The family of origin scale: A construct validation study

The Family of Origin Scale in Greece

“…The Cronbach's alpha was found to be .95, a value that is considered sufficiently high. Analogous alpha values of .96 were found in the studies by Gavin and Wamboldt (1992) and Ryan et al (1994). With regard to the item-total correlations, no item had a negative item-total correlation and all but one item-total correlation ranged from 0.28 to 0.74, and for 29 items these correlations were in the 0.40 t 0.69 range.…”

“…This seven-factor solution, a solution similar to that of Ryan et al (1994), Mazer et al (1990), and Kline and Newman (1994) studies, accounted for 60.72% of the total variance. The individual items retained in the model and factor loadings are presented in Table 2, together with the communalities (h 2 ), eigenvalues and the percentage of variance explained.…”

“…The second factor, which accounted for 5.63% of the variance, emerged in others studies as well (e.g., Mazer et al, 1994;Ryan et al, 1994;Lee et al, 1989). The second factor was composed exclusively of the four items from the "Acceptance of Separation and Loss" subscale of the FOS, which is part of the Autonomy concept.…”

“…In order to examine the structural characteristics of the FOS, an exploratory factor analytic procedure (EFA) was employed to discover the factor structure and to examine internal reliability. It should be additionally noted that most of the studies that factor analysed the FOS have chosen as the main factor analytic procedure the exploratory technique of principal components analysis with orthogonal varimax rotation solution (Ryan et al, 1994;Kline & Newman, 1994;Mazer et al, 1990;Gavin & Wamboldt, 1992;Lee et al, 1989) although there are exceptions .…”

“…PCA was the standard procedures in the major previous studies using the FOS (Lee et al, 1989;Gavin & Wamboldt, 1992;Kline & Newman, 1994;Mazer et al, 1990). MLF was also used with caution since it was the factor extraction method performed in Ryan's et al (1994) study. This caution was justified by the fact that according to some researchers (e.g., Srholec & Verspagen, 2008) this method requires multivariate normality of the data which is not a viable assumption for a dataset consisting of binary and Likert scale variables.…”
