Behavioral assessment of impulsivity: a comparison of children with and without attention deficit hyperactivity disorder

We conducted a brief computer-based assessment involving choices of concurrently presented arithmetic problems associated with competing reinforcer dimensions to assess impulsivity (choices controlled primarily by reinforcer immediacy) as well as the relative influence of other dimensions (reinforcer rate, quality, and response effort), with 58 children. Results were compared for children with attention deficit hyperactivity disorder (ADHD) who were and were not receiving medication, and with typically developing children without ADHD. Within-subject and between-groups analyses of the ordinal influence of each of the reinforcer dimensions were conducted using both time- and response-allocation measures. In general, the choices of children with ADHD were most influenced by reinforcer immediacy and quality and least by rate and effort, suggesting impulsivity. The choices of children in the non-ADHD group were most influenced by reinforcer quality, and the influence of immediacy relative to the other dimensions was not statistically significant. Results are discussed with respect to the implications for assessment and treatment of ADHD.     

Marital Conflict Among Parents: Implications for Family Therapy with Adolescent Conduct Disorder

Conduct disorder is associated with several causative and maintaining factors, with family functioning being an important one. This is especially true in the Indian context, where a lot of the problem behaviors manifested by adolescents with conduct disorders are in the family context. Marital relationship of the parents is a key aspect of family functioning, affecting a number of other dimensions of family functioning, including adolescent adjustment. The paper highlights the role of parents’ marital conflict in the emergence and maintenance of adolescent conduct problems. The importance of family therapy in managing adolescent conduct disorder is discussed through case examples from India.

Understanding the Covariation Among Childhood Externalizing Symptoms: Genetic and Environmental Influences on Conduct Disorder,Attention Deficit Hyperactivity Disorder,and Oppositional Defiant Disorder Symptoms

Conduct disorder (CD), attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD) are common childhood externalizing disorders that frequently co-occur. However, the causes of their comorbidity are not well understood. To address that question, we analyzed data from > 600 Finnish twin pairs, who completed standardized interviews at age 14. Behavior genetic methods were used to examine how genetic/environmental factors contribute to each disorders symptoms and to their covariation. We found significant genetic effects on each disorder with only modest evidence of shared environmental influences. Our data suggest the comorbidity among CD, ADHD, and ODD is primarily explained by shared genetic influences; however, each disorder was also under unique genetic influence, supporting the distinction of each disorder.     

Psychosocial Issues That Face Patients With Charcot-Marie-Tooth Disease: The Role of Genetic Counseling

Charcot-Marie-Tooth (CMT) disease is a hereditary debilitating progressive muscular atrophy and sensory neuropathy of the distal extremities. CMT is usually nonlife threatening. Signs of the disease usually present in childhood or in young adulthood and the level of disability can be variable within and between families. Research addressing specific psychosocial and emotional issues faced by individuals with CMT is limited. Fourteen adults with a clinical and/or molecular diagnosis of CMT (ages 32–74 years) consented to an audio taped interview. The format of the interview was based around an informal questionnaire to prompt and guide the interviewee to describe their experiences of living with a disabling genetic disorder. The interviews focused on their experiences of first symptoms and diagnosis, their life experience with CMT, their limitations due to disability and the role of genetic counseling. This study identifies and explores life issues that individuals with CMT may face, specifically grief over the loss of independence, emotional pain and stress such as embarrassment and guilt of passing on a gene mutation, impact on quality of life, the impact of wearing orthopedic devices, and fear of progressive disability. Our findings suggest that that there are emotional and psychosocial issues specific to affected individuals at different life stages and genetic counselors need to be aware of these issues in order to provide age appropriate support and advice to individuals affected by CMT.     

Interpersonal Relationships and Sex Differences in the Development of Conduct Problems

This article investigates the role of interpersonal relationships in shaping sex differences in the manifestation, etiology, and developmental course of conduct problems and their treatment needs. The review examines whether: (1) Girls conduct problems are more likely than boys to manifest as a function of disrupted relationships with caretakers and peers; (2) For girls more than for boys, the outcomes of conduct problems in adolescence and adulthood, and related treatment needs, are more likely to be a consequence of the quality of interpersonal relationships with others, particularly opposite-sex peers and partners. Evidence reviewed suggests that boys and girls share many similarities in their expression of conduct problems, but that a relational perspective does unify important differences. There is fair evidence that girls with conduct problems are more likely to come to the attention of authorities because of chaotic, unstable family relationships, and to express antisocial behavior in the context of close relationships; there is stronger evidence that the course and outcomes of conduct problems in females versus males pertain to interpersonal relationship impairments. Those sex differences map onto specific differences in treatment needs. Further empirical testing of the proposed relational model is indicated.     

