Abstract

Objective:

To develop psychosocial adaptation scale for Parkinson's disease (PD) in Chinese population and evaluate its reliability and validity.

Methods:

The items were designed by literature review, expert consultation and semi-structured interview. The methods of corrected item-total correlation, discrimination analysis and exploratory factor analysis were used for items selection. 427 valid scales from PD patients were collected in the study to test the reliability and validity.

Results:

The scale incorporated six dimensions: anxiety, self-esteem, attitude, self-acceptance, self-efficacy and social support, a total of 32 items. The scale possessed good internal consistency. The test-retest correlation coefficient was 0.99 and average content validation rate was 0.97. The Hoehn and Yahr stage were correlated with total score of the scale.

Conclusions:

The psychosocial adaptation scale in this study showed good reliability and validity, it can be used as a reliable and valid instrument to evaluate the psychosocial adaptation of PD objectively and effectively.

Keywords:

Parkinson’s disease psychosocial adaptation reliability scale validity

Parkinson's Disease: Overview

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...
