Temple University This commentary on the special section on clinical adolescent psychology (G. Holmbeck & P. Kendall, 2002) reviews and critiques the conceptual and empirical articles that this compilation comprises. As articulated in the conceptual contributions to this collection, two fundamental principles should guide research on the etiology, prevention, and treatment of psychological disorder and dysfunction during adolescence: First, drawing on the field of developmental psychopathology, the study of clinical adolescent psychology should focus on the trajectories of disorder that precede, characterize, and follow adolescence. Second, drawing on the literature on normative adolescent development, the study of clinical adolescent psychology must proceed with an explicit recognition of the unique biological, cognitive, psychosocial, and contextual features that define adolescence as a developmental period. The empirical contributions to this compilation are evaluated with respect to the extent to which they reflect these tenets. Although the study of clinical adolescent psychology, as evidenced by this collection of articles, is appropriately grounded in the broader enterprise of developmental psychopathology, less progress has been made with respect to the integration of the study of clinical phenomena in adolescence with the study of normative adolescent development. clinical phenomena in the context of adolescence as a developmental period, rather than the study of clinical phenomena among individuals who merely happen to be older than children and younger than adults. The latter is what the field has been doing. The former is what the field should be doing. The distinction between the two is both subtle and profound, and it has important implications for the ways in which we conceive, study, diagnose, and treat emotional and behavioral problems among young people. The current set of articles helps to focus attention on both what is, and what is not, the sort of research that is appropriately classified as clinical adolescent psychology as I have defined it in the preceding paragraph. The first four articles in the collection provide the theoretical and conceptual underpinnings of this emerging field, whereas the five empirical reports that follow provide examples of what research that adheres to at least some of these principles might look like. I say “some,” and not “all,” of these principles because, as I shall make clear, the five studies are truer to some of these principles than they are to others. Thus, although the empirical reports nicely illustrate the best of what the current study of clinical adolescent psychology has to offer, their limitations also reveal how much further our research needs to go to fulfill the expectations set forth in the four foundational articles by Holmbeck and Kendall (2002), Cicchetti and Rogosh (2002), Weisz and Hawley (2002), and Cauce et al. (2002). Let me begin by elucidating what I think are the main points raised by the first four articles. Holmbeck and Kendall (2002), in their introduction to the issue, “focused on the interface between the fields of developmental and clinical psychology” (p. 3) and use this as a jumping-off point to raise seven specific questions that are at the heart of the study of clinical adolescent psychology: (1) Why does age of onset vary across disorders?, (2) Do the precursors of child-onset versus adolescent-onset disorders differ?, (3) Does symptom presentation change between childhood and adolescence (and I would add, between adolescence and adulthood)?, (4) How is adaptation affected by mastery of the developmental tasks of For centuries, the study of psychological maladjustment and the study of adolescent development have been inextricably linked, both conceptually and empirically. Philosophers, clinicians, scientists, and virtually all observers of human behavior have long noted that adolescence is a period of special significance for the emergence or intensification of various forms of emotional and behavioral disorder, including many internalizing problems (e.g., depression, eating disorders), externalizing problems (e.g., delinquency, violence), and addictive disorders (e.g., alcohol abuse and dependency, drug abuse and dependency). Although scholars may disagree about why adolescence is so important to the study of clinical phenomena, there is little dispute over whether it is important. Indeed, the list of clinical phenomena that are not primarily associated with adolescence (e.g., bipolar illness, autism, dementia) is probably shorter than the list of clinical phenomena that are. To the extent that the designation “clinical adolescent psychology” merely describes the study of psychological disorder among individuals between the ages of 10 years and 20 years, it is little more than a label for a field that has existed for some time but that was unaware of its own existence. My suspicion is that the editors of this special issue had something else in mind when they decided to invite the series of articles contained herewith, however. Rather than use the label “clinical adolescent psychology” to describe an already extant enterprise, they have coined the term to draw attention to a way of thinking about clinical phenomena that reflects a paradigmatic shift—a shift away from seeing psychological disturbance during adolescence as either the grown-up version of childhood disorder or the immature or prodromal counterpart of adult pathology. As reflected in this compilation of articles, “clinical adolescent psychology” refers to the study of Correspondence concerning this article should be addressed to Laurence Steinberg, Department of Psychology, Temple University, Philadelphia, Pennsylvania 19122.

