Two items were therefore deleted to produce a six-item scale with excellent reliability (see Table 2).
The aims of this Patient Reported Outcome Measurement Information System (PROMIS) study were to (1) conceptualize children's subjective well-being (SWB) and (2) produce item pools with excellent content validity for calibration and use in computerized adaptive testings (CATs).
Regarding the first and primary goal, our 104-item survey distilled down well into 16 multi-item constructs (all with excellent reliabilities) in this large sample of university students from varied disciplines.
With the portable ultrasound device it was possible to adequately evaluate the different items with good to excellent agreement.
Depressive symptoms will be measured with the Quick Inventory for Depressive Symptoms (QIDS-SR), a 16-item self report scale with excellent psychometric proportions [ 11].
An iterative procedure reduced the summary scale to 8 items, producing a unidimensional scale with excellent fit to the Rasch model (Table 3, Analysis 6).
Seventeen HFS-W items showed excellent fit, with ranges of infit values (0.77 1.25) and outfit values (0.72 1.27).
These items together successfully operationalized functional ability in DMD, with excellent targeting and reliability (Person Separation Index: 0.95; Cronbach's α: 0.93), stable item locations, and good fit to the Rasch model (mean person/item fit residual: −0.21/−0.44, SD: 0.32/1.28).
The menu is not so much unusual as subtly different, with items like an excellent appetizer of a cake of bacalao, or dried salt cod, that is puréed and deep-fried until crisp around the edges and airy within, paired with a slender pepper stuffed with bacalao ($8).
The incident items contribute to a patient-reported incident index, with excellent data quality and hospital-level reliability.
