APA style referencing

Question

I am writing my thesis in LaTeX (to be more specific in Overleaf). For this, I had to refer to articles and do this using APA style. However, I could not find the right way of referencing. I already have this settings, that I found on the internet, but still it does not refer to articles the way it should be.

\usepackage{apacite}
\bibliographystyle{apacite}
\bibliography{references}

\documentclass[a4paper,10pt,twoside]{report}. 

This is an example of the text:

Besides this, job resources could buffer the negative impact of high job demands. \cite{bakker2007state}. 

and the bib:

@article{bakker2007state,
  title={The job demands-resources model: State of the art},
  author={Bakker, Arnold B and Demerouti, Evangelia},
  journal={Journal of managerial psychology},
  volume={22},
  number={3},
  pages={309--328},
  year={2007},
  publisher={Emerald Group Publishing Limited}
}

The in-text references only include the authors, not the year of publication. How should I do this?

And I also have another question. In a sentence like "Research performed by Petrou (2012) shows ...", how should I refer to this article, because when I use \cite{...}, everything including the authors name becomes between brackets.

You would really help me and my thesis!

One of the most well-known concepts of increasing social wellbeing is the concept of job crafting, which is defined as an action in which individuals make physical and cognitive changes in the tasks or relational boundaries of their work \cite{wrzesniewski2001}. Employees who take these actions, may increase their work engagement, job satisfaction, resilience and thriving \cite{berg2008}. This process can be described as a bottom-up process, the employee takes the initiative to redesign the job instead of the employer.

Answer 1

The issue you are facing can be reproduced in the following small example

\documentclass[a4paper,10pt,twoside]{report}
\usepackage{apacite}
\bibliographystyle{apacite}
\usepackage{hyperref}

%\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{bakker2007state,
  title={The job demands-resources model: State of the art},
  author={Bakker, Arnold B and Demerouti, Evangelia},
  journal={Journal of managerial psychology},
  volume={22},
  number={3},
  pages={309--328},
  year={2007},
  publisher={Emerald Group Publishing Limited}
}
\end{filecontents}


\begin{document}
Besides this, job resources could buffer the negative impact of high job demands. \cite{bakker2007state}. 
\bibliography{\jobname}
\end{document}

The example throws several errors during complitaion (never ignore errors!) and in the resulting output the year is missing in the citation

This is due to a conflict between apacite and hyperref. The apacite documentation explains (§8.2 hyperref, backref, and url, pp. 47-48)

These redefinitions have caused severe incompatibility problems between apacite and hyperref in the past. These incompatibility problems have been solved and apacite is compatible with hyperref, provided that apacite is loaded after hyperref.

So you should load apacite after hyperref. (This is contrary what is normally recommended, since hyperref should generally be the last package you load.)

compiles without errors and produces
