Research on the disparity in common mental health problems borne by sexual minority individuals has entered a stage of increasing theoretical complexity. Indeed, such a substantial disparity is likely not determined by a singular cause and therefore warrants diverse etiological perspectives tested with increasingly rigorous methodologies. The research landscape is made even more complex by the constant and rapid shift in the ways in which sexual minority people understand and characterize their own identities and experiences. This review introduces readers to this complexity by summarizing the historical legacy of research on the sexual orientation disparity in mental health, describing five contemporary theoretical explanations for this disparity and their supporting evidence, and suggesting theoretically informed interventions for reducing this disparity. Last, we offer an agenda for future research to accurately model the complexity of the pathways and solutions to the disproportionately poorer mental health of sexual minority populations.

As the numbers of older adults continue to increase globally, the need for facilitating healthy aging has become critical. While a physically healthy lifestyle, including exercise and diet, is important, recent research has highlighted a major impact of psychosocial determinants of health, such as resilience, wisdom, positive social connections, and mental well-being, on whole health. This article focuses on keeping the mind and brain healthy with psychosocially active aging. It has six sections: Philosophy Concepts of Wisdom, Resilience, and Well-Being; Wisdom: Clinical, Neurobiological, and Evolutionary Perspectives; Resilience, Adaptation, and Augmentation; Psychological Resilience, Brain Health, and Whole Person Health; Preventing Depression and Promoting Resilience and Well-Being in Old Age; and The Centenarian as a Model of Resilience and Well-Being. We discuss the biopsychosocial mechanisms and effectiveness of healthy lifestyle strategies and propose a framework for future research and its practical implications for promoting wisdom, resilience, and well-being at the individual, societal, and policy levels.

Throughout time, ethnoracial groups have endured a range of traumatic experiences as historically marginalized members of the United States. The consequences of these experiences have been referred to as historical trauma (HT): a collective trauma, inflicted on a group of people who share a specific identity, that has psychological, physical, and social impacts on succeeding generations. In this review, we examine the literature on HT in relation to US ethnoracial groups by defining HT, providing a background for its development, and describing critiques of the concept. We then review the literature on HT in relation to Indigenous Americans, African Americans, and Asian Americans. For each group, we address the nature of HT, the transmission of HT and its impacts, and healing strategies. We conclude with a summary of the benefits, limitations, and complexities of HT research as well as recommendations for future work in this area.

Receiving my doctorate in 1961 just as John F. Kennedy was inaugurated president of the United States, I was inspired by his sentiment that any person can make a difference, and every person should try. In this memoir I review my professional journey of trying to make a difference in researching, teaching, supervising, and practicing clinical psychology and psychotherapy. I began my career by working on an evidence base for projective techniques. Upon joining the Stony Brook faculty, I shifted my efforts to research on and practice of behavior therapy, and then to the incorporation of cognition in developing cognitive behavioral therapy. Further work on integration consisted of closing the gap between research and practice, lowering the barriers that existed across schools of therapy, and incorporating lesbian, gay, bisexual, and transgender issues into mainstream psychology.

To build a coherent knowledge base about what psychological intervention strategies work, develop interventions that have positive societal impact, and maintain and increase this impact over time, it is necessary to replace the classical treatment package research paradigm. The multiphase optimization strategy (MOST) is an alternative paradigm that integrates ideas from behavioral science, engineering, implementation science, economics, and decision science. MOST enables optimization of interventions to strategically balance effectiveness, affordability, scalability, and efficiency. In this review we provide an overview of MOST, discuss several experimental designs that can be used in intervention optimization, consider how the investigator can use experimental results to select components for inclusion in the optimized intervention, discuss the application of MOST in implementation science, and list future issues in this rapidly evolving field. We highlight the feasibility of adopting this new research paradigm as well as its potential to hasten the progress of psychological intervention science.

