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.

Major depressive disorder, dysthymia, and bipolar disorder are very common diagnoses seen among athletes, and they are serious conditions that can be debilitating if not properly addressed. These disorders warrant careful attention because they can adversely affect multiple domains of an athlete’s life, including athletic motivation, performance outcomes, interpersonal well-being, health, and overall daily functioning. Key foci include the prevalence of, clinical characteristics of, causes of, and risk factors for major depressive disorder, persistent depressive disorder/dysthymia, bipolar I disorder, and bipolar II disorder. Sport psychologists should integrate such important information into their overall case conceptualization and decision-making processes to ensure that athletes and performers at risk for, or struggling with, such mental health concerns receive the most effective, efficient, and timely care possible.

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 understandings 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 a conception of continuing bonds that can be adaptive in grief. Similarly, early stage theories of grieving 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 changed world. In sum, 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 accommodate 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 struggles 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), as well as being characterized by distinctive separation distress regarding the deceased. 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.

Attempts at informal personality assessment can be traced back to our distant ancestors. As the field of Clinical Psychology emerged and developed over time, efforts were made to create reliable and valid measures of personality and psychopathology that could be used in a variety of contexts. There are many assessment instruments available for clinicians to use, with most utilizing either a projective or self-report format. Individual assessment instruments have specific administration, scoring, and interpretive guidelines to aid clinicians in making accurate decisions based on a test taker’s answers. These measures are continuously adapted to reflect the current conceptualization of personality and psychopathology and the latest technology. Additionally, measures are adapted and validated to be used in a variety of settings, with a variety of populations. Personality assessment continues to be a dynamic process that can be utilized to accurately and informatively represent the test taker and aid in clinical decision making and planning.

Depression is a leading cause of global burden affecting people across all ages, genders, and socioeconomic groups. Antidepressants are the cornerstone of treatment, yet treatment response is often inadequate. While some psychological interventions such as cognitive behavioral therapy can also help alleviate depressive symptoms, alternative and complimentary treatment options are required. In particular, therapeutic interventions that also address the greatly increased levels of obesity and cardiovascular disease among people with depression may offer added value. With the rising burden of premature mortality due to cardiovascular disease in people with depression and promising evidence base for physical activity to improve depressive symptoms, it is important to review the role, benefits, and underlying neurobiological responses of exercise among people with depression.
There has been a growing body of evidence to suggest that higher levels of physical activity reduce a person’s risk of incident depression. It appears that lower levels of cardiorespiratory fitness increase an individual risk of depression, suggesting that physical activity and physical fitness have a key role in the prevention of depression. Moreover, exercise can improve depressive symptoms in those with subthreshold depressive symptoms and major depressive disorder. Despite the effectiveness of exercise, the optimal dose and frequency are yet to be fully elucidated. Nonetheless, exercise appears to be well accepted by people with depression, with relatively low levels of dropout from interventions, particularly when supervised by qualified professionals with expertise in exercise prescription. Various barriers to engaging in exercise exist and motivational strategies are essential to initiate and maintain exercise. A number of hypotheses have been postulated to determine the antidepressant effect of exercise; however, most are based on animal models or models elucidated from people without depression. Therefore, future representative research is required to elucidate the neurobiological antidepressant response from exercise in people with depression. Physical activity interventions targeting fitness should be a central part of the prevention and management of depression. In particular, physical activity interventions offer a viable option to prevent and address cardiometabolic abnormalities and cardiovascular disease, which account for a significant amount of premature deaths in this population and are not addressed by standard pharmacological and psychological therapies.

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.
