Videoconference-delivered group Cognitive Behavioral Stress Management for ME/CFS patients who present with severe PEM: A randomized controlled trial.

Background: In Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), post-exertional malaise (PEM) is associated with greater distress and symptoms. Cognitive Behavioral Stress Management (CBSM) has demonstrated beneficial effects for ME/CFS and may mitigate stress-related triggers of PEM. We tested a virtual CBSM intervention to increase access, and we report on its effects on stress and symptoms in ME/CFS patients with severe PEM. Methods: Data were from a randomized controlled trial (NCT01650636) comparing 10-week videoconference-delivered group CBSM (V-CBSM, n=75) to a 10-week Health Information active control (V-HI, n=75) in Fukuda criteria ME/CFS patients (71 classified as highPEM, 79 lowPEM). Linear regression explored PEM-by-Treatment interactions on overall symptom frequency and intensity, perceived stress, and fatigue-specific interference and intensity, at 5-month follow-up. Logistic regression tested V-CBSM effects on 5-month PEM status. Analyses controlled for age, gender, race/ethnicity, mode of symptom onset, and time since diagnosis. Results: The sample was middle-aged (47.96±10.89 years), mostly women (87%) and non-Hispanic White (65%), with no group differences on these variables or baseline PEM. For highPEM patients, V-CBSM (versus V-HI) demonstrated medium to large effects on follow-up symptom frequency, symptom intensity, fatigue interference, and fatigue intensity (p's < .05) and trending to significant reductions in perceived stress (p =.07). Differences were not evident for lowPEM patients. Treatment predicted follow-up PEM status at a trend (p = .058), with patients receiving V-CBSM demonstrating half the risk of highPEM classification versus V-HI. Conclusions: V-CBSM demonstrates benefits for ME/CFS patients presenting with severe PEM and may reduce the expression of PEM over time.

Familism, family cohesion, and health-related quality of life in Hispanic prostate cancer survivors.

BACKGROUND: Familism, the cultural value that emphasizes feelings of loyalty and dedication to one's family, has been related to both positive and negative outcomes in Hispanic cancer survivors. One potential source of observed inconsistencies may be limited attention to the family environment, as familism may be protective in a cohesive family whereas it can exacerbate distress in a conflictive family. PURPOSE: The current study explored the associations of familism with general and disease-specific health-related quality of life (HRQoL) in Hispanic men who completed prostate cancer (PC) treatment, and whether family cohesion may help explain these relationships. METHODS: Hispanic men treated for localized PC (e.g., radiation, surgery) were enrolled in a randomized controlled stress management trial and assessed prior to randomization. Familism (familial obligation) was assessed using Sabogal's Familism Scale and family cohesion was measured using the Family Environment Scale (ranging from high to low). The sexual, urinary incontinence, and urinary obstructive/irritative domains of the Expanded Prostate Cancer Index Composite - Short Form measured disease-specific HRQoL. The physical, emotional, and functional well-being subscales of the Functional Assessment of Cancer Therapy - General captured general HRQoL. Hierarchical linear regression and the SPSS PROCESS macro were used to conduct moderation analyses, while controlling for relevant covariates. RESULTS: Participants were 202 older men on average 65.7 years of age (SD = 8.0) who had been diagnosed with PC an average of 22 months prior to enrollment. Familism was not directly associated with general and disease-specific HRQoL. Moderation analyses revealed that greater familism was related to poorer urinary functioning in the incontinence (p = .03) and irritative/obstructive domains (p = .01), and lower emotional well-being (p = .02), particularly when family cohesion was low. CONCLUSIONS: These findings underscore the importance of considering contextual factors, such as family cohesion, in understanding the influence of familism on general and disease-specific HRQoL among Hispanic PC patients. The combined influence of familism and family cohesion predicts clinically meaningful differences in urinary functioning and emotional well-being during the posttreatment phase. Culturally sensitive psychosocial interventions to boost family cohesion and leverage the positive impact of familistic attitudes are needed to enhance HRQoL outcomes in this population.

Predictors of initial engagement with an asynchronous cognitive behavioral stress management website among older women with nonmetastatic breast cancer.

