Emotional intelligence competences of three different ethnic groups in Indonesia

This study attempts to provide a portrayal of emotional intelligence (EI) of the Indonesians, one of the fourth most populous countries and multiethnic societies in the world, specifically across the 404 Bataks, 430 Minangkabau, and 479 Javanese ethnics. The result indicated that the Indonesian version of the EQ-i is invariant across the three ethnic groups. The findings also showed that the three ethnic groups have some shared characteristics in terms of interpersonal, assertiveness, empathy, social responsibility, flexibility, and problem-solving competences. We found significant main effects of ethnicity and gender as well as the interaction effect on EI competences. Cross-ethnic comparison showed that the Minangkabau assessed in this study are the most underdeveloped group in terms of social and emotional capabilities. We recommend replications of this study for other Indonesian ethnic groups to draw a more valid conclusion and to support the development of society.     

One-way analysis of proportions for misclassified binomial data

We consider data with a nominal grouping variable and a binary response variable. The grouping variable is measured without error, but the response variable is measured using a fallible device subject to misclassification. To achieve model identifiability, we use the double-sampling scheme which requires obtaining a subsample of the original data or another independent sample. This sample is then classified by both the fallible device and another infallible device regarding the response variable. We propose two Wald tests for testing the association between the two variables and illustrate the test using traffic data. The Type-I error rate and power of the tests are examined using simulations and a modified Wald test is recommended.     

Bayesian Inference of Odds Ratios in Misclassified Binary Data with a Validation Substudy

We propose a fully Bayesian model with a non-informative prior for analyzing misclassified binary data with a validation substudy. In addition, we derive a closed-form algorithm for drawing all parameters from the posterior distribution and making statistical inference on odds ratios. Our algorithm draws each parameter from a beta distribution, avoids the specification of initial values, and does not have convergence issues. We apply the algorithm to a data set and compare the results with those obtained by other methods. Finally, the performance of our algorithm is assessed using simulation studies.     

Adult Attachment Stability–Instability Before and After Marriage Between Intimate Partner Violence (IPV) and Non‐IPV Women Separated from Partners During Military Duty in Indonesia

The quality of attachment between intimate partners is important for women to maintain healthy relationships. Yet, the quality of attachment style and relationship can be marred and disrupted in women exposed to trauma due to intimate partner violence (IPV). Research suggests that the impact of trauma on women can be transmitted over generations due to the inability to regulate emotions, specifically in dealing with their children. The aim of this study was to explore the disruption of adult attachment patterns by comparing a group of women in Indonesia who have been affected by IPV, and a group of women who have not been affected by IPV but who have been separated from their partner during military duty. A cross‐sectional study comparing two groups: women exposed to IPV (n = 35) and women not exposed to IPV (n = 35) was carried out. The adult attachment scale before and after marriage was obtained using Experiences in Close Relationships‐Revised scales. The results revealed a significant shift of attachment style on the Avoidant dimension of the non‐IPV group separated by partner military duty and a slight change on the overall attachment of the IPV group, but relative stability on the Anxiety dimensions. The study interpreted the findings as being more supportive of the prototype perspective rather than the revisionist perspective. Family therapists may reduce the attachment Avoidant dimension as a therapeutic goal of intervention to change the insecure to a more secure working model.
