The purpose of this study was to develop a valid and reliable instrume
nt to measure four areas of autonomy. The instrument is composed of fo
ur subscales that measure the following constructs of autonomy: (a) fa
mily loyalty autonomy, (b) value autonomy, (c) emotional autonomy, and
(d) behavioral autonomy. A detailed four-step procedure was used to p
rovide the scale with construct, content, and predictive validity. Pre
sented here is the four-stage process used to develop the Autonomy Sca
le, data supporting the validity and reliability of the scale, and the
final version of the instrument.
