A sample of serial stranger rape cases (n = 43)
Introduction Few studies have looked at prevalence estimates for female sexual dysfunctions in combination with personal distress, although existing diagnostic criteria for sexual disorders include both aspects. Further, the variation in female sexual function has been shown to be largely explained by unique nongenetic factors. Such factors may include partner sexual function and perception of sexual compatibility with a partner, factors which may also be associated with sexual distress. Aim We investigated the association between female sexual dysfunction and distress as well as their association with partner compatibility. Methods In order to assess sexual function and distress, the Female Sexual Function Index and seven items from the Female Sexual Distress Scale were used in a population-based sample of 5,463 women, aged 18–49 years. The women were, based on cutoff points, classified as either having neither dysfunction nor distress, one of them, or both, separately for each dysfunction. Further, the associations between partner compatibility, distress, and sexual dysfunctions were analyzed. Sexual compatibility with partner was investigated by using several items exploring, for example, amount of foreplay, interest in sex, and communication about sexual matters. Main Outcome Measures Associations between partner compatibility and female sexual function and sexual distress. Results The proportion of women reporting both sexual dysfunction and distress ranged from 7% to 23%, depending on the dysfunction. Desire disorders followed by orgasmic disorders were most common. All compatibility variables were significantly associated with distress and with most of the sexual dysfunctions. The main complaints of the women were “too little foreplay” (42%) and “partner is more interested” (35%). The women feeling distress or having a sexual dysfunction reported more incompatibility with partner compared with functional women. Conclusions The findings highlight the importance of addressing partner compatibility for successful treatment and counseling of female sexual dysfunctions.
A number (n = 27) of investigative interviews with children were analyzed with a view to explore the verbal dynamics between interviewer and child. Different types of interviewer utterances and child responses were defined, and the interrelationships between these were explored. The effectiveness of different interviewer utterances in eliciting information from children as well as the type of utterance the interviewer used to follow up an informative answer by the child were investigated. Option-posing and suggestive utterances made up for more than 50% of interviewer utterances, the proportion of invitations being only 2%. Invitations and directive utterances were associated with an increase in informative responses by the child, the adverse being true for option-posing and suggestive utterances. Interestingly, even after the child had provided an informative answer, interviewers continued to rely on focused and leading interviewing methods--in spite of a slight improvement in interviewing behavior.
A theoretical distinction between instrumental and expressive aggression was used in analyzing offender characteristics and their associations with crime scene actions in Finnish homicides. Twenty-one variables reflecting the offenders' criminal activity, previous relationships with intimates and victims, and general social and psychological adjustment were derived from files of single-offender/single-victim homicides occurring between 1980 and 1994 (n = 502). Additionally, three variables describing post-offense actions and police interview behavior were included. A multidimensional scaling procedure was used to investigate the interrelationships between the variables. A distinction between expressive and instrumental characteristics was observable in the empirical structure, which was divided into three subthemes of Instrumental, Expressive: Blood, and Expressive: Intimate. Associations between the characteristics with five previously identified subthemes of crime scene actions were computed. In addition, the subthemes of crime scene actions were related to post-offense actions and police interview behavior, with Expressive themes being associated with less denial as well as a greater likelihood of surrendering and confession. The practical usefulness for police investigations and theoretical implications of the results are discussed.
Introduction A number of different theoretical approaches to understanding the etiology of ejaculatory dysfunction have been proposed, but no behavior genetic study has yet, to our knowledge, been conducted to explore the genetic and environmental influences on ejaculatory dysfunction. Aim The aim of the present study was to explore the genetic and environmental effects on premature (PE) and delayed (DE) ejaculation in a population-based sample. Methods The genetic and environmental influences on PE and DE were investigated in a population-based sample of 1,196 Finnish male twins, age 33–43 years, with 91 identical and 110 complete twin pairs. Several different aspects of ejaculatory function were measured by a self-report questionnaire (e.g., latency time, subjective experience of ejaculatory control). Factor analyses distinguished two subcomponents of ejaculatory function, and subsequently, composite variables measuring PE and DE were created. Structural equation modeling was performed on the composite variables. Main Outcome Measures Measurement of genetic and environmental effects on PE and DE. Results The results suggested moderate genetic influence (28%) on PE, but not on DE (0%). There was a moderate familial effect on DE with shared environmental effects accounting for 24% of the variance. However, omission of the shared environmental component did not directly result in a significantly decreased model fit for DE, and omission of the additive genetic component did not directly result in a significantly decreased fit for the PE model. Conclusions The findings from the present study provide useful information regarding the etiology and understanding of ejaculatory dysfunction.
