Abstract
BackgroundInvesting in financial markets is promoted and protected by the government as an essential economic activity, but can turn into a gambling addiction problem. Until now, few scales have widely been used to identify gambling addicts in financial markets. This study aimed to develop a self-rating scale to distinguish them. In addition, the reliability and validity of the stock addiction inventory (SAI) were demonstrated.MethodsA set of questionnaires, including the SAI, south oaks gambling screen (SOGS), and DSM-5 diagnostic criteria, for gambling disorder was completed by 1005 participants. Factor analysis, internal consistency testing, t tests, analysis of variance, and partial correlation analysis were conducted to verify the reliability and validity of SAI.ResultsThe factor analysis results showed the final SAI consisting of two factors and nine items. The internal consistency and concurrent validity of SAI were verified. The Cronbach’s α for the total scale was 0.892, and the SAI and its factors were significantly correlated with SOGS.ConclusionsThis study developed a specific scale for financial market investments or trading; this scale proved to be reliable and valid. Our scale expands the understanding of gambling addiction in financial markets and provides a diagnostic reference.

Summary
Investing in financial markets is promoted and protected by the government as an essential economic activity, but can turn into a gambling addiction problem. Gambling addiction is characterized by recurrent and progressive maladaptive patterns of gambling behaviors, followed by a significant impairment in financial and psychosocial areas [1] It was previously classified as one of the impulse control disorders, but since the publication of the fifth edition of the diagnostic and statistical manual of mental disorders (DSM-5), it has been included in the substance-related and addictive disorders [2–4]. These institutions mainly focused on playing casinos or lotteries, betting on sports or online, and betting on horse, bicycle, or motorboat racing [6, 7] They reported that some financial market investors asked for help from the public services for gambling addiction, but whether investing in financial markets is gambling was described as “under-discussion.”.
