Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Factors Affecting Illness

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness.

Self-Report Tests of Personality

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Area of Science:

Psychology
Public Health
Mental Health Assessment

Background:

The prolonged COVID-19 pandemic necessitates updated tools to assess evolving psychological responses.
Existing measures may not fully capture the multifaceted psychological impact of the pandemic.

Purpose of the Study:

To develop and validate the COVID-19 Impact Scale (CIS).
To measure psychological stress, including emotional responses and daily living difficulties, related to the COVID-19 pandemic.

Main Methods:

Recruited 2152 participants for scale development and validation.
Administered the CIS, Fear of COVID-19 Scale (FCV-19S), and other mental health measures.
Analyzed factor structure, reliability, and validity through exploratory and confirmatory factor analyses.

Main Results:

Exploratory and confirmatory factor analyses supported a robust one-factor structure for the CIS.
The CIS demonstrated strong correlations with depression, anxiety, suicidal ideation, and fear of COVID-19.
The CIS showed superior explanatory power for depression and anxiety compared to the FCV-19S, which lacked significant correlations with well-being and suicidal ideation.

Conclusions:

The CIS is a valid and reliable tool for assessing emotional problems and quality of life deterioration due to the COVID-19 pandemic.
The CIS provides a more comprehensive assessment of pandemic-related psychological distress than the FCV-19S.
Further research directions and study limitations were discussed.
