简要总结
The purpose of this study is to evaluate the efficacy of a cognitive-behavioral treatment, that includes a caregiver-focused social support intervention, for depression in persons with Parkinson's disease.
Individuals who are unable to travel to the study site, but are interested in participating and meet all other eligibility requirements, will be allowed to participate over the phone.
详细描述
Depression is the most common emotional problem found in persons with Parkinson's disease (PD). It causes immense personal suffering and is associated with increased disability and burden to caregivers. Despite the adverse consequences of depression in PD, there are virtually no studies to guide clinical treatment. Several studies are currently examining the effectiveness of antidepressant medication for depression in PD. However, there have been no studies to examine the effectiveness of non-medication approaches, such as cognitive-behavioral therapy, despite the success of these techniques in other populations. Cognitive-behavioral therapy teaches people with PD to become more aware of their thoughts and feelings and to change thinking patterns and behaviors that may be related to symptoms of depression.
The purpose of this study is to determine if cognitive-behavioral therapy--with a caregiver-focused social support intervention--is effective in treating depression in persons with PD. This study will enroll 80 people with PD and their caregivers. Forty participants with PD will be randomly chosen to receive the study treatment in addition to standard medical care. The other 40 will only receive standard medical care and will have the option to receive the study treatment after completing all study assessments (4 months after the initial evaluation).
The study treatment will consist of 10 weekly individual cognitive-behavioral treatment sessions, lasting 1 hour each and modified to meet the unique needs of each individual with PD. Caregivers will attend 4 separate educational sessions-lasting 30 minutes each--designed to provide them with the tools needed to reinforce and supplement the material presented in the cognitive-behavioral sessions. Duration of the study for participants is 15 weeks.
This is the first study to evaluate the impact of a cognitive-behavioral treatment for PD depression in a randomized controlled trial. Information gained from this study may be beneficial in treating depression in persons with PD.

结局指标
主要结局
Hamilton Depression Rating Scale: Baseline
时间窗: 0 weeks
This measure uses the Hamilton Depression Rating Scale (HDRS) to express the average severity of depressive symptoms for a) all participants in the Cognitive-Behavioral Therapy condition and b) all participants in the Standard Medical Care condition, at the outset of the trial. The total score on the HDRS (range = 0 to 84) was used as the outcome measures value, with higher values indicating more severe depressive symptomatology and lower scores representing less severe depressive symptomatology.
Hamilton Depression Rating Scale: Midpoint
时间窗: 5 weeks
This measure uses the Hamilton Depression Rating Scale (HDRS) to express the average severity of depressive symptoms for a) all participants in the Cognitive-Behavioral Therapy condition and b) all participants in the Standard Medical Care condition, after 5 weeks of the trial. The total score on the HDRS (range = 0 to 84) was used as the outcome measures value, with higher values indicating more severe depressive symptomatology and lower scores representing less severe depressive symptomatology.
Hamilton Depression Rating Scale: Follow-Up Evaluation
时间窗: 14 weeks
This measure uses the Hamilton Depression Rating Scale (HDRS) to express the average severity of depressive symptoms for a) all participants in the Cognitive-Behavioral Therapy condition and b) all participants in the Standard Medical Care condition, 4 weeks after the trial ended. The total score on the HDRS (range = 0 to 84) was used as the outcome measures value, with higher values indicating more severe depressive symptomatology and lower scores representing less severe depressive symptomatology.
Hamilton Depression Rating Scale: Endpoint
时间窗: 10 weeks
This measure uses the Hamilton Depression Rating Scale (HDRS) to express the average severity of depressive symptoms for a) all participants in the Cognitive-Behavioral Therapy condition and b) all participants in the Standard Medical Care condition, at the end of the 10 week trial. The total score on the HDRS (range = 0 to 84) was used as the outcome measures value, with higher values indicating more severe depressive symptomatology and lower scores representing less severe depressive symptomatology.
