Reducing Transphobia Among Adolescents Through a Brief Video Intervention

Attitudes toward Transgender Men and Women (ATTMW; Billard, 2018) is a scale to measure transphobic attitudes. It is a 24-item scale consisting of two similar but non-identical 12-item subscales, one for transgender males (ATTM), and one for women (ATTW). In this study, the study team will assign only one of the two subscales, according to the condition that subjects as randomly assigned to: those viewing the transgender adolescent male will be assigned to the ATTM; those to the female, to the ATTW. The results of both subscales are compatible with each other and can be merged into a single ATMW score. Each of the items is a statement on which participants are asked to rate their agreement on a 7-point Likert-type scale: from 1 (strongly disagree) to 7 (strongly agree). Higher scores indicate greater anti-transgender prejudice, while lower scores indicate less prejudice.

The first 9 items are the same for the ATTM and AATW. Items 10-12 are unique for each of the two scales. These

This study will utilize a scale called feelings thermometer, modeled after Norton and Herek, 2013:

"Using a scale from zero to 100, please tell us your personal feelings toward each of the following groups of friends, teachers, or colleagues. As you do this task, think of an imaginary thermometer. The warmer or more favorable you feel toward the group, the higher the number you should give it. The colder or less favorable you feel, the lower the number. If you feel neither warm nor cold toward the group, rate it 50." To familiarize respondents with the response format, they will be first presented with thermometers for "Men in general" and "Women in general," with each respondent rating her or his own sex first. Next, they rate different gender groups (transgender males, transgender females). Higher ratings (maximum 100) indicate warmer, more favorable feelings toward the target whereas lower ratings (minimum 0) indicate colder, more negative feelings.

The DSS (Christensen, Jorm, Evans, & Groves, 2004) is a self-report instrument composed of two 9-item subscales. The first subscale measures the participants' own/ personal attitudes, and the second measures participants' beliefs about the attitudes of others ('Depression is sign of weakness' vs. 'Most people believe that depression is a sign of weakness'). The Personal subscale (DSS-Personal) will be used in this study. The DSS has a 5-point Likert scale ranging from strongly disagree (1) to strongly agree (5). The total score comprises the sum of its item scores, and a higher score indicates more stigma (worse outcome). The DSS-Personal subscale has shown adequate psychometric properties: 0.71 test-retest reliability, 0.76 internal consistency (Griffiths et al., 2004). In our earlier study (Amsalem and Martin, 2021), Cronbach's a was .83.

The General Help-Seeking Questionnaire (GHSQ) (Wilson, Deane, Marshall, & Dalley, 2008) was developed to measure help-seeking intentions from different sources (friend, parent, mental health professional, and others) and is divided into personal-emotional problems and suicidal thoughts (Ibrahim et al., 2019). The instrument consists of 10 items for each part, each rated on a 0 (extremely unlikely) to 7 (extremely likely)Likert scale. Higher scores on this scale indicate more help seeking (better outcome).
