Independent and mediated contributions of personality, coping, social support, and depressive symptoms to physical functioning outcome among patients in cardiac rehabilitation

Changes in coping strategies, social support, optimism and health-related quality of life following traumatic brain injury: A longitudinal study

PRIMARY OBJECTIVE

To study longitudinal changes in psychological coping strategies, social support, life orientation and health-related quality of life in the late period after traumatic brain injury (TBI).

SUBJECTS

Thirty-one patients with TBI who were first investigated on average 2.3 years after injury and were prospectively followed on average 5.7 years later.

METHODS

Estonian versions of the COPE-D Test, the Brief Social Support Questionnaire, the Life Orientation Test and the RAND-36 questionnaire.

RESULTS

During the late follow-up period health-related quality of life and resuming work did not improve significantly. Persons with TBI reported an increase in seeking social/emotional support (p<0.05), frequent use of avoidance-oriented styles and reduced use of task-oriented styles. This was accompanied by low social support and low satisfaction with support, both of which were associated with health-related quality of life and resuming work after TBI. Although the patients had become more optimistic (p<0.05), this did not correlate with their health status and social well-being.

CONCLUSIONS

This prospective study revealed maladaptive changes in the profile of coping strategies and an increase in optimism. As social support, satisfaction with support and health-related quality of life did not improve, then rehabilitation, social and psychological support are continuously needed.

Obesity and health-related quality of life: does social support moderate existing associations?

OBJECTIVES

Obesity has been shown to be negatively related to physical health-related quality of life (HQOL) much more strongly than mental HQOL. This is remarkable given findings on obesity-related social stigmata and associations with depression. Considering obesity as a stressor, this study tests for a moderating role of social support for obesity/HQOL associations among women and men.

DESIGN

Data come from N=2,732 participants aged 35-74 years in a 2004-2005 general population survey in the Augsburg region, Germany.

METHODS

Body weight and height were assessed by anthropometric measurements (classified by body mass index using WHO standards), social support by the Social Support Questionnaire 14-item Short-Form (F-SozU-K14) and HQOL by the 12-item Short-Form Health Survey (SF-12). In multiple regression and general linear models, age, education, family status, health insurance, and place of residence were adjusted for.

RESULTS

Among both genders, obesity was associated with reduced physical but not mental HQOL. Among men reporting strong social support, physical HQOL was impaired neither in the moderately nor the severely obese group (compared with normal weight), while it was given less social support. Among women, poor physical HQOL was associated with obesity regardless of social support.

CONCLUSIONS

In this adult population sample, no association was found for obesity with mental HQOL. In contrast, a negative association with physical HQOL exists for all subgroups except men with strong social support, indicating that social support buffers obesity-related impairments in physical HQOL in men but not in women. This suggests that obese women and men with strong social support represent distinct populations, with possible implications for obesity care.

Socioeconomic differences in psychosocial factors contributing to coronary heart disease: a review

Psychosocial factors have been shown to play an important role in the aetiology of coronary heart disease (CHD). A strong association between CHD and socioeconomic status (lower-level education, poor financial situation) has also been well established. Socioeconomic differences may thus also have an effect on psychosocial risk factors associated with CHD, and socioeconomic disadvantage may negatively affect the later prognosis and quality of life of cardiac patients. The aim of this study was to review the available evidence on socioeconomic differences in psychosocial factors which specifically contribute to CHD. A computer-aided search of the Medline and PsycINFO databases resulted in 301 articles in English published between 1994 and 2007. A comprehensive screening process identified 12 empirical studies which described the socioeconomic differences in CHD risk factors. A review of these studies showed that socioeconomic status (educational grade, occupation or income) was adversely associated with psychosocial factors linked to CHD. This association was evident in the case of hostility and depression. Available studies also showed a similar trend with respect to social support, perception of health and lack of optimism. Less consistent were the results related to anger and perceived stress levels. Socioeconomic disadvantage seems to be an important element influencing the psychosocial factors related to CHD, thus, a more comprehensive clarification of associations between these factors might be useful. More studies are needed, focused not only on well-known risk factors such as depression and hostility, but also on some lesser known psychosocial factors such as Type D and vital exhaustion and their role in CHD.

