Impact of amputation of the upper limb and prostheses on perceptions of competence, warmth, and functional abilities

This study investigated attitudes that young adults have toward individuals with amputation of the upper limb (AUL). Previous studies have found that people tend to feel sympathy toward these individuals, but they are also perceived as less competent in various situations. However, it is unclear if these perceptions are influenced by factors such as the cause of amputation, the gender of the amputee, whether they use a prosthesis or not, or the type of prosthesis.

The survey included 469 participants from a university in the Southeastern United States. Participants rated pictures of individuals with or without amputation, and with and without prostheses after reading a brief background scenario. Images were rated using a semantic differential for competence and warmth, and a scale of functional ability.

Factorial analysis of variances produced significant main effects indicating individuals with AULs who used prostheses were rated with higher competence and ability than individuals with AULs who did not use prostheses. Females were rated with lower competence and ability, and higher warmth regardless of AULs status. Higher ability ratings were obtained for individuals with advanced technology prostheses as compared to body-powered prostheses.

Our research shows that people generally hold positive attitudes toward individuals with AUL when they use prostheses. However, traditional stereotypes persist for those who do not. Negative biases toward women should be accounted for in disability stigma studies. The cause of amputation did not influence ratings. Prostheses that appear to be advanced technology positively influenced ratings of functional ability when compared to traditional body-powered types.
