Hi... First of all what is the purpose or your query?
1. Are you a Recruiter?
In that case, there are ample background verification firms that conduct such information checks with Candidates consent before finalizing a key position.
2. Are you a Fellow Professional who wants to run a check on your rival?
In that case, it is not only unethical but a criminal offense to stalk someone or verify their credentials without their consent, without a legal reason.
3. Are you a Patient?
In that case, you need to avoid getting into such issues and find a professional that suits your standards.
Psychologist's Credentials can be easily verified by running an online check and contacting their batchmates, colleagues, professors, etc.
A full-time Masters Degree is required to practice in India. They shall also hold a Bachelors Degree in Psychology and MPhil/ Phd Degree in Psychology as an additional higher qualification.
But Therapeutic competence depends on years of experience conducting long-term therapies and working intensively on a particular set of population.
Remember, Psychology is a Science -- 'Behavioral Science', but Counselling is an 'Art'.
So no-one can claim that they do it better than others because they hold a particular Degree.
But yes, working as a Psychologist requires minimum 5 years of education (Bachelors and Masters or an Integrated Programme) and 2-3 Years of Work Experience is a bare minimum to acquire the skill-set that's not taught in colleges/universities.
Be rational and avoid spending too much time upon things that do not directly impact you or your long-term goals, desires, and outcomes.
Next Steps
To consult a Psychologist, use a verified platform or consult a renowned professional.
You can also visit a Renowned Hospital/ Institute to avoid individually verifying a professional.
