BACKGROUND

Online health communities (OHCs) provide patients and survivors of ovarian cancer (OvCa) and their caregivers with help beyond traditional support channels, such as health care providers and clinicians. OvCa OHCs promote connections and exchanges of information among users with similar experiences. Users often exchange information, which leads to the sharing of resources in the form of web links. Although OHCs are important platforms for health management, concerns exist regarding the quality and relevance of shared resources. Previous studies have examined different aspects of resource-sharing behaviors, such as the purpose of sharing, the type of shared resources, and peer user reactions to shared resources in OHCs to evaluate resource exchange scenarios. However, there is a paucity of research examining whether resource-sharing behaviors can ultimately determine the relevance of shared resources.

OBJECTIVE

This study aimed to examine the association between OHC resource-sharing behaviors and the relevance of shared resources. We analyzed three aspects of resource-sharing behaviors: types of shared resources, purposes of sharing resources, and OHC users’ reactions to shared resources.

METHODS

Using a retrospective design, data were extracted from the National Ovarian Cancer Coalition discussion forum. The relevance of a resource was classified into three levels: relevant, partially relevant, and not relevant. Resource-sharing behaviors were identified through manual content analysis. A significance test was performed to determine the association between resource relevance and resource-sharing behaviors.

RESULTS

Approximately 48.3% (85/176) of the shared resources were identified as relevant, 29.5% (52/176) as partially relevant, and 22.2% (39/176) as irrelevant. The study established a significant association between the types of shared resources (<i>χ</i><sup>2</sup><sub>18</sub>=33.2; <i>P</i>&lt;.001) and resource relevance (through chi-square tests of independence). Among the types of shared resources, health consumer materials such as health news (<i>P</i>&lt;.001) and health organizations (<i>P</i>=.02) exhibited significantly more relevant resources. Patient educational materials (<i>P</i>&lt;.001) and patient-generated resources (<i>P</i>=.01) were more significantly associated with partially relevant and irrelevant resources, respectively. Expert health materials, including academic literature, were only shared a few times but had significantly (<i>P</i>&lt;.001) more relevant resources. A significant association (<i>χ</i><sup>2</sup><sub>10</sub>=22.9; <i>P</i>&lt;.001) was also established between the purpose of resource sharing and overall resource relevance. Resources shared with the purpose of providing additional readings (<i>P</i>=.01) and pointing to resources (<i>P</i>=.03) had significantly more relevant resources, whereas subjects for discussion and staying connected did not include any relevant shared resources.

CONCLUSIONS

The associations found between resource-sharing behaviors and the relevance of these resources can help in collecting relevant resources, along with the corresponding information needs from OvCa OHCs, on a large scale through automation. The results from this study can be leveraged to prioritize the resources required by survivors of OvCa and their caregivers, as well as to automate the search for relevant shared resources in OvCa OHCs.
