Effectiveness of Dialectical Behavior Therapy for Treating Eating Disorders

This study evaluated the effectiveness of dialectical behavior therapy (DBT) for treating eating disorder episodes and co‐occurring depression symptoms among individuals diagnosed with eating disorders. Separate meta‐analytic procedures for between‐groups and single‐group studies were conducted and yielded large effect sizes, indicating that DBT may be efficacious for decreasing disordered episodes among women diagnosed with eating disorders; medium to large effect sizes were noted for treating depression symptoms. Implications for evidence‐supported practice and study limitations are discussed.     

Situational,Interpersonal, and Intrapersonal Characteristic Associations With Adolescent Conflict Forgiveness

Given the voluntary nature of adolescent friendships, forgiveness of interpersonal transgressions has been identified as a critical aspect of maintaining these relationships. However, transgression forgiveness is related to a range of situational (e.g., transgression severity), interpersonal (e.g., friendship commitment), and intrapersonal (e.g., victim's empathy) factors. Data from 161 adolescents were used to examine the nature of the relationships between these factors and forgiveness and to examine the differential association patterns for adolescent boys and girls. Results for the overall adolescent sample indicated both situational and interpersonal factor associations with forgiveness (R ² = .52, p < .001). Examination of separate female and male forgiveness reports indicated similar interpersonal factor associations and differential situational factor associations with female (R ² = .46, p < .001), and male (R ² = .60, p < .001) forgiveness. Findings suggest the likelihood of forgiving may be contextually dependent, and that researchers should consider transgression, relationship, and intrapersonal characteristics when examining forgiveness. Further, the present study suggests the contextual factors associated with forgiveness may be further differentiated by gender.     

Aging and the visual, haptic, and cross-modal perception of natural object shape

One hundred observers participated in two experiments designed to investigate aging and the perception of natural object shape. In the experiments, younger and older observers performed either a same/different shape discrimination task (experiment 1) or a cross-modal matching task (experiment 2). Quantitative effects of age were found in both experiments. The effect of age in experiment 1 was limited to cross-modal shape discrimination: there was no effect of age upon unimodal (ie within a single perceptual modality) shape discrimination. The effect of age in experiment 2 was eliminated when the older observers were either given an unlimited amount of time to perform the task or when the number of response alternatives was decreased. Overall, the results of the experiments reveal that older observers can effectively perceive 3-D shape from both vision and haptics.     

"Frog, where are you?" Narratives in children with specific language impairment, early focal brain injury, and Williams syndrome

In this cross-population study, we use narratives as a context to investigate language development in children from 4 to 12 years of age from three experimental groups: children with early unilateral focal brain damage (FL; N=52); children with specific language impairment (SLI; N=44); children with Williams syndrome (WMS; N=36), and typically developing controls. We compare the developmental trajectories of these groups in the following domains: morphological errors, use of complex syntax, complexity of narrative structure, and types and frequency of evaluative devices. For the children with early unilateral brain damage, there is initial delay. However, by age 10, they are generally within the normal range of performance for all narrative measures. Interestingly, there are few, if any, side specific differences. Children with SLI, who have no frank neurological damage and show no cognitive impairment demonstrate significantly more delay on all morphosyntactic measures than the FL group. Quantitatively, on morphosyntactic measures, the SLI group clusters with those children with WMS who are moderately retarded. Together these data help us to understand the extent and nature of brain plasticity for language development and those aspects of language and discourse that are dissociable.     

Brief assessment and treatment of pica using differential reinforcement,response interruption and redirection,and competing stimuli

Pica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non-edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies—namely, the augmented-CSA (A-CSA)—to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A-CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people.     

