The aim of this study was to develop ameasurement tool for determining students’ effective reading self-efficacy perceptions. The study group of the research was composed of a total of 677 secondary school students (345 boys and 332 girls) receiving education at schools located in central districts of theprovince of Bursa during the 2016-2017 academic year, plus 10 domain experts.The students were selected by the random sampling method from 5 different secondary schools.At the scale development stage, 56 action items were created, and after the item-total correlation values of these items had been calculated, items with low values were removed from the scale, and exploratory and confirmatory factor analyses were performed by using the remaining 41 item data.After items had been removed according to the results of these analyses, the remaining 21 items were presented in a four-factor structure.The eigenvalues of the 4 factors, which explained 56.83% of the cumulative variance, were determined to be 4.180 for the first factor, 2.512 for the second factor, 4.096 for the third factor and 1.153 for the fourthfactor, respectively.Regarding internal consistency of the scale as a whole, a Cronbach’s alpha value of ⍺=0.876 was calculated.According to the results of the confirmatory factor analysis (RMSEA=0.070; SRMR=0.073;NNFI= 0.91; CFI =0.94), it was found that the model fit was at an acceptable level for the fit index values and also that the chi-square value (477.07; p<0.05) was significant, indicating that the data had the characteristic of normal distribution.Following the analysis performed for the scale validity, it was determined that there was a significant relationship between the application results (r=0.82; p<0.01).This situation reveals that the scale has criterion validity.The obtained findings are such as to support the idea that the present effective reading scale has validity and reliability.
