The Reported and Intended Behaviour Scale (RIBS) was developed in the UK to measure mental health-related behavior. The current study aimed to evaluate the applicability, and reliability of a Japanese version of the RIBS (RIBS-J) in a Japanese context, and further examine the construct validity of the RIBS-J.
The sample included 224 undergraduate and postgraduate students at a Japanese university. Cronbach's alpha was used to assess internal consistency. Pearson's correlation coefficient was used to examine the divergent validity between the RIBS-J and the Mental Health Knowledge Schedule and the convergent validity between the second subscale of the RIBS-J and Japanese version of the Social Distance Scale. Confirmatory factor analysis assessed the goodness of model fit of the RIBS-J. We also examined test–retest reliability with another undergraduate sample (n = 29).
Most items exhibited no floor/ceiling effect. High internal consistency (α = 0.83) was reported. The second subscale of the RIBS-J, measuring intended behavior, correlated with the Mental Health Knowledge Schedule (r = 0.33, P < 0.001) and the Japanese version of the Social Distance Scale (r = −0.60, P < 0.001). In addition, confirmatory factor analysis found good model fit for the RIBS-J (χ2 = 41.001, d.f. = 19, P = 0.002, goodness-of-fit index = 0.956, adjusted goodness-of-fit index = 0.916, comparative fit index = 0.955, root mean square error of approximation = 0.072). Overall test–retest reliability (ρc) was 0.71.
The RIBS-J is an appropriate and psychometrically robust measure of behavior towards individuals with mental health problems in Japan. Further studies using a community sample could assess the generalizability of our findings.
