Familial Aggregation of ADHD Characteristics

Patterns of familial aggregation of ADHD symptoms in parents of ADHD and non-ADHD children were examined. Within the ADHD sample, symptom aggregation was examined as a function of biological relationship, parent and child gender, and children's comorbid diagnoses. Participants consisted of parents of 579 children with ADHD, Combined Type participating in the multimodal treatment study of children with ADHD and parents of 288 normal control participants. Adult symptoms of ADHD were measured by both self-report and report of a significant other. Results indicated that the parents of children with ADHD had higher ratings of inattention/cognitive problems, hyperactivity/restlessness, impulsivity/emotional lability, and lower self-concept than parents of children without ADHD on both self-report and other-report ratings. Within the ADHD sample of children, other-report ratings of inattention/cognitive problems and impulsivity/emotional lability were higher for biological parents compared to nonbiological parents whereas self-ratings were not related to biological status. These findings support previous research documenting familial aggregation of ADHD and appear to strengthen the hypothesis that there is a genetic contribution to ADHD.     

Anxiety as a Predictor and Outcome Variable in the Multimodal Treatment Study of Children with ADHD (MTA)

Initial moderator analyses in the Multimodal Treatment Study of Children with ADHD (MTA) suggested that child anxiety ascertained by parent report on the Diagnostic Interview Schedule for Children 2.3 (DISC Anxiety) differentially moderated the outcome of treatment. Left unanswered were questions regarding the nature of DISC Anxiety, the impact of comorbid conduct problems on the moderating effect of DISC Anxiety, and the clinical significance of DISC Anxiety as a moderator of treatment outcome. Thirty-three percent of MTA subjects met DSM-III-R criteria for an anxiety disorder excluding simple phobias. Of these, two-thirds also met DSM-III-R criteria for comorbid oppositional-defiant or conduct disorder whereas one-third did not, yielding an odds ratio of approximately two for DISC Anxiety, given conduct problems. In this context, exploratory analyses of baseline data suggest that DISC Anxiety may reflect parental attributions regarding child negative affectivity and associated behavior problems (unlike fearfulness), particularly in the area of social interactions, another core component of anxiety that is more typically associated with phobic symptoms. Analyses using hierarchical linear modeling (HLM) indicate that the moderating effect of DISC Anxiety continues to favor the inclusion of psychosocial treatment for anxious ADHD children irrespective of the presence or absence of comorbid conduct problems. This effect, which is clinically meaningful, is confined primarily to parent-reported outcomes involving disruptive behavior, internalizing symptoms, and inattention; and is generally stronger for combined than unimodal treatment. Contravening earlier studies, no adverse effect of anxiety on medication response for core ADHD or other outcomes in anxious or nonanxious ADHD children was demonstrated. When treating ADHD, it is important to search for comorbid anxiety and negative affectivity and to adjust treatment strategies accordingly.     

Sitting In: The Experience of Learning and Practicing Family Therapy through Being a Co-Therapist in Hong Kong

This article explores family therapy trainees’ subjective experiences of working as cotherapists with a supervisory-level therapist in a Chinese context, regarding their perceptions of and positioning in it and also their opinions on the benefits and/or pitfalls of cotherapy. Individual interviews with a total of six cotherapists revealed three themes: (1) Cotherapy was perceived as an experiential learning journey that evolved from anxiety and excitement to empowerment and nurturing; (2) a collaborative master–apprentice relationship of openness, trust, and mutual respect was developed with both sides’ interactive effort, which included common commitment and concern for the client, the supervisor’s awareness and explicit address of the role hierarchy, principle setting prior to the cooperation, and honest pre- and-postsession sharing and discussion; (3) the dual-purpose supervisor–trainee cotherapy brought direct benefits for all involved parties and for others. The findings have useful implications for integrating treatment and training for optimal training/learning outcomes and for advancing knowledge transfer from senior to junior and from academia to the field, with reference to local cultural characteristics.     

Associative learning versus fear habituation as predictors of long-term extinction retention

Violation of unconditioned stimulus (US) expectancy during extinction training may enhance associative learning and result in improved long-term extinction retention compared to within-session habituation. This experiment examines variation in US expectancy (i.e., expectancy violation) as a predictor of long-term extinction retention. It also examines within-session habituation of fear-potentiated startle (electromyography, EMG) and fear of conditioned stimuli (CS) throughout extinction training as predictors of extinction retention. Participants (n?=?63) underwent fear conditioning, extinction and retention and provided continuous ratings of US expectancy and EMG, as well as CS fear ratings before and after each phase. Variation in US expectancy throughout extinction and habituation of EMG and fear was entered into a regression as predictors of retention and reinstatement of levels of expectancy and fear. Greater variation in US expectancy throughout extinction training was significantly predictive of enhanced extinction performance measured at retention test, although not after reinstatement test. Slope of EMG and CS fear during extinction did not predict retention of extinction. Within-session habituation of EMG and self-reported fear is not sufficient for long-term retention of extinction learning, and models emphasizing expectation violation may result in enhanced outcomes.     

The importance of laughing in your face: influences of visual laughter on auditory laughter perception

Hearing the sound of laughter is important for social communication, but processes contributing to the audibility of laughter remain to be determined. Production of laughter resembles production of speech in that both involve visible facial movements accompanying socially significant auditory signals. However, while it is known that speech is more audible when the facial movements producing the speech sound can be seen, similar visual enhancement of the audibility of laughter remains unknown. To address this issue, spontaneously occurring laughter was edited to produce stimuli comprising visual laughter, auditory laughter, visual and auditory laughter combined, and no laughter at all (either visual or auditory), all presented in four levels of background noise. Visual laughter and no-laughter stimuli produced very few reports of auditory laughter. However, visual laughter consistently made auditory laughter more audible, compared to the same auditory signal presented without visual laughter, resembling findings reported previously for speech.     

Treatment Efficacy of Multiple Family Therapy for Chinese Families of Children with Attention Deficit Hyperactivity Disorder

The treatment efficacy of multiple family therapy (MFT) for Chinese families of children with attention deficit hyperactivity disorder (ADHD) has not been studied in the past. In this paper, the effect of MFT on different aspects of the lives of the parents in the experimental group (n = 61) was compared with the effect of only the psychoeducational talks on parents in the control group (n = 53). The results of a MANOVA have shown that by the time they reached the posttreatment phase, the parents who had completed the full 42 hours of the MFT program perceived their children's ADHD symptoms as being less serious and less pathological than they had originally thought compared to the parents in the control group. The effect of MFT on parent–child relationships, parenting stress, parental efficacy, hope, and perceived social support was statistically insignificant. Contributions and limitations of our study are discussed.
