The self-help genre began in 1859 with the publication of Samuel Smiles’s book, Self-Help. Inspiring the title of the genre, Smiles’s book details the virtues of self-reliance. It was not until the late 20th century that the self-help genre transformed into the cultural phenomenon it is today. Self-help books are defined as texts that provide readers with instruction on how to solve problems in their personal lives, and originated as informal guides to behavior. In classical Rome, writers like Cicero and Ovid produced texts that sought to instruct readers on various subjects. It was not until the 1960s, however, that self-help books entered popular culture.

Self-help books often incorporate popular psychology on topics such as romance. However, books within the self-help genre differ from traditional psychology books. The latter maintain a professional, objective voice, while self-help books typically use the first-person point of view and include personal anecdotes. In addition to their dedication to instruction, self-help books aim to offer readers self-insight that can lead to empowerment.  

Levine and Heller’s Attached embodies the characteristics of the self-help genre. The authors explicitly state their intention to educate readers on attachment theory and to provide practical resources to help readers apply attachment theory to their own lives and improve their experience in relationships.
