This research dossier represents the completed research works towards the fulfilment of the Practitioner Doctorate in Counselling and Psychotherapeutic Psychology (PsychD). It offers an overview of my research journey followed by a literature review, and two qualitative studies: one Thematic Analysis (TA) and one Interpretative Phenomenological Analysis (IPA). The literature review explored the role of the therapeutic alliance when working with children and adolescents. The first qualitative research study explored therapist's perspectives of how parents impact the therapeutic alliance when working with children and employed a TA methodology. The second qualitative research study analysed parents' experiences of their child accessing psychological therapy and utilised an IPA methodology.
