Negative subjective appraisals of symptoms may influence both insomnia and fatigue severity, but this relationship has not been examined among those with MS. The relationship between insomnia symptoms and both physical and cognitive fatigue were examined. Health-related self-efficacy, fatigue catastrophization, and rumination were examined as potential mediators of the relationship between insomnia symptoms and fatigue. Participants diagnosed with MS (N = 114) were recruited from hospital and community settings in a large metropolitan city. Participants completed self-report questionnaires including: Modified Fatigue Impact, Insomnia Severity Index, MS Quality of Life Questionnaire-54, Fatigue Catastrophizing Scale, Multidimensional Health Locus of Control Scale, and the Rumination-Reflection Questionnaire. Two multiple mediation analyses were performed using bootstrapping techniques, exam...

The purpose of this study was to apply the theoretical model of strength and vulnerability integration (SAVI; Charles, 2010) to understand age-related patterns in emotional experiences and cancer appraisals among people diagnosed with colorectal cancer. Methods: Individuals recently diagnosed with colorectal cancer (N 139; 28 – 89 years-old) completed measures of positive and negative affect, depressive symptoms, and appraisals about cancer at four time points: baseline (prior to colorectal cancer surgery), 6-, 12-, and 18-months postsurgery. Multilevel modeling examined changes in affective experience and appraisals over time, across age, and the interaction of time by age. Results: Negative affect decreased more rapidly over time among older adults than younger adults, p .05, but positive affect was reasonably stable and unrelated to age. Depressive symptoms were also fairly stable over time, but consistently higher among younger adults, p .01. Older age was significantly related to lower threat appraisals and greater levels of challenge, p .01. Threat, but not challenge, mediated the age-by-time interaction predicting negative affect. Conclusions: Older age was related to lower levels of depressive symptoms and negative affect. Older adults also reported more adaptive appraisals of their cancer, which accounted for their more rapid decline in negative affect compared to younger adults. Overall, SAVI is a useful model for understanding age-related patterns in emotional well-being and appraisals in the context of colorectal cancer.

Women with confirmed LS (N = 128) were recruited from a high-risk of cancer registry and completed a one-time self-report questionnaire. Women who reported greater intolerance of uncertainty and more trust in their physician reported less cancer worry interference compared to women who had greater intolerance of uncertainty and less trust in their physician, who reported the highest worry interference, b =-1.39, t(99) =-2.27, p = .03. No moderation effect of trust in physician was found for anxiety or depression. Trust in one's physician buffered the impact of high intolerance of uncertainty on cancer worry interference, underscoring the need for supportive provi-der–patient relationships, particularly for LS patients.

Methods Twenty-one patients with pelvic floor dyssynergia were randomized to either (1) an AB arm, where patients learned to isolate the anal sphincter using an electromyog-raphy probe, or (2) a BC arm that controlled for the nonspecific effects of biofeedback, where patients learned to relax trapezius or temporalis muscles with EMG feedback. Both treatments were delivered by registered nurses for six sessions. Prior to randomization and post-treatment, patients completed the validated Constipation Severity Instrument and two measures of quality of life (QOL), the Irritable Bowel Syndrome-QOL, and the SF-36. Generalized estimating equations examined the within-group and between-group differences over time. Results Pre-and post-treatment data were obtained for six AB and nine BC patients. AB patients' overall constipation severity scores decreased by 35.5% (vs. 15.3%), and their obstructive defecation symptom scores decreased by 37.9% (vs. 19.7%) compared to BC. A similar pattern was shown on the IBS-QOL. On the SF-36 Mental Health Composite (MCS), AB scores improved 28.0% compared to BC scores, which worsened 12.7%. Those without (vs. with) a childhood sexual/physical abuse history showed improvement on the MCS post-biofeedback. Conclusions While our sample was statistically under-powered, AB produced clinical improvements in constipation severity and QOL.

We hypothesized that beliefs about mammography, cancer vulnerability, and attitudes toward the medical provider would mediate the relationship between sexual orientation and plans to obtain breast cancer screening. Methods: Women in this study participated in one of two larger clinical trials of breast cancer risk counseling methods. All participants completed questionnaires about breast cancer screening attitudes at baseline and at a 6-month follow-up. Results: Logistic regression analyses, controlling for age, education, and race, revealed that baseline negative beliefs about mammography, lower levels of provider trust, and less perceived risk of breast cancer significantly mediated the relationship between sexual orientation and 6-month intentions to obtain a clinical breast examination (CBE) and mammography. Conclusions: These findings suggest that attitudes and beliefs about breast cancer, breast cancer screening, and medical providers impact lesbian/bisexual women's willingness to plan for CBE and mammography.

