BACKGROUND: Stress management interventions can reduce symptoms of distress as well as modulate certain immune system components in persons infected with human immunodeficiency virus (HIV). These effects may occur in parallel with reductions in hypothalamic-pituitary-adrenal (HPA) axis hormones such as cortisol, which has been related in other work to a down-regulation of immune system components relevant to HIV infection. The present study tested the effects of a multimodal cognitive-behavioral stress management (CBSM) intervention on 24-hour urinary free cortisol levels and distressed mood in symptomatic HIV+ gay men. METHODS: Symptomatic HIV-infected gay men who were randomized to either a 10-week group-based CBSM intervention or a 10-week wait-list period provided psychological responses and urine samples pre-post intervention. RESULTS: Of the 59 participants providing matched questionnaire data, men assigned to CBSM (n = 40) showed significantly lower posttreatment levels of self-reported depressed affect, anxiety, anger, and confusion than those in the wait-list control group (n = 19). Among the 47 men providing urine samples (34 CBSM, 13 controls), those assigned to CBSM revealed significantly less cortisol output as compared to controls. At the individual level, depressed mood decreases paralleled cortisol reductions over this period across the entire sample. CONCLUSION: A time-limited CBSM intervention reduced distress symptoms and urinary free cortisol output in symptomatic HIV+ gay men and greater reductions in some aspects of distress, especially depressed mood, paralleled greater decreases in cortisol over the intervention period. If persisting stressors and depressed mood contribute to chronic HPA axis activation in HIV-infected persons, then interventions such as CBSM, which teaches them to relax, alter cognitive appraisals, use new coping strategies, and access social support resources, may decrease distress and depressed mood and normalize HPA axis functioning. 相似文献

BACKGROUND: Stress management interventions reduce distress symptoms and hypothalamic-pituitary-adrenal (HPA) axis hormones such as cortisol, which has been related to a down-regulation of immune system components relevant to the human immunodeficiency virus (HIV) infection. We previously showed that HIV+ men assigned to a 10-week cognitive behavioral stress management (CBSM) intervention showed more CD4+CD45RA+CD29+ lymphocytes, an indicator of immune system reconstitution, at a 6- to 12-month follow-up compared with controls. Here, we tested whether reductions in urinary cortisol output and depressed mood during the 10-week CBSM intervention period mediated its effects on this immune system reconstitution marker at follow-up. METHODS: Twenty-five HIV-infected men randomized to either a 10-week CBSM intervention or a wait-list control provided 24-h urine samples and psychological responses pre- to postintervention, which were related to changes in immune status over a 6- to 12-month follow-up period. RESULTS: Greater reductions in cortisol output and depressed mood during CBSM appeared to mediate the effects of this intervention on this indicator of immune system reconstitution over the 6- to 12-month follow-up period. Changes in mood were maintained over the follow-up period, although these did not add explanatory information beyond the cortisol and mood changes that were observed during the 10-week intervention period. These findings were not explained by the changes in medications or health behaviors during follow-up. CONCLUSION: A time-limited CBSM intervention may affect the rate of immune system reconstitution in HIV-infected men by modifying the stress of symptomatic disease. This intervention may work by decreasing depressed mood and normalizing HPA axis functioning. 相似文献

This study examined the effects of a 10-week cognitive-behavioral stress management (CBSM) intervention on dehydroepiandrosterone sulfate (DHEA-S) levels and the ratio of cortisol to DHEA-S (cortisol/DHEA-S), potential surrogate adrenal markers of HIV disease progression, in relation to alterations in mood and distress. HIV-seropositive men were randomized to either a group-based CBSM intervention (n = 43) or to a wait-list control group (n = 24), with both hormonal and distress measures assessed just prior to and immediately following the 10-week period. Results showed that CBSM buffers decreases in DHEA-S and increases in the cortisol/DHEA-S ratio. Further examination also revealed that changes in the cortisol/DHEA-S ratio were significantly and positively related to changes in total mood disturbance and perceived stress over time. These findings demonstrate that a short-term CBSM intervention can buffer against decrements in DHEA-S and increments in the cortisol/DHEA-S ratio among symptomatic, HIV-positive men, and that alterations in the cortisol/DHEA-S ratio move in concert with changes in mood and distress observed during CBSM. 相似文献

