Summary
Romantic partners are crucial for transgender and/or nonbinary (TNB) people's identity support. The new Transgender/Nonbinary Identity Support from Partners Scale (TISPS) reliably measures this vital relationship support.
Area of Science:
- Psychology
- Sociology
- Gender Studies
Background:
- Transgender and/or nonbinary (TNB) individuals frequently identify romantic partners as a primary source of social support for their identity.
- Existing measures may not adequately capture the nuances of support within romantic relationships for TNB individuals.
- There is a recognized need for validated instruments to quantify TNB identity support provided by romantic partners.
Purpose of the Study:
- To develop and validate a multidimensional scale assessing TNB identity support from romantic partners.
- To evaluate the psychometric properties of the new scale, including reliability and validity.
- To identify specific subtypes of support TNB individuals receive from their partners.
Main Methods:
- A multi-phase process involving item generation from qualitative research and cognitive interviews.
- Exploratory and confirmatory factor analyses were conducted on data from 321 TNB individuals (piloting) and 299 TNB young adults (validation).
- Psychometric properties, including reliability and measurement invariance, were assessed using survey and weekly diary data.
Main Results:
- The 19-item Transgender/Nonbinary Identity Support from Partners Scale (TISPS) was developed and demonstrated reliability and validity.
- The TISPS measures overall TNB identity support and five distinct subtypes: Facilitation, Identity Validation, Celebration, Allyship, and Understanding.
- The scale showed strong psychometric properties at the between-relationships level, with a consistent factor structure and good reliability.
Conclusions:
- The TISPS is a psychometrically sound instrument for measuring TNB identity support within romantic relationships.
- This scale can be utilized in clinical practice, community settings, and future research.
- The TISPS will aid in understanding the role of partner support in the mental health and well-being of TNB individuals.

13.7K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

01:30Socioemotional Experience and Gender Development
256
Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

01:29Self-Discrepancy and Its Effects
271
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...
