Measuring Recovery Using the Individual Recovery Outcomes Counter: A Cross-Sectional Multi-Center Study on Structural Validity in Dutch Mental Health Care.
Margot Metz, Gabriëlle van Son, Floor Stuit and 3 others
PMID 40707403WHAT IT FOUND
The I.ROC total score can give a useful overall picture of recovery in Dutch mental health clients, but subscale scores are not consistently dependable.
Use the 12 items and total score; be cautious with subscales.
Key findings
01The total score across the 12 items had good internal consistency (α = 0.88).
02The best models almost reached the good-fit threshold (CFI = 0.95), but differences from other models were marginal.
03The Vitality and activity factor had insufficient internal consistency (α = 0.67).

What it does not show
The study was cross-sectional, so it did not test whether the factor structure stays stable over time. Severe mental illness and non-severe mental illness were classified by treatment setting rather than individual patient data, so some group labels may be imprecise. Some participants could not be classified into the severe or non-severe group, so the subgroup results do not cover all clients. The Vitality and activity factor had α = 0.67, below the acceptable range, so that subscale score may not be dependable. Several models fit similarly well, so the study did not identify one definitive factor structure. The data were routine first measurements, and some clients may have had previous treatment, so the findings reflect usual registration data rather than a controlled assessment.

The easy way to misread this
Do not conclude that the I.ROC has proven, interchangeable subscales. The study found no single clearly best factor structure, and one subscale was not dependable enough, so check reliability in your own data before using subscales.