OBJECTIVE: We tested the effects of a 10-week group-based cognitive-behavioral stress management/expressive-supportive therapy intervention (CBSM+) and a time-matched individual psychoeducational condition for 330 women with AIDS reporting moderate to poor baseline quality of life (QOL). The goal of this study was to examine treatment effects on total QOL and 11 QOL domains from baseline to post-intervention follow-up. METHODS: Participants were assessed at baseline, randomized to a treatment condition (individual psychoeducation condition n=180, group-based CBSM+ condition n=150), participated in the intervention for 10 weeks and assessed again within 4 weeks following the intervention. QOL was measured using the Medical Outcomes Study-HIV-30. RESULTS: QOL scores increased over the course of both interventions for the total QOL score and three QOL domains: cognitive functioning, health distress and overall health perceptions. While women in the CBSM+ group condition showed a significant improvement in mental health QOL from pre- to post-intervention, women in the individual condition did not change. No changes were observed for energy/fatigue, health transition, single-item overall QOL, pain, physical well-being, role functioning or social functioning in either condition. CONCLUSION: Results suggest that group-based CBSM+ and individual psychoeducational interventions are effective at improving certain aspects of QOL and that group-based CBSM+ may be particularly effective at increasing QOL related to mental health in this population of women with AIDS. 相似文献

Background: One of the most common gynecologic conditions among HIV+ women is cervical dysplasia, the precancerous phase of cervical
cancer. Therefore, adherence to gynecology vi sits may be among the most important health care practices for HIV+ women. However,
no research has evaluated the psychosocial factors associated with health care practices among HIV+ women at risk for cervical
cancer.Purpose: This study examined the relationship between inhibited interpersonal coping style and adherence to primary care and obstetrics/gynecology
visits in HIV+ women with Human Papillomavirus (HPV) infection.Methods: Twenty-eight HIV-1 seropositive Black, non-Hispanic women underwent a psychosocial interview, blood draw, and gynecologic
examination. The Millon Behavioral Health Inventory was used to assess coping style. Medical chart review was used to assess
adherence to scheduled special immunology clinic visits for 24 months following study entry.Results: Results suggested that greater inhibited coping style significantly predicted greater nonadherence to clinic visits during
1-year (β = .45, p = .04) and 2-year (β =.58, p = .02) follow-up, even after controlling for the possible confounding effects
of recent depressed mood on adherence. Social support satisfaction did not mediate the relationship between inhibited coping
style and nonadherence.Conclusions: These findings suggest that interpersonal coping style assessment may be a useful tool in predicting adherence in HIV+ women
with HPV. Future research should assess the effect of psychosocial interventions on coping style, adherence, and cervical
dysplasia in HIV+ women with HPV.

Objective
The present pilot study was designed to test the effects of a 12-week group-based cognitive behavioral stress management (CBSM) intervention on stress, quality of life, and symptoms in chronic fatigue syndrome (CFS). We hypothesized that participants randomized to CBSM would report improvements in perceived stress, mood, quality of life, and CFS symptomatology from pre- to postintervention compared to those receiving a psychoeducational (PE) seminar control.Method
We recruited 69 persons with a bona fide diagnosis of CFS and randomized 44 to CBSM and 25 to PE. Participants completed the Perceived Stress Scale (PSS), Profile of Mood States (POMS), Quality of Life Inventory (QOLI), and a Centers for Disease Control (CDC)-based CFS symptom checklist pre- and postintervention.Results
Repeated measures analysis of variance revealed a significant Group×Time interaction for PSS, POMS-total mood disturbance (TMD), and QOLI scores, such that participants in CBSM evidenced greater improvements than those in PE. Participants in CBSM also reported decreases in severity of CFS symptoms vs. those in PE.Conclusions
Results suggest that CBSM is beneficial for managing distress, improving quality of life, and alleviating CFS symptom severity. 相似文献7.

