Predicting Different Patterns of Sexual Identity Development Over Time Among Lesbian, Gay, and Bisexual Youths: A Cluster Analytic Approach

Recent research has suggested that the sexual identity development of lesbian, gay, and bisexual (LGB) youths may not follow a single pattern, but may follow a variety of pathways. Although some research documenting variability in identity development exists, unclear are the potential individual and social contexts that predict these different patterns, as well as the contexts that predict changes in identity integration over time. This report longitudinally examined these issues in an ethnically diverse sample of 156 LGB youths (ages 14-21) in New York City. Cluster analytic techniques identified two patterns of sexual identity formation (i.e., early and more recent), and three patterns of sexual identity integration (i.e., high, middling, and low). Gender and sexual abuse were found to predict identity formation; and, gay-related stress, social support, negative social relationships, sexual orientation, sexual identity, and gender were found to predict patterns of sexual identity integration and changes in integration over 1 year. These findings document different patterns of sexual identity development and identify potential contextual barriers and facilitating factors that may be used to develop interventions to promote healthy LGB identity development.     

Dimensional analysis of a categorical diagnostic interview: the DICA-IV

The aim of this study is to obtain dimensions from a categorical diagnostic interview. 512 children aged 8 to 17 attending public centers for children's mental health and presenting some form of psychological disorder were interviewed with the "Diagnostic Interview for Children and Adolescents" (DICA-IV). Analysis of the principal components indicate that a two-dimensional model (externalizing-internalizing) satisfactorily explain the data collected from the children and their parents. The data from the adolescents are better represented by a three-dimensional model (attention problems-internalizing-antisocial behavior). The factor scales show good internal consistency and significantly relate to other criteria of psychopathology and incapacity (concurrent validity). These results show that it is possible to use DICA-IV to obtain categorical and dimensional indicators simultaneously. The latter are particularly sensitive for measuring changes over the course of disorders.     

The Small Worlds and Floyd's algorithms: a way to study scientific collaboration

Many proposals from the analysis of social networks focused on the study of scientific collaboration have been made recently. The Small Worlds theory seems to be the most efficient to study the inner features of the scientific community. Those researches have demonstrated that small communities are based on some key individuals who connect some groups which, on the contrary, would be disconnected. One of the disadvantages from the perspective of the analysis of networks is the lack of researches of particular nodes. With the implementation of a pseudocode algorithm of Floyd, we try to avoid this. To study how a small community is formed and, as a research of one case, we observe the invisible college which is formed when connecting the fifteen most productive authors of the Journal of Personality and Social Psychology .     

Subtypes of drug-addicts in treatment: empirical support for a distinction between Type A and Type B

This study examines the possibility of replicating and generalizing a multidimensional typology of drug-addicts by means of the evaluation of 320 participants who were receiving outpatient treatment for their problem of addiction. A two-stage cluster analysis was performed, revealing the existence of two typologies of consumers, called type A and Type B. The participants classified as Type B showed various indicators of chronicity (higher mean age, higher unemployment rate), more severity of their problem of drug consumption and of medical aspects, employment support, legal, family/social and psychiatric problems in comparison with Type A. Participants from the latter group reported active employment as their main source of income and they had consumed drugs for fewer years. However, they presented more severity associated with alcohol consumption. In view of these data, Type A is called functional drug-addict and Type B chronic drug-addict. Once the groups of drug-addicts were delimited, a more specific characterization was made, taking seven problem areas into account: medical, employment support, alcohol, drugs, legal, family/social, and psychiatric areas. As a general conclusion, more psychosocial severity was observed in Type B as compared with Type A. Lastly, the implications and usefulness of grouping drug-addicts into typologies is discussed.     

Further examination of measurement properties of Spanish version of the Sexual Desire Inventory with undergraduates and adolescent students

The factor structure and construct validity of a Spanish version of Spector, Carey, and Steinberg's Sexual Desire Inventory was examined with structural equation modelling and a nonclinical sample (N = 608). Confirmatory factor analysis indicated that Dyadic and Solitary sexual desire scales measured two factorially distinct constructs. Their internal consistency reliabilities were .87 and .88, respectively. Structural equation analysis indicated that both subscales are distinguishable from similarly conceptualized correlates of sexual desire: the Impersonal subscale of the Sex Fantasy Questionnaire and the Erotophilia measure of the Sexual Opinion Survey. However, the data raised some questions about an empirical distinction between dyadic sexual desire and intimate sexual fantasy.
