Abstract: | IntroductionSocial robots are robots capable of a peer-to-peer communication with humans. Nomura, Kanda, and Suzuki (2004) developed the Negative Attitude towards Robots Scale (NARS) to measure the attitudes towards robots. NARS proved to be a useful tool to study human-robot interaction.ObjectiveTo assess the psychometric properties of the Portuguese version of the NARS (PNARS).Method and resultsFour studies were conducted. In study 1 (n = 300), a principal component analysis showed that PNARS comprised two components: the negative attitudes towards robots with human traits (NARHT) and towards interaction with robots (NATIR). In study 2 (n = 536), a confirmatory factorial analysis was conducted. Results confirmed the two-factor solution of PNARS obtained in study 1. Study 3 (n = 107) tested the nomological validity of PNARS and showed that PNARS, NARHT and NATIR correlated with attitudes towards technology. Study 4 (n = 59) tested the predictive validity of PNARS and showed that scores on NARHT and NATIR predicted the future intention to work with a social robot and its affective and cognitive antecedents.ConclusionGlobally, results indicate that PNARS is a reliable instrument to use in human-robot interaction studies. |