OBJECTIVE: Risk for developing cervical neoplastic disease is greatly increased in women infected with oncogenic sexually transmitted human papillomaviruses (HPVs) and who have lowered cellular immunity due to coinfection with human immunodeficiency virus (HIV) infection. The majority of these individuals are low-income minority women. Factors associated with promotion of HPV to cervical neoplasia in HIV-infected populations include degree of immunosuppression as well as behavioral factors such as tobacco smoking and psychological stress. This study examined the effects of a cognitive behavioral stress management (CBSM) intervention on life stress and cervical neoplasia in HIV+ minority women. METHODS: Participants were 39 HIV+ African-American, Caribbean, and Hispanic women with a recent history of an abnormal Papanicolaou smear. Participants underwent colposcopic examination, psychosocial interview, and peripheral venous blood draw at study entry and 9 months after being randomly assigned to either a 10-week CBSM group intervention (n=21) or a 1-day CBSM workshop (n=18). RESULTS: Women assigned to the 10-week group-based CBSM intervention reported decreased perceived life stress and had significantly lower odds of cervical neoplasia over a 9-month follow-up. CBSM effects on life stress and neoplasia appeared independent of presence of neoplasia at study entry, HPV type, CD4+CD3+ cell count, HIV viral load, and substance use. Furthermore, CBSM intervention effects on cervical neoplasia were especially pronounced among women with residual life stress at follow-up. CONCLUSION: These findings suggest that stress management decreases perceived life stress and may decrease the odds of cervical neoplasia in women with HIV and a history of abnormal Papanicolaou smears. Although preliminary, these findings suggest the utility of stress management as a cancer prevention strategy in this high-risk population. 相似文献

BackgroundA diagnosis of breast cancer and treatment are psychologically stressful events, particularly over the first year after diagnosis. Women undergo many demanding and anxiety-arousing treatments such as surgery, radiation and chemotherapy. Psychosocial interventions that promote psychosocial adaptation to these challenges may modulate physiological processes (neuroendocrine and immune) that are relevant for health outcomes in breast cancer patients.MethodsWomen with Stages 1–3 breast cancer recruited 4–8 weeks after surgery were randomized to either a 10-week group-based cognitive behavioral stress management (CBSM) intervention or a 1-day psychoeducational control group and completed questionnaires and late afternoon blood samples at study entry and 6 and 12 months after assignment to experimental condition.ResultsOf 128 women initially providing psychosocial questionnaire and blood samples at study entry, 97 provided complete data for anxiety measures and cortisol analysis at all time points, and immune assays were run on a subset of 85 of these women. Those assigned to a 10-week group-based CBSM intervention evidenced better psychosocial adaptation (lower reported cancer-specific anxiety and interviewer-rated general anxiety symptoms) and physiological adaptation (lower cortisol, greater Th1 cytokine [interleukin-2 and interferon-γ] production and IL-2:IL-4 ratio) after their adjuvant treatment compared to those in the control group. Effects on psychosocial adaptation indicators and cortisol appeared to hold across the entire 12-month observation period. Th1 cytokine regulation changes held only over the initial 6-month period.ConclusionsThis intervention may have facilitated a “recovery or maintenance” of Th1 cytokine regulation during or after the adjuvant therapy period. Behavioral interventions that address dysregulated neuroendocrine function could play a clinically significant role in optimizing host immunologic resistance during a vulnerable period. 相似文献

ABSTRACTObjectives: The main aim was to test a causal relations model of the problem-focused and emotion-focused coping styles, depressed mood, and divergent thinking (DT) in older adults. It was hypothesized that both forms of coping would have a significant effect on predicting depressed mood, and that problem-focused coping and depressed mood would have a significant effect on DT. Method: Participants were 135 subjects with ages ranging between 55 and 84 years old, who took part in a personal interview and filled out several questionnaires. The statistical analysis included structural equations models (SEM).Results: The initial model led to a final model endorsed by the goodness of fit, composite reliability, and discriminant validity indexes. This model confirms a direct relationship between the two types of coping strategies and depressed mood (with the opposite sign), but not between rational coping and DT. Finally, depressed mood was also confirmed as a mediator variable between coping and DT. Conclusion: The type of coping is a clear predictor of mood in older adults. Advanced age decline is not necessarily translated into inefficacy in everyday problem solving especially in those who, through proble-focused coping, avoid depressed moods and maintain good levels of DT. 相似文献

