Negative Affect Shares Genetic and Environmental Influences with Symptoms of Childhood Internalizing and Externalizing Disorders

The co-occurrence of internalizing and externalizing disorders suggests that they may have common underlying vulnerability factors. Research has shown that negative affect is moderately positively correlated with both internalizing and externalizing disorders in children. The present study is the first to provide an examination of negative affect in relation to a wide spectrum of childhood internalizing and externalizing problems using a biometric model. This study extends prior findings of more narrowly focused associations by using a factor approach including multiple disorders. The sample for this study included families of 691 same-sex 7- to 13-year old twin pairs. A multifactorial independent pathway model was used to examine the genetic and environmental influences underlying the covariation of parent-reported negative affect, internalizing symptoms, and externalizing symptoms. Results of the current study suggest that negative affect shares genetic and environmental influences with both internalizing and externalizing disorders in childhood. These common influences may partially explain their comorbidity. Understanding that negative affect is at least one contributor to the covariation among these disorders may highlight avenues for early risk assessment, intervention, and perhaps prevention.     

Acceptance and Commitment Therapy for Eating Disorders: Rationale and Literature Review

Empirical studies using Acceptance and commitment therapy (ACT) and its components to treat eating disorders (EDs) were reviewed. Evidence suggests that emotional avoidance is a major component in the onset and maintenance of EDs. Acceptance and commitment therapy targets emotional avoidance and control strategies with six core processes. These core processes have been applied to EDs and demonstrated improvement in subjects’ functioning and reduction in disordered eating. There are several advantages of using ACT for treating EDs: ACT fundamentally equalizes the therapeutic relationship; experiential techniques in ACT may facilitate lasting treatment gains; ACT navigates the ego-syntonic nature of EDs; the ACT conceptualization based on experiential avoidance and cognitive rigidity in EDs is consistent with current literature. The six core processes of ACT can be further modified to fit the challenges of treating EDs. Specifically, concerns about client motivation for treatment can be addressed by emphasizing creative hopelessness and a values construction process earlier in treatment.     

Examination of Life Satisfaction,Child Maltreatment Potential and Substance Use in Mothers Referred for Treatment by Child Protective Services for Child Neglect and Substance Abuse: Implications for Intervention Planning

There is evidence to suggest mothers who are served by child protective service agencies are relatively dissatisfied in their lives, leading some investigators to conclude life dissatisfaction may be associated with child maltreatment. To assist in better understanding this relationship the Life Satisfaction Scale for Caregivers (LSSC) was psychometrically developed in a sample of 72 mothers who were referred for behavioral treatment for child neglect and substance abuse by caseworkers from a local child protective service agency. The LSSC was developed to assess mothers’ happiness in nine domains (family, friendships, employment/work, spirituality/religion, safety, sex life/dating, ability to avoid drugs, ability to avoid alcohol, control over one’s own life). Results indicated two factors that appeared to be relevant to Social Satisfaction and Safety and Control Satisfaction. Higher satisfaction scores on both of these scales were negatively associated with child maltreatment potential and substance use at baseline (i.e., positive urinalysis test). Mothers who exposed their children to substances in utero or in infancy (a distinct type of child neglect) were found to report higher satisfaction scores on the LSSC than other types of child neglect. Hispanic-American, African-American, and Caucasian women reported similar levels of life satisfaction. Application of the LSSC as a non-stigmatizing, wellness-focused instrument is discussed within the context of intervention planning.     

Social support,psychological vulnerability,and HIV risk among African American men who have sex with men

Previous research has suggested a need to understand the social-psychological factors contributing to HIV risk among African American men who have sex with men (MSM). We conducted individual in-depth interviews with 34 adult African American MSM to examine their personal experiences about: (i) sources of social support, (ii) psychological responses to the presence or absence of social support and (iii) influences of social support on sexual behaviours. The majority of participants described limited positive encouragement and lack of emotional support from family, as well as few meaningful personal relationships. Feelings of isolation and mistrust about personal relationships led many participants to avoid emotional intimacy and seek physical intimacy through sexual encounters. Findings highlight a need for multilevel interventions that enhance social support networks and address the social-psychological, emotional and interpersonal factors that contribute to HIV risk among African American MSM.     

