Challenging Life Events Indications Scale: Validity and Reliability

Abstract

The main purpose of the current study was to develop a valid and a reliable measurement tool, Challenging Life Events Indications Scale (CLEIS), for the measurement of adults' reactions to challenging life events. The study was carried out with four different samples. The data were analyzed using exploratory and confirmatory factor, and ROC analyses via IBM SPSS and SPSS AMOS 24®. The factor loadings and corrected item-total correlations were found to be above the acceptable level, and the variance explained was 62.95%. The scale was observed to have a three-factor structure with an eigenvalue greater than 1, and fit indices of the relevant structure were at acceptable levels. ROC analysis results showed that the cut-off score of CLEIS was 78.5 for people who needed psychological support after a challenging life event, the sensitivity of the scale was for marking those who displayed indications of challenging life events with a likelihood of 0.527, and the specificity value was for identifying people who displayed indications of challenging life events in real situations with a likelihood of 0.050. The criterion validity of the scale was examined through the Perceived Stress Scale, and the results produced a correlation of .72 between CLEIS and perceived stress, and .46 between perceived coping and CLEIS. Overall Cronbach's alpha was found to be .96. The scale was found to be a valid and a reliable tool. The findings were discussed within the related literature and suggestions were made accordingly.
