Development of a Bangla version of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Bath Ankylosing Spondylitis Functional Index (BASFI).

Development of a Bangla version of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Bath Ankylosing Spondylitis Functional Index (BASFI). This biphasic observational study performed the translation and adaptation of the questionnaires carried out in 5 steps with pre-testing in 30 AS patients followed by the psychometric validation of the pre-final Bangla version utilizing content and construct validity in 115 AS patients. The reliability was examined through internal consistency and test-retest reliability involving 23 AS patients. After pre-testing of the pre-final Bangla version of both indices, the psychometric validation found that the convergent validity of Bangla version of BASDAI showed strong correlation with C-reactive protein (r = .75) and the Maastricht Ankylosing Spondylitis Enthesitis (r = .64), and moderate correlation with erythrocyte sedimentation rate (r = .49). Again, the Bangla BASFI showed significant correlation with occiput-to-wall distance (OWD) (r = .50), mentum-to-sternum distance (MSD) (r = .50), chest expansion (CE) (r = -.40), finger-to-floor (FFD) (r = .55), number of swollen joints (r = .69), and number of enthesitis (r = .68). The divergent validity demonstrated weak correlations between BASDAI and OWD (r = .43), MSD (r = .34), CE (r = -.44), FFD (r = .47). The divergent validity of BASFI could not be assessed due to lack of a suitable comparing parameter. The instruments revealed acceptable internal consistency as Cronbach's alpha was 0.86 for BASDAI and 0.93 for BASFI. A 7-day test-retest reliability measured by the intraclass correlation coefficient were 0.80 (CI at 95% = 0.58-0.90) for BASDAI and 0.83 (CI at 95% = 95% 0.64-0.92) for BASFI respectively. Bangla version of BASDAI and BASFI may be useful in disease activity and functional ability assessment in AS patients.

Validity of a Venezuelan version of the Bath Ankylosing Spondylitis Functional Index and Bath Ankylosing Spondylitis Disease Activity Index.

Spondyloarthropathies (SpA) are disabling diseases with a prevalence of 1.9% in the general population. The indices designed for monitoring the disease should be valid, reliable and cross-culturally adapted for decision-making concerning the appropriate treatment. Changing an adjective or pronoun in a self-administered questionnaire could be the big difference in condensing an idea in a few words and transmitting that concept to all those who share the same language. To develop a Venezuelan version of the original English version of the BASDAI/BASFI and to evaluate its reliability and validity in Venezuelan patients with SpA. Certified linguists were needed for the translation of a Venezuelan version of the BASDAI/BASFI. The evaluation of reliability and validity was performed by calculating correlation coefficients in addition to Cronbach's alpha correlation between the BASDAI score and the clinical parameters (for example: erythrocyte sedimentation rate, C-reactive protein, modified Schöber test, occiput-to-wall distance and enthesis count). We studied 40 patients including 31 men (77.5%) and 9 women (22.5%). The mean age was 35.9 years ± standard deviation (SD) 12.01 and the disease duration was 11.5 years (± SD 9.5). The most common diagnoses were undifferentiated spondyloarthritis (45%), ankylosing spondylitis (27.5%) and psoriatic arthritis (20%). The incidences of reactive arthritis, ankylosing spondylitis and juvenile Reiter's syndrome were 2.5% each. The test-retest reliability of the BASDAI and BASFI was high (R = 0.99 and 0.99, respectively; P<.0001). The internal consistency for the BASDAI was high (Cronbach's alpha = 0.88; P=.002) and the intraclass correlation coefficient for internal consistency: 0.9867 (P=.001). Internal consistency for the BASFI: Cronbach's alpha = 0.7985 (P=.002), intraclass correlation coefficient for internal consistency: 0.9055 (P=.001). Construct validity of the BASDAI was high for general well-being of the patient (R = 0.84) and for enthesis count (R = 0.84). Low back pain showed moderate correlation with BASDAI (R = 0.69; P<.0001) and the erythrocyte sedimentation rate showed a low correlation (R = 0.39683; P=.0112). The Venezuelan version of the BASDAI/BASFI could be used in clinical research to assess and evaluate the course of disease activity in Venezuelan SpA patients.
