A prospective study of psychophysiological arousal, acute stress disorder, and posttraumatic stress disorder

This study investigated the role of acute arousal in the development of posttraumatic stress disorder (PTSD). Hospitalized motor-vehicle-accident survivors (n = 146) were assessed for acute stress disorder (ASD) within 1 month of the trauma and were reassessed (n = 113) for PTSD 6 months posttrauma. Heart rate (HR) and blood pressure (BP) were assessed on the day of hospital discharge. Participants with subclinical ASD had higher HR than those with ASD and no ASD. Participants who developed PTSD had higher HR in the acute posttrauma phase than those without PTSD. Diagnosis of ASD and resting HR accounted for 36% of the variance of the number of PTSD symptoms. A formula composed of a diagnosis of ASD or a resting HR of > 90 beats per minute possessed strong sensitivity (88%) and specificity (85%) in predicting PTSD. These findings are discussed in terms of acute arousal and longer term adaptation to trauma.     

Disentangling empowerment: Considering the role of employee perceptions in adaptive selling

As more jobs require employees to continually learn and adapt, empowering employees to adopt learning goals becomes a competitive advantage. Although research has identified key leadership behaviors that empower employees, the relationship between managers and empowered employees is ongoing and dynamic. Therefore, it is important to understand how key leadership behaviors interact with employees in their current state of empowerment to influence learning and performance. In this paper, we draw from self-determination theory to argue that the way employees perceive a given leadership behavior will differ by dimension of empowerment, and these perceptions impact their intrinsic motivation to learn. Specifically, employees who are high in competence and impact will perceive the leadership behavior of goal clarity as controlling, and be less likely to set learning goals, while those who are high in autonomy and meaning will perceive the same behavior as supportive, and be more likely to set learning goals. In a time-lagged study of 349 salespeople, we find that goal clarity acts as a boundary condition by weakening the relationship between empowerment and learning goal orientation (LGO) for those high on the competence and impact dimensions. As hypothesized, we find that the same behavior of goal clarity actually strengthens the relationship for those high on the autonomy and meaning dimensions. Further, we provide theoretical and empirical evidence that LGO mediates the relationship between empowerment and adaptive selling.     

Risk and Resistance Factors Associated with Paternal Adjustment to Obstetrical Brachial Plexus Injuries

This study aimed to identify risk and resistance factors associated with the psychological adjustment of fathers of children with obstetrical brachial plexus injuries (OBPI). Participants were 34 fathers of children with OBPI recruited from an Australian OBPI clinic. Measures completed were OBPI severity, disability related stress, family functioning and social support. Together the risk and resistance factors of severity and family functioning accounted for 28 % of the total variance in paternal psychological adjustment. Family functioning explained 12 % of the variance in psychological adjustment in addition to that explained by severity. These findings highlight the importance of considering paternal perceptions of OBPI severity and family functioning when providing health care to families of children with OBPI.     

The Rosenberg Self-Esteem Scale: A Bifactor Answer to a Two-Factor Question?

Despite its long-standing and widespread use, disagreement remains regarding the structure of the Rosenberg Self-Esteem Scale (RSES). In particular, concern remains regarding the degree to which the scale assesses self-esteem as a unidimensional or multidimensional (positive and negative self-esteem) construct. Using a sample of 3,862 high school students in the United Kingdom, 4 models were tested: (a) a unidimensional model, (b) a correlated 2-factor model in which the 2 latent variables are represented by positive and negative self-esteem, (c) a hierarchical model, and (d) a bifactor model. The totality of results including item loadings, goodness-of-fit indexes, reliability estimates, and correlations with self-efficacy measures all supported the bifactor model, suggesting that the 2 hypothesized factors are better understood as “grouping” factors rather than as representative of latent constructs. Accordingly, this study supports the unidimensionality of the RSES and the scoring of all 10 items to produce a global self-esteem score.     

Time,Money, or Gender? Predictors of the Division of Household Labour Across Life Stages

Drawing on a life course perspective and data gathered during three developmental periods—the transition to adulthood (age 25; n = 168), young adulthood (age 32; n = 337), and midlife (age 43; n = 309), we explored patterns of division of household labour among Canadian men and women. We also investigated associations among housework responsibility and variables representing time availability (i.e., work hours), relative resource (i.e., earning a greater share of income in a relationship), and gender constructionist perspectives (i.e., marital status and raising children) at three life course stages. Results indicated women performed more housework than men at all ages. Regression analyses revealed housework responsibility was most reliably predicted by relative income and gender at age 25; work hours and raising children at age 32; and work hours, relative income, and gender at age 43. Gender moderated the influence of raising children at age 32. Overall, the relative resource perspective was supported during the transition to adulthood and in midlife, the time availability perspective was supported in young adulthood and in midlife, and certain elements of the gender constructionist perspective were supported at all life stages. The present study contributes to the division of household labour literature by disentangling the predictive power of time, resource, and gender perspectives on housework at distinct life stages.     

Reflective and ruminative processing of positive emotional memories in bipolar disorder and healthy controls

Recent evidence suggests that reflective (i.e., distanced-why), as compared to ruminative (i.e., immersed-why), processing of negative memories is associated with reductions in negative affect. The present study extended this line of work by examining the effect of these two processing conditions on positive memories among persons with bipolar disorder (BD; n = 27) and a healthy control group (CT; n = 27). After a resting baseline period, participants were instructed to recall a happy autobiographical memory. Using a within-subjects design, participants were asked to process the happy memory in two different experimental conditions (reflective, ruminative) while their experiential, behavioral, and autonomic responses were measured. Consistent with hypotheses, reflective processing was associated with lower self-reported positive affect, positive thoughts, and heart rate compared to ruminative processing for all participants. When current symptoms were controlled for, BD participants reported greater positive affect across both conditions relative to CT participants. Prospective studies are needed to test the extent to which processing of positive emotion contributes to the course of symptoms in bipolar disorder.
