Examining the Construct Validity of the MMPI–2–RF Interpersonal Functioning Scales Using the Computerized Adaptive Test of Personality Disorder as a Comparative Framework

This study aimed to examine the construct validity of the Minnesota Multiphasic Personality Inventory–2 Restructured Form (MMPI–2–RF) interpersonal functioning scales (Ben-Porath &; Tellegen, 2008/2011 Ben-Porath, Y. S., &; Tellegen, A. (2011). MMPI–2–RF (Minnesota Multiphasic Personality Inventory–2 Restructured Form) manual for administration, scoring, and interpretation. Minneapolis: University of Minnesota Press. (Original work published 2008) [Google Scholar]) using as a criterion measure the Computerized Adaptive Test of Personality Disorder–Static Form (CAT–PD–SF; Simms et al., 2011 Simms, L. J., Goldberg, L. R., Roberts, J. E., Watson, D., Welte, J., &; Rotterman, J. H. (2011). Computerized adaptive assessment of personality disorder: Introducing the CAT–PD project. Journal of Personality Assessment, 93, 380–389.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Participants were college students (n = 98) recruited through the university subject pool. A series of a priori hypotheses were developed for each of the 6 interpersonal functioning scales of the MMPI–2–RF, expressed as predicted correlations with construct-relevant CAT–PD–SF scales. Of the 27 specific predictions, 21 were supported by substantial (≥ |.30|) correlations. The MMPI–2–RF Family Problems scale (FML) demonstrated the strongest correlations with CAT–PD–SF scales Anhedonia and Mistrust; Cynicism (RC3) was most highly correlated with Mistrust and Norm Violation; Interpersonal Passivity (IPP) was most highly correlated with Domineering and Rudeness; Social Avoidance (SAV) was most highly correlated with Social Withdrawal and Anhedonia; Shyness (SHY) was most highly correlated with Social Withdrawal and Anxioiusness; and Disaffiliativeness (DSF) was most highly correlated with Emotional Detachment and Mistrust. Results are largely consistent with hypotheses suggesting support for both models of constructs relevant to interpersonal functioning. Future research designed to more precisely differentiate Social Avoidance (SAV) and Shyness (SHY) is suggested.     

The Anxiety Depression Distress Inventory–27 (ADDI–27): New Evidence of Factor Structure,Item-Level Measurement Invariance,and Validity

Three studies examining the factor structure and psychometric properties of the Anxiety Depression Distress Inventory–27 (ADDI–27) extended the initial instrument development studies for this recently introduced inventory. The ADDI–27 is an empirically derived short form of the Mood and Anxiety Questionaire–90 (MASQ–90) comprising three scales: Positive Affect, Somatic Anxiety, and General Distress. The main objectives of Study 1 (N = 700) were to examine the factor structure of the ADDI–27 and its measurement invariance across gender at the item level. The objective of Study 2 (N = 538) was to examine evidence for the convergent and discriminant validity of scores on the ADDI–27. The objective of Study 3 (N = 240) was to assess further evidence for the nomological network and convergent and discriminant validity of the ADDI–27 scores. Results of exploratory structural equation modeling yielded strong support for a 3-factor model, with approximate fit indexes meeting or exceeding the conventional cutoffs. With p ≤ .001 as the criterion for detecting noninvariance, results of measurement invariance analysis suggested that all of the ADDI–27 items were invariant across gender. Results of multivariate validity analyses across 2 studies provided support for the convergent and discriminant validity of scores on the ADDI–27 scales.
