Measurement of salivary cortisol can provide important information about hypothalamic-pituitary-adrenal (HPA) axis activity under normal conditions and in response to stress. However, there are many variables relating to the measurement of cortisol in saliva which may introduce error and therefore may render difficult the comparison and interpretation of data between, and within, laboratories. This review addresses the effects of gender, age, time and location of sampling, units of measurement, assay conditions and compliance with the protocol, all of which have the potential to impact upon the precision, accuracy and reliability of salivary cortisol measurements in the literature. Some of these factors are applicable to both adults and children, but the measurement of salivary cortisol in children introduces aspects of unique variability which demand special attention. The specific focus of this review is upon the somewhat neglected area of methodological variability of salivary cortisol measurement in children. In addition to these methodological issues, the review highlights the use of salivary cortisol measurements to provide information about HPA axis dysfunction associated with psycho- and patho-physiological conditions in children. Novel applications for salivary cortisol measurements in future research into HPA axis activity in children are also discussed.

Results show that greater quality of social support is associated with lower cortisol concentrations in women with metastatic breast cancer, which is indicative of healthier neuroendocrine functioning. These results may have clinical implications in the treatment of breast cancer.

OBJECTIVE: This study was initiated by breast cancer survivors living in a rural community in California. They formed a partnership with academic researchers to develop and evaluate a low‐cost, community‐based Workbook‐Journal (WBJ) for improving psychosocial functioning in geographically and economically isolated women with primary breast cancer. DESIGN: A randomized controlled trial was used to compare the WBJ intervention plus educational materials to educational materials alone (usual care). SETTING: One rural cancer center and several private medical, surgical, and radiation oncology practices in 7 rural counties in the Sierra Nevada Foothills of California. PARTICIPANTS: One hundred women with primary breast cancer who were either within 3 months of diagnosis or within 3 months of completing treatment. INTERVENTION: A community‐initiated, theoretically‐based Workbook‐Journal, designed by rural breast cancer survivors and providers as a support group alternative. It included compelling personal stories, local rural resources, coping strategies, and messages of hope. RESULTS: Community recruiters enrolled 83% of the women referred to the study. Retention at 3‐month follow‐up was 98%. There were no main effects for the WBJ. However, 3 significant interactions suggested that women who were treated in rural practices reported decreased fighting spirit and increased emotional venting and posttraumatic stress disorder symptoms if they did not receive the WBJ. Among women who receive the WBJ, 74% felt emotionally supported. CONCLUSIONS: This community‐based Workbook‐Journal may be an effective psychosocial intervention for rural, isolated, and low‐income women with breast cancer. Community involvement was essential to the success of this project.

This study examined distress, coping, and group support among a sample of rural women who had been recently diagnosed with breast cancer. We recruited 100 women who had been diagnosed with primary breast cancer at one of two time points in their medical treatment: either within a window up to 3 months after their diagnosis of breast cancer, or within 6 months after completing medical treatment for breast cancer. Their mean age was 58.6 years (SD = 11.6), and 90% were of white/European American ethnicity. Women completed a battery of demographic and psychosocial measures prior to being randomized into a psychoeducational intervention study, and then again 3 months later at a follow-up assessment. The focus of this article is on the women's self-reported psychosocial status at baseline. Many of the women experienced considerable traumatic stress regarding their breast cancer. However, this distress was not reflected in a standard measure of mood disturbance that is frequently used in intervention research (the Profile of Mood States). The average woman considered her diagnosis of breast cancer to be among the four most stressful life events that she had ever experienced. Also, women on average reported a high level of helplessness/hopelessness in coping with their cancer. On average, women felt that they "often" (but not "very often") received instrumental assistance, emotional support, and informational support. Women varied considerably in which kind of social group provided them with the most support, with as many reporting that they found the greatest support in spiritual/church groups or within their family units as with breast or general cancer groups. These results suggest that among these rural women with breast cancer, distress with the diagnosis of breast cancer must be carefully assessed, as women who are highly distressed about their breast cancer may not report general mood disturbance. Furthermore, the kinds of groups that rural women with breast cancer experience as most supportive need to be identified so that psychosocial interventions can be matched to breast cancer patients' individual needs.

This study examined psychosocial influences on hypothalamic-pituitary-adrenal axis activity in 105 4-year-old children transitioning to primary school. Measuring before, during, and after school transition over a period of up to 12 months, salivary cortisol was assessed on awakening and early evening. Parents reported child temperament and teachers recorded adaptive behavior. Whilst cortisol at awakening and early evening increased from baseline to school transition, effects were not significant. A significant decrease occurred between transition and follow-up and from baseline to follow-up for both awakening and evening cortisol. Poorer effortful control was associated with high morning and steeper diurnal slope of cortisol at transition whilst surgency/extroversion was associated individually with greater morning and evening cortisol at transition and adaptation. Greater increase in internalizing social isolation during the first 6 months of school in more surgent/extrovert children predicted higher morning and evening cortisol at follow-up. This study is the first to explore these adaptive relationships over a 12-month period and supports social isolation over time as a key element in developmental endocrine activation.
