Loss Aversion and Current, Former, and Never-Smoking Status.

INTRODUCTION

Loss aversion (LA) is a bias in decision-making wherein potential losses have a greater influence on choices than equivalent gains. Such a bias may protect individuals from harm. Consistent with this idea, lower LA has been measured in individuals who endorse current cigarette smoking as well as other substance use compared to controls matched on important sociodemographic variables (age, gender, and educational attainment). The goal of the present study was to systematically replicate and extend this association between LA and smoking status by comparing those meeting criteria for current-, former-, and never-smoking status.

AIMS AND METHODS

In total, 984 individuals (N = 984) that endorsed current cigarette smoking (past 30-day use; n = 361), former-smoking (no past 30-day use, >100 cigarettes lifetime; n = 317), and never-smoking (no past 30-day use, <100 cigarettes lifetime; n = 306) were recruited using standard crowdsourcing methods and completed measures of LA (50-50 gambles) and delay discounting (DD) (monetary choice questionnaire), an important decision-making bias with an established relationship to cigarette-smoking status.

RESULTS

Lower LA was observed in those endorsing current smoking compared to former smoking (t[952] = -9.57, Bonferroni corrected p < .0001), and never-smoking (t[952] = -3.99, Bonferroni corrected p = .0002). LA was also greater in former- compared to the never-smoking (t[952] = -5.26, Bonferroni corrected p < .0001). This pattern did not change when accounting for DD and sociodemographics. DD results replicated prior findings.

CONCLUSIONS

The results support LA as a decision-making bias related to the risk of cigarette smoking and other substance use. Further research is needed to understand the causal contributions of LA and DD and their potential intersections.

IMPLICATIONS

Low LA is a risk factor for cigarette smoking. This study reports higher LA among individuals that endorsed never-smoking and former-smoking status in comparison to those endorsing current cigarette smoking. LA may influence or be influenced by a change in smoking status.