PURPOSE: Digital interventions, like websites, offer greater access to psychosocial treatments; however, engagement is often suboptimal. Initial use may be a target to "hook" participants. Few studies examine engagement with cognitive behavioral stress management (CBSM). We tested predictors of engagement in the first week of using a CBSM website among women with breast cancer (BC). METHODS: Older women (≥ 50 years) with nonmetastatic BC enrolled in an on-going trial (8/2016-4/2022, #NCT03955991) and were randomized to receive 10 synchronous, virtual CBSM group sessions immediately (n = 41) or after a 6-month waitlist (n = 34). All received simultaneous access to an asynchronous website, where supplemental videos and resources were released weekly. Engagement was tracked via breadth (features used) and depth (clicks within content). Multilevel modeling tested predictors of engagement (i.e., time, condition, age, daily stress, depression, race, ethnicity, disease stage). RESULTS: Breadth decreased over the first week of CBSM (b = -0.93, p < .01), and women with more advanced stage disease engaged with more breadth (b = 0.52, p < .01) and depth (b = 14.06, p < .01) than women with earlier stage disease. Non-Hispanic (b = -0.59, p = .03) and White (b = -0.97, p < .01) women engaged with more features. Cancer stage and intervention timing interacted. Women with more advanced cancer stage who received CBSM later engaged with the most depth (b = -11.73, p = .04). All other characteristics did not predict engagement. CONCLUSIONS: Disease stage, race, ethnicity, and intervention timing predicted engagement with a CBSM website in older BC patients. IMPLICATIONS FOR CANCER SURVIVORS: Delivering CBSM later in cancer treatment may mitigate competing demands. Fostering greater engagement in racial/ethnic minorities is needed.

Post-exertional malaise is associated with greater symptom burden and psychological distress in patients diagnosed with Chronic Fatigue Syndrome.

OBJECTIVE: Post-exertional malaise (PEM) is often considered a cardinal symptom of Chronic Fatigue Syndrome (CFS). There is no gold standard diagnostic method for CFS, however, and the Centers for Disease Control (CDC) Fukuda case definition does not require PEM. Research has identified differences in symptom burden between patients according to PEM, but whether it is associated with psychological distress has not been investigated. METHODS: The CDC CFS Inventory, Fatigue Symptom Inventory, Profile of Mood States, Center for Epidemiologic Studies Depression Scale, Perceived Stress Scale, and subscales of the Sickness Impact Profile were administered to 261 patients diagnosed with the Fukuda criteria. PEM status (loPEM/hiPEM) was determined via self-reported post-exertional fatigue severity. Analyses of covariance (ANCOVA), controlling for age and gender, assessed cross-sectional group differences, and cross-sectional linear regressions using the continuous PEM severity predictor paralleled these analyses. RESULTS: hiPEM patients reported greater symptom intensity, frequency, and interference than loPEM counterparts (p's < .001). hiPEM patients also reported greater social disruption, depressive symptoms, and mood disturbance (p's ≤ .011). Groups did not differ in recent negative life experiences, perceived stress, or demographic variables. The results of regression analyses mirrored those of ANCOVAs. CONCLUSION: This study replicates the association between PEM and symptom burden and additionally associates PEM with psychological distress; psychological distress could, however, be a consequence of symptom burden. Differences between hiPEM and loPEM CFS patients highlight the heterogeneity of diagnoses resulting from the Fukuda criteria. It is also possible that PEM identifies particularly distressed patients for whom psychological intervention would be most beneficial.

Relationship satisfaction, communication self-efficacy, and chronic fatigue syndrome-related fatigue.

RATIONALE: Relationship dissatisfaction has been linked with worse health outcomes in many patient populations, though the mechanism(s) underlying this effect are unclear. Among patients with chronic fatigue syndrome (CFS) and their partners, there is evidence for a bi-directional association between poorer relationship satisfaction and the severity of CFS-related fatigue. OBJECTIVE: Here, we hypothesized that relationship dissatisfaction negatively impacts fatigue severity through greater depression and less patient satisfaction about communication about symptoms to partners. METHOD: Baseline data were drawn from diagnosed CFS patients (N = 150) participating in a trial testing the efficacy of a stress management intervention. Data derived from fatigue severity (Fatigue Symptom Index, FSI), depression (Center for Epidemiologic Survey-Depression, CES-D), relationship quality (Dyadic Adjustment Scale, DAS) and communication satisfaction (Patient Symptom Disclosure Satisfaction, PSDS) questionnaires were used for bootstrapped indirect effect analyses using parallel mediation structural equation modeling in Mplus (v8). Age and BMI were entered as covariates. RESULTS: Greater relationship satisfaction predicted greater communication satisfaction (p < 0.01) and lower CES-D scores (p < 0.01), which in turn were each significantly related to greater fatigue severity (p < 0.05). Tests of the indirect paths indicated that relationship satisfaction had a significant effect on fatigue severity through both constructs, but primarily via depression. There was no direct association between relationship satisfaction and fatigue severity after the intermediate variables (depression, communication satisfaction) were included in the model. CONCLUSION: Results highlight the importance of considering depression and communication-related factors when examining the effects of relationship satisfaction on CFS symptoms such as fatigue. Further mechanism-based, longitudinal research might identify relationship-related mediating variables that can be targeted therapeutically.

