Perceived control and well-being in Parkinson's disease

Invisible, Uncontrollable, Unpredictable: Illness Experiences in Women with Sjögren Syndrome

Background/Objectives: Sjögren's Syndrome (SS) is a chronic degenerative rheumatic disease. Because of its chronic nature, it significantly affects the quality of life of those who suffer from it. Methods: This qualitative study investigated disease experience among women suffering from SS to understand its impact on their overall well-being. In-depth interviews were conducted with 15 women who suffer from SS. Interviews were analyzed using the Grounded Theory methodology, using open, axial, and selective coding. Results: Three central phenomena of disease experience were identified: invisibility; uncontrollability; and unpredictability. Conclusions: SS disease experience has a strong imprint on emotional well-being and sense of self-control among middle-aged women. Understanding SS impacts on women's lives is important to better understand the disease and contribute to recognizing potential areas of management and social support in relevant windows of opportunity within the health-disease continuum.

The association between the sense of control and depression during the COVID-19 pandemic: a systematic review and meta-analysis

Introduction

High levels of depression and low sense of control have been reported during the COVID-19 pandemic. The removal of typical freedoms through public health restrictions may have played an important role. The aim of this review was to examine data collected during the pandemic and (1) estimate the strength of the association between sense of control and depression, (2) examine whether the different types of control measures affected the strength of the association, and (3) whether this changed as a function of pandemic indicators.

Methods

We conducted a systematic review and meta-analysis of studies published in English between December 2019 and November 2022. A total of 993 articles were identified, of which 20 were included in the review and 16 in the meta-analysis after conducting a quality assessment using the standard NIH tool.

Results

The control-depression association gave a bias-independent pooled effect size of r = .41, and grew stronger over the 130 weeks covered by this review but did not change as a function of local COVID incidence rates. Subgroup analyses showed that external and overall control were more strongly related to depression than internal control.

Discussion

These findings emphasize that external factors are important to the sense of control and the importance of preserving the sense of control in situations where the removal of personal freedoms is necessary, such as public health emergencies.

Psychosocial interventions affecting global perceptions of control in people with Parkinson's disease: a scoping review

PURPOSE

Perceived control is an important construct for the psychological well-being of people affected by chronic conditions, and higher perceived control is associated with better outcomes. Psychosocial interventions have been trialled in these populations to improve both global and specific perceptions of control. However, most interventions involving people with Parkinson's have focused on single-domain forms of control, while those addressing global perceived control are yet to be reviewed. This study aimed to identify and map the types of psychosocial interventions in individuals with Parkinson's which have included forms of global perceived control as an outcome.

MATERIALS AND METHODS

Scoping review based on a search across MEDLINE, PsycINFO, CINAHL, Academic Search Ultimate.

RESULTS

From an initial return of 4388 citations, 12 citations were eventually included. These consisted of 8 quantitative and 4 qualitative studies, and covered 4 overarching categories of psychosocial interventions. Mixed results were found for cognitive, educational, and physical interventions, while a randomised controlled trial on mindfulness-based lifestyle programme showed more preliminary positive evidence.

CONCLUSIONS

Further rigorous research is required on the topic to build on these preliminary findings. In the meantime, clinicians may need to consider programmes which proved effective with populations similar to people with Parkinson's.IMPLICATIONS FOR REHABILITATIONPerceived control is a psychological construct important for people with chronic illnesses, which can be targeted by psychosocial interventions.This article reviewed psychosocial interventions targeting global forms of perceived control in Parkinson's.Mixed results were reported for the cognitive, educational, and physical interventions identified, while a randomised controlled trial on a mindfulness-based lifestyle programme showed more promising evidence.In the meantime, clinicians may need to consider programmes found to be effective with people with similar conditions to Parkinson's.

Barriers and enablers to switching from a solid to a liquid formulation of Parkinson's medication: a theory-based mixed methods investigation

BACKGROUND

Swallowing tablets/capsules can become difficult and dangerous for People with Parkinson's (PwP) who develop oropharyngeal dysphagia. Switching to a liquid delays the need for progressing to last line patches/injections. However, liquids are rarely used therefore a change in prescribing practice is warranted but, as with any change in behaviour, may be met with resistance.

AIM

To characterise PwPs and carers' barriers and enablers (determinants) of switching from solid to liquid Parkinson's medication formulations.

METHOD

Underpinned by the Theoretical Domains Framework, focus groups with PwPs and carers were convened to identify determinants of switching, which were then used to develop a questionnaire distributed across the UK. Determinants were prioritised if ≥ 50% of respondents agreed/strongly agreed that they were important to their decision to switch to a liquid formulation. Percentage precisions were reported as 95% confidence intervals.

RESULTS

From three focus groups and 131 questionnaires responses, PwPs and carers prioritised nine determinants. Three enablers had almost unanimous agreement: liquids' flexibility for incremental dosing (72% ± 8); decline in Parkinson's control (72% ± 8); prescriber's endorsement to switch (70% ± 8). The barriers: perception that tablets/capsules are easier to dose than liquids (72% ± 8); and prescriber's opposition to switching (70% ± 8), attracted similarly high agreement.

CONCLUSION

There is a desire to switch to liquids when Parkinson's progresses and for their use beyond this to offer flexibility in dosing, a previously unrecognised indication for switching. The only notable resistance to switching may be addressed by innovations from the pharmaceutical industry to make liquids easier to measure.

