简要总结
This is a sequential mixed study to test the hypothesized models with seven hypotheses of the relationship between cognitive deficit (subject and objective) and neuropsychiatric symptoms (NPS) among persons with mild cognitive impairment (PwMCI). The study will also examine the psychometric properties of the Chinese version of Mild Behavioural Impairment -Checklist (MBI-C).
详细描述
The primary aim of this study is to test the hypothesized model that explores the moderating roles of neurotic personality, social support and coping style, as well as the mediating role of self-esteem in the relationship between cognitive deficit and NPS. This study will also examine the psychometric properties of the Chinese version of MBI-C.
Specifically, the four objectives of this study are as follows:
- To examine the relationship between cognitive deficit (subjective and objective) and NPS
- To examine the moderating roles of the neurotic trait (neuroticism) and coping resources (coping style and social support), as well as the mediating role of self-esteem in the relationship between cognitive deficit and NPS
- To explore the life experience of PwMCI that help to determine how these factors moderate/ mediate the relationship between cognitive deficit and NPS
- To examine the psychometric properties of the Chinese version of MBI-C among PwMCI in Hong Kong
This sequential mixed study will be conducted in two non-governmental organization in Hong Kong.
For the first and second objective, a descriptive, cross-sectional, correlational approach will be adopted to test the hypothesized models with seven hypotheses of the relationship between cognitive deficit (subject and objective) and NPS. The moderating roles of personality trait (neuroticism) and coping resources (coping styles and social support), as well as the mediating role of self-esteem in such a relationship, will also be explored.

排除标准

结局指标
主要结局
Hong Kong Chinese version of Montreal Cognitive Assessment (HK-MoCA)
时间窗: Baseline
This 12-item instrument will be used to measure cognitive functions including visuospatial functions, naming, verbal memory, abstraction, delay memory, calculation and orientation. Total score ranges from 0 to 30, with lower scores indicating more severe cognitive impairment.
Chinese Version of the Neuropsychiatric Inventory Questionnaire (NPI-Q)
时间窗: Baseline
NPI-Q is a caregiver-administered instrument that assesses measure the frequency and severity of NPS among the participants.This instrument measures 12 domains including delusion, hallucination, anxiety, depression, euphoria, apathy, disinhibition, irritability and aberrant motor behaviour, sleep disturbance and appetite. The instrument will be completed by an informant to rate the frequency of NPS on a four-point scale (1 - sporadically, 4 - very often) and the severity of NPS on a three-point scale (1 - mild, 3 - severe).
Chinese version of Chinese version of Mild Behavioural Impairment -Checklist
时间窗: Baseline
This 34-item questionnaire will be used to measure five domains of NPS, including decreased motivation, emotional dysregulation, impulse dyscontrol, social inappropriateness and abnormal perception or thought content. It involves closed-ended questions on the existence of symptoms followed by a 3-point Likert scale on their severity. Total scores of all domains range from 0 to 102, with higher scores indicating more NPS.
次要结局
- Chinese version of Simplified Coping Scale Questionnaire (SCSQ)(Baseline)
- Chinese version of Multidimensional Scale of Perceived Social Support (MSPSS-C)(Baseline)
- Chinese version of the neuroticism subscale of NEO Personality Inventory (NEO-PI)(Baseline)
- Rosenberg self-esteem scale (RSES)(Baseline)