Racism and other forms of oppression threaten the well-being of racially and ethnically marginalized youth. Models of risk and resilience for marginalized youth have stressed the importance of addressing contextual and structural risk while emphasizing promotive factors such as cultural capital within their communities. Increasingly, research has focused on collective antiracist action as a form of coping with structural oppression. Importantly, supportive intergenerational relationships that develop within youths' everyday contexts may play a key role in catalyzing and reinforcing youths' engagement in antiracist action. This review advances a novel model for understanding how supportive nonparental adults from youths' everyday lives (i.e., natural mentors) influence youths' positive developmental outcomes and participation in antiracist action and how collective antiracist action, in turn, fosters liberation and racial justice. The creation of a more just and equitable society contributes to positive development among racially and ethnically marginalized youth.

In the United States, an estimated 4.2 million young people experience homelessness during critical stages in their development-adolescence and emerging adulthood. While research on youth homelessness often emphasizes risk and vulnerability, the field must situate these issues within the developmental trajectories of adolescence and emerging adulthood to effectively prevent and end youth homelessness. This review uses the Risk Amplification and Abatement Model (RAAM) as a conceptual framework for contextualizing the landscape of youth homelessness research in the United States since 2010. An extension of ecological models of risk-taking, RAAM emphasizes both risk and resilience, positing that negative as well as positive socialization processes across interactions with family, peers, social services, and formal institutions affect key housing, health, and behavioral outcomes for youth experiencing homelessness. This review applies RAAM to our understanding of the causes and consequences of youth homelessness, recent interventions, and recommendations for future directions.

Specific psychological treatments have demonstrated efficacy and represent the first-line approaches recommended for anorexia nervosa, bulimia nervosa, and binge-eating disorder. Unfortunately, many patients, particularly those with anorexia nervosa, do not derive sufficient benefit from existing treatments, and better or alternative treatments for eating disorders are needed. Less progress has been made in developing pharmacologic options for eating disorders. No medications approved for anorexia nervosa exist, and only one each exists for bulimia nervosa and for binge-eating disorder; available data indicate that most patients fail to benefit from available medications. Longer and combined treatments have generally not enhanced outcomes. This review presents emerging findings from more complex and clinically relevant adaptive treatment designs, as they offer some clinical guidance and may serve as models for future enhanced treatment research.

Effective tobacco policies are important for reducing the harm of tobacco use and can have a broad impact at the population level. This review provides an overview of how clinical science can inform tobacco policies with a focus on policies related to flavored tobacco products, using menthol cigarettes as an illustrative example. Specifically, this review summarizes the role of flavors in tobacco use and the history of regulation of flavored tobacco products by the US Food and Drug Administration (FDA), provides an overview of clinical research methods used to contribute to the scientific evidence to inform FDA tobacco policies, discusses key findings related to menthol tobacco products using these methods, and proposes future directions for clinical research. As the tobacco marketplace continues to evolve with new products and flavor chemicals, ongoing clinical science will be essential for establishing evidence-based policies to protect public health and reduce tobacco-related health disparities.

Substance use disorders (SUDs) have an enormous negative impact on individuals, families, and society as a whole. Most individuals with SUDs do not receive treatment because of the limited availability of treatment providers, costs, inflexible work schedules, required treatment-related time commitments, and other hurdles. A paradigm shift in the provision of SUD treatments is currently underway. Indeed, with rapid technological advances, novel mobile health (mHealth) interventions can now be downloaded and accessed by those that need them anytime and anywhere. Nevertheless, the development and evaluation process for mHealth interventions for SUDs is still in its infancy. This review provides a critical appraisal of the significant literature in the field of mHealth interventions for SUDs with a particular emphasis on interventions for understudied and underserved populations. We also discuss the mHealth intervention development process, intervention optimization, and important remaining questions.

