Illness beliefs and psychological outcome in people with Parkinson's disease

Social isolation, loneliness and mental health sequelae of the Covid-19 pandemic in Parkinson's disease

People living with Parkinson Disease (PwP) have been at risk for the negative effects of loneliness even before the Coronavirus Disease 2019 (Covid-19) pandemic. Despite some similarities with previous outbreaks, the Covid-19 pandemic is significantly more wide-spread, long-lasting, and deadly, which likely means demonstrably more negative mental health issues. Although PwP are not any more likely to contract Covid-19 than those without, the indirect negative sequelae of isolation, loneliness, mental health issues, and worsening motor and non-motor features remains to be fully realized. Loneliness is not an isolated problem; the preliminary evidence indicates that loneliness associated with the Covid-19 restrictions has dramatically increased in nearly all countries around the world.

Prognosis in functional and recognised pathophysiological neurological disorders - a shared basis

OBJECTIVE

To compare self-reported outcomes, clinical trajectory and utility of baseline questionnaire responses in predicting prognosis in functional and recognised pathophysiological neurological disorders.

METHODS

Baseline data on 2581 patients included health-related quality of life, psychological and physical symptoms, illness perceptions, consultation satisfaction and demographics. The prospective cohort included neurology outpatients classified with a functional (reporting symptoms 'not at all' or 'somewhat explained' by 'organic disease'; n = 716) or recognised pathophysiological disorder ('largely' or 'completely explained'; n = 1865). Logistic regression and deep neural network models were used to predict self-reported global clinical improvement (CGI) at 12-months.

RESULTS

Patients with functional and recognised pathophysiological disorders reported near identical outcomes at 12-months with 67% and 66% respectively reporting unchanged or worse CGI. In multivariable modelling 'negative expectation of recovery' and 'disagreement with psychological attribution' predicted same or worse outcome in both groups. Receipt of disability-related state benefit predicted same or worse CGI outcome in the functional disorder group only (OR = 2.28 (95%-CI: 1.36-3.84) in a group-stratified model) and was not related to a measure of economic deprivation. Deep neural network models trained on all 92 baseline features predicted poor outcome with area under the receiver-operator curve of 0.67 in both groups.

CONCLUSIONS

Those with functional and recognised pathophysiological neurological disorder share similar outcomes, clinical trajectories, and poor prognostic markers in multivariable models. Prediction of outcome at a patient level was not possible using the baseline data in this study.

Evaluating the Psychometric Properties of the Psychological Capital Questionnaire (PCQ) in Patients with Parkinson's Disease

BACKGROUND

Positive personality resources have demonstrated the ability to positively impact health outcomes.

OBJECTIVE

To examine the psychometric properties of the original Psychological Capital Questionnaire (PCQ-24) in patients with Parkinson's disease (PD).

METHODS

A sample of 114 individuals with PD completed the PCQ-24, and via a latent factor modeling framework exploratory and confirmatory factor analyses were conducted to evaluate the psychometric properties in people with PD.

RESULTS

Exploratory factor analysis (EFA) revealed that both the efficacy and hope scales were reliable (Cronbach's alpha = 0.87 and 0.86, respectively) and had statistically acceptable validity with strong factor loadings all above the practical threshold of 0.60. The resilience and optimism scales were also reliable (Cronbach's alpha = 0.78 and 0.73, respectively) but had only moderately acceptable validity in part due to three reverse-scored items (i.e., No. 13, 20, & 23) with weak factor loadings of 0.26, 0.46, and 0.50, respectively. After excluding these at-risk items, the overall factor loadings for resilience and optimism were significantly improved at the acceptable above 0.60. The CFA results confirm a statistically acceptable model fit for the modified version (only 21-items) of the PCQ in the PD sample.

CONCLUSION

Both EFA and CFA analyses provide statistical evidence supporting the modified PCQ version and demonstrate better test validity and reliability in the PD population. The refined PCQ form is both effectively shorter and psychometrically superior to the original and has promise in investigating health outcomes in people with PD.

