A female sample (N = 349) was administered the Attitude Interest Schedule (AIS) and the Cesarec-Marke Personality Schedule (CMPS) at the ages of 15 and 25. It was found that during adolescence subjects change towards a more conservative feminine self-image. Differential stability, based on the AIS scores, was substantial. Masculinity-femininity appeared to be related to needs as measured by the CMPS. Masculinity was related positively to instrumental needs and negatively to expressive needs.
