Use DoNotPay To Search for All Types of Psychological Studies

Psychological studies are the ultimate method that scientists use to discover more information about the intricacies of human behavior and new treatments for various mental health issues. They can involve various types of research, from medical surveys and questionnaires to full-blown clinical trials organized in four phases.

If you’re thinking about participating in a psychological study, finding the right trial or survey will be easy with DoNotPay’s search platform for clinical studies of all kinds. 

Types of Psychological Studies Based on Methodology 

Psychological studies can be classified based on various criteria. We can divide studies based on the field of psychology they belong to or issues they focus on. When it comes to the method used in different psychological studies, researchers usually differentiate between five types of psychological studies:

  • Descriptive studies—Use observation to give an account of a certain phenomenon (for example, a psychologist wants to research the quality of available mental health institutions)
  • Correlational studies—Statistical analysis that shows how two phenomenons are connected (for example, the relationship between alcoholism and depression)
  • Experiments—Most precise studies, focused on the causes and effects (for example, researching whether music improves memory skills)
  • Naturalistic observations—Observational studies in a natural setting without influencing or controlling the participants
  • Self-reports—Tests, interviews, questionnaires

Since psychology and psychotherapy increasingly rely on various treatment options, including medication, psychological studies may involve full-blown clinical trials sponsored by various pharmaceutical companies or institutes.

Phases of Clinical Trials in Psychology

If you’re considering participation in clinical trials that deal with mental health issues and research new medications or other treatment options, you should familiarize yourself with the phases every clinical trial has to go through. 

Each stage of research comes with unique targets and risk levels. It is important to find out which trial phase you would be joining. 



Test Group Size


  • Priority: safety 
  • Usually the shortest phase
  • Answers questions about the administration of the new treatment, absorption in the human body, possible side effects

Less than 100


  • Priority: efficacy
  • Usually targets the groups suffering from a specific condition
  • Doesn’t require participants to stay in a facility in most cases

Several thousand people

Questions To Ask Your Recruiter 

When you contact the organizers of the study you’re interested in, the recruiting staff will provide all the information relevant for making your final decision about participation. In clinical trials, this process is called informed consent.

While it’s the recruiters’ job to explain every step of the process and associated risks, you can prepare a list of questions important to you. Some of the concerns you might want to address include:

  • What activities will my participation involve, and how much time will the study take?
  • How will this study help other people or me in the future?
  • What are the odds I will experience some negative side effects?
  • Could my condition get worse during the study? Will I receive appropriate care for free in that case?
  • What do I have to do at the end of the study?
  • How can I stop participating if I don’t feel comfortable anymore?
  • Will I be paid for participation and how?
  • How much time do I have before making the final decision?