Implementation of a Psychosocial Intervention Program for Working Caregivers.

The overall aim of this pilot study was to examine the feasibility and acceptability of a multicomponent, psychosocial intervention specifically designed to meet the unique needs of caregivers who are balancing caregiving duties with work responsibilities. Seventy-one family caregivers employed at a private, nonprofit institution in South Florida were randomized to either the Caregiver Workstation condition (n = 35) or a control condition (n = 36). Sixty-two caregivers completed the 5-month follow-up. Our results indicate that an intervention tailored to the time demands of a working caregiver is feasible, acceptable to caregivers, and has the potential to have positive long-term effects. Currently, there are limited data available regarding the benefits of employer programs for caregivers or the type of programs caregivers find most useful. This pilot study is the first step in developing a working caregiver intervention program that can be implemented on a broad-scale basis.

Study design and protocol for a culturally adapted cognitive behavioral stress and self-management intervention for localized prostate cancer: The Encuentros de Salud study.

Almost 2.8 million men in the U.S. are living with prostate cancer (PC), accounting for 40% of all male cancer survivors. Men diagnosed with prostate cancer may experience chronic and debilitating treatment side effects, including sexual and urinary dysfunction, pain and fatigue. Side effects can be stressful and can also lead to poor psychosocial functioning. Prior trials reveal that group-based cognitive behavioral stress and self-management (CBSM) is effective in reducing stress and mitigating some of these symptoms, yet little is known about the effects of culturally-translated CBSM among Spanish-speaking men with PC. This manuscript describes the rationale and study design of a multi-site, randomized controlled trial to determine whether participation in a culturally adapted cognitive behavioral stress management (C-CBSM) intervention leads to significantly greater reductions in symptom burden and improvements in health-related quality of life relative to participation in a non-culturally adapted cognitive behavioral stress management (CBSM) intervention. Participants (N = 260) will be Spanish-speaking Hispanic/Latino men randomized to the standard, non-culturally adapted CBSM intervention (e.g., cognitive behavioral strategies, stress management, and health maintenance) or the culturally adapted C-CBSM intervention (e.g., content adapted to be compatible with Hispanic/Latino cultural patterns and belief systems, meanings, values and social context) for 10 weeks. Primary outcomes (i.e., disease-specific symptom burden and health-related quality of life) will be assessed across time. We hypothesize that a culturally adapted C-CBSM intervention will be more efficacious in reducing symptom burden and improving health-related quality of life among Hispanic/Latino men when compared to a non-culturally adapted CBSM intervention.

Community REACH: An Implementation of an Evidence-Based Caregiver Program.

Background and Objectives: Family caregivers (CGs) are critical to the provision of long-term services and support for older adults. Numerous intervention programs to alleviate CG distress have been developed and evaluated yet few have been implemented in community settings. This paper describes and presents outcomes from Community REACH, a community implementation of the evidence-based Resources for Enhancing Alzheimer's Caregiver Health (REACH) II program. Research Design and Methods: Community REACH involved a partnership between REACH II investigators and United HomeCare Services (UHCS), a nonprofit home health organization that provides home health, personal care, companion, and respite services. The intervention program, an adapted version of an evidence-based program, was a 6-month multicomponent psychosocial intervention, which involved six individual face-to-face and six individual telephone sessions, and telephone support groups. One hundred and forty-six CGs who were primarily female (76%) and Latino, and providing care for an individual with Alzheimer's disease (AD) were enrolled. Program effectiveness was assessed by examining changes in perceived social support, burden, and depression, and CG self-efficacy. Results: At 6 months, CGs reported significant decreases in depression, burden, being and bothered by the care recipient's memory problems. There was also a significant decline in the number of CGs at risk for clinical depression. These improvements were maintained at 12 months and there was an increase in feelings of social support. Discussion and Implications: The findings indicate that evidence-based CG programs can be successfully implemented in community settings and benefit CGs of AD patients. A continued partnership between the program developers and community partners is key to implementation success.

