Introduction Background

There are a number of health questionnaires Stress Response Inventory (SRI) Geriatric Depression Scale (GDS) Etc.

Health questionnaires are usually used in clinical trials Collect information from large number of people

04/19/23 3Information and Communications University

Introduction – cont’d Background

Furthermore, health questionnaires can be used as a self-diagnosis tool SRI-stress, GDS-depression

Health questionnaires can provide not only index for diseases but also various information on health status SRI – stress-related symptom information, type of

stress

04/19/23 4Information and Communications University

Introduction – cont’d Background

Health questionnaires can compensate conventional u-healthcare applications Health questionnaires can collect information

which cannot be got from bio-sensors

04/19/23 Information and Communications University 5

Introduction – cont’d Motivation

Access to health questionnaires is limited Only through Web pages and hardcopies

Health questionnaires are not utilized widely in u-healthcare systems

04/19/23 6Information and Communications University

Introduction – cont’d My approach

Port health questionnaires in mobile devices Many people would easily access to health

questionnaires anytime and anywhere

Use standard technologies For easing interoperation with other u-health

applications

Related Work There are few studies on questionnaire

system

K. Morton et al. Developed a general-purpose questionnaire

system Questionnaires are utilized for collecting

information from large number of people

04/19/23 8Information and Communications University

Related Work – cont’d J. Cheng et al.

Developed a general-purpose questionnaire system

Suggest to provide questionnaires ubiquitously

Focus on collecting information from large number of people with questionnaires

MHQS Framework MHQS Framework

Mobile Healthcare Questionnaire Service (MHQS)

Supports development and execution of MHQS

04/19/23 11Information and Communications University

MHQS Framework – cont’d Requirements

Extensibility Large number of health questionnaires and

analysis methods exist Adding new health questionnaires and analysis

methods must be easy

Flexibility Composing various analysis methods must be

easy

MHQS Framework – cont’d Requirements

Reusability Some health questionnaires and analysis methods

can be used in various applications Reusing health questionnaires and analysis

methods must be possible

Interoperability MHQS Framework must interoperate with other u-

healthcare systems

MHQS Framework

MHQS Framework – cont’d Questionnaire content management

Stores questionnaire contents Retrieves queried questionnaire contents Modifies questionnaire contents

04/19/23 16Information and Communications University

MHQS Framework – cont’d Questionnaire response analysis

Analyzes users’ responses and extracts useful information

Ex) SRI SRI diagnose stress by collecting related symptom

information

-> Diagnosis result, related symptom information Each item is assigned to a stress type

-> The type of stress

MHQS Framework – cont’d Questionnaire history management

Stores, retrieves users’ history Enables long-term healthcare services

Questionnaire history analysis Analyzes users’ history and extracts

information on changes of health status Enables long-term healthcare services

04/19/23 18Information and Communications University

MHQS Framework – cont’d Simple Questionnaire Message (SQM)

Is a XML-based message format Carries questionnaire contents and responses Enables pipelining among components

Flexible composition of components
