Seeking information about one's health is increasingly documented as a key coping strategy in health-promotive activities and psychosocial adjustment to illness. In this article, the authors critically examine the scientific literature from 1982 to 2006 on the concept of health information—seeking behavior (HISB) to determine its level of maturity and clarify the concept's essential characteristics. A principle-based method of concept analysis provides the framework for exploring the nature of HISB. The authors reviewed approximately 100 published articles and five books reporting on HISB. Although HISB is a popular concept used in various contexts, most HISB definitions provide little insight into the concept's specific meanings. The authors describe the concept's characteristics, contributing to a clearer understanding of HISB, and discuss operationalizations, antecedents, and outcomes of HISB. Such an analysis of HISB might guide further theorizing on this highly relevant concept and assist health care providers in designing optimal informational interventions.

Having an understanding of the roles that caregivers play in the oncology setting may assist health care professionals in supporting caregivers with these tasks, and targeting services toward those most in need.

Objectives The recognition that a partner or caregiver is typically the patient's primary support person and is also deeply affected by the cancer diagnosis has prompted efforts to document their unmet supportive care needs. This review aimed to: (1) quantify the prevalence of unmet needs reported by partners and caregivers, (2) categorise their unmet needs by domain and (3) identify the main variables associated with reporting more unmet needs. Methods Manuscripts were identified through systematically searching electronic databases, checking the reference lists of retrieved publications, online searching of key journals and contacting researchers in this field. Results Unmet need items across 29 manuscripts were clustered into six domains: comprehensive cancer care (prevalence 1.1%–96%), emotional and psychological (3%–93.2%), partner or caregiver impact and daily activities (2.8%–79%), relationship (3.7% and 58%), information (2.2%–86%) and spiritual (2%–43%). Studies of caregivers of palliative care or terminal patients often reported a higher prevalence of unmet needs than studies of caregivers of cancer survivors. Variables associated with higher unmet needs included being female, not being the spouse of the patient, having lower social support or reporting distress. Conclusions Despite the ability to classify unmet needs within broad domains, quantification of unmet needs was challenging. This was mainly due to the diversity in methods used across studies (eg, different measures, variability in conceptualisation of unmet needs, etc). Rigorous, context-specific, longitudinal studies that use validated measures are needed to benefit future intervention research.