Depression, evening salivary cortisol and inflammation in chronic fatigue syndrome: A psychoneuroendocrinological structural regression model.

INTRODUCTION: Chronic Fatigue Syndrome (CFS) is a poorly understood illness that is characterized by diverse somatic symptoms, hypothalamic pituitary adrenal (HPA) axis dysfunction and heightened inflammatory indicators. These symptoms are often exacerbated and accompanied by psychological distress states and depression. Since depression is known to be associated with HPA axis dysfunction and greater inflammation, a psychoneuroendocrinological (PNE) model of inflammation was examined in persons diagnosed with CFS in order to uncover underlying biopsychosocial mechanisms in this poorly understood chronic illness. METHODS: Baseline data were drawn from two randomized controlled trials testing the efficacy of different forms of psychosocial intervention, and included psychological questionnaires, di-urnal salivary cortisol, and blood samples. Data were analyzed with structural equation modeling (SEM). RESULTS: The sample (N=265) was mostly middle-aged (Mage=49.36±10.9, range=20-73years), Caucasian (67.7%), female (81.7%), highly educated (85.5% completed some college, college, or graduate program), and depressed (CES-D M=23.87±12.02, range 2-57). The SEM supporting a psychoneuroendocrinological model of immune dysregulation in CFS fit the data χ2 (12)=17.725, p=0.1243, RMSEA=0.043, CFI=0.935, SRMR=0.036. Depression was directly related to evening salivary cortisol and inflammation, such that higher evening cortisol predicted greater depressive symptoms (ß=0.215, p<0.01) and higher pro-inflammatory cytokines (interleukin-2 [IL-2], IL-6, and tumor necrosis factor-alpha [TNF-α] levels (ß=0.185, p<0.05), when controlling for covariates. DISCUSSION: Results highlight the role of depression, cortisol and inflammation in possible biological mechanisms involved in the pathophysiology of CFS. Time-lagged, longitudinal analyses are needed to fully explore these relationships.

Poor sleep quality is associated with greater circulating pro-inflammatory cytokines and severity and frequency of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) symptoms in women.

OBJECTIVE: Poor sleep quality has been linked to inflammatory processes and worse disease outcomes in the context of many chronic illnesses, but less is known in conditions such as chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). This study examines the relationships between sleep quality, pro-inflammatory cytokines, and CFS/ME symptoms. METHODS: Sixty women diagnosed with CFS/ME were assessed using the Pittsburgh Sleep Quality Index (PSQI), Fatigue Symptom Inventory (FSI) and Center for Disease Control and Prevention (CDC)-based CFS/ME symptom questionnaires. Circulating plasma pro-inflammatory cytokine levels were measured by ELISA. Multiple regression analyses examined associations between sleep, cytokines and symptoms, controlling for age, education, and body mass index. RESULTS: Poor sleep quality (PSQI global score) was associated with greater pro-inflammatory cytokine levels: interleukin-1ß (IL-1ß) (ß=0.258, p=0.043), IL-6 (ß=0.281, p=0.033), and tumor necrosis factor-alpha (TNF-α) (ß=0.263, p=0.044). Worse sleep quality related to greater fatigue severity (ß=0.395, p=0.003) and fatigue-related interference with daily activities (ß=0.464, p<0.001), and more severe and frequent CDC-defined core CFS/ME symptoms (ß=0.499, p<0.001, and ß=0.556, p<0.001, respectively). CONCLUSIONS: Results underscore the importance of managing sleep-related difficulties in this patient population. Further research is needed to identify the etiology of sleep disruptions in CFS/ME and mechanistic factors linking sleep quality to symptom severity and inflammatory processes.

Telephone-administered versus live group cognitive behavioral stress management for adults with CFS.