Alcohol's link with sexuality is long-standing and prominent. While research continues to document robust associations between drinking and sexual behavior, scientific attention now centers primarily on evaluating mechanisms and attendant theoretical frameworks to advance our understanding of how alcohol exerts a causal impact. We describe four domains with reliable evidence of alcohol effects: sexualized social perceptions, sexual arousal, sexual risk taking, and sexual assault. We consider three contextual frames: distal factors associated with encountering opportunities for alcohol-involved sex, proximal factors associated with alcohol's acute effects, and distal-proximal interactions. We then examine the empirical support for mechanisms embedded within four theoretical frameworks: alcohol disinhibition, alcohol expectancy, alcohol myopia, and emotion regulation. Support for disinhibition mechanisms is evident with sexual arousal only. Expectancy and myopia mechanisms enjoy support across domains and make up bases for integrative expectancy-myopia causal explanations. Emotion regulation mechanisms evidence preliminary support in risk taking and sexual assault. Implications and future directions are considered.

Group-based trajectory modeling (GBTM) identifies groups of individuals following similar trajectories of one or more repeated measures. The categorical nature of GBTM is particularly well suited to clinical psychology and medicine, where patients are often classified into discrete diagnostic categories. This review highlights recent advances in GBTM and key capabilities that remain underappreciated in clinical research. These include accounting for nonrandom subject attrition, joint trajectory and multitrajectory modeling, the addition of the beta distribution to modeling options, associating trajectories with future outcomes, and estimating the probability of future outcomes. Also discussed is an approach to selecting the number of trajectory groups.

Evidence from epidemiological, clinical, and biological research resulted in the immune hypothesis: the hypothesis that immune system dysfunction is involved in the pathophysiology of schizophrenia spectrum disorders (SSD). The promising implication of this hypothesis is the potential to use existing immunomodulatory treatment for innovative interventions for SSD. Here, we provide a selective historical review of important discoveries that have shaped our understanding of immune dysfunction in SSD. We first explain the basic principles of immune dysfunction, after which we travel more than a century back in time. Starting our journey with neurosyphilis-associated psychosis in the nineteenth century, we continue by evaluating the role of infections and autoimmunity in SSD and findings from assessment of immune function using new techniques, such as cytokine levels, microglia density, neuroimaging, and gene expression. Drawing from these findings, we discuss anti-inflammatory interventions for SSD, and we conclude with a look into the future.

Depression is an eminently treatable disorder that responds to psychotherapy or medications; the efficacy of each has been established in hundreds of controlled trials. Nonetheless, the prevalence of depression has increased in recent years despite the existence of efficacious treatments-a phenomenon known as the treatment-prevalence paradox. We consider several possible explanations for this paradox, which range from a misunderstanding of the very nature of depression, inflated efficacy of the established treatments, and a lack of access to efficacious delivery of treatments. We find support for each of these possible explanations but especially the notion that large segments of the population lack access to efficacious treatments that are implemented as intended. We conclude by describing the potential of using lay therapists and digital technologies to overcome this lack of access and to reach historically underserved populations and simultaneously guarantee the quality of the interventions delivered.

In recent years there has been a surge of research conducted on the impostor phenomenon, with approximately half of all impostor phenomenon articles being published between 2020 and 2022 and growing interest in understanding how the impostor phenomenon affects racially and ethnically minoritized individuals. Questions around intersectionality remain about how to apply the impostor phenomenon to the experiences of minoritized individuals. In this review, we revisit the historical context of the impostor phenomenon. We address issues of nomenclature and current controversies regarding whether the impostor phenomenon () blames the victim, () should be included in the (DSM), and () is beneficial for individuals. In addition, we address the limitations of current research on racially and ethnically minoritized individuals, especially women of color. Finally, we conclude by discussing the need for a reconceptualized racialized impostor phenomenon as well as the need to establish new impostor phenomenon measures, conduct more quantitative research with diverse samples, and create culturally tailored interventions.

