Use of the MMPI-2 in American Indians: I. Comparability of the MMPI-2 Between Two Tribes and With the MMPI-2 Normative Group

Detecting psychotic symptoms in Indigenous populations: a review of available assessment tools

As efforts to shorten the duration of untreated psychosis increase, there is a need for short screening instruments to identify those at-risk. It is feared that remote Indigenous populations, manifesting many of the risk factors associated with schizophrenia and often lacking access to adequate mental health services, may be overlooked as the general population effort shifts towards early detection. This article aimed to review studies investigating psychotic symptoms in Indigenous communities in Australia, New Zealand, Canada and United States of America and aimed to evaluate the usefulness of the instruments. Eleven relevant studies were identified using seven unique instruments. The available instruments assessed psychotic symptoms to varying degrees, although no screener for early detection was found thus supporting concerns that these disadvantaged populations do not have access to suitable support enabling early detection of psychosis. We recommend that a rapid screening tool for detecting at-risk individuals be developed and validated for community use in Indigenous populations living in remote areas.

2010 Bruno Klopfer Distinguished Contribution Award. Some considerations for enhancing psychological assessment

The field of psychological assessment appears to be bogged down in recent decades on refining existing measures and techniques to the detriment of real change. This article attempts to highlight some of the changes that need to take place in psychological assessment in the next few decades if real progress is to be achieved: (a) developing guidelines for psychological tests and measures; (b) establishing explicit criteria for training; (c) establishing guidelines for competencies; (d) recognizing the impact of marketing; (e) embracing electronic technology; and (f) implementing computer adaptive testing.

ANALYSIS OF DEMOGRAPHIC FACTORS ON F SCORES AND EVALUATION OF NEW CONFIGURATIONS OF F SCALES

We analyzed the influence of demographic factors on scores of the Infrequency scale of the MMPI (Archer, Gordon, & Kirchner, 1987) administered to male youth in China. The demographic factors, acting as influencing factors of F scores, could be ignored. New configurations of infrequency scales were presented and discussed, which indicated that it was appropriate to choose a 20% item endorsement percentage (IEP) of the Chinese male youth as the criterion for item selection.

A cultural-contextual perspective on the validity of the MMPI-2 with American Indians

This study investigated the normative validity of the MMPI-2 with two distinct American Indian tribes. Differences occurred on 8 of the 13 basic validity and clinical scales (F, 1, 4, 5, 6, 7, 8, 9) between the MMPI-2 norms and both tribal samples. Elevated MMPI-2 scores of American Indians may not only reflect the possibility of psychological distress spurred by historical oppression and present adversity, but also an expression of a divergent worldview. Considering the context of the historical and social production of knowledge about American Indians, it is argued that researchers and practitioners, when interpreting MMPI-2 results for American Indians, should seriously consider their interpretive points of reference, which may be impacted by dominant cultural belief systems.

Measurement issues in health disparities research

BACKGROUND

Racial and ethnic disparities in health and health care have been documented; the elimination of such disparities is currently part of a national agenda. In order to meet this national objective, it is necessary that measures identify accurately the true prevalence of the construct of interest across diverse groups. Measurement error might lead to biased results, e.g., estimates of prevalence, magnitude of risks, and differences in mean scores. Addressing measurement issues in the assessment of health status may contribute to a better understanding of health issues in cross-cultural research.

OBJECTIVE

To provide a brief overview of issues regarding measurement in diverse populations.

FINDINGS

Approaches used to assess the magnitude and nature of bias in measures when applied to diverse groups include qualitative analyses, classic psychometric studies, as well as more modern psychometric methods. These approaches should be applied sequentially, and/or iteratively during the development of measures.

CONCLUSIONS

Investigators performing comparative studies face the challenge of addressing measurement equivalence, crucial for obtaining accurate results in cross-cultural comparisons.

Cross-cultural alexithymia: validity of the 20-item Toronto Alexithymia Scale in North American aboriginal populations

OBJECTIVE

The generalizability of the alexithymia construct to North American aboriginal culture was examined by assessing the replicability of the factor structure of the 20-item Toronto Alexithymia Scale (TAS-20) in two different adult samples. The study also assessed the reliability of the scale and the influence of gender, age, and education on alexithymia levels.

METHOD

The first sample was a community-based group of 123 aboriginal men and women; the second sample was 102 male aboriginal offenders. Both samples completed the TAS-20.

RESULTS

The replicability of the three-factor structure for the TAS-20 was supported in both groups using confirmatory factor analysis (CFA). The TAS-20 and its three factors demonstrated adequate internal reliability, and the variables of gender, age, and education accounted for small or nonsignificant amounts of variability in total TAS-20 and factor scale scores.

CONCLUSION

The results provide additional support for the factorial validity of the TAS-20 in diverse cultural groups.

Use of the MMPI-2 in American Indians: II. Empirical correlates

R. W. Robin, R. L. Greene, B. Albaugh, A. Caldwell, and D. Goldman (2003) reported that members of 2 American Indian tribal groups had statistically significant higher T scores on several MMPI-2 clinical, content, and supplementary scales than did the MMPI-2 normative group. The present study investigated the empirical correlates of the MMPI-2 scales in these American Indian tribal members. There were a large number of significant correlates reflecting antisocial symptoms with Scales 4 (Psychopathic Deviate), 9 (Hypomania), Anger, and Antisocial Practices. There were even a larger number of significant correlates reflecting generalized distress and negative affect with Scales 7 (Psychosthenia), 8 (Schizophrenia), Anxiety, Obsessions, Depression, and Welsh Anxiety. The rationally derived MMPI-2 content scales generally had larger correlations with these constructs than the clinical scales. Thus, the differences reported by R. W. Robin et al. (2003), appear to reflect behaviors and symptoms that American Indians participants were experiencing rather than test bias.