SPECIAL SECTION: CLINICAL ADOLESCENT PSYCHOLOGY adolescence?, (5) What developmental pathways in childhood affect the likelihood of psychopathology in adolescence?, (6) What developmental and contextual processes mediate or moderate the links between socialization and adolescent adjustment?, and (7) Does treatment effectiveness vary as a function of the client’s developmental level? This introductory essay leads nicely into the overview of the field of developmental psychopathology provided by Cicchetti and Rogosh (2002), who note that “a developmental [psychopathology] approach requires that an issue of interest be conceptualized in terms of how it would be manifested in view of the particular developmental capacities and attainments of the adolescent period of development” (p. 7). Their argument is that clinical phenomena during adolescence must be understood against a backdrop of normative adolescent development and studied with specific reference to the developmental challenges of the period. Doing so requires that investigators and practitioners focus on the developmental trajectories of disorder to understand how the nature, antecedents, correlates, and consequences of various types of dysfunction are transformed as individuals move into, through, and out of the adolescent period. Cicchetti and Rogosh’s overview reminds us that it is important to stress the “developmental” in developmental psychopathology, for it helps push us to see adolescence as a period of development, and not simply as an age range. This theme—attempting to understand what it is about adolescence as a developmental period that affects the expression, course, and treatment of psychological disorder—is front and center in the article by Weisz and Hawley (2002). Their systematic and trenchant examination of the treatment-outcome literature asks whether and to what extent treatments for various psychological disorders among adolescents actually take into account the fundamental features of adolescent development. Thus, they ask whether cognitive-based treatments factor in the development of abstract reasoning, a hallmark of adolescent intellectual development, or whether our understanding of puberty and its impact on psychological functioning finds its way into therapeutic approaches for the treatment of internalizing or externalizing problems. Their conclusion is worrisome, for it reveals just how little of the kind of integration of developmental and clinical psychology called for by Holmbeck and Kendall (2002) has found its way into the treatment community or, for that matter, into the community of researchers who study treatment effectiveness. For the most part, the therapies directed at adolescents with psychological problems look no different than those directed at children or at adults who suffer from the same maladies. One issue not discussed by Weisz and Hawley (2002), but which strikes me as a crucial consideration, is the extent to which the absence of developmentally sensitive treatments for adolescents is as much a reflection of the absence of a developmentallyappropriate taxonomy of disorder as it is a reflection of a lack of developmental thinking within the treatment community. Perhaps part of the reason practitioners and developers of clinical interventions for adolescents do not think developmentally is that the categorization and definition of disorder they are responding to is itself so adevelopmental. After all, the criticism that Weisz and Hawley quite rightly aimed at the developers of interventions applies in spades to those who have developed the Diagnostic and Statistical Manual of Mendal Disorders (e.g., 4th ed., American 125 Psychiatric Association, 1994) and other diagnostic systems, which, as Jensen and others have pointed out (Jensen & Hoagwood, 1997), force practitioners to apply a taxonomy of disorder developed from clinical observation of adults to children and youth. One wonders whether the sort of changes that Weisz and Hawley call for in the way we think about treatments are likely to occur without a concomitant transformation in the way we think about disorder. The Cauce et al. (2002) contribution broadens the discussion of clinical adolescent psychology as an enterprise. In addition to developmentally sensitive research on the diagnosis and treatment of mental disorder during adolescence, these authors call for systematic services research, a woefully understudied area among psychological researchers, particularly among those who study children and youth. It goes without saying that the sorts of improvements in the design of treatment protocols for adolescents with psychological problems called for by Weisz and Hawley (2002) will do little to improve the mental health of adolescents if young people who need treatment do not receive it. Yet, as Cauce et al. (2002) point out, the field of services research has not looked systematically at adolescents as consumers of psychological services, and they persuasively argue that the study of clinical adolescent psychology should include studies of which adolescents actually receive mental health services, of the processes through which adolescents actually obtain mental health services, of the impediments to mental health service delivery to adolescents, and of the range of services, including services from nontraditional providers, that adolescents actually receive. As a developmental period, adolescence is a fascinating one within which to study service utilization, because adolescents are autonomous enough to seek out mental health services on their own but often dependent on adults to actually gain access to the services they seek. Implicit in Cauce et al.’s (2002) argument is the notion that mental health services research, like research on etiology and treatment, must be designed with adolescence as a developmental period in mind; it will be of little value to simply replicate extant services research on adults with samples of younger individuals without taking into account developmental differences between adolescents and adults and attempting to understand how these differences affect help-seeking behavior. But research on help seeking among adolescents must attend to the importance of ethnicity as well as to the importance of development. Given that a sizable proportion of the adolescent population in the United States is from ethnic minority backgrounds, and in light of the fact that ethnic minority youth are disproportionately likely to need mental health services but disproportionately unlikely to receive them, any research on services provision and utilization must seek to understand the causes of, and remedies for, problems of differential access. Two overarching principles emerge from these four stagesetting articles that, in my view, are fundamental to the study of clinical adolescent psychology. First, the study of clinical adolescent psychology requires some understanding of the trajectories of disorder that precede, characterize, and follow adolescence. Second, the study of clinical adolescent psychology must proceed with an explicit recognition of the unique biological, cognitive, psychosocial, and contextual features that define adolescence as a developmental period. The first principle is central to the study of developmental psychopathology; the second is central to the study This document is copyrighted by the American Psychological Association or one of its allied publishers.