As measured with the Psychopathy Checklist-Revised (PCL-R), psychopathy is a dimensional construct underpinned by 4 correlated factors: Interpersonal, Affective, Lifestyle, and Antisocial. Theorists and clinicians (e.g., Karpman and Arieti) have posited 2 variants of "primary" or "true" psychopathy, both distinct from so-called "secondary" or "pseudopsychopathy." We used latent profile analysis to determine if homogeneous classes exist within a sample of 1,451 male offenders with high PCL-R scores (≥ 27). The 4 PCL-R factors were the dependent variables for clustering. A solution with 3 latent classes showed a better fit to the data than did a unitary model without latent classes. Tentative labels for the latent classes are Manipulative (Latent Class 1 [LC1]), Aggressive (Latent Class 2 [LC2]), and Sociopathic (Latent Class 3 [LC3]). The latter class represented an antisocial group that lacked the emotional detachment observed in the other 2 groups. We propose that LC1 and LC2 reflect phenotypic variations on a theme of the traditional construct of psychopathy, and that LC3 is consistent with conceptions of antisocial personality disorder and sociopathy. Replication and external classification with an independent data set of 497 adult male offenders again yielded clearly separable clusters, as well as meaningful differences or trends among latent classes on education, intelligence, symptoms of antisocial personality disorder, and self-reported psychopathic traits and negative affect. The conceptualization of psychopathy in terms of manipulative and aggressive variants is consistent with clinical theory and is empirically grounded.
Faces and bodies convey important information for the identification of potential sexual partners, yet clothing typically covers many of the bodily cues relevant for mating and reproduction. In this eye tracking study, we assessed how men and women viewed nude and clothed, same and opposite gender human figures. We found that participants inspected the nude bodies more thoroughly. First fixations landed almost always on the face, but were subsequently followed by viewing of the chest and pelvic regions. When viewing nude images, fixations were biased away from the face towards the chest and pelvic regions. Fixating these regions was also associated with elevated physiological arousal. Overall, men spent more time looking at female than male stimuli, whereas women looked equally long at male and female stimuli. In comparison to women, men spent relatively more time looking at the chests of nude female stimuli whereas women spent more time looking at the pelvic/genital region of male stimuli. We propose that the augmented and gender-contingent visual scanning of nude bodies reflects selective engagement of the visual attention circuits upon perception of signals relevant to choosing a sexual partner, which supports mating and reproduction.
The factor structure and reliability of the Female Sexual Function Index (FSFI) was evaluated in a Finnish population based sample of 2,081 women, age 33-43 years. In addition, associations between female sexual function and age, psychological distress, alcohol use, hormone based contraceptives, child sexual abuse (CSA), and adult sexual abuse were examined. The results supported a six factor solution for the FSFI with high internal consistencies, in line with earlier research in clinical populations. Psychological distress was positively associated with every dimension of the FSFI except desire problems. Age was associated with fewer pain problems. Alcohol use was associated with every dimension of the FSFI, but the direction of the association depended on if it was drinking in general or in connection to intercourse. More drinking in general was related to fewer sexual function problems while drinking in connection to intercourse was related to more sexual function problems. No significant correlation was found between adult sexual abuse and sexual function but between CSA and lubrication, satisfaction, and pain problems. Usage of oral contraceptive pill was not significantly associated with sexual function. The use of hormone based intrauterine systems was significantly associated with less pain and more desire, arousal, and satisfaction. In conclusion, the study supports use of the FSFI for assessing sexual function not only in clinical samples but also in population based samples. The associations found between sexual function and other important variables showed the complexity of sexual function.
