Introduction
Stefan G. Hofmann and Patricia M. DiBartolo
Based on the success of our earlier two volumes, we were encouraged to pursue
another edition to update the field with the dramatic changes that have occurred
in the field of social anxiety. This third edition of our volume includes again
many of the foremost experts in the field of social anxiety from a variety of dif-
ferent disciplines, including social psychology, clinical psychology, psychiatry,
developmental psychology, neuroscience, and behavior genetics. The volume is
separated into three parts: Part 1: Delineation of Social Anxiety; Part 2: Theo-
retical Perspectives; and Part 3: Treatment Approaches.
The first part (Part 1: Delineation of Social Anxiety) examines the clini-
cal definition of social anxiety disorder (Chapter 1 by Daniel W. McNeil and
Cameron L. Randall), its overlap with avoidant personality disorder (Chapter 2
by James Reich), methods to assess social anxiety and its clinical expressions
(Chapter 3 by James D. Herbert, Lynn L. Brandsma, and Laura Fischer) and the
overlap between social anxiety and shyness (Chapter 4 by Lynne Henderson,
Paul Gilbert, and Philip Zimbardo) and embarrassment (Chapter 5 by Rowland
Miller). Moreover, this section examines the different expressions of social anx-
iety across different cultures (Chapter 6 by Keila C. Brockveld, Sarah J. Perini,
and Ronald M. Rapee), the overlap between social anxiety and perfectionism
(Chapter 7 by Gordon L. Flett and Paul L. Hewitt), social skills (Chapter 8 by
Ariel Stravynski, Angela Kyparissis, and Danielle Amado), and the expression
of social anxiety disorder in adults (Chapter 9 by Amy Wenzel and Shari Jager-
Hyman), and children and adolescents (Chapter 10 by Michael F. Detweiler,
Jonathan S. Comer, Kathleen I. Crum, and Anne Marie Albano). We also in-
cluded a chapter on prevention and early intervention (Chapter 11 by Paula
Barrett and Marita Cooper).
The second part (Part 2: Theoretical Perspectives) includes a chapter re-
viewing the neuroendocrinological and neuroimaging studies in social anxiety
disorder (Chapter 12 by K. Luan Phan and Heide Klumpp) as well as basic
issues in temperament (Chapter 13 by Jerome Kagan) and the relationship be-
tween social anxiety and one particularly relevant temperament—behavioral
inhibition (Chapter 14, also by Jerome Kagan). Chapter 15 by Daniel W.
McNeil, Cameron L. Randall, C. W. Lejuez, and John T. Sorrell presents learn-
ing and behavior change mechanisms related to social anxiety disorder while
Chapter 16 (by Jennie M. Kuckertz and Nader Amir) reviews the cognitive bias
literature, followed by emotion dysregulation models (Chapter 17 by Philippe

xxvi Introduction
R. Goldin, Hooria Jazaieri, and James J. Gross), self-related processes
(Chapter 18 by Lynn E. Alden, Karen W. Auyeung, and Leili Plasencia),
and deficits in positive emotions (Chapter 19 by Antonina S. Farmer, Todd
B. Kashdan, and Justin W. Weeks). Also included is a revision of Mark R.
Leary’s early warning system (Chapter 20, written with Katrina P. Jongman-
Sereno) and a chapter on evolutionary perspectives (Chapter 21 by Eva Gilboa-
Schechtman, Iris Shachar, and Liat Helpman).
In the final part (Part 3: Treatment Approaches), authors review the ther-
apy literature, including pharmacological treatments (Chapter 22 by Carlos
Blanco, Laura Bragdon, Franklin R. Schneier, and Michael R. Liebowitz)
and various psychological interventions (Chapter 23 by Kristin N. Anderson and
Debra A. Hope). Chapter 24 by Richard G. Heimberg, Faith A. Brozovich and
Ronald M. Rapee provides an update of the influential cognitive model. Bram
Van Bockstaele and Susan M. Bögels (Chapter 25) review mindfulness-based
therapy for social anxiety disorder. Mark B. Powers, Brooke Y. Kauffman,
Allison Diamond, and Jasper A. J. Smits review the literature comparing pharma-
cotherapy and psychological treatments (Chapter 26) and the volume concludes
with a review by Michael W. Otto, Steven A. Safren, and Bridget A. Hearon of
the mechanisms of action in treatment (Chapter 27).