Research indicates that sexual orientation change efforts (SOCEs) are not effective and furthermore commonly lead to iatrogenic effects such as depression, anxiety, and even suicide. Negative attitudes toward homosexuality derive from most formal religions and are incarnated in medical and psychological theories that support and encourage SOCEs. Oppression of sexual minorities makes it unlikely that change requests by patients are voluntary. Recently there has been a dramatic change as the field moves from reparative to affirmative approaches. Here, we review the history of SOCEs, their consequences, current affirmative treatments, and future directions in the field as they pertain to the well-being of the queer community. From an institutional community psychology perspective, we argue that even if true conversion were possible, such efforts are unethical and should not be pursued even if requested. As is the case with all psychological/psychiatric interventions, the issue is not "can" but "ought."

Methods for handling missing data in clinical psychology studies are reviewed. Missing data are defined, and a taxonomy of main approaches to analysis is presented, including complete-case and available-case analysis, weighting, maximum likelihood, Bayes, single and multiple imputation, and augmented inverse probability weighting. Missingness mechanisms, which play a key role in the performance of alternative methods, are defined. Approaches to robust inference, and to inference when the mechanism is potentially missing not at random, are discussed.

The Alternative Model of Personality Disorders (AMPD) is a dimensional, empirically based diagnostic system developed to overcome the serious limitations of traditional categories. We review the mounting evidence on its convergent and discriminant validity, with an incursion into the less-studied ICD-11 system. In the literature, the AMPD's Pathological Trait Model (Criterion B) shows excellent convergence with normal personality traits, and it could be useful as an organizing framework for mental disorders. In contrast, Personality Functioning (Criterion A) cannot be distinguished from personality traits, lacks both discriminant and incremental validity, and has a shaky theoretical background. We offer some suggestions with a view to the future. These include removing Criterion A, using the real-life consequences of traits as indicators of severity, delving into the dynamic mechanisms underlying traits, and furthering the integration of currently disengaged psychological paradigms that can shape a sounder clinical science.

This in-depth review delves into the multifaceted realm of mass shootings and explores their epidemiology from a psychological perspective. The article presents a comprehensive examination of the prevalence, perpetrator and victim profiles, motives, and contributing factors associated with mass shootings. By investigating the intricate relationship between masculinity, domestic violence, military service, social media, fame-seeking, suicidal ideation, mental illness, and firearms, this article sheds light on the multifaceted nature of mass shootings. Moreover, it discusses the importance of implementing effective prevention strategies to address this growing public health concern. The findings from this review serve as a valuable resource for researchers, practitioners, policy makers, and the community at large, facilitating a deeper understanding of mass shootings and fostering the development of evidence-based solutions to prevent these tragic incidents.

Obsessive-compulsive disorder (OCD) in children and adolescents is a neurobehavioral condition that can lead to functional impairment in multiple domains and decreased quality of life. We review the clinical presentation, diagnostic considerations, and common comorbidities of pediatric OCD. An overview of the biological and psychological models of OCD is provided along with a discussion of developmental considerations in youth. We also describe evidence-based treatments for OCD in childhood and adolescence, including cognitive behavioral therapy (CBT) with exposure and response prevention (ERP) and pharmacotherapy. Finally, research evaluating the delivery of CBT in different formats and modalities is discussed, and we conclude with suggestions for future research directions.

Racial stress and racial trauma refer to psychological, physiological, and behavioral responses to race-based threats and discriminatory experiences. This article reviews the evidence base regarding techniques for coping with racial stress and trauma. These techniques include self-care, self-compassion, social support, mindfulness, cognitive restructuring, cognitive defusion, identity-affirming practices and development of racial/ethnic identity, expressive writing, social action and activism, and psychedelics. These strategies have shown the potential to mitigate psychological symptoms and foster a sense of empowerment among individuals affected by racial stress and trauma. While the ultimate goal should undoubtedly be to address the root cause of racism, it is imperative to acknowledge that until then, implementing these strategies can effectively provide much-needed support for individuals affected by racism.
