Cognitive Behavioral Therapy for Anxiety in Parkinson's Disease: A Randomized Controlled Trial.

BACKGROUND: Anxiety disorders are among the most prevalent and disabling neuropsychiatric syndromes in patients with Parkinson's disease (PD), but no randomized controlled treatment trials of anxiety have been published to date. OBJECTIVE: The aim of this study was to assess the effectiveness of cognitive behavioral therapy (CBT) in the treatment of anxiety in patients with PD. METHODS: Forty-eight patients with PD with anxiety were randomized 1:1 between CBT and clinical monitoring only (CMO). The CBT program was developed to specifically address anxiety symptoms in PD and consisted of 10 weekly sessions. Assessments were conducted by blinded assessors at baseline, at the end of the intervention, after 3 months, and after 6 months (CBT group only). Main outcome measures were the Hamilton Anxiety Rating Scale (HARS) and the Parkinson Anxiety Scale (PAS). RESULTS: Both the CBT and CMO groups showed clinically relevant improvement. Although there was no between-group difference in outcome on the Hamilton Anxiety Rating Scale (6.7-point reduction in the CBT group versus 3.9-point reduction in the CMO group; P = 0.15), there was both a statistically significant and a clinically relevant between-group difference on the total PAS in favor of CBT (9.9-point reduction in the CBT group versus 5.2-point reduction in the CMO group; P = 0.012), which was due to improvement on the PAS subscales for episodic (situational) anxiety and avoidance behavior. This greater improvement was maintained at 3- and 6-month follow-ups. CONCLUSION: CBT is an effective treatment for anxiety in patients with PD and reduces situational and social anxiety, as well as avoidance behavior. © 2021 The Authors.

Development of a Screening Tool for Assessing Sexual Difficulties Among Patients with Parkinson's Disease: The PD-SDS.

Background: People with Parkinson's disease (PwPD) exhibit various sexual difficulties (SDs) that may be due to motor and/or nonmotor symptoms or the use of antiparkinsonian medication. SDs are often underreported by PwPD and underexplored by physicians. Objective: This study aimed to explore the SDs experienced by PwPD and create a scale for assessing them. Methods: A corpus of items was generated from semistructured interviews to represent the experience of PwPD as closely as possible. The number of items was reduced according to the psychometric properties, and the scale's structure was subsequently examined. The final phase consisted of measuring the scale's validity and reliability. Results: After assessment of the original corpus of 59 items by PwPD and clinicians, a 25-item version was obtained. The analysis of item properties led to the removal of fifteen items. An exploratory factor analysis of the first 10-item version with a first PwPD sample identified four components of the SDs among PwPD: "low sexual esteem," "sexual displeasure," "impact on sexual position" and "hypersexuality." With a second PwPD sample, a confirmatory factor analysis demonstrated a satisfactory fit between the model with four components and the data. The 10-item scale had good internal consistency and good temporal reliability. Conclusions: The Parkinson's Disease Sexual Difficulties Scale (PD-SDS) is a valid screening tool that facilitates the investigation of and communication about PD-related SDs. It is intended to improve the identification of vulnerable PwPD and to target the domain of sexual experience impacted by PD to better support PwPD.

Dealing with the diagnosis of Parkinson's disease and its implications for couple functioning in the early stage: An interpretative phenomenological analysis.