Promoting resilience to depression among couples during pregnancy: The protective functions of intimate relationship satisfaction and self-compassion

Pregnancy, while often marked by joy, may pose considerable risk for depression among parents. Against a backdrop of adverse life events, expectant parents may be even more vulnerable to developing symptoms of depression during the prenatal period. Thus, it is critical to identify sources of resilience that might facilitate a successful transition to parenthood among couples who have a history of adversity. Prior work suggests that interpersonal and intrapersonal factors associated with resilience, such as intimate relationship satisfaction and self-compassion (i.e., self-kindness, common humanity, and mindfulness), have the potential to attenuate prenatal depression among couples with a history of stressful life experiences. We tested this possibility in a sample of 159 couples navigating pregnancy. As predicted, a greater number of prior stressful life experiences was associated with increased depression symptom severity for both mothers and fathers. However, moderation analyses revealed the positive link between cumulative stressful life experiences and depression symptom severity was attenuated among mothers who reported greater self-compassion in the form of feelings of common humanity, and fathers who reported higher levels of intimate relationship satisfaction and self-compassion in the form of mindfulness. Findings suggest enhancing intimate relationship satisfaction and self-compassion among expectant couples may be valuable in attenuating prenatal depression among those with a greater history of adversity.     

Science Anxiety as a Function of Gender and Experience

This study examined the influence of gender and various background factors on science anxiety. Students (50 women, 37 men) took the Science Anxiety Scale (Mallow, 1994), provided information about high school and college academic accomplishments, described gender-role stereotyping in the home, and evaluated their science teachers and science experiences. Most participants were Caucasian and from an upper-middle class background. Women were not uniformly more science anxious and had a relatively similar science background to men, although they had higher science grades in high school and did report less stringent sex-role socialization in the home. However, students with high science anxiety took fewer science courses in college, had lower SAT-Q scores, and reported that their high school science teachers were not helpful. The findings regarding gender- and anxiety-linked differences are discussed in terms of women's and men's differential interpretations of their abilities, the influence of parental gender typing on pursuit of science, and the gender-appropriateness of studying science.

Observing mother-child relationships across generations: boundary patterns,attachment, and the transmission of caregiving

Grounded in both attachment and family systems theories, this study is one of the first to examine how relationship patterns observed in mothers' current relationships with their own mothers are recreated in their relationships with their infants. Mostly white, middle-class families (N = 55), including maternal grandmothers, mothers, and infants, were observed when infants were 6, 9, and 18 months old. At 6 months, mothers and grandmothers completed self-report assessments and worked together on discussion tasks. These interactions were coded using the Boundary Assessment Coding System, developed for the present study, which assessed three relational patterns: disengagement, balance, and entanglement. At 9 months, mothers were rated on sensitivity and intrusiveness while playing with and feeding their infants; and, at 18 months, infant-mother attachment was assessed using the Strange Situation. Multiple regression analyses revealed, as predicted, that mothers who remembered being accepted by their mothers as children and who were in highly balanced relationships with their own mothers currently were more sensitive and less intrusive with their 9-month-old infants. Further, discriminant function analyses indicated that memories of acceptance, high levels of balance, and low levels of disengagement differentiated secure from insecure attachment, whereas memories of overprotection and high levels of entanglement distinguished resistant from secure and avoidant attachment. Discussion focuses on the theoretical hypothesis that mothers internalize relationship strategies experienced with their own caregivers and recreate these patterns with their infants.     

The Effects of Tragedies and Contradictions on Religion as a Quest

The present study was designed to investigate the differential influences of exposure to life tragedies and religious contradictions on the tendency to engage in religious questioning (quest orientation). A replication and extension of a study by Burris, Jackson, Tarpley, and Smith (1996) was conducted to determine whether exposure to religious contradictions alone or life tragedies alone would influence quest orientation. Additional experimental conditions attempted to address Batson's (1982) theoretical position that quest orientation results “from a process of cognitive restructuring in response to existential questions” (p. 162). The results replicated Burris et al. (1996) and also showed that exposure to tragedy alone led to increases in quest orientation. The results did not support the idea that exposure to contradictions increased quest orientation. Unexpectedly, some evidence was found that exposure to tragedy influenced extrinsic orientation.
