Abstract

OBJECTIVES

This paper describes the magnitude of effects for family planning programs evaluated with true experimental designs.

METHODS

Studies that used true experimental designs to evaluate family planning programs were identified and their results subjected to meta-analysis.

RESULTS

For the 14 studies with the information needed to calculate effect size, the Pearson r between program and effect variables ranged from -.08 to .09 and averaged .08.

CONCLUSIONS

The programs evaluated in the studies considered have had, on average, smaller effects than many would assume and desire.

摘要

目标

本文描述了采用真实实验设计评估的计划生育项目的效果大小。

方法

识别出使用真实实验设计评估计划生育项目的研究,并对其结果进行荟萃分析。

结果

对于14项具备计算效应量所需信息的研究,项目变量与效应变量之间的皮尔逊相关系数r在-.08至.09之间,平均为.08。

结论

在所考虑的研究中评估的项目,平均而言,其效果比许多人设想和期望的要小。
