Teen pregnancy prevention has been a major component of the school sex education curriculum for the past two decades, as well as the focus of many community agency programs. A difficulty in evaluating these programs is the lack of instruments in measuring teens' attitudes and intentions regarding teenage pregnancy. The sixteen-item Teen Attitude Pregnancy Scale (TAPS) was developed for this purpose. It is based on a model of (a) Future Orientation, (b) Realism About Child Rearing, (c) Personal Intentions, and (d) Sexual Self-efficacy. Overall, the TAPS demonstrated good internal consistency and concurrent validity for the samples considered here. Additionally, exploratory factor analysis revealed evidence of validity for this four-factor model of teens' attitudes toward pregnancy. © 2002 Wiley Periodicals, Inc.
