The generality of criminal behavior: A confirmatory factor analysis of the criminal activity of sex offenders in adulthood

The presence of a general construct of deviance had not been investigated in sex offenders in spite of the presumption of specialization that characterized them. Consequently, the aim of this study was to investigate whether sex offenders' criminal behavior could be explained by a general construct of deviance. A semi-structured interview was conducted with each subject in order to assess deviant behavior during the life course. The official criminal behavior of 388 convicted sex offenders was analyzed using confirmatory factor analysis. The pattern of covariance observed showed that the onset, frequency, and variety of criminal activity in adulthood could be explained by a general construct of deviance in sexual aggressors. The results, however, also suggested that child molesters' frequency of sexual crime was not part of a general construct of deviance. In other words, the offending behavior of sexual aggressors of women was predominantly versatile, whereas that of sexual aggressors of children tended to be more specific, at least for one dimension of their criminal activity.     

The effect of authority and social influence on eyewitness suggestibility and person recognition

This study investigated the influence of an authority figure on eyewitness identification. Participants watched a staged crime and then were administered a photo lineup by either an authority (policeman) or non-authority figure (civilian). Participants in the authority condition were more likely to choose a lineup member than those in the non-authority condition. There was no effect of authority, however, on the accuracy of the identification decisions. The lack of a deleterious effect suggests that the presence of a police officer during identification procedures does not create an unduly suggestive situation or have undesirable effects on eyewitness identification decisions. Although witnesses' choosing behaviors did not increase the rate of identification errors, the effect of the administrator's authority on choosing was reduced when unbiased instructions (vs. biased instructions) were presented to the witnesses. Thus, support was found for the use of neutral instructions during eyewitness identification procedures.     

Expectations regarding development during adolescence: Parental and adolescent perceptions

The aims of this study were (1) to compare the age-related expectations of parents and adolescents concerning the timing of achievement in a number of developmental tasks, (2) to examine whether personal characteristics of the adolescent affect developmental expectations, and (3) to examine whether discrepancies between the adolescents and the parents expectations are related to the amount of parent-adolescent conflict. The sample consisted of 508 families with adolescents (12–18 years old). During a home visit, a battery of questionnaires was administered individually to mothers, fathers, and adolescents. A new 24-item instrument to assess expectations for adolescents mastery of developmental tasks was developed for this study. Analyses showed that when the expectations of adolescents and those of their parents are compared at aggregate level, parents consistently indicate later ages for the achievement of developmental tasks than adolescents. Although parents have later timetables, parents and adolescents have strikingly similar views of the sequence in which achievement of developmental tasks should occur. The adolescents age appears to be the most potent predictor of developmental timetables, followed by gender, pubertal timing, and temperament, respectively. The amount of conflict within the parent-adolescent relationship was associated with differences in developmental expectations. The utility of the new instrument for research and clinical work is discussed.This research was supported by a grant from the Ministry of Health and Culture (PCOJ).
