Research indicates a robust association between personality and substance use and misuse. The high prevalence and pervasive detrimental impacts of alcohol use disorder (AUD) and smoking of tobacco necessitate more studies designed to identify factors closely associated with these outcomes in specific populations. The analyses reported in the present paper concern the relative utilities of five measures of personality and personality pathology rated by three sources (self, informant, and interviewer) in predicting AUD and regular smoking in a representative sample of 987 older adults, an understudied and uniquely vulnerable population. All measures and sources contributed to the predictions, with notable parallels as well as some important differences identified across substances and sources of information. In particular, low agreeableness robustly predicted AUD and smoking across self- and informant-reports. High interviewer-rated borderline personality pathology also strongly predicted AUD. Model fit indices suggested that measures of personality and personality pathology have stronger utility in predicting AUD as compared to regular smoking. These findings have important implications for the assessment of older adults in research and clinical settings and for the understanding of enduring risk factors for substance misuse later in life. Multi-source personality information is valuable for generating a complete picture of the relationship between personality and substance misuse.

Within the last decade, there has been a sharp global rise in the number of young people identifying as transgender. More recently, there appears to be an increase in the numbers of young people detransitioning or returning to identifying with their natal sex after pursuing medical transition. A case is presented of a young woman who pursued a gender transition and returned to identifying as female after almost two years on testosterone. The author considers and critiques the affirmative model of care for gender dysphoric youth in light of this case.  相似文献

Approximately half of mothers receiving substance use treatment are involved with childcare proceedings. This review aims to determine whether integrated treatment programmes for mothers with substance use problems are effective in preventing out-of-home placement (temporally/permanent) and influencing other maternal factors such as patterns of substance use, treatment completion and parenting behaviours. Six trials were identified—two randomised controlled trials and four non-randomised controlled studies. The pooled sample of participants was 1717. The results showed that mothers who participated in integrated treatment programmes were significantly less likely to have the children removed from their care (Odds Ratio (OR)?=?0.40, 95% CI?=?0.27, 0.61), more likely to complete substance use treatment (OR?=?3.01, 95% CI?=?1.79, 5.06), and more likely to reduce their alcohol consumption (Standardised Mean Difference (SMD)?=??0.40, 95% Cl?=??0.78, ?0.01) and drug use (SMD?=??0.30, 95% CI?=??0.53, ?0.07). However, non-significant reductions were observed for parent–child conflict (SMD?=??0.35, 95% CI?=??0.72, 0.03) and child abuse risk (SMD?=??0.03, 95% CI?=??0.36, 0.31). While the findings from this review suggest that mothers involved in integrated treatment programmes could potentially be less likely to experience out-of-home child placements and more likely to improve substance use treatment outcomes, little evidence exists for the effectiveness of these interventions. Further research, particularly high-quality RCTs, is required to demonstrate and persuade health and public policy on the far-reaching value of the integrated approaches.

Suicide risk is elevated in psychiatric patients following discharge from inpatient care. Despite this vulnerability, there has been limited research investigating suicide prevention protocols that take into account the unique system characteristics of this setting (e.g., short lengths of stay, crisis stabilization treatment model, multidisciplinary team coordination). Cognitive-behavioral therapy (CBT) has demonstrated efficacy for improving suicide risk in outpatients, but has not been validated with inpatients. The current study was a treatment development and pilot feasibility open trial that modified brief cognitive-behavioral therapy (BCBT) for an inpatient setting (BCBT-I). Key treatment modifications included administering up to 10 sessions (depending on patient length of stay), daily, and in a standardized order, with core crisis management skills introduced during the first three sessions. In addition, coordination with the inpatient treatment team was included in BCBT-I implementation. Six adult inpatients with a recent suicide attempt enrolled and completed an average of 4.67 BCBT-I sessions (SD = 1.36). The treatment was highly acceptable (Client Satisfaction Questionnaire total score M = 3.49, SD = 0.73). Pre- to posttreatment effect sizes demonstrated improvements in suicidal ideation (d = 0.97), depression (d = 1.33), and suicidal implicit associations (d = 1.28). All but one of the participants (83%) completed follow-up assessments 1-, 2-, and 3-months postdischarge. Over follow-up, two participants reported suicidal ideation (both without intent), and none reported suicide attempts, preparatory acts or behaviors, or nonsuicidal self-injury. This study provided preliminary evidence supporting the feasibility of CBT to treat suicidal inpatients. Future research is needed to validate BCBT-I in a larger, randomized controlled trial to determine whether BCBT-I reduces suicide risk beyond that afforded by inpatient treatment alone.  相似文献

Accurate analysis of data is vital to the validation of interventions. As such, there has been a recent increase in studies evaluating visual analysis training procedures. However, past investigations have not evaluated direct and indirect visual analysis training methods with matched instructional content that was systematically designed. Furthermore, training has rarely included assessment of generalization and maintenance of visual analysis skills. The purpose of the current dissertation study was to compare the effectiveness and efficiency of (a) computer‐based training, (b) lecture formats with and (c) without the opportunity to pause, and (d) a no‐training group to teach visual analysis of AB graphs to university students. To make these formats directly comparable, the instructional content was equated by ensuring information and examples were identical across the three training procedures. Eighty‐three students were randomly assigned to one of the four groups. Results showed that all three training formats produced increases in accurate responding compared to the no‐training group. Visual analysis skills generalized to novel graphs and maintained approximately 2 weeks following all trainings. These results suggest that structured approaches that are carefully designed to train visual analysis are effective and lead to gains that generalize and maintain in the absence of training.  相似文献