OBJECTIVE: This study examined the effect of a cognitive-behavioral stress management (CBSM) intervention on emotional well-being and immune function among women in the months following surgery for early-stage breast cancer. METHOD: Twenty-nine women were randomly assigned to receive either a 10-week CBSM intervention (n=18) or a comparison experience (n=11). The primary psychological outcome measure was benefit finding. The primary immune function outcome measure was in vitro lymphocyte proliferative response to anti CD3. RESULTS: Women in the CBSM intervention reported greater perceptions of benefit from having breast cancer compared to the women in the comparison group. At 3-month follow-up, women in the CBSM group also had improved lymphocyte proliferation. Finally, increases in benefit finding after the 10-week intervention predicted increases in lymphocyte proliferation at the 3-month follow-up. CONCLUSION: A CBSM intervention for women with early-stage breast cancer facilitated positive emotional responses to their breast cancer experience in parallel with later improvement in cellular immune function. 相似文献

PurposeTo determine whether individuals with epilepsy who are depressed have different coping reactions, such as increased use of disengagement-type coping reactions, compared to those who are not.MethodsWe surveyed 200 patients with epilepsy and obtained demographic and clinical information. We used the Neurological Institute Disorders Depression Inventory for Epilepsy (NIDDI-E) to determine those patients who had a major depression (NIDDI-E score >15) and administered the Quality of Life in Epilepsy-10 Inventory (QOLIE-10), Beliefs About Medicines Questionnaire-Specific, Sheehan Disability Scale, a screening question for health literacy (“How confident are you filling out medical forms by yourself?”), and the Brief Coping with Problems Experienced (Brief-COPE). Using univariate analysis, we determined those demographic and clinical variables that were associated with depression. We also determined the coping reactions more frequently utilized by individuals with depression, and using multivariate analysis, determined whether those coping reactions retained statistical significance. We performed subgroup analysis of depressed epilepsy patients to determine whether coping reactions they preferentially utilized were associated with seizure frequency and quality of life.ResultsSeventy-one patients had a major depression while 128 did not. On univariate analysis, not driving, not working, higher seizure frequency, experiencing convulsions, poorer quality of life, and higher disability scores were significantly associated with major depression. These individuals used denial more often as a coping reaction. On multiple linear regression, the association between the use of denial and being depressed retained statistical significance. The mean denial coping scores were higher among depressed patients with more frequent seizures. However, this did not reach statistical significance.ConclusionIndividuals with epilepsy who have a major depression utilize denial more often as a coping reaction. Realizing this is of value to caregivers as they help patients deal with their stressful situation. This also provides additional impetus to more effectively and aggressively treatment depression in the epilepsy population. 相似文献

Stress-induced craving and stress reactivity may influence risk for substance use or relapse to use. Interventions designed to attenuate stress-induced craving and stress reactivity may serve as excellent adjuncts to more comprehensive treatment programs. The purpose of this study was to (1) tailor an existing, manualized, cognitive-behavioral stress management (CBSM) intervention for use in individuals with substance use disorders and (2) preliminarily evaluate the effects of the intervention using an experimental stress-induction paradigm. Twenty individuals were interviewed and then completed a psychological stress task, the Mental Arithmetic Task (MAT). After this, participants were assigned to either the CBSM intervention group or a nontreatment comparison group. Approximately 3 weeks later, participants completed a second MAT. In contrast to the comparison group, the CBSM group demonstrated significantly less stress-induced craving (p<.04) and stress (p<.02), and reported greater ability to resist urges to use (p<.02) after the second MAT. These findings are among the first to report on the use of an intervention to attenuate craving and stress reactivity among individuals with substance use disorders. Although preliminary, the findings suggest that systematic investigation of interventions specifically targeting stress management in individuals with substance use disorders should be undertaken. 相似文献

