It is said that working on forgiveness in psychological counseling will significantly benefit the individual, taking into account the good consequences of forgiving on the individual. This study aimed to develop a measurement tool for determining self-efficacy to work on forgiveness in counseling (SSWOFIC). The most commonly regarded forgiveness process model, Enright's Forgiveness Process Model, served as the foundation for the creation of this measurement tool. 285 counselors provided information for the Exploratory Factor Analysis (EFA) and 258 counselors provided information for the Confirmatory Factor Analysis (CFA). For the content validity of the scale, eight specialists were contacted. EFA revealed a single factor structure with 41 items that accounted for 61.7% of the overall variation. It was found that all of the SSWOFIC's items were discriminative and had a high level of factor loading value in the pertinent factor. To ascertain if the structure identified by EFA was confirmed or not, CFA was carried out. The one-factor structure was confirmed, as evidenced by the resulting model's fit indices. The computed Cronbach's Alpha and McDonald's Omega reliability coefficients were 0.99, and the Split-Half method's results for the Guttman and Spearman-Brown coefficients were 0.96. The SSWOFIC results demonstrated the validity and reliability of the scale, which consists of a single component and 41 items. The established scale will make it possible to conduct studies to ascertain the level of self-efficacy of psychological counselors with regard to this matter and to examine this feature in terms of other variables.
