Increase in self-rejection and continuing/discontinued deviant response

It was hypothesized that adoption of deviant response patterns regardless of subsequent continuation of the act would be associated with an antecedent increase in negative self-attitudes. Subjects were seventh-grade students who responded to a questionnaire three times (T ₁,T ₂,T ₃) at annual intervals (N=3,148). Self-attitudes were measured by a seven-item self-derogation scale. Change in self-derogation was determined by expressing the posttest score as a deviation from the posttest-on-pretest regression line. Deviant responses were defined in terms of self-reports of each of 22 highly independent responses. In all cases, as hypothesized, for each of the 22 deviant responses both (1) subjects who adopted and continued the act and (2) subjects who adopted and discontinued the act manifested greater increases in self-derogation than subjects who did not adopt the deviant act. The differences, all of which were in the hypothesized direction, were significant in 34 of the 44 comparisons. The results were interpreted as supporting the position that the adoption of any of a broad range of manifestly dissimilar deviant responses is preceded by the genesis of negative selfattitudes.Received his Ph.

Current research interests are social psychiatry and, more specifically, the reciprocal relationship between self-attitudes and the adoption of deviant response patterns.     

Deviant behavior and self-enhancement in adolescence

The hypothesis that “among initially high self-derogation subjects deviant response patterns (alcohol and drug abuse, delinquent patterns, etc.) are related to subsequent decreases in self-derogation” was tested with data from a longitudinal survey study of adolescents. Among higher and lower socioeconomic status (SES) males initially high self-derogation subjects who adopted (relative to those who did not adopt) any of several deviant patterns manifested significantly greater subsequent base-free decreases in self-derogation. For higher SES females only narcotics use (and among lower SES females no deviant pattern) was significantly related to subsequent decrease in self-derogation. Together with collateral data, these results indicated that where the deviant patterns were compatible with valued social roles and the subjects were able to defend against negative responses by others (but not under mutually exclusive conditions), deviant patterns functioned to reduce self-rejecting feelings among initially highly self-derogating subjects.

Identification of N,N-dimethylamphetamine formed by methylation of methamphetamine in formalin-fixed liver tissue by multistage mass spectrometry

Methamphetamine is methylated in the presence of unbuffered formalin solutions within hours at room temperature. The product, N,N-dimethylamphetamine, is also found in human liver exposed to methamphetamine followed by incubation with formalin. In the present study, a direct mass spectrometric method was developed to identify N,N-dimethylamphetamine in human liver before and after treatment with formalin. Human liver samples were obtained from four deaths that were investigated by the West Virginia Office of Chief Medical Examiner. Full toxicological analysis was conducted on samples from the decedents and methamphetamine was among the positive findings in each case. The method used to expose liver tissue to formaldehyde involved treating a small piece of liver from each case with formalin solution (20% v/v) for 24 h at room temperature. The formalin treated tissues were homogenized and the resulting suspension was sonicated for 5 min, and then centrifuged. Supernatant aliquots were directly analyzed by electrospray ionization (ESI) mass spectrometry without chromatographic isolation. Positive ion multistage mass spectra recorded in MS, MS/MS and MS/MS/MS (MS3) modes were used to confirm the presence of N,N-dimethylamphetamine and methamphetamine in the mixture. Liver tissue not treated with formalin did not contain a detectable level of N,N-dimethylamphetamine. Decreases in methamphetamine concentrations in liver tissue resulting from treatment with formalin were measured using deuterium-labeled methamphetamine as internal standard. The method can be completed in less than 2 h on thawed tissue. The results suggest that the process of fixing tissues with formalin may lead to false negative findings for methamphetamine.
