Summary
The Chinese version of the Health Behavior Inventory - Short Form (HBI-SF) demonstrates strong reliability and validity. This validated health behavior measurement tool is now available for use in Chinese populations.
Area of Science:
- Psychometrics
- Health Behavior Measurement
- Cross-cultural Adaptation
Background:
- Health behavior significantly impacts health status, necessitating validated measurement tools.
- The Health Behavior Inventory - Short Form (HBI-SF) is a validated instrument in multiple countries.
- Previous research has established the HBI-SF's utility in diverse populations.
Purpose of the Study:
- To translate the HBI-SF into Chinese.
- To evaluate the psychometric properties of the translated Chinese version of the HBI-SF.
- To ensure the reliability and validity of the Chinese HBI-SF for health behavior assessment.
Main Methods:
- A two-phase methodology was employed, including cross-cultural adaptation and psychometric evaluation.
- Classical Test Theory (CTT) and Item Response Theory (IRT) were utilized to assess reliability and validity.
- The study involved 1058 participants, with 1036 completing the questionnaire; 518 participants were analyzed for CTT and 518 for IRT.
Main Results:
- Confirmatory factor analysis supported a four-factor model with acceptable goodness-of-fit indices.
- Reliability indices (internal consistency, composite reliability, person separation reliability) met acceptable thresholds.
- Item Response Theory analysis indicated that items fit the Rasch model, with two items showing differential item functioning.
Conclusions:
- Both Classical Test Theory and Item Response Theory analyses confirm favorable reliability and validity.
- The Chinese version of the HBI-SF is a psychometrically sound instrument for measuring health behavior.
- This validated tool can be effectively used in Chinese-speaking populations for health behavior research and practice.

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.

Cochran's Q Test is a nonparametric statistical test used to determine if there are potential differences in the outcomes of three or more related groups on a binary (yes/no) or dichotomous outcome. It is essentially an extension of the McNemar Test, which is limited to two related samples - Cochran's Q test can handle three or more related samples, making it more versatile in scenarios where subjects are measured under multiple conditions. The test statistic follows a Chi-Square...