Emotional support and affect: associations with health behaviors and active coping efforts in men living with HIV

The present study represents a cross-sectional examination of the relationship between affect, social support and illness adjustment in men diagnosed with HIV/AIDS. Positive and negative affect were examined as separate mediators of the relationship between emotional support received from a primary support provider and illness adjustment in 105 men living with HIV. Results suggested that depressive symptoms emerged as a mediator between emotional support and engaging in healthy lifestyle behaviors (assessed by summary index). In contrast, positive affect emerged as the primary mediator between emotional support and greater amounts of active coping. Overall, findings suggested that emotional support from close others was indirectly associated with health behaviors and coping through recipients' affective states, and that these positive and negative affective states had differential relationships with multiple aspects of illness adjustment in men living with HIV.

Masculine role variables and outcomes among men with spinal cord injury

PURPOSE

Few studies have considered the impact of masculine role variables on outcome and adjustment to SCI among men. The present study examined the relations among SCI, views of masculinity, psychological adjustment, and rehabilitation outcomes among men with SCI.

METHOD

The sample included 20 men with SCI receiving inpatient rehabilitation, with a mean age of 45 years. Data included demographic variables as well as Conformity to Masculine Norms Inventory (CMNI), Gender Role Conflict Scale (GRCS), Functional Independence Measure (FIM), and Satisfaction with Life Scale ratings, and change in marital status.

RESULTS

The findings revealed that satisfaction with life was positively related to scores on the CMNI Violence scale, FIM change from admission to discharge was positively related to the CMNI Emotional Control scale and negatively related to the CMNI Dominance scale. Change in marital status was inversely related to the CMNI Emotional Control and Primacy of Work scales and the GRCS Restricted Emotionality and Power, Success, and Competition scales.

CONCLUSIONS

The findings show that certain aspects of the traditional masculine role (i.e., ability to modulate strong emotions) may be adaptive in the rehabilitation process, whereas other aspects (i.e., a dominant interpersonal style) may present a barrier to effective rehabilitation.

Normal personality characteristics in schizophrenia: a review of the literature involving the FFM

Schizophrenia is generally viewed as a disruption of normal functioning because of an underlying core illness. A number of theorists have speculated that this core illness may unilaterally disrupt normal personality functioning. However, recent data suggests that the relationship may be more complex and reciprocal than previously conceptualized. Furthermore, basic personality characteristics appear to be associated with numerous clinical phenomena. This article reviews the empirical literature pertaining to normal personality characteristics [structured around the five-factor model (FFM) of personality] in individuals with schizophrenia. Evidence suggests that certain personality characteristics may be uniquely related to the etiology of psychosis, as well as symptom severity, occupational functioning, cigarette smoking, substance use and violent behavior, social isolation, and suicidality in patients with schizophrenia. The implications of these findings and suggestions for future research are discussed.

Differential effects of faith-based coping on physical and mental fatigue in middle-aged and older cardiac patients

PURPOSE

This analysis investigated the effect of faith-based coping used by cardiac patients undergoing surgery on physical and mental fatigue, symptoms which have significant prognostic implications for mortality. Particularly, we explored whether this faith effect is independent or explained by positive mediators.

METHODS

Two weeks preoperatively, 481 patients (male, 58%; mean age = 62 years) were recruited for three sequential interviews. Among them, 426 completed the second interview, and 335 completed the post-operative follow-up. Cross-clamp and bypass time were obtained from patients' charts. Plasma interlukin-6 (IL-6) was used as a correlate of age-associated diseases and frailty.

RESULTS

Hierarchical multiple regression analyses showed that pre-operative positive religious coping styles and optimism contributed to reduced physical fatigue, controlling for post-operatively confirmed prayer coping and such covariates as severe injury. Depression and lower-back problems contributed to mental fatigue. No potential mediators explained these effects.

CONCLUSION

Faith-based coping and optimism are independent predictors of physical fatigue.

