Post-traumatic Growth in Breast Cancer Survivors: New Insights into its Relationships with Well-Being and Distress

Research investigating possible relations between Post-traumatic growth (PTG) and clinical indexes—such as psychosocial distress, physical and psychological well-being—is lacking in medical settings. The aim of this study was to look into such relationships in breast cancer survivors (Bcs) and in healthy control subjects who experienced other stressful events. Sixty Bcs and 60 healthy women reporting other stressful events were compared according to the following scales: Post-traumatic Growth Inventory, Psychological Well-being Scales (PWB), Symptom Questionnaire and Psychosocial Index. Bcs reported significantly higher levels of PTG and distress, and lower levels of PWB compared to healthy women. Bcs with high levels of PTG showed increased levels of physical well-being and decreased distress. Healthy women under stressful circumstances reporting high levels of PTG showed increased levels of PWB. PTG levels were higher in Bcs and associated with decreased psychological distress and somatisation. These results carry important implications for clinical assessment, as well as for planning interventions to improve well-being and resilience in oncology.     

The early development of human mirror mechanisms: evidence from electromyographic recordings at 3 and 6 months

In primates and adult humans direct understanding of others' action is provided by mirror mechanisms matching action observation and action execution (e.g. Casile, Caggiano & Ferrari, 2011). Despite the growing body of evidence detailing the existence of these mechanisms in the adult human brain, their origins and early development are largely unknown. In this study, for the first time, electromyographic (EMG) measures were used to shed light on the emergence of mirror motor mechanisms in infancy. EMG activity was recorded while 6‐ and 3‐month‐old infants watched two videos displaying an agent reaching for, grasping and bringing an object either to the mouth or to the head. Results indicate that the motor system of 6‐month‐olds, but not 3‐month‐olds, was recruited and selectively modulated during observation of the goal‐directed actions, favoring the idea that mirror mechanisms driving action understanding gradually emerge during early development.     

Correction of a Technical Error in the Golf Swing: Error Amplification Versus Direct Instruction

Performance errors drive motor learning for many tasks. The authors' aim was to determine which of two strategies, method of amplification of error (MAE) or direct instruction (DI), would be more beneficial for error correction during a full golfing swing with a driver. Thirty-four golfers were randomly assigned to one of three training conditions (MAE, DI, and control). Participants were tested in a practice session in which each golfer performed 7 pretraining trials, 6 training-intervention trials, and 7 posttraining trials; and a retention test after 1 week. An optoeletronic motion capture system was used to measure the kinematic parameters of each golfer's performance. Results showed that MAE is an effective strategy for correcting the technical errors leading to a rapid improvement in performance. These findings could have practical implications for sport psychology and physical education because, while practice is obviously necessary for improving learning, the efficacy of the learning process is essential in enhancing learners' motivation and sport enjoyment.     

Campus Responses to Dating Violence and Sexual Assault: Information from University Representatives

Universities have an obligation to provide student victims with services that are easily accessible. This study focused on the provision of sexual assault and dating violence services of large, public 4-year institutions, as reported by university representatives. The sample included security officers from 45 universities who completed phone interviews between February and May 2013. Phone interviews consisted of 15 open-ended questions. The findings point to highly variable practices and services offered across campuses. The services most frequently reported by university representatives include counseling and police services. The findings also suggest that public 4-year institutions not only offer varied levels of services, but such services might not be readily available to student victims. Although many representatives identified underserved groups and suggestions for improvement, a sizable portion did not acknowledge any. Further, university representatives did not distinguish between services provided for dating violence and sexual assault.     

Testing the effects of end-goal during reach-to-grasp movements in Parkinson’s disease

Previous evidence suggests that hand shaping during reaching is modulated by the presence and the nature of the end-goal following object’s grasp. Here we test whether such modulation is maintained in Parkinson’s disease (PD). Six participants with PD and six healthy participants took part in the study. Participants were requested to reach towards a bottle filled with water, and then: (1) grasp it without performing any subsequent action; (2) grasp it and place it accurately on a target area; (3) grasp it and pour its contents within a container. The results showed that participants shaped their hand differently depending on the presence or absence of an action following object’s grasp. However, the request to perform an action after grasp determined a modulation of hand kinematics which was delayed for PD than for control participants. Further, whereas for control participants the nature of the end-goal determined a modulation of hand shaping, for PD patients such modulation was not evident. Data are discussed in terms of the role played by basal ganglia in implementing anticipatory mechanisms for the control of manipulative activities. We contend that in PD patients these mechanisms are not totally compromised, but their implementation depends on the action information that has to be anticipated.     

Psychophysiological reactivity to sleep-related emotional stimuli in primary insomnia

The present study examined psychophysiological reactivity to emotional stimuli related and non-related to sleep in people with primary insomnia (PPI) and in good sleepers (GS). Twenty-one PPI and 18 GS were presented with five blocks of neutral, negative, positive, sleep-related negative and sleep-related positive pictures. During the presentation of the pictures, facial electromyography (EMG) of the corrugator and the zygomatic muscles, heart rate (HR) and cardiac vagal tone (CVT) were recorded. Subjective ratings of the stimuli were also collected. We found that only PPI exhibited greater inhibition of the corrugator activity in response to sleep-related positive stimuli compared to the other blocks of stimuli. Furthermore, PPI rated the sleep-related negative stimuli as more unpleasant and arousing and showed higher CVT in response to all stimuli as compared to GS. Results were interpreted as indicating that PPI exhibit craving for sleep-related positive stimuli, and also hyper-arousability in response to sleep-related negative stimuli, as compared to GS. Our results suggest that psychological treatment of insomnia could benefit by the inclusion of strategies dealing with emotional processes linked with sleep processes.     

Prevalence and Correlates of Posttraumatic Stress and Postpartum Depression in Parents of Infants in the Neonatal Intensive Care Unit (NICU)

The purpose of this study was to assess the prevalence and correlates of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) in mothers and fathers, and postpartum depression (PPD) in mothers, of infants in the Neonatal Intensive Care Unit (NICU). 86 mothers and 41 fathers completed measures of ASD and of parent perception of infant medical severity 3–5 days after the infant’s NICU admission (T1), and measures of PTSD and PPD 30 days later (T2). 35% of mothers and 24% of fathers met ASD diagnostic criteria at T1, and 15% of mothers and 8% of fathers met PTSD diagnostic criteria at T2. PTSD symptom severity was correlated with concurrent stressors and family history of anxiety and depression. Rates of ASD/PTSD in parents of hospitalized infants are consistent with rates in other acute illness and injury populations, suggesting relevance of traumatic stress in characterizing parent experience during and after the NICU.
