Feasibility and Acceptability of a Videoconferencing CBT Intervention for Anxiety in People with Parkinson's Disease.

OBJECTIVES: In people with Parkinson's disease (PwPD), non-motor symptoms such as anxiety are common and have negative impacts on their quality of life. There are currently few interventions that address anxiety in PwPD, and access to diagnosis and treatment is often limited for those living in rural areas. The aim of this study was to evaluate the feasibility and acceptability of a telehealth videoconferencing CBT intervention for anxiety in PwPD. METHODS: A pre- and post-test feasibility study (N = 10) was conducted and evaluated utilizing the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance). RESULTS: Lack of access to the internet and videoconferencing technology were identified as barriers to participation. Physical health issues also impacted recruitment and retention. Non-completers were significantly older and less likely to have a carer involved in the intervention. Clinician adoption of the intervention was low while participant acceptability of videoconferencing technology varied and required carer support. CONCLUSIONS: Providing access to technology and support to overcome technological issues, as well as telehealth training for clinicians, are recommended in future studies to improve recruitment, retention, and implementation. CLINICAL IMPLICATIONS: Identification of barriers and facilitators provides future studies with the knowledge to tailorize their program to better suit PwPD.

A Systematic Review of Psychotherapy Approaches for Anxiety in Parkinson's Disease.

OBJECTIVES: Anxiety is common in Parkinson's disease (PD), negatively impacting daily functioning and quality of life in PD patients and their families. This systematic review evaluates the effectiveness of different psychotherapeutic approaches for reducing anxiety in PD and provides recommendations for clinical practise. METHODS: Following PRISMA guidelines, 36 studies were included and risk of bias was evaluated. RESULTS: We identified cognitive behavioral therapy (CBT), mindfulness-based therapies, acceptance and commitment therapy, and psychodrama psychotherapies. There is good evidence-base for anxiety reduction using CBT approaches, but with mixed results for mindfulness-based therapies. Other therapeutic approaches were under researched. Most randomized control trials examined anxiety as a secondary measure. There was a paucity of interventions for anxiety subtypes. Secondarily, studies revealed the consistent exclusion of PD patients with cognitive concerns, an importance of care partner involvement, and a growing interest in remote delivery of psychotherapy interventions. CONCLUSIONS: Person-centered anxiety interventions tailored for PD patients, including those with cognitive concerns, and trials exploring modalities other than CBT, warrant future investigations. CLINICAL IMPLICATIONS: Practitioners should consider PD-specific anxiety symptoms and cognitive concerns when treating anxiety. Key distinctions between therapeutic modalities, therapy settings and delivery methods should guide treatment planning.
