This paper describes the diversity of family forms within a sample of 455 families parented by same-sex couples and same-sex attracted sole parents from Australia and New Zealand. Around one-third of this sample had conceived at least one of their children while in a previous heterosexual relationship. The remaining two-thirds had conceived at least one child within a same-sex relationship or while they were single. Among this group, the largest proportion was women who conceived using home-based self-insemination with a known donor. A smaller proportion of women had conceived through clinic-based insemination or assisted reproduction with a known or unknown donor. There were 60 male participants in the sample. Around 20% of these men were raising children they had conceived through a surrogacy arrangement; the rest had conceived their children within previous heterosexual relationships or through donor arrangements with single women or lesbians. Around 50% of participants described their family form in terms of a two-parent model, where they and their partner were their children's only parents. Around 34% were sharing care of their children with ex-partners, either a previous heterosexual (opposite sex) partner or a previous same-sex partner. Around 10% described themself as their child's sole parent. In large part, participants in this study were not creating radically new family formations, with around half of all participants describing their family in terms of a two-parent ‘nuclear’ model, albeit a model involving parents of the same gender. However, pathways to conception and/or parenthood did reflect nontraditional patterns.

Background: While families headed by same-sex couples have achieved greater public visibility in recent years, there are still many challenges for these families in dealing with legal and community contexts that are not supportive of same-sex relationships. The Work, Love, Play study is a large longitudinal study of same-sex parents. It aims to investigate many facets of family life among this sample and examine how they change over time. The study focuses specifically on two key areas missing from the current literature: factors supporting resilience in same-sex parented families; and health and wellbeing outcomes for same-sex couples who undergo separation, including the negotiation of shared parenting arrangements post-separation. The current paper aims to provide a comprehensive overview of the design and methods of this longitudinal study and discuss its significance.
Methods/Design: The Work, Love, Play study is a mixed design, three wave, longitudinal cohort study of same-sex attracted parents. The sample includes lesbian, gay, bisexual and transgender parents in Australia and New Zealand (including single parents within these categories) caring for any children under the age of 18 years. The study will be conducted over six years from 2008 to 2014. Quantitative data are to be collected via three on-line surveys in 2008, 2010 and 2012 from the cohort of parents recruited in Wave1. Qualitative data will be collected via interviews with purposively selected subsamples in 2012 and 2013. Data collection began in 2008 and 355 respondents to Wave One of the study have agreed to participate in future surveys. Work is currently underway to increase this sample size. The methods and survey instruments are described.
Discussion: This study will make an important contribution to the existing research on same-sex parented families.
Strengths of the study design include the longitudinal method, which will allow understanding of changes over time within internal family relationships and social supports. Further, the mixed method design enables triangulation of qualitative and quantitative data. A broad recruitment strategy has already enabled a large sample size with the inclusion of both gay men and lesbians.

Research has suggested that child sex offenders hold thematically distinct cognitive distortions, which Ward and Keenan (1999) call Implicit Theories. The aim of this preliminary study was to investigate the relationship between offenders’ Implicit Theories and their personality related cognitions. The variables were measured using the Implicit Theory Questionnaire and Millon’s (1990) MCMI-III personality scales. Subjects were 28 male sex offenders against children serving a custodial sentence in New Zealand, who elected to participate in a treatment program. A majority of participants had personality scale scores that reached the clinical threshold. Results found that dependant, depressive and schizoidal personality patterns significantly correlated with Implicit Theories. Clinical and theoretical implications are discussed.

