Brief Counseling for Alcohol Misuse Among Trauma Patients: Two Interventions and Influence of Baseline Use

This study examined whether baseline trauma patient characteristics and randomized participation in 1 of 2 brief interventions predicted changes in alcohol use at 6 months postintervention. Higher total Alcohol Use Disorders Identification Test (AUDIT) scores predicted greater changes, and specific AUDIT items were significant predictors.     

Satisfaction and frustration of autonomy and relatedness needs: Associations with parenting dimensions and psychological functioning

Framed from Basic Psychological Needs Theory (Ryan and Deci in American Psychologist 55:68–78; Ryan, Deci, American Psychologist 55:68–78, 2000) and Ka?itçiba?i’s Autonomous-Related Self Theory (Journal of Cross-Cultural Psychology 36:1–20; Ka?itçiba?i, Journal of Cross-Cultural Psychology 36:1–20, 2005), the study examined the relationships of adolescents’ satisfaction and frustration of autonomy and relatedness, with (a) adolescents’ perception of mother’s and father’s psychological control and autonomy support, and (b) adolescents’ self-acceptance and anxiety. Participants were 556 adolescents (M?=?17.25, SD?=?0.92). Path analysis showed more significant associations of autonomy support with satisfaction/frustration of autonomy and relatedness than psychological control, reporting also some differences between parents. Moreover, both satisfaction and frustration of autonomy and relatedness were associated with adolescents’ self-acceptance and anxiety although in different ways. Our study provides further data, useful to understand how needs for autonomy and relatedness are associated with parenting dimensions and contribute to the adjustment of adolescents living in psychologically interdependent cultures, taking into account the role of each parent as well as the separate contribution of need satisfaction and need frustration.     

Development switch in neural circuitry underlying odor-malaise learning

Fetal and infant rats can learn to avoid odors paired with illness before development of brain areas supporting this learning in adults, suggesting an alternate learning circuit. Here we begin to document the transition from the infant to adult neural circuit underlying odor-malaise avoidance learning using LiCl (0.3 M; 1% of body weight, ip) and a 30-min peppermint-odor exposure. Conditioning groups included: Paired odor-LiCl, Paired odor-LiCl-Nursing, LiCl, and odor-saline. Results showed that Paired LiCl-odor conditioning induced a learned odor aversion in postnatal day (PN) 7, 12, and 23 pups. Odor-LiCl Paired Nursing induced a learned odor preference in PN7 and PN12 pups but blocked learning in PN23 pups. 14C 2-deoxyglucose (2-DG) autoradiography indicated enhanced olfactory bulb activity in PN7 and PN12 pups with odor preference and avoidance learning. The odor aversion in weanling aged (PN23) pups resulted in enhanced amygdala activity in Paired odor-LiCl pups, but not if they were nursing. Thus, the neural circuit supporting malaise-induced aversions changes over development, indicating that similar infant and adult-learned behaviors may have distinct neural circuits.     

COMT genotype influences prefrontal response to emotional distraction

Early studies of genetic effects on brain activity have been conducted to investigate primarily either the influence of polymorphisms in dopaminergic genes, especially the catechol-O-methyltransferase (COMT) gene, on prefrontal cognitive processes such as working memory, or that of polymorphisms in the serotonin transporter gene on the amygdala response to threatening stimuli. Here, we address genetic influences on the neural systems underlying cognitive-affective interactions. Specifically, we assess the effect of the COMT val¹⁵⁸met polymorphism on frontal regulation of attention under emotional distraction. Healthy volunteers were scanned while performing a house-matching task with affectively negative versus neutral distractors. Effects of val allele load were examined on frontal regions associated with attentional control and emotion regulation, and on parahippocampal regions associated with perception of houses. As we predicted, val load correlated positively with activity in control- and task-related regions during performance under emotional distraction. These findings provide an initial step toward identifying genetic contributions to interindividual variability in recruitment of mechanisms that regulate affective processing.     

