Background:
Adolescent idiopathic scoliosis (AIS) is a three dimensional disease
of the spine, with a Cobb angel greater than 10º. AIS affects children in the age
of 12-16, and develops during the growth spurt. Treatment of AIS is correction
of the spine by either brace treatment or surgery. Haher et al created the SRS
22 questionnaire as a tool to monitor health related quality of life in scoliosis
patients, but no previous Danish version has been validated.
Purpose / Aim of Study:
To evaluate the validity and reliability, of the Danish
adapted version of SRS 22.
Materials and Methods:
The SRS 22 were translated and cross cultural adapt-
ed, according to the guidelines from WHO. The SRS22 Danish version was dis-
tributed to 262 patients with scoliosis and 50 age matched controls, together
with SF12. All data where analyzed by a independent statistician.
Findings / Results:
A total of 207 questionnaires (79.2% response rate) were
retrieved.165 questionnaires from scoliosis patients and 42 from healthy con-
trols. No floor effects was noted. In the scoliosis patients, moderate ceiling ef-
fects were observed on the Satisfaction with Management domain. Reliability
of the SRS-22 seemed good with a Cronbach á of 0.93 in scoliosis patients,
0.90 in healthy controls. In patients, good reliability was found for all domains:
Pain, 0.88; Self-image, 0.87; Function, 0.89; Mental Health, 0.90; Satisfaction
with Management, 0.68. The concurrent validity showed good reliability with
an overall á of 0.88. The results were statistically significant at P <0.05. The
discriminant validity was tested with a t-test. All domains differed significantly
and reveal scoliosis patients have lower scores compared with the controls.
Conclusions:
The Danish translated version of SRS 22 is valid, and can detect
difference between patient with scoliosis and a age matched healthy control
group.
