Coping style and memory specificity in adolescents and adults with histories of child sexual abuse

Individuals with histories of childhood trauma may adopt a nonspecific memory retrieval strategy to avoid unpleasant and intrusive memories. In a sample of 93 adolescents and adults with or without histories of child sexual abuse (CSA), we tested the hypothesis that nonspecific memory retrieval is related to an individual's general tendency to use avoidant (i.e., distancing) coping as a personal problem-solving or coping strategy, especially in victims of CSA. We also examined age differences and other individual differences (e.g., trauma-related psychopathology) as predictors of nonspecific memories. Distancing coping was significantly associated with less specific autobiographical memory. Younger age, lower vocabulary scores, and non-CSA childhood maltreatment (i.e., physical and emotional abuse) also uniquely predicted less autobiographical memory specificity, whereas trauma-related psychopathology was associated with more specific memory. Implications for the development of autobiographical memory retrieval in the context of coping with childhood maltreatment are discussed.     

Minimal Risk of Internalizing Problems in Typically-Developing Siblings of Children with High-Functioning Autism Spectrum Disorder

We examined anxiety and depression clinical symptom levels in 42 typically-developing (TD) siblings of children with high-functioning autism spectrum disorder (HFASD), compared to 42 TD siblings of TD children, matched on age, ethnicity, and gender. Participants were between the ages of 6 and 16. Groups were compared using the parent-report and child self-report versions of the Behavior Assessment System for Children, Second Edition, anxiety and depression clinical scales. Within-group differences were examined for parent versus child ratings. Multivariate procedures did not support clinically elevated levels of internalizing problems in siblings of children with HFASD. Results from both sources were consistent with the overall finding. The findings do not support an increased need for targeted intervention, though clinical and school-based practitioners should attend to clinical warning signs if presented.     

An effectiveness trial of a new enhanced dissonance eating disorder prevention program among female college students

Objective

Efficacy trials indicate that a dissonance-based prevention program in which female high school and college students with body image concerns critique the thin-ideal reduced risk factors, eating disorder symptoms, and future eating disorder onset, but weaker effects emerged from an effectiveness trial wherein high school clinicians recruited students and delivered the program under real-world conditions. The present effectiveness trial tested whether a new enhanced dissonance version of this program produced larger effects when college clinicians recruited students and delivered the intervention using improved procedures to select, train, and supervise clinicians.

Method

Young women recruited from seven universities across the US (N = 408, M age = 21.6, SD = 5.64) were randomized to the dissonance intervention or an educational brochure control condition.

Results

Dissonance participants showed significantly greater decreases in risk factors (thin-ideal internalization, body dissatisfaction, dieting, negative affect) and eating disorder symptoms versus controls at posttest and 1-year follow-up, resulting in medium average effect size (d = .60). Dissonance participants also reported significant improvements in psychosocial functioning, but not reduced health care utilization or unhealthy weight gain.

Conclusions

This novel multisite effectiveness trial with college clinicians found that the enhanced dissonance version of this program and the improved facilitator selection/training procedures produced average effects that were 83% larger than effects observed in the high school effectiveness trial.     

Relation of depression to perceived social support: results from a randomized adolescent depression prevention trial

Theorists posit that certain behaviors exhibited by depressed individuals (e.g., negative self-statements, dependency, reassurance seeking, inappropriate or premature disclosures, passivity, social withdrawal) reduce social support, yet there have been few experimental tests of this hypothesis. Using data from a randomized depression prevention trial (N = 253) involving adolescents (M age = 15.5, SD = 1.2), we tested whether a cognitive behavioral group intervention that significantly reduced depressive symptoms relative to bibliotherapy and educational brochure control conditions through 2-year follow-up produced improvements in perceived parental and friend social support and whether change in depressive symptoms mediated the effect on change in social support. Cognitive behavioral group participants showed significantly greater increases in perceived friend social support through 1-year follow-up relative to bibliotherapy and brochure controls, but there were no significant effects for perceived parental support. Further, change in depressive symptoms appeared to mediate the effects of the intervention on change in perceived friend support. Results provide experimental support for the theory that depressive symptoms are inversely related to perceived social support, but imply that this effect may be specific to friend vs. parental support for adolescents.     

