Myths and Facts
Myth - Child is sent to TO to think about what they did wrong.
Fact – We can’t control what a child is thinking about.
Myth – Parent should force a child to stay in TO by holding them there or locking them in a
room.
Fact – Touch is very reinforcing and locking a child in a room creates an aversive
environment and child will behave worse.
Myth – The length of time a child should be sent to TO depends on their age. If a child is 10
they should have a 10 min TO.
Fact – A 1 minute TO is just as effective as a longer TO.
Fact – An 8 minute TO is the longest a child should be in TO. Any longer and it becomes an
aversive environment and child will behave worse.

Parent Management Training and Problem-Solving
Skills Training for Child and Adolescent Conduct
Problems
Alan E. Kazdin
A great deal is known about CD in terms of correlates, risk and protective factors,
long-term course, genetic influences, and characteristics of brain activity (e.g., Lahey &
Waldman, 2012; Moffitt & Scott, 2009). For example for CD, we know that there are untoward
long-term deleterious consequences that encompass mental and physical health, substance abuse,
criminal behavior, and maladaptive functioning in everyday life (e.g., employment, managing
finances). ODD also has a poo r long term prognosis, even though this disorder has been less
well studied than has CD (Nock, Kazdin, H ir ipi, & Kessler, 2007).
For both CD and ODD, fundamental questions related to etiology and processes through
which symptoms emerge remain to be resolved. Perhaps all the more encouraging is that at this
time, several evidence-based treatments have been devised (Kazdin, 2015). These interventions
span the full range of severity from stubbornness and defiance in young children to violence
among adjudicated adolescents. This chapter reports on our work on parent management training
(PMT) and cognitive problem-solving skills training (PSST).
Our emphasis on PMT stems from two separate bodies of research: (1) the seminal
conceptual and empirical work of Patterson and his colleagues that focuses on coercive
sequences of parent- child interactions and how they can be altered (e.g., Patterson, 2016; Reid,
Patterson, & Snyder, 2002), and (2) advances in applied behavior analysis on how to change
behavior (e.g., use of establishing operations, functional analysis, differential reinforcement;
Cooper , Heron, & Heward, 2007; Kazdin, 2013). These lines of work can be translated into
multiple concrete techniques to alter both parent and child behavior.
PMT emphasizes changing how the child responds in interpersonal situations at home, at
school, and in the community and with teachers, parents, peers, siblings, and others. The
treatment uses learning -based procedures to develop behav ior and includes modeling,
prompting and fading, shaping, positive reinforcement, practice and repeated rehearsal,
extinction, and mild punishment. The treatment sessions develop skills that the parents use to
implement behavior change programs in the home.
PSST focuses on cognitive processes, a broad class of constructs that pertains to how
individuals perceive, code, and experience the world. Individuals who engage in conduct
problem behaviors, particularly aggression, show distortions and deficiencies in various
cognitive processes (e .g., Lochman, Powell, Whidby, & FitzGerald, 2012). Examples include
generating alternative solutions to interpersonal problems (e .g., different ways of handling social
situations), identifying the means to obtain particular ends (e.g., making friends) or consequences
of one's actions (e.g., what could happen after a particular behavior); making misattributions to
others of the motivation for their actions, perceiving how others feel, and expectations of the
effects of one's own actions. Deficits and distortion among these processes relate to teacher
ratings of disruptive behavior, peer evaluations, and direct assessment of overt behavior. Our
program initially drew heavily on the pioneering work of Shure and Spivack (e. g., Shure, 1992;
Spivack & Shure, 1982).
The children are referred for oppositional, aggressive, and antisocial behavior, and
usually meet criteria for a primary diagnosis (using DSM criteria) of CD or ODD.
Approximately 70% of the children meet criteria for two or more disorders (range: zero to five
disorders). Most youth fall within the normal range of intelligence (e.g., mean Full-Scale IQ=
100-105; range from 60 to 140 on the Wechsler Intelligence Scale for Children-Revised). The
families we see are European American (-60-70% across projects), African American (-10-20%),
or Hispanic American (-1-7%), Asian and Native American (-1-2% each), with multiracial
families forming the remainder. The sex ratio of boys to girls in our projects is 3-4:1.
Approximately 50% of our cases come from two-parent families; the full range of
socioeconomic and educational status is represented.
