Whither goest our redoubtable mentor, the MMPI/MMPI-2?

Four areas of MMPI use and development toward the year 2000 and beyond are discussed. First, although the MMPI-2 booklet is a clear improvement, we will continue to need to use both profiles, the MMPI-2 for normative purposes and the MMPI profile for pattern interpretation. Applying MMPI expectations to MMPI-2 profiles is a violation of Meehl's basic actuarial prediction concepts. Secondly, as psychologists begin prescribing medications, we may be able to substantially refine drug choices. Thirdly, the measurement of socioeconomic status levels appears to be the major, missing moderator variable in MMPI/MMPI-2 interpretation. Lastly, an effective and positive MMPI/MMPI-2 feedback paradigm is discussed that fits well within the managed care context.     

Social support: Its structure and impact on marital disruption

Availability of social support has been hypothesized to play a role in influencing adjustment to marital disruption either directly or by moderating the debilitating effects of stress. Yet previous research has not adequately conceptualized or measured the nature and availability of social support. In an effort to learn more about the structure and impact of social support as it relates to marital disruption, 50 newly separated men and women were interviewed at 2 months and again at 8 months after their separations. The structure of social support was found to include (a) several important sources of support, including family, friends, and the larger community; (b) an index of social activity; and (c) a sense of satisfaction with present marital status. Although the stress associated with separation was positively related to poorer adjustment, certain aspects of social support were found to moderate this relationship. This report is based, in part, on work supported by National Institute of Mental Health grant No. MH 26373 (Preventive Intervention for Newly Separated Persons), Bernard L. Bloom and William F. Hodges, co-principal investigators. We are pleased to acknowledge this support.     

Beyond change management: a multilevel investigation of contextual and personal influences on employees' commitment to change

The extent to which attitudes toward organizational changes may be affected by contextual (other changes going on) and personal (self-efficacy) factors was investigated with a multilevel design involving 25 different changes. Even after aspects of the change itself were controlled, the interaction between the context and the individual difference explained significant variance in attitudes toward those specific changes. The positive relationship between self-efficacy and commitment to the change was stronger as the amount of simultaneous and overlapping change in the surroundings increased. The implications for research and practice are discussed.     

Psychopathy and behavioral correlates of victim injury in serious juvenile offenders

The study examines delinquent behavior and psychopathy and assesses their relationship to victim injury in a population of 168 incarcerated juvenile delinquent males with lengthy histories of criminal and violent behavior. A series of multiple regressions found that 17% of the variance associated with level of victim injury was accounted for by a model that included the three-factor model of the Psychopathy Checklist: Youth Version [Forth, Kosson, and Hare, 2003], criminal versatility, and age of onset of criminal offending. Notably, anger and DSM-IV symptoms of conduct disorder were not related to level of victim injury. The results of this study support an escalation hypothesis where individuals with earlier onset to criminal behavior and greater criminal versatility escalate to more severe violence. The current results demonstrate the importance of integrating established theories of juvenile delinquency when explaining severe violence in youth.     

Low-dose mecamylamine improves learning of rats in the radial-arm maze repeated acquisition procedure

The nicotinic antagonist mecamylamine has been widely shown to cause cognitive impairment. However, these effects are mainly seen with high doses. There have been scattered findings that low doses of mecamylamine can have the opposite effect. This may be due to opposite effects of low doses of mecamylamine. In the current study, an extensive dose-effect function of mecamylamine was characterized in the low-dose range. Adult female Sprague-Dawley rats were trained on a repeated acquisition procedure on an automated 8-arm radial maze. Three of the eight arms were designated as correct for any particular session. Five trials per session were run. The number of errors per trial to find the three correct arms was determined. The rats were trained on the repeated acquisition procedure for at least 18 sessions at which time they showed reliable learning each session. Then, the effect of low doses of mecamylamine between 0 and 1 mg/kg were assessed in a repeated measures counterbalanced design. This dose range of mecamylamine did not affect performance on the first trial when the rats were na?ve to the array to be learned. On trials 2-5 a significant (p<.025) quadratic dose-effect function was seen over this dose range. The most substantial effect was seen with 0.125 mg/kg of mecamylamine, which caused a significant (p<.05) improvement relative to the saline control condition. The effect diminished with increasing mecamylamine doses and with the 1 mg/kg dose choice accuracy was back to control levels. This study showed that low doses of mecamylamine can effectively improve learning. A U-shaped dose-effect curve was documented. This suggests possible low-dose nicotinic antagonist lines of treatment for cognitive impairment.     

What does it mean to be angry at yourself? Categories, appraisals, and the problem of language

According to appraisal theorists, anger involves a negative event, usually blocking a goal, caused by another person. Critics argue that other-agency is unnecessary, since people can be angry at themselves, and thus that appraisal theory is wrong about anger. In two studies, we compared anger, self-anger, shame, and guilt, and found that self-anger shared some appraisals, action tendencies, and associated emotions with anger, others with shame and guilt. Self-anger was not simply anger with a different agency appraisal. Anger, shame, and guilt almost always involved other people, but almost half of the occurrences of self-anger were solitary. We discuss the incompatibility of appraisal theories with any strict categorical view of emotions, and the inadequacy of emotion words to capture emotional experience.
