Why this paper matters

This paper was written in 2019 by a clinician inside the UK's GIDS at Tavistock — at the time the world's largest gender identity clinic for children and adolescents, and subsequently subject to the critical Cass Review (2024). It is notable because the author was working within the system and arguing, from the inside, that the field was moving too fast and needed a more thorough, exploratory framework.

The paper offers a theoretical model and a worked clinical example. It is not an outcomes study, but rather a practitioner-level framework paper — describing how exploratory therapy with gender-questioning youth can be conducted ethically without being either affirmative-by-default or reparative.

The problem: two bad poles

Spiliadis identifies two dominant approaches in the field that he considers inadequate on their own:

1. The gender affirmative model

This approach, initially developed in the USA, actively affirms the young person's stated gender identity and supports early social and medical transition on the basis of the young person's "privileged access" to their own gender experience. In practice, this often means:

Spiliadis does not describe this as malicious, but he challenges the assumption that speed equals compassion. The model does not adequately account for the complex, heterogeneous presentations increasingly seen in clinical practice.

2. Reparative / conversion approaches

At the other pole, some practitioners have historically attempted active therapeutic interventions designed to change the young person's gender identification — "therapy" aimed at making them accept their natal sex. This approach is explicitly condemned across the UK's healthcare establishment as unethical and harmful, and is covered by the Memorandum of Understanding (MoU) against conversion therapy signed by NHS England, UKCP, and others.

Spiliadis is clear: he is not proposing this. He notes that the MoU itself explicitly allows psychotherapy that helps people "explore therapeutic options to help them live more comfortably," as long as the clinician is not actively "guiding" toward a specific identification.

The Gender Exploratory Model (GEM)

GEM is framed as a systemic-developmental approach — grounded in family therapy and systemic practice, and attentive to the young person's developmental stage. Its core commitments:

Three domains of clinical action

Spiliadis borrows a framework (Lang, Little & Cronen, 1990) to describe how GEM operates in three domains:

The case of "Peter" — a detailed illustration

Spiliadis presents an anonymised case that illustrates GEM in practice. This is the most concrete and useful section of the paper for parents to understand what the model looks like on the ground.

Who Peter was at referral

Peter (referred as "Louise") was a 15-year-old male-bodied young person referred to GIDS by a school counsellor. Peter had socially transitioned — using a new name, wearing stereotypically feminine clothes, experimenting with make-up, having obtained a legal name change via deed poll. Peter's parents were fully supportive and had consented to the name change. Peter was certain he was trans, certain he wanted oestrogen and eventual surgery, and was frustrated to have to go through a lengthy assessment instead of being fast-tracked to medical treatment.

What the exploratory work uncovered

The assessment consisted of 11 sessions (8 family-based, 3 individual) over 12 months, followed by 7 individual sessions over a further 8 months — approximately 20 months in total.

How it ended

Shortly after his 17th birthday, Peter came to a session with his hair cut short and without make-up. He reported having had a first intimate experience with another male-bodied young person, which he described as an important developmental step. He spoke about wanting to explore a more fluid identity rather than a stereotypically female one, and asked to pause his referral for hormonal interventions. In the final session, he asked Spiliadis to use his birth name and he/him or they/them pronouns. A 6-month review was planned, and discharge was anticipated.

"When asked what enabled him to understand himself in a different way to how he initially presented to GIDS, Peter spoke about the invitation from the GIDS to explore the meaning of his multi-layered identities. He was able to share how his initial frustration around the staged approach of our interventions was gradually alleviated by him feeling understood and listened to in the consulting room."
