Not Me, But Reflects Me: Validating a Simple Implicit Measure of Psychological Capital.

We propose the recently introduced implicit measure of psychological capital (PsyCap), the Implicit Psychological Capital Questionnaire (I-PCQ; Harms & Luthans, 2012), can provide a needed valid alternative to the self-report Psychological Capital Questionnaire (PCQ). We explain the development of the I-PCQ items, assess the structural validity of the instrument, test its vulnerability to response distortion, and assess its capacity to predicting work attitudes and behaviors vis-à-vis the PCQ and Big Five personality facets. We found that the I-PCQ demonstrated acceptable structural validity that was consistent with and added to prior theorizing, was resistant to response distortion, and predicted work outcomes above and beyond the widely used self-report PCQ and Big Five personality traits. We conclude that the I-PCQ represents a valid, easily administered measure of psychological capital that minimizes problems associated with self-reports and is appropriate for use in work settings.

Genetic analysis of sow longevity and sow lifetime reproductive traits using censored data.

Sow longevity is a key component for efficient and profitable pig farming; however, approximately 50% of sows are removed annually from a breeding herd. There is no consensus in the scientific literature regarding a definition for sow longevity; however, it has been suggested that it can be measured using several methods such as stayability and economic indicators such as lifetime piglets produced. Sow longevity can be improved by genetic selection; however, it is rarely included in genetic evaluations. One reason is elongated time intervals required to collect complete lifetime data. The effect of genetic parameter estimation software in handling incomplete data (censoring) and possible early indicator traits were evaluated analysing a 30% censored data set (12 725 pedigreed Landrace × Large White sows that included approximately 30% censored data) with DMU6, THRGIBBS1F90 and GIBBS2CEN. Heritability estimates were low for all the traits evaluated. The results show that the binary stayability traits benefited from being analysed with a threshold model compared to analysing with a linear model. Sires were ranked very similarly regardless if the program handled censoring when all available data were included. Accumulated born alive and stayability were good indicators for lifetime born alive traits. Number of piglets born alive within each parity could be used as an early indicator trait for sow longevity.

The Abbreviated Character Strengths Test (ACST): A Preliminary Assessment of Test Validity.

The 24-item Abbreviated Character Strengths Test (ACST) was developed to efficiently measure character strengths (Peterson, Park, & Castro, 2011 ). However, its validity for this purpose has not yet been sufficiently established. Using confirmatory factor analysis to test a series of structural models, only a modified bifactor model showed reasonably acceptable fit. Further analyses of this model failed to demonstrate measurement invariance between male and female respondents. Relationships between ACST dimension and Big Five personality trait scores were generally weak-to-moderate, and support for hypotheses regarding each ACST virtue's expected correspondence with specific Big Five dimensions was mixed. Finally, scores on ACST dimensions accounted for a combined 12% of the variance in satisfaction with life scores, after controlling for socially desirability. Although an abbreviated measure of character strengths represents a practical need, considerable improvements to the ACST are needed for it to adequately meet this purpose.

Using retest-adjusted correlations as indicators of the semantic similarity of items.

Determining whether different items provide the same information or mean the same thing within a population is a central concern when determining whether different scales or constructs are overlapping or redundant. In the present study, we suggest that retest-adjusted correlations provide a valuable means of adjusting for item-level unreliability. More exactly, we suggest dividing the estimated correlation between items X and Y measured over measurement interval |d| by the average retest correlations of the items over the same measurement interval. For instance, if we correlate scores from items X and Y measured 1 week apart, their retest-adjusted correlation is estimated by using their 1-week retest correlations. Using data from four inventories, we provide evidence that retest-adjusted correlations are significantly better predictors of whether two items are consensually regarded as "meaning the same thing" by judges than raw-score correlations. The results may provide the first empirical evidence that Spearman's (1904, 1910) suggested reliability adjustment do-in certain (perhaps very constrained!) circumstances-improve upon raw-score correlations as indicators of the informational or semantic equivalence of different tests.

A meta-analysis on the crossover of workplace traumatic stress symptoms between partners.

