The present study examined the genetic and environmental etiology of decision-making (Iowa Gambling Task; Bechara, Damasio, Damasio, & Anderson, 1994), in a sample of twins at ages 11-13, 14-15, and 16-18 years. The variance across five 20-trial blocks could be explained by a latent "decision-making" factor within each of the three times of IGT…

The most common dating goals of adolescents are identity, intimacy, status and sex. In this study of Australian youth (16-30 years, N = 208), dating goals were expected to explain goal-consistent behavior in each domain. Also, goals coupled with consistent behavior were expected to be associated with greater satisfaction in each domain. Age,…

In this study the full array of personal goals pursued by adolescents was examined using an idiographic goal-elicitation procedure. The aims of the study were twofold. Firstly, we investigated individual differences in self-generated goals and goal process appraisals based on sociodemographic characteristics. Secondly, we investigated the…

Based on data from a 17-year longitudinal study of 1083 adolescents, from the ages of 13 to 30 years, the average development of self-reported global self-esteem was found to be high and stable during adolescence. However, there is considerable inter-individual variance in baseline and development of global self-esteem. This study used latent…

This study tested differences in personality traits measured by the Multidimensional Personality Questionnaire (MPQ) in a community sample of adolescents with definite or probable conduct disorder (CD) diagnoses that did not progress to a diagnosis of antisocial personality disorder (ASPD) by early adulthood (n=43), those with definite or probable…

Aims to provide a cross-cultural contribution to the study of gender differences in adolescent mood by providing results of a survey of Argentinian boys and girls at the age of 13-14, 15-16, and 17-18. The gender difference, larger than that of many first-world samples, is significant at 15-16 and the gap increases at 17-18. (Author)

The literature on participant roles in bullying lacks empirical studies that seek to explain what differentiates defenders from outsiders (or passive bystanders). The present study tested a conceptual model in which two personal characteristics of early adolescent students (empathy and perceived social self-efficacy) were considered as possible…

Past research has shown that the way people deal with religion is related to prejudice. Therefore, it is important to study the determinants of individual differences in adolescent religious attitudes. In the present study, it is proposed that both differences in personality and identity formation might determine these religious attitudes.…

Investigated to what extent imaginary companions are created in the diaries of adolescents. Content analysis of questionnaire responses by participants, ages 12 to 17 years (N=241), indicate that the imaginary companion was similar to the writer in many aspects. Results show that the imaginary companion was not the result of an egocentric…

Focused on subjective meanings of maturity in younger (6th grade) and older (9th grade) adolescents. Qualitative analysis revealed five images of maturity portrayed by adolescents: balanced maturity; privileges; responsibility; power and status; and physical development. There were some gender and age differences in frequencies of these images.…

Using a sample of 1227 Swedish adolescents we examined peer relations across contexts and for multiple peer targets (three ''Very Important Persons'', VIPs). Specifically, we examined the relations between antisocial behaviour and the types of relationships individuals had with their VIPs (e.g. friend, romantic partner), the contexts in which they…

The purpose of this study was to examine the linkages between alexithymia and delinquency in male adolescents (age ranging from 14 to 18 years), and to investigate whether alexithymia was a good discriminatory factor for juvenile delinquency. Thirty-six offender adolescents and 46 non-offender control adolescents participated in the study and…

In a study of adolescents in the 1970s, girls were high in normbreaking if they attended youth recreation centers "and" were heavily involved with peers or boys (Stattin et al., 2003). The present study investigated whether these results could be replicated on a modern sample, and then examined parent-child relationships and personality…
