the effect of individuals’ personality traits on the perceived effort assessed by visual analogue scale: an experimental study

Background: this study aimed to examine the effect of individuals’ personality traits on the perceived effort.methods: this experimental study was conducted from october 2022 to december 2022 on 30 students using general health questionnaire (ghq-28), raven’s intelligence quotient (iq) test, visual analogue scale (vas), revised neuroticism, extraversion, openness to experience (neo) personality inventory, and jamar hand dynamometer (jhd).results: a significant positive correlation was found between the exerted force to the jhd (ef-jhd) and perceived effort rated on horizontal vas (pe-h/vas) and vertical vas (pe-v/vas) in the individuals with low levels of ‘neuroticism’. considering ‘extraversion’ and ‘agreeableness’ factors of the neo test, the correlation coefficient between ef-jhd, and pe-h/vas and pe-v/vas was higher in the individuals with medium levels compared to those with high levels. this relationship was reverse for the ‘openness to experience’ and ‘conscientiousness’ factors. the results demonstrated a significant strong positive correlation between pe-h/vas and pe-v/vas (r=0.97). multiple linear regression analysis revealed a moderate positive correlation between ef-jhd and pe-h/vas and between ef-jhd and pe-v/vas.conclusion: individuals’ personality traits are recommended to be considered in assessing the perceived effort by vas.
