The relation between smoking-specific parenting and smoking trajectories of adolescents: How are changes in parenting related to changes in smoking?

In this study, we tested to what extent smoking-specific parenting and changes in parenting are related to adolescents’ smoking trajectories. Data were used from a four-wave prospective study including 428 adolescents (aged M = 15.2; SD = 0.60). Latent Class Growth Analyses were conducted to identify trajectories. Multinomial Logistic Regression Analyses were executed to examine the relations between parenting and class membership. Longitudinal cross-lagged models were tested to examine causal predominance between parenting and smoking. Four trajectories were found, consisting of Non-smokers, Increasers, Stable smokers and Decreasers. Quality of parental smoking-specific communication was strongly related to the membership in different trajectories. Along with the cross-lagged associations demonstrating that the quality of communication was predominantly related to future smoking rather than vice versa, these findings indicate that parents who talked about smoking in a constructive and respectful manner were more likely to have non-smoking children. In contrast, parents who talked often about smoking-related issues and increased these discussions over time were more likely to have smoking children; cross-lagged associations indicated that these findings could be best explained by children changing their parents. Having a non-smoking agreement was related to a lower risk in becoming a regular smoker.     

How do socially anxious women evaluate mimicry? A virtual reality study

Being subtly mimicked leads to more positive evaluations of the mimicker. Socially anxious individuals (SAs), however, should respond differently. SAs would probably either not process mimicry due to self-focused attention or not appreciate such social behaviour. Consequently, we hypothesised that they would not think more positively about a mimicking person. To test this prediction, 25 SAs and 25 non-anxious controls (NACs), all female, interacted with two virtual men (avatars) separately. One avatar mimicked the participant's head movements while giving an opinionated speech, whereas the other did not mimic. Afterwards, participants evaluated the speeches and the avatars. As predicted, NACs evaluated the mimicking avatar and his speech more positively than the non-mimicking avatar. SAs, on the other hand, evaluated both avatars and their speeches the same; comparable to how NACs evaluated the non-mimicking avatar. These results conform to the notion that mimicking does not have positive effects on SAs.     

Effects of a driver enforcement program on yielding to pedestrians

A driver-yielding enforcement program that included decoy pedestrians, feedback flyers, written and verbal warnings, and saturation enforcement for a 2-week period was evaluated in the city of Miami Beach using a multiple baseline design. During baseline, data were collected at crosswalks along two major corridors. Treatment was introduced first at selected crosswalks without traffic signals along one corridor. A week later, enforcement was shifted to crosswalks along the second corridor. Results indicated that the percentage of drivers yielding to pedestrians increased following the introduction of the enforcement program in each corridor and that these increases were sustained for a period of a year with minimal additional enforcement. The effects also generalized somewhat to untreated crosswalks in both corridors, as well as to crosswalks with traffic signals.     

The effect of low social support on short-term prognosis in patients following a first myocardial infarction

The objectives of the current study were (1) to assess adjustment in patients following a first myocardial infarction (MI) at 9 months compared with 4-6 weeks post-MI, (2) to examine the availability of and satisfaction with social support over time, and (3) to determine separate baseline psychosocial predictors of recurrent cardiac events. A questionnaire assessing post-traumatic stress disorder, anxiety, depression, health complaints, and social support, was distributed to consecutive patients 4-6 weeks and 9 months post-MI. Prior to assessment at follow-up, 8 (7%) of 112 patients had dropped out, and two had died due to cardiac causes. Objective clinical measures were obtained from medical records. There was an improvement in somatic and cognitive symptoms at follow-up, but no change in symptoms of arousal, depression, and anxiety. Half of the patients were afraid of a recurrent MI. There was a significant decrease in social support between baseline and follow-up, and lower social support at baseline was associated with a 10% increased risk of recurrent cardiac events at follow-up (OR: 0.90; 95% CI: 0.84 to 0.97) adjusting for all other variables. Some patients still experienced difficulties with psychosocial adjustment 9 months post-MI despite a reduction in somatic and cognitive symptoms. Social support decreased over time, which may have serious prognostic implications; lower social support at baseline was an independent predictor of recurrent events at 9 months. An important step for future research will be to investigate how social support can be enhanced in patients at risk.     

What does rapid automatized naming measure? A new RAN task compared to naming and lexical decision

The present research investigated the relationship between Rapid Automatized Naming (RAN) performance, letter-string reading measures of sight vocabulary (SV) and phonetic decoding (PD), and lexical decision. Criterion-based naming rates were obtained from three types of RAN tasks: digits, letters, and letter sounds. Latency measures were obtained from the naming of regular words, exception words, nonwords and pseudohomophones; as well as button press and verbal lexical decision tasks. Regression analyses supported the hypotheses that RAN-Letters latency reflects SV processing in that its variance is uniquely accounted for by exception word naming latency and button press lexical decision latency, and that RAN-Letter Sounds latency best reflects PD processing in that its variance is uniquely accounted for by pseudohomophone and nonword naming latency. Findings are discussed in light of what the RAN tasks are measuring, implications involving visual word recognition models of reading, and the utility of the new RAN-Letter Sounds task with respect to diagnostic and remediation applications.     

Comparison of isokinetic peak force and power in adults with partial and total blindness

For many populations the ability to move efficiently is compromised by an impaired muscular functioning. Strength development is necessary to overcome the effects of gravity to maintain posture and generate movement responses for mobility. The strength and power capabilities of individuals with total blindness (n = 12) were compared to those with partial vision (n = 12) to evaluate effects of vision on performance. Results indicate that (1) no significant differences were apparent between total blindness and partial vision, (2) significant sex differences were evident in each group, and (3) better performance was apparent at lower velocities. It was concluded that physical performance in individuals with blindness and partial vision are equally deficient.     

Cognitive behavioral therapy for compulsive buying disorder

To our knowledge, no psychotherapy treatment studies for compulsive buying have been published. The authors conducted a pilot trial comparing the efficacy of a group cognitive behavioral intervention designed for the treatment of compulsive buying to a waiting list control. Twenty-eight subjects were assigned to receive active treatment and 11 to the waiting list control group. The results at the end of treatment showed significant advantages for cognitive behavioral therapy (CBT) over the waiting list in reductions in the number of compulsive buying episodes and time spent buying, as well as scores on the Yale–Brown Obsessive Compulsive Scale—Shopping Version and the Compulsive Buying Scale. Improvement was well-maintained at 6-month follow-up. The pilot data suggests that a cognitive behavioral intervention can be quite effective in the treatment of compulsive buying disorder. This model requires further testing.
