a

We show the bases for hypotheses in 3 categories: (1) an earlier effect on the same specific measure or construct in an earlier phase of the trial, (2) an effect on the same measure or construct in other trials, and (3) effects in earlier phases or trials that predict the current outcomes on theoretical or epidemiological grounds. When the prediction was made from the same measure, the basis for the hypothesis is shown on the same row; otherwise, it is shown on the construct row. Note that those outcomes hypothesized to be greater for particular subgroups are shown in the last column.

b

Outcome domain. Specific variables assessed are shown under each outcome domain. Outcomes were selected on the basis of their being affected in earlier phases of this trial or the preceding trial or on theoretical and epidemiological grounds, with attention paid to those aspects of functioning that are of clinical or public health importance and that could be assessed without overburdening respondents.

c

Subgroup defined by youths' mothers at registration11 falling into the lower half of the distribution of an index composed of the average z scores of women’s intellectual functioning,21 mental health,22 and sense of mastery23 plus self-efficacy (based on mothers’ confidence in their ability to accomplish key NFP behavioral objectives).24

d

The intervention effect on nonverbal intelligence at age 6 was a trend overall and for the LPR group, derived from the Kaufman Assessment Battery for Children Mental Processing Composite.29 The analysis of the whole-scale Kaufman Assessment Battery for Children Mental Processing Composite was significantly different for the treatment-control contrast, both overall and for the LPR group at age 6.13 The nonverbal subscale trend was not reported in the earlier publication.13 The Kaufman Brief Intelligence Test 2 administered at age 18 is a shortened version of intellectual functioning based on the full-scale Kaufman Assessment Battery for Children.

e

Exploratory outcome. Graduating with honors was not part of the original measurement design per se. The original plan called for gathering school records of grade point averages and disciplinary records, which were incomplete, leading us to eliminate them as part of the final measurement design. We discovered, however, that states sent information on graduation with honors, which aligns with the original measurement design and thus is included in this report. Note that all states to where participants moved record graduating with honors, with the exception of Mississippi. Seventeen participants graduated from Mississippi schools (10 control; 7 NV); they are included in the analysis as not having graduated with honors.

f

Exploratory outcome. SSI (disability) was based on parent and/or caregiver report and not included in the original measurement design. The question is relevant to this report and thus is included here.