A Systematic Review on Physical Health Education Interventions for People with Parkinson's Disease: Content, Impact, and Implementation Considerations Across the Parkinson's Trajectory

BACKGROUND

Educational interventions promoting the role of physical activity (PA) aim to address knowledge, poor exercise self-efficacy, and low outcome expectations, which are well-researched barriers to PA participation in healthy and in people with chronic conditions. However, little is known about the effectiveness of educational interventions in addressing these barriers in people with Parkinson's (PwP).

OBJECTIVE

To examine the content of education interventions that promote PA behavior in PwP, and to assess their effectiveness on physical and psychosocial outcomes.

METHODS

An electronic search (12/2021) of MEDLINE, EMBASE, CINAHL, PubMed PsycINFO, the Web of Science and the Cochrane Library was conducted from 1990 to 2021. Education interventions, alone or combined with other strategies, promoting PA in PwP were included. Quality was assessed using the Johanna Briggs Institute and National Institute of Health quality assessment tools. A narrative synthesis was performed.

RESULTS

Six studies were identified. Five interventions were comprised of education and exercise sessions. Improvement in physical and psychosocial outcomes were suggested but delineating the exact impact of education was impeded due to lack of assessment.

CONCLUSION

Few interventions exist that provide knowledge, and skills promoting PA participation, and fewer are addressed towards newly diagnosed PwP. There is lack of assessment over the effectiveness of education as a tool to facilitate PA participation in PwP. Lack of assessment poses the risk of potentially disregarding effective interventions or adopting ineffective approaches without the evidence. Education interventions can boost PA engagement by increasing factors such as exercise self-efficacy, but further interventions are required to assess this model of relationship.

Mindfulness-based lifestyle programs for the self-management of Parkinson's disease in Australia

Despite emerging evidence suggesting positive outcomes of mindfulness training for the self-management of other neurodegenerative diseases, limited research has explored its effect on the self-management of Parkinson's disease (PD). We aimed to characterize the experiences of individuals participating in a facilitated, group mindfulness-based lifestyle program for community living adults with Stage 2 PD and explore how the program influenced beliefs about self-management of their disease. Our longitudinal qualitative study was embedded within a randomized controlled trial exploring the impact of a 6-week mindfulness-based lifestyle program on patient-reported function. The study was set in Melbourne, Australia in 2012-2013. We conducted semi-structured interviews with participants before, immediately after, and 6 months following participation in the program. Sixteen participants were interviewed prior to commencing the program. Of these, 12 were interviewed shortly after its conclusion, and 9 interviewed at 6 months. Prior to the program, participants felt a lack of control over their illness. A desire for control and a need for alternative tools for managing the progression of PD motivated many to engage with the program. Following the program, where participants experienced an increase in mindfulness, many became more accepting of disease progression and reported improved social relationships and self-confidence in managing their disease. Mindfulness-based lifestyle programs have the potential for increasing both participants' sense of control over their reactions to disease symptoms as well as social connectedness. Community-based mindfulness training may provide participants with tools for self-managing a number of the consequences of Stage 2 PD.

Cancer, a relational disease exploring the needs of relatives to cancer patients

Purpose: In this qualitative interview study we investigated the experiences of family members to cancer patients. Our objective was to explore and to differentiate their needs from the needs of cancer patients.

Methods: Five focus groups and six individual narrative interviews with 17 family members to cancer patients in Sweden were conducted and compared with 19 cancer patient interviews. Our analysis was inspired by classic grounded theory.

Results: Family members to cancer patients expressed own morbidity connected to high stress levels and difficulties in recognizing own stress due to ongoing comparisons with the cancer patient. Family members were trapped in a momentary terror-like situation where they became their sick relative’s safety net. A percieved inability to improve their loved one’s well being contributed to a feeling of guilt. The longing for it all to end was encumbered with shame since the end included possible death.

Conclusions: By recognizing cancer as a disease striking both body and relationships, family members are given precedence over their own struggles, differentiated from the patient’s experiences. We define differences in needs between cancer patients and family members. Family members to cancer patients may be supported in developing balancing strategies towards less stress, increased safety and moments of contentment.

Improving Functional Status in African Americans With Cancer Pain: A Randomized Clinical Trial

OBJECTIVES

To determine the efficacy of the Power Over Pain-Coaching (POP-C) intervention to improve functional status among African American outpatients with cancer pain.
.

SAMPLE & SETTING

310 African American patients were recruited from an urban comprehensive cancer center. The study took place in the patients' homes.
.

METHODS & VARIABLES

A two-group randomized design with repeated measures was used. Data were analyzed with linear mixed effects regression analysis and structural equation change score models. Variables were pain, pain-related distress, functional status, perceived control over pain, and the following antecedents to control.

RESULTS

Functional status was improved in POP-C participants relative to control group participants (p < 0.05). Distress also was differentially decreased (p < 0.05). Pain intensity ratings decreased significantly in all patients (p < 0.05). The largest intervention effects were observed in the living with pain component. 
.

IMPLICATIONS FOR NURSING

Perceived control over pain was strongly related to functional status and is amenable to interventions using the POP-C intervention components described in this article.

