Advancing knowledge about delinquency and crime: The need for a coordinated program of longitudinal research

Past research on delinquency and crime has provided convincing data about correlates but not about causes, because it has been largely cross-sectional in design. Whereas cross-sectional research focuses on variations between subjects, longitudinal research can provide information about changes within subjects, which are more important for causes, prevention, and treatment. Many of the most important results in criminology have been obtained in longitudinal or experimental studies, and the major studies of these types are reviewed here. It is now desirable to combine the two methods in a new coordinated program of longitudinal studies including experimental interventions or quasi-experimental analyses. Such projects could study several overlapping cohorts, extend from birth to adulthood, have frequent data collection, and obtain data from a variety of sources about many different types of antisocial behavior.     

Psychosocial predictors of adult antisocial personality and adult convictions

In the Cambridge Study in Delinquent Development, 411 South London males have been followed up since age 8. This article investigates the ability of psychosocial risk factors measured at age 8 - 10 to predict antisocial personality measures at ages 18 and 32 and convictions between ages 21 and 40. The most important childhood predictors were a convicted parent, large family size, low intelligence or attainment, and child-rearing factors, including a young mother and a disrupted family. The accuracy of prediction of antisocial personality at age 32 on the basis of childhood risk factors measured more than 20 years before was surprising: nearly half of boys with a convicted parent at age 10 were antisocial at age 32, compared with one in six of the remainder. Over 60% of boys very high risk at age 8 - 10 became antisocial at age 32. While the present research shows how far adult antisocial and criminal behavior can be predicted in childhood, more research is needed to establish the precise causal mechanisms involved.     

Protective Factors as Moderators of Risk Factors in Adolescence Bullying

The present study examined the role played by protective factors in moderating the effects of risk factors over bullying and victimization in a sample of 679 male adolescents recruited in Italian high schools. Boys’ involvement in bullying revealed that one in three students has bullied others at least sometimes in the previous three months, and one in six has been victimized at the same rate; victimization decreases with age. The family related risk factor (conflicting parents) was positively associated with bullying and with victimization (together with punitive parenting); the same applied for risk factor related to the individual ways of dealing with problems (emotionally oriented coping skills). Protective factors related to the family context (supportive and authoritative parents) and to the individual (problem solving coping skills) were negatively associated to bullying and victimization. Hierarchical regression analyses revealed a moderating effect of supportive parenting on punitive parenting and on emotionally oriented coping strategies in predicting victimization. Problem solving coping strategies helped buffer the negative impact of emotionally oriented coping strategies over bullying. Implications of results for practitioners and for future studies are addressed.     

Grandiose-Manipulative,Callous-Unemotional,and Daring-Impulsive: the Prediction of Psychopathic Traits in Adolescence and their Outcomes in Adulthood

There has been much debate about how to measure psychopathic traits in adolescence. One of the main issues is whether one should focus on callous-unemotional (CU) traits alone, or CU traits in combination with Grandiose-Manipulative (GM) and Daring-Impulsive (DI) traits. The current study first investigates the extent to which youth who are high on CU traits are also high on GM and DI traits. In addition, the study investigates if being high on both CU and GM, and high on both CU and DI, identify groups that are particularly characterized by past and future impairments. To investigate this, data from the Cambridge Study in Delinquent Development (CSDD) was analyzed. The CSDD is a prospective longitudinal study of 411 English boys spanning over 50 years. The information available at age 12–14 was coded on the Antisocial Process Screening Device (APSD). Childhood risk factors were measured at age 8–10 and later life outcomes were measured at age 32. The results indicate that being high on CU in combination with DI delineates a clinically interesting group who are characterized by high childhood risk and poorer adult life outcomes. The same applied to the high CU/high GM group, but to a lesser extent.     