Gender differences in victimized homeless adolescents

Most of what we know about sexual abuse comes from efforts to examine female children victimized by men. Although some researchers have identified similarities between male and female victims of sexual abuse, few studies have examined gender-specific factors associated with sexual health practices among homeless adolescents. The aim of this study was to explore how gender and history of sexual abuse influence cognitive-perceptual and behavioral factors associated with sexual health practices of homeless adolescents. This study was a secondary analysis of data collected for a cross-sectional study of the sexual health practices of homeless adolescents. The sample consisted of 414 youths (104 males who reported sexual abuse and 124 who did not; and 95 females who reported sexual abuse and 75 who did not; 16 did not provide these data). Homeless adolescent females with a history of sexual abuse scored higher (indicating a shorter perspective) on a measure of future time perspective than females with no sexual abuse. Males who reported no sexual abuse scored higher than abused females on perceived health status and higher than abused males on assertive communication. With respect to perceived health status, males who reported no sexual abuse scored significantly higher than females who reported sexual abuse (p = .04). Males with no sexual abuse had significantly higher assertive communication scores than did males who had experienced sexual abuse (p = .015). We found that male and female abuse victims differ in terms of their cognitive-perceptual and behavioral factors associated with sexual health practices. Early identification of those who have been abused is critical so that interventions can be developed. Effective short-term interventions are needed for the adolescent victims of Child Sexual Abuse (CSA), particularly those who are homeless and prone to further sexual victimization.     

Syllables as processing units in handwriting production

This research focused on the syllable as a processing unit in handwriting. Participants wrote, in uppercase letters, words that had been visually presented. The interletter intervals provide information on the timing of motor production. In Experiment 1, French participants wrote words that shared the initial letters but had different syllable boundaries. In Experiment 2, French- and Spanish-speaking participants wrote cognates and pseudowords with a letter sequence that was always intrasyllabic in French and intersyllabic in Spanish. In Experiment 3, French-Spanish bilinguals wrote the cognates and pseudowords with the same type of sequences. In the 3 experiments, the critical interletter intervals were longer between syllables than within syllables, indicating that word syllable structure constrains motor production both in French and Spanish.     

Adoption and maintenance of physical activity: Planning interventions in young, middle-aged, and older adults

Young, middle-aged, and older adults in orthopaedic outpatient rehabilitation (N?=?373) were randomly assigned to either an interviewer-assisted or a standard-care self-administered planning intervention. Physical activity planning consisted of specifying action plans to facilitate action initiation, and coping plans to overcome barriers. The interviewer-assisted condition led to more complete action plans and a longer duration of physical activities up to six months after discharge. Regarding coping planning, older and middle-aged adults benefited more from interviewer-assisted planning while younger adults benefited more from self-administered planning. Planning as such was found to be an effective tool for enactment irrespective of chronological age. The delayed effect of coping planning on enactment suggests that coping planning is important for long-term maintenance.     

Examination stress as an ecological inducer of cortisol and psychological responses to stress in undergraduate students

The purpose of the present study was to investigate basic methodological issues related to the usage of an examination stress protocol in studies of psychoneuroendocrinology. In the present study, 57 undergraduate students served as participants. All subjects provided salivary samples and completed psychological inventories during a low examination stress period and again during a high examination stress period. Salivary samples were analyzed for cortisol. Three major findings were observed. First, the examination stress protocol proved to be an effective trigger of elevations in both psychological measures of stress and in cortisol levels. Second, sex differences were observed in cortisol levels, such that males showed an elevation in cortisol during the high examination stress session whereas females did not. Finally, no significant correlations were observed between elevations in psychological measures of stress and elevations in cortisol levels. These findings suggest that the examination stress protocol used in the present study effectively elevated both psychological stress and cortisol levels. Furthermore, these findings suggest that there are biological differences in how males and females respond to stress. Finally, no evidence was found to suggest a relationship between psychological and hormonal levels of stress. Together, these findings suggest the need to better define and consider the implications of both the specific measures of stress being used and individual differences in the subject samples in psychoendocrine studies.