Caregiver Burden in Parkinson Disease: A Critical Review of Recent Literature

Burden is a negative psychological state induced in caregivers by the demands of providing care to a person with an illness or a disability. Managing caregiver burden in Parkinson disease (PD) is significant because informal caregivers make a substantial contribution to the well-being of persons with PD, incurring financial, social, and personal losses. Failure to recognize and manage caregiver burden may lead to burnout and premature institutionalization of the person with PD. We conducted a comprehensive literature review to identify and summarize factors that may amplify burden, including motor and nonmotor symptoms of PD, caregiver psychiatric symptoms, and caregiver coping style. We review instruments designed to sample the construct of burden among caregivers and evaluate interventions that may reduce burden, either by directly targeting caregivers or by treating PD symptoms associated with burden. We aim to provide a concise synopsis of these issues for the clinician or researcher working with this population in order to facilitate recognition of caregiver burden, provide accurate assessment, administer appropriate interventions, and stimulate further research in this area.

Health-related quality of life as a predictor of recurrent falling in Parkinson's disease: 1-year follow-up study

OBJECTIVE

The aim of this study was to assess whether various domains related to health-related quality of life could be predictive of recurrent falls among persons with Parkinson's disease (PD) during a 1-year follow-up study.

METHODS

A total of 120 consecutive persons with PD who had denied falling in past 6 months were recruited at regular check-ups at the Department of Movement Disorders, Neurology Clinic, Clinical Center of Serbia in Belgrade, from 15 August 2011 to 15 December 2012. At baseline, study participants were clinically assessed. Health-related quality of life was evaluated with the generic 36-item Short Form Health Survey. Participants were prospectively followed for 1 year, and occurrence of falls was registered.

RESULTS

The median age of subjects was 60.0 years, with a median disease duration of 4.0 years. Of 120 persons with PD, 42 (35%) experienced falls during the 12-month study period, including 23 (19.2%) who fell repeatedly. After adjustment for gender, age, PD duration, levodopa dosage, Hoehn and Yahr stage, Unified Parkinson's Disease Rating Scale I-IV, Hamilton Depression Rating Scale, and Hamilton Anxiety Rating Scales, we identified the 36-item Short Form Health Survey domains of role physical (P = 0.033) and vitality (P = 0.019) as being associated with recurrent falls of persons with PD within the 1-year follow-up period.

CONCLUSION

Baseline 36-item Short Form Health Survey scores regarding both the physical and mental components of overall health may be related to recurrent falling among persons with PD. These HRQoL domains could be considered as potential markers for persons with PD who are prone to recurrent falls.

Young people with Parkinson's disease: Report of a pilot study to identify the research issues and approaches to data collection

Parkinson's disease (Pd) affects over 120,000 people in the UK. Onset usually begins in people over 50 but in a significant number of people symptoms first develop at a much earlier age without affecting life expectancy. A pilot study to explore quality of life, psychological adjustment and service use for this population initially foundered because of difficulties in contacting a sample of younger people with Pd and motivating them to participate. The pilot study was then extended to determine these people's perceptions of their condition and their needs through content analysis of a magazine circulated by their user group, and a website. Information was also sought from key informants working with young people with Pd. This eventually resulted in contact with the target sample and the collection of valuable data through participation in a conference held by the user group. Reasons for reluctance to become involved in traditional research studies related to denial of having Pd; a desire to conceal it from others, and tiredness associated with Pd, resulting in the need to prioritise activities.

This unorthodox piloting proved invaluable in refining the original study questions and identifying more effective approaches to data collection and sampling. The experience of undertaking the pilot study may be of wider interest because it indicated that despite NHS reforms focusing on the user perspective, some health consumers were not enthusiastic about participating in research or informing government policy. The importance of thorough pilot work to the success of the eventual investigation is also demonstrated.

Predictors of the psychosocial impact of being a carer of people living with Parkinson's disease: a systematic review

INTRODUCTION

Caring for a person with Parkinson's disease (PwP) can have a variety of negative consequences that may challenge their ability to continue their caring role. It is still unknown why some individuals adapt better than others in response to such burdens. This review is the first to synthesize and evaluate the evidence on the predictive factors of psychosocial outcomes in PwP carers.

METHODS

Studies which identified predictors of psychosocial outcomes for unpaid carers were included. PsychINFO, EMBASE, AMED, BNI and CINAHL databases were searched, supplemented by scanning of references lists of included studies and relevant journals from 2008 onwards. Quality was assessed using the NICE methodology checklist for prognostic studies.

RESULTS

Twenty-nine studies were included in the review, providing a low-level of evidence. Carer burden was investigated in 18 studies and mental health and quality of life (QoL) in seven studies each. PwP non-motor symptoms and QoL and carer depression were consistently identified as predictors for at least one psychosocial outcome. Demographics and disease factors were consistently found not to be predictors. Carer involvement and protective factors (e.g. social support, personality) demonstrated promising findings but studies were too few or factors measured inconsistently.

CONCLUSION

Confident conclusions could not be drawn regarding the most important predictors that should be targeted in psychosocial interventions due to methodological weaknesses and lack of theoretical testing across the current literature. Future research should build upon psychological theory to gain a better understanding of the mechanisms that explain how carers adapt to caregiving.

