Rorschach Validity Analysis

779 Words4 Pages

The validity of the Rorschach is difficult to compute for multiple reasons. Validity usually refers to how well a test measures a particular construct it intends to measure (Hess, 2001). The open-nature of the Rorschach yields a multitude of answers, which makes it difficult to compare outcomes among different individuals. Additionally, this test is utilized in multiple settings to measure multiple constructs such as intelligence, emotions, pathology, etc (Hess, 2001). The interpretation and score of the test depends on a single answer rather than a combination of responses which makes the validity difficult to interpret (Hess, 2001). Due to how time consuming the Rorschach is, research regarding the validity of this test is remarkably expensive …show more content…

Test-retest statistics provided were based on the NEO-PI-R. These statistics are not applicable to the NEO-PI-3 due to the multiple changes made to the NEO-PI-R (Benson, 2014). The only novel reliability statistics provided were internal consistency and interrater reliability values (Benson, 2014). Internal consistency for the five domains in the adolescent sample ranged from .87 to .93, and .88 to .95 for the adult sample (Benson, 2014). The facets yielded much lower internal consistency values ranging from .48 to .83 in the adolescents, and .56 to .86 for the adults (Bensons, 2014). Interrater reliability was assessed using cohen’s kappa, in adolescents the values ranged from .38 to .60, and in adults the values ranged from .52 to .65 (Benson, …show more content…

Criterion validity was assessed using the Spearman Rank-order Coefficient (Benson, 2014). The manufacturers found the correlation between the domains in NEO-PI-R and the NEO-PI-3 was quite high, ranging from .98 to .99 in both adolescents and adults (Benson, 2014). The range of correlation between facets were slightly lower, but still strong ranging from .83 to .98 in adolescents and .86-.99 in adults (Benson, 2014). Factor structure was examined to support construct validity. Results demonstrated the majority of the facets loaded onto each of their respective domains (Benson,

    However, in contrast, GNAT has very low reliability. The GNAT “does not ameliorate the concerns about the reliability of implicit measures, (Nosek and Banaji, 2001). However, its reliability can be improved by increasing the trials for the test, therefore, there will be more data points being calculated for the result. Secondly, use a variable response deadline; the participant can choose their own deadline, improving the accuracy across subjects. Finally, using the response latency approach within the GNAT test as its more reliable simply because each point is a continuous value.

    The Inconsistency index estimates the scores on an eight-item-pairs with the highest bivariate inter-item correlations from the development sample. The absolute difference of the item ratings is totaled and the scores are above the cutoff, the ratings are marked as potentially inconsistent. The self-report cutoff of the scores should be chosen in a way that less than 5% of the normative score sampling was rated as potentially inconsistent [47]. The MASC 2 appraises the probability of the incidence of any one of the anxiety symptoms based upon the profile of the elevations on the MASC 2

    Depending on the different answers, it showed this different risk levels to each student and their chance to become depressed. The Psychologist Hermann Rorschach discovered that when people responded to seeing more animals in the inkblot tests, they had a greater chance of becoming or suffering from depression. His other discovery was that the form of an interpretive test, could be used to help diagnose psychological disorders. But in this essay, the results were only to track the number of animals that the students depicted from each blot. A website that had similar blot tests to the ones done by Rorschach, and used that data to determine results.

    The text states,” But even Dr. Exner, the developer of the comprehensive system, agreed that the test "can be abused unwittingly by the ill-trained person," and he said he was uncomfortable with the use of the test in "adversarial" settings, like custody disputes.” The accuracy of these tests can definitely vary with the experience and training of the doctor who is distributing it, so only a few professionals have mastered being able to score the test properly. This clearly shows that the validity of these tests is questionable at best. Supporters of the Rorschach test say that the test is valid because it can delve into the mind of patient without requiring the patient to give up information they are not comfortable exposing. While this argument has some merit, the patient still has the ability to cheat the test by simply responding with the answers that make them look more mentally stable.

    Studies conducted on the Rorschach test provides a good example of this. It appears to be the most popular method in the United States, because it reports many criticisms of doubters. Several studies indicate that scores for fairly normal community samples of Mexicans, Central Americans, and South Americans often differ tremendously from the norms of the Exner’s system for scoring this test. These results increase the question of whether the test can be used ethically with Hispanic adults and children in the United

    The textbook discusses multiple different types of assessments; some of these include a self-report measure, informant reports, and by measuring behavior. Self-reports are usually manifested in questionnaires where an individual is asked to assess their own personality by ranking themselves based on statements or adjectives. On the other hand, informant reports come from people involved in the individual’s life. These usually work best for undesirable traits because an individual may not be aware of these traits or may not want to report that he possesses the traits. Measuring behavior is done through means of observation much like what is done in the movie I Heart Huckabees (Twenge & Campbell, 2016).

Many criticisms lie with its use in an unrelated sense, or in data where the values of the NHST do not further the argument or evidence of an experiment. It is important to remember that NHST can be used for certain situations, however, it cannot deviate and become a blanket statistical test for all data and

A country with this much diversity and tragic history, means psychological practitioners need to ensure there are cross-culturally fair test (Patterson & Uys, 2005). As much as the tests need to be appropriate for all, it is also important that practitioners are capable of administering those tests (Patterson & Uys, 2005).
