The MMPI-2-RF normal sample is the same used to standardize the MMPI-2 minus the emphasis on gender; no new norms were collected for the MMPI-2-RF. The nongendered MMPI-2-RF normative sample is made up of 1,138 men and 1,138 women from the normative sample of the MMPI-2. Analysis of T scores based on gendered versus nongendered norms showed no advantages or disadvantages for either gender. The mean T scores for both men and women were at or about 50, with standard deviation of 10; therefore, there was no significant clinical difference between genders. The normative sample was composed of individuals ranging from age 18 to 80 all from different regions and communities in the United States. The representation of ethnicities is slightly skewed; Caucasians are overly represented and Asians and Hispanics are underrepresented. The MMPI-2-RF scores are non-K-corrected due to overwhelming data showing that K correction does not benefit, and at times, weakens the distinction between the norm group and the individuals being tested (Porath, 2012).
Interpreting The MMPI-2-RF included a vast amount of information about the reliability data in the MMPI-2-RF. For example, the scores on the Somatic/Cognitive Scales, Internalizing Specific Problems Scales, Externalizing Specific Problems Scales, and Interpersonal Scales amongst others were reliable based on test-retest correlations and internal consistency estimates in clinical studies. The empirical data offered by the Technical Manual shows strong and distinctive correlational findings, and consistent measures of the constructs the scales target. These findings provide strong evidence supporting the construct validity and reliability of the 51 Scales found in the MMPI-2...

The sample used to norm the test was inclusive, and studies have showed little to no discrepancies in scores in regards to demographics (gender, ethnicity, socioeconomic status). I found limited data regarding the exactly reliability coefficients and the validity of the test. However, I did discover this test to be used when determining concurrent validity of other tests of anxiety. There are no limits to this test in regards to a population or administration, as it is written at an elementary reading level and provides multiple administration types (verbal, audio CD, reading) and response types (verbal or nonverbal). The only area of limitation that I believe exists with this test is its vulnerability to self-report biases, affecting the accuracy of the scores produced for children. I feel very comfortable using this measure in my profession, and believe it can provide a strong base for assessing a child’s anxiety levels and their impacts socially or

Since it was designed as a self-report tool that assesses a broad scope of clinical conditions, its reliability and validity can be considered as strong. In its 478 items, the MMPI-A covers the 10 original scales of MPPI, six validity scales, PSY-5 scales, and 15 content component scales. Then there are also three social introversion sub-scales, the 31 Harris Lingoes sub-scales and six supplementary scales. More importantly, studies of the MMPI-A have shown high test and retest consistency through which reliability and validity can be guaranteed (Gass & Odland, 2012). With the exception of the MF scale that is part of the four factor model, the remaining three which are General Maladjustment, Social Introversion and Over-Control, relevantly address the behavioral problems exhibited by Jane. Hence, it is imperative that the racial disparity of the MF scale be considered from a cultural perspective because studies have shown that there is a tendency of non-Whites scoring higher than other races (Gass & Odland, 2014). Ideally, the variations in cultural values must be considered when applying the test on Whites and non-Whites since the differences reflect socio-economic factors rather than racial

The MACI consists of a 160-item inventory, provided in the English and Spanish language, with a combination of the 27 subscales. The intention of the inventory is to provide counselors and other healthcare or school professional with information to assist in diagnosis and treatment planning for personality disorders in adolescent (Millon & Davis, 1993). The inventory consists of true or false questions; given that this inventory is shorter compared to other personality assessment, it only takes about 20-30 minutes to complete. Millon’s MACI inventory provides convenient and cost-effective methods for scoring the inventory, which include Q-global web-based scoring, Q-Local software-based scoring, and mail-in scoring. Since the MACI is tailored toward adolescents ranging in ages from 13-19, participants must have a minimum of a sixth grade reading level in order to
The composite score is objective and calculated through a weighted formula designed to provide an equal contribution from each item while the severity rating is subjective and indicates the need for additional treatment in specific areas (Haraguchi et al., 2009). The SR ranges from 0 to 9 points and the CS ranges from 0 to 1 with anything higher than the normal 9 SR or 1 CS indicating greater problem severities (Haraguchi et al., 2009). Although some problems still exist, the ASI has been reported to have nearly achieved both reliability and validity (Haraguchi et al.,

A widely used checklist is provided so the reader can get a wide spanning view of what is accounted for when scoring a psychopath. This form of research is very important within the deceitfulness of this population; it allows the professional to ignore their words and examine their actions. Hare made it clear that it is not uncommon for there to be an emotional and verbal disconnect from their actions. With virtually no emotional functioning psychopaths feel no remorse for the offenses that they commit and it is very important that we work towards using the opportunities we have to study and assist these populations; not only for them but for ourselves.

The Values and Motives Questionnaire (VMQ) manual explained two types of reliability that they utilized to assess the consistency of the assessment: test-retest reliability and homogeneity reliability (Psytech, 2016). The test-retest reliability assesses compares the scales that occurred at two or more separate testings, whereas the homogeneity assesses if the items within the test are similar in their ability to test the target attribute. (Drummond, Sheperis, & Jones, 2016). The two types of validity the VMQ manual acknowledged wereconstruct and criterion validity (Psytech, 2016). Construct validity is an assessment that tests if the target attribute is effectively being measured. The test needs to reflect meaning and be consistent with other established tests measuring the same attribute. Criterion validity measures the tests ability to predict the target attribute successfully, this is especially important since most assessment are given in order to predict wellness or behaviors (Drummond et al., 2016). The primary reliability assessment used to portray reliability in the manual is the homogeneity. It was reported that all of the scales have a strong measurement, except for achievement and infrequency (Psychnet, 2016). This means that of all the sub-categories that are in the VMQ are asking questions that are similar in their measurement of the target category. For validity, the inter-correlations were assessed. The results indicated that the sub-scales did not directly impact each other and that they did measure the specific sub-scales they were intending to measure (Psychnet, 2016).
