Psychotic disorders often have been linked with violence. However, studies have shown that people with a psychotic disorder are more often victim than perpetrator of violence. The objective of this meta-analysis was to review prevalence rates for different types of victimization and to identify risk factors associated with victimization. Based on a search in MEDLINE, PsycINFO, and Web of Science, 27 studies were found with samples consisting of adults with a psychotic disorder and possible victimization occurring during adulthood and data on "violent victimization," "sexual victimization," "non-violent victimization," and/or "victimization not otherwise specified...

Substance-related and behavioral addictions are extremely prevalent and represent a major public health concern. In the ongoing attempt to understand the addictive personality, contradictory results have arisen from studies that have explored personality traits in different addiction populations. The diversity across addiction types suggests that some of these inconsistencies stem from distinct personalities underlying each addiction. The present study compares the personality profiles of several addictions, representing both substance (drugs and alcohol) and behavioral (gambling and sex) subtypes...

This study aimed to assess the prevalence and correlates of condom use at last sexual intercourse among people aged 15-49 years in Nepal. Secondary data analysis was performed using the Nepal Demographic and Health Survey 2011. The study was restricted to the respondents who reported ever having had sexual intercourse; 9843 females and 3017 males were included. Condom use was assessed by asking if respondents used condoms in their most recent sexual intercourse. Chi-square test and multivariate logistic regression analysis were performed using Complex Sample Analysis Procedure to adjust for sample weight and multistage sampling design...

The U.S. Centers for Disease Control and Prevention (CDC) Diffusion of Effective Behavioral Interventions project has disseminated HIV behavioral interventions (EBIs) across the United States since the 1990s. In 2011, the CDC launched the High-Impact HIV Prevention (HIP) project, providing EBIs plus high-impact services (HIV testing, primary care, and support services). Providers (nurses, social workers, educators) are unable to consistently make linkages; thus, numerous at-risk individuals are not benefitting from HIP...

The International Society for the Study of Women's Sexual Health process of care (POC) for management of hypoactive sexual desire disorder (HSDD) algorithm was developed to provide evidence-based guidelines for diagnosis and treatment of HSDD in women by health care professionals. Affecting 10% of adult females, HSDD is associated with negative emotional and psychological states and medical conditions including depression. The algorithm was developed using a modified Delphi method to reach consensus among the 17 international panelists representing multiple disciplines...

From a psychological perspective, the menstrual cycle has been a research topic for more than 50 years. The most recent menstrual cycle research has been driven by an increased interest in sex differences in neuroscience, and the urge to understand sex disparities in prevalence, clinical presentation, and treatment response in psychiatric or neurologic disorders. Indeed, the menstrual cycle is an excellent model of ovarian steroid influence on emotion, behavior, and cognition. This review summarizes the emotion-related and cognitive findings of methodologically sound menstrual cycle studies...

Youth involved in the juvenile justice system represent a medically underserved population. Recidivist youth have poorer health outcomes compared to youth detained for the first time. This study determined differences in immunization history, substance use, mental health symptoms, and sexual behavior between recidivist youth and first-time detainees following improvements in intake screenings at a large, urban juvenile detention center in the Southeastern United States. Multivariable logistic regression analysis found that recidivist youth had significantly higher acellular pertussis immunization rates compared with first-time detainees (odds ratio [ OR] = 3...

BACKGROUND: Adolescent compulsive sexual behavior (CSB), and its associations with other personality predispositions (attachment orientations, temperament), gender, religiosity, and psychopathological tendencies. Five alternative empirical models were examined, all based on current theory and research on CSB. METHODS: The sample include 311 high-school adolescents (184 boys, 127 girls) ranging in age from 16 to 18 (M  = 16.94, SD  = .65) and enrolled in the eleventh (43...

Early life trauma (ELT) may increase the risk towards bipolar disorder (BD) and major depression (MDD), disorders associated with activated neuro-oxidative and neuro-nitrosative stress (O&NS) pathways. It has remained elusive whether ELTs are associated with O&NS and which ELTs are associated with distinct affective disorder phenotypes. This case-control study examined patients with BD (n = 68) and MDD (n = 37) and healthy controls (n = 66). The Child Trauma Questionnaire (CTQ) was used to assess specific ELT...

Cuticular hydrocarbons (CHCs) play an important role as contact pheromones in insects, particularly in flies. However, for many fly taxa our understanding of the importance of CHCs in sexual communication is limited. Within the family Calliphoridae (blowflies), sex-specific differences in CHCs have been reported for several species, but there is no evidence that CHCs facilitate sexual behavior. In order to elucidate the function of CHCs in Calliphoridae, studies combining behavioral and chemical analyses are required...