Social anxiety in body dysmorphic disorder

Although clinical impressions suggest that patients with body dysmorphic disorder (BDD) experience distress in social situations, social anxiety in BDD has received little investigation. This study examined social anxiety in 81 patients with BDD and change in social anxiety with pharmacotherapy. Subjects completed the Social Avoidance and Distress Scale (SADS) and were assessed with measures of BDD symptomatology. Participants in a placebo-controlled fluoxetine trial completed measures at baseline and endpoint. The mean SADS score was 1.3 SD units higher than nonclinical sample means but consistent with other clinical sample means. Social anxiety was significantly correlated with BDD severity. Greater depressive symptoms as well as comorbid avoidant personality disorder, but not comorbid social phobia, were also associated with higher SADS scores. Social anxiety did not improve more with fluoxetine than placebo, yet it improved significantly more in fluoxetine responders than in nonresponders. Understanding social anxiety in BDD has implications for reducing rates of misdiagnosis and treatment dropout.     

Exploring adolescent social media and internet gaming addiction: The role of emotion regulation

Behavioral addictions such as social media addiction and internet gaming disorder are prevalent among adolescent populations. Although studies have investigated predictors of these addictive behaviors with international samples of adolescents, less is known about American adolescents. In this study, we investigated the predictive nature of emotion regulation after controlling for age, gender, and race with regard to social media addiction and internet gaming disorder severity. Results indicate that gender and emotion regulation significantly predicted both forms of behavioral addictions with small to moderate effects. Specifically, female gender and lower emotion regulation significantly predicted social media addiction and male gender and lower emotion regulation significantly predicted internet gaming disorder severity. Implications for mental health professionals are discussed.

Evaluation of a break-to-choice chained-schedule intervention for multiply maintained problem behavior

Interventions for multiply maintained problem behavior often involve developing separate treatment conditions to address each function. Although isolating treatment conditions lead to positive outcomes, developing individual treatments for each identified function may be time-consuming. Alternatively, synthesizing treatment procedures may allow for more efficient treatment effects. We extended previous research by evaluating functional communication training (FCT) and chained schedules of reinforcement to treat multiply maintained problem behavior in children diagnosed with autism spectrum disorder. First, we conducted a functional analysis that concluded problem behavior was multiply maintained. Next, we taught functional communication responses (FCRs) and implemented a chained schedule of reinforcement. During the initial link, FCRs for a break resulted in the presentation of a choice menu with the other putative reinforcers in the terminal link. The relevant reinforcer was delivered contingent on the emission of subsequent FCRs. Finally, we systematically schedule thinned to caregiver-informed terminal schedules for each participant. The results of our study demonstrated that FCT, in combination with a sequential compound schedule of reinforcement, effectively decreased multiply maintained problem behavior and increased appropriate alternative responses (FCRs and compliance) even at terminal schedules of reinforcement.     

Implementing a differential reinforcement of low rates schedule to alter vocal stereotypy and task engagement in two adolescents with autism spectrum disorder

Vocal stereotypy (VS) is often observed in individuals with autism spectrum disorder (ASD) which at high rates can interfere with socialization or functioning in structured settings. There are multiple effective interventions available; yet, many procedures target the complete omission of the behavior or are only assessed at short intervals, making it unclear how they will generalize in applied settings. One intervention yet to be assessed as an individual intervention for automatically reinforced VS is differential reinforcement of low rates of behavior (DRL). In the present study, a functional analysis determined that the VS of two female adolescents with ASD was maintained by automatic reinforcement. A DRL procedure was implemented which incorporated: (a) a specified interval for reinforcement; (b) the behavioral expectations; (c) the permissible instances of VS within the interval; (d) learner feedback; and (e) the reset/non-reset aspect of the schedule. As the targeted behavior decreased across sessions, the DRL interval was systematically increased in order to thin out the schedule of reinforcement. The intervention reduced VS and increased untargeted task engagement for both participants. Applied and theoretical implications of the study as well as social validity, limitations, and future research are discussed.
