Adaptation of the Family Functioning Test: Psychometric properties in high school students

Family is considered as a fundamental point for the development of people, where affection and security are found. The objective of this study was to analyze the evidence of validity and reliability of the Family Functionality Test in high school students. 625 students from 11 to 18 years of age participated (MA=14.52, SD=1.253, 60.8% male) and were students from first-fifth year of secondary level education. Construct validity was evidenced by confirmatory factor analysis showing optimal fit values X2/gl =3.84, CFI=0.943, TLI=0.932, SRMR=0.0342, RMSEA=0.0675. Internal consistency reliability obtained a Cronbach's Alpha of 0.915 and Omega of McDonald of 0.917 for the entire test. The results provide psychometric evidence, so the conclusion is that the family functioning test contains valid elements to be applied in secondary students.