Background
Human immunodeficiency virus (HIV) treatment side effects have a deleterious impact on treatment adherence, which is necessary to optimize treatment outcomes including morbidity and mortality.Purpose
To examine the effect of the Balance Project intervention, a five-session, individually delivered HIV treatment side effects coping skills intervention on antiretroviral medication adherence.Methods
HIV+ men and women (N?=?249) on antiretroviral therapy (ART) with self-reported high levels of ART side effect distress were randomized to intervention or treatment as usual. The primary outcome was self-reported ART adherence as measured by a combined 3-day and 30-day adherence assessment.Results
Intent-to-treat analyses revealed a significant difference in rates of nonadherence between intervention and control participants across the follow-up time points such that those in the intervention condition were less likely to report nonadherence. Secondary analyses revealed that intervention participants were more likely to seek information about side effects and social support in efforts to cope with side effects.Conclusions
Interventions focusing on skills related to ART side-effects management show promise for improving ART adherence among persons experiencing high levels of perceived ART side effects. 相似文献15.

OBJECTIVE: An examination of the relationship of plasma cobalamin (vitamin B(12)) level to overall psychological distress, specific mood states, and major depressive disorder was conducted in 159 bereaved men (90 HIV-1(+) and 69 HIV-1(-)). METHODS: The relationship of a continuous measure of cobalamin level to psychological distress was examined, while controlling for HIV-1 serostatus, life stressors, social support, and coping styles. RESULTS: Of this sample, 23.9% were either overtly or marginally cobalamin deficient; however, the deficiency rate was not significantly different by HIV-1 serostatus. Cobalamin level was inversely related to self-reported overall distress level and specifically to depression, anxiety, and confusion subscale scores, as well as to clinically rated depressed and anxious mood. Lower plasma cobalamin levels also were associated with the presence of symptoms consistent with major depressive disorder. CONCLUSION: These findings suggest that cobalamin level may be physiologically related to depressed and anxious mood level, as well as to syndromal depression. 相似文献

ABSTRACTObjectives: In a rapidly aging world population, an increasingly large group faces age-related decline in cognitive functioning. Cognitive complaints of older adults are often related to worries and concerns associated with age-related functional decline. Mindfulness-Based Stress Reduction (MBSR) can successfully target stress, worry and ruminative thinking, but the applicability of this method in middle-aged and older adults with memory complaints is unclear.Method: Patients of a university hospital memory clinic (n = 13), aged 45–85 years, with memory complaints but no diagnosis of cognitive disorder, participated in a standard 8-week MBSR program, consisting of weekly group meetings and a one-day silent retreat. After completion, semi-structured qualitative interviews were conducted. Questionnaires (administered before, one week after and five weeks after the intervention) assessed quality of life, psychological distress (stress, anxiety and depressive symptoms), mindfulness, self-compassion, and subjective memory functioning. Neurocognitive functioning was assessed online, before and after the intervention.Results: The qualitative analysis showed positive effects of the training (e.g. increased serenity), many participants worrying less about memory complaints. The self-reported measures were in line with the results of the qualitative analysis.Conclusion: This exploratory mixed-methods study suggests that MBSR is feasible and well received among older individuals with cognitive complaints. 相似文献

OBJECTIVE: After surgery for breast cancer, many women experience anxiety relating to the cancer that can adversely affect quality of life and emotional functioning during the year postsurgery. Symptoms such as intrusive thoughts may be ameliorated during this period with a structured, group-based cognitive behavior intervention. METHOD: A 10-week group cognitive behavior stress management intervention that included anxiety reduction (relaxation training), cognitive restructuring, and coping skills training was tested among 199 women newly treated for stage 0-III breast cancer. They were then followed for 1 year after recruitment. RESULTS: The intervention reduced reports of thought intrusion, interviewer ratings of anxiety, and emotional distress across 1 year significantly more than was seen with the control condition. The beneficial effects were maintained well past the completion of adjuvant therapy. CONCLUSIONS: Structured, group-based cognitive behavior stress management may ameliorate cancer-related anxiety during active medical treatment for breast cancer and for 1 year following treatment. Group-based cognitive behavior stress management is a clinically useful adjunct to offer to women treated for breast cancer. 相似文献

