In present study, "development tasks supporting scale" (DTSS) for fathers has been developed. Study group consists of 205 fathers with children between ages 3-6 attending pre-school education institutions. Validity and reliability tests have been conducted on the 36-item trial form of the scale. For the validity test, expert views, explanatory and confirmatory factor analysis, bottom and top 27% group discrimination and item total correlation coefficients have been calculated. At the end of explanatory factor analysis, a structure with 17 items and five dimensions has been obtained. Five dimensions explain 64.46% of the total variance. As a result of confirmatory factor analysis (CFA), it has been determined that compatibility statistics of scale are [RMSEA (0.03), RMR (0.07) and SRMR (0.05), GFI (0.93), AGFI (0.89), NNFI (0.98), CFI (0.98)] near perfection. Cronbach alpha value of the reliability of scale has been calculated as 0.84 and re-tests reliability as 0.86. (Contains 1 figure and 1 table.)