As is evident, social anxiety has captured the interest of some of the bright-
est contemporary thinkers of our time and from a multitude of different dis-
ciplines. This explosion of research interest and theoretical developments has
provided much needed understanding into the universal and transient feelings
of social anxiety as well as the less common, but unremitting and debilitating,
condition of social anxiety disorder.
It is our hope that our volume consolidates some of the latest evidence and
conceptual theories on this topic. We also hope that the breadth of perspective
represented in this volume will provide a step further toward understanding so-
cial anxiety and its clinical expression. This continues to be an exciting time as
our field continues to make significant advances in our understanding, concep-
tualization, and treatment of a defining aspect of humans that can turn into a
debilitating problem.

Conceptualizing and Describing
Social Anxiety and Its Disorders

INTRODUCTION
Social anxieties and fears exist along continua of intensity, ranging from the
helpful and adaptive (e.g., keeping one on one’s “social toes” in uncertain so-
cial situations) to the disabling and impairing (e.g., being unable to develop
or maintain close relationships in spite of loneliness). Unpleasant emotional
states and maladaptive behaviors associated with social situations can be sig-
nificant, life-affecting problems for many people. Given the social nature of
human beings, and the functional nature of social relationships (e.g., social sup-
port), discomfort associated with interacting with others is particularly difficult,
as socialization cannot easily be avoided on a consistent basis. In other phobias
or phobic-like disorders, avoidance often can be effective in the short term, to
prevent or reduce anxiety, albeit temporarily in many situations.
Social anxieties and fears were described by Hippocrates and were systemati-
cally delineated with other phobias beginning in the 1870s (Marks, 1970, 1985).
Over the past 40 years, the social psychological focus on shyness (e.g.,
Zimbardo, 1977), the work of Marks and others in the 1960s and 1970s, and the
identification of social phobia as a distinct disorder in the Diagnostic and Sta-
tistical Manual–III (e.g., American Psychiatric Association [APA], 1980) and
subsequent revisions, including the new Diagnostic and Statistical Manual of
Mental Disorders-5 (DSM-5; APA, 2013), have been part of a massive growth
in the related scientific and self-help literatures.
This general arena of problems includes several somewhat overlapping con-
structs; the scientific language has many different terms that apply or relate, in-
cluding: shyness, social anxiety, social withdrawal, social phobia, social anxiety
disorder, behavioral inhibition, communication apprehension, and introversion.
In both everyday and scientific language, these states have been described in a
myriad of ways. Leitenberg (1990), in introducing his book in the area, states:
Social anxiety has been studied in various guises. Shyness, performance anxiety,
social phobia, avoidant personality disorder, social withdrawal, social isolation,

public speaking anxiety, speech anxiety, communication apprehension, fear of
interpersonal rejection, dating anxiety, separation anxiety, stage fright, fear
of strangers, shame, embarrassment, social inhibition, social timidity – all of
these and more fall under the umbrella of social anxiety. (p. 2)
Other anxiety-related syndromes, such as test anxiety and selective mutism,
also likely have a strong social component, and may be instantiations of social
anxiety disorder (SAD) (Bögels et al., 2010). Body dysmorphic disorder, highly
comorbid with SAD, similarly is socially determined, at least in part, in that the
perception of others regarding (imagined) defects may be an underlying feature.
There also are a variety of terms that suggest, at least somewhat, deficient
social skills, such as nerd, geek, and wall flower. Masia and Morris (1998) iden-
tify terms related to social distress in children across areas of psychology: de-
velopmental (i.e., peer neglect, social withdrawal), personality (i.e., shyness),
and clinical (i.e., social phobia, avoidant personality disorder [APD]). Stranger
anxiety and separation anxiety likely are related constructs as well (Thompson
& Limber, 1990). Masia and Morris note that this varying “psychological lan-
guage” (p. 212) creates problems in investigating phenomena (e.g., parental be-
havior and its relation to child social anxiety) that span across subdisciplines in
psychology, and presumably across related disciplines (e.g., psychiatry).