OBJECTIVE: Chronic fatigue syndrome (CFS) symptoms have been shown to be exacerbated by stress and ameliorated by group-based psychosocial interventions such as cognitive behavioral stress management (CBSM). Still, patients may have difficulty attending face-to-face groups. This study compared the effects of a telephone-delivered (T-CBSM) vs a live (L-CBSM) group on perceived stress and symptomology in adults with CFS. METHODS: Intervention data from 100 patients with CFS (mean age 50years; 90% female) participating in T-CBSM (N=56) or L-CBSM (N=44) in previously conducted randomized clinical trials were obtained. Perceived Stress Scale (PSS) and the Centers for Disease Control and Prevention symptom checklist scores were compared with repeated measures analyses of variance in adjusted and unadjusted analyses. RESULTS: Participants across groups showed no differences in most demographic and illness variables at study entry and had similar session attendance. Both conditions showed significant reductions in PSS scores, with L-CBSM showing a large effect (partial ε2=0.16) and T-CBSM a medium effect (partial ε2=0.095). For CFS symptom frequency and severity scores, L-CBSM reported large effect size improvements (partial ε2=0.19-0.23), while T-CBSM showed no significant changes over time. CONCLUSIONS: Two different formats for delivering group-based CBSM-live and telephone-showed reductions in perceived stress among patients with CFS. However, only the live format was associated with physical symptom improvements, with specific effects on post-exertional malaise, chills, fever, and restful sleep. The added value of the live group format is discussed, along with implications for future technology-facilitated group interventions in this population.

Effect of incretin therapies compared to pioglitazone and gliclazide in non-alcoholic fatty liver disease in diabetic patients not controlled on metformin alone: An observational, pilot study. / Efecto de las terapias incretínicas comparadas con pioglitazona y gliclazida en la esteatosis hepática no alcohólica de los pacientes diabéticos no controlados solo con metformina: estudio observacional piloto.

AIM: To compare the effect of different hypoglycemic drugs on laboratory and ultrasonographic markers of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes not controlled on metformin alone. METHODS: Prospective study of diabetic patients treated with metformin in combination with gliclazide, pioglitazone, sitagliptin, exenatide, or liraglutide. NAFLD was assessed by abdominal ultrasound and NAFLD fibrosis score was calculated at baseline and 6 months. RESULTS: Fifty-eight patients completed 6 months of follow-up: 15 received gliclazide, 13 pioglitazone, 15 sitagliptin, 7 exenatide, and 8 liraglutide. NAFLD affected 57.8% of patients at baseline, and its ultrasonographic course varied depending on changes in weight (P=.009) and waist circumference (P=.012). The proportions of patients who experienced ultrasonographic improvement in the different treatment groups were: 33.3% with gliclazide, 37.5% with pioglitazone, 45.5% with sitagliptin, 80% with exenatide, and 33% with liraglutide (P=.28). CONCLUSIONS: Qualitative ultrasonographic NAFLD improvement in diabetic patients treated with metformin in combination with other hypoglycemic drugs is associated to change over time in weight and waist circumference. Long-term clinical trials are needed to assess whether incretin therapies result in better liver outcomes than other hypoglycemic therapies.

Perceived Fatigue Interference and Depressed Mood: Comparison of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis Patients with Fatigued Breast Cancer Survivors.

OBJECTIVE: Persistent fatigue and depressive symptoms are both highly prevalent among patients with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) as well as breast cancer survivors. This study aimed to assess and directly compare perceptions of fatigue as highly interfering in one's daily functioning in both patient populations to better understand their relationships with depressed mood. METHODS: Participants were 95 female CFS/ME patients and 67 females who were approximately 5 years post-treatment for stage 0-III breast cancer presenting with clinically elevated fatigue severity. Self-report measures were obtained on participants' fatigue-related interference in daily functioning and fatigue severity as well as depressed mood. Hierarchical regression was used to test effects controlling for relevant demographic, psychosocial, and medical covariates. RESULTS: CFS/ME patients endorsed greater depressed mood and fatigue interference than did fatigued breast cancer survivors, p's<.001. These factors were significantly positively correlated among CFS/ME patients (ß=.36, p<.001), but not the fatigued breast cancer survivors (ß=.18, p=.19). CONCLUSIONS: CFS/ME patients reported elevated fatigue symptoms and depression relative to fatigued breast cancer survivors. In the former group, greater depressed mood was highly and significantly associated with greater fatigue-related inference in daily activities. Potential targets for cognitive behavioral interventions are discussed.

Stress management skills, cortisol awakening response, and post-exertional malaise in Chronic Fatigue Syndrome.

