Wise Intervention LGB-TNB
BehavioralThe intervention will be designed to reduce aggressive behaviors based on sexual orientation and gender identity and to promote prosocial behaviors toward these individuals. This intervention will include three components: (1) reading scientific studies about people's ability to change. In addition, they will read other studies about how thoughts and emotions influence behavior through brain pathways, and that these pathways can be modified under certain circumstances; (2) reading testimonials that support the idea that people can change. These testimonials include accounts of people who were victims or perpetrators based on sexual orientation and gender identity, including important components of empathy and prosocial behaviors toward the victims. To give credibility to the intervention, they will be informed that these stories were written by other young people who previously participated; and (3) self-persuasion exercises that involve an active commitment to change.
Values alignment wise intervention
BehavioralThis intervention will be based on the same strategies as the experimental intervention, but it will not address aspects related to prosocial behaviors or aggression toward LGB-TNB individuals; instead, it will be applied to improve adolescents' eating habits.

Trial outcomes
Primary outcomes
1
Change from baseline in aggression scores toward LGB-TNB individuals, assessed using an adaptation of the Spanish version (Orue et al., 2018) of the Homophobic Bullying Scale (Prati, 2012).
It consists of seven items that ask frequency with wich participants have engaged in specific aggressive behavior toward LGB-TNB individuals. Five response categories are provided using a Likert-type response scale, ranging from 1 (never) to 5 (daily).
Time frame
Assessments were conducted at baseline and at 3, 6, and 9 months.2
Change from baseline in online aggression scores toward LGB-TNB individuals, assessed using the Technology-Facilitated Gender- and Sexuality-Based violence (TFGSV; Martínez-Bacaicoa et al., 2023).
It consists of eight items that ask frequency with wich participants have engaged in online aggressive behavior toward LGB-TNB individuals. Five response categories are provided using a Likert-type response scale, ranging from 1 (never) to 5 (daily).
Time frame
Assessments were conducted at baseline and at 3, 6, and 9 months.3
Change from baseline in prosocial behavior scores toward LGB-TNB individuals through an ad hoc measure.
It consists of one item in which participants were asked to select all the behaviors they engaged in after witnessing an aggression.
Time frame
Assessments were conducted at baseline and at 3, 6, and 9 months.4
Change from baseline in bystander intention scores when witnessing aggressive behavior toward LGB-TNB individuals.
This measure evaluate bystander intentions in response to LGB-TNB aggressions, through different scenarios. After reading the scenarios, participants answered five items that evaluated possible courses of action to take in response to the aggression.
Time frame
Assessments were conducted at baseline, immediately after the intervention, and at 3, 6, and 9 months.Secondary outcomes
1
Change from baseline in moral disengagement scores, assessed using the mechanisms of moral disengagement described by Bandura (2016) and based on studies with similar characteristics (Martínez-Bacaicoa et al., 2024).
It consists of eight items representing the eight mechanisms that allow participants to morally disengage. Five response categories are provided using a Likert-type response scale, ranging from 1 (strongly disagree) to 5 (strongly agree).
Time frame
Assessments were conducted at baseline and at 3, 6, and 9 months.2
Change from baseline in justice sensitivity scores, assessed using the Justice Sensitivity Inventory (Schmitt et al., 2010).
It consists of 10 items that assess sensitivity to unjust situations. Five response categories are provided using a Likert-type response scale, ranging from 1 (strongly disagree) to 5 (strongly agree).
Time frame
Assessments were conducted at baseline and at 3, 6, and 9 months.3
Change from baseline in behaviors supporting LGB-TNB individuals, assessed using the LGBT-Affirming Behavior questionnaire (Poteat, 2015).
It consists of five items that assess supportive behaviors toward LGB-TNB individuals. Five response categories are provided using a Likert-type response scale, ranging from 1 (0 times) to 5 (7 or more times).
Time frame
Assessments were conducted at baseline and at 3, 6, and 9 months.4
Change from baseline in microaggression scores toward LGB-TNB individuals, assessed using the Sexual Orientation Microaggression Scale (SOMS-P; Botor & Tuliao, 2025) and the Gender Identity Microaggression Scale (GIMS-P; Botor & Tuliao, 2025).
A total of 25 items are used to assess microaggressions toward LGB-TNB individuals. Specifically, 20 items assess microaggressions toward LGB individuals and 5 items assess microaggressions toward TNB individuals. Five response categories are provided using a Likert-type response scale, ranging from 1 (never) to 5 (almost every week).
Time frame
Assessments were conducted at baseline and at 3, 6, and 9 months.Sponsors and contacts