Implicit in Holmbeck and Kendall’s (2002) seven questions is a call for research that incorporates both points of view. The five empirical reports that complete this compilation represent research from some of the top groups in the country currently studying clinical adolescent psychology, and in this sense, they provide the perfect opportunity to ask how well the best of what is being done in this area meets the implicit standards set out in the first four articles of this issue. I think it is fair to say that the reports deliver more on the developmental psychopathology front than they do on the adolescent development front. Indeed, the contrast between the clear and incontrovertible influence on contemporary adolescent clinical psychology of the developmental psychopathology perspective, as articulated by Cicchetti and Rogosh (2002), and the surprising absence of attention to the fundamentals of normative adolescent development is readily apparent in the present set of empirical articles. Thus, the good news is that researchers studying clinical phenomena in adolescence are taking seriously the need to understand developmental trajectories of both individuals (e.g., Chassin, Pitts, & Prost, 2002) and groups (Garber, Keiley, & Martin, 2002), to examine the interplay of risk and protective factors (Stouthamer-Loeber, Loeber, Wei, Farrington, & Wikström, 2002), to examine typical development in atypical populations (Holmbeck et al., 2002), and to place psychopathology in a relational context (Allen et al., 2002). In these respects, the studies contained in this issue make it quite apparent that contemporary research on clinical adolescent psychology, at least as it is conducted by the very best people in the field, is adhering to many of the fundamental principles that are foundational to the field of developmental psychopathology. It is beyond the scope of this brief commentary to discuss in any detail the specific findings of the five articles, and the articles are so well written that readers will not need any assistance in making sense of what they say. What is most impressive about them, as a group, is that they illustrate how the application of the developmental psychopathology perspective broadens our understanding of clinical phenomena in adolescence in ways that would not be possible within a conventional clinical psychology perspective. In this sense, the articles are more important in their illustrative capacity than in their specific findings. For example, we see in Chassin et al.’s (2002) report on binge drinking an exemplary demonstration of how one combines techniques to model developmental trajectories with a cluster analytic approach, in order to characterize a population in terms of groups of individuals following different developmental pathways—a blending of nomothetic and idiographic approaches that would apply equally well to the longitudinal data presented by Garber et al. (2002), on developmental trajectories of depressive symptomatology. Chassin et al.’s analyses reveal that examining differences among individuals in their trajectories of binge drinking may be more informative, and more predictive of subsequent illness, than focusing on differences among individuals at any one point in time. During the early years of high school (e.g., ages 14 –15 years), for example, the frequency of problem drinking observed among adolescents who would later become heavy binge drinkers was no different from that observed among those whose binge drinking would remain infrequent. Only by studying trajectories of binge drinking over time were these researchers able to identify those adolescents who were at greatest risk for developing alcoholism in adulthood. Where Chassin et al.’s (2002) approach could benefit from the tack taken by Garber et al. (2002) is in the latter’s innovative strategy of modeling developmental trajectories of symptoms in relation to developmental trajectories of the factors presumed to drive the clinical phenomenon under investigation, in this case, the impact of changes in depressogenic cognitions on changes in depressive symptomatology. Whereas Chassin and her colleagues use static variables measured at single points in time to predict trajectories of binge drinking, Garber and her collaborators examine changes in their outcome of interest as a function of changes in one or more predictors. Accordingly, not only are Garber et al. able to say something about static predictors of patterns of change in depression over time (to be sure, a contribution in and of itself), they are also able to show that changes in cognitions precede changes in symptoms. This is terribly important, not only for understanding the etiology of depression, but for the design of treatment programs and preventive interventions. Both Chassin et al. (2002) and Garber et al. (2002) have adopted a risk factor approach to the study of the development of psychopathology, attempting to isolate those particular risk factors that have the most predictive power. Stouthamer-Loeber et al. (2002) extended this approach by looking simultaneously at risk and protective (or in their terminology, “promotive”) factors related to engagement in antisocial behavior, a strategy that derives from studies of risk and resilience. Their approach is grounded in the belief that it is just as important to understand the factors that protect against