The PsychCentral website (https://psychcentral.com) offers a wide selection of online self-assessments, most of which it says are rooted in scientific research. These assessments can be used to learn more about many of the presenting problems discussed throughout this book. While they may provide you with insights into yourself, in rare instances students become upset with what these online tests tell them. If you have concerns, consult your professor, or seek professional help.
