Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by developmentally inappropriate levels of hyperactivity, impulsivity, and/or inattention. ADHD is chronic, may persist into adulthood, and is associated with impairment in social and academic/work domains across the lifespan. Children and adolescents with ADHD often present with executive function deficits and emotion dysregulation, and these deficits may increase impairment and risk for co-occurring disorders. The etiology of ADHD is not yet understood, though research suggests that biological and environmental factors (e.g., family, community) contribute to its development and course. It should be noted that ADHD commonly co-occurs with additional psychiatric disorders, such as oppositional defiant disorder (ODD), conduct disorder (CD), and major depressive disorder.
Evidence-based assessment of ADHD requires information from multiple informants using multiple assessment methods to determine the presence of ADHD symptoms across settings and any co-occurring disorders. The evidence-based treatment options for ADHD are manifold. Pharmacotherapy for ADHD is common, although numerous behavioral interventions are also effective. Stimulant medications are commonly prescribed and are typically effective in ameliorating core ADHD symptoms. There is also evidence that the nonstimulant medication atomoxetine substantially decreases the symptoms of ADHD. Importantly, medication therapy works to reduce symptoms but typically does not alleviate the impairments associated with the disorder. Combined medication and behavioral interventions are more likely to reduce impairments and normalize behavior.
Competency to stand trial is a long-established legal principle in the U.S. criminal justice system that ensures that a criminal defendant’s right to a fair trial is protected. Fundamental justice requires that criminal defendants should be able to understand the charges against them, appreciate the nature and range of penalties, and communicate with their attorney. If they do not have the capacity in any of these areas, they may be found incompetent to proceed and the judicial proceedings are suspended until they are treated and competency is restored.
While competency to stand trial is the most commonly used term, competency in the criminal trial process encompasses all stages of participation in the legal process, including pretrial, trial, sentencing, and appeals. It is also a consideration if a defendant chooses to represent him or herself. Indeed, the term itself is misleading because few defendants actually go to trial, as the vast majority of cases are resolved through plea bargaining. The competency issue is raised when an officer of the court (defense, prosecution, or judge) has reason to believe there is a bona fide doubt as to a defendant’s competence. Once raised, defendants are typically referred for an evaluation by a mental health professional. Legal precedence has established that the basis of a finding of incompetency must be the presence of a major mental illness or substantial cognitive deficit. However, the mere presence of either of these conditions is not sufficient, as a functional approach to assessing competency dictates that the mental illness or cognitive deficit must be shown to affect the defendant’s specific legal competencies. It is entirely possible, for example, that some defendants with a psychosis or other severe mental illness may nevertheless be able to proceed with their case if the mental illness does not impair the legal abilities necessary to go forward.

Research in psychotherapy has developed a number of treatments, numbering well over 300, that have a strong evidence base. These treatments can be applied to a broad range of psychiatric disorders (e.g., depression, anxiety, schizophrenia, and others) as well as other sources of impairment in psychological functioning among children, adolescents, and adults. This article provides an overview of evidence-based psychotherapies, including current advances in how treatments are applied. Examples of treatments for depression and autism spectrum disorder are provided to illustrate the diversity of procedures in use and how they are applied. Key challenges related to evidence-based psychotherapies are highlighted, and these include disseminating the research findings, so that effective treatments are being used in clinical practice, and devising novel ways of delivering treatment to reach the large number of individuals who are in need of psychological services but do not yet receive care.

Death and loss are universal human experiences, yet understanding of and attitudes toward expressing grief have shifted across time. The earliest psychological conceptualization of grief pathologized “holding on” to the lost object, a notion that has since been rejected in favor of continuing bonds that are adaptive in grief. Similarly, early stage theory suggested a linear progression toward resolution and acceptance of loss, which has been criticized in favor of approaches that allow for natural regulatory processes of attending to the loss and reengaging with a world changed by loss. Grief is no longer regarded solely as looking back on a past life with the deceased, but rather is oriented toward creating and reconstructing a meaningful present and future that accommodates the loss and its impact.
Most people respond adaptively to loss by relying on their internal and social support systems. However, a significant subset of grievers struggle with complicated grief, which is characterized by intense longing for the deceased, causes impairment in various life domains, and extends beyond the period of grieving that is considered normal for the population and culture. Grief therapy is most appropriate and advantageous for grievers who self-identify the need for additional support, and this tends to happen among those who are struggling disproportionately. Complicated grief shares features with other common psychiatric diagnoses (e.g., major depressive disorder and posttraumatic stress disorder). Treatment for complicated grief targets the common symptoms among these disorders as well as the grief-specific manifestations of distress that are concentrated on issues of coping, attachment, meaning, and behavior.