Psychological interventions for people with Parkinson's disease in the early 2020s: Where do we stand?

PURPOSE

To explore the heterogeneity of the literature on psychological interventions for psychological difficulties in people with Parkinson's disease (PD).

METHODS

A scoping review was performed across five major databases (MEDLINE Complete, PsycINFO, CINAHL, Academic Search Ultimate, and Cochrane Library) up to June 2020.

RESULTS

From an initial return of 4911 citations, 56 studies were included, of which 21 were RCTs. A relatively wide range of therapeutic models have been adopted with people with PD, from common therapies such as cognitive behavioural therapy (CBT) and mindfulness, to less frequent approaches, for example, acceptance and commitment therapy (ACT) and psychodrama. The clinical implications of the findings are discussed, and suggestions are provided for future research on intervention studies and key psychological outcomes.

CONCLUSIONS

CBT appears to be effective in treating depression and sleep disorders in people with PD, while psychoeducation programmes alone should be avoided. The use of CBT to improve anxiety, quality of life, and impulse control, as well mindfulness-based interventions, should be undertaken with some caution because of insufficient research and inconsistent results. As we enter the new decade, more high-quality evidence is required for psychological interventions in people with PD in general and to corroborate preliminary positive findings on the adoption of less frequent approaches such as ACT.

PRACTITIONER POINTS

Parkinson's disease is a progressive neurodegenerative condition associated with several psychological difficulties which be targeted by psychological interventions. Currently, cognitive behavioural therapy (CBT) can be recommended to treat depression and sleep disorders in people with Parkinson's, while psychoeducation alone should be avoided. Caution is advised regarding the use of CBT and mindfulness-based interventions to improve anxiety, quality of life, and impulse control. Further evidence is required for less common approaches, such as acceptance and commitment therapy, psychodrama, and EMDR.

Does perceived control mediate the relationship between stigma and well-being for individuals with Parkinson's disease?

INTRODUCTION

Stigma is a known correlate of well-being for many neurological conditions. Perceived control is also an important variable in models of adaptation to living with a health condition. The purpose of this study was to investigate whether the perception of control mediates the relationship between stigma and well-being in people with Parkinson's disease.

METHODS

Two hundred and twenty-nine individuals completed quantitative measures of stigma and perceived control, and a full exploration of the concept of well-being (including health-related quality of life, depression, anxiety, stress and positive affect). A series of mediation models investigated whether perceived control mediated the relationship between stigma and each measure of well-being.

RESULTS

Mediational regression analyses indicated that the perception of control mediated the relationship between stigma and health-related quality of life, depression and positive affect. Perceived control did not, however, mediate the relationship between stigma and anxiety nor between stigma and stress.

CONCLUSIONS

These findings suggest that in people with Parkinson's disease, perceived control may play an important role in explaining the relationship between stigma and some aspects of well-being. Both stigma and perceived control should be considered within clinical and everyday environmental settings for individuals with Parkinson's disease. Interventions which focus on both reducing stigma and increasing perceived control are outlined.

Which factors impact on quality of life for adults with blepharospasm and hemifacial spasm?

Purpose: Benign essential blepharospasm (BEB) and hemifacial spasm (HFS) are debilitating conditions causing spasms to the eyes and/or face and can significantly impact on quality of life (QoL). Initial research has highlighted potential factors impacting on QoL in BEB, but there remains a wealth of demographic, clinical, and psychosocial factors that may contribute to QoL but have not received attention. Methods: Cross-sectional baseline data were collected before a single-masked randomised controlled trial from 130 adults with BEB and HFS recruited from botulinum toxin clinics at Moorfields Eye Hospital, London. QoL was measured using the 24-item Craniocervical Dystonia Questionnaire (CDQ24), which provides a total score and five subscale scores relating to Stigma, Emotional state, Pain, Activities of daily living (ADL), and Social/family life. Treating clinicians provided clinical data. Hierarchical multiple regressions were performed on this baseline data to identify significant predictors of QoL. Results: ADL and Stigma were the areas most impacted upon whilst patients experienced better adjustment in relation to Pain, Social/family life, and Emotional state. CDQ24 Total scores were explained by the model (80% variance) and were significantly associated with appearance concerns, emotional representations, perceived negative consequences of the condition, mood, and dose of botulinum toxin. Conclusions: Patients with BEB and HFS report a detrimental impact on ADL and perceived stigma in relation to their condition. Predominantly, individual perceptions and mood are associated with QoL in this population, rather than demographic and clinical factors, signifying areas to target in the design of future healthcare services or interventions.

