Self-regulation therapy to reproduce drug effects: a suggestion technique to change personality and the DRD3 gene expression

Experiencing Effects of Cocaine and Speed with Self-Regulation Therapy

This study demonstrates the efficacy of Self-Regulation Therapy (SRT) to induce effects of cocaine and speed in a single session. SRT is a suggestion procedure of sensorial recall exercises (salivation, feeling of weight, tension, etc.) that increases the capacity to reproduce all sensation types and those that drugs produce. The Self-Regulation Scale (SRS) measures this capacity. Four groups participated, formed according to drug use: Group 1 (uses no illegal drugs); Group 2 (experimentally uses cannabis only); Group 3 (moderate drug users); Group 4 (regular drug users, especially stimulants). All four groups participated in an SRT session to induce relaxation. No differences in the SRS were found. Group 4 also participated in a session that reproduced effects of drugs with SRT, when Euphoria and the Effects of drugs score (high and rush) substantially increased in relation to the base-line (MD = -5.83; p < .001; and MD = -3; p < .001, respectively) and in relation to the relaxation session (MD = -4.06; p < .001; and MD = -1.96; p < .05, respectively). A profile predicting SRT efficacy was also obtained to induce the effects of cocaine and speed: low Conscientiousness and high Openness and SRS scores. Finally, the potential use of this procedure to treat addictions, and strategy development towards more controlled, responsible drug use, are discussed.

From the big five to the general factor of personality: a dynamic approach

An integrating and dynamic model of personality that allows predicting the response of the basic factors of personality, such as the Big Five Factors (B5F) or the general factor of personality (GFP) to acute doses of drug is presented in this paper. Personality has a dynamic nature, i.e., as a consequence of a stimulus, the GFP dynamics as well as each one of the B5F of personality dynamics can be explained by the same model (a system of three coupled differential equations). From this invariance hypothesis, a partial differential equation, whose solution relates the GFP with each one of the B5F, is deduced. From this dynamic approach, a co-evolution of the GFP and each one of the B5F occurs, rather than an unconnected evolution, as a consequence of the same stimulus. The hypotheses and deductions are validated through an experimental design centered on the individual, where caffeine is the considered stimulus. Thus, as much from a theoretical point of view as from an applied one, the models here proposed open a new perspective in the understanding and study of personality like a global system that interacts intimately with the environment, being a clear bet for the high level inter-disciplinary research.
