- 参与者版本 (CDFAQ-PV) 是一个30项自我报告测量,评估六个认知领域:复杂的注意力,执行功能,学习和记忆,语言,感知运动和社会认知.
- 虽然通报者版本 (CDFAQ-IV) 已经得到验证,但CDFAQ-PV的心理测量特性,特别是其因子结构,需要评估.
研究的目的:
- 在CDFAQ-PV.上进行确认因素分析 (CFA).
- 评估拟议的六因素模型是否符合DSM-5认知领域.
- 评估CDFAQ-PV用于测量老年人认知功能的心理测量有效性.
主要方法:
- 一个377名老年人的样本完成了CDFAQ-PV.
- 使用JASP软件与Lavan R包进行了确认因素分析.
- 一个手动的六因素模型被指定并测试了适合性.
主要成果:
- 该CFA模型显示了显著的整体匹配 (X2 p < .001).
- 对标准化根平均平方余数 (SRMR = .065) 和适应指数的良好性 (GFI = .983) 观察到良好适应指数.

Chronic Kidney Disease II: Clinical Manifestations
520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart Failure III: Clinical Manifestations
436
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Hypertension III: Clinical Manifestations and Diagnostic Studies
437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
