psychometric properties of the farsi version of eyberg child behavior inventory (fecbi) in iranian population

Objective: eyberg child behavior inventory (ecbi) is one of the most frequently used tools for measuring behavioral problems; however, no research has been done to evaluate its psychometric properties in iran.method: the present study sought for exploring the factor structure and psychometric properties of the fecbi in an iranian sample. a total of 495 mothers (mean age = 33.83 years; sd = 4.78) who reported behavioral problems in their children aged 3 to 12 years (mean age = 6.36 years; sd = 2.66) were selected via convenience sampling in 20182019. the psychometric properties of fecbi, including reliability (cronbach’s alpha) and validity (exploratory and confirmatory factor analysis, and convergent validity) were assessed using spss version 25 and lisrel 8.80.results: by performing efa on the first sample part (n = 360), the examination of scree plot supported a 3factor or 4factor solution, and pattern matrix resulted in a 3factor structure. the factors were called as “behavioral problems related to oppositional defiant”, “behavioral problems related to inattentive”, and “behavioral problems related to conduct”, according to their content and the research. cfa was performed on the second part of the sample (n = 135) to test the fitness of the 3factor solution. according to cfi (0.91), nfi (0.91), nnfi (0.90), ifi (0.91), pnfi (0.77), gfi (0.75) agfi (0.70), pgfi (0.62) and chisquare (540.31) indexes, the model had acceptable fitness. cronbach's alpha was employed to measure the internal consistency and it revealed to be at a good to excellent level (behavioral problems related to oppositional defiant = 0.88; behavioral problems related to inattentive = 0.84; behavioral problems related to conduct = 0.74). the 3factors subscales were associated with total difficulties, internalizing and externalizing sdq, indicating the good convergent validity of fecbi.conclusion: the fecbi has good psychometric properties in iran and can be employed as a useful instrument for measuring children's behavioral problems.
