Learning objectives
The course is aimed at providing students with knowledge about:
- medical ethics, in order to develop critical thinking and discussion skills on moral, legal and ethical issues related to health professions;
- theories and statistical-psychometric methods for the assessment of behaviors, perceptions, and attitudes;
- the use of computer and technological tools to support the work of rehabilitation professionals and the quality of life of persons with disability;
- research planning and implementation in the rehabilitation domain, taking into account its methodological peculiarities (variable definition, experimental design, statistics) and specific bioethical implications;
- general pathology in order to understand and describe inflammation and cancer as the two main causes of human diseases:
- techniques for the molecular investigation of the above described pathologies;
- programs and models for addressing cancer diseases
Expected learning outcomes
At the end of the course, the student will be able to:
- use computer, epidemiological and statistical methods and tools, as well as apply them to the organization of rehabilitation services, by assessing their appropriateness, effectiveness and efficiency
- plan and conduct research in the rehabilitation field, taking into account its methodological peculiarities (variable definition, experimental design, statistics) and specific bioethical implications

Psychometrics
Course syllabus
- Cumulative questionnaires: typical structures.
Visual analogues and mono-item questionnaires (numeric rating Scales); Multi-item scales like likert and Scales rating; Examples taken from current clinical and experimental practice; Different methods of administration.
- Main epistemological problems:
Latent and fully observable variables; "reflective" and"training"; Causal or co-variation relationship between latent variables and observed behaviours; Difference between evaluation (multidimensional decision-making) and true measure (one-dimensional process)
- Ideal properties of the measure: Unidimensionality; Discrimination (linearity, precision, targeting-accuracy, floor-to-ceiling effect); Estimation of missing scores; Not redundancy (cancellation of "Jackpot"); Invariance across sub-groups (including intra-inter-observer repeated measures); Possibility of correction according to the severity of the examiner
- The concept of the"validity"of the measure.
- Scores and measurements. Distortions induced by raw scores (raw scores).
- From counting to true measurements: from traditional test theory to modern item response theory: Observed scores (Observed-raw scores) and scores expected from the theoretical model (expected scores); difference between expected
and Observed scores: "residual" and data-model fit; maximum likelihood estimation: maximum does not mean great; Georg Rasch's original dichotomic model: prescriptive, non-descriptive Rasch-derivative models: scale rating (Andrich model), partial-credit (Masters model) and many-facets
- Solutions offered by Rasch models: Linearity; Single response error estimates; internal coherence estimates in response profiles; LAPMER scale; missing values estimates; data-model fit; stability of item challenge hierarchy among subgroups; differential item functioning and differential test functioning correction through item-split
In particular: solution to the problem of translation across different linguistic contexts (metric vs linguistic equivalence). McGill Pain Disability Questionnaire and BACKILL scale; Multiple examiners mis-fit: FISM-ProQual™ for research projects evaluation
- Examples of frequently used scales with limited validity
- Example of scale construction (ABILHAND) based on Rasch criteria
- Video Examples of manual performances; comparison between visual evaluation of abilities and measurement through ABILHAND
- Use of nomograms to graphically convert scores of linear measures; missing values; software freeware MINISTEP™.
- Evaluation profiles through scales; example with upper limb functioning
- Behavioral measures based on instrumental measures of performance (e.g.strength; balance): advantages and limits vs questionnaires. Subjectivity and objectivity in psychometric or behavioral measures
Basic statistics:
- Measurement scales and their features
- Central tendency and dispersion measure.
- Statistical hypothesis / Statistical hypothesis testing
- Test of association among variables: Independence test, correlation indices.
- Graphing variable relationships (level of association; shared variance)

Validity:
- Construct validity
- Validity associated with construct operationalization
- Face validity
- Content validity
- Structural Validity
- Exploratory Factor Analysis / Principal Component Analisis
- Common / Unique / Latent factors
- Correlation matrix
- Explained variance (Factors / Components)
- Factor solutions
- Varimax / Oblimin rotations
- Number of factors to be retained: employed criteria
- Graphing variable relationships in the context of Factor Analysis
- Confirmatory Factor Analysis
- Latent factors
- Fit indices (absolute, comparative, parsimonious)
- Criterion validity
- Predictive validity
- Cuncurrent validity
- Congruent validity
- Convergent / divergent / discriminant / differential validity

Reliability:
- Measurement error (systematic / random)
- Measurement precision / stability
- Split-half reliability
- Cronbach alpha
- Test-retest reliability
