Adding an underline to the word “Abstract” in \abstract?

Question

To meet the requirements of the university, I need to be able to underline the word Abstract in my dissertation? Can anyone provide me with some guidance on how best to do this using the apa6 class? Thanks in advance for your help.

Answer 1

You can use the etoolbox package to patch the \maketitle command responsible for typesetting the abstract:

\documentclass[doc]{apa6}
\usepackage{etoolbox}

\title{The Title}
\threeauthors{John and Jim}{Mary and Sue}{Nick}
\threeaffiliations{U of A}{U of B}{U of C}
\abstract{text}

\patchcmd{\maketitle}{\abstractname}{\underline{\abstractname}}{}{}

\begin{document}

\maketitle

\end{document}

Answer 2

You can just do

\renewcommand{\abstractname}{\underline{Abstract}}

This may not work well with other language settings (that is, an automated adaptation), but it doesn't require any packages.