Workers who are exposed to severe situations such as death, harassment, and others' suffering at work are vulnerable to symptoms of posttraumatic stress disorder (PTSD) and severe distress. This distress may extend to their intimate partners, despite their lack of firsthand experience with the traumatic stressors. Although theory and empirical research suggest that employees' traumatic distress can transmit to their partners, the magnitude of these effects and when, how, and why intimate partners develop secondary traumatic symptoms and distress are not as clear. Drawing from crossover theory as an organizing framework (Westman, 2001), our meta-analysis of 276 articles indicates that the relationship between employee PTSD/distress and spouse PTSD/distress is as strong as the relationship between employee trauma exposure and employee PTSD/distress (ρ = .26), suggesting that workers' PTSD/distress is as distressing for partners as the traumatic stressors are for workers encountering them firsthand. Our moderation tests further revealed that the trauma-exposed workers' vulnerability to traumatic stress symptoms was stronger in military than in nonmilitary settings, whereas the extent to which their symptoms crossover to their intimate partners did not vary across occupations. Mediation tests suggest that traumatic stress crossover is partially explained by the worsened quality of the couple's relationship (e.g., increased social support burden and undermining), consistent with the crossover via couple interaction explanation in crossover theory. On the other hand, there was mixed support for the mediating role of the partner's empathy, indicating further research and clarification are needed. Implications for crossover theory and practice are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Development of the Hogan Personality Content Single-Items Inventory.

The Hogan Personality Inventory (HPI) and Hogan Developmental Survey (HDS) are among the most widely used and extensively well-validated personality inventories for organizational applications; however, they are rarely used in basic research. We describe the Hogan Personality Content Single-Items (HPCS) inventory, an inventory designed to measure the 74 content subscales of the HPI and HDS via a single-item each. We provide evidence of the reliability and validity of the HPCS, including item-level retest reliability estimates, both self-other agreement and other-other (or observer) agreement, convergent correlations with the corresponding scales from the full HPI/HDS instruments, and analyze how similarly the HPCS and full HPI/HDS instruments relate to other variables. We discuss situations where administering the HPCS may have certain advantages and disadvantages relative to the full HPI and HDS. We also discuss how the current findings contribute to an emerging picture of best practices for the development and use of inventories consisting of single-item scales.

Neighborhood walkability, physical activity and changes in glycemic markers in people with type 2 diabetes: The Hoorn Diabetes Care System cohort.

Studies investigating neighborhood walkability and physical activity in people with type 2 diabetes (T2D) mainly used self-report measures, and only few studies assessed the association with glycemic control. This study assessed the associations between objectively measured (i.e. GIS based) and subjectively measured (i.e. questionnaire-based) neighborhood walkability and changes in glycemic markers in people with T2D, and whether this association was mediated by device-measured physical activity (PA), in the Diabetes Care System Cohort (n = 1230). Neither objective or subjectively measured walkability was associated with glycemic control. In mediation analyses we observed no overall mediation by PA.

Prostaglandin involvement in hypothalamic control of gonadotropin and prolactin release.

Prostaglandin E(2) (PGE(2)) injected into the third ventricle of ovariectomized rats increased plasma luteinizing hormone dramatically and follicle stimulating hormone slightly. PGE(1) elevated prolactin; PGF(1alpha) or PGF(2alpha) had no effect. PGE(2) or PGE(1) injected directly into the anterior pituitary were ineffective. These results suggest that specific prostaglandins act at the hypothalamus to control pituitary hormone release.

Shall we serve the dark lords? A meta-analytic review of psychopathy and leadership.

Both scholars and the popular press have expressed concern regarding the potential prevalence of individuals with psychopathic tendencies in corporate leadership positions and the negative effects they may have on both individual workers and their organizations as a whole. However, research to date has been inconclusive as to whether such individuals are more likely to emerge as leaders or whether they are (in)effective leaders. To clarify the state of the literature, we conducted a meta-analysis on the association between psychopathic personality characteristics and leadership emergence, leadership effectiveness, and transformational leadership. Our results, based on data from 92 independent samples, showed a weak positive correlation for psychopathic tendencies and leadership emergence, a weak negative association for psychopathic tendencies and leadership effectiveness, and a moderate negative correlation for psychopathic tendencies and transformational leadership. Subgroup analyses on methodological factors did not indicate any differences from the main results. However, moderator analyses showed a gender difference in these associations such that psychopathic tendencies in men were weakly positively correlated with leadership emergence and effectiveness and negatively correlated with transformational leadership, while psychopathic tendencies in women were negatively associated with effectiveness and transformational leadership, and largely unassociated with emergence. In addition, small but consistent curvilinear associations were found for all leadership criteria. Overall, these results suggest that concern over psychopathic tendencies in organizational leaders may be overblown, but that gender can function to obscure real effects.