Understandings of psychological difficulties in people with the Huntington's disease gene and their expectations of psychological therapy

OBJECTIVES

This study sought to investigate how people who had tested positive for the Huntington's disease (HD) gene mutation understood and experienced psychological distress and their expectations of psychological therapy.

DESIGN

A qualitative methodology was adopted involving semi-structured interviews and interpretative phenomenological analysis (IPA).

METHOD

A total of nine participants (five women and four men) who had opted to engage in psychological therapy were recruited and interviewed prior to the start of this particular psychological therapeutic intervention. Interviews were transcribed verbatim and analysed using IPA whereby themes were analysed within and across transcripts and classified into superordinate themes.

RESULTS

Three superordinate themes were developed: Attributing psychological distress to HD: 'you're blaming everything on that now'; Changes in attributions of distress over time: 'in the past you'd just get on with it'; and Approaching therapy with an open mind, commitment, and hope: 'a light at the end of the tunnel'.

CONCLUSION

Understandings of psychological distress in HD included biological and psychological explanations, with both often being accepted simultaneously by the same individual but with biomedical accounts generally dominating. Individual experience seemed to reflect a dynamic process whereby people's understanding and experience of their distress changed over time. Psychological therapy was accepted as a positive alternative to medication, providing people with HD with hope that their psychological well-being could be enhanced.

PRACTITIONER POINTS

People with the Huntington's disease gene mutation have largely biomedical understandings of their psychological distress. This largely biomedical understanding does not, however, preclude them for being interested in the potential gains resulting from psychological therapy. The mechanisms of psychological therapy should be explained in detail before therapy and explored along with current attributions of distress.

Understanding uncertainty in young-onset Parkinson disease

Objectives Individuals living with young-onset Parkinson's disease compose a rare subtype of a disease typically associated with older age. Situated within a large grounded theory study exploring information behavior, this paper describes the core category of the theory, i.e. uncertainty. Methods Data were collected with 39 individuals living with young-onset Parkinson's disease who took part in in-depth interviews, focus groups and/or an online discussion board. Fourteen autobiographies written by individuals living with young-onset Parkinson's disease were also used as data sources. Results Through experiencing young-onset Parkinson's disease, participants were confronted with uncertainty along two main lines. First, they experienced uncertainty with respect to their identities as young- and middle-aged adults, deviating from the idealized age-graded life path marked out within their socio-cultural context. Second, they experienced uncertainty with respect to their functioning, as the heterogeneous nature of Parkinson's progression meant that it would not be possible to chart how their disease would change over time. This uncertainty was associated with feelings of lost control over their lives and increased grief. Discussion With a deeper appreciation for how uncertainty is experienced in the lives of those with young-onset Parkinson's disease, health professionals may be better prepared to discuss these issues with patients and provide support and resources.

The Common Sense of Counseling Psychology: Introducing the Common-Sense Model of Self-Regulation

The goal of therapy is typically to improve clients' self-management of their problems, not only during the course of therapy but also after therapy ends. Although it seems obvious that therapists are interested in improving client's self-management, the psychotherapy literature has little to say on the topic. This article introduces Leventhal's Common-Sense Model of Self-Regulation, a theoretical model of the self-management of health, and applies the model to the therapeutic process. The Common-Sense Model proposes that people develop illness representations of health threats and these illness representations guide self-management. The model has primarily been used to understand how people self-manage physical health problems, we propose it may also be useful to understand self-management of mental health problems. The Common-Sense Model's strengths-based perspective is a natural fit for the work of counseling psychologists. In particular, the model has important practical implications for addressing how clients understand mental health problems over the course of treatment and self-manage these problems during and after treatment.

