On the customer side, Gallup does phone interviews for us, asking two types of questions, functional and emotional.
Explanation is provided by lower-level mechanisms; their explanatory role is to replace final why-necessarily questions (functional) with proximate how-possibly questions (molecular).
Questions are divided into three domains: symptoms (4 questions), functional status (4 questions), and mental state (2 questions).
Items are grouped into four domains: oral symptoms (6 questions), functional limitations (9 questions), emotional well-being (9 questions), and social well-being (12 questions).
The short version of the CPQ11 14 – ISF 16 comprises 16 questions that can be classified into four domains: oral symptoms (4 questions), functional limitation (4 questions), emotional well-being (4 questions) and social well-being (4 questions).
It is structurally composed of 37 items distributed among 4 domains: oral symptoms (6 questions), functional limitation (10 questions), emotional well-being (9 questions) and social well-being (12 questions).
The Danish CPQ11 14 contains a total of 39 questions: 2 global questions about dental health, 6 questions on oral symptoms, 9 questions on functional limitations, 9 questions on emotional well-being and 13 questions on social well-being.
The Danish CPQ8 10 contains a total of 27 items: 2 global questions about dental health, 5 questions on oral symptoms, 5 questions on functional limitations, 5 questions on emotional well-being and 10 questions on social well-being.
This has 24 questions that are each evaluated on a 5-point severity scale (0, none to 4, extreme), it assesses three areas: pain (5 questions), stiffness (2 questions) and functional impairment (17 questions).
Thus the stability question of functional equations is that how do the solutions of the inequality differ from those of the given functional equation?