A comparison of caregiver burden in older persons and persons with Parkinson's disease or dementia in sub-Saharan Africa

BACKGROUND

Caregiver burden includes the many physical, mental and socio-economic problems arising from caring for individuals with chronic and disabling diseases. Being a carer in sub-Saharan Africa (SSA), where little is known about chronic neurological conditions, may be extremely demanding. Conversely, multigenerational living may allow sharing of care among many caregivers. We wished to determine the relative burden of caring for two chronic neurodegenerative conditions (Parkinson's disease (PD) and dementia) in rural Tanzania.

METHODS

All surviving patients from a PD prevalence study, newly identified people with PD from a neurological disorders study and all people with dementia from a dementia prevalence study in Hai, rural Tanzania, were invited to participate. The Zarit Burden Interview (ZBI) was used to determine level of caregiver strain (higher score reflects more strain).

RESULTS

Of 25 PD patients ZBI was recorded in 20 (14 male). Five had no identifiable carer as they were largely independent. Three had PD dementia (PDD). Of 75 people with dementia (excluding 3 PDD), 43 (32 female) completed the ZBI. For the other 32, the caregivers felt the care they provided was a normal intergenerational expectation. Median ages were 78.5 and 85 years for PD and dementia, respectively. Median ZBI was 30.5 for PD and 14 for dementia (U = 166.0, z = -3.913, p < 0.001). Disease duration and disease type (PD or dementia) were univariate predictor of ZBI score, although only disease type was predictive by multivariable linear regression.

CONCLUSIONS

Caring for an individual with PD may be more burdensome than caring for an individual with dementia in SSA. People with more advanced PD had higher caregiver burden.

Control perceptions and control appraisal: relation to measures of subjective well-being

OBJECTIVES

To investigate the relationship between control variables and measures of subjective well-being. The primary question asked was "who is happy and well, and why?"

DESIGN

A questionnaire survey and the data was analyzed by examining bivariate relationships between variables of interest.

PARTICIPANTS

Two hundred and fifty six (256) adults within the age range of 18-88 years. They were mainly undergraduate psychology students from South-Eastern part of the United States and solicited in a manner consistent with the Institutional Review Board of the Florida State University. Elderly persons from community groups (e.g. churches, social organizations) were solicited through their appropriate leaders and announcements.

RESULTS

The mean age of the participants was 32 years. Findings indicated significant relationship between control measures, indices of wellbeing, and individual's satisfaction with the quality of their lives. Significant correlations were between 0.177 and 0.469 at the 0.01 level (2-tailed). Having control in the areas of social support, self-acceptance, positive relationships, purpose in life, and personal growth were judged important.

CONCLUSION

The findings of this study suggest that essential 'ingredients' for psychological and subjective well-being include enjoyment of good health, some financial stability, meaningful ties with others, a sense of purpose and direction in life, ability to manage complex life demands, a healthy self-acceptance and commitment to personal development. Implications for clinical utility and future research are discussed.

An interpretative phenomenological analysis of delusions in people with Parkinson's disease

PURPOSE

The aim of this qualitative study was to explore what delusional experiences mean for people with Parkinson's disease (PD) and to examine how psychosocial factors contribute to the development and maintenance of delusional beliefs.

METHOD

Eight participants were interviewed, and interpretative phenomenological analysis was used to identity themes within their accounts. Participants were either recruited from a hospital-based outpatient movement disorder clinic or from a PD support group in the north-west of England.

RESULTS

Four themes emerged from the analysis: (1) 'I got very frightened': The emotional experience associated with delusions; (2) 'Why the hell's that happening?': Sense of uncertainty and of losing control; (3) 'I feel like I'm disintegrating': Loss of identity and sense of self; (4) 'I've just tried to make the best of things': Acceptance and adjustment to experience of delusions. These interconnected themes in participants' accounts of delusional beliefs were reflected in their descriptions of living with, and adjusting to, PD.

CONCLUSIONS

The results of this study add to the evidence base indicating the urgent examination of psychological alternatives to conventional, medication-based approaches to alleviating the distress caused by delusions in people with PD.

Social support for physical activity and perceptions of control in early Parkinson's disease

PURPOSE

The purpose of this article is to investigate how social support influences physical activity participation, as perceived by men and women in the early stages of Parkinson's disease (PD). It will also address how this perceived support interacts with perceptions of control to influence this participation.

METHOD

Three women and four men with early PD completed a background questionnaire and participated in individual semi-structured interviews. The World Health Organisation's International Classification of Functioning, Disability and Health (ICF) model was used as a framework to develop questions related to the environmental factors examined. Phenomenology was employed in the analysis of interview transcripts.

RESULTS

Three main types of support (instrumental, emotional, informational) were provided to participants, and each of these had a positive influence on physical activity participation. In addition to this support, participants reported personally participating in exercise as a means to help control the progression of PD.

CONCLUSIONS

This is believed to be the first study looking at factors influencing physical activity participation in PD. Issues related to support for exercise from physicians and organisational issues of support groups for PD are discussed. Directions for future research are provided, which should aid in the identification of strategies to increase physical activity levels in those with PD.

Effects of optimism/pessimism and locus of control on disability and quality of life in Parkinson's disease

PURPOSE

To assess optimism/pessimism and locus of control in a sample of Parkinson's disease patients and to evaluate their impact on disability and health-related quality of life.