Differences and similarities in the trajectories of self-esteem and positive and negative affect in persons with chronic illness: an explorative longitudinal study

BACKGROUND

Chronic illness is a risk factor for low self-esteem, and the research literature needs to include more studies of self-esteem and its development in chronic illness groups using longitudinal and comparative designs. The aim of this study was to explore the trajectories of self-esteem and of positive and negative affect in persons with morbid obesity and in persons with chronic obstructive pulmonary disease (COPD).

METHODS

Patient education course attendants in Norway having morbid obesity (n=139) or COPD (n=97) participated in the study. Data concerning self-esteem, positive and negative affect, and sociodemographic background were collected at the start and at the end of the patient education, with subsequent follow-ups at 3, 6, and 12 months. Data were analyzed using linear mixed models for repeated measures.

RESULTS

Taking all measurements into account, our data revealed a statistically significant increase in self-esteem for participants with morbid obesity but not for those with COPD. There were no significant differences in levels of negative and positive affect between the two groups, and the time-trajectories were also similar. However, participants in both groups achieved lower levels of negative affect for all the successive measurement points.

CONCLUSION

An increase in self-esteem during the first year after the patient education course was observed for persons with morbid obesity, but not for persons with COPD. Initial higher levels of self-esteem in the participants with COPD may indicate that they are less troubled with low self-esteem than people with morbid obesity are. The pattern of reduced negative affect for both groups during follow-up is promising.

Psychological Predictors of Anxiety and Depression in Parkinson's Disease: A Systematic Review

OBJECTIVES

Parkinson's disease (PD) is a neurodegenerative disorder, affecting the motor system with psychological difficulties also frequently reported. While explanations for psychological difficulties are historically situated within a biomedical framework, more recently the relevance of psychological determinants has become a research focus. This review therefore examines this relationship with the two most commonly reported psychological difficulties (anxiety and depression) in people with PD.

METHOD

Databases were systematically searched up to December 17, 2013, identifying 24 studies meeting inclusion criteria.

RESULTS

Significant predictors of heightened anxiety and depression included increased emotion-focused coping; less problem-focused coping; lower perceived control; more dominant beliefs about PD as part of a person's identity and influence on life; less social support and more avoidant personality types.

CONCLUSIONS

Relationships between some specific psychological predictors and depression and anxiety seem well supported. The complexity of relationships between these psychological determinants should be taken into consideration when delivering psychological interventions.

How do people live life successfully with Parkinson's disease?

AIMS AND OBJECTIVES

The aim of this paper is to explore how people live life successfully with Parkinson's disease and what contributed to the level of success.

OBJECTIVES

To examine the level of success as defined by people with Parkinson's disease. To find what contributed to the level of success.

BACKGROUND

Self-care support has gained importance for supporting people with their chronic diseases including Parkinson's disease. Although self-care and life adjustments can improve patients' general well-being, it is unclear which approaches best facilitate positive adjustments to illness.

DESIGN

Semi-structured interviews with participants with Parkinson's disease.

METHODS

Eight participants living with Parkinson's disease for 2-16 years were recruited from a Parkinson's disease voluntary group in the UK. Interviews covered their perceived level of success and the factors which they perceived led to that success. Thematic analysis was used to analyse the data.

RESULTS

Participants rated a high level of success in living with Parkinson's disease with an average personal rating 75/100 despite facing difficulties. Successful living was perceived to have taken place when people were either (1) able to return to their usual state of health or (2) considered themselves to be stable within a new/readjusted state of health. Aspects which were perceived to support positive psychosocial adjustment included a positive mindset, determination, acceptance of new challenges and family support.

CONCLUSION

Maintaining usual life and physical ability is the major concern among the people with Parkinson's disease. It would be helpful for health care professionals to identify what constitutes a 'usual' life for that person and to support them to develop a positive mindset and acceptance of new challenges, drawing on the determination of the person as well as any available family support.

