A Note From the Publisher

Introduction
Contemporary family psychology is a complex and vast field. At its core, it is a way of
approaching human behavior, including problematic behavior, from a systemic perspec-
tive. It encompasses a worldview that human behavior can be understood by simultane-
ously considering social, economic, and cultural contexts; interpersonal and intrapersonal
factors; and macrosystemic influences (Robbins, Mayorga, & Szapocznik, 2003; Stanton,
2009). Thus, to create a handbook reflecting the state of the field requires a broad vision
and systemic lens. We are delighted to introduce the APA Handbook of Contemporary
Family Psychology, which has been a labor of love and commitment by the editors.
We think this handbook is unique in several regards. The first is its comprehensive
breadth and depth: The three-volume set lays a solid foundation for integrating theory,
research, practice, and policy. Second, the scope of the handbook includes topics not
typically covered in family psychology texts but which nonetheless intersect with
family psychology in larger systems, such as the legal system, military system, and
school systems. Third, the handbook describes the role that family psychology plays in
addressing grand societal issues, such as immigration, domestic violence, and homeless-
ness. We contend that family psychology has evolved to have a major impact not only
on the practice of psychology but also on how researchers in the field investigate the
complexities of the human condition.
As noted, the handbook is organized into three volumes. The opening volume exam-
ines the theories, methods, lifespan perspectives, and wide array of family forms repre-
sented in the research literature and in family psychology policy and practice. The first
part of Volume 1 provides an overview of the origins of the field and reflects its multi-
disciplinary scope. Highlighting the psychodynamic, developmental, ecological, and
behavioral roots of family psychology, these chapters display the discipline’s theoretical
foundations. The second part of Volume 1 includes contemporary theoretical models
that demonstrate the various ways that theory has guided expansion of the field from
its psychodynamic and systemic origins to incorporate contemporary issues, including
gene–environment interactions and social neuroscience.
The third part of Volume 1 presents established and emerging research methodologies
in family psychology. Because the field focuses on relationships and how relationships
change over time, complex research designs are required, including longitudinal analy-
sis and the analysis of dyadic, nested data. The chapters in this section offer guidance
to researchers on how to conduct observational studies, complex statistical modeling,
and experience sampling, to name a few subjects. These chapters will likely be excellent

Introduction
resources for researchers beyond the field of family psychology and will help guide a
more systemic view of data collection and analysis overall.
The fourth part of Volume 1 provides a lifespan approach to family psychology, recogniz-
ing the importance of addressing how families change over time, beginning with relation-
ship initiation and couple formation and extending through the transition to parenthood,
parenting of adolescents, and later life, including loss and bereavement. These chapters
offer a snapshot of how different stages of family life bring their own unique challenges as
well as rewards. A unique addition to this section is the inclusion of a chapter on grandpar-
ents and families at midlife—two frequently overlooked developmental phenomena.
The final section of Volume 1 addresses the changing forms of and challenges faced
by contemporary families. Topics include cohabitation; separation and divorce; remarriage;
adoption; lesbian, gay, bisexual, transgender, and queer (LGBTQ) families; foster fami-
lies; and military families. While the authors of these chapters recognize that there may
be overlap across these topics (e.g., LGBTQ families also experience separation and
divorce), they provide an in-depth analysis of the challenges and transitions that differ-
ent types of families face that can inform practice and policy.
Volume 2 focuses on the application of family psychology to different health condi-
tions, systems, and societal issues. Family psychology has a long tradition of addressing
mental and physical health attributes. The chapters in this volume also address new
areas of influence, such as relational impacts on sleep and stress.
The first part of the volume describes the application of family psychology to mental
and physical health issues, including psychopathology, mood disorders, bipolar dis-
orders, antisocial disorders, pediatric chronic conditions, HIV, stress, gerontology and
caregiving, and sleep. The second part of Volume 2 provides an overview of how family
psychology intersects with broader systems. Increasingly, a systemic view is being
applied by family psychologists, as they become embedded in larger networks and
contexts. The larger systems addressed in this section include health care, schools and
after-school programs, early care and education, juvenile justice, legal systems, religious
organizations, food assistance programs that serve vulnerable families, community-
based organizations, the media, and the workplace. Readers will grasp the wide influ-
ence that family psychology is having in modern society.
The third part of Volume 2 focuses on how family psychology addresses societal
grand challenges. Extending the application of a systemic framework to human prob-
lems, many family psychologists have turned their research, practice, and policy efforts
to address some of the grand challenges faced by society today. These include intimate
partner violence, gaining cultural understanding of families, immigration, economic
strain, child abuse and neglect, bullying, incarcerated parents, homelessness, traumatic
stress, natural disasters, community tragedy and terrorism, and substance use.
The second volume concludes with a discussion of the broad reach of contemporary
family psychology. Topics include the global impact of family psychology, international
family psychology, advocacy, public health perspectives, and public policy applications.
Chapters in this section show how the family psychology system lens has been used suc-
cessfully to enact policy changes at the local, community, national, and international levels.
Volume 3 addresses contemporary couple, family, and parenting interventions
grounded in family psychology theory and science, as well as issues related to family
psychology training. The first part of the volume provides an overview of the history of
the field, relational diagnosis, guides for screening and assessment, ethics, and evaluat-

