Study Design:
Creating and psychometric testing of a new QoL Questionnaire about Physiotherapeutic Specific Exercises of Scoliosis (Questionnaire of Physiotherapeutic Specific Exercises of Scoliosis-QPSSE).
Purpose:
The purpose of this study is to create a reliable and valid questionnaire for patients suffering from mild and moderate adolescent idiopathic scoliosis (AIS) who have been treated with Physiotherapeutic Specific Exercises of Scoliosis (PSSE) in order to evaluate their quality of life.
Materials And Methods:
The developed questionnaire was based on a thorough literature review as well as on authors' experience. It consists of 53 questions, of which 37 have a positive meaning, 15 have a negative meaning, and 1 is a multiple choice question; additionally, there are 6 "open" questions. Except for the multiple choice question, all other questions are answered on a Likert scale ranging from 1 to 5 points. Five represents a positive meaning or very positive one, whereas one stands for a negative meaning or none at all. Questions were developed by the authors who subsequently categorized the 53 questions into the following eight domains: physical functioning, self-image, Physiotherapeutic Scoliosis-Specific Exercises (PSSEs), psychosocial functioning, cognitive functioning, compliance, motivation, and pain. A pilot study was conducted so that we could calculate Cronbach's Alpha based on the outcome. Due to the COVID-19 pandemic, the authors worked through the Zoom online platform to structure the questionnaire.
Results:
Pearson's correlation coefficient was used for all correlations evaluated. P values of less than 0.05 were considered to be significant. Internal consistency was evaluated with Cronbach's Alpha. Although there were very few missing values, accounting for 0.78% of the total values of the questionnaire, the expectation maximization likelihood algorithm was used to impute data. IBM® SPSS® Statistics Software v.25 was used for the analysis. Cronbach's Alpha coefficients for the overall score were 0.84.
Conclusions:
This original QPSSE was found to be a reliable and valid tool for AIS treated conservatively with PSSE and for the patients' clinicians.
