Self-esteem in patients with borderline and avoidant personality disorders

This study compared self-esteem in patients with avoidant personality disorder (APD) and borderline personality disorder (BPD). Patients diagnosed with one or more personality disorders answered the questionnaire Index of Self Esteem as part of a comprehensive evaluation within the setting of a treatment trial. Our hypotheses were that (1) both patients with APD and patients with BPD would report low levels of self-esteem, (2) patients with APD would report lower self-esteem than patients with BPD. We further expected that (3) patients with higher levels of depression would report lower levels of self-esteem, but that (4) both borderline and avoidant personality pathology would contribute to explained variance in self-esteem beyond what would be accounted for by depression. All of our hypotheses were supported. The results from our study showed a significant difference in self-esteem level between the two personality disorders, patients with APD reporting lower self-esteem than patients with BPD. Subjects with both disorders were measured to have self-esteem levels within the range that presumes clinical problems. Self-esteem represents an important quality of subjective experience of the self, and the study of self-esteem in PDs can offer new and important knowledge of PDs as self-pathology.     

Associations between Maternal Attention-Deficit/Hyperactivity Disorder Symptoms and Parenting

Mothers of children with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for an ADHD diagnosis themselves, which is likely associated with impairments in parenting. The present study utilized a multi-method assessment of maternal ADHD and parenting to examine the extent to which maternal ADHD symptoms are associated with maladaptive parenting. Participants included 70 6–10 year old children with DSM-IV ADHD and their biological mothers. Results suggested that mothers with higher levels of ADHD symptoms reported lower levels of involvement and positive parenting and higher levels of inconsistent discipline. During observed parent–child interactions, maternal ADHD symptoms were negatively associated with positive parenting, and positively associated with negative parenting and repeated commands before giving the child an opportunity to comply. Given prior research suggesting that maladaptive parenting behaviors are risk factors for the later development of conduct problems among children with ADHD, these findings have important clinical implications for family-based assessment and treatment of ADHD.     

Test of Alternative Hypotheses Explaining the Comorbidity Between Attention-Deficit/Hyperactivity Disorder and Conduct Disorder

There is significant comorbidity between attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD). The conclusions of studies that examined the causes of comorbidity between ADHD and CD conflict, with some researchers finding support for the three independent disorders model and others finding support for the correlated risk factors model. We tested these models and eleven alternative hypotheses using the same analytical approach. The participants were 110 monozygotic twin pairs and 181 dizygotic twin pairs recruited from the Colorado Learning Disabilities Research Center Twin Study. The three independent disorders model did not fit the data, whereas the correlated risk factors model fit the data well. Several other comorbidity models fit the data as well as or better than the correlated risk factors model. The results suggest that correlated risk factors are a better explanation for the comorbidity between ADHD and CD than a third, independent ADHD+CD subtype.     

Response Style Differences in the Inattentive and Combined Subtypes of Attention-Deficit/Hyperactivity Disorder

This study examined potential differences between the inattentive and combined ADHD subtypes using laboratory tasks assessing behavioral inhibitory processes. Seventy-five children completed two tasks of behavioral inhibition believed to isolate different processes: the cued reaction time task (CRT), a basic inhibition task, and the go/no-go task (GNG), a complex inhibition task that incorporates motivational contingencies. Three groups of participants were identified, including ADHD/Inattentive (n = 17), ADHD/Combined (n = 37), and comparison (n = 21). Results indicated that rather than showing behavioral inhibition deficits, the ADHD/I children appeared overly inhibited, as evidenced by slower reaction times across the two tasks and significantly higher errors of omission in the GNG task. Additionally, the ADHD/I children did not demonstrate cue dependency effects on the CRT task, suggesting that they were failing to incorporate relevant information before making a response. The sluggish and inhibited performance of the ADHD/I group challenges the idea that it is a subtype of ADHD.     

Common Genetic and Environmental Influences on Major Depressive Disorder and Conduct Disorder

The evidence for common genetic and environmental influences on conduct disorder (CD) and major depressive disorder (MDD) in adolescents was examined. A sample of 570 monozygotic twin pairs, 592 dizygotic twin pairs, and 426 non-twin siblings, aged 12-18 years, was recruited from the Colorado Twin Registry. For the past year data, there was a significant correlation between the genetic influences on MDD and CD and, for the lifetime data, there was a significant correlation between the genetic influences on MDD and CD, and a significant correlation between the nonshared environmental influences on MDD and CD. Our results suggest that some genetic factors will increase an individual's vulnerability to both MDD and CD in adolescence.

The effects of safety behaviors on the fear of contamination: an experimental investigation

The strategies used by anxious individuals to prevent feared outcomes, known as safety behaviors, are thought to maintain pathological anxiety by preventing the disconfirmation of inaccurate threat beliefs. However, it is possible that safety behaviors might also contribute to the development and exacerbation of anxiety symptoms. The present study tested this notion in a sample of undergraduate participants with either low (n=30) or high (n=26) levels of contamination fear. After a week-long baseline period, participants spent 1 week engaging in a clinically representative array of contamination-related safety behaviors on a daily basis, followed by a second baseline period. Subsequent to the safety behavior manipulation, participants evidenced statistically significant increases in threat overestimation, contamination fear symptoms, and emotional and avoidant responses to three contamination-related behavioral avoidance tasks (BATs). In contrast, anxiety and depressive symptoms remained stable. The magnitude of change in contamination concerns was equivalent among participants in both contamination fear groups. Our findings suggest that contamination-related safety behaviors elicit a modest and specific increase in the fear of contamination. Possible mechanisms for this effect, as well as implications for the role of safety behaviors in the psychopathology of anxiety disorders, are discussed.     

Reducing emergency medical service use in patients with chronic psychotic disorders: results from the FAST intervention study

Patients with schizophrenia have disproportionately high rates of emergency medical service use, likely contributing to the high cost this illness places on society. The aim of this study was to examine the impact of a theory-based, behavioral intervention on immediate and long-term use of emergency medical services. Older patients with schizophrenia (n=240) were randomized to receive either a behavioral, skills-building intervention known as Functional Adaptation and Skills Training (FAST) or a time-equivalent attention-control condition (AC). Logistic regression analyses indicated that AC participants were nearly twice as likely to use emergency medical services in general (OR=2.54; p=0.02) and emergency psychiatric services in particular (OR=3.69; p=0.05) during the active intervention phase of the study. However, there were no differences between the interventions in terms of emergency service use during the long-term follow-up phase of the study (i.e., 6-18 months post-baseline). The FAST intervention appears efficacious for reducing the short-term risk of using emergency medical services. However, the long-term efficacy of the FAST intervention appears less clear. Future studies may want to provide more powerful maintenance sessions to encourage continued use of skills in patients' real-world settings.     

Family burden of compulsive hoarding: results of an internet survey

Compulsive hoarding, the acquisition of and failure to discard large numbers of possessions, is associated with substantial health risk, impairment in functioning, and economic burden. Despite clear indications that hoarding has a detrimental effect on people living with or near someone with a hoarding problem, no empirical research has examined these harmful effects. The aim of the present study was to examine the burden of hoarding on family members. Six hundred sixty-five family informants who reported having a family member or friend with hoarding behaviors completed an internet-based survey. Living with an individual who hoards during childhood was associated with elevated reports of childhood distress and family strain. Family members reported high levels of patient rejection attitudes, suggesting high levels of family frustration and hostility. Rejecting attitudes were predicted by severity of hoarding symptoms, the individual's perceived lack of insight into the behavior, and having lived in a cluttered environment during childhood. These results suggest that compulsive hoarding adversely impacts not only the hoarding individual, but also those living with them.
