Psychological, Behavioral, and Immune Changes After a Psychological Intervention: A Clinical Trial

PURPOSE This randomized clinical trial tests the hypothesis that a psychological intervention can reduce emotional distress, improve health behaviors and dose-intensity, and enhance immune responses. PATIENTS AND METHODS We studied 227 women who were surgically treated for regional breast cancer. Before adjuvant therapy, women completed interviews and questionnaires assessing emotional distress, social adjustment, and health behaviors. A 60-mL blood sample was drawn for immune assays. Patients were randomly assigned to either the intervention group or assessment only group. The intervention was conducted in small patient groups, with one session per week for 4 months. The sessions included strategies to reduce stress, improve mood, alter health behaviors, and maintain adherence to cancer treatment and care. Reassessment occurred after completion of the intervention. RESULTS As predicted, patients receiving the intervention showed significant lowering of anxiety, improvements in perceived social support, improved dietary habits, and reduction in smoking (all P <.05). Analyses of adjuvant chemotherapy dose-intensity revealed significantly more variability (ie, more dispersion in the dose-intensity values) for the assessment arm (P <.05). Immune responses for the intervention patients paralleled their psychological and behavioral improvements. T-cell proliferation in response to phytohemagglutinin and concanavalin A remained stable or increased for the Intervention patients, whereas both responses declined for Assessment patients; this effect was replicated across three concentrations for each assay (all P <.01). CONCLUSION These data show a convergence of significant psychological, health behavior, and biologic effects after a psychological intervention for cancer patients.

Psychologic Intervention Improves Survival for Breast Cancer Patients A Randomized Clinical Trial

The question of whether stress poses a risk for cancer progression has been difficult to answer. A randomized clinical trial tested the hypothesis that cancer patients coping with their recent diagnosis but receiving a psychologic intervention would have improved survival compared with patients who were only assessed.

Traumatic Stress, Perceived Global Stress, and Life Events: Prospectively Predicting Quality of Life in Breast Cancer Patients.

The authors investigated the relationship between stress at initial cancer diagnosis and treatment and subsequent quality of life (QoL). Women (n = 112) randomized to the assessment-only arm of a clinical trial were initially assessed after breast cancer diagnosis and surgery and then reassessed at 4 months (during adjuvant treatment) and 12 months (postadjuvant treatment). There were 3 types of stress measured: number of stressful life events (K. A. Matthews et al., 1997), cancer-related traumatic stress symptoms (M. J. Horowitz, N. Wilner, & W. Alvarez, 1979), and perceived global stress (S. Cohen, T. Kamarck, & R. Mermelstein, 1983). Using hierarchical multiple regressions, the authors found that stress predicted both psychological and physical QoL (J. E. Ware, K. K. Snow, & M. Kosinski, 2000) at the follow-ups (all ps < .03). These findings substantiate the relationship between initial stress and later QoL and underscore the need for timely psychological intervention.

Strategies Used in Coping With a Cancer Diagnosis Predict Meaning in Life for Survivors

The search for meaning in life is part of the human experience. A negative life event may threaten perceptions about meaning in life, such as the benevolence of the world and ones sense of harmony and peace. The authors examined the longitudinal relationship between womens coping with a diagnosis of breast cancer and their self-reported meaning in life 2 years later. Multiple regression analyses revealed that positive strategies for coping predicted significant variance in the sense of meaning in life--feelings of inner peace, satisfaction with ones current life and the future, and spirituality and faith--and the absence of such strategies predicted reports of loss of meaning and confusion (ps < .01). The importance and process of finding meaning in the context of a life stressor are discussed.

PTSD diagnoses, subsyndromal symptoms, and comorbidities contribute to impairments for breast cancer survivors†

The clinical importance of posttraumatic stress disorder (PTSD) symptomatology for cancer patients is unclear. The association between the magnitude of cancer-related PTSD symptoms, comorbidity, and functioning is tested. Breast cancer patients (N = 74) were assessed at diagnosis/surgery, followed, and screened for cancer-related PTSD 18 months later. Participants then completed diagnostic interviews and PTSD (n = 12), subsyndromal PTSD (n = 5), and no symptom (n = 47) patient groups were identified. Posttraumatic stress disorder cases were distinguished by having experienced violent traumas and anxiety disorders predating cancer, whereas subsyndromal cases were not. Also, longitudinal data show that PTSD covarys with poorer functioning and lower quality of life among breast cancer survivors. Both PTSD and subsyndromal PTSD were associated with employment absenteeism and the seeking of mental health services.

