Purpose Internet support group (ISG) members benefit from receiving social support and, according to the helper therapy principle, by providing support to others. To test the mental health benefits of providing support to others, this trial compared the efficacy of a standard ISG (S-ISG) and an enhanced prosocial ISG (P-ISG). Methods A two-armed randomized controlled trial with 1-month pretest and post-test assessments was conducted with women (N = 184) diagnosed in the past 36 months with nonmetastatic breast cancer who reported elevated anxiety or depression. Women were randomly assigned to either the S-ISG or P-ISG condition. Both conditions included six professionally facilitated live chat sessions (90-minute weekly sessions) and access to an asynchronous discussion board; P-ISG also included structured opportunities to help and encourage others. Results Relative to the S-ISG, participants in the P-ISG condition exhibited more supportive behaviors (emotional, informational, and companionate support), posted more messages that were other-focused and fewer that were self-focused, and expressed less negative emotion (P < .05). Relative to the S-ISG, participants in the P-ISG condition had a higher level of depression and anxiety symptoms after the intervention (P < .05). Conclusion Despite the successful manipulation of supportive behaviors, the P-ISG did not produce better mental health outcomes in distressed survivors of breast cancer relative to an S-ISG. The prosocial manipulation may have inadvertently constrained women from expressing their needs openly, and thus, they may not have had their needs fully met in the group. Helping others may not be beneficial as a treatment for distressed survivors of breast cancer.
Minority participation in HIV clinical trials research is critical to understanding the impact of medications or behavioral interventions, but little is known about gender differences in perceptions of participation. We surveyed 50 minority HIV+ patients from an urban clinic to assess perceived risks/benefits of clinical trial research participation and used innovative marketing methods to analyze results. Perceptual mapping and vector message-modeling, a method that creates 3-D models representing how groups conceptualize elements, were used to assess how male and female participants could be motivated to participate. Results showed men farther away from participation and more concerned with HIV disclosure and experimentation than women. Men expressed distrust of the medical system, doubted HIV's origin, and knew less about research implementation. Women were closer to participation in both behavior and medical trials and perceived medication issues as more significant, including fear of losing medication stability, medications not working, being in the placebo group, and experiencing side effects. Vector modeling shows that messages would need to focus on different aspects of clinical research for men and women and that interventions aimed at minority HIV+ patients to encourage clinical trial participation would need to be targeted to their unique perceptions. Understanding gender perceptions of HIV clinical research has significant implications for targeting messages to increase minority participation.
This study describes patient social networks within a new hemodialysis clinic and models the association between social network participation and kidney transplantation. Survey and observational data collected between August 2012 and February 2015 were used to observe the formation of a social network of 46 hemodialysis patients in a newly opened clinic. Thirty-two (70%) patients formed a social network, discussing health (59%) and transplantation (44%) with other patients. While transplant-eligible women participated in the network less often than men (56% vs. 90%, p = 0.02), women who participated discussed their health more often than men (90% vs. 45.5%, p = 0.02). Patients in the social network completed a median of two steps toward transplantation compared with a median of 0 for socially isolated patients (p = 0.003). Patients also completed more steps if network members were closely connected (β = 2.23, 95% confidence interval [CI] 0.16-4.29, p = 0.03) and if network members themselves completed more steps (β = 2.84, 95% CI 0.11-5.57, p = 0.04). The hemodialysis clinic patient social network had a net positive effect on completion of transplant steps, and patients who interacted with each other completed a similar number of steps.
Objectives Radiological terror presents a real threat, but little is known about how low-income, urban African Americans may respond to such threats. The aim of this study was to understand the unique challenges of this group and to explore their knowledge of what a “dirty bomb” is, their intended behaviors should one occur, and their barriers to complying with “shelter in place” recommendations. Methods Thirty-seven 18–65-year-olds who were users of community centers in disadvantaged areas participated in 3 focus groups in Philadelphia. Results were analyzed by using the Krueger method of analyzing narrative text. Results The responses highlighted little knowledge or concern about a dirty bomb. Lack of trust in local authorities was expressed, with participants indicating that they did not feel their needs were addressed. While shelter in place was understood, most said they would still check on family or talk with others to get the “whole truth” because the most trusted information sources were neighbors and community leaders. Conclusion Our results indicate that a risk communication intervention for urban minorities may support desirable behaviors in the event of a dirty bomb, but successful communication will require establishing a local leader as a spokesperson to convince people of the importance of sheltering in place.
