Sources of variability in the three-facet observational measurement design (m:f)ri
| Source | Type of variation | Variance component |
|---|---|---|
| Fathers (f) | Constant effect due to absence versus presence of fathers | σf2 |
| Mothers w. fathers (m:f) | Individual differences of mothers in parenting practice within fathers (Objects of measurement) | σmf2 |
| Raters (r) | Constant effect for all mothers due to stringency of raters | σr2 |
| Items (i) | Constant effect for all mothers due to inconsistencies of the level of parenting from one item to another | σi2 |
| fr | Inconsistencies in raters' stringency from one father condition to another | σfr2 |
| fi | Inconsistencies in item level of parenting from one father condition to another | σfi2 |
| (m:f)r | Inconsistencies of raters' stringency of particular mothers' parenting behavior | σ(m:f)r2 |
| (m:f)i | Inconsistencies from one item to another in particular mothers' parenting behavior | σ(m:f)i2 |
| ri | Constant effect for all mothers due to differences in raters' stringency from one item to another | σri2 |
| fri | Triple interaction indicating the extent to which the fi-interaction varies from one rater to another | σfri2 |
| (m:f)rie | Residual variation consisting of the unique combination of (m:f), r and i; unmeasured facets; and/or random events | σ(m:f)ri2 |