Moreover, although attachment and greater disclosure of sexual orientation have been associated with health outcomes, their associations in this population have been largely unexamined. The purpose of the present study was to investigate whether greater outness about one's sexual orientation significantly mediated the associations between anxious and avoidant attachment and illness intrusiveness among gay men with prostate cancer. Ninety-two gay and bisexual men who had received a diagnosis of prostate cancer in the past 4 years were recruited for the present study. Self-report questionnaires assessed demographic and medical variables, attachment, outness level and comfort, and illness intrusiveness. Bootstrapping procedures were used to assess for mediation. Results suggested significant associations between anxious attachment, outness comfort, and illness intrusiveness. Less comfort with outness significantly mediated the association between greater anxious attachment and more illness intrusiveness. Avoidant attachment was not significantly associated with illness intrusiveness. Findings support the mediating role of the subjective experience of being an out gay man in the association between anxious attachment and illness intrusiveness. These results suggest that facilitating greater comfort with outness would be beneficial for illness adjustment among gay men with prostate cancer whom have more anxious attachment styles.

We examined the relationships between perceived risk, cancer worry and screening behaviors among first-degree relatives (FDRs) of patients with familial gastric cancer. FDRs of patients diagnosed with familial gastric cancer with a non-informative genetic analysis were identified and contacted. Participants completed a telephone interview that assessed socio-demographic information, cancer risk perception, cancer worry, impact of worry on daily functioning, and screening behaviors. Twenty-five FDRs completed the telephone interview. Participants reported high levels of comparative and absolute cancer risk perception, with an average perceived lifetime risk of 54 %. On the other hand, cancer-related worry scores were low, with a significant minority (12 %) experiencing high levels of worry. Study participants exhibited high levels of confidence (median = 70 %) in the effectiveness of screening at detecting a curable cancer. Participants that had undergone screening in the past showed significantly lower levels of cancer-related worry compared to those that had never undergone screening. In conclusion, individuals at high-risk for gastric cancer perceived a very high personal risk of cancer, but reported low levels of cancer worry. This paradoxical result may be attributed to participants' high levels of confidence in the effectiveness of screening. These findings highlight the importance for clinicians to discuss realistic risk appraisals and expectations towards screening with unaffected members of families at risk for gastric cancer, in an effort to help mitigate anxiety and help with coping.

Observational survey study. Consultation service for United States health care providers. Thirty-one human immunodeficiency virus (HIV)-infected patients who had received previous treatment with at least two protease inhibitor--or nonnucleoside reverse transcriptase inhibitor--based regimens and had a viral load of at least 1000 copies/ml. Patients whose providers consulted Warmline regarding antiretroviral salvage regimens were identified through a review of telephone calls from January-July 2001. Virologic and immunologic outcomes were determined for patients who had received a regimen containing either ritonavir and indinavir or ritonavir and amprenavir. Primary outcomes were percentages of patients with a viral load less than 500 copies/ml at 3 and 6 months and changes in log10 viral load and CD4+ cell count at 3 and 6 months compared with baseline values. By using intent-to-treat analysis, a viral load less than 500 copies/ml was achieved in 35% of the 31 patients at 3 months and in 32% of them at 6 months. By using as-treated analysis, this outcome was achieved in 48% of 23 patients who continued therapy at 3 months and in 59% of 17 patients who continued therapy at 6 months. At 3 months (23 patients) and 6 months (17 patients), respectively, changes in viral load were -1.7 log10 copies/ml (p<0.001) and -1.4 log10 copies/ml (p<0.001), and changes in CD4+ cell count were +99 cells/mm3 (p<0.001) and +95 mm3 (p=0.012), compared with baseline. Significant improvements in virologic and immunologic markers occurred in patients heavily experienced with antiretroviral therapy after starting dual-protease inhibitor treatment regimens. Salvage therapy guided by Warmline consultation appears to be beneficial for this patient population with limited treatment options.