For example, in a session on attending and ignoring, parents engage in several role plays
with the therapist. Parent and therapist may alternate the role of the child and the parent. The
"child's behavior" is modeled by the therapist, who is demanding something, especially after
being told "no." The therapist whines, follows the parent who is walking away, and is demanding
to be heard and to have some parental decision overturned; the parent ignores. Once the child
calms down or begins to ask something nicely, the parent attends to the child and, depending on
the behavior, may even praise the child for calming down quickly. This is rehearsed multiple
times to help the parent practice ignoring and walking away, then return calmly to reinforce
behavior that is more appropriate on the child's part. The therapist sculpts parental behavior with
antecedents (verbally and nonverbally before and during the enactments), feedback and praise
(for small or large components of what the parent is doing), shaping, and moving to more
complex and unreasonable child behavior that mimic worst-case scenarios of the child.
TABLE 9.1. Parent Management Training Sessions: Overview of the Core Themes and
Sessions
1. Introduction and Overview. This session provides the parents with an overview of the
program and outlines the demands placed upon them and the focus of the intervention.
2. Defining ana Observing. This session trains parents to pinpoint, define, and observe
behavior. The parents and trainer define specific problems that can be observed, and
develop a specific plan to begin observations.
3. Positive Reinforcement (Point Chart and Praise). This session focuses on learning the
concept of positive reinforcement, factors that contribute to the effective application, and
rehearsal of applications in relation to the target child. An incentive ( oken/point_) chart
is devised , and _the delivery praise of the parent is developed through modeling ,
prompting, feedback , and praise by the therapist.
4. Time-Out from Reinforcement. Parents learn about time out and the factors related to its
effective application. Delivery of time out is extensively role-played and practiced.
5. Attending and Ignoring. Parents learn about attending and ignoring and choose
undesirable behavior that they will ignore and a positive opposite behavior to which they
will attend. These procedures are practiced within the session.
6. Shaping/School Intervention. Parents are trained to develop behaviors by reinforcement
of successive approximations and to use prompts and fading of prompts to develop
terminal behaviors. Also, in this session, plans are made to implement a home-based
reinforcement program to develop school-related behaviors based on consultation of the
therapist with the school.
7. Review of the Program. Observations of the previous week , as well as application of the
reinforcement program, are reviewed. Details about the administration of praise, points,
and backup reinforcers are discussed and enacted so the therapist can identify how to
improve parent performance. The parent practices designing programs for a set of
hypothetical problems.
8. * Family Meeting. At this meeting, the child and parent(s) are brought into the session.
The programs are discussed along with any problems. Revisions are made as needed to
correct misunderstandings or improve implementation.
9. and 10.* Negotiating, Contracting, and Compromising. The child and parent meet
together to negotiate new behavioral programs and to place these in contractual form. The
therapist shapes negotiating skills in the parent and child, reinforces compromise, and
provides less and less guidance as more difficult situations are presented.
11. Reprimands and Consequences for Low-Rate Behaviors. Parents are trained in effective
use of reprimands and how to deal with low-rate behaviors such as fire setting, stealing,
or truancy.
12. Review, Problem Solving , Practice, Role Reversal. Parents practice designing new
programs, revising ailing programs, and responding to a complex array of situations in
which principles and practices discussed in prior sessions are reviewed. Also, parents
pretend to be the therapist and "train" the therapist pretending to be a parent.
_____________________________________________________________________________________________________________________
Note. The complete manual and supporting materials are provided elsewhere (Kazdin, 2005). Our sessions have varied in number in different
projects. Rather than number of sessions, the content areas of this table are more critical. Those sessions with an asterisk (*) are the ones we have
not included in our recent versions of treatment.
In some of our clinical trials, the child has been brought into the PMT sessions to reenact
situations that have occurred in the home and handle new situations. With the child present, one
can directly observe parent execution of procedures and child behavior in reenactments of
situations that transpired at home. Also, we can ask the child questions that corroborate parental
report of the program in the home or suggest inconsistencies. Currently, we do not include the
child in the sessions; effective intervention has not required that. Also, scheduling children to be
part of the sessions has raised more challenges in treatment delivery, because sessions can only
be conducted after school or by taking the child out of school to attend the session.