delinquency as it is to understand the factors that increase the risk of antisocial behavior. As they point out, the distinction is not merely conceptual—it is practical as well. Risk factor research is important in identifying those factors that make adolescents vulnerable to various types of psychopathology, but as Stouthamer-Loeber et al. point out, in many instances there is little that psychologists can do about the prevention or diminution of the most powerful components of risk, such as neighborhood poverty or household composition. For this reason, it may be more useful to understand the factors that promote mental health among adolescents exposed to risk than it is to understand risk itself, because these promotive factors may well be things that psychologists can realistically hope to affect. Unfortunately, few investigators have adopted this approach, and most researchers who study psychological disturbance in adolescence continue to study risk without studying protection. As Stouthamer-Lober et al. (2002) noted, their analysis does not differentiate among types of risk or types of protection—instead, these researchers proceed from the assumption that more risk is bad and more protection is good. Although other researchers may take issue with this conceptualization, my reading of the literature on the role of context in the development of psychopathology supports the logic of these authors’ approach. The search for the specific risk and protective factors that predict particular forms of adolescent psychopathology has proven futile (Steinberg & Avenevoli, 2000). Instead, it appears that stress is a nonspecific trigger of psychological disorder, with the form of the disorder determined largely by factors internal to the adolescent, such as temperament or, as Garber et al. (2002) demonstrate, a particular cognitive style. Although the Chassin et al. (2002), Garber et al. (2002), and Stouthamer-Loeber et al. (2002) articles make important contributions to the study of clinical adolescent psychology by injecting a developmental psychopathology perspective into the picture, the This document is copyrighted by the American Psychological Association or one of its allied publishers.

SPECIAL SECTION: CLINICAL ADOLESCENT PSYCHOLOGY articles fall short when it comes to incorporating an adolescent development framework into their study of clinical phenomena. Indeed, although the three studies are studies of adolescents, the research is not really about adolescence in the sense that Cicchetti and Rogosh (2002) or Weisz and Hawley (2002) suggest it should be. Apart from the fact that binge drinking, depression, and delinquency are not generally phenomena that one sees much before adolescence, the participants in the three studies could have been virtually any age, and the research designs used and the constructs measured would have been for the most part perfectly appropriate. One potential remedy for this is the addition of measures of developmental status to the design of longitudinal studies of clinical phenomena to supplement chronological age as the metric against which changes in the dependent variables of interest are tracked. For example, studies of drinking, depression, or delinquency in adolescence might track changes in these phenomena as a function of pubertal maturation, the development of hypothetical thinking, growth in autonomy or identity, changes in family or peer relationships, or school transitions. The incorporation of these markers of adolescent development— biological, cognitive, emotional, and social—would help elucidate the underlying processes by which clinical phenomena change as individuals mature into and through adolescence, not just over time. One may fairly ask whether the same sort of criticism that Weisz and Hawley (2002) leveled at those who have designed and studied treatments for adolescent mental health problems—that the treatments or their evaluation rarely pay attention to the unique biological, psychological, and social aspects of adolescent development— could be directed at these otherwise exemplary studies. The hallmarks of adolescent development—pubertal maturation; the emergence of abstract thinking; shifts in social status; and the psychosocial challenges of identity, autonomy, intimacy, and sexuality, for example—play virtually no role in these research designs. Thus, although each of these research programs attempts to track change in a clinical phenomenon as a function of time (i.e., alcohol abuse, depression, and delinquency), none attempts to track change in these phenomena as a function of development. The articles by Holmbeck et al. (2002) and by Allen et al. (2002) are interesting to consider in tandem, both because they do focus on adolescent development and because each concerns the links between family functioning and adolescent adjustment. The Holmbeck et al. article makes an important contribution to the study of parental control and its impact on psychological functioning, in particular, a topic that has seen revived interest in recent years (e.g., Barber, 2001). Holmbeck and his colleagues draw a distinction between psychological control, which is often hostile, and overprotectiveness, which is not. Most researchers have treated these phenomena as interchangeable variants of enmeshment or intrusiveness, but as Holmbeck et al. pointed out, the psychological experience