Motivations to Use Birth Control – Add Health

The questions on this tool are taken from a larger questionnaire administered to students and young adults ages 15 and up as part of the National Longitudinal Survey of Adolescent Health (Add Health). The Add Health study is a nationally representative study originally designed to examine how social contexts (such as families, friends, peers, schools, neighborhoods, and communities) influence teens' health and risk behaviors. The study is now examining how health changes over the course of early adulthood. The study began in 1994 under a grant from the NICHD, with co-funding from 17 other federal agencies.  The Add Health study is the largest, most comprehensive survey of adolescents ever undertaken.

Scoring / Benchmarking
Scoring:

Before analyzing data, code answer options as follows:
1 = Strongly agree
2 = Agree
3 = Neither agree nor disagree
4 = Disagree
5 = Strongly disagree

Question # 6 should be reverse scored.

Individual-level scores can be created by dividing the sum of all the responses by the total number of questions answered, to obtain an average score.

Aggregate-level summary scores can be created, for example, by recoding participants with an average score of 3 or less as a 0 and 4 or higher as a 1. Then look at the percentage coded as 1 and track changes in that percentage over time.

Benchmarks:
No benchmarks have been developed for this measure.
