Quantifying UV Tanning Abuse Liability: A Behavioral Economic Checklist
Many adults continue ultraviolet indoor tanning despite established medical evidence linking the practice to skin cancer. To understand why individuals persist in tanning despite known health hazards, researchers have increasingly examined whether the constellation of behaviors mirrors patterns observed in behavioral addictions. A 2016 study in the Journal of Experimental Analysis of Behavior explored this problem through the lens of behavioral economics. This checklist breaks down how researchers designed the experiment, what the economic model measured, and how to objectively interpret the findings without overstating the results.
Checklist Item 1: Understand the Behavioral Economic Framework
In standard addiction research, economists and psychologists measure "abuse liability" by examining how much of a resource an individual will give up to obtain a specific commodity. When evaluating ultraviolet indoor tanning, investigators adapted tools originally developed to assess substance abuse. Because there has long been a lack of consensus on standard diagnostic tools for identifying tanning addiction tendencies, behavioral economics offers an alternative framework to observe how ultraviolet tanning demand changes under simulated constraints.
By treating tanning sessions as a reinforcing commodity, researchers explore whether users exhibit patterns seen in other behavioral dependencies, such as an unwillingness to decrease consumption even when acquiring the experience demands greater hypothetical sacrifices. Readers exploring this topic can review how health professionals classify indoor tanning and addiction habits versus compulsions.
Checklist Item 2: Examine the Hypothetical Tanning Purchase Task
The core methodology of the 2016 investigation relied on a novel, hypothetical assessment instrument called the Tanning Purchase Task. Rather than relying solely on subjective questionnaires about personal feelings, this instrument asks participants to make decisions regarding hypothetical tanning sessions. Key elements of this experimental method include:
- Hypothetical Decision-Making: Participants report how many ultraviolet indoor tanning sessions they would purchase across simulated conditions.
- Translating Substance Tasks: The purchase task translates paradigms historically used in substance abuse research into a format tailored to tanning sessions.
- Quantifying Core Demand Metrics: The protocol yields specific behavioral economic indicators, primarily focused on the intensity and elasticity of demand.
Checklist Item 3: Differentiate Demand Intensity and Elasticity
A central objective in the 2016 Journal of Experimental Analysis of Behavior study was measuring how behavioral economic demand correlates with an individual's tanning status. Behavioral economics uses two primary indices to describe this relationship:
Intensity of Demand: This metric captures baseline consumption, reflecting how many tanning sessions an individual chooses to obtain when constraints are minimal.
Elasticity of Demand: This metric quantifies how consumption changes as the hypothetical cost or required sacrifice increases. In commodities with high abuse liability, demand tends to be relatively inelastic, meaning users continue to pursue the commodity despite escalating hypothetical costs.
The investigators reported that behavioral economic demand was significantly related to ultraviolet indoor tanning addiction status, showing that the Tanning Purchase Task adequately discriminated between potentially addicted individuals and nonaddicted individuals in the test cohort.
Checklist Item 4: Compare Demand Against Standard Questionnaires
To establish construct validity and convergent validity, the study compared data from the Tanning Purchase Task with two established self-report screening tools adapted from psychiatry:
- The mCAGE: A modified version of the classic screening questionnaire used to evaluate substance dependency.
- The mDSM-IV-TR: Diagnostic criteria adapted from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision.
Statistical comparisons revealed that the behavioral economic indicators aligned with classifications derived from these two common screening instruments. For a closer look at these diagnostic questionnaires, read our guide on assessing tanning dependence and clinical questionnaires.
Checklist Item 5: Note the Design Limits and Pilot Nature
While the study demonstrated that behavioral economic measures render indicators relevant to public health research, readers must evaluate its limitations carefully. The authors noted several boundaries to their findings:
- Between-Groups Design: The research used a between-groups comparison, which provides comparative data but does not establish longitudinal outcomes over time.
- Limited Diagnostic Tools: Convergent validity was established against only two diagnostic screening tools (the mCAGE and mDSM-IV-TR).
- Small, High-Risk Cohort: The investigation analyzed a relatively small sample restricted to high-risk ultraviolet indoor tanning users.
- Pilot Data: The authors explicitly identified the findings as pilot data, serving as an initial step toward quantifying abuse liability rather than a definitive final standard.
Because these conclusions stem from a single pilot study, they should not be viewed as universal diagnostic rules. Anyone struggling with persistent urges to tan despite skin cancer concerns should consult a dermatologist or licensed behavioral health professional for evidence-based guidance.