Addiction is the term employed not only for excess consumption of substances, but also for problem behaviours like eating disorders, pathological gambling, computer addiction and pathological preoccupation with video games and sexual acts. No clear diagnostic criterion has been established with validity for behavioral addictions. Sexual addiction, including addiction to pornography is not included as a separate entity because of a lack of strong empirical evidence in this area. Different scales can be used for assessment of sexual addiction...

Background: HIV disproportionately affects sexual minority men, and developing strategies to reduce transmission risk is a public health priority. Purpose: The goal was to empirically test a newly developed, Information, Motivation, Behavioral skills (IMB) theoretically derived, online HIV sexual risk reduction intervention (called HINTS) among a sample of sexual minority men living with HIV. Methods: Participants were 167 men randomized to either the four-session online HINTS intervention or to a time-matched, online control condition...

OBJECTIVES: The increase in HIV transmissibility in non-ulcerative sexually transmitted infection is already well-established. It is estimated that symptomatic carriers of N. gonorrhoeae and C. trachomatis have a relative risk of 4.8-fold and 3.6-fold, respectively, for the sexual acquisition of HIV. This type of evaluation for asymptomatic urethritis is necessary to reinforce strategies to combat HIV transmission. This study aims to assess the prevalence of patients with asymptomatic urethritis among men diagnosed with HIV-1 and determine the risk factors associated with this infection...

One main source of sexual socialization lies within family interactions. Especially sexuality-specific parenting may determine adolescents' sexual development-adolescents' sexual behavior and sexual risk behavior, sexualized media consumption and permissive sexual attitudes-to a significant extent, but different ideas exist about how this works. In this longitudinal study, we examined two hypotheses on how sexuality-specific parenting-parenting aimed specifically at children's sexual attitudes and behaviors-relates to adolescents' sexual development...

Facultative reproductive strategies that incorporate both sexual and parthenogenetic reproduction should be optimal, yet are rarely observed in animals. Resolving this paradox requires an understanding of the economics of facultative asexuality. Recent work suggests that switching from parthenogenesis to sex can be costly and that females can resist mating to avoid switching. However, it remains unclear whether these costs and resistance behaviors are dependent on female age. We addressed these questions in the Cyclone Larry stick insect, Sipyloidea larryi , by pairing females with males (or with females as a control) in early life prior to the start of parthenogenetic reproduction, or in mid- or late life after a period of parthenogenetic oviposition...

While the literature on sexual scripts is substantive, with some scholarship examining the role of popular media in the production of dominant and divergent sexual practices and interactions, limited attention has been paid to the contemporary Mexican context. In this article, we share findings from a quantitative content analysis of popular Mexican films in order to explore how sexual behavior is portrayed and more specifically how relationship characteristics, condom use, and substance use interact with representations of sexual behavior...

Transcriptional control of oxytocinergic cell development influences social, sexual, and appetite related behaviors, and is implicated in disorders such as autism and Prader-Willi syndrome. Mediator 12 (Med12) is a transcriptional coactivator required for multiple facets of brain development including subsets of serotonergic and dopaminergic neurons. We surveyed hormone gene expression within the hypothalamo-pituitary axis of med12 mutant zebrafish embryos with a focus on oxytocin ( oxt ) expression. Some transcripts, such as oxt , vasopressin ( avp ) and corticotrophin releasing hormone ( crh ) are undetectable in the med12 mutant, while others are upregulated or downregulated to varying degrees...

BACKGROUND: Child sexual abuse and neglect have been related to an increased risk for the development of a wide range of behavioral, psychological, and sexual problems and increased rates of suicidal behavior. Contrary to the large amount of research focusing on the negative mental health consequences of child sexual abuse, very little is known about the characteristics of child sexual offenders and the neuronal underpinnings contributing to child sexual offending. METHODS AND SAMPLE: This study investigates differences in resting state functional connectivity (rs-FC) between non-pedophilic child sexual offenders (N = 20; CSO-P) and matched healthy controls (N = 20; HC) using a seed-based approach...

BACKGROUND: Sexual and gender-based violence (SGBV) remains a silent epidemic in many humanitarian settings with many survivors concealing their experiences. Attitudes towards help-seeking for SGBV is an important determinant of SGBV service use. This paper examined the association between attitudes towards seeking care and knowledge and perceptions about SGBV among men and women in a humanitarian setting in Uganda. METHODS: A cross-sectional survey was conducted from May to June 2015 among 601 heads of refugee households (261 females and 340 males) in Rwamwanja Refugees Settlement Scheme, South West Uganda...