Behavior refers to ways of crafting and obtaining the behaviors of interest and includes
three strategies. First and most straightforward is "shaping," which refers to developing goal
behavior in steps or small increments until the final goal is achieved. Second, we use simulations
in which the parent and child enact the desired behaviors under game-like circumstances. For
example, the parent and child may play something called the "tantrum game," in which the
parent pretends to deny an activity or privilege (e.g., "You cannot use the computer tonight"), the
child enacts a controlled tantrum (e .g., no hitting of the parent, breaking things, or shouting),
and then is praised for the result. This "game" can be used for many different behaviors when
shaping is not likely to be a viable option, because initial small increments of the behavior are
not present or evident with enough frequency. The "game" is a superb venue for combining
antecedents and consequences, and can readily achieve the main goal of the intervention,
repeated practice. As in other "simulations" (e.g., used by commercial airline pilots, by collegiate
and professional athletic teams) the practice carries over to everyday circumstances and may
then be directly fostered (reinforced) there. Finally, we use the game component to real-life
situations that are not quite simulations. For example, to speak nicely or without swearing, we
have used a game and challenge at the dinner table in which some contingency is in place for the
entire family. It is a game in once sense (playful, artificial, and a challenge) but also part of a
genuine everyday situation (eating dinner together). Shaping can be incorporated into the game
as needed to develop behavior gradually.
Consequences also include a token reinforcement or point system in the home to provide
a structured way of implementing the reinforcement contingencies. Our use of tokens is not so
much for the child as it is for the parents. Parents are more likely to carry out the praise program
when the structure and requirements of a point chart are used (e.g., monitoring delivery,
accumulation, and use of points). Also, tokens facilitate tracking of reinforcement exchanges
between parent and child (earning and spending the tokens). If behavior changes are needed at
school (e.g., deportment, homework completion), we consult with teachers. A home-based token
reinforcement system is devised in which child performance at school is monitored (e.g., via
e-mail, phone) with consequences provided at home by the parents (see Kazdin, 2013).
Central to treatment is developing the use of problem-solving steps that serve as verbal
prompts the children deliver to themselves to engage in thoughts and actions that guide behavior.
The steps or self-statements include (1) "What am I supposed to do?"; (2) and (3) "I need to
figure out what to DO and what would HAPPEN"; (4) "I need to make a choice"; and (5) "I need
to find out how I did." Combining steps 2 and 3 requires the child to identify a solution (what to
DO) and then the consequence (what would HAPPEN), and to do this with three or more
solutions before proceeding to step 4. Using the steps, identifying and selecting prosocial
solutions, and enacting these solutions in the sessions, are modeled and practiced extensively.
Over the course of treatment, the steps move from overt (made aloud) to covert (silent, internal)
statements.
The early sessions use simple tasks and games to teach the problem-solving steps and to
help to deter impulsive responding. The content moves to individualized problem domains of the
child (e.g., interactions with peers, parents, siblings, teachers, and others), with multiple
instances and varied situations to help to promote generalization and maintenance. Throughout,
the therapist prompts the child verbally and nonverbally to guide performance, provides a rich
schedule of praise, delivers concrete feedback for performance, and models improved ways of
performing.
1. Introduction and Learning the Steps. This initial session teaches the problem-solving
steps in a game-like fashion in which the therapist and child take turns learning the
individual steps and placing them together in a sequence .
2. and 3. Applying the Steps. The child applies the steps to simple problem situations
presented in a board game in which the therapist and child alternate turns. A series of
super solvers (homework assignments) begins at this point, in which the steps are used in
increasingly more difficult and clinically relevant situations as treatment continues.
4. Applying the Steps and Role Playing. The child applies the steps to identify solutions and
consequences in multiple problem situations. Then the preferred solution, based on the
likely consequences, is selected and then enacted through repeated role-plays.
5. Parent - Child Contact. The parent(s), therapist, and child are seen in the session. The
child enacts the steps to solve problems. The parents learn more about the steps and are
trained to provide attention and contingent praise for the child's use of the steps and for
selecting and enacting prosocial solutions.
6. through 11. Continued Applications to Real-Life Situations . The child uses the
problem-solving steps to generate prosocial solutions to provocative interpersonal
problems or situations . Each session concentrates on a different category of social
interaction that the child might realistically encounter (i.e. , peer s, parents , siblings,
teachers ). Real-life situations, generated by the child, parent, or from contacts with
teachers and others, are enacted; hypothetical situations are also presented to elaborate
themes and problem areas of the child (e.g ., responding to provocation, fighting, being
excluded socially, being encouraged by peers to engage in antisocial behavior). The
child's super solvers also become a more integral part of each session; they are reenacted
with the therapist beginning in session in order to better evaluate how the child is
transferring skills to his or her dai ly environment.
