Reliability

Internal consistency (Cronbach's alpha): Not applicable

Test-retest Reliability (ICC):

Zaino CA (2004)
Intra-rater reliability: One rater scored the same participants in real time and a second time later, with a video

- Population/Disease: Children and adolescents from a convenience sample; n=24, Age range of the sample: 8-14 years

Test-retest reliability
- Intraclass Correlation Coefficient (ICC): 0.94
- Was a definition of stability applied to identify stable patients: No
- Time frame or interval between the two administrations: 2 hours
- Population/Disease: Children and adolescents from a convenience sample; n=25, Age range of the sample: 8-14 years

Inter-rater/ inter-interviewer reliability (kappa):
