I intend to work on the topic: "Unifying Model of Sexual Identity Development". The closest thing I could find on wikipedia was the Cass Identity model, but the Unifying Model of Sexual Identity Development is the most current model for sexual identity development because it covers a spectrum of identity development, unlike Cass.

FEEDBACK Does this mean you're adding to the Models of Sexual Identity subsection? https://en.wikipedia.org/wiki/Sexual_identity#Development

That works. Looking forward to seeing this addition.

Unifying Model of Sexual Identity Development

The Unifying Model of Sexual Identity Development, developed by Frank Dillon, Roger Worthington, and Bonnie Moradi, draws from previous identity models such as Homosexual Identity Development Model (Cass, 1979), Life Span Model (D’Augelli, 1994), and Model of Gay and Lesbian Identity Development (Fassinger & Miller, 1997) to create a model that can be applied to varying sexual identities (Patton et al, 2016). Dillon et al. (2011) described sexual identity development as dependent on three factors: biopsychosocial processes, individual identity, and social identity. The model uses five non-linear statuses that can be used to demonstrate individual and social identity.

Five Statuses

Compulsory heterosexuality

This status consists of an individual’s commitment to heterosexuality within the lens of the culture that the individual is a part of.

Active Exploration

This status consists of an intentional exploration of an individual’s sexual identity both cognitively and behaviorally.

Diffusion

This status consists of the lack of intentional exploration or commitment to an individual’s sexual identity.

Deepening and commitment to status

This status consists of an individual committing to a sexual identity that involves being able to better identify things such as one’s sexual orientation or preferences.

Synthesis

This status consists of an individual achieving a sexual self-concept.

Research supporting the Unifying Model of Sexual Identity Development:

This model was developed by “teams of scholars working in various combinations over time to collaborate and develop ideas to provide empirical support for a new theoretical model” (Patton et al, 2016).
