Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Attitudes Measured With the ATTID-Questionnaire
Time Frame: Change from baseline (T1) attitudes toward people with intellectual disability (ATTID-Questionnaire) at 3-4 month (T2) and 8-9 month (T3)
The ATTID-SF Questionnaire encompassing three core components. The affective component refers to emotional responses toward individuals with intellectual disabilities. The cognitive component encompasses beliefs, knowledge, and perceptions about this population. The behavioral component reflects self-reported actions. The short form comprises 35 items rated on a 5-point Likert scale (1 = strongly agree to 5 = strongly disagree), with higher scores indicating more negative attitudes. Items are grouped into five factors: (1) interaction, (2) sensitivity/tenderness, (3) discomfort, (4) knowledge about abilities, and (5) knowledge about causes of intellectual disabilities. Mean scores are calculated for each factor; however, due to the scale's factor structure, an overall score is not recommended. So the minimum mean score for each factor is 1, the maximum means score is 5.