Introduction
ing efficacy in treatment. This overview sets the stage for more detailed chapters on
family and couple therapy in the second, third, and fourth parts of the volume. These
chapters not only provide up-to-date summaries of commonly used family therapies
(e.g., structural, functional, multifamily group) and couple therapies (e.g., behavioral,
cognitive behavioral, relationship education) but also focus on effective parenting pro-
grams (e.g., The Incredible Years®, Coping Power, Family Check-Up). These substantive
chapters will be invaluable resources for trainees as well as seasoned therapists.
The final part of Volume 3 presents topics relevant to competency-based education,
training, and credentialing in the specialty of couple and family psychology. These
topics are especially timely given the American Psychological Association’s new guide-
lines for the preparation and training of health service psychologists (Health Service
Psychology Education Collaborative, 2013). The authors of these chapters have played
leadership roles in the development of these guidelines and have provided clear guid-
ance to advance the field.
The chapter authors in this handbook represent a “who’s who” of the field. They
include past presidents of the American Psychological Association, past presidents of
the Society for Family Psychology, current and past editors of the Journal of Family
Psychology and Family Process, and contributors to many other associations and pub-
lication outlets. It is interesting to review the diversity of their academic disciplinary
appointments, as it reflects the broad impact of the field and its increasingly inter
disciplinary and transdisciplinary nature. Although most of the authors are housed in
departments of psychology, many are in medical schools, interdisciplinary research
centers, and policy institutes.
Because of the vast scope of the handbook, we anticipate that the audience will be
large and varied as well. In addition to graduate students in family, clinical, social, and
developmental psychology, we expect that advanced students in human development
and family studies, education, social work, public health, pediatrics, and family medi-
cine will find many of these chapters of interest. Seasoned researchers will find the
chapters on theory, methods, and applications “go to” resources for teaching as well as
guidance in their own research programs. Similarly, policymakers will find many of the
application and policy chapters to be invaluable resources as they seek supporting
evidence to propose important policies that affect children, youth, and families.
There are many people who influenced this compilation. We would like to acknowl-
edge Dr. Anne Kazak, who originally proposed this handbook; her guidance, as well
as contributions to the field, have been invaluable. Kristen Knight at the American
Psychological Association has been patient and resourceful throughout the editorial pro-
cess and we are forever grateful to her. We also acknowledge the patience and support
of our families, who tolerated the birthing of this project that lasted into toddlerhood.
Many a weekend was spent on editing chapters that could have been spent on family
activities. To them, we owe our gratitude.
