Hello Araceli, I am not entirely sure, but in my opinion self-determination may be related to self-efficacy and I am sure such measures exist. 

Hope it helps a bit.

Dear Aracelli,

On the one hand, I can suggest to contact to Prof. Michael Wehmeyer

https://www.researchgate.net/profile/Michael_Wehmeyer

He has a lot of experice on Self Determination and all his publications could be of interest for you.

On the other hand, if you are looking for an assesment tool in Spanish, probably the best option could be this:

You could find more information in the contributions of Prof. Miguel Ángel Verdugo

Graciasss

Sí, Wehmeyer y todo el trabajo del INICO lo conozco... Pero no me refiero a la autodeterminación de la persona  , sino a la perspectiva de las familias (no solo como "informantes", sino cómo viven ellas la autodeterminación, si comprenden qué significa, relación con sus propios valores familiares, matices culturales...). Hay investigación cualitativa al respecto, pero no dan mucha información sobre método..

En ello estoy.. Es lo que investigo (trato de investigar) y era por si alguien conocía algún instrumento en ese sentido, o trabaja en ello. 

gracias de nuevo :-)

OK

Hello Araceli

I am undertaking research (as a PhD student) on self-determination of adults with intellectual disability within the context of family relationships. As part of this I am trying to understand the family's experience of supporting the development of self-determination in their family member, the role they play, any changes in their relationships and how these are negotiated. I will be doing this as a qualitative study using an Interpretative Phenomenological Analysis (IPA). So your topic is of interest to me.

In regards to your question, there are instruments for assessing self-determination, not sure if they relate to family perceptions, however might be worth looking at - ARC Self-Determination Scale (1995) is one, another is the AIR Self-Determination Scale (American Institutes for Research, 1994). Another that might be of interest to you is the Choice Questionnaire (Stancliffe and Parmenter, 1999).
