Abstract
The aim of the study is to validate the Multidimensional Attitudes Scale Toward Persons With Disabilities (MAS), applied to visual disabilities, in a sample of about 300 upper-secondary school students from 18 classes in 3 schools in the province of Trento Italy. An additional treatment group will be added to the original scale; a randomly chosen group of students will be asked to image the vignette in the study from their own perspective. Several covariates will be used: the Implicit Association Test applied to visual disability (Greenwald, Nosek and Banaji, 2003), the Attitudes Toward Disabled Persons scales 15 items shortened scale, applied to visual disability (Yuker 1970), and several demographics variables (gender, parental education, language spoken at home, age, indicators of contact with persons with visual disability).

Experimental Details

Interventions

Intervention(s)
The study will implement the MAS scale in Findler, Vilchinsky and Werner (2007). Students are asked to imagine a given social situation (vignette) from the perspective of another person (the gender is randomized).
This person is placed in an unexpected social situation which implies interacting with a person with a visual disability.

In contrast to Findler, Vilchinsky and Werner (2007), we do not randomize the gender of the person with a visual disability and instead use generic terms. In addition, we add another treatment group that requires students to imagine the situation from their own perspective.

Primary Outcomes

Primary Outcomes (end points)
Scores on each dimension of the MAS scale
Primary Outcomes (explanation)
The outcomes will be computed following Findler, Vilchinsky and Werner (2007). However, if the 3 factors detected in Findler, Vilchinsky and Werner (2007) are not confirmed in our study, we will compute the primary outcomes based on the detected factor structure.

Experimental Design

Experimental Design
Students will be randomly assigned to 3 groups:
- group 1: asked to imagine and fill the MAS scale from the perspective of a fictitious girl
- group 2: asked to imagine and fill the MAS scale from the perspective of a fictitious boy
- group 3: asked to imagine and fill the MAS scale from their own perspective
