Habituation or Normalization? Experiential and Respiratory Recovery From Voluntary Hyperventilation in Treated Versus Untreated Patients With Panic Disorder

Psychophysiological theories postulate respiratory dysregulation as a mechanism contributing to panic disorder (PD). Additionally, symptomatic and respiratory recovery from voluntary hyperventilation (HVT-recovery) have been shown to lag in PD and it is unclear if HVT-recovery normalizes with treatment. Thirty-seven panic disorder patients were randomized to hypoventilation therapy (TX, n = 20) or waitlist control (WL, n = 17) (Meuret et al., 2008). In a secondary analysis, their HVT-recovery was analyzed at pre- and post-TX/WL, compared to 29 healthy controls (HC). HVT included three phases: 5-min baseline, 3-min hyperventilation, and 8-min recovery. HVT-elicited symptom severity and anxiety were rated following each phase, and end-tidal PCO₂ and respiratory rate (RR) were recorded throughout. Treatment, compared to WL, was highly effective in reducing PD pathology (d = 2.21, Meuret et al., 2008). At pre-TX/WL, PD demonstrated delayed HVT-recovery PCO₂ and higher RR. Treated patients demonstrated normalization of HVT-recovery for PCO₂ and RR; however, improvements of HVT-recovery for symptom severity and anxiety did not differ between TX and WL. Results replicate pretreatment HVT respiratory recovery abnormalities in PD and further demonstrate normalization, comparable to HC, following successful treatment. The results provide support for respiratory dysregulation as a feature of PD and demonstrate the utility of HVT respiratory recovery as treatment outcome measure for respiration-based PD therapy.     

Pilot Trial of Acceptance-Based Behavioral Weight Loss and Neurocognition Among American Indians

Acceptance-based behavioral therapies (ABTs) for obesity may be superior to standard behavioral therapies but have not been adequately tested with American Indians (AIs). Neurocognitive function is also unexamined in relation to behavioral weight loss among AIs despite findings that neurocognition predicts outcomes in general samples, may help explain some of the benefits of ABTs, and may be relevant to marginalized groups. The primary objective of this pilot was to examine the feasibility/acceptability of ABT in an AI sample. Exploratory analyses examined the relationship between neurocognition and weight loss. Forty-eight AI adults with overweight/obesity (ages 43.3 ± 10.3 years, 85% female; baseline body mass index = 36.8 ± 4.4 kg/m²) enrolled in a 6-month open ABT weight loss trial. Feasibility indices, including screening/enrollment, session attendance, retention rates for posttreatment assessments, and program acceptability were examined. Percent weight loss (%WL) was assessed as well as fluid and crystalized neurocognition (National Institutes of Health Toolbox Cognition Battery [NIHTB-CB]). We enrolled 79% of the eligible sample and retained 75% (N = 36) at posttreatment assessments. Program completers lost an average of 5.2 ± 4.9% of initial body weight (d_z = 1.14), whereas intent-to-treat analyses show a mean loss of 4.1 ± 4.7%. Participants reported high satisfaction, effectiveness, and cultural appropriateness. Exploratory analyses of neurocognitive domains suggested that crystalized cognition was higher among completers, and higher baseline cognitive flexibility predicted greater %WL (β = .34, p = .05). ABT resulted in clinically significant weight loss in an AI sample. A controlled trial of ABT in a larger, more diverse sample is warranted to determine whether (a) the findings are robust, generalizable, and/or superior to other treatments and (b) neurocognitive factors moderate outcomes.     

Birthweight predicts individual differences in adult face recognition ability

It has long been known that premature birth and/or low birthweight can lead to general difficulties in cognitive and emotional functioning throughout childhood. However, the influence of these factors on more specific processes has seldom been addressed, despite their potential to account for wide individual differences in performance that often appear innate. Here, we examined the influence of gestation and birthweight on adults’ face perception and face memory skills. Performance on both sub-processes was predicted by birthweight and birthweight-for-gestation, but not gestation alone. Evidence was also found for the domain-specificity of these effects: No perinatal measure correlated with performance on object perception or memory tasks, but they were related to the size of the face inversion effect on the perceptual test. This evidence indicates a novel, very early influence on individual differences in face recognition ability, which persists into adulthood, influences face-processing strategy itself, and may be domain-specific.     

Antisocial Process Screening Device Subscales Predict Recidivism in an Australian Juvenile Offender Sample

The present study is the first to examine the psychometric properties of the self-report Antisocial Process Screening Device (APSD-SR), and the predictive utility of its subscales for reoffending, among Australian juvenile offenders (N?= 308, M age = 17.00, SD?=?1.49). Exploratory factor analysis supported a modified three-factor structure in which four items loaded differently to prior studies. Total APSD-SR and modified subscale scores were positively associated with criminal history and mental health problems (e.g., internalizing and externalizing problems, alcohol and substance abuse/dependence). Survival analyses indicated that youth scoring high on the APSD-SR total score were faster to reoffend nonviolently (Hazard Ratio [HR]?= 1.31, p?=?.0003) and violently (HR?=?1.42, p?=?.0003) than those scoring low. Whereas the modified grandiose-manipulative subscale predicted faster time to nonviolent recidivism (HR?=?1.18, p?=?.026) as a single predictor, when all subscales were simultaneously entered into the model only callous-unemotional (CU) traits and impulsivity predicted nonviolent recidivism (HR?=?1.19, p?=?.026 and 1.22, p?=?.015, respectively), and only impulsivity predicted violent recidivism (HR?=?1.26, p?=?.014). Findings inform current understanding of the relative contribution of adolescent psychopathy dimensions to designating a particularly high-risk group of Australian youth in custody.

Analysis of self-recording in self-management interventions for stereotypy

Most treatments for stereotypy involve arrangements of antecedent or consequent events that are imposed entirely by a therapist. By contrast, results of some studies suggest that self-recording, a common component of self-management interventions, might be an effective and efficient way to reduce stereotypy. Because the procedure typically has included instructions to refrain from stereotypy, self-recording of the absence of stereotypy, and differential reinforcement of accurate recording, it is unclear which element or combination of elements produces reductions in stereotypy. We conducted a component analysis of a self-management intervention and observed that decreases in stereotypy might be attributable to instructional control or to differential reinforcement, but that self-recording per se had little effect on stereotypy.     

Relationships among self-esteem, stress, and physical activity in college students

The purpose of this study was to identify population and sex-specific relationships between perceived stress, self-esteem, and physical activity in college students. 90 students, ages 18 and older and enrolled in five sections of a health and human behavior class during the spring 2010 semester, were contacted for this study with 74 consenting to serve as study participants. Each participant completed three surveys: the Rosenberg Self-Esteem Scale, the Perceived Stress Scale, and the International Physical Activity Questionnaire. Significant correlations were observed between perceived stress and self-esteem in men, and in women. Physical activity was not significantly correlated with perceived stress or self-esteem.
