We challenge a prevalent belief that depression causes suicide and propose that certain symptoms of depression and other psychopathologies may function to prevent lethal self-injury. Theoretical and empirical evidence supports this position. As suicide posed an extreme fitness hazard throughout human evolution, our species evolved special-purpose psychological defences that continuously monitor and manage this danger. Last-ditch protections may present as diverse psychiatric phenomena. Mobilising in adolescence and adulthood in response to chronic distress, these usually stop suicidal thoughts from escalating into deadly actions. The theory is testable. We point to important implications for the clinical management of suicide and psychopathology.

Decision-making deficits, assessed cognitively, are often associated with mental health symptoms, however, this relationship is not fully understood. This paper explores the relationship between mental health disorders and decision-making, using the Cambridge Gambling Task (CGT). Our study investigated how decision-making varied across 20 different mental health conditions compared to controls in a sample of 572 young adults from the Minneapolis and Chicago metropolitan areas, using a computerized laboratory-based task. Almost all mental health conditions were associated with at least mild (i.e. at least small effect size) impairment in all three studied parameters of the CGT (risk adjustment, quality of decision-making and overall proportion of bet). Notably, binge eating disorder had the largest cognitive impairment and gambling disorder had moderate impairment. Post-traumatic stress disorder (PTSD) was associated with impaired decision-making while obsessive–compulsive disorder (OCD) and depression showed moderate impairment. Additionally, half of the disorders assessed had moderate to large impairment in risk adjustment.These findings suggest that mental health conditions may have a more complex cognitive profile than previously thought, and a better understanding of these impairments may aid in risk assessment and targeted clinical interventions. This study underscores the need for further research to determine the causal pathways between mental health conditions and cognition, as well as to better understand the day-to-day impact of such deficits.

Heavy substance use (SU) and substance use disorders (SUD) have complex etiologies and often severe consequences. Certain personality traits have been associated with an increased risk for SU(D), but far less is known about personality changes related to SU(D). This review aims to synthesize the existing literature on this research question. A systematic literature search was conducted from November 2022 to February 2023 in PubMed, EbscoHost, and Web of Science. Peer-reviewed original papers on SU(D)-related personality changes were included. Of 55 included studies, 38 were observational population-based studies and 17 were intervention studies. Overall, personality and SU measures, samples, study designs, and statistical approaches were highly heterogenous. In observational studies, higher SU was most consistently related to increases in impulsivity-related traits and (less so) neuroticism, while interventions in the context of SU(D) were mostly associated with increases in conscientiousness and self-efficacy and lasting decreases in neuroticism. Findings for traits related to extraversion, openness, conscientiousness, and agreeableness were mixed and depended on SU measure and age. Studies on bidirectional associations suggest that personality and SU(D) both influence each other over time. Due to their strong association with SU(D), impulsivity-related traits may be important target points for interventions. Future work may investigate the mechanisms underlying personality changes related to SU(D), distinguishing substance-specific effects from general SU(D)-related processes like withdrawal, craving, and loss of control. Furthermore, more research is needed to examine whether SU(D)-related personality changes vary by developmental stage and clinical features (e.g. initial use, onset, remission, and relapse).

Stress is a challenge among non-specialist health workers worldwide, particularly in low-resource settings. Understanding and targeting stress is critical for supporting non-specialists and their patients, as stress negatively affects patient care. Further, stigma toward mental health and substance use conditions also impacts patient care. However, there is little information on the intersection of these factors. This sub-analysis aims to explore how substance use and mental health stigma intersect with provider stress and resource constraints to influence the care of people with HIV/TB. We conducted semi-structured interviews (N=30) with patients (n=15) and providers (n=15, non-specialist health workers) within a low-resource community in Cape Town, South Africa. Data were analyzed using thematic analysis. Three key themes were identified: (1) resource constraints negatively affect patient care and contribute to non-specialist stress; (2) in the context of stress, non-specialists are hesitant to work with patients with mental health or substance use concerns, who they view as more demanding and (3) stress contributes to provider stigma, which negatively impacts patient care. Findings highlight the need for multilevel interventions targeting both provider stress and stigma toward people with mental health and substance use concerns, especially within the context of non-specialist-delivered mental health services in low-resource settings.

The paper aims to trace the distinctive character of the talk of the soul and to disentangle it from the talk of the mind. The key context will be the way in which we talk about souls that are ailing. As a point of departure, I use the later Wittgenstein’s notion of the soul as anti‐dualist and anti‐substantive, which brings it close to Dennett’s or Davidson’s philosophy of mind, but which Wittgensteinian ethicists have elaborated upon as concerned with matters of good and evil, and beauty. In relation to these concerns, the sense of the ailing soul is different from issues relating to mental health. I then discuss cases of ailments of the soul that would be misleading to analyse as matters of mental health (issues): addiction, racism, and environmental grief. I conclude with a plea for maintaining the talk of the soul as helpful for making sense of existential or beauty‐ or morality‐related ailments, yet as something that does not necessarily subscribe to any doctrine of the soul as a substance. In support, I also use arguments from the spheres of eco‐theology and public theology.

People buy some goods that they do not enjoy and wish did not exist. They might even be willing to pay a great deal for such goods, whether the currency involves time, commitment or money. One reason involves signaling to others; so long as the good exists, nonconsumption might give an unwanted signal to friends or colleagues. Another reason involves self-signaling; so long as the good exists, nonconsumption might give an unwanted signal to an agent about himself or herself. Yet another reason involves a combination of network effects and status competition; nonconsumption might deprive people of the benefits of participating in a network and thus cause them to lose relative position. With respect to real-world goods (including activities) of this kind, there is typically heterogeneity in relevant populations, with some people deriving positive utility from goods to which other people are indifferent, or which other people deplore. Efforts to measure people's willingness to pay for goods of this kind will suggest a welfare gain, and possibly a substantial one, even though the existence of such goods produces a welfare loss, and possibly a substantial one. Collective action, private or public, is necessary to eliminate goods that people consume but wish did not exist. Legal responses here might be contemplated when someone successfully maneuvers people into a situation in which they are incentivized to act against their interests, by consuming a product or engaging in an activity they do not enjoy, in order to avoid offering an unwanted signal. Prohibitions on waiving certain rights might be justified in this way; some restrictions on uses of social media, especially by young people, might be similarly justified.

Women are the fastest-growing population of people who use drugs in the US. As a group, they are more likely than men to experience stigma, poverty, and negative mental health outcomes. This article discusses the unique needs of women drug users in the US and provides suggestions on how to leverage national attention — and federal funding — to make harm reduction services in the US more gender sensitive, and, as a result, more effective in reducing harm for women who use drugs in this country.

Several jurisdictions across the globe have introduced legislation to legally permit the sale and consumption of recreational cannabis. This editorial considers current evidence from the rest of the world and asks how this might inform the possible consequences of ‘legalisation’ models in the UK.

In 2022, the Camden Coalition Medical-Legal Partnership began providing civil and criminal legal services to substance use disorder patients at Cooper University Health Care’s Center for Healing. This paper discusses early findings from the program’s first year on the efficacy of the provision of criminal-legal representation, which is uncommon among MLPs and critical for this patient population. The paper concludes with takeaways for other programs providing legal services in an addiction medicine setting.