Comorbidity of unipolar depression: I. Major depression with dysthymia

The degree of current and lifetime comorbidity between major depressive disorder (MDD) and dysthymia (DY) was examined in large community samples of older adolescents (n = 1,710) and adults (n = 2,060). DY was highly comorbid with MDD (lifetime odds ratio of 3.4 for adolescents and 1.6 for adults) and was more likely to precede than to follow MDD, especially in persons who became depressed early in life. MDD was by far the more frequent form of depression: Approximately 80% of the depressed persons experienced only MDD, 10% experienced only DY, and 10% experienced both MDD and DY. The large number of persons who had became depressed twice experienced MDD in the 2nd episode, regardless of the nature of the 1st depression. History of depression was associated with a greater probability for other mental disorders in both adolescents and adults; however, the rates of comorbidity for MDD did not differ from rates for DY or for both MDD and DY.     

Markers of Topical Discourse in Child‐Directed Speech

Although the language we encounter is typically embedded in rich discourse contexts, many existing models of processing focus largely on phenomena that occur sentence‐internally. Similarly, most work on children's language learning does not consider how information can accumulate as a discourse progresses. Research in pragmatics, however, points to ways in which each subsequent utterance provides new opportunities for listeners to infer speaker meaning. Such inferences allow the listener to build up a representation of the speakers' intended topic and more generally to identify relationships, structures, and messages that extend across multiple utterances. We address this issue by analyzing a video corpus of child–caregiver interactions. We use topic continuity as an index of discourse structure, examining how caregivers introduce and discuss objects across utterances. For the analysis, utterances are grouped into topical discourse sequences using three annotation strategies: raw annotations of speakers' referents, the output of a model that groups utterances based on those annotations, and the judgments of human coders. We analyze how the lexical, syntactic, and social properties of caregiver–child interaction change over the course of a sequence of topically related utterances. Our findings suggest that many cues used to signal topicality in adult discourse are also available in child‐directed speech.     

Attention biases and habituation of attention biases are associated with 5-HTTLPR and COMTval158met

Fundamental biases in affective information processing are modulated by individual differences in the emotional response to environmental stimuli that may be partly based on the individual’s genetic make-up. To extend prior dot probe studies on attention genetics, we used a visual-search paradigm (VSP) with pictures of angry and happy faces of both sexes as targets, neutral faces as distractors, and a varying set size. Participants were selected a priori depending on their 5-HTTLPR (s/s, s/l, l/l; on a constant rs25531 A-allele background) and COMTval158met (val/val, valmet, met/met) genotypes and were matched for sex and age. We demonstrate a bias towards angry male faces (as opposed to happy male faces) irrespective of 5-HTTLPR genotype in the first experimental block that was maintained during the second experimental block only in carriers of the s-allele, which implies differential habituation processes. While a bias towards angry male faces was observed irrespective of COMTval158met genotype, only individuals with the val/val genotype exhibited a bias towards a happy female face (as opposed to an angry female face). In sum, our results both replicate and extend prior findings in the field of attention genetics and add important pieces of information to the research on attentional biases in emotion processing.     

Anxiety and Depression in Children with HFASDs: Symptom Levels and Source Differences

The purpose of this study was to: (1) examine symptom levels of anxiety and depression in children with high-functioning autism spectrum disorders (HFASDs) compared with matched control children using child self-reports and parent ratings; and (2) examine source differences within the two condition groups. An overall multivariate effect indicated significantly elevated depression and anxiety symptoms for children with HFASDs based on parent reports; however no significant between-group differences based on child self-reports. Within-condition source comparisons (parent vs. child) revealed a significant multivariate effect indicating a significant difference in symptoms of depression and anxiety for the HFASD group but none for the control. Correlations between parent and child reports for the HFASD group suggested some positive association between child-reports and parent-reports for depressive symptoms only; however, the difference in average scores reflected a substantial discrepancy in the magnitude of symptoms by rater. Implications for clinical assessment and future research are provided.
