The constructs of intelligence and ego-resiliency are discussed. The personality implications of "pure intelligence" and "pure ego-resilience" were identified. Intelligence (IQ) was indexed by the Wechsler Adult Intelligence Scale-Revised and ego-resiliency by an inventory scale. Residual scores measuring "pure intelligence" and "pure ego-resilience" were correlated with the items of the observerbased California Q-sort, used to describe participants. Persons relatively high on ego-resilience tend to be more competent and comfortable in the "fuzzier" interpersonal world; persons defined primarily by raw IQ tend to be effective in the "clearer" world of structured work but tend also to be uneasy with affect and less able to realize satisfying human connections. Gender differences exist in the relations of ego-resilience and intelligence and in their adaptive relevance. We all know highly intelligent individuals who do not function well in the world in which they must live and who are psychologically maladjusted. And we all have encountered individuals not unusually endowed intellectually who nevertheless have achieved ways of living that are personally satisfying, socially constructive, and adaptationally creative. Such examples suggest that the long-standing emphasis of psychologists on the all-importance of intelligence for life adaptation is wanting; our psychological understandings require conceptual deepening. This article is an effort in that direction.

The 5-factor approach (FFA) to personality description has been represented as a comprehensive and compelling rubric for assessment. In this article, various misgivings about the FFA are delineated. The algorithmic method of factor analysis may not provide dimensions that are incisive. The "discovery" of the five factors may be influenced by unrecognized constraints on the variable sets analyzed. Lexical analyses are based on questionable conceptual and methodological assumptions, and have achieved uncertain results. The questionnaire version of the FFA has not demonstrated the special merits and sufficiencies of the five factors settled upon. Serious uncertainties have arisen in regard to the claimed 5-factor structure and the substantive meanings of the factors. Some implications of these problems are drawn.

The relation between psychological characteristics and drug use was investigated in subjects studied longitudinally, from preschool through age 18. Adolescents who had engaged in some drug experimentation (primarily with marijuana) were the best-adjusted in the sample. Adolescents who used drugs frequently were maladjusted, showing a distinct personality syndrome marked by interpersonal alienation, poor impulse control, and manifest emotional distress. Adolescents who, by age 18, had never experimented with any drug were relatively anxious, emotionally constricted, and lacking in social skills. Psychological differences between frequent drug users, experimenters, and abstainers could be traced to the earliest years of childhood and related to the quality of parenting received. The findings indicate that (a) problem drug use is a symptom, not a cause, of personal and social maladjustment, and (b) the meaning of drug use can be understood only in the context of an individual's personality structure and developmental history. It is suggested that current efforts at drug prevention are misguided to the extent that they focus on symptoms, rather than on the psychological syndrome underlying drug abuse.

The relation between overly positive self-evaluations and psychological adjustment was examined. Three studies, two based on longitudinal data and another on laboratory data, contrasted self-descriptions of personality with observer ratings (trained examiners or friends) to index self-enhancement. In the longitudinal studies, self-enhancement was associated with poor social skills and psychological maladjustment 5 years before and 5 years after the assessment of self-enhancement. In the laboratory study, individuals who exhibited a tendency to self-enhance displayed behaviors, independently judged, that seemed detrimental to positive social interaction. These results indicate there are negative short-term and long-term consequences for individuals who self-enhance and, contrary to some prior formulations, imply that accurate appraisals of self and of the social environment may be essential elements of mental health.