Exploring the relative importance of normative and distinctive organizational preferences as predictors of work attitudes.

Profile approaches to operationalizing person-organization (P-O) fit as the within-person correlation between an individual's ideal organization characteristics and their actual organization characteristics regularly find strong associations between P-O fit and an individual's work attitudes. However, profile correlation indices and other overall indices of P-O fit regularly confound normative and distinctive components of fit-that is: the extent to which the person's organization culture fits the culture that would be preferred by the average person, and the extent to which their organization fits an individual's idiosyncratic preferences. Here, we show how these two normative and distinctive P-O fits can be differentiated and related to an individual's attitudes about their organization experience. Utilizing data from 723 participants from four samples, we show that the degree to which an individual's description of their organizational culture corresponds to the normative ideal organizational culture may account for nearly all of the large associations regularly found between overall P-O fit indices and positive workplace attitudes. In contrast, the degree of fit between an individual's work environment and their distinctive or idiosyncratic preferences may play a relatively small role in predicting the positive workplace attitudes. We discuss broader implications for the design of organizational cultures and the more general understanding of the nature of P-O fit. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Estimating the reliability of emotion measures over very short intervals: The utility of within-session retest correlations.

Short measures are commonly used when conducting research involving emotions. However, obtaining appropriate estimates of reliability for short measures is traditionally problematic and is a reoccurring concern in emotion research. To address this issue, we compare the within-session test-retest and factor analysis methods for estimating the reliability of items in the Positive and Negative Affect Schedule-Expanded Form. Results indicate that within-session test-retest (rXX(d)) estimates outperform the factor analysis method by demonstrating stronger relationships with item properties relevant to reliability and validity-related criteria. In addition, rXX(d) estimates appropriately generalize across samples with various instruction stems and prevent corrections for attenuation greater than 1.00. Therefore, we encourage researchers to use the corresponding average item-level rXX(d) estimates reported here to correct for attenuation when examining single items from the Positive and Negative Affect Schedule-Expanded Form if a test-retest design is not feasible.

Evidence of Non-Corresponsive Causal Relationships Between Personality Traits and Social Power Over Time.

Although the effects of personality traits on social environments are regularly thought to mirror the effects of social environments on personality traits, the causal dynamics existing between personality traits and social power may represent an important exception. Using a sample of 181 fraternity and sorority members surveyed over a year, we show that agentic traits are more likely to show cross-sectional associations with social power, and may increase from the experience of social power. However, increases in social power over a year are predicted better by communal characteristics. The findings are consistent with the understanding that social power acts as a disinhibitor allowing people to enact their desires with less risk and greater efficacy, but is differentially afforded to individuals perceived as likely to promote the goals of others. We discuss the conditions that may need to exist for personality traits and environments to show corresponsive relationships more generally.

Development and Validation of the Five-by-Five Resilience Scale.

This article introduces a new measure of resilience and five related protective factors. The Five-by-Five Resilience Scale (5×5RS) is developed on the basis of theoretical and empirical considerations. Two samples ( N = 475 and N = 613) are used to assess the factor structure, reliability, convergent validity, and criterion-related validity of the 5×5RS. Confirmatory factor analysis supports a bifactor model. The 5×5RS demonstrates adequate internal consistency as evidenced by Cronbach's alpha and empirical reliability estimates. The 5×5RS correlates positively with the Connor-Davidson Resilience Scale (CD-RISC), a commonly used measure of resilience. The 5×5RS exhibits similar criterion-related validity to the CD-RISC as evidenced by positive correlations with satisfaction with life, meaning in life, and secure attachment style as well as negative correlations with rumination and anxious or avoidant attachment styles. 5×5RS scores are positively correlated with healthy behaviors such as exercise and negatively correlated with sleep difficulty and symptomology of anxiety and depression. The 5×5RS incrementally explains variance in some criteria above and beyond the CD-RISC. Item responses are modeled using the graded response model. Information estimates demonstrate the ability of the 5×5RS to assess individuals within at least one standard deviation of the mean on relevant latent traits.

