Constructing Grounded Theory: A Practical Guide through Qualitative Analysis

Background: Internet sources are becoming increasingly important in seeking health information, such that they may have a significant effect on health care decisions and outcomes. Hence, given the wide range of different sources of Web-based health information (WHI) from different organizations and individuals, it is important to understand how information seekers evaluate and select the sources that they use, and more specifically, how they assess their credibility and trustworthiness. Objective: The aim of this study was to review empirical studies on trust and credibility in the use of WHI. The article seeks to present a profile of the research conducted on trust and credibility in WHI seeking, to identify the factors that impact judgments of trustworthiness and credibility, and to explore the role of demographic factors affecting trust formation. On this basis, it aimed to identify the gaps in current knowledge and to propose an agenda for future research. Methods: A systematic literature review was conducted. Searches were conducted using a variety of combinations of the terms WHI, trust, credibility, and their variants in four multi-disciplinary and four health-oriented databases. Articles selected were published in English from 2000 onwards; this process generated 3827 unique records. After the application of the exclusion criteria, 73 were analyzed fully. Results: Interest in this topic has persisted over the last 15 years, with articles being published in medicine, social science, and computer science and originating mostly from the United States and the United Kingdom. Documents in the final dataset fell into 3 categories: (1) those using trust or credibility as a dependent variable, (2) those using trust or credibility as an independent variable, and (3) studies of the demographic factors that influence the role of trust or credibility in WHI seeking. There is a consensus that website design, clear layout, interactive features, and the authority of the owner have a positive effect on trust or credibility, whereas advertising has a negative effect. With regard to content features, authority of the author, ease of use, and content have a positive effect on trust or credibility formation. Demographic factors influencing trust formation are age, gender, and perceived health status. Conclusions: There is considerable scope for further research. This includes increased clarity of the interaction between the variables associated with health information seeking, increased consistency on the measurement of trust and credibility, a greater focus on specific WHI sources, and enhanced understanding of the impact of demographic variables on trust and credibility judgments.

Trust and Credibility in Web-Based Health Information: A Review and Agenda for Future Research

PurposeTo measure the association between patient financial strain and symptom burden and quality of life (QOL) for patients with new diagnoses of lung or colorectal cancer.Patients and MethodsPatients participating in the Cancer Care Outcomes Research and Surveillance study were interviewed about their financial reserves, QOL, and symptom burden at 4 months of diagnosis and, for survivors, at 12 months of diagnosis. We assessed the association of patient-reported financial reserves with patient-reported outcomes including the Brief Pain Inventory, symptom burden on the basis of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30, and QOL on the basis of the EuroQoL-5 Dimension scale. Multivariable linear regression models were fit for each outcome and cancer type, adjusting for age, race/ethnicity, sex, income, insurance, stage at diagnosis, and comorbidity.ResultsAmong patients with lung and colorectal cancer, 40% and 33%, respectively, reported limited finan...

Association of Financial Strain With Symptom Burden and Quality of Life for Patients With Lung or Colorectal Cancer

Cancer starts as a localised disease, which, if detected early, can often be treated successfully by removal of the primary tumour. A pernicious progression is the invasion of tumour cells into surrounding tissues, resulting in development of distant metastases. Because active migration of tumour cells is a prerequisite for tumour-cell invasion and metastasis, a pressing goal in tumour biology has been the elucidation of factors regulating the migratory activity of these cells. The most prominent regulatory factors are ligands to serpentine receptors-eg, chemokines and neurotransmitters. Many types of neurotransmitter receptors are expressed on tumour cells, supporting the theory that psychosocial factors are involved in the progression of cancer. Understanding how such receptors regulate migration and the availability of specific receptor antagonists could open up new avenues for chemoprevention of tumour-cell migration and metastatic development.

MacArthur scale of subjective social status.

Many Latinos in the U.S. experience structural barriers to health care. Social capital and its implications for health and access to health care among this group are not well understood by researchers. This study examined associations between social capital and breast and cervical cancer screening adherence among a sample of 394 predominately Puerto Rican and Dominican women. Data were collected at baseline from Latinas attending screening education programs in Buffalo, New York and New York City in 2011-2012. Social capital was higher among Latinas who were older, better educated, insured, and spoke English. In multivariable logistic regression, a one unit increase in social capital index score was associated with greater adherence to Pap test (OR = 1.61), clinical breast exam (OR = 1.47) and mammography screening (OR = 1.50). Social capital should be further explored as a strategy to facilitate breast and cervical cancer screening among underserved Latinas.

With the rise in the use of the Internet for health-related purposes, social networking sites (SNSs) have become a prominent platform for cancer communication and information exchange. Studies of cancer communication on SNS have mostly focused on understanding the quantity, content, quality, and user engagement (eg, likes and comments) with cancer-related information on SNS. There is less of an understanding of when and why people coping with cancer turn to SNS for cancer-related information, and how users appraise the credibility of cancer-related information obtained on SNS. In this study, we use data from in-depth qualitative interviews with 40 primary caregivers of pediatric patients with cancer to examine how cancer caregivers engage in information appraisal and credibility assessment of cancer-related information obtained on SNS. Findings show that cancer caregivers turned to SNS for cancer-related information because information on SNS was immediate, targeted in response to specific caregiver questions and concerns, and tailored to the specific information needs of cancer caregivers. Cancer caregivers evaluated the credibility of cancer-related information obtained on SNS through assessment of the SNS user who posted the information, frequency the same information was shared, and external corroboration. Findings have important implications for cancer communication and information interventions and point to elements of SNS cancer communication that can be integrated into health professional-facilitated communication and cancer information strategies.

Deciphering the Signal From the Noise: Caregivers' Information Appraisal and Credibility Assessment of Cancer-Related Information Exchanged on Social Networking Sites.

Caregivers of terminally ill patients are at risk for anxiety, depression, and social isolation. Social support from friends, family members, neighbors, and health care professionals can potentially prevent or mitigate caregiver strain. While previous research documents the importance of social support in helping end-of-life caregivers cope with caregiving demands, little is known about differences in social support experiences among caregivers at different life course stages. Using life course theory, this study analyzes data from in-depth interviews with 50 caregivers of patients enrolled in hospice services to compare barriers to mobilizing social support among caregivers at two life course stages: midlife caregivers caring for parents and older adult caregivers caring for spouses/partners. Older adult caregivers reported different barriers to mobilizing social support compared with midlife caregivers. Findings enhance the understanding of how caregivers' life course stage affects their barriers to mobilization of social support resources.
