How effective is virtual reality (VR) therapy in reducing anxiety levels during medical procedures in young patients compared to traditional drug-based treatments?

Independent Variable:
The independent variable in this study is the type of treatment administered to children during medical procedures. Specifically, it includes two levels: VR therapy (non-drug approach) and traditional drug-based treatments.

Level of Measurement for Independent Variable:
The independent variable is categorical with two levels: VR therapy and traditional drug-based treatments. This categorical nature allows for easy comparison between the two types of treatments.

Considerations for Analyzing Data:
When analyzing data related to the independent variable (type of treatment), researchers may use inferential statistical techniques such as chi-square tests or logistic regression to assess the association between the type of treatment and anxiety reduction (Gao et al., 2022). One advantage of analyzing categorical data is the straightforward interpretation of results in terms of treatment effectiveness. However, challenges may arise in ensuring that the groups receiving different treatments are comparable in terms of other relevant factors that could influence anxiety levels (Ferraz-Torres et al., 2023).

Dependent Variable:
The dependent variable in this study is anxiety levels experienced by children during medical procedures. These levels are measured using a recognized anxiety measurement tool.

Level of Measurement for Dependent Variable:
The dependent variable (anxiety levels) is measured on an interval or ratio scale, depending on the specific anxiety measurement tool used. Interval scales assign numerical values to anxiety levels with equal intervals between them, while ratio scales include a true zero point, allowing for ratios to be calculated.

Considerations for Analyzing Data:
Analyzing data related to the dependent variable (anxiety levels) may involve using descriptive statistics such as means and standard deviations to summarize the data (Addab et al., 2022). Additionally, inferential statistical techniques like t-tests or analysis of variance (ANOVA) may be used to compare anxiety levels between the VR therapy group and the traditional treatment group. One advantage of analyzing interval or ratio data is the ability to conduct more sophisticated statistical analyses and derive meaningful conclusions about the magnitude of differences in anxiety levels between groups. However, challenges may include ensuring the reliability and validity of the anxiety measurement tool and controlling for potential confounding variables that could impact anxiety levels.