Pessimism and physical functioning in older women: influence of self-efficacy

The purpose of the present study was to examine the nature of the relationships among dispositional optimism/pessimism, self-efficacy, and physical function in a cross-sectional sample of older women (N = 249, M age = 69 years). Initial bivariate analyses indicated that both pessimism and self-efficacy, but not optimism, were significantly correlated with objectively measured physical function. Subsequent analyses using covariance modeling with the full-information maximum likelihood estimator indicated that pessimism was no longer correlated with function when controlling for self-efficacy. That is, consistent with a social cognitive perspective, controlling for self-efficacy attenuated the relationship between pessimism and function. Our findings provide support for using a social cognitive perspective to understanding dispositional and modifiable influences on declines in function associated with aging.

Quality of life and pain in Chinese lung cancer patients: Is optimism a moderator or mediator?

OBJECTIVE

To clarify if optimism exerts a primarily moderating or mediating influence on the pain-QoL association in Chinese lung cancer patients.

METHODS

About 334 Chinese lung cancer patients were interviewed at baseline during the first outpatient visit (Baseline), at 4 months after Baseline (FU1), and at 8 months after Baseline (FU2). Respondents completed the Chinese version of the FACT-G version-3 scale (FACT-G (Ch)). Optimism and pain were assessed using two 11-point self-rated items. Linear mixed effects (LME) models tested the moderating and mediating effects of optimism on QoL.

RESULTS

Optimism, pain, and QoL were most strongly correlated at FU1. LME models failed to show any moderating effect by optimism on the pain-QoL association (standardized beta = -0.049, 95% CI -0.097 to 0.001). After adjustment for age, cancer stage, and disease recurrence, a modest mediating effect was observed for optimism on the pain-QoL association over the duration of the study (standardized beta = 0.047; Sobel test z = -4.317, p < 0.001).

CONCLUSIONS

Optimism qualifies as a mediator between pain and QoL suggesting that pessimistic lung cancer patients are likely to experience greater QoL decrements in response to pain in the early post-diagnostic period. Effective pain control may be enhanced by inclusion of interventions that facilitate optimistic perspectives in patients. This study lends further support to the view that lung cancer patients' psychological needs are important in both pain control and QoL.

Mental and physical symptoms associated with lower social support for patients with hepatitis C

AIM: To systematically examine the impact of the hepatitis C virus (HCV) diagnosis on patients’ level of social support in a large-scale study.

METHODS: Patients evaluated and treated for HCV in a tertiary referral center were enrolled in a cross-sectional study. Demographic data, functional and emotional status as measured by the Hospital Anxiety and Depression Scale (HAD) and the Sickness Impact Profile (SIP), severity of liver disease, mode of acquisition, and physical and psychiatric comorbidities were collected from patients or abstracted from the medical record. All participants completed a semi-structured interview, addressing questions of social support.

RESULTS: A total of 342 patients (mean age 45.2 years; 37% women) were enrolled. Ninety-two (27%) patients described lower levels of support by family and friends. Nearly half of the participants (45%) noted the loss of at least one relationship due to the disease. Fears related to transmitting the disease (25%) were common and often associated with ignorance or even discrimination by others (19%). Nearly one fifth of the patients did not share information about their disease with others to avoid being stigmatized. Lower levels of social support were significantly associated with living alone, being unemployed, being excluded from antiviral therapy, having psychiatric comorbidities, contracting HCV through intravenous drug use, having high levels of anxiety and depression as measured by the HAD and negative mood state as measured by the SIP. Patients reporting lower levels of social support also noted more physical symptoms as measured by the SIP.

CONCLUSION: Patients with hepatitis C often face significant social problems, ranging from social isolation to familial stress. The most common concerns reflect a limited insight of patients and their relatives and friends about the disease, the risk factors for its spread, and about potential consequences. Our data suggest that educational interventions targeting support persons and the stressors identified in our findings may lessen or alleviate the social strains patients with hepatitis C experience.

Optimism, distress, health-related quality of life, and change in cancer antigen 125 among patients with ovarian cancer undergoing chemotherapy

OBJECTIVE

This study investigated whether situational and dispositional optimism were protective against dimensions of distress and aspects of health-related quality of life (HQoL) in patients with ovarian cancer undergoing chemotherapy. This study also evaluated whether optimism predicted a decrease in cancer antigen (CA) 125 levels during treatment.

