The present study examined bidirectional effects between maternal and paternal parenting styles (authoritative, authoritarian, permissive) and infant temperament (negative affect, orienting/regulatory capacity, surgency) in a diverse sample of 201 mothers and 151 fathers. Using 3 waves of longitudinal data (prenatal, 6 months, and 18 months), this study examined (a) whether maternal and paternal parenting styles prospectively predicted infant temperament; (b) whether mother-and father-reported infant temperament domains predicted parenting styles at 18 months; and (c) whether infant temperament and parenting styles at 6 months predicted parent-reported externalizing and internalizing problem behaviors at 18 months. Mothers and fathers reported on their expected parenting styles at all three waves, infant temperament at 6 months, and their toddler's emerging internalizing and externalizing problems at 18 months. Prospective parenting style effects revealed that maternal authoritative and permissive parenting style predicted infant orienting/regulatory capacity. Child evocative effects indicated infant orienting/regulatory capacity and negative affect predicted greater maternal permissive parenting style. Significant prospective parenting style effects on infant temperament and child evocative effects on paternal parenting style were largely not observed. Several parenting styles and infant temperament domains at 6 months predicted toddlers' externalizing and internalizing problem behaviors but results differed by parent. Findings suggest maternal prenatal perceptions of parenting style predict infant temperament, but temperament can also affect subsequent parenting. More research is needed to identify fathers' bidirectional effects including how fathering is affected by their children's characteristics.

This study's findings suggest that patients may return to driving 2 weeks postoperatively from a right-sided hip arthroscopy procedure.

Objective External distraction appears to affect at least 6–9% of distraction-affected motor vehicle collisions. Billboards may be good models for studying external distraction in general, and it is also desirable to understand billboard-related distraction per se. However, there has not yet been a clear consensus on the scope of billboard-related distraction or its dynamics with respect to characteristics of drivers, billboards, traffic, and the roadway. To narrow these knowledge gaps, a systematic literature review was conducted on billboard-related changes in driver visual behavior. Methods A systematic literature search yielded 443 results, of which 8 studies met all inclusion criteria. Five studies meeting all inclusion criteria were later identified and added. Results were analyzed in terms of 4 categories of visual behavior: (1) gaze variability (GV), glance pattern activity (GPA), and percentage of time spent glancing at the forward roadway; (2) glances at unexpected drive-relevant stimuli; (3) glances at expected drive-relevant stimuli; and (4) glances at billboards. Results There was considerable evidence that about 10–20% of all glances at billboards were ≥0.75 s, that active billboards drew more glances and more long glances (≥0.75 s, ≥2.0 s) than passive billboards but did not attract a longer average glance, and that there was large variability among individual billboards within categories (e.g., active vs. passive). The extent to which billboards attracted glances ≥ 2.0 s was uncertain. There was tentative evidence that billboards did not affect GPA, glances at expected drive-relevant stimuli, or the proportion of time drivers spent glancing at the forward roadway and that they did affect vertical GV and glances at unexpected drive-relevant stimuli. Conclusions Generally, billboard-related distraction appeared to be minor and regulated by drivers as the demands of the driving task changed. However, this review’s findings suggest that this may not be true in all cases. Future research should emphasize the tails of the distribution in addition to average cases, in terms of both the analysis of visual behavior and the complexity of driving tasks. Further research is also needed to understand the effects of billboard design, driver characteristics, and road and traffic context.

Objective To determine the impact of personality on distracted driving behaviors. Method Participants included 120 drivers (48 teens, 72 older adults) who completed the 45-item Big Five Personality questionnaire assessing self-reported personality factors and the Questionnaire Assessing Distracted Driving (QUADD) assessing the frequency of distracted driving behaviors. Associations for all five personality traits with each outcome (e.g. number of times texting on the phone, talking on the phone, and interacting with the phone while driving) were analyzed separately for teens and older adults using negative binomial or Poisson regressions that controlled for age, gender and education. Results In teens, higher levels of openness and conscientiousness were predictive of greater reported texting frequency and interacting with a phone while driving, while lower levels of agreeableness was predictive of fewer reported instances of texting and interacting with a phone while driving. In older adults, greater extraversion was predictive of greater reported talking on and interacting with a phone while driving. Other personality factors were not significantly associated with distracted driving behaviors. Conclusions Personality traits may be important predictors of distracted driving behaviors, though specific traits associated with distracted driving may vary across age groups. The relationship between personality and distracted driving behaviors provides a unique opportunity to target drivers who are more likely to engage in distracted driving behavior, thereby increasing the effectiveness of educational campaigns and improving driving safety.
