Lower scores indicate dissatisfaction and higher scores indicate satisfaction. The LiSat-9 takes 10-30 minutes to complete, requires no formal training, and is free to use. The LiSat-9 has demonstrated adequate to excellent internal consistency,3. 4. excellent reliability,5 adequate to excellent concurrent validity,4 and adequate to excellent convergent validity2 across several studies. The LiSat-9 also demonstrates responsiveness, varying from small to large effect size, 1 year after discharge from inpatient rehabilitation.6 In addition, there is an 11-item version available that includes domains of somatic and psychological health.
