Differential Item Functioning (DIF) with Multiple Indicator Multiple Causes (MIMIC) Model on Attachment Scale Between Muslim Orphanage Adolescents and Caregivers Based on Demographic Factors

Abstract

This research aims to see how the model of attachment between Muslim teenagers and their caregivers is based on demographic factors, namely gender. The Attachment Scale in this study is the Inventory of Parent and Peer Attachment-Revised (IPPA-R), which was compiled by Gay Armsden and Mark T. Greenberg in 2004 and revised by Gullone & Robinson (2005). This measures various qualities of the child's relationship with parents (mother, father, or caregiver) and friends. The quality of the relationship is seen from things such as trust, quality of communication and feelings of anger and alienation. Each statement in the research questionnaire has been adapted to the research context. This questionnaire has 25 items consisting of 3 subscales, namely trust consisting of 10 items, communication consisting of 9 items and alienation consisting of 6 items. This research involved 203 Muslim teenagers from 12 special Muslim orphanages in Pekanbaru City. DIF testing in this study uses MIMIC Model analysis. Based on the results of the first order CFA on a set of attachment items, there are 23 valid items. Then the results of the MIMIC model analysis based on gender found that the model fit the data where the RMSEA value = 0.012, so it was known that two items contained differential item functioning (DIF), namely item 7 (0.137, P = 0.002) and item 8 (0.309, P = 0.000).