Cognitive control is the ability to direct attention and cognitive resources toward achieving one’s goals. However, research indicates that anxiety biases multiple cognitive processes, including cognitive control. This occurs in part because anxiety leads to excessive processing of threatening stimuli at the expense of ongoing activities. This enhanced processing of threat interferes with several cognitive processes, which includes how individuals view and respond to their environment. Specifically, research indicates that anxious individuals devote their attention toward threat when considering both early, automatic processes and later, sustained attention. In addition, anxiety has negative effects on working memory, which involves the ability to hold and manipulate information in one’s consciousness. Anxiety has been found to decrease the resources necessary for effective working memory performance, as well as increase the likelihood of negative information entering working memory. Finally, anxiety is characterized by focusing excessive attention on mistakes, and there is also a reduction in the cognitive control resources necessary to correct behavior. Enhancing our knowledge of how anxiety affects cognitive control has broad implications for understanding the development of anxiety disorders, as well as emerging treatments for these conditions.

Obsessive-compulsive disorder (OCD) is one of the most destructive psychological disorders. Its symptoms often interfere with work or school, interpersonal relationships, and with activities of daily living (e.g., driving, using the bathroom). Moreover, the psychopathology of OCD is seemingly complex: sufferers battle ubiquitous unwanted thoughts, doubts, and images that, while senseless on the one hand, are perceived as signs of danger on the other hand. The thematic variation and elaborate relations between behavioral and cognitive signs and symptoms can be perplexing to even the most experienced of observers. Cognitive-behavioral models of OCD explain these phenomena and account for their heterogeneity. These models also have implications for how OCD is treated using exposure and response prevention, which research indicates are effective short- and long-term interventions.

Although psychotherapy is on balance effective for a broad array of psychological problems, a relatively small but steadily accumulating body of evidence suggests that at least some psychological interventions are harmful. Until recently, however, relatively little research attention has been paid to the identification of harmful psychological treatments. Although it has long been recognized that a nontrivial minority of people become worse following therapy, this finding does not necessarily mean that they have become worse because of therapy. Nevertheless, recent research has homed in on a small subset of interventions that may produce psychological harm, physical harm, or both. In addition, there is growing interest in pinpointing potential mechanisms of deterioration effects in psychotherapy, as well as in distinguishing harmful therapies from harmful therapists.

Psychodynamic psychotherapies (PDP) is an umbrella term for a variety of therapeutic modalities that have evolved out of the psychoanalytic/psychodynamic tradition, each theorizing a trajectory of human development that includes an etiology of and treatment for psychopathology. PDPs have in common the belief that people have an unconscious mind that influences thoughts and behaviors outside of the individual’s awareness. These processes operate from birth till death and are responsible for adaptive and maladaptive functioning at the level of interpersonal relationships and daily living.
The psychodynamic therapist creates a case formulation for the individual seeking treatment, which incorporates a formal diagnosis with an understanding of the underlying dynamic factors contributing to the individual’s suffering. From this case formulation a treatment plan is created specific to the individual. During treatment, the therapist develops a strong working alliance while utilizing psychodynamic-specific techniques targeted at bringing insight into these unconscious thoughts and behaviors. Greater self-understanding enables greater choice ability and flexibility in functioning.
In contrast to prevalent views, empirical research has found support for the efficacy of PDP in the treatment of mental disorders, including but not limited to: depression, anxiety disorders, somatic disorders, and personality disorders. In general, PDP was found more effective than control conditions and not different from active treatments. PDP effects have been shown to remain stable post treatment.

There are many approaches to psychotherapy, commonly called “schools” or “theories.” These schools range from psychoanalytic, to variations of insight- and conflict-based approaches, through behavioral and cognitive behavioral approaches, to humanistic/existential approaches, and finally to integrative and eclectic approaches. Different and seemingly new approaches typically have been informed by older and more established ones. For instance, cognitive behavioral therapy (CBT), one of the more widely used approaches, evolved from traditional behavior therapy but has become sufficiently distinct by adding its own complex variations so as functionally to represent an approach of its own.
New approaches abound both in number and in complexity. Modern clinicians have had to become increasingly widely read and creative in trying to understand the ways in which patients may be helped. The sheer number of approaches, which has climbed into the hundreds, has challenged the field to find ways of ensuring that the treatments presented are effective. The advent of Evidence Based Practices (EBP) throughout the healthcare fields has placed the responsibility on those who advocate for particular types of treatment scientifically to demonstrate their efficacy and effectiveness. While this movement has brought standards to the field and has offered some assurance that psychotherapy is usually helpful, there remains much debate about whether the many different schools produce different results from one another. The debate about how best to optimize positive effects of psychotherapy continues, and there remain many questions to be asked of psychotherapy theories and of research on these approaches.

Stigma is a complex process that results from the interaction of stereotypes, prejudice, and discrimination. When applied to health conditions (e.g., mental illness, HIV/AIDS, diabetes, obesity), stigma can contribute to a lack of recovery and resources as well as devaluation of the self. People with stigmatized health conditions may be too embarrassed to seek treatment and others may not provide them with equal opportunities. This often results in discrimination in employment, housing, and health care settings. Strategies have been proposed to prompt stigma change with strategic contact between those with the health condition and everyone else likely to have the best effects.
