Telephone counselling research study

Hi everyone,
I am a Psychology Undergraduate student at the University of Roehampton, researching how receiving telephone counselling with a withheld number may impact the quality of therapeutic alliance on client's experience.
Have you received or are receiving telephone counselling with a withheld number? Does it create a contact barrier that stops you from reaching out to your therapist? Does it make your therapist less trustworthy and unreliable? Regardless, it would be great to hear from you if you are interested in sharing your thoughts and experiences.
I am looking for a minimum of 10 anonymous people who are **18 and above**, have had at least **one telephone counselling session** and would be willing to share **their experiences **in an online survey. If you are interested in taking part in this research, please click the link that has been provided to start the survey.
Thank you very much.