METHODS

Ninety women with epithelial ovarian cancer were assessed at the start and end of chemotherapy. Optimism, distress, and HQoL were measured by self-report; CA 125 levels were gathered from patients' medical charts.

RESULTS

Both measures of optimism were inversely associated with baseline anxiety, perceived stress, and depression. In addition, situational optimism was positively associated with baseline social and physical well-being, and dispositional optimism was positively associated with baseline social and functional well-being. However, neither measure of optimism predicted domains of distress or HQoL at the follow-up assessment after controlling for baseline levels. Dispositional optimism predicted CA 125 at the end of treatment after controlling for baseline levels. However, neither situational nor dispositional optimism predicted CA 125 falling to normal levels (< or =35 U/mL).

CONCLUSION

Consistent with prior research, optimism was inversely associated with distress and positively associated with HQoL in patients with ovarian cancer undergoing chemotherapy. Higher levels of dispositional optimism at the start of chemotherapy were associated with a greater decline in patients' CA 125 during treatment.

Psychosocial and Cultural Influences on Cardiovascular Health and Quality of Life Among Hispanic Cardiac Patients in South Florida

This study examined whether psychosocial and cultural factors were related to four dimensions of cardiac-related quality of life (global, physical, emotional, and social functioning) in 120 Hispanic coronary heart disease (CHD) outpatients in south Florida. Survey data were collected on sociodemographic (age, gender, socioeconomic status), psychosocial (depression, social support), and cultural factors (acculturation, familism, fatalism), and quality of life. Medical data on CHD severity (New York Heart Association class, time since diagnosis) were obtained from patients' clinic records. Hierarchical regression analyses revealed that women and patients with more severe CHD had poorer quality of life than men or patients with less severe CHD. Psychosocial and cultural factors were associated with poorer quality of life after controlling for sociodemographic and medical variables: Depression was associated with all four quality of life dimensions (p < .001); and fatalism (p < .05) was associated with lower social functioning in women. These findings identify Hispanic subgroups with poor cardiac-related quality of life that can benefit from special outreach.

Predictors of positive psychosocial functioning of older adults in residential care facilities

This research examined the contributions of active and passive coping for health problems, and meaning-based coping, to positive psychosocial functioning in a sample of 100 individuals in residential care with a mean age of 83.11 years old. Study participants resided in skilled care, intermediate care, or assisted living facilities. Based on interview data collected on site in participants' residential settings, hierarchical multiple regression analyses revealed that active and passive coping and meaning-based coping had separate influences on measures of positive psychosocial functioning. Active coping was correlated with higher positive affect, whereas passive coping was associated with higher negative affect and self-acceptance. Positive reappraisal, a meaning-based coping strategy, was uniquely associated with higher positive affect, positive social relations, and self-acceptance. Positive religious coping was not independently associated with positive psychosocial functioning indices, whereas negative religious coping was related to higher negative affect. Health functioning did not contribute to positive psychosocial functioning in this sample. The results confirm the separate importance of health-related and meaning-based coping strategies in explaining positive psychosocial functioning in older adults living in residential care settings.

Prevention and management of cardiovascular disease and erectile dysfunction: toward a common patient-centered, care model

Erectile dysfunction (ED) is highly prevalent in men with cardiovascular disease (CVD), yet it is frequently underrecognized and underdiagnosed in clinical practice. Even among clinicians who acknowledge the relevance of addressing sexual issues in their patients, there is a general lack of awareness of the optimal approach for sexual problem identification and management. Additionally, cardiac rehabilitation programs typically neglect the role of sexual function. The trajectory of CVD and ED may necessitate continuous adjustment by both patients and their partners as they adapt to the chronicity of heart disease and the changing reality of their sexual lives. Health professionals typically approach management of these disorders from a disease-centered perspective, which often fails to incorporate the patient's needs and perspectives. In turn, patients frequently complain of a lack of sensitivity or awareness on the part of their physicians. From a patient-centered perspective, greater emphasis is placed on life satisfaction and quality of life as primary outcomes of treatment. Finally, a patient-centered framework is relevant for both treatment and prevention of cardiac risk in men with ED, in addition to ED management in patients with or without overt CVD.
