Description of intervention(s) / exposure
The intervention will be conducted a week after the baseline assessment (Time 1). The intervention will include 6 weekly manualised Cognitive Behaviour Therapy (CBT) sessions tailored to address Parkinson's disease issues. It will be delivered in a dyad of PD patients and caregivers. Caregivers will be invited to engage in the therapy sessions to support the person with PD. Each therapy session will last 1-1.5 hours and will be conducted face-to-face by a clinical psychologist or a provisionally registered psychologist undergoing advanced postgraduate training at the University of Queensland’s School of Psychology. Intervention sessions will be conducted at the UQCCR or UQ Psychology Clinic at St. Lucia. Record of attendance will be obtained at each therapy session.
During the therapy sessions PD patients and their caregivers will learn, and practice techniques concerning the following topics:
- Psychoeducation, and symptom monitoring focused on PD-specific anxiety symptomatology such as anxiety associated with (i) motor symptoms, (ii) motor fluctuations, (iii) dyskinesias, and (iv) PD medication induced addictive behaviours (e.g. impulse control disorders, dopamine dysregulation syndrome),
- Calming techniques of deep breathing,
- Relaxation using progressive muscle relaxation or imagery (e.g. people with severe muscular rigidity and associated cramping can find it difficult to practice progressive muscle relaxation),
- Sleep hygiene, and
- Relapse prevention.
PD patients will be encouraged to practice these skills between sessions. To help with this practice PD patients will receive printed material and worksheets during each therapy session, which are to be completed before the next therapy session. Caregivers will be encouraged to help the PD patient they care for to practice the new skills.

Comparator / control treatment
Parkinson's disease (PD) patients with anxiety will be randomly allocated to either the CBT intervention group (group 1) or wait-list control group (group 2). The wait-list control group will receive clinical monitoring and educational material about PD which will cover the following topics: psychoeducation, symptom monitoring, calming techniques of deep breathing, relaxation using progressive muscle relaxation or imagery, sleep hygiene, and relapse prevention. The wait-list group will receive the intervention after group 1 completes the intervention and post clinical assessment (i.e. they will commence intervention after 6 weeks from baseline assessment).

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed.
We will use sealed opaque envelops. Once envelops are given to patients a research assistant who is not involved with assessments will ask patients to reveal their allocation and will further discuss their role in each group. This person will be responsible for liaising with therapists and setting up post assessments.

Statistical methods / analysis
Sample size: To make case-control comparisons pre (Time 1) and post (Time 2) treatment or waitlist conditions, with large effect sizes at 80% with a p value of 0.05, at least 30 PD patients with anxiety are required (Cohen J. A Power Primer. Psychol Bull 1992; 112(1): 155-9). PD patients will be randomly allocated to intervention or waitlist control. In our pilot study, we had an attrition rate of 30%. Therefore, this proposal will require at least 46 PD patients with anxiety to commence the CBT intervention, and thus each group (intention and control) will consist 23 PD patients and 23 carers.
Data analysis: Multilevel linear mixed-effects modelling using “MIXED” procedure in SPSS software package will be used. Separate models will be conducted to analyse outcome measures of each scale outlined above. Change in outcomes between pre (Time 1) and post (Time 2) assessments will be assessed comparing between treatment condition and control condition. A significant Time X Condition interaction will indicate a differential rate of change in outcomes between the intervention and control condition from Time 1 to 2.

Summary
Brief summary
Parkinson’s disease (PD) is an age-related incurable disorder observed in 3% of persons aged 65 years old and over, and 10% of those aged over 80 years old, making it one of the more common neurological disorders of later life. In Australia, 1 in every 340 people lives with this condition. The prevalence of anxiety in PD exceeds 50%, and it is a major contributor to a poor quality of life of patients and caregivers. However, anxiety is poorly identified in PD. There is a paucity of clinical trials primarily focussed on treating anxiety, and there are no evidence based effective and safe pharmacological treatment for anxiety in PD. To complicate matters further, anxiety in PD presents with unique and complex symptomatology which must be understood and addressed if intervention is to be effective. There is an urgent need for empirically validated interventions targeting PD-specific anxiety symptoms for successful treatment. The present study will be the first to provide empirical evidence for Cognitive Behaviour Therapy (CBT) for anxiety by conducting a waitlist-controlled tailored and dyadic CBT trial including PD patients and caregivers. The study also focuses on caregiver well-being and the relationship quality and satisfaction for PD and caregivers. The ultimate goal of the present proposal is to improve diagnosis and treatment of anxiety in PD; thus improve quality of life of patients and their caregivers. METHODS PD patients will be recruited from neurology outpatient clinics in Brisbane. Their carers will also be invited to participate in the study. Apart from neurology outpatient clinics, PD patients and their carers who express interest to participate in PD research through other PD studies, support groups and advertisements will also be recruited. Research design: This study is a randomised wait-list controlled intervention design. PD patients with anxiety will be randomly allocated to either the Cognitive Behaviour Therapy (CBT) intervention group (group 1) or control group. The wait-list control group will receive clinical monitoring and educational material about PD. The wait-list group will receive the intervention after group 1 completes the intervention.
