Validity and Reliability of The Turkish Version of Fear of Cancer Recurrence Inventory
OBJECTIVE The aim of this study is to conduct the Turkish adaptation and to test the validity and reliability of the Turkish version of the "Fear of Cancer Recurrence Inventory (FCRI)". METHODS A total of 219 mixed-type cancer survivors with a mean age of 50.76 years participated in the study (79.9% women). I hey were asked to complete the Impact of Events Scale (IES) and Patient Health Questionnaire-Somatic, Anxiety, and Depressive Symptoms (PHQ-SADS) along with the translated version FCRI. RESULTS By exploratory factor analysis and oblique rotation, the number of factors of the original scale decreased from 7 to 5 and three of them have been renamed ("recurrence-related meta-cognitions", "emotion-focused coping strategies," and "quality of life"). The overall Cronbach's alpha coefficient of FCRI was 0.94 and the item-total correlations ranged between 0.37 and 0.75. With respect to concurrent validity, except for the "avoidance" subscale of IES, significant correlations (r=0.13-0.70; all P<0.01) were found between FCRI factors and the total scores and subscales of other measures, similar to those in the original scale. CONCLUSION The Turkish version of FCRI has satisfactory psychometric properties, and it is eligible for use in studies in Turkey.