Background: Failure to adhere to medication regimes is a significant problem in clinical and research settings yet reliable, consistent
identification of key psychosocial predictors remains elusive. Studies of mood and personality related to adherence show mixed
results—compliance and objectively measured cognitive function are intuitively related but empirical support is lacking.Purpose: This study is a secondary analysis to examine the relations between adherence with a medication regime for lowering serum
cholesterol and several domains of psychological and cognitive functioning.Methods: Participants in the initial study completed a measure of personality and a battery of neuropsychological measures at baseline;
anxiety and depression were measured at baseline and at 4-week intervals. Medication adherence was tracked with electronic
cap monitors for 24 weeks.Results: Only 23% of the sample was fully adherent to medication regimes at least 80% of the time over the 6-month study period.
Conscientiousness, according to the Five Factor Theory of Personality, and estimated IQ remained robust predictors of adherence
in hierarchical regression analyses. Depression and anxiety, mental flexibility, and visuospatial-constructional ability were
less robust but statistically significant (p < .05) correlates of adherence.Conclusions: Although results of this analysis explain only a portion of the variance in adherence, they demonstrate the importance of
trait psychological and cognitive factors in adherence research.

ObjectiveSleep disturbances are prevalent, persistent, and impairing features of bipolar disorder. However, the near-term and cumulative impact of the severity and variability of sleep disturbances on symptoms and functioning remains unclear. We examined self-reported daily sleep duration and variability in relation to mood symptoms, medication adherence, cognitive functioning, and concurrent daily affect.MethodsForty-one outpatients diagnosed with bipolar disorder were asked to provide daily reports of sleep duration and affect collected via ecological momentary assessment with smartphones over eleven weeks. Measures of depressive and manic symptoms, medication adherence, and cognitive function were collected at baseline and concurrent assessment of affect were collected daily. Analyses examined whether sleep duration or variability were associated with baseline measures and changes in same-day or next-day affect.ResultsGreater sleep duration variability (but not average sleep duration) was associated with greater depressive and manic symptom severity, and lower medication adherence at baseline, and with lower and more variable ratings of positive affect and higher ratings of negative affect. Sleep durations shorter than 7–8 h were associated with lower same-day ratings of positive and higher same-day ratings of negative affect, however this did not extend to next-day affect.ConclusionsGreater cumulative day-to-day sleep duration variability, but not average sleep duration, was related to more severe mood symptoms, lower self-reported medication adherence and higher levels of negative affect. Bouts of short- or long-duration sleep had transient impact on affect. Day-to-day sleep variability may be important to incorporate into clinical assessment of sleep disturbances in bipolar disorder. 相似文献

Understanding stress and coping among individuals with psychogenic nonepileptic seizures (PNES) may have important treatment implications. 40 patients with PNES, 20 with epilepsy (EPIL), and 40 healthy control (HC) participants reported the frequency of various stressful life events (both positive and negative) and appraised the distress these events induced. They also described their habitual coping behaviors. PNES patients reported no more frequent stressful life events than EPIL patients or HC. In addition, the stressors they experienced are not objectively more severe. However, they reported more severe distress due to negative life events, especially in the domains of work, social functioning, legal matters, and health. PNES patients also engaged in less planning and active coping than HC. Neither of these two coping behaviors was associated with distress ratings. The PNES group did not engage in more denial than either group. However, greater denial among PNES patients was associated with greater perceived distress. Coping in PNES is characterized by elevated levels of perceived distress and fewer action strategies than are normally employed to reduce the impact of a stressor. These findings may inform cognitive behavioral therapy of PNES patients. 相似文献
