Abstract:
The purpose of the current study was to examine the relative utility of the most updated MMPI adult instrument, the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF), which was designed to address psychometric limitations of the MMPI-2. To this end, we compared mean scores and correlates of emotional distress treatment outcomes using the Depression Anxiety Stress Scales in a sample of 230 patients (73 males, 157 females) who had completed an interdisciplinary chronic pain rehabilitation program. Structural equation modeling analyses indicated that higher scale scores from all the MMPI-2-RF substantive domains were meaningfully associated with worse emotional distress outcomes, whereas the MMPI-2 Clinical Scales generally did not have any meaningful associations. Similar results were found in additional analyses using a clinically significant change framework with more direct clinical implications. The results of this study provide preliminary support for the use of the MMPI-2-RF among patients with chronic low back pain.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...
SN2 Reaction: Mechanism
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...
SN2 Reaction: Transition State
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
