Deficiencies in research baseLittle work on attitudes and experiences of usersLittle information science perspectiveResearch has focused on feasibility, outcome, pilot studies

PurposeUnderstand perceptionsUnderstand health consumer acceptance

Significance

• Understanding perceptions– Helps usability– Faciltiates design– Helps justify development– Facilitate health education– May help develop evaluationmetrics of

devices

Research question• CENTRAL QUESTION• How do individual perceptions of mobile phone eHealth contribute to the acceptance

of this technology?• ASSOCIATED SUBQUESTIONS REGARDING PERCEPTIONS• What perceptions are associated with mobile phone eHealth?• What perceptions are related to the technical characteristics of mobile phone

eHealth?• What perceptions are related to health behavior change? • What perceptions are related to health information behavior?• There is an emphasis on health behavior change and health information behavior

because of the lack in their examination and of my interest in information science. • ASSOCIATED SUBQUESTIONS EXPLORING THE PROCESS OF ACCEPTANCE• How do individuals describe their acceptance (or rejection) of mobile phone eHealth?• How do individuals explain the contribution of their perceptions towards their

acceptance (or rejection) of mobile phone eHealth?• What types of perceptions contribute to the acceptance of mobile phone eHealth? • What types of perceptions contribute to the rejection of mobile phone eHealth?

It helps to have a framework

• Looked at other dissertations

• Looked for templates that work for me

Theory

• Helped me shape my research questions• Analytics Generalizations helped me to work

from• Theory: The common theme among the theories

is that individual, subjective perceptions of innovations shape acceptance and adoption behavior. – Respectively, they include the Theory of Planned

Behavior, Diffusion of Innovations theory, the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology.

Writing

• Parkinson’s law

• Precondition to good writing is writing when you don’t feel like it …

• “thinking on paper”

Methodology• Qualitative versus quanitative• Quantitative defined• Qualitative defined• Relevance to health research

– Comprehending health beyond the clinical and objectively measured elements – advancing a holistic u derstanding of health

– Complement quantiative research by proposing hypotheses for testing– Incrasingly peopular I health services andpolicy research– Anecdotes fit into how health prfoessionals learn

• Relevance tomoble phone eHealth research– Exploratory– Holistic view is helpful to understanding new emerging technologies

especially people’s responces to it

Question my biases

• Understanding the question, it led to a methodology

Case study

• Define case– A case study is "an empirical inquiry that:– investigates a contemporary phenomenon within its real-life

context, especially when – the boundaries between phenomenon and context are not

clearly evident" (Yin, 2003) – Creswell defines the "case" in case studies as the "bounded

system or the object of study” (2007).  It may be an event, a process, a program, or several people" (Creswell, 2007). 

• Boundaries and parameters– Subjective and individual perceptions of mobile phone eHealth

can be studied in order to understand the acceptance of this innovation.

– Different groups of health consumers based on criteria

Acknowledging researchers role

• Biases medical librarian, positive bias, but this can be used to my advantage

• Ethics IRB

• Internationl internaitonl perspective

Fostering research quality• Four markers of quality in empirical social research include (Yin, 2003):• Construct validity: Are operational measures correctly used for studying the key concepts?• Internal validity: In studies that explain or identify causality, it is important to identify causal

relationship between conditions that are clearly distinguished from spurious relationships.• External validity: Examining the domains to which the findings may be generalized• Reliability: Can the study procedures be repeated with the same results?• Table 7 summarizes the tactics for research quality in this study.• Table 7 Case study tactics for research quality (adapted from the work of the COSMOS

Corporation as interpreted by Yin (2003))• <see table 7> TestsCase study tacticPhase of research in which tactic occursConstruct

validityUse of multiple sources of evidenceEstablish chain of evidenceHave key informants review draft case study reportData collection and compositionInternal validityDo pattern-matchingDo explanation-buildingAddress rival explanationsData analysisExternal validityUse replication logic in multiple-case studiesResearch designReliabilityUse case study protocolDevelop case study databaseData collection

• The tactics for construct validity and reliability are explained in section 12.• The tactics for internal validity are explained in section 19.1.• External validity is cultivated via replication logic.

Data to be collected

• Documentation– Qualitative research studies– Poupular media

• Interviews• Physical artifacts• Principles for data collection

– Multiple sources of evidence– Case study database– Maintaining a chain of evidence
