This study examined the measurement quality of an abbreviated version of the Caregiver Strain Questionnaire. The CGSQ-Short Form 7 (CGSQ-SF7) is practical for routine assessment of objective and subjective internalized caregiver strain. The subjective externalized subscale is not included in the CGSQ-SF7. Findings indicate that the reliability and validity of the shortened objective and subjective internalized subscales are comparable to the original. Examination of construct validity suggested that caregiver, youth, and clinician ratings of child clinical severity were related to objective caregiver strain. However, youth and clinician ratings of child clinical severity were not related to subjective internalized caregiver strain.