Chronic Fatigue Syndrome (CFS) is characterized in part by debilitating fatigue typically exacerbated by cognitive and/or physical exertion, referred to as post-exertional malaise (PEM). In a variety of populations, the cortisol awakening response (CAR) has stood out as a marker of endocrine dysregulation relevant to the experience of fatigue, and may therefore be particularly relevant in CFS. This is the first study to examine PEM and the CAR in a sample of individuals with CFS. The CAR has also been established as a stress-sensitive measure of HPA axis functioning. It follows that better management of stress could modulate the CAR, and in turn PEM. In this cross-sectional study, we hypothesized that greater Perceived Stress Management Skills (PSMS) would relate to lower reports of PEM, via the impact of PSMS on the CAR. A total of 117 adults (72% female) with a CFS diagnosis completed self-report measures of PSMS and PEM symptomatology and a two-day protocol of saliva collection. Cortisol values from awakening and 30 min post-awakening were used to compute the CAR. Regression analyses revealed that greater PSMS related to greater CAR and greater CAR related to less PEM severity. Bootstrapped analyses revealed an indirect effect of PSMS on PEM via the CAR, such that greater PSMS related to less PEM, via a greater CAR. Future research should examine these trends longitudinally and whether interventions directed at improving stress management skills are accompanied by improved cortisol regulation and less PEM in individuals with CFS.

Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Symptom Severity: Stress Management Skills are Related to Lower Illness Burden.

BACKGROUND: The onset of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) typically involves reductions in activities of daily living and social interactions (jointly referred to as "illness burden"). Emotional distress has been linked to increased reported symptoms, and stress management skills have been related to lower fatigue severity in CFS patients. Symptom severity and illness burden are highly correlated. The ability to manage stress may attenuate this relationship, allowing individuals to feel less burdened by the illness independent of the severity of their symptoms. PURPOSE: This study aimed to evaluate if perceived stress management skills affect illness burden via emotional distress, independent of ME/CFS symptom severity. METHODS: A total of 117 adults with ME/CFS completed measures of perceived stress management skills, emotional distress, ME/CFS symptom severity and illness burden. RESULTS: Regression analyses revealed that greater perceived stress management skills related to less social and fatigue-related illness burden, via lower emotional distress. This relationship existed independent of the association of symptom severity on illness burden, and was stronger among those not currently employed. CONCLUSIONS: Ability to manage stress is associated with a lower illness burden for individuals with ME/CFS. Future studies should evaluate the efficacy of psychosocial interventions in lowering illness burden by targeting stress management skills.

A videophone psychosocial intervention for dementia caregivers.

BACKGROUND/OBJECTIVES: Available services and intervention programs for dementia caregivers are often underutilized because of issues such as cost, logistics, lack of knowledge about available services, or insufficient support from others. Information technologies offer the potential of removing these barriers and facilitating the ability of caregivers to access needed support. This project evaluated the feasibility and efficacy of technology-based psychosocial intervention among minority family caregivers of dementia patients. DESIGN: A feasibility and efficacy trial. SETTING: Participants' homes in the Greater Miami Community. PARTICIPANTS: One hundred ten (56 Hispanic American and 54 African American) caregivers of patients with dementia. INTERVENTION: A technology-based multi-component psychosocial intervention was delivered in-home and via videophone technology over 5 months. The intervention was modeled after the REACH II intervention and targeted known areas of caregiver risk. MEASUREMENT: Standardized measures of depression, caregiver burden, social support, and the caregivers' perception of the caregiver's experience were administered at baseline and 5 months post-randomization. RESULTS: Overall, caregivers who received the intervention reported a decrease in burden, an increase in perceived social support and positive perceptions of the caregiving experience. No effect was observed for depression. Most participants indicated that the intervention improved their caregiving skills and found the technology to be easy to use. CONCLUSIONS: A technology-based format was feasible for delivering a multi-component intervention to minority family dementia caregivers. The intervention improved caregiver outcomes for both Hispanic and African American caregivers. The results suggest that technology may help eliminate disparities in access to caregiver intervention programs.

Stress management skills, neuroimmune processes and fatigue levels in persons with chronic fatigue syndrome.