METHODS

99 patients with Parkinson's disease completed the Life Orientation Test, Multidimensional Health Locus of Control, Older Americans Resource and Services Activities of Daily Living Subscale, and Short Form-12 Health Status Survey. Disease stage and severity measures were completed by movement disorder specialists. Correlations and multivariate regressions compared optimism/pessimism and locus of control with disability and health-related quality of life.

RESULTS

Higher optimism and less pessimism were associated with better mental health quality of life. Greater internal locus of control was associated with less disability. These results remained significant when controlling for disease severity.

CONCLUSIONS

Low optimism or high pessimism is associated with reduced quality of life in Parkinson's disease. Patients with less internal locus of control have greater disability. Interventions that promote personal control and positive attitudes may assist in reducing disability and improving quality of life in Parkinson's disease.

Self-Management, Perceived Control, and Subjective Quality of Life in Multiple Sclerosis

Self-management has been shown to increase perceived control over both illness and nonillness aspects of life among people with chronic conditions but has not received significant research attention among persons with multiple sclerosis (MS). Based on relationships proposed in the illness intrusiveness and disability centrality models, this study explored the relationships between subjective and objective measures of MS impact, self-management, perceived control, and subjective quality of life (SQOL). A sample of 157 adults with MS participated in this research. The results suggest that self-management is strongly associated with perceived control and that both perceived control and self-management mediate the relationship between MS impact and SQOL. The rehabilitation counseling implications of these findings are discussed.

Factors that affect functional status in patients with cancer-related pain

Cancer-related pain in outpatient adult populations remains high and has a direct effect on functional status. Factors that affect functional status have been explored separately, but the inter-relatedness of those factors has not been examined. Using a cross-sectional design, the purpose of this study was to examine the relationships between pain level, beliefs about pain, symptom distress, perceived control over pain, and functional status in 304 ambulatory cancer patients who experienced cancer-related pain within the past 2 weeks. Participants completed standardized questionnaires during regularly scheduled clinic visits. Patient's pain level was positively related to increased distress and decreased perceived control over pain and functional status. Structural equation modeling indicated that symptom distress mediated the relation between pain level and functional status. Perceived control over pain had a direct effect on symptom distress and mediated the effect of beliefs about pain and pain level on symptom distress. Patients' perceived control over pain may be an important component in pain management. The direct and mediating effects of perceived control and symptom distress suggest areas of further research. Interventions to increase knowledge and decrease barriers to pain control have the potential for increasing perceived control over pain.

Perceptions of control over pain by patients with cancer and their caregivers

The purpose of this qualitative inquiry was to broaden the context for understanding perceived control as a concept related to the cancer pain response in the homecare setting. Ten patient/caregiver dyads participated in semistructured interviews focused on questions pertaining to the patients' perceived control over their own pain as well as the caregivers' control over the patients' pain. Line-by-line analysis was used to code, categorize, and analyze the data. Six themes emerged among patients: feeling robbed of the simplest of tasks and pleasures, the pain is hungry, feeling desperate, the pain is winning, fatigue/sleep disturbances, and perceived control is soothing. For the caregivers, four main themes emerged: monitoring the suffering, feeling like an outsider, inability to control the interventions, and importance of resources. Overall, patients and their caregivers were eager to discuss how their perceived lack of control over pain affected their daily lives. The results suggest perceived control over pain is an important aspect of the pain response in the homecare setting. Nurses should evaluate perceived control over pain in patients with cancer and their caregivers and implement and test potential methods for increasing perception of control over pain.

Theoretical perspectives of perceived control in older adults: a selective review of the literature

AIM

This paper is a report of a theoretically based review of literature exploring the concept of perceived control in relation to older adults.

BACKGROUND

Perceived control is a cognitive attribute that is a precursor to function, a mediator between social support and psychological wellbeing, and instrumental for effective disease self-management. It has been defined from several theoretical perspectives with either a global or a specific focus.

METHODS

A review of literature was conducted. Articles were abstracted into a table in order to compare the purpose, theoretical framework, definition of perceived control, scope of application of perceived control, research questions, subjects, methods, instruments and findings across studies. The articles were sorted by theoretical framework for analyses among and between theoretical frameworks.

RESULTS

Twenty papers published between 1995 and 2005, listed in CINAHL or Medline, with the words 'perceived control' in the title, and which included older adults as at least half of the sample and used one of five predominant theoretical frameworks were included in a review of the literature. In this review, perceived control is defined within the theories of social learning, self-efficacy, planned behaviour, the lifespan theory of control, and from a person-environment framework. There is little consensus among researchers as to the definition of perceived control.

CONCLUSION

Lack of consensus on the theoretical underpinnings and variability in definition of perceived control exist. The mechanisms through which perceived control develops and is exercised are also in dispute. Nevertheless, there is general agreement that high perceived control is important for wellbeing in older adults.

