Aversive smoking therapies: A conditioning analysis of therapeutic effectiveness

Rapid smoking (RS) and a less aversive rapid-puffing (RP) treatment were compared on ability to enhance the impact of a behavioral-counseling (BC) procedure on psychophysiological, attitudinal and behavioral response to cigarettes. Data reveal that both aversive smoking treatments resulted in less smoking once treatment began, reduced smoking in post-treatment taste tests, and superior follow-up performance at 6 months and 1 yr. At 1 yr, RS S s achieved the highest number of days abstinent of any group. Regression analyses showed that Ss' confidence ratings of remaining abstinent were highly predictive of follow-up status, and that these ratings were related to number of cigarettes smoked during treatment and amount of smoking during post-treatment taste tests.     

Reward value effects on timing in the peak procedure

Three experiments examined the effect of motivational variables on timing in the peak procedure. In Experiment 1, rats received a 60-s peak procedure that was coupled with long-term, between-phase changes in reinforcer magnitude. Increases in reinforcer magnitude produced a leftward shift in the peak that persisted for 20 sessions of training. In a final phase, the rats received lithium chloride-induced aversion prior to testing and a rightward shift in the peak was observed. Experiment 2 confirmed the rightward shift in the peak under lithium chloride devaluation and induced a comparable shift with satiety devaluation. The degree of rightward shift was neither additive nor multiplicative, suggesting that two processes may have contributed. Experiment 3 examined the effect of extinction on peak responding, revealing a decrease in response rate, but no evidence of any change in the timing of responding. The implications of the results for contemporary timing theories are discussed.     

Intolerance of Uncertainty and Eating Disorder Symptoms Over the Course of Intensive Treatment

There is a critical need to identify processes that may influence outcome in existing treatments for eating disorders (EDs). Intolerance of uncertainty (IU), which refers to excessive distress regarding uncertain situations, is a well-established feature of anxiety disorders. Emerging work suggests that IU decreases over the course of cognitive-behavioral treatments and may relate to better treatment outcomes. As some literature has suggested IU may functionally maintain ED symptoms, testing whether changes in IU over treatment relate to outcome may result in the identification of novel treatment targets. This study aimed to build upon past work documenting links between IU and ED symptoms by exploring changes in IU over treatment and links between early change in IU (1-month) and discharge symptoms. Participants (N = 274) receiving partial hospitalization treatment completed the Eating Pathology Symptoms Inventory and Intolerance of Uncertainty Scale at admission, 1-month post-admission, and discharge. Results suggested that IU significantly reduced from admission to discharge and that reductions in IU scores from admission to 1-month related to cognitive restraint, dietary restriction, and body image at discharge. However, this pattern did not hold for exercise, binge eating, or purging. Altogether, these results replicate past work supporting IU as a common feature across ED diagnoses and provide initial data suggesting that targeting IU early in treatment may enhance treatment outcomes.     

Developmental effects of an intervention for preterm infants of teenage mothers

Since preterm infants and infants born to teenage mothers are noted to be at risk for developmental delays, a group of infants who were both preterm and born to teenage mothers was provided a sensorimotor exercise intervention program for the first year of infancy. The development of these infants was compared to the development of preterm infants without intervention and term infants of teenage mothers as well as term and preterm infants of adult mothers to determine the degree to which developmental delays were prevented. The intervention infants showed more optimal growth, cognitive development, temperament and play behaviors during interactions with their mothers across the first year of development.     

Prenatal depression effects on the fetus and newborn: a review

A review of research on prenatal depression effects on the fetus and newborn suggests that they experience prenatal, perinatal and postnatal complications. Fetal activity is elevated, prenatal growth is delayed, and prematurity and low birthweight occur more often. Newborns of depressed mothers then show a biochemical/physiological profile that mimics their mothers' prenatal biochemical/physiological profile including elevated cortisol, lower levels of dopamine and serotonin, greater relative right frontal EEG activation and lower vagal tone. Elevated prenatal maternal cortisol is the strongest predictor of these neonatal outcomes. Moderate pressure massage can alleviate these effects including reducing prematurity.     

Changes in Reporting of Suicide News After the Promotion of the WHO Media Recommendations

Media recommendations on suicide reporting are available in many countries and in different languages. Hong Kong newspapers have been found to be noncompliant with WHO recommendations. A booklet containing WHO media guidelines Preventing Suicide: A Resource for Media Professionals, and an awareness campaign were launched in November 2004 in Hong Kong. Content analysis was then conducted to compare the reporting of suicide news before and after the launch. Results indicate that certain reporting styles were changed in accordance with the recommendations; namely, lessened use of pictorial presentations and headlines mentioning suicides. Most of the changes were attributed to the tabloid‐style newspapers. This study suggests that programs to promote media recommendations tailored for journalists appear to be efficacious in altering their way of reporting.
