Description

The Multidimensional Health Locus of Control [AQ-18] is an assessment tool that measures individuals’ perceptions regarding their health and the influence they believe they or others have on their health status. Participants evaluate to what extent they believe their health is affected by internal factors (e.g., their personal actions) or external factors (e.g., luck, other people).

Data Analysis and Use

Data analysis from the AQ-18 includes:

Scoring: Participants rate statements on a Likert scale. Higher scores indicate a greater belief in the corresponding dimension of locus of control.

Descriptive Statistics: Calculation of the mean and standard deviation to determine the overall perception of locus of control in a group.

Correlation: Examination of the relationship between locus of control and factors such as age, gender, or psychological conditions.

Comparative Analysis: Investigation of differences between various groups (e.g., individuals with different education levels or socioeconomic conditions).

Objective

The objective of the AQ-18 is to understand how people perceive their health and the influence of factors they believe affect it, with the aim of promoting health self-management and well-being.

Calibration

The calibration of the AQ-18 involves the process of adjusting the tool for use in different populations. This process includes:

Cross-Cultural Studies: Testing the scale in different cultural and social contexts to ensure its appropriateness.

Reliability Analysis: Using techniques such as Cronbach’s alpha to ensure the consistency of the questions.

Validity Testing: Assessing the ability of the scale to reflect the actual experiences and perceptions of participants regarding their health.
