Survivor validation of recovery satisfaction is binary, nothing special! Did you get 100% recovered? Y/N? If that is not your satisfaction scale, you're dong it all wrong!

ABSTRACT
Purpose: This study aimed to evaluate the Turkish validity and reliability of the Pound Satisfaction
Scale (PSS).
Methods: For the adaptation of the PSS to Turkish (PSS-Tr), the translation and back-translation
process was carried out by following the international guidelines. Confirmatory factor analysis (CFA)
was performed to measure structural validity. The relationship between PSS-Tr and the Patient
Satisfaction Scale in Physiotherapy (PSSP) and the SF-36 was assessed for construct validity.
Convergent validity was evaluated computing by the Average Variance Extracted (AVE). Cronbach’s
alpha coefficient and Composite reliability (CR) for internal consistency of the PSS-Tr and Bland-
Altman plot and test-retest reliability analysis for temporal consistency were used.
Results: The study included 130 stroke patients. The fit index values of the CFA showed that
the structural validity of the PSS-Tr was appropriate (χ2/sd=1.779, RMSEA=0.075, GFI=0.911,
AGFI=0.853, CFI=0.955, NFI=0.905). A high correlation was found between the PSS-Tr total
score and the PSSP (p=0.001, r=0.672). A moderate correlation was found between the hospital
satisfaction sub-dimension of PSS-Tr, and the sub-dimensions of SF-36 (p=0.001, r=0.484-0.609),
while a low correlation was found between the home satisfaction sub-dimension of the PSS-Tr and
the physical functioning (p=0.002, r=0.266) and physical role (p=0.035, r=0.180) sub-dimensions of
SF-36. And also the PSS-Tr was found to have good internal (Cronbach alpha= 0.895, CR=0.94) and
temporal consistency (ICC = 0.976).
Conclusion: The Turkish version of the Pound Satisfaction Scale (PSS-Tr) is reliable and valid. The
PSS-Tr may be useful for clinicians and researchers in assessing satisfaction with rehabilitation in
stroke patients.