The current generation of community protection laws represents a shift in priorities that may see the individual rights of sex offenders compromised for the goal of public safety. At the center of many judicial decisions under these laws are the risk assessment reports provided by mental health practitioners. The widespread enactment of laws allowing for additional sanctions for sex offenders, and a burgeoning research literature regarding the methods used to assess risk have served to heighten rather than resolve the ethical concerns associated with professional practice in this area. This article examines ethical issues inherent in the use of two assessment methods commonly used with sex offenders in the correctional context, focusing on actuarial measures and polygraph tests. Properly conducted and adequately reported actuarial findings are considered to provide useful information of sufficient accuracy to inform rather than mislead judicial decision makers, although careful consideration must be given to the limitations of current measures in each individual case. Despite its increasing use, polygraph testing is considered controversial, with little consensus regarding its accuracy or appropriate applications. On the basis of the current state of the professional literature regarding the polygraph, its use with sex offenders raises unresolved ethical concerns.

Although females represent a small proportion of the sex offender population, they occasionally appear before the courts under the current generation of laws intended to protect the public from high-risk sex offenders. In this context, practitioners are called upon to provide assessment of the risk these women pose for sexual re-offending. The primary issues addressed in this paper are related to the validity of conducting such risk assessments and providing professional opinions as to the risk of further sexual offences that may be committed by female offenders. The approach taken is to summarize briefly the available professional literature regarding female sex offenders, and then to present the findings of the relatively few empirical studies that address sexual recidivism in females. The final section examines the positions taken in the published works of various international experts regarding risk assessment with females, followed by conclusions and recommendations in light of the standards typically prescribed by community protection laws.

A useful understanding of the relationship between age, actuarial scores, and sexual recidivism can be obtained by comparing the entries in equivalent cells from “agestratified” actuarial tables. This article reports the compilation of the first multisample age-stratified table of sexual recidivism rates, referred to as the “multisample age-stratified table of sexual recidivism rates (MATS-1),” from recent research on Static-99 and another actuarial known as the Automated Sexual Recidivism Scale. The MATS-1 validates the “age invariance effect” that the risk of sexual recidivism declines with advancing age and shows that age-restricted tables underestimate risk for younger offenders and overestimate risk for older offenders. Based on data from more than 9,000 sex offenders, our conclusion is that evaluators should report recidivism estimates from age-stratified tables when they are assessing sexual recidivism risk, particularly when evaluating the aging sex offender.

One way to characterise the Rudd Government’s first year in office would be by the flurry of inquiries and reports that it commissioned. Three related to gender equality. The Productivity Commission conducted an inquiry into a national paid maternity, paternity and parental leave scheme and the House of Representatives Standing Committee on Employment and Workplace Relations conducted an inquiry into pay equity. This article is concerned with a third inquiry — the Senate Standing Committee on Legal and Constitutional Affairs (the committee) inquiry into the effectiveness of the Sex Discrimination Act 1984 (Cth) (SDA) in eliminating discrimination and promoting gender equality. These inquiries were not the Rudd Government’s only activities in relation to sex discrimination and gender equality. It also enacted legislation which removed discrimination against same sex couples from 68 Commonwealth laws and announced its intention to accede to the Optional Protocol to the International Convention on the Elimination of All Forms of Discrimination against Women.

Little is known of the extent to which heterosexual couples are satisfied with their current frequency of sex and the degree to which this predicts overall sexual and relationship satisfaction. A population-based survey of 4,290 men and 4,366 women was conducted among Australians aged 16 to 64 years from a range of sociodemographic backgrounds, of whom 3,240 men and 3,304 women were in regular heterosexual relationships. Only 46% of men and 58% of women were satisfied with their current frequency of sex. Dissatisfied men were overwhelmingly likely to desire sex more frequently; among dissatisfied women, only two thirds wanted sex more frequently. Age was a significant factor but only for men, with those aged 35-44 years tending to be least satisfied. Men and women who were dissatisfied with their frequency of sex were also more likely to express overall lower sexual and relationship satisfaction. The authors' findings not only highlight desired frequency of sex as a major factor in satisfaction, but also reveal important gender and other sociodemographic differences that need to be taken into account by researchers and therapists seeking to understand and improve sexual and relationship satisfaction among heterosexual couples. Other issues such as length of time spent having sex and practices engaged in may also be relevant, particularly for women.