Freezing of gait affects quality of life of peoples with Parkinson's disease beyond its relationships with mobility and gait

The aim of this study was to examine the association between freezing of gait (FOG) and quality of life (QoL) in patients with Parkinson's disease (PD). PD patients (n = 118) completed the PDQ-39 (QoL) and FOG-Q questionnaires. Disease severity was assessed by the Hoehn and Yahr (H&Y) staging and the Unified Parkinson's Disease Rating Scale (UPDRS). The relations between those parameters were assessed using regression models. 66 men and 52 women (mean age 65.8 +/- 10.2 years, UPDRS total score 48.4 +/- 17.1, disease duration 8.5 +/- 5.8 years, H&Y stage 2.7 +/- 0.8) participated. FOG severity had a significant effect on QoL (P < 0.0015), accounting for disease severity assessed by UPDRS. Specifically, FOG severity was correlated with all the dimensions of the PDQ-39 except for stigma and social support, as follows: with mobility, bodily discomfort, activity of daily living (ADL) (P < 0.005 in all), with emotional, communication, and cognition (P < 0.05 in all). FOG severity (FOG-Q) was also found to affect a modified PDQ total score, without the mobility aspect (P = 0.0081). FOG should be viewed as a highly important symptom with regard to QoL of PD patients beyond its effect on gait and mobility. On the basis of the present results, special attention should be given to FOG in the treatment of patients with PD.

A randomized controlled trial to reduce delay in older adults seeking help for symptoms of acute myocardial infarction

Older adults with symptoms of acute myocardial infarction (AMI) have longer pre-treatment delay times than their younger counterparts. A 2-group, randomized controlled sample consisted of 115 adults, 65 years of age or older with a self-reported history of coronary artery disease. A pre-test was given to all participants followed by a structured education and counseling intervention to those in the experimental group. Data were re-collected at 3 months. There was a statistically significant increase in knowledge, beliefs, and perceived control without an increase in anxiety in the intervention group. There was no significant difference in attitudes. Older adults at risk for AMI should be targeted for individualized education and counseling in clinics, physician offices, and community centers.

The experience of long-term diagnosis with human immunodeficiency virus: a stimulus to clinical eupraxia and person-centred medicine

The biopsychosocial challenges of living with human immunodeficiency virus (HIV) have changed over time and they dictate the need for relevant medical services. The meaning of an HIV diagnosis has moved from a terminal to a manageable condition with the development of antiretrovirals, bringing profound changes to the experience of living with HIV and the meaning and use of diagnostic labels. Six biological stage-related categories in the literature of psychological medicine of HIV are critiqued. Long-term HIV highlights the inadequacy of physician-centred, acute-care medicine in chronic illness and its exclusion of preventive, psychological and rehabilitative modalities. 'Eupraxia' is presented as a conceptual framework for chronic care medicine, referring to best practice, wellbeing, best interests, and (public) welfare, through facilitated but collaborative approaches. A public-centred service model is proposed, using idiographic assessment and treatment by clinicians as patient delegates (proxies), monitoring joined-up care, providing group-based biopsychosocial treatment, facilitating autonomous and self-managing behaviour by the public, removing professional and practice hierarchies, and implementing real-time clinical and managerial accountability with public ownership and involvement. This model is superior in its health-and cost-effectiveness but can only work within a nationalized system that focuses equally on standardized outcomes and evidential and personalized health outcomes.

Group debriefing for people with chronic diseases during the SARS pandemic: Strength-Focused and Meaning-Oriented Approach for Resilience and Transformation (SMART)

This study presented preliminary results on the efficacy of a novel group debriefing model called Strength-Focused and Meaning-Oriented Approach for Resilience and Transformation (SMART). The SMART debriefing (1) aimed at boosting resilience and catalyzing transformation among persons undergoing stressful events, (2) adopted a growth-oriented and holistic approach of health promotion, and (3) employed methods drawn from various indigenous sources (e.g. Asian philosophies and Traditional Chinese Medicine). Participants (N=51) were people with chronic diseases recruited about 1 month (August 2003) after the Severe Acute Respiratory Syndrome (SARS) outbreak was eventually under control, after causing widespread panic in Hong Kong. After the one-day group debriefing, participants showed significant decrease in depression level, as measured by Brief Symptom Inventory (Derogatis & Melisaratos, 1983, Psychological Medicine, 13(3), 595-605) and changes in cognitive appraisal towards SARS. Such changes were sustained in a 1-month follow-up. Clinical implications and directions for further study were discussed.

Pain management skills of regional nurses caring for older people with Dementia: A needs analysis

An exploratory survey of the pain management education needs of 197 nurses working with older people with dementia was undertaken in a regional area of Queensland, Australia. The analysis indicated that nurses in this setting might not have the knowledge base to manage pain effectively; and that respondents have essentially negative perceptions of the availability and appropriateness of current pain management education programs. Consistent with non-metropolitan nurses generally, respondents expressed a preference for pain management education that had a significant face-to-face component allied with ongoing mentorship and support on completion of the program. The obstacles to attending such programs were also typical of the problems facing regional and rural nurses throughout Australia. These were identified as: inability to pay for courses; lack of information on what is available; distance to travel to education; and a perceived lack of employer support due to an inability to replace those staff attending education. Positive aspects include the degree to which participants were responsive and interested in dementia pain management and their access to, and acceptance of, non-medical pain therapies. The findings suggest a definite need for a dementia pain management program for aged care nurses, specifically tailored to their needs and to the constraints of the regional practice setting.

Quality of life of caregivers

This article is a descriptive analysis of various features of the quality of life (QoL) of the caregivers in different pathological conditions. Definitions of the concept of QoL, caregiver goals and burdens, caregiver stress and coping with factors that could contribute to or impact the QoL in caregivers are discussed both through a review of literature and an analysis of empirical evidences. The QoL in caregivers of patients with Parkinson's disease is also discussed. An original Scale of QoL of Caregivers is described and compared with other existing measures. The concepts of patient-caregiver dyad in research and in interventions is stressed.