Cognitive vulnerability to depression: a taxometric analysis

Although there is increasing support for the hypothesis that negative cognitive styles contribute vulnerability to depression, it remains unclear how best to conceptualize the heterogeneity in cognitive vulnerability to depression. Specifically, does this heterogeneity reflect quantitative or qualitative differences among individuals? The goal of this study was to address this question by examining whether the underlying structure of cognitive vulnerability to depression is best conceptualized as dimensional or categorical. Taxometric analyses provided consistent support for the dimensional nature of negative cognitive styles. It appears, therefore, that cognitive vulnerability to depression is best conceptualized as a dimensional construct, present to a greater or lesser extent in all individuals. Despite this, the strength of the relationship between negative cognitive styles and depressive symptoms does appear to vary as a function of where along the cognitive style continuum one falls.     

The time course of perception and retrieval in matching and recognition

A four-part experiment was carried out to study the relationship between the time course of object-feature perception and the time course of retrieval of object information from memory. The experiment consisted of 2 perceptual matching tasks, and 2 perceptual recognition tasks. In all 4 tasks, participants provided speeded judgments of the identity of 2 objects. A stochastic feature-sampling model was used to estimate the time needed for feature perception and the time needed for retrieval of feature information. No evidence was found for a systematic relationship between perception times and retrieval times for individual features. Indeed, the model applications indicated that retrieval times were constant for different features, whereas perception rates varied across the features.     

Trait and social processes in the link between social support and affect: an experimental, laboratory investigation

This study investigated the extent to which the link between perceived social support and affect reflected support recipients' trait perceived support as well as three distinct social processes: the objective supportiveness of providers, the unique relationships among recipients and providers that were stable over occasions, as well as the unique relationships that varied across occasions. Ten recipients interacted with each of the same four providers on five separate occasions, for a total of 200 interactions. Recipients and independent observers rated recipient affect and provider support. Greater perceived support was related to greater positive affect for recipients' trait perceived support, as well as for relationships that were stable over occasions and relationships that varied across occasions. No social support effects were found for negative affect. Perceived similarity was a consistent predictor of recipients' support perceptions. Implications for social support models and interventions were discussed.     

CONSERVATIVE IDEOLOGY AND AMBIVALENT SEXISM

To assess the relationship between different facets of conservative ideology and ambivalent sexism, 246 residents of two towns in southern Michigan completed a social dominance orientation scale (SDO), a right-wing authoritarianism scale (RWA), a Protestant work ethic scale (PWE), and the Glick and Fiske (1996) Ambivalent Sexism Inventory via a mail survey. Zero-order correlations revealed that SDO, RWA, and PWE were each related to both components of ambivalent sexism (hostile and benevolent sexism). Hierarchical regressions revealed that SDO and PWE most strongly predicted hostile sexism, whereas RWA most strongly predicted benevolent sexism. Results are discussed with respect to different facets of conservative ideology and why SDO, RWA, and PWE each tend to be associated with prejudice toward different groups.     

SCiP at 35: An idiosyncratic history of the Society for Computers in Psychology

SCiP history may be divided into three eras: the Paleozoic (1971–1982), the Mesozoic (1982–1994), and the Cenozoic (1994-present). Following a list of Secretary-Treasurers, a list of all SCiP Presidents is provided in Table 1. Next I present personal highlights, including the first symposium on psychology and the World-Wide Web; David Rumelhart’s mathematical explanation of connectionism; and Stevan Harnad’s discussion of “freeing” the journal literature. I observe that a small conference is becoming more intimate and that much of our mission involves figuring out how to conduct high-quality scientific research with consumer-grade electronics. I argue that we are an increasingly international organization, that graduate students are welcome, and that we should become more inclusive in the areas of gender and ethnicity and should make membership more meaningful. I conclude by looking ahead and attempting to predict the future.