The proportion of women with unilateral breast cancer and no familial or genetic risk factors who elect contralateral prophylactic mastectomy (CPM) has grown dramatically, even in the absence of clear data demonstrating improved outcomes. To further extend the literature that addresses treatment decision-making, qualitative interviews were conducted with eleven women who considered CPM. A social ecological model of breast cancer treatment decision-making provided the conceptual framework, and grounded theory was used to identify the cognitive, psychosocial, and emotional influences motivating treatment choice. This research identified five themes that give context to women's decision-making experience: (1) variability in physician communication, (2) immediacy of the decision, (3) meaning of being proactive about treatment, (4) meaning of risk, and (5) women's relationship with their breasts. The results suggest that greater emphasis should be placed on a more nuanced understanding of patients' emotional reaction to breast cancer and managing the decision-making environment.
Preventive health messages are often tailored to reach broad sociodemographic groups. However, within groups, there may be considerable variation in perceptions of preventive health practices, such as colorectal cancer screening. Segmentation analysis provides a tool for crafting messages that are tailored more closely to the mental models of targeted individuals or subgroups. This study used cluster analysis, a psychosocial marketing segmentation technique, to develop a typology of colorectal cancer screening orientation among 102 African American clinic patients between the ages of 50 and 74 years with limited literacy. Patients were from a general internal medicine clinic in a large urban teaching hospital, a subpopulation known to have high rates of colorectal cancer and low rates of screening. Preventive screening orientation variables included the patients' responses to questions involving personal attitudes and preferences toward preventive screening and general prevention practices. A k-means cluster analysis yielded three clusters of patients on the basis of their screening orientation: ready screeners (50.0%), cautious screeners (30.4%), and fearful avoiders (19.6%). The resulting typology clearly defines important subgroups on the basis of their preventive health practice perceptions. The authors propose that the development of a validated typology of patients on the basis of their preventive health perceptions could be applicable to a variety of health concerns. Such a typology would serve to standardize how populations are characterized and would provide a more accurate view of their preventive health-related attitudes, values, concerns, preferences, and behaviors. Used with standardized assessment tools, it would provide an empirical basis for tailoring health messages and improving medical communication.
Objective: Designing salient digital health interventions requires theoreticallybased formative research and user-center design with stakeholder input throughout impacting content and technology design. mychoice is a theory-based, stakeholderguided digital health tool to improve clinical trial informed decision making, particularly among African American patients.Methods: mychoice was developed by (1) mixed-methods formative research, including in-depth interviews (n=16) and surveys (N=41) with African American cancer patients who had and had not participated in a clinical trial; (2) e-tool design process including perceptual mapping analysis to prioritize messages, multi-disciplinary team and stakeholder input; and (3) iterative production and user testing. Results:Interview findings showed that clinical trial participants expressed more positive attributes about and an openness to consider clinical trials, even though they expressed common concerns such as "fear of being a guinea pig". Survey results indicated that clinical trial participants expressed they had been given information to make the decision (P = .001), while those who had not more frequently reported (P > .001) that no one had talked to them about trials. Perceptual mapping indicated that values such as "helping find a cure" or "value to society" had little resonance to those who had not participated, providing message strategy for prototype development.User testing of the tool resulted in modifications; the most significant was the adaptation to a multi-cultural version. Conclusions:With the promise of digital health interventions, theory-guided, usercentered and best practice development is critical and mychoice serves as an example of the application of these principles.
Potential terror events such as "dirty bombs" could have significant public health effects, but little is known about how low-literacy populations perceive dirty bombs, their trust in public health or government officials to provide credible information, and their willingness to comply with recommended actions. We surveyed 50 low-literacy adults from a large urban center; they were mostly members of ethnic minority groups. We used unique social marketing methods-perceptual mapping and vector message modeling-to create 3-dimensional models that reflected respondents' knowledge of what a dirty bomb is, their intended behaviors should one occur, and their concerns about complying with "shelter in place" recommendations. To further understand individual variations in this at-risk group, a k-means cluster analysis was used to identify 3 distinct segments, differing on trust of local authorities and their emergency response, willingness to comply with emergency directives, and trust of information sources. Message strategies targeting each segment were developed to focus on concepts important to moving the groups toward a "shelter in place" behavior, revealing key differences in how best to communicate with risk communication. We discuss how these methods helped elucidate specific differences in each segment's understanding of and likely response during the event of a "dirty bomb" and how these techniques can be used to create more effective message strategies targeted to these groups.