It should be noted that comparative psychology has contributions to this
area as well. Social anxieties are not solely human phenomena; such social/
emotional problems are shared by other primates (Mineka & Zinbarg, 1995;
Suomi, Chaffin, & Higley, 2011), and lower animals. Social dominance and
submissiveness hierarchies have been suggested as important determinants
of socially anxious behavior across species of primates, including humans
(Schneier & Welkowitz, 1996; Trower & Gilbert, 1989). Facial expressions, for
example, provide important social interactional cues in humans and other pri-
mates, including both aggression and appeasement related to anxiety (Mogg &
Bradley, 2002; Öhman, 1986). Early learning history, particularly mother-
offspring interaction, also has been suggested as an important determinant of
socially anxious behavior in primates (e.g., Schino, Speranza & Troisi, 2001).
One of the issues that continues to be an albatross for the field is the every-
day language basis of the most frequently used terms: shyness, stage fright, and
social anxiety. Some years ago, Harris (1984) detailed a number of problems
inherent in using the lay language of “shyness” in scientific discourse, a prob-
lem that still exists today. Clinically-oriented scientists may try to “distance”
SAD from shyness, perhaps to emphasize that individuals who meet criteria
for the disorder suffer with impairment in social and occupational functioning
that can be quite terrible, leading to chronic suffering. Issues related to the ter-
minology used to describe social fears and anxieties can obfuscate the already
complex and sometimes controversial task of understanding and defining SAD
(Dalrymple, 2012). Adding further complexity, some degree of social anxiety can
be adaptive (Schneier & Welkowitz, 1996). Moreover, the social consequences of
Chapter | 1 Conceptualizing and Describing Social Anxiety 5
some socially anxious behaviors are quite positive. One example is a “bashful”
child who hides his or her face by planting it directly in a part of his or her par-
ent’s body, resulting in adult laughter and encouragement to socialize. A further
example is a distant, detached person who is regarded as “coy,” “interesting,”
or even “mysterious,” relating to his or her lack of social initiation or response.
Defining social anxieties and fears, and specifying what types or degrees
of behavior are most appropriately classified as pathological or a “disorder,” is
an involved and often perplexing undertaking. The definitions we create are in-
formed by research and clinical experience, and indeed inform future research
and clinical intervention. The National Institute of Mental Health (NIMH)
recently initiated the Research Domain Criteria project (RDoC) in an effort
to “develop, for research purposes, new ways of classifying mental disorders
based on dimensions of observable behavior and neurobiological measures”
(NIMH, 2013). Research that transcends standard diagnosing and steps away
from strict definitions of mental illness based on diagnostic criteria, such as
those presented in the DSM-5, now is preferred by the NIMH. This effort rep-
resents an understanding that the task of defining any psychological disorder
indeed is complex. SAD is no exception. Research in the area of SAD that con-
siders definitional issues and acknowledges the limits of even new diagnostic
criteria allows for a more comprehensive understanding of its psychopathol-
ogy and more appropriate translation of research findings to clinical work.
This chapter provides a perspective on conceptual, definitional, and diag-
nostic nosology issues for the field, including a focus on the DSM-5. It is pro-
posed that social anxieties and fears, like other phobic disorders, exist along
a continuum across the general population, as explicated later in this chapter,
and as shown in Figure 1.1. The range of social anxieties/fears along this con-
tinuum is from no anxiety/fear, to “normal” levels, to psychopathological ex-
tremes. The debate (e.g., Campbell-Sills & Stein, 2005; Wakefield, Horowitz,
& Schmitz, 2005a; Wakefield, Horowitz, & Schmitz, 2005b) on “overpatholo-
gizing” socially anxious people then may be somewhat addressed by a concep-
tualization that acknowledges both “normal” social anxieties that are mildly
