| One of the most widely used personality assessment instruments is the MMPI. Since its emergence into the field of psychological assessment in the late 1930's, the MMPI has gone through several revisions, all in the attempt to strengthen the reliability and the validity of this objective measure. Recently, a new instrument was introduced, the MMPI-2 RF. Since the MMPI-2 RF is such a novel instrument, there is a need for samples from different cultures and ethnic groups all over the world using this instrument. The cultural group selected for this study is an Israeli population of 75 subjects that have completed the MMPI-2, all from a normative sample. This archival sample was converted to MMPI-2 RF profiles and then compared with the MMPI-2 RF North American norms. The data from these two samples were analyzed on four scales: L-r, RC1, RC2, and RC4. These scales were selected because previous research indicates they may be especially sensitive to gender and cultural differences. The Israeli sample obtained a statistically significant higher score than the MMPI-2-RF U.S. normative sample on scales L-r, RC1, and RC4. With regards to the Israeli male and Israeli female samples, the Israeli male sample obtained significantly higher mean T scores on RC2 than the Israeli female sample, and higher mean T scores on RC4, however the differences were not statistically significant. An exploratory analysis between the Israeli male and the Israeli female samples on the remaining 47 scales revealed 2 statistically significant mean T score differences, with the Israeli male sample obtaining higher scores on MEC, and the Israeli female sample obtaining higher scores on MSF. Lastly, exploratory analysis between the Israeli sample and the MMPI-2-RF U.S. normative sample on the remaining 46 scales revealed 35 statistically significant mean T score differences Implications, limitations, and suggestions for future research are discussed. |