Being a Parkinson's patient: immobile and unpredictably whimsical literature and existential analysis

What is characteristic of being a Parkinson's patient? This article intends to answer this question by means of an analysis of novels about people with Parkinson's disease, personal accounts, and scientific publications. The texts were analyzed from an existential-phenomenological perspective, using an adapted version of the existential analysis. Being a Parkinson's patient is apparently characterized by an existential paradox: life appears simultaneously immobile and unpredictably whimsical. This may manifest itself in the person's corporeality, in his being-in-time and in-space, in his relating to things and events, his life-world, and in his being-together-with-others as an individual. Finally, some specific characteristics of being a Parkinson's patient are described that may be relevant for purposes of adequate care, as is to be specified by further research.

An education programme for individuals with Parkinson's disease

An education programme for individuals with Parkinson's disease. People with Parkinson's disease (PD) have to face a lot of ongoing sickness - depending on limitations in daily life and society. Ability for optimal living demands knowledge about the sickness, medications, side-effects and knowledge about the best way to go on living with PD. In this study, 43 persons with PD participated in an outpatient programme based on the structure of connection model. The programme consisted of two weekly 2-h sessions for 5 weeks. Each session consisted of 1 h of dialogue and 1 h of physical performance. The two teachers in the programme were registered nurse and registered physiotherapist. The programme was evaluated with focus on participants' psychosocial situation, mobility and activity in daily living. Participating in the programme gave these individuals an improved psychosocial situation and improved mobility pattern. However, these improvements were not transferred to habitual daily life, which suggests that task-oriented training provides the best solution.

Contributions of disease severity and perceptions of primary and secondary control to the prediction of psychosocial adjustment to Parkinson's disease

Seventy-four people with Parkinson's disease (PD) completed questionnaires and were interviewed to determine the degree to which the severity of PD and perceptions of primary and secondary control over PD predicted psychosocial adjustment. Significant unique contributions to PD-related participation restrictions were made by disease severity (positive relationship) and perceived internal secondary control (negative relationship). Also, participation restrictions had a significant direct effect, and disease severity and perceived internal secondary control significant indirect effects, on both depressive symptomatology and life satisfaction. Results are consistent with theories that suggest the importance of enhancing internal secondary control processes in situations in which actual control over objective circumstances is limited, such as with chronic and progressive diseases like PD.

African Americans with cancer: the relationships among self-esteem, locus of control, and health perception

The purpose of this study was to describe and examine the relationships among self-esteem, locus of control, and perceived health status in African Americans with cancer and to identify predictors of perceived health status. A convenience sample of 95 oncology outpatients at two large medical facilities completed the Tennessee Self-Concept Scale, the Multidimensional Health Locus of Control Scale, and the Cantril Ladder, a measurement of perceived health. In an audiotaped interview two open-ended questions were used to clarify participants' Cantril Ladder scores. A significant positive relationship was discovered between self-esteem and powerful others health locus of control (p <.05). Participants tended to view God as the Powerful Other capable of influencing their health and well-being. Self-esteem and an internal health locus of control were found to account for 23% of the perceived variance in health status. In addition, interview data indicated that participants with normal to high levels of self-esteem and an internal health locus of control perceived their state of health and well-being positively.

The Influence of Caregiver Burden on Patients’ Management of Parkinson's Disease: Implications for Rehabilitation Nursing

In this study, we examined how the perceived burdens of caregivers influence how people with Parkinson's disease (PD) manage their condition. Burden has previously been defined as the extent to which caregivers perceive that their health, social life, and financial status are being adversely affected because of their care giving. We hypothesized that when caregivers perceive that their burden is increasing, the level of management by PD patients of their disease decreases. A purposive sample of 41 couples in which one spouse or partner had PD was obtained through physician referrals, PD educational programs, and support groups in six Midwestern states. Twenty-eight of the PD patients were men and 13 were women; their spouses or partners included 28 women and 13 men. How patients managed the disease was measured with the Management of Parkinson's Disease Instrument, developed by the first author. The Zarit Perceived Burden Inventory was used to measure the caregivers' perceived burdens. A significant path (p < .02) was noted between the spouse or partner's perceived burden of care and the patient's management of the disease (beta = -.067). A path coefficient of beta = -365 was obtained. The role of the rehabilitation nurse in the relationship of caregiver and care recipient is that of counselor, educator, and supporter.

Older Swedish women's experiences of living with symptoms related to Parkinson's disease

BACKGROUND

Approximately 1% of the population over 65 years of age is afflicted with Parkinson's disease (PD). The number of patients with the disease will most probably increase in the future because of the increased longevity of the population. There is no curative therapy for the disease.

AIM

To explore women's experiences of living with symptoms related to PD, and to analyse how the symptoms influence their quality of life.

METHODS

A phenomenological-hermeneutic method, inspired by the philosophy of Ricoeur was used. The study focuses on eight women between 63 and 80 years of age who have been diagnosed with PD for 5-15 years. The women all lived at home, were moderately to severely disabled and cognitively intact.

