ÖZET
Amaç: Subjektif Fiziksel ve Sosyal Sonuç İndeksi [Subjective Index
of Physical and Social Outcome (SIPSO)], inme hastalarında topluma adaptasyon
düzeyini ölçmek için geçerli ve güvenilir bir araç olarak rapor edilmiştir.
Bu çalışma, SIPSO’nun Türkçeye uyarlanmasını ve modern
psikometrik analiz (Rasch analizi) kullanarak inme geçiren hastalarda güvenilirliğini
ve geçerliliğini test etmeyi amaçlamaktadır. Gereç ve Yöntemler:
Kültürlerarası adaptasyon, güncel önerilere göre yapıldı. İç yapı
geçerliliği Rasch analizi, güvenilirlik iç tutarlılık ve Kişiden Ayrılma İndeksi
[Person Separation Index (PSI)] ile değerlendirildi. Dış yapı geçerliliği,
SIPSO ile Beck Depresyon Ölçeği [Beck Depression Scale (BDS)],
Mini Mental Test, Fonksiyonel Bağımsızlık Ölçeği [Functional Independence
Measure (FIM)], Barthel İndeksi [Barthel Index (BI)], Fonksiyonel
Ambulasyon Ölçeği [Functional Ambulation Scale (FAS)], Rivermead Mobilite
İndeksi [Rivermead Mobility Index (RMI)] ve İnme Etki Ölçeği 3.0
[Stroke Impact Scale 3.0 (SIS 3.0)] arasındaki korelasyonlar analiz edilerek
değerlendirildi. Test tekrar test güvenilirliği, sınıf içi korelasyon katsayısı
ve Rasch analizi ile değerlendirildi. Bulgular: Toplumda yaşayan
toplam 179 inme hastası dâhil edildi. SIPSO fiziksel alt ölçeğinin iç tutarlılığı,
Cronbach’s α 0,92 ve PSI 0,95 ile mükemmel sonuç gösterdi. SIPSO
sosyal alt ölçeğinin iç tutarlılığı, Cronbach’s α ve PSI 0,86 ile mükemmel
sonuç gösterdi. Dış yapı geçerliliği, BDS, FIM, BI, FAS, RMI ve SIS 3.0 ölçekleri
ile yüksek düzeyde korele idi (p<0,001). Sonuç: SIPSO’nun Türkçe
versiyonu inmeli hastalarda aktivite ve katılımı ölçmek için geçerli ve güvenilir
bir ölçektir.
Anahtar Kelimeler: Rasch analizi; inme; sonuç ölçütleri; geçerlilik; güvenilirlik
ABSTRACT
Objective: The Subjective Index of Physical and Social
Outcome (SIPSO) has been reported as a valid and reliable tool for measuring
the level of community integration in stroke survivors. This study
aims to adapt the SIPSO into the Turkish language and to test its reliability
and validity in stroke survivors by using modern psychometric analysis
(Rasch analysis). Material and Methods: The cross-cultural
adaptation was performed according to the current recommendations. Internal
construct validity was assessed by Rasch analysis, reliability by internal
consistency and Person Separation Index (PSI). External construct
validity was evaluated by analyzing correlations between the SIPSO and
the Beck Depression Scale (BDS), Mini Mental Test, Functional Independence
Measure (FIM), Barthel Index (BI), Functional Ambulation
Scale (FAS), Rivermead Mobility Index (RMI), and the Stroke Impact
Scale 3.0 (SIS 3.0). Test-retest reliability was assessed by intraclass correlation
coefficient and Rasch analysis. Results: A total of 179 community-
dwelling stroke survivors were included. Internal consistency of the
SIPSO physical subscale showed good to excellent results with Cronbach’s
α of 0.92 and PSI of 0.95. The internal consistency of the SIPSO
social subscale showed good to excellent with Cronbach’s α and PSI of
0.86. External construct validity was highly correlated with BDS, FIM,
BI, FAS, RMI, and the SIS 3.0 scales (p<0.001). Conclusion: The Turkish
version of the SIPSO is a valid and reliable scale for measuring activities
and participition in patients with stroke.