of being on the receiving end of overprotectiveness (e.g., feeling babied) may be very different from that of psychological control (e.g., feeling manipulated). Even though overprotectiveness may derive from parental concern, however, as it most likely does among parents whose adolescent suffers from a chronic illness, there is still the possibility of too much of a good thing. As Holmbeck and his colleagues discover, closeness can become problematic when it crosses the line from concern to overprotection because it may interfere with the adolescent’s developing 127 sense of autonomy, and threats to autonomy may result in emotional and behavioral problems. The link between adjustment and autonomy is also a focus in the Allen et al. (2002) article. Like Holmbeck and his colleagues, Allen and his collaborators examined adolescent maladjustment within the context of a family system engaged in the renegotiation of the emotional contours of the parent–adolescent relationship. Not surprisingly, adolescents who report greater security in their attachment to parents show healthier patterns of social development, reaffirming the well-established finding that an emotionally healthy parent–adolescent relationship, as reflected in the adolescent’s security of attachment, is predictive of positive psychological functioning. The importance of having a healthy attachment to parents is indirect as well as direct, however, in that the quality of attachment appears to moderate the links between autonomy and adolescent functioning. Among adolescents with secure attachments to parents, displays of autonomy during family interaction were associated with positive development. Among adolescents whose attachments were less healthy, autonomy in the family context had negative effects. The Allen et al. article serves as a reminder that studies of the development of autonomy in the family and its relation to psychopathology must take into account the level of closeness between adolescents and parents at the same time. Autonomy in the context of a problematic parent–adolescent relationship has different effects than autonomy in the context of a healthy attachment (Lamborn & Steinberg, 1993). The Holmbeck et al. (2002) and Allen et al. (2002) articles provide further evidence that the optimal family environment for adolescent development is one that balances independence and interdependence, a finding that has now been reported frequently in the literature on adolescent development. As I have written elsewhere, “we know some things” about familial influences on adolescent development (Steinberg, 2001), and one of them is that adolescents need to establish a sense of autonomy from parents within a relational context that is warm and connected. Disruptions in the balance between autonomy and connectedness may result from, accompany, and lead to psychological and emotional difficulties. With their emphasis on attachment and autonomy, the articles by Allen et al. (2002) and Holmbeck et al. (2002) locate themselves more centrally within the broader literature on normative adolescent development than do the other empirical reports in this special issue. But whereas both of these studies examined psychosocial phenomena that are central to the study of adolescent development, neither focused on the sort of serious pathology studied by Chassin et al. (2002), Garber et al. (2002), and Stouthamer-Loeber et al. (2002). The Allen and Holmbeck articles are important contributions to our understanding of the ways in which the family contributes to the development of psychological adaptation and maladaptation in adolescence, but I think it is fair to say that these studies are more about adjustment difficulties than they are about serious psychopathology. At least with respect to the current set of research reports, then, it appears that the more the research is about psychopathology, the less it is it about development, and the more it is about development, the less it is about psychopathology. And this is precisely the problem that needs fixing. The challenge, it seems to me, is to find ways of taking the sorts of developmental concerns that are central to the Holmbeck et al. STEINBERG This document is copyrighted by the American Psychological Association or one of its allied publishers.

(2002) research programs— concerns like the study of autonomy and attachment in the adolescent’s family context—and injecting them into the research of investigators like Chassin et al. (2002), Garber et al. (2002), Stouthamer-Loeber et al. (2002), and others who are studying the sort of serious psychopathology of interest to clinicians who work with adolescent populations. If the field of adolescent clinical psychology is to fulfill its promise, we need to move from research that is simply at the “interface between the fields of clinical and developmental psychology” (Holmbeck & Kendall, 2002, p. 3) to research that reflects the genuine integration of these disciplines. Fostering the interface of these disciplines, as this special section does, is the necessary first step, but it is only a beginning. Not until we see the seamless integration of clinical and developmental psychology in research on adolescent psychopathology will we begin to bear the intellectual fruit of the sort of interdisciplinary collaboration to which the emerging field of clinical adolescent psychology aspires.
