Study protocol: implementing and evaluating a trauma-informed model of care in residential youth treatment for substance use disorders.

Introduction: Comorbidity between Substance Use Disorders and trauma/post-traumatic stress disorder (PTSD) is common, particularly within residential treatment services. Comorbidity is associated with poorer treatment retention and treatment outcomes. Integrated treatment approaches are increasingly recommended but are still under examined in residential treatment services. This study will implement and evaluate a novel model of trauma-informed care (TIC) in a youth (18-35 years) residential substance use treatment service. Methods and analysis: A single-armed, phase 1 implementation trial will be conducted in one residential treatment service. The model, co-developed with staff, incorporates: (i) workforce development in TIC through staff training and clinical supervision; adaptions to the service (ii) policies, procedures, and physical settings and (iii) treatment program adaptions (in delivery style and content) to be more trauma-informed; (iv) client screening and feedback for trauma and PTSD at service entry; and (v) the provision of support, referral and/or trauma-focused therapy to those with PTSD. Service outcomes will include adherence to the TIC model and client treatment completion. Client substance use and mental health measures will be collected at service entry, and 1-, 3-, 6- and 12-months follow up. Staff outcomes, including workplace satisfaction, burnout, and fatigue, as well as perceptions and confidence in delivering TIC will be collected at baseline, and at 3-, 6-, 12- and 18-months following training in the model. The sustainability of the delivery of the TIC model of care will be evaluated for 12 months using service and staff outcomes. Ethics and dissemination: The study has received ethical approval by the University of Queensland (Approval number: 2020000949). The results will be disseminated through publication in a peer-reviewed scientific journal, presentations at scientific conferences, and distributed via a report and presentations to the partner organization.Clinical trial registration: ACTRN12621000492853.

Client and staff perceptions of the integration of trauma informed care and specialist posttraumatic stress disorder treatment in residential treatment facilities for substance use: A qualitative study.

INTRODUCTION: Comorbid posttraumatic stress disorder (PTSD) is prevalent among people seeking residential treatment for substance use disorders (SUD). We examined client and staff perceptions of the relationship between trauma and SUDs, and the integration of trauma-informed care (TIC) and specialist-delivered treatment for PTSD in residential alcohol and other drug (AOD) treatment facilities. METHODS: Individual semi-structured interviews were conducted with frontline staff (n = 20) and clients (n = 18) in two residential AOD treatment facilities in Queensland, Australia. Interviews were audio recorded, transcribed and shared client and staff data was analysed using thematic analysis. RESULTS: Major staff and client themes emerged: PTSD was perceived as an underlying cause of SUD, where AOD is used to cope with and avoid PTSD and related symptoms (Theme 1). Residential facilities were perceived to provide a safe and supportive environment for clients (Theme 2). Psychoeducation on SUD and PTSD was also highlighted to normalise experiences associated with comorbid SUD/PTSD and promote help-seeking pathways for specialist PTSD treatment. Concurrent treatment of SUD and PTSD in the residential setting was sought after and was perceived to enhance treatment outcomes (Theme 3). Staff saw the need for implementing TIC into the organisation and perceived TIC as a multi-faceted and consistent approach of service delivery. DISCUSSION AND CONCLUSIONS: Both clients and staff perceive comorbid SUD/PTSD as a challenge in residential treatment, that may be overcome through integrating TIC and PTSD treatment in residential treatment facilitates for substance use. Organisational and practical implications are discussed.

Student perceptions of the current drinking culture in three Australian residential colleges: Drinking motives, consequences and recommendations for harm minimisation strategies.

INTRODUCTION: Systemic cultural factors related to excessive alcohol consumption have been identified in Australian university residential colleges. In this mixed methods study, we conducted focus groups with student leaders at three Australian residential colleges. We aimed to explore students' perceptions of alcohol use and related consequences in their current college environment and gather feedback from students on the utility of alcohol harm minimisation strategies in this context. METHODS: In November 2020, 77 student leaders from three colleges participated in focus groups. Each focus group ran for 1.5-2 hours and included three sections: (i) quantitative survey; (ii) semi-structured group interview; and (iii) feedback on a potential alcohol harm minimisation workshop. RESULTS: The survey revealed that 81% of participants reported drinking hazardously. Thematic analysis of the interview data indicated many students perceived college as a supportive environment regarding students' alcohol use choices (direct peer pressure to drink was uncommon). However, indirect social influence to drink appeared to maintain a 'culture of intoxication'. Specifically, social norms to attend college events (where drinking is implied) and modelling of excessive drinking were key indirect influences on heavy drinking norms. Students were aware and accepting of many alcohol harm minimisation strategies and interested in improving current strategies. DISCUSSION AND CONCLUSIONS: Despite the supportive college environment described by students, regarding alcohol use choices, a 'culture of intoxication' driven by indirect social influences was evident. Student leaders' interest in increasing the availability of harm minimisation strategies highlights the potential utility of peer-led alcohol interventions in colleges.

