The purpose of the study is to explore the ethical context of informed consent in psychotherapy practiced by clinical psychologists, reflecting on the current situation, and offering suggestions and potential courses of action for improvements. Seven experienced clinical psychologists were invited to participate in both focus group interview and one-on-one intensive interview. Grounded theory was used to analyze the collected data. The results of the study revealed that the reasons for the participants not to practice informed consent include: institutional factors, assumption that the information was already known to the clients, not necessary to tell everything (telling by condition), only general information given, therapist's resistance, difficult to provide information, and unfamiliar with the differences of ethics code; Participants’ ethical reflections include: insufficient attention to the clients' rights and interests, the influence of the practice field, the impact on treatment, self-protection by therapists, and the therapist’s own factors; Recommended actions and changes include: enhancing the presentation of information and verbal explanations, emphasizing the sharing of professional information, personal development of therapists, adopting higher ethical standards. According to the results and findings, related issues are discussed, and the study offers suggestions for clinical practices, amendments to the ethics code, planning for ethics education, and future research.
