Abstract

This chapter uses the recently conducted evaluation of Building Strong Families as an example to explore two challenges for family research: (1) managing multiple comparisons when evaluating a program that aims to influence a wide range of outcomes and (2) dealing with potential bias introduced by examining truncated measures (i.e. measures that are not defined for all sample members). The evaluation’s strategy for dealing with multiple comparisons was to limit the number of outcomes that provide the key test of program effectiveness, and then use methods such as outcome domain composite indices and statistical adjustments for multiple comparisons to assess the strength of the pattern of impact findings. The evaluation’s strategy for dealing with truncated variables was to assess the risk of truncation bias using existing standards for sample attrition in experimental evaluations, and then use that assessment to determine which analysis may be included in evaluating program effectiveness.

Notes

  1. 1.

    The members of the couple had to be able to speak one of the languages in which BSF was offered in their location. All locations offered BSF in English, and some also offered BSF in Spanish. At intake, couples were screened for intimate partner violence. If there was evidence of intimate partner violence that could be aggravated by participating in BSF, the couple was not considered eligible for BSF and was referred to other services.
