Meta-Analyses of Fraternal and Sororal Birth Order Effects in Homosexual Pedophiles, Hebephiles, and Teleiophiles.

This study investigated the relations between numbers of older brothers, numbers of older sisters, and the odds of homosexuality in later-born males, including males who are most attracted sexually to prepubescent or early pubescent children (pedohebephiles) and males who are most attracted sexually to adults (teleiophiles). The authors meta-analyzed data from 24 samples of homosexual and heterosexual men, originally reported in 18 studies, and totaling 18,213 subjects. The results confirmed that older brothers increase the odds of same-sex preference in pedohebephiles as they do in teleiophiles.

[The Measurement of Psychological Mindedness: a validation study of the German version of the Balanced Index of Psychological Mindedness (BIPM)].

The aim of the study is to examine central measurement properties of the translated Balanced Index of Psychological Mindedness (BIPM) within a sample of German native speakers. Factor structure, validity and reliability of the BIPM was examined using data from a community sample of 399 participants. Additionally, associations between BIPM and socio-demographic variables were tested.

A method yielding comparable estimates of the fraternal birth order and female fecundity effects in male homosexuality.

The fraternal birth order effect (FBOE) is the finding that older brothers increase the probability of homosexuality in later-born males, and the female fecundity effect (FFE) is the finding that the mothers of homosexual males produce more offspring than the mothers of heterosexual males. In a recent paper, Khovanova proposed a novel method for computing independent estimates of these effects on the same samples and expressing the magnitude and direction of the effects in the same metric. In her procedure, only families with one or two sons are examined, and daughters are ignored.

[Validation of the German Version of the Psychological Mindedness Scale (PMS-D)].

Unlabelled: Validation of the German Version of the Psychological Mindedness Scale (PMS-D) Objectives: The Psychological Mindedness Scale (PMS) is one of the few established measures for psychological mindedness (PM). PM refers to a capacity and disposition to properly perceive inner processes - feelings, thoughts and conflicts. The aim of this study was the validation of the German translation of the PMS, which was conducted via TRAPDprocess.

Stability of Self-Reported Arousal to Sexual Fantasies Involving Children in a Clinical Sample of Pedophiles and Hebephiles.

In forensic research, there is a controversial discussion concerning the changeability or stability of pedophilia. Seto (2012) conceptualized pedophilia as a sexual age orientation characterized by an early onset, correlations with sexual and romantic behavior, and stability over time. However, empirical data are sparse and are mostly based on samples of detected offenders.
