For a brief yet comprehensive triage, three high impact psychosocial items should be added as independent contributors.
All scores were designed so that 0, the lowest possible value, designates the case of parents not at all impacted, and 100, the highest possible value, corresponds to the case of parents reporting the highest impact category for all items of the dimension.
The mini-OQLQ has ten items, constructed from the two items with the highest impact in each of the five domains on the original OQLQ.
Our observations suggest that the highest impacts concern some items from the domains representing 'physical pain'; 'functional limitation' and 'psychological discomfort' in this young adolescent population.
In our study, items which reflect the highest impact on HRQoL are placed at the top of the continuum and those which reflect the lowest impact are placed at the bottom.
Three separate IRT models were created for NMEs, reflecting the experience, bothersome, and impact items to define a higher-order NMEs variable used in SEM.
The mini-OQLQ includes the two items from the OQLQ with the highest impact in each of the five domains (symptoms, physical functioning, emotional functioning, activities of daily living, and leisure), for a total of 10 items (Additional File).
Preliminary analysis indicated high levels of concordance in responses to the PIPP Impact items (associated with function and experience) and PIPP Distress items (associated with feelings), despite linguistic differentiation.
The item impact method used data from the CPQ11 14 item reduction study to select the questions with the highest impact scores in each domain.
Each item of the BBQ was scored 0 (lowest) to 6 (highest impact).