12. Wrap -Up and Role Reversal. This "wrap-up " session is included (a) to help the therapist
generally assess what the child has learned in the session, (b) to clear up any remaining
confusions the child may have concerning the use of the steps, and (c) to provide a final
summary for the child of what has been covered in the meetings. The final session is
based on role reversal in which the child plays the role of the therapist and the therapist
plays the role of a child learning and applying the steps.
____________________________________________________________________________
Children begin each session with tokens (small plastic chips) that can be exchanged for
small prizes at a "store" after each session . During the session, children can lose chips (response
cost) for misusing or failing to use the steps or gain a few additional chips, although this rarely
occurs. Social reinforcement and extinction are relied on more than token reinforcement to alter
child behavior. The chips present opportunities to address special issues or problems with the
child, such as encouraging a particular type of prosocial solution that the child might find
difficult.
For PSST, we have provided a summary of the treatment sessions and key steps in
developing use of the problem-solving skills steps, how these are applied and enacted within the
sessions, how they are faded over time, and homework assignments as children apply the skills
in everyday life ( http:// yalepa ren tingcenter.yale.edu/ store). We have not published a detailed,
session-by-session manual or supporting materials beyond what is conveyed in the overview.
Among the reasons has been our emphasis on PMT within our clinical service.

Note. The table includes studies that had treatment outcome as the major focus. Many of our other studies are cited in the text on related topics (e.g.,
participation in treatment) and are not included here.
Outcome Effects
PMT and PSST alone or in combination produce reliable and significant reductions in
oppositional, aggressive, and antisocial behavior, and increases in prosocial behavior among
children. Parent dysfunction (depression, multiple symptom domains) and stress decline and
family relations improve (Kazdin, Bass, Siegel, & Thomas, 1989; Kazdin, Esveldt-Dawson,
French, & Unis, 1987a, 1987b; Kazdin, Siegel, & Bass, 1992). The effects of PMT can be
enhanced by providing supplementary sessions that focus on parent sources of stress (Kazdin &
Whitley, 2003). Also, a motivational enhancement intervention can improve parent motivation
for, adherence to, and attendance of treatment (Nock & Kazdin, 2005). Computer based delivery
of PMT and reduced contact with a therapist have been as effective as PMT delivered in person
(Rabbitt et al., 2016).
Moderators of Treatment
Several characteristics of parents and children, beyond alliance, moderate therapeutic
change, including severity of child dysfunction, child IQ, parent stress, parent psychopathology,
and others. The most robust moderator of our treatment has been parental report of barriers to
participation in treatment. These barriers reflect four areas: stressors that compete with
participating in treatment, perceived treatment demands, perceived relevance of treatment, and
obstacles in relation to the therapist. The higher the perceived barriers, whether evaluated by
parents or therapists, the less the therapeutic change among the children, a relation not accounted
for by other factors, such as severity of parent or child dysfunction, stress in the home, or parent
attendance to treatment (Kazdin, 1995; Kazdin & Crowley, 1997; Kazdin, Holland, & Crowley,
1997; Kazdin, Holland, Crowley, & Breton, 1997; Kazdin & Wassell, 1999, 2000a, 2000b;
Kazdin & Whitley, 2006a).
Participation in Treatment
Parent dysfunction, family stress, and the experience of barriers to participation in
treatment are among the more robust predictors of canceling and not showing up for sessions,
and dropping out early. Dropping out early does not necessarily mean failure in treatment.
Among those who drop out of treatment very early, 34% report large improvements in the
behavior of their children (Kazdin, 1990; Kazdin & Mazurick, 1994; Kazdin, Mazurick, & Bass,
1993; Kazdin, Mazurick, & Siegel, 1994; Kazdin, Stolar, & Marciano, 1995; Kazdin & Wassell,
1998 ). Indeed , in many instances, individuals convey that they are dropping out because they
perceive no need to continue and complete our planned regimen.
Overall, our work has shown that PSST and PMT can effect significant change in
severely disturbed children referred for inpatient or outpatient treatment. Effects of treatment are
evident in performance at home, at school , and in the com mu nit y, both immediately after
treatment and up to a I-year follow-up assessment. Symptoms levels at the end of treatment often
fall within a sex- and age-based normative range.
