The authors examined the construct validity of the Relationship Profile Test (RPT) with respect to measures of two related constructs-physical health and well-being (functional health status), and depression-linked personality type (anaclitic vs. introjective). In Study 1, the authors administered the RPT, Depressive Experiences Questionnaire (DEQ), and Medical Outcomes Study Short Form (MOS SF-20) to 116 undergraduate students. In Study 2, the RPT, DEQ, and MOS SF-20 were administered to 110, mostly African American female, primary care outpatients. Destructive Overdependence was positively correlated with anaclitic and introjective trait scores in both samples. Dysfunctional Detachment was positively correlated with introjective scores in both samples and with anaclitic scores in the primary care sample. Healthy Dependency was negatively correlated with introjective scores in both samples and with anaclitic scores in the primary care sample. These studies support the construct validity of the RPT in ethnically diverse nonclinical and clinical samples, and extend previous findings documenting links between RPT subscale scores and scores on measures of other theoretically related constructs.

Recently Perera et al. introduced two new binocular accuracy measures to evaluate diagnostic tests for paired organs. They adopted the Gaussian copula model to account for correlation between fellow eyes. As the measures are functions of several joint probabilities and due to the nature of the joint models, variations of the estimates for the two new measures were assessed via bootstrapping. We provide a different approach to inference about the two interesting and innovative measures. In our opinion, when patients are independent, the binomial models suffice for inference about the parameters of interest. Inference becomes simple and straightforward. We perform numerical studies and analyse the data set as of Perera et al. for illustration. Also, we investigate thru simulations the issue of robustness of the Gaussian copula and the binomial models under model misspecification.
