Serotonin Transporter Genotype Moderates the Link Between Children’s Reports of Overprotective Parenting and Their Behavioral Inhibition

The goal of the current study was to examine environmental and genetic correlates of children’s levels of behavioral inhibition (BI). Participants were 100 mother child pairs drawn from the community who were part of a larger study of the intergenerational transmission of depression. Results indicated that higher levels of maternal overprotection, as reported by the child, were associated with elevations in BI among children carrying two copies of the lower expressing 5-HTTLPR alleles (S or L_G), but not among those carrying only one copy or those homozygous for the L_A allele. In addition, this interaction was specific for the social component of BI, not the nonsocial component. This relation was maintained even after statistically controlling for children’s and mother’s psychopathology. Together, these findings add to emerging research demonstrating that G × E interactions predict variation in BI during childhood.     

Children's 5-HTTLPR genotype moderates the link between maternal criticism and attentional biases specifically for facial displays of anger

Theorists have proposed that negative experiences in childhood may contribute to the development of experience-specific information-processing biases, including attentional biases. There are also clear genetic influences on cognitive processes, with evidence that polymorphisms in specific candidate genes may moderate the impact of environmental stress on attentional biases (e.g., a functional polymorphism in the serotonin transporter gene; 5-HTTLPR). In the current study, we tested a gene×environment (G×E) model of risk for attentional biases. We hypothesised that children whose mothers exhibit high levels of expressed emotion criticism (EE-Crit) would display attentional biases specifically for angry, but not happy or sad, faces, and that this link would be stronger among children carrying one or two copies of the 5-HTTLPR short allele than among those homozygous for the long allele. Results generally supported these hypotheses, though we found that carriers of the 5-HTTLPR short allele who also had a critical mother exhibited attentional avoidance of angry faces rather than preferential attention.     

Social Dominance Orientation Relates to Believing Men Should Dominate Sexually, Sexual Self-Efficacy, and Taking Free Female Condoms Among Undergraduate Women and Men

Gendered-based power affects heterosexual relationships, with beliefs in the U.S. prescribing that men dominate women sexually. We draw on social dominance theory to examine whether women??s and men??s level of support for group-based hierarchy (i.e., social dominance orientation; SDO) helps explain gender-based power beliefs and dynamics in heterosexual relationships. We conducted a laboratory study at a Northeastern U.S. university among 357 women and 126 men undergraduates who reported being heterosexual and sexually active, testing three sets of hypotheses. First, as hypothesized, women endorsed SDO and the belief that men should dominate sexually less than men did. Second, as hypothesized, among women and men, SDO was positively correlated with the belief that men should dominate sexually, and negatively correlated with sexual self-efficacy (confidence in sexual situations) and number of female condoms (a woman-controlled source of protection) taken. Third, structural equation modeling, controlling for age, family income, number of sexual partners in the past month, and perceived HIV/AIDS risk, supported the hypothesis that among women and men, the belief that men should dominate sexually mediates SDO??s association with sexual self-efficacy. The hypothesis that the belief that men should dominate sexually mediates SDO??s association with number of female condoms taken was supported for women only. The hypothesis that sexual self-efficacy mediates SDO??s association with number of female condoms taken was not supported. Results suggest SDO influences power beliefs and dynamics in heterosexual relationships. Although female condoms are an important woman-controlled source of protection, power-related beliefs may pose a challenge to their use.     

Meta-Analysis of Single-Case Design Research on Self-Regulatory Interventions for Academic Performance

The current study examined the effects of self-regulatory interventions on reading, writing, and math by conducting a meta-analysis of single-case design research. Self-regulatory interventions have promise as an effective approach that is both minimally invasive and involves minimal resources. Effects of the interventions were analyzed by academic subject, grade, educational placement, and the number of sessions. Results indicated that self-regulatory strategies showed promise in addressing academic issues in the areas of reading, writing, and math regardless of age, grade, educational placement, and intervention length.     

Investigating the interaction between schizotypy, divergent thinking and cannabis use

Cannabis acutely increases schizotypy and chronic use is associated with elevated rates of psychosis. Creative individuals have higher levels of schizotypy, however links between cannabis use, schizotypy and creativity have not been investigated. We investigated the effects of cannabis smoked naturalistically on schizotypy and divergent thinking, a measure of creativity. One hundred and sixty cannabis users were tested on 1 day when sober and another day when intoxicated with cannabis. State and trait measures of both schizotypy and creativity were administered. Quartile splits compared those lowest (n=47) and highest (n=43) in trait creativity. Cannabis increased verbal fluency in low creatives to the same level as that of high creatives. Cannabis increased state psychosis-like symptoms in both groups and the high creativity group were significantly higher in trait schizotypy, but this does not appear to be linked to the verbal fluency change. Acute cannabis use increases divergent thinking as indexed by verbal fluency in low creatives.     

Transtheoretical Model Constructs for Physical Activity Behavior are Invariant across Time among Ethnically Diverse Adults in Hawaii

OBJECTIVES: Physical activity (PA) research applying the Transtheoretical Model (TTM) to examine group differences and/or change over time requires preliminary evidence of factorial validity and invariance. The current study examined the factorial validity and longitudinal invariance of TTM constructs recently revised for PA. METHOD: Participants from an ethnically diverse sample in Hawaii (N=700) completed questionnaires capturing each TTM construct. RESULTS: Factorial validity was confirmed for each construct using confirmatory factor analysis with full-information maximum likelihood. Longitudinal invariance was evidenced across a shorter (3-month) and longer (6-month) time period via nested model comparisons. CONCLUSIONS: The questionnaires for each validated TTM construct are provided, and can now be generalized across similar subgroups and time points. Further validation of the provided measures is suggested in additional populations and across extended time points.     

Parent Motivation to Participate in Treatment: Assessment and Prediction of Subsequent Participation

Treatment motivation is required for virtually all psychosocial treatments because clients must participate actively in the treatment process. In child and family treatments, it is the parent who must be motivated to manage treatment participation; however, no measures are currently available for evaluating parent motivation for treatment. The authors developed and evaluated a brief rating scale, the Parent Motivation Inventory (PMI), to measure parent motivation to participate in treatment. Results supported a uni-dimensional measure with strong internal consistency and test-retest reliability. Increases in parent motivation predicted the perception of fewer barriers to treatment participation, which was significantly associated with greater treatment attendance. The PMI provides a reliable and valid method of assessing parents’ motivation to participate in treatment and has implications for the prediction and potential modification of barriers to treatment and treatment participation.     

Treatment of co-occurring child maltreatment and substance abuse

Despite high prevalence and severe negative consequences of child maltreatment (e.g., Brown, G. R., & Anderson, B., (1991). Psychiatric morbidity in adult inpatients with childhood histories of sexual and physical abuse. American Journal of Psychiatry, 148, 55–61; Jaudes, P. K., Ekwo, E., & Van Voorhis, J.V., (1995). Association of drug abuse and child abuse. Child Abuse and Neglect, 19, 1065–1075; Murphy, J. M., Jellinek, M., Quinn, D., Smith, G., & Goshkom, M., (1991). Substance abuse and serious child mistreatment: Prevalence, risk, and outcome in a court sample. Child Abuse and Neglect, 15, 197—211), the treatment of perpetrators and victims of child abuse and neglect remains grossly understudied (Behl, L. E., Conyngham, H. A., & May, P. F., (2003). Trends in child maltreatment literature. Child Abuse and Neglect, 27, 215–229). More than half of parentes founded for the abuse and neglect of their children have evidenced drug abuse, yet no treatments have been validated that concurrently address these problems. The reciprocal interaction between substance abuse and child maltreatment supports the need to concurrently treat these problems. This article illustrates the relationship between child maltreatment and parental substance abuse and proposes a behavioral model to explain the reciprocal influence of drug abuse and child maltreatment. A behavioral treatment plan that is designed to concurrently address drug abuse and child abuse is proposed and suggestions are made for future directions in this area.