BACKGROUND: For couples facing Parkinson's disease, marital relationships are significantly impacted, even at the early stages of the disease. However, very few studies have explicitly explored the functioning of the couple and how both partners deal with Parkinson's disease. The aim of this study was to explore the experiences and strategies of couples facing Parkinson's disease in the early stage using dyadic interpretative phenomenological analysis. METHODS: Fifteen couples agreed to participate in the study. Semistructured interviews were conducted with each partner separately regarding his or her individual experience with Parkinson's disease, the couple's history, the impact of the diagnosis on the functioning of the couple, and his or her projections for the future. RESULTS: Three higher-order themes emerged from the analyses. The first theme, "Being tested by the diagnosis", highlights 4 dyadic configurations according to the individual's and the couple's capacity for adjustment following the diagnosis: "noncongruent", "collapsed", "relieved" and "avoidant". The second theme, "Talking about everything except the disease", underlines that communication about the disease is often avoided both within the couple and with relatives to protect the persons with Parkinson's disease or respect their wishes. The third theme, "Supporting each other", describes the different levels of harmony between the two partners in the management of daily life and symptoms and their relational impacts. CONCLUSION: These results allow us to better understand the experiences of both partners and to highlight the importance of promoting better acceptance of the diagnosis by persons with Parkinson's disease to allow better communication between partners and with relatives. Such support prevents disease-specific distress and facilitates better adjustment in the later stages of the disease.

Couples facing the "honeymoon period" of Parkinson's disease: A qualitative study of dyadic functioning.

INTRODUCTION: The public health issue of the Parkinson's disease (PD) has led to a great deal of research that has highlighted the individual challenges faced by the person with the Parkinson's disease (PwPD) and the caregiving spouse. Few studies, however, have sought to understand the functioning of couples facing PD, by differentiating each stage, each of which has its own issues. In particular, the "honeymoon period", characterized by a symptomatic respite allowed by the effectiveness of treatments for motor symptoms, has been poorly documented, especially at the dyadic level. DESIGN AND METHOD: This qualitative study, based on Interpretative Phenomenological Analysis, aimed to understand the experience of couples and their functioning at this stage. Fifteen couples participated in separate semi-structured interviews for each partner. The analyses highlighted four dyadic dynamics, which call into question the relevance of the term "honeymoon" to describe the experience of couples. RESULTS: While some couples appear to adjust by means of flexible functioning and a positive reinterpretation of this experience, other dyads oscillate between rigid hyperprotection in the face of perceived distress or a vicious circle of control/avoidance and, in some cases, gradually slipping towards the erosion of the relationship. DISCUSSION: These results show that the relational difficulties suffered by partners at this stage should be taken into account as soon as possible after the diagnosis. Strengthening the communication and the togetherness between partners, as well as working on dyadic emotional regulation, are particularly relevant options for these couples.

Relationship Dynamics of Couples Facing Advanced-Stage Parkinson's Disease: A Dyadic Interpretative Phenomenological Analysis.

BACKGROUND/OBJECTIVE: Several studies have examined the impact of Parkinson's disease (PD) on the quality of couples' relationships. To date, few studies have explored how couples experience their relationship dynamic by taking into account the disease stage. The objectives of this study were to understand the experience of each partner and to study the mechanisms that underlie their couple organization in the advanced stage of PD. METHODS: Semistructured individual interviews conducted with fifteen patients and their partners were the subject of a dyadic interpretative phenomenological analysis. RESULTS: Three themes were identified from the analysis: the first, "A Closeness That Separates," allows the identification of different patterns of interactions that lead to emotional distancing between the partners; the second, "The Adversity Is Not Unbearable, But Going It Alone Would Be," emphasizes the importance of how the assisting partner provides support; and the third, "Be Prepared for Anything and Facing an Uncertain Future," reveals the extent and modes of the dyadic regulation of the emotions linked to what the future may hold. CONCLUSION: Psychological support is important to help couples express both their feelings and their respective needs in the evolving context of PD.

Living as a couple with anorexia nervosa: A dyadic interpretative phenomenological analysis.

This study examined the difficulties couples face in relation to anorexia nervosa. Using interpretative phenomenological analysis, five couples in which one of the partners lives with anorexia nervosa were interviewed separately. The findings are conceptualized into three areas: first, the encounter 'at the crossroads between remission and relapse'; second, the way that 'anorexia reveals itself'; and finally, the way the 'ménage à trois' works, including the illness fully as part of the couple. Psychotherapists should take into account the context of the couple and the complex interaction between the couple and the illness to support both partners' development of appropriate responses.