FINDINGS

In the analysis, four themes emerged: (1) wish for a stable body image; (2) wish to keep traditional female competence; (3) need to feel accepted for the person she is; and (4) perceived stigmatization. All themes showed that trying to adapt to unpredictable fluctuations in physical and psychosocial competence has a great impact on the females' lives. It became clear that fluctuations in competence and not knowing when to expect impaired mobility are connected with frustration and social withdrawal.

CONCLUSION

The experience of PD from eight disabled female patients has revealed that the disease affects quality of life not only for the person who has it, but also for her family. Thus, it is equally urgent that patients, relatives, nurses and caregivers gain better knowledge and more understanding of PD, so as to ease the impact of the disease on the patient's daily life.

Impact of in-home defibrillators on postmyocardial infarction patients and their significant others: an interview study

OBJECTIVE

To investigate the impact of automated external defibrillator (AED) placement in the homes of postmyocardial infarction (MI) patients and their significant others.

DESIGN

This qualitative study used a semistructured interview to examine a nonrandomized convenience sample recruited from a larger study of home AEDs.

SETTING AND PARTICIPANTS

Patients (and their significant others) were recruited from an ongoing study of AED use in the home. Seventeen interviews with 15 patients (14 men, 1 woman) and 16 significant others (1 man, 15 women) aged 39 to 80 years were performed in patients' homes.

METHODS

Verbatim transcripts of audiotaped interviews were reviewed, and responses were categorized. Other data were obtained from hospital chart abstraction.

RESULTS

The majority of subjects noted only positive effects of the presence of home AEDs (eg, giving them feelings of security and control). There was no evidence that AED presence in the home caused excessive anxiety or stress either in patients or their significant others, nor were they perceived to cause relationship stress. On average, patients and their significant others estimated a 38% and 43% (respectively) risk of cardiac arrest and a 92% and 87% likelihood of a successful resuscitation with the use of the AED. Subjects' perceived risk of cardiac arrest were subjectively related to their estimate of current health status, size of infarction, and symptoms during their MI. Subjects also related their estimates of risk to their likelihood of traveling with their AED and whether they would consider purchasing one. Significant others had high confidence in their ability to properly use the AED.

CONCLUSIONS

AEDs were valued highly by subjects and enhanced their perceived control over their heart disease. This was especially true for subjects who believed that their risk of cardiac arrest was high. The possible effects of providing education regarding expert estimates of the likelihood of cardiac arrest and of a successful resuscitation at the time of AED placement are discussed.

The evolving concept of health in nursing research: 1988-1998

This article concerns the evolution of the concept of health, as reported in selected nursing journals, over the last 10 years. It builds on an analysis reported by Reynolds [Reynolds CL. The measurement of health in nursing research. Adv Nurs Sci 1988;10(4):23-31.] who initially investigated the concept of health and the means by which it was measured during the period 1977-1987. Using the same journals as Reynolds, the methodology of systematic review is used to analyse the way in which health is defined, the frequency with which it is investigated and the means by which it is measured, and these data are compared with Reynolds findings. The results indicate that; three times as many studies have been conducted in the last 10 years, a more holistic concept of health has emerged, and the instruments used are becoming more sophisticated. These findings are discussed and the implications for patient education and health care professionals considered.

Spousal perspective of Parkinson's disease in middle life

An interpretive study in America explored the experience of living with a partner who has Parkinson's disease (PD) in middle life. Challenges experienced by eight spouses and their ways of coping with these challenges were examined. The convenience sample of five wives and three husbands were 44-58 years and had been married 4 months to 30 years. Spouses described the most significant challenges as watching their partner struggle and be frustrated; and renegotiating their lives. The coping strategies most frequently used were maintaining their own life, encouraging their partner to stay active and involved, and seeing the challenges they experienced as secondary. The context of living with a partner with Parkinson's disease is illuminated and strategies that spouses find most effective in coping with their partners illness are identified.

The quality of life in Parkinson's disease

The objective of this study was to examine the quality of life in patients with Parkinson's disease (PD) in a community-based sample (n = 228 patients) using a Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) as a measure. Associations to the variables age, age at onset, duration, clinical stage (Hoehn and Yahr), depression (Zung), and dementia (MMSE) were studied. Women scored significantly lower on five of the eight dimensions of SF-36. Depression, as measured in this study, was more common among parkinsonian women than men. Depression was the factor that was associated most significantly with the experienced quality of life, according to SF-36. With physical functioning, only the clinical stage had a more significant association than depression. To improve the quality of life in patients with PD, it is necessary to make every effort to recognize and relieve the depression of patients with PD.

Perceived control, coping efficacy, and avoidance coping as mediators between spouses' unsupportive behaviors and cancer patients' psychological distress

This study examined whether avoidance, coping efficacy, and perceived control mediate the effects of spouses' unsupportive behaviors on patient psychological distress among 191 married individuals enrolled in cancer treatment. Results of the structural equation analyses suggested that avoidance and coping efficacy mediated the relationship between spouses' unsupportive behaviors and patient psychological distress. Perceived control of emotional aspects of the illness, including emotional responses and relationships with family and friends, and perceived control of the medical course of the cancer did not mediate the relationship between spouses' unsupportive behaviors and patient psychological distress. These findings suggest 2 mechanisms to explain why unsupportive responses from spouses may be associated with psychological distress among cancer patients.
