Cultural Adaptation Clinical Trial
Official title:
Turkish Version of MedRisk Instrument for Measuring Patient Satisfaction With Physical Therapy Care: Its Cultural Adaptation, Validation and Reliability Study
The aims of this study were to perform cultural adaptation of the MedRisk Instrument for Measuring Patient Satisfaction With Physical Therapy Care (MRPS) instrument and provide information regarding the factor structure, group-level reliability, and criterion-referenced validity of the instrument in Turkish speaking patients.
Patient satisfaction with physical therapy has become an important concern in health care,
used to monitor patient perceptions of the quality of physical therapy care services.
Measurement of patient satisfaction may provide useful information which may improve the
quality of health care. The "MedRisk Instrument for Measuring Patient Satisfaction With
Physical Therapy Care" (MRPS) is one of these instruments, which has undergone reliability
and validation testing.The MRPS is a 20-item (18 items and 2 global measures) questionnaire
which assess patient experience about therapist, registration process and convenience of
environment.
A survey on a consecutive sample of patients from various regions in Turkey who were
receiving outpatient physiotherapy programs was recruited.The study was divided into two
phases: Phase I, the cross-cultural adaptation, which involves the translation procedures
into Turkish and preliminary probe in the target population; and phase II, which involves
the reliability and validation study.
After providing informed consent, for test-retest reliability, all subjects were asked to
complete the MRPS twice; the first at least after receiving three sessions of physiotherapy
and the second four days later which could coincide with the date of their discharge but not
later. Subjects provided information regarding their age, sex, and location of primary
symptoms prior to completing the instrument.Factor structure.
The construct validity was evaluated by factor analysis method. An exploratory factor
analysis, using principal components analysis with varimax rotation was performed.Criterion
validity was addressed by determining the correlation between two global measures of
satisfaction and each of the 18 items. The measurement properties of the potential factors
were investigated by determining correlations of the factors to the global measures and
10-cm Visual Analog Scale (VAS) which evaluates the level of patient satisfaction with
higher scores indicating better satisfaction. Pearson correlation coefficient was used to
assess the strength of the linear relationships. Test-retest reliability was examined by
calculating the Intraclass Correlation Coefficient (ICC). Internal consistency relates to
homogeneity of an instrument, which is assessed with Cronbach's alpha