RELEVANCE TO CLINICAL PRACTICE

In supporting self-care, it is helpful to gain information about the subjective experience of living with Parkinson's disease including their perceived level of success at the time and what led to that perceived success for that person.

The experience of Parkinson's disease: a systematic review and meta-ethnography

There has been little attempt to summarise and synthesise qualitative studies concerning the experience and perception of living with Parkinson's disease. Bringing this information together would provide a background to understand the importance of an individual's social identity on their well-being and hope. Three primary aims were identified (a) understanding the importance of social identity and meaningful activities on individuals' well-being, (b) identifying factors and strategies that influence well-being and hope, and (c) establishing a model that relates to an individual's hope and well-being. Three stages were undertaken including a traditional electronic search, a critical appraisal of articles, and a synthesis of studies. Qualitative articles were included that considered the experience of living with Parkinson's disease. Thirty seven articles were located and included in the review. Five themes were identified and the themes were used to inform development of a new model of hope enablement. The current review furthered understanding of how physical symptoms and the experience of Parkinson's disease affect the individual's well-being and hope. Social identity was established as a key factor that influenced an individual's well-being. Being able to maintain, retain, or develop social identities was essential for the well-being and hope of individuals with Parkinson's disease. Understanding the factors which prevent or can facilitate this is essential.

Factors associated with self-esteem in persons with morbid obesity and in persons with chronic obstructive pulmonary disease: a cross-sectional study

Living with chronic illnesses can be stressful and may negatively impact persons' self-esteem. Personal factors, like self-efficacy and illness perceptions, and also factors related to the environment, activity, and participation may be associated with self-esteem in chronic illness populations. This cross-sectional comparative study explored sociodemographic variables, work, physical activity, illness perceptions, and general self-efficacy in relation to self-esteem in persons with morbid obesity and in persons with chronic obstructive pulmonary disease (COPD). The study had a cross-sectional design. A total of 223 eligible participants were recruited from patient education courses, and data were collected at baseline. Self-esteem was measured with The Rosenberg self-esteem scale; the general self-efficacy scale was used to measure self-efficacy, and brief illness perception questionnaire was also used. This is an instrument assessing cognitions about the illness and emotional responses towards it. Multivariate linear regression was used in the statistical analyses. In obese participants (n = 134), higher self-esteem was associated with lower emotional response, a shorter timeline, and higher general self-efficacy. In COPD participants (n = 89), higher self-esteem was associated with higher general self-efficacy. The independent variables accounted for 42.9% (morbid obesity) and 49.4% (COPD) of the self-esteem variance. In participants in both illness groups, higher self-efficacy was associated with increased self-esteem. A shorter timeline and lower emotional response to illness was related to higher self-esteem only for the obese participants. The results indicate that believing in one's capacity to cope with everyday challenges is important for self-esteem in persons with morbid obesity and in persons with COPD, whereas illness perceptions related to the duration of illness and the coping with emotions also is important for self-esteem in persons with morbid obesity.

Reformulating psychological difficulties in people with Parkinson's disease: the potential of a social relational approach to disablism

Research investigating the psychological difficulties experienced by people with Parkinson's disease (PD) is dominated by individualistic neurobiological and psychological perspectives. Therefore, this opinion paper draws on a reformulation of the social model of disability, Thomas' (1999) and (2007) social relational approach to disablism, to offer an alternative way of conceptualising psychological difficulties experienced by people with PD. This opinion paper explores the ways in which socially imposed restrictions and stigma may contribute to psychological difficulties by using Thomas' (2007) concept of psychoemotional disablism. By using the lens of psychoemotional disablism, this paper demonstrates that people with PD can be exposed to stigmatising attitudes and interactions which could contribute to restrictions, feelings of shame, and psychological difficulties such as depression. Accordingly, it is argued that further attention to the link between psychological difficulties and social dimensions of disablism in PD is needed in both research arenas and clinical practice to broaden understandings and interventions for people with PD.
