your question is....
Given that you have run this regression hierarchically, it appears that
you have three questions, which, not surprisingly, get three different
answers.
Each equation corresponds to a question thus
Question 1: Does SES relate to parent involvement? Answer: Yes
Question 2: How do SES and child functioning relate to parent
involvement,
when controlling for each other? Answer: Child functioning is
signficantly related,
SES is not
Question 3: (you get the idea)
This analysis raises further questions. which you may have answered
elsewhere in your paper or analyses: e.g. How do the IVs relate to each
other? Should you include 2 measures of child functioning and 2 of
support, or should you somehow reduce these? etc.

Hi. I just posted a question on h. regression. Maybe it would
be useful to provide some specifics of my analysis. My DV is
a measure of parent involvement in the education of their disabled
child. I actually enter only 3 groups of IVs, not 4. My DVs were
grouped and entered in the analyses thusly:
1. a measure of family SES;
2. 2 measures of child functioning; and
3. 2 measures of social support (1 family support, 1 school support).
In equation 1 -- SES is highly significant.
In equation 2 --SES significance dropped by ns (.156) and the child
functioning measures are
both significant at the .05 level.
In equation 3 -- SES and the child functioning measures become
insignificant and the 2 newly
measures both are highly significant at the .01 level or
better. Overall the
r-squared of these models are .06, .15. and .42 so the
support measures are
really the critical predictors of parent involvement
here.
So the question is should I be interpreting the reg coefficients only
from equation 3 or for each
IV as it was first entered into the analysis?