OBJECTIVES: Stressors and emotional distress responses impact chronic fatigue syndrome (CFS) symptoms, including fatigue. Having better stress management skills might mitigate fatigue by decreasing emotional distress. Because CFS patients comprise a heterogeneous population, we hypothesized that the role of stress management skills in decreasing fatigue may be most pronounced in the subgroup manifesting the greatest neuroimmune dysfunction. METHODS: In total, 117 individuals with CFS provided blood and saliva samples, and self-report measures of emotional distress, perceived stress management skills (PSMS), and fatigue. Plasma interleukin-1-beta (IL-1ß, IL-2, IL-6, IL-10, and tumor necrosis factor-alpha (TNF-α), and diurnal salivary cortisol were analyzed. We examined relations among PSMS, emotional distress, and fatigue in CFS patients who did and did not evidence neuroimmune abnormalities. RESULTS: Having greater PSMS related to less fatigue (p=.019) and emotional distress (p<.001), greater diurnal cortisol slope (p=.023) and lower IL-2 levels (p=.043). PSMS and emotional distress related to fatigue levels most strongly in CFS patients in the top tercile of IL-6, and emotional distress mediated the relationship between PSMS and fatigue most strongly in patients with the greatest circulating levels of IL-6 and a greater inflammatory (IL-6):anti-inflammatory (IL-10) cytokine ratio. DISCUSSION: CFS patients having greater PSMS show less emotional distress and fatigue, and the influence of stress management skills on distress and fatigue appear greatest among patients who have elevated IL-6 levels. These findings support the need for research examining the impact of stress management interventions in subgroups of CFS patients showing neuroimmune dysfunction.

Improving the quality of life of caregivers of persons with spinal cord injury: a randomized controlled trial.

OBJECTIVE: To assess the efficacy of two psychosocial interventions for caregivers of older persons with spinal cord injury (SCI). DESIGN: A multisite, three-group, randomized controlled trial comparing two active intervention conditions with each other and to an information-only control group. One hundred seventy-three caregiver and care-recipient dyads were randomly assigned to one of three conditions: a caregiver-only treatment condition in which caregivers received a multicomponent intervention based on their risk profile; a dual-target condition in which the caregiver intervention was complemented by a treatment targeting the care recipient, designed to address both caregiver and care recipient risk factors; and an information-only control condition in which the caregiver received standard printed information about caregiving, SCI, and aging. OUTCOME MEASURES: A multivariate outcome comprised of six indicators linked to the goals of the interventions was the primary outcome of the study. The multivariate outcome included measures of depressive symptoms, burden, social support and integration, self-care problems, and physical health symptoms. RESULTS: At 12 months, caregivers in the dual-target condition had improved quality of life as measured by our multivariate outcome when compared to the control condition. Using the dyad as the unit of analysis, the dual-target condition was superior to both the control condition and the caregiver-only condition in our multivariate outcomes analysis. Dyads enrolled in the dual-target condition had significantly fewer health symptoms than control condition and caregiver-only condition participants and were less depressed when compared to participants in the caregiver-only condition. In follow-up analyses we found that a higher proportion of caregivers in the dual-target condition had clinically significant improvements in depression, burden, and health symptoms when compared with the caregiver-only condition. CONCLUSION: Caregivers are in need of and can benefit from interventions that help them manage the medical and functional limitations of the care recipient. Intervention strategies that target both the caregiver and care recipient are particularly promising strategies for improving the quality of life of caregivers.

An evaluation of performance by older persons on a simulated telecommuting task.

Telecommuting work represents a strategy for managing the growing number of older people in the workforce. This study involved a simulated customer service telecommuting task that used e-mail to answer customer queries about media-related products and company policies. Participants included 27 "younger" older adults (50-65 years) and 25 "older" older adults (66-80 years). The participants performed the task for two 2-hr sessions a day over 4 consecutive days. Although both age groups showed significant improvement across sessions on many of the performance criteria, in general the improvements were more marked for the older age-group participants. However, the participants from both age groups had difficulty meeting some of the task performance requirements. These results are discussed in terms of training strategies for older workers.

A cost-benefit analysis methodology for assessing product adoption by older user populations.

A methodology for assessing perceptions of a product through cost-benefit analysis is demonstrated in an experimental study involving use of one of two products for supporting interaction with telephone voice menu systems. The method emphasizes ratings of constructs related to costs and benefits considered relevant to decisions regarding product adoption, and the use of the analytic hierarchy process technique to derive subjective importance weights associated with those constructs. Twenty-five younger subjects (18-39 years of age) and 27 older subjects (60-82 years of age) interacted with simulated telephone voice menu systems supported by either a screen phone or a graphical device. Although analysis of the benefit-cost ratios revealed that benefits were perceived as more important than costs, the analysis of the constituent item ratings and importance weights provided potentially more useful information for predicting product adoption.