Assessing Stress in Cancer Patients A Second-Order Factor Analysis Model for the Perceived Stress Scale

Using the Perceived Stress Scale (PSS), perceptions of global stress were assessed in 111women following breast cancer surgery and at 12 and 24 months later. This is the first study to factor analyze the PSS. The PSS data were factor analyzed each time using exploratory factor analysis with oblique direct quartimin rotation. Goodness-of-fit indices (root mean square error of approximation [RMSEA]), magnitude and pattern of factor loadings, and confidence interval data revealed a two-factor solution of positive versus negative stress items. The findings, replicated across time, also indicate factor stability. Hierarchical factor analyses supported a second-order factor of “perceived stress.” This alternative factor model of the PSS is presented along with observations regarding the measure’s use in cancer research.

RCT of a psychological intervention for patients with cancer: I. mechanisms of change.

Little is known about the therapeutic processes contributing to efficacy of psychological interventions for patients with cancer. Data from a randomized clinical trial yielding robust biobehavioral and health effects (B. L. Andersen et al., 2004, 2007) were used to examine associations between process variables, treatment utilization, and outcomes. Novel findings emerged. Patients were highly satisfied with the treatment, but their higher levels of felt support (group cohesion) covaried with lower distress and fewer symptoms. Also, specific treatment strategies were associated with specific outcomes, including lower distress, improved dietary habits, reduced symptomatology, and higher chemotherapy dose intensity. These data provide a comprehensive test of multiple therapeutic processes and mechanisms for biobehavioral change with an intervention including both intensive and maintenance phases.

Measuring meaning in life following cancer.

Meaning in life is a multi-faceted construct that has been conceptualized in diverse ways. It refers broadly to the value and purpose of life, important life goals, and for some, spirituality. We developed a measure of meaning in life derived from this conceptualization and designed to be a synthesis of relevant theoretical and empirical traditions. Two samples, all cancer patients, provided data for scale development and psychometric study. From exploratory and confirmatory factor analyses the Meaning in Life Scale (MiLS) emerged, and includes four aspects: Harmony and Peace, Life Perspective, Purpose and Goals, Confusion and Lessened Meaning, and Benefits of Spirituality. Supporting data for reliability (internal consistency, test–retest) and construct validity (convergent, discriminant, individual differences) are provided. The MiLS offers a theoretically based and psychometrically sound assessment of meaning in life suitable for use with cancer patients.

The gynecologic oncology consult: symptom presentation and concurrent symptoms of depression and anxiety.

OBJECTIVE: To detail the relationship of gynecologic symptoms and sociodemographic variables to depression and anxiety reports among women who were referred to gynecologic oncologists for evaluation. METHODS: Consecutive patients (N = 151) from an National Cancer Institute–designated comprehensive cancer center were accrued and participated on the day of consultation. Patients completed measures assessing depression (Center for Epidemiological Studies Depression Scale) and anxiety (Beck Anxiety Inventory) symptoms, common gynecologic signs/symptoms, and sociodemographic characteristics. Patients were followed up and subsequent diagnoses yielded 73 (48%) cancer and 78 (52%) benign cases. RESULTS: Descriptive analyses revealed that the cancer group was significantly older (52 versus 45 years) than the benign group, and variables correlated with age also differed significantly, with the cancer sample more likely to be postmenopausal, unemployed, and if employed, working fewer hours per week. Importantly, the groups did not differ on reports of depressive, anxiety, or gynecologic symptoms. Hierarchical multiple regression analyses, collapsing across groups, yielded significant correlates of emotional distress. Women who were older, without a spouse/partner, and who had more gynecologic symptoms had higher levels of both depressive and anxiety symptoms. Among the women who did have a partner, those with relationships of longer duration reported lower levels of depression/anxiety CONCLUSION: Reports of clinically significant depressive (42%) and anxiety symptoms (30%) were high. The number of gynecologic symptoms was reliably correlated with emotional distress. Age and absence of partner may have conferred added vulnerability. For those women with partners, lengthier relationships appeared to offer protection from both depressive and anxiety symptoms. LEVEL OF EVIDENCE: III

Screening and identification of depression among patients with coronary heart disease and congestive heart failure.

Depression occurring concurrently with cardiovascular diseases is associated with poor outcomes. Several review articles have examined the link between established indices of depression and prognosis in individuals with known coronary heart disease (CHD). These studies have demonstrated relatively consistent results and suggest an important connection between cardiovascular morbidity and mortality in patients with depressive symptoms or major depression. This article discusses the current best practices for the screening, identification, and treatment of depression in patients with CHD and coronary heart failure, as well as the financial aspects associated with care management.