Polysubstance use in young people accessing residential and day-treatment services for substance use: substance use profiles, psychiatric comorbidity and treatment completion.

BACKGROUND AND AIMS: People with substance use disorders (SUDs) frequently present to treatment with polysubstance use and mental health comorbidities. Different combinations of substance use and mental health problems require different treatment approaches. Our study aimed to: (i) identify the shared substance use classes among young people at treatment admission, (ii) determine which mental health symptoms, quality of life (QoL) and service types were associated with the identified substance use classes, and (iii) prospectively determine which substance use classes and service types were more likely to complete treatment. DESIGN: Cross-sectional and prospective study using service and outcome data. SETTING: Substance use treatment services in Queensland and New South Wales, Australia. PARTICIPANTS: De-identified service and outcome measure data were extracted from the files of 744 clients aged 18-35 years (48% male) admitted into seven residential and four day-treatment programmes. MEASUREMENTS: Substance use and severity among tobacco, alcohol, cannabis, cocaine, amphetamine-type stimulants, opioids, sedatives and inhalants. Other variables included: depression, anxiety, post-traumatic stress and psychotic symptoms, as well as QoL. FINDINGS: Latent class analysis identified three polysubstance use classes: wide-ranging polysubstance users (WRPU; 22.45%), primary amphetamine users (56.45%) and alcohol and cannabis users (21.10%). The WRPU class had higher odds of psychotic symptoms than the alcohol and cannabis use class [odds ratio (OR) = 1.30; 95% confidence interval (CI) = 1.11-1.11]; and double the odds of residential programme enrolment than those in the amphetamine use class (OR = 2.35; 95% CI = 1.50-3.68). No other class differences on mental health or QoL variables were found. Clients enrolled in day-programmes had higher odds of completing treatment. CONCLUSIONS: There appear to be high levels of polysubstance use among young people entering substance use treatment in Australia. Wide-ranging polysubstance users were more likely to report psychotic symptoms and be enrolled into a residential programme than primary amphetamine users and alcohol and cannabis users.

A multivariate analysis of women's mating strategies and sexual selection on men's facial morphology.

The strength and direction of sexual selection via female choice on masculine facial traits in men is a paradox in human mate choice research. While masculinity may communicate benefits to women and offspring directly (i.e. resources) or indirectly (i.e. health), masculine men may be costly as long-term partners owing to lower paternal investment. Mating strategy theory suggests women's preferences for masculine traits are strongest when the costs associated with masculinity are reduced. This study takes a multivariate approach to testing whether women's mate preferences are context-dependent. Women (n = 919) rated attractiveness when considering long-term and short-term relationships for male faces varying in beardedness (clean-shaven and full beards) and facial masculinity (30% and 60% feminized, unmanipulated, 30% and 60% masculinized). Participants then completed scales measuring pathogen, sexual and moral disgust, disgust towards ectoparasites, reproductive ambition, self-perceived mate value and the facial hair in partners and fathers. In contrast to past research, we found no associations between pathogen disgust, self-perceived mate value or reproductive ambition and facial masculinity preferences. However, we found a significant positive association between moral disgust and preferences for masculine faces and bearded faces. Preferences for beards were lower among women with higher ectoparasite disgust, providing evidence for ectoparasite avoidance hypothesis. However, women reporting higher pathogen disgust gave higher attractiveness ratings for bearded faces than women reporting lower pathogen disgust, providing support for parasite-stress theories of sexual selection and mate choice. Preferences for beards were also highest among single and married women with the strongest reproductive ambition. Overall, our results reflect mixed associations between individual differences in mating strategies and women's mate preferences for masculine facial traits.
