THE SCALE OF READINESS FOR SELF-IMPROVEMENT: AN ANALYSIS OF ITS INTERNAL CONSISTENCY, THEORETICAL VALIDITY AND RELIABILITY
Journal Title: Acta Neuropsychologica - Year 2014, Vol 12, Issue 1
Abstract
This article presents a proposed instrument to measure readiness for self-improvement understood as an individual’s intention to improve their own characteristics, skills, health, or well-being. Four studies were conducted to check the reliability and validity of the SRSI scale. In order to check the structure of the tested construct of readiness for self-improvement the explanatory factor analysis and the confirmatory factor analysis were applied to wo separate studies. Then, Cronbach’s Alpha was performed to ascertain reliability of the SRSI scale. Next, two other studies were conducted to ascertain SRSI theoreti cal validity. NEO-FII (Costa, McCrae 1987 adapted by Zawadzki, Strelau, Szczepański, Śliwińska 1998) and life sa tisfaction scale (Czapiński, Panek 2009) were used to measure theoretical validity of the SRSI scale.The results of four independent tests are presented here, indicating that the Scale of Readiness for Self-Improvement (SRSI) has not only internal consistency and good reliability (tests 1 and 2), but also theoretical validity (tests 3 and 4). The results of test 3 showed that the SRSI gives results that correlate with those of the NEO-FFI; test 4 showed similar correlations between the SRSI and the Measure of Total Life Satisfaction.The SRSI presented here, which identifies the individual’s attitude towards self-improvement, can be a useful instrument in the context of anticipating changes in the behavior of people in health and illness. Moreover, this scale can make it possible to make a preliminary evaluation of one of the individual’s personal resources, which is readiness for self-improvement.
