Adaptation of Family Affluence Scale II into Turkish: A Validity and Reliability Study

This study aimed to test the validity and reliability of the "Family Affluence Scale II (FAS II)", in Turkish university students to determine socioeconomic status. The scale was developed in the project titled "Health Behavior in School-aged Children-HBSC" conducted by the World Health Organization in 1997. AThe scale was revised in 20012002 and the revised form was used in this study. Two-hundred forty students aged 1924, Awith 97 female (X-age=20.08, age =20.08, SD =0.94 year) and 143 male students (X-age=20.29, age =20.29, SD= 1.23 year) participated in the study. The scale consists of four questions asking about the number of cars owned by the family, whether there is a room for the child, the number of holiday trips with the family in the last year, and the number of computers owned by the family. Exploratory Factor Analysis computed for construct validity showed a single factor structure that explained 45.40% of the variance. The factor loadings ranged from 0.55 to 0.73. The analysis for concurrent validity revealed a significant positive correlation between FAS II and SES scale (r = 0.73, p <0.01). In addition, the average explained variance (AVE) and composite reliability (CR) values (CR>AVE) calculated for convergent validity show that the convergent validity of the scale was supported. Cronbach alpha reliability and CR coefficient were 0.59 and 0.77, respectively, indicating internal consistency of the scale. Our results show that FAS II is a valid and reliable measurement tool that can be used to measure the socio-economic level.
