Understanding service users’ and therapists’ experiences of pharmacological treatment for sexual preoccupation and/or hypersexuality in incarcerated sex offenders

This research comprises two qualitative studies understanding the experiences of (1) convicted sex offenders voluntarily receiving pharmacological treatment to reduce sexual preoccupation and (2) therapists working with these offenders. The studies form part of a research programme evaluating the use of pharmacological treatment with sexual offenders. In study one, semi-structured interviews were conducted with 13 sexual offenders receiving selective serotonin reuptake inhibitors. In study two, interviews were conducted with eight intervention staff with varying levels of experience of working with offenders taking anti-libidinals. Thematic analysis was used and in study one, two main themes emerged: (i) the impact of the pharmacological treatment on prisoners’ daily functioning; (ii) barriers to compliance/engagement. In study two, three main themes emerged: (i) offenders’ reluctance to engage with pharmacological treatment; (ii) challenges for therapists; (iii) pharmacology: ‘just another piece of the puzzle’. Findings are discussed in relation to practice and future research.     

Auto Theft and Restrictive Deterrence

Although researchers have examined the attributes that make offenders more or less responsive to sanction threats, far less attention has centered on the manner in which responsiveness can lead to less detectible crime, or perhaps even more overall crime. Restrictive deterrence is the concept that explains this paradox. We explore it here using qualitative interviews with 35 active auto thieves. Findings suggest that auto thieves' restrictively deterrent decision-making strategies fell into three broad categories: discretionary target selection, normalcy illusions, and defiance. Discussion focuses on the data's conceptual implications for restrictive deterrence and offender decision-making.

Living in the demos: qualitative approaches to demographic questions

Contributors to this special issue use qualitative methodologies to explore questions traditionally posed by demographers. The introduction summarizes each article and surveys the wider potential significance of qualitative research for historical demography. The authors suggest that this research can disrupt traditional scholarly categories and methods pertaining to reproduction and other demographic phenomena. Qualitative sources may serve as wild cards suggesting new paths of investigation based on individuals' idiosyncratic viewpoints; but they may also offer ways to collapse and integrate wide bodies of knowledge by contextualizing and reframing the blurred cross-categorical world views associated with individuals' actionable ideas and ideals. Studying such views more systematically will become easier as the digitization of human culture, past and present, proceeds apace. Moreover, as digital tools for accessing and interpreting text become more sophisticated, individual- and aggregate-level studies may be increasingly understood as a single scholarly corpus, rather than two parallel approaches with scattered mutual intelligibility and intermittent cross-fertilization. As explanations for fertility decline continue to center on modernization – often without speaking its name – the authors suggest that individual narratives offer a way to subjectivize modernization while avoiding the mystical incoherence of extreme subjectivization.     

Identities,Boundaries, and Accounts of Women Methamphetamine Users

Drug users often define themselves as functional users and depict others as dysfunctional (i.e. junkies). Previous research on the social identities of drug users has focused on the symbolic boundaries they create to distance themselves from stigmatized others. Investigators have yet to focus on how users account for their own boundary violations. Here, we examine the narratives of 30 former women methamphetamine (meth) users to determine how they make distinctions between functional and dysfunctional meth users (i.e. “meth heads”). The distinctions they make are based on users’ abilities to maintain control of their lives and to hide their use from outsiders. Those who saw themselves as functional but who engaged in behaviors inconsistent with this image accounted for these behaviors to maintain desired identities. We show the complexity of drug users’ identities and illustrate how anti-drug campaigns that provide grotesque caricatures of drug users may prolong drug using careers.     

Expressions of Culture in American Indian/Alaska Native Tribal Child Welfare Work: A Qualitative Meta-Synthesis

This qualitative meta-synthesis of materials from three national projects that had examined more than 75 American Indian/Alaska Native child welfare programs sought to articulate how culture is expressed within tribal child protective services (CPS)work and to uncover whether there are cultural elements of tribal child welfare practice that are distinct from practice in non-tribal settings. Through the meta-synthesis, a framework emerged outlining a cultural approach to practice that incorporates: (a) a culturally-distinct definition of Native child well-being; (b) tribal values that form a foundation for practice; (c) practice intentions linking child protection with cultural and community health; and (d) two specialized worker skills.     

Domestic violence and high conflict are not the same: a gendered analysis

In child custody decision-making experiences of domestic violence and high conflict are not the same. Legislative reform has not yet been guided by the parent voice to inform differentiated responses that keep women and children safe. Available literature in child custody decision-making focuses on outcome research regarding children’s adjustment and well-being. Debates about types of post-separation arrangements have yet to find agreement in three under-researched areas: (a) high conflict, (b) domestic violence; and (c) children under four. Yet, Canadian legislation supports shared parenting arrangements that privilege the dominant, powerful parent in situations of domestic violence. Based on a Canadian study that explores the parent perspectives and experiences of child custody decision-making, this paper privileges a sub-group of participants; five women, all survivors of domestic violence; defined here as both physical violence and coercive control. Data collection includes one-on-one tape-recorded interviews. Thematic analysis reveals that shared parenting is neither the goal, nor does it meet the needs of these women. The findings illuminate the importance of differentiating parent experience as distinct groups, and reinforces the notion of the state’s role in the reproduction of gendered power. Legislative reform and collaborative community practices are critical to facilitate healthy differentiated responses.
