Studies have shown that the caregiver and youth versions of the JIFF have good correspondence rates. JIFF scores at entry into a program have been found to predict recidivism. In addition, excellent internal consistency of the scale and subscales has also been found.
After the interview, staff can immediately view the findings and print the JIFF Summary Report. Key results, such as risk behaviors and mental health concerns, are instantaneously displayed as well as a chart showing extent of youth's needs across the 10 domains. The youth’s progress is tracked over time when the JIFF is re-administered.