The development of violence from age 8 to 61

The main aim of this study is to investigate the development of violence from childhood to adulthood. In the Cambridge Study in Delinquent Development (CSDD), 411 London males have been followed up from age 8 to 48 in interviews, and from age 10 to 61 in criminal records; 19% were convicted for violence. There was a surprising amount of violence committed at older ages (40–61). The number of violence convictions was similar at ages 10–20, 21–39, and 40–61. There was considerable continuity in violent offending from ages 10–20 to 40–61. There was also continuity in self-reported violence from ages 15–18 to 43–48, and violence convictions were related to self-reported violence at all ages. The most important childhood risk factors for violence convictions were high daring or risk-taking, low verbal intelligence, a disrupted family, harsh parental discipline, high hyperactivity, and large family size. The extent to which these risk factors predicted violence at ages 40–61 was noteworthy. The “integrated cognitive antisocial potential (ICAP)” theory was proposed to explain the development of violence, and methods of preventing violence, targeting childhood risk factors, were reviewed.     

Evaluation of an intervention program for the reduction of bullying and victimization in schools

The present study evaluates the effect of an intervention program on the reduction of bullying and victimization in schools with a sample of 239 students aged 10–16 years old in Rome, Italy. The program deals with bullying and violence. It consists of three videos and a booklet that help students to develop the social cognitive competence skills to understand the negative consequences of aggressive behavior. The intervention was evaluated using an experimental design with pre‐test and post‐test analyses. Students were randomly allocated to experimental or control classes. Students completed a self‐report questionnaire in which they were asked to indicate on a 5–point scale how often they were victimized or bullied others. Victimization and bullying were assessed by using questions about specific types of actions, a composite measure of victimization and bullying, and a single question about victimization and bullying in general. Results showed that the program worked best for older students, but not for younger ones who in some cases reported an increased level of victimization after the intervention. For older students there was a decrease in victimization according to the sum of types of behavior for the experimental group, but an increase for the control group. The same result was found for direct victimization, having belongings stolen, and being called nasty names. Therefore, the program seemed to be beneficial for older students but possibly damaging for younger students. It is suggested that the program could have worked better with older students because of the cognitive skills it required. Younger students could have reported higher levels of bullying after the intervention because they became more sensitized to the topic of bullying. Aggr.

Crime prevention: more evidence-based analysis

This paper introduces a new section of Psicothema dedicated to the evidence-based approach to crime prevention. Along with an original sexual-offender-treatment programme implemented in Spain, this section presents four systematic reviews of important subjects in the criminological arena, such as sexual offender treatment, the well-known programme, the effectiveness of custodial versus non-custodial sanctions in reoffending and the fight against terrorism. We also highlight some of the focal points that scientists, practitioners and governments should take into account in order to support this evidence-based viewpoint of crime prevention.     

Examining the relationship between low empathy and bullying

This paper investigates the relationship between cognitive and affective empathy and bullying. A bullying questionnaire was completed by 376 males and 344 females aged about 15 in Hertfordshire. Low affective empathy was significantly related to bullying for females, but not for males. However, for both males and females low affective empathy was related to frequent vs. occasional bullying. Low total empathy was related to violent bullying by males and to indirect bullying by females. Cognitive empathy was not significantly related to any type of bullying by males or females. Aggr.

Measuring the difference limen for identification of order of onset for complex auditory stimuli

The approximately 20-msec perceptual threshold for identifying order of onset for components of auditory stimuli has been considered both as a possible factor contributing to the perception of voicing contrasts in speech and as no more than a methodological artifact. In the present research, we investigate the identification of the temporal order of onset of spectral components in terms of the first of a sequence of thresholds for complex stimuli (modeled after consonant-vowel [CV] syllables) that vary in degree of onset. The results provide clear evidence that the difference limen (DL) for discriminating differences in onset time follows predictions based on a fixed perceptual threshold or limit at relatively short onset differences. Furthermore, the DL seems to be a function of context coding of stimulus information, with both the DL and absolute threshold probably reflecting limits on the effective perception and coding of the short-term stimulus spectrum.
