The development of the Internal Resource Perception Scale: Validity and reliability.

Area of Science:

• Psychometric assessment
• Psychological well-being
• Personal growth

Background:

• Perception of internal resources significantly impacts mental well-being and personal development.
• No existing tools specifically measure personal perceptions of internal resources.
• A psychometric study was conducted in Thailand to address this gap.

Purpose of the Study:

• To develop and validate a tool for assessing personal perceptions of internal resources within the Thai population.
• To create the Internal Resource Perception Scale (IRPS).

Main Methods:

• The Internal Resource Perception Scale (IRPS) was developed using literature reviews, focus groups, and expert input.
• Content validity was established by psychotherapy and inner growth experts.
• Exploratory and confirmatory factor analyses were performed on data from 514 Thai adults.

Main Results:

• The 25-item IRPS, comprising four factors (Compassionate and Ethical Nature, Adaptable Mindset, Responsible Spirit, Logical Perspective), explained 62.4% of the variance.
• The scale demonstrated excellent internal consistency (McDonald's omega = .96) and strong psychometric properties.
• IRPS scores correlated positively with well-being measures and negatively with distress measures.

Conclusions:

• The IRPS is a psychometrically sound instrument for evaluating individuals' perceptions of their internal resources.
• The scale can enhance self-awareness, learning, and personal growth.
• Future research should investigate the IRPS's clinical applications.
