Last Updated

June 05, 2015

Purpose

The Child Occupational Self Assessment (COSA) is a self-report of occupational competence and value for everyday activities influenced by components of the Model of Human Occupation (MOHO). The COSA measures how competently children feel engaging in and completing activities and the values associated with these activities (Kramer, Kielhofner, & Smith 2010).

The COSA can be administered in 1 of 3 ways, depending on each child’s abilities:
1) Youth rating form with pictures
2) Youth rating form without pictures
3) Card sort
Children are reminded to that there is no right or wrong answer and to pick the best choice for how they feel.
There is no “score” for the COSA. Therapists may use MOHO theory to interpret the COSA and select the most appropriate way to share this interpretation with others (Kramer et al., 2014).

Considerations

The following factors should be considered:

Age
Appropriateness of item context
Appropriateness of rating scale structure given youth’s abilities
Youth’s capacity to identify interest and reflect on performance.
Youth must be able to identify interests and reflect on performance; consider acuity level
Therapist should consider if content of items is appropriate for therapy context (e.g. most items cover everyday activities of a school-aged youth). Items may not facilitate addressing specific fine motor or vocational skills (Kramer et al., 2014); consider level of care and setting
Some translation inaccuracies were identified in the Dutch version of the COSA
