strengths

• • Reliability: Bem (1974) re-administered the Bem sex-role inventory to a sample of participants 4 weeks after they originally completed the test. She found the participants’ answers were consistent both times, suggesting the Bem sex-role inventory has good test-retest reliability.
• predictive power- some studies- Lubinski et al (1981) supports Bem's prediction that androgyny is psychologically advantageous
