For decades, the Big 5 model of personality has dominated as one of the most popular and widely used models of personality. The current article reviews the development and prevalence of the Big 5 model and explores the position of other personality variables not (or not fully) encompassed by this model, to see what lies ‘beyond the Big 5’. We start by comparing the Big 5 to the alternative six-factor HEXACO model, the Supernumerary Personality Traits, and a psychobiological model of personality. We then discuss the Dark Tetrad traits, self-defeating interpersonal styles, and trait emotional intelligence as examples of narrower personality traits which predict outcomes over and above the Big 5. Comparisons between these different personality models and the extent to which other personality traits can predict different psychological outcomes will be used to address the discussion of whether the Big 5 is a sufficient measure of personality, or whether other personality variables need to be also considered for a more comprehensive model of personality. Areas of consideration for researchers investigating Big 5 personality will also be discussed.