Second, core procedures that are used in PMT have been applied widely to other domains
of clinical dysfunction in children and adults (e.g., autism spectrum disorders, anxiety disorders,
addictive behaviors, psychoses) and well beyond clinical work. For example, the procedures
have been effectively applied to diverse domains of functioning (e.g., classroom behavior,
reading and writing , athletic performance, recycling and energy conservation, basic training in
the military, gambling, engaging in social activities, adhering to medical regimens, engaging in
exercise), to a wide age range (from toddlers through older adults), and in multiple contexts (the
home, schools, colleges, business and industry, hospitals, the community) (Cooper et al., 2007;
Kazdin, 1977, 2013).
Finally, basic human and nonhuman animal research spanning decades has elaborated
operant conditioning principles and techniques from which PMT procedures draw. Seminal
nonhuman animal research has provided extensive data on core facets of learning and
performance (e.g., schedules of reinforcement, extinction , punishment) that are central to PMT
(e.g., Azrin & Holz, 1966; Ferster & Skinner, 1957). With only broad brush strokes here, it is
might be reasonable to claim that PMT and the techniques on which it is based are without peer
in the supportive evidence from which they can draw.
FUTURE DIRECTIONS
There is an enormous treatment gap (i.e., the gap between how many people are in need
of treatment [prevalence] and those who actually receive treatment). This applies to not only
disruptive behavior disorders, which has been the focus of this chapter, but also to psychiatric
disorders more generally. The vast majority of individuals (children, adolescents, and adults)
who are in need of services receive no services at all. Consequently, a high priority for future
research is to extend treatments to reach more people in need of services. One area worth special
research emphasis in PMT might be greater use of technology and social media (apps, the Web,
texting, Facebook) to extend the intervention on a much larger scale than what is being
accomplished now. The use of the Web, as one option, provides huge potential in extending the
reach of evidence-based psychotherapies. An exemplary illustration was a large-scale Web-based
intervention for smoking cessation that reached over 290,000 individuals from 168 countries
(Munoz et al., 2016). A research priority would be to extend PMT to more people in need and to
evaluate whether favorable outcomes can be achieved at that scale.
Another priority area would be to deliver and evaluate PMT as a tool for parenting in
general rather than, or at least in addition to, a clinical intervention. "Normal" parenting often is a
challenge , and PMT provides tools that can help with these challenges (e.g ., children eating
vegetables, practicing a musical instrument, doing homework, or teens communicating without
sarcasm, eye rolling, and visible disgust because they are in the presence of a parent). Broad
application may prevent or reduce deleterious parenting practices (e.g., use of corporal
punishment). Making PMT more widely available to all parents in a user-friendly fashion would
be a major contribution to treatment, prevention, and family harmony.
CONCLUDING COMMENTS
We have evaluated PMT and PSST with a range of child samples, including inpatient and
outpatient cases. Among all of our samples, children show multiple disorders and usually
multiple risk factors for continued dysfunction. As might be expected , the child problems often
are embedded in contexts that include parent sources of dysfunction, stress, and family issues
(e.g., domestic violence, socioeconomic disadvantage). Our interventions have produced reliable
changes in child behavior at home, at school, and in the community, even among the most
severely impaired cases and in complex family situations. In addition, we find decreases in
parent depression and stress, and improvements in family relations. Making concrete changes in
how the children function in everyday life appears to have positive collateral effects on the
parents and family.
Our most recent work has focused on making PMT more accessible and applicable
clinically by reducing the amount of professional therapist time that is required and delivering
treatment online. Our initial evidence suggests no loss of treatment efficacy with these changes.
These findings are in keeping with those of others who have extended PMT in ways that go
beyond individual, in-person treatment. From the work of many researchers, including those with
chapters in this book, PMT is one of the more well-studied interventions with a strong
experimental and applied research base. The challenges are extending this on a scale that makes
a difference in society, in addition to the lives of individual children and their families.

ABSTRACT
ObJective: To describe and evaluate parent management training (PMT) as a treatment technique for oppositional,
aggressive, and antisocial behavior. Method: Recent research is reviewed on the efficacy of PMT; factors that contribute
to treatment outcome; the range of outcomes related to child, parents, and family; and variations of treatment currently in
use. Limitations are also discussed related to the impact of treatment, clinical application, and dissemination of treatment.
Results and Conclusions: PMT is one of the more well·lnvestigated treatment techniques for children and adolescents.
Notwithstanding the large number of controlled studies attesting to its efficacy, fundamental questions remain about the
magnitude, scope, and durability of impact. J. Am. Acad. Child Ado/esc. Psychiatry, 1997, 36(10) :1349-1356. Key Words:
