Pain-related anxiety and marijuana use motives: a pilot test among active marijuana-using young adults

The present investigation examined pain-related anxiety in regard to marijuana use motives among a sample of young adult marijuana users (N = 180; 45% women; M(age) = 21.11 years, SD = 6.41). Hierarchical multiple regression analyses were used to determine the relations between pain-related anxiety and marijuana use motives. After controlling for current marijuana use frequency (past 30 days), daily cigarette smoking rate, current rate of alcohol consumption, level of bodily pain (current), and other marijuana use motives, pain-related anxiety was significantly and uniquely associated with coping and conformity motives for marijuana use. Pain-related anxiety was not significantly related to other marijuana use motives. These results offer novel empirical insight pertaining to a relation between pain-related anxiety and coping as well as conformity motives for marijuana use among active users.

Development and evaluation of the evidence‐based practice classroom observation measure (EBP‐COM)

Due to the increased emphasis on evidence‐based practices (EBPs) in recent education initiatives, classroom observers need an objective way to measure teacher use of EBPs. Although some measures for this purpose exist, these measures are limited by their reliance on self‐report. Therefore, we created a direct observation tool titled the Evidence‐Based Practice Classroom Observation Measure (EBP‐COM) for observers to assess the use of EBPs by teachers of students with autism spectrum disorder (ASD). We evaluated reliability and validity of the EBP‐COM, as well as whether the assessment tool could detect change in teacher behavior. A measurement refinement process involving six raters collecting 65 data points revealed the EPB‐COM to have sound psychometric properties. With this tool, researchers can conduct comprehensive and objective assessments of teacher EBP use.     

The relationship between multidimensional economic well‐being and children’s mental health,physical health,and executive function development in South Africa

Conceptualizing both economic well‐being (EWB) and children's development as multidimensional constructs, the present study examines their association using bioecological developmental theory and structural equation modeling with Zulu children (ages 7–10) in KwaZulu‐Natal, a highly impoverished region of South Africa (N = 1,958). Relative EWB within impoverished communities consists of three dimensions: material assets (durable goods and living environment), fiscal appraisal (subjective experiences of access to/allocation of resources), and fiscal capacity (monetary inflow/outflow). Children's development also is measured across multiple dimensions: physical health, mental health, and executive functioning. In addition to an overall association between EWB and children's development across outcomes, the sub‐dimensions of EWB are differentially related to aspects of children's development. The dimension of material assets exhibits the greatest association with child outcomes, while fiscal capacity exhibits the least. Implications of these findings are discussed, including the use of multidimensional approaches to measuring EWB to understand, more clearly, its relationship to multiple dimensions of children's development.

Attachment styles,conflict styles and humour styles: interrelationships and associations with relationship satisfaction

Relationships among attachment styles, conflict styles and humour styles were examined in the context of romantic relationships. Each style was assumed to be based upon underlying assumptions about self and others, so relationships among the measures were predicted. A model assuming that the relationship of attachment styles to relationship satisfaction was partially mediated by the conflict styles and humour styles was tested. Overall, the predicted relationships among the three measures were supported. Conflict styles and humour styles reflecting attitudes about others were related to the avoidance attachment style, while those reflecting attitudes about the self were related to the anxiety attachment dimension. Conflict styles and humour styles were mediators of the association of attachment style with relationship satisfaction. Copyright © 2007 John Wiley & Sons, Ltd.     

Early individual differences in temperamental reactivity and regulation: implications for effortful control in early childhood

This longitudinal study tested the hypothesis that early temperament is associated with later effortful control. Fear reactivity and object orientation was assessed in a sample of 53 children at 8, 12, and 16 months during a stranger-approach paradigm and at 4.5 or 5.5 years on a battery of effortful control tasks. A latent growth curve analysis was used to model change in reactivity and object orientation across infancy and the prediction of each on later effortful control. Infants who increased in fear reactivity were significantly more likely to show poor performance on effortful control tasks in early childhood. Findings are discussed with respect to the importance of examining early temperamental precursors that contribute to the development of regulation.     

Trait impulsiveness and executive function in healthy young adults

Performance-based neuropsychological tests are often used to assess planning and impulse control, but the extent to which these measures reflect trait impulsiveness or specific dimensions of trait impulsiveness is not clear. This study used the Barratt Impulsiveness Scale-11 (BIS-11; [Patton, J. H., Stanford, M. S., & Barratt, E. S. (1995). Factor structure of the Barratt Impulsiveness Scale. Journal of Clinical Psychology, 51, 768–774.]) to examine the relationship between various dimensions of trait impulsiveness and performance on several executive function tests in healthy young adults. Total BIS-11 scores correlated with performance on measures of planning and impulse control. Higher non-planning impulsiveness scores, which indicate poorer self-control and lower cognitive complexity, correlated most strongly with performance on a maze test that measures planning and impulse control (r = .58). These results provide support for the convergent validity of pencil-and-paper maze-based measures of planning and impulse control.     

Arousal, working memory, and conscious awareness in contingency learning

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.     

Incest,Inbreeding, and Intrafamilial Conflict: Analyzing the Boundaries of Sexual Permissiveness in Modern North America

Our ability to critically analyze the effect of incestuous activity on society is complicated by the fact that such activity may take place in several different types of relationships, each of which play somewhat different roles within the family and community. Thus, if we are to analyze this effect in any meaningful manner, we must first take care to differentiate the various forms of incest from one another, and to study their consequences separately so that any effects due to relationship status, rather than to incest per se, can be taken into account. We must also ensure that we separate our definition of incest from that of non-consensual sex—that is, incest that occurs in couples in which one partner is too young to legally consent should be distinguished from incest that occurs between two consenting adults (i.e. incest per se), and the effects of these two variants of incest should as well be assessed separately. Using these careful definitions, it can be logically argued that incest on its own should not be prohibited in modern North American society, as the damage to our freedom that such a prohibition would entail cannot be justified by what little unambiguous evidence there is to support its case.
