The purpose of this study is to adapt the Berkeley Parenting Self-Efficacy Scale Revised (BPSE-R) to Turkish. The scale is composed of two subscales, parental strategies and child outcomes, and includes 18 items. In the process of adapting the scale and examining its reliability and validity, 354 mothers of preschool children were selected through convenience sampling. After translation-and back translation procedures, the BPSE-R was evaluated by field experts, and the scale items were found to be consistent. Confirmatory factor analysis showed that the scale has a two-factor structure similar to the original scale. The fit indices obtained for this two-factor structure were found to be at a good level. The total score Cronbach's alpha internal consistency coefficient was calculated as 0.91, and the test-retest reliability coefficient was calculated as 0.67. Findings demonstrated that the Turkish version of the BPSE-R has adequate psychometric characteristics and can be used in determining the self-efficacy of parents in Turkey with preschool-aged children. The short duration in which the BPSE-R can be applied and its high reliability make it convenient for use in research.
