Study Description
Brief Summary
The aim of this study is to describe the development of the Work In Progress questionnaire, a tool designed to evaluate commitment in persons, and its psychometric validation process in the context of low back pain.

Detailed Description
The study design is cross-sectional.
The following methodology will be applied as for the development of the Work In Progress questionnaire (WIP), a tool designed to evaluate commitment in persons, and its psychometric validation:
-
item generation and selection: the first defines the content of an index and ensures the most important topics are well-thought-out. The second eliminates redundant items, and decreases the number to a total that is feasible to administer while ensuring the scale measures the construct of interest.
-
psychometric analysis: reliability (internal consistency by Cronbach's alpha, test-retest reliability by Intraclass Correlation Coefficient 2.1), Measurement error (calculated by multiplying the standard error of measurement (SEM) by the z-score associated with the desired level of confidence (95%, in our case) and the square root of 2), and construct validity by hypothesis testing the correlations (Pearson r) with related measures (Pain Catastrophizing Scale, Oswestry Disability Scale, Numerical pain Rating Scale).

Outcome Measures
Primary Outcome Measures
- WIP questionnaire [At the moment of the questionnaire administration]
Work In Progress questionnaire; score varying from 0 to 30, with higher scores indicating greater commitment
- WIP questionnaire [After 7-10 days later the first assessment (please, see above) as concerns test-retest assessment reliability.]
Work In Progress questionnaire; score varying from 0 to 30, with higher scores indicating greater commitment
Secondary Outcome Measures
- PCS [At the moment of the questionnaire administration]
Pain Catastrophizing Scale; score varying from 0 to 52, with higher scores indicating greater catastrophizing
- ODI [At the moment of the questionnaire administration]
Oswestry Disability Index; score varying from 0 to 50, with higher scores indicating greater disability
- pain NRS [At the moment of the questionnaire administration]
Numerical pain Rating Scale; score varying from 0 to 10, with higher scores indicating greater pain intensity
