This study examined the moderating role of an illusion of control (IOC) in the differential contributions of forms of near-miss (NM) in youths intent to gamble in Nigeria (n = 60, mean age = 18.05, SD = 3.81) using a randomized group design. Data were obtained by means of the Gambling Episode (GE) stimulus material that varied NM into early-miss, late-miss, near-win and near-loss groups, and self-report measures of IOC and gambling intention. One-way analysis of variance (ANOVA) result showed that NM groups differed significantly on gambling intention. HAYES PROCESS macro moderation analysis results of NM categories as dummy variables showed that early miss had a non-significant negative effect on gambling intention, late miss had a significant positive effect on gambling intention, near win had a significant positive effect on gambling intention, IOC had a negative effect on gambling intention, and negatively moderated the effect of early win on gambling
