An exploration of worry content and catastrophic thinking in middle-aged and older-aged adults with and without Parkinson's disease

Psychological Factors Associated With Fear of Falling Avoidance Behavior in Parkinson's Disease: The Role of Depression, Anxiety, and Catastrophizing

PURPOSE

The purpose of this study was to examine the relationship between psychological factors (depression, anxiety, and catastrophizing) and fear of falling avoidance behavior (FFAB) among individuals with Parkinson's disease (PD).

METHODS

A secondary analysis of cross-sectional data from 59 individuals with PD using hierarchical multiple regression.

RESULTS

Disease severity (Movement Disorder Society - Unified PD Rating Scale) and catastrophizing (Consequences of Falling Questionnaire (CoF)) explained approximately 48.2% of the variance in the FFAB Questionnaire scores (P < .001). Catastrophizing was the only significant psychological variable (P < .001). The damage to identity subscale of the CoF was significant in the final model (P < .001).

CONCLUSIONS

Catastrophizing about the consequences of falls explained the largest portion of variability in FFAB after controlling for disease severity. Catastrophizing about the immediate consequences of falling may play a prominent role in FFAB and may be a potential treatment target for mitigating FFAB.

Perceptions and meanings of living with Parkinson's disease: an account of caregivers lived experiences

Purpose: Current study looked into caregiving process of those dealing with family members suffering from Parkinson’s disease, within the changing social milieu in India. It aimed to understand the experiential and existential impact on the lifeworld of caregivers.

Method: Narrative interviews of 10 female caregivers referred by neurologists were gathered. Employing Existential Phenomenological Analysis, the caregiver experiences were understood phenomenologically within an existential framework, six themes were generated.

Results: Themes were – Becoming a caregiver: Undertaking immeasurable and unrelenting responsibilities; Rising patient-hood of one’s family member: pain of losing the person in the patient; Experience of altered temporality: living in pain with the uncertainty and duration of the disease; Encountering meaninglessness: dwindling faith in principles of life; Existing as a “Being For” and not “Being With”: a caregiver’s self-estrangement and blurring of Identity and lastly Self-Preservation through brief moments of respite: coping with caregiving.

Conclusion: The study illuminated how caregiving is experienced by an individual at a process and psychic level by shedding light on the conflicts, concerns and exhaustions endured by them. Adopting an existential approach in healthcare setups can aid in moving closer to felt experiences of these caregivers and in developing integrative and meaningful interventions for enhancing their well-being.

Health anxiety and illness-related fears across diverse chronic illnesses: A systematic review on conceptualization, measurement, prevalence, course, and correlates

BACKGROUND

Patients with chronic diseases commonly report fears of illness or symptoms recurring or worsening. These fears have been addressed from an illness-specific perspective (e.g., fear of cancer recurrence), a generic illness perspective (e.g., fear of progression), and a psychiatric perspective (DSM-5 illness anxiety disorder and somatic symptom disorder). The broader concept of health anxiety (HA) can also be applied to patients with a chronic disease. This review was conducted to investigate the conceptual, theoretical, measurement-overlap, and differences between these distinct perspectives. We also aimed to summarize prevalence, course, and correlates of these fears in different chronic illnesses.

METHODS

We used PsycINFO, PubMED, CINAHL, Web of Science, SCOPUS, and PSYNDEX to conduct a systematic review of studies pertaining to these fears in chronic illness published from January 1996 to October 2017. A total of 401 articles were retained.

RESULTS

There were commonalities across different conceptualizations and diseases: a high prevalence of clinical levels of fears (>20%), a stable course over time, and a deleterious impact on quality of life. Reviewed studies used definitions, models, and measures that were illness-specific, with only a minority employing a psychiatric perspective, limiting cross-disease generalizability. There appears to be some applicability of DSM-5 disorders to the experience of fear of illness/symptoms in patients with a chronic illness. While conceptualizing HA on a continuum ranging from mild and transient to severe may be appropriate, there is a lack of agreement about when the level of fear becomes 'excessive.' The definitions, models, and measures of HA across chronic illnesses involve affective, cognitive, behavioral, and perceptual features.

CONCLUSIONS

The concept of HA may offer a unifying conceptual perspective on the fears of illness/symptoms worsening or returning commonly experienced by those with chronic disease.

Human behavioral assessments in current research of Parkinson's disease

Parkinson's disease (PD) is traditionally classified as a movement disorder because patients mainly complain about motor symptoms. Recently, non-motor symptoms of PD have been recognized by clinicians and scientists as early signs of PD, and they are detrimental factors in the quality of life in advanced PD patients. It is crucial to comprehensively understand the essence of behavioral assessments, from the simplest measurement of certain symptoms to complex neuropsychological tasks. We have recently reviewed behavioral assessments in PD research with animal models (Asakawa et al., 2016). As a companion volume, this article will systematically review the behavioral assessments of motor and non-motor PD symptoms of human patients in current research. The major aims of this article are: (1) promoting a comparative understanding of various behavioral assessments in terms of the principle and measuring indexes; (2) addressing the major strengths and weaknesses of these behavioral assessments for a better selection of tasks/tests in order to avoid biased conclusions due to inappropriate assessments; and (3) presenting new concepts regarding the development of wearable devices and mobile internet in future assessments. In conclusion we emphasize the importance of improving the assessments for non-motor symptoms because of their complex and unique mechanisms in human PD brains.