Randomised comparison of three types of continuous anterior abdominal wall block after midline laparotomy for gynaecological oncology surgery.

Effective analgesia after midline laparotomy surgery is essential for enhanced recovery programs. We compared three types of continuous abdominal wall block for analgesia after midline laparotomy for gynaecological oncology surgery. We conducted a single-centre, double-blind randomised controlled trial. Ninety-four patients were randomised into three groups to receive two days of programmed intermittent boluses of ropivacaine (18 ml 0.5% ropivacaine every four hours) via either a transversus abdominis plane (TAP) catheter, posterior rectus sheath (PRS) catheter, or a subcutaneous (SC) catheter. All groups received patient-controlled analgesia with morphine, and regular paracetamol and non-steroidal anti-inflammatory medication. Measured outcomes included analgesic and antiemetic usage and visual analog scores for pain, nausea, vomiting, and satisfaction. Eighty-eight patients were analysed (29 SC, 29 PRS and 30 TAP). No differences in the primary outcome were found (median milligrams morphine usage on day two SC 28, PRS 25, TAP 21, P=0.371). There were differences in secondary outcomes. Compared with the SC group, the TAP group required less morphine in recovery (0 mg versus 6 mg, P=0.01) and reported less severe pain on day one (visual analog scores 36.3 mm versus SC 55 mm, P=0.04). The TAP group used fewer doses of tropisetron on day one compared with the PRS group (8 versus 21, P=0.016). Programmed intermittent boluses of ropivacaine delivered via PRS, TAP and SC catheters can be provided safely to patients undergoing midline laparotomy surgery. Initially TAP catheters appear superior, reducing early opioid and antiemetic requirements and severe pain, but these advantages are lost by day two.

Becoming the Harvard man: person-environment fit, personality development, and academic success.

The continuity and change of the needs and evaluations of the college environment and person-environment fit (PE fit) with the college environment were studied in a 4-year longitudinal study of students (N = 191). Perceptions of the environment changed more dramatically than corresponding self-perceived needs. PE fit demonstrated moderate levels of consistency over the 4-year span, but no significant increases in mean levels were found over time. Antecedents to PE fit in the college environment included both intelligence and openness to experience. Outcomes associated with PE fit included changes in personality traits linked to openness to experience and higher academic achievement. The implications of the findings for personality development and the relationship of PE fit to successful outcomes are discussed.

Separating the why from the what: Reply to Jonas and Markon(2015).

In this response to the commentary offered by Jonas and Markon (2015) on our earlier work, we address points of agreement and disagreement on the nature and utility of functionalist and descriptivist accounts of personality. Specifically, we argue that explanatory and conceptual parsimony is more appropriate than statistical parsimony for evaluating the proposed models, discuss ways in which functionalist and descriptivist approaches can complement one another, and provide some cautions about interpreting latent traits.

Socio-cultural factors influencing prevention and treatment of tuberculosis in immigrant and Aboriginal communities in Canada.

This multi-method study used a participatory action research approach to examine the complex net of socio-cultural factors that influenced behaviour related to tuberculosis (TB) prevention and treatment in the 10 highest risk cultural groups consisting of immigrant and Aboriginal populations in the province of Alberta, Canada. Trained community research associates collected qualitative interview data and helped with interpretation and evaluation. A community advisory committee established foundation principles and monitored the ethical and cultural appropriateness of the research process. A key finding is that although patients with active disease learn about TB from health professionals, people in high-risk populations need to learn more about TB transmission and prevention prior to contact. This is particularly important given that lack of knowledge of TB was strongly associated with negative attitudes towards TB and a worse experience of the disease. The study results underline the need for accessible and culturally appropriate health education about TB in the high risk groups. This can be accomplished in collaboration with lay people, particularly those who have recovered from active TB, their family members and health workers from the community.

Effects of leptin on gonadotropin-releasing hormone release from hypothalamic-infundibular explants and gonadotropin release from adenohypophyseal primary cell cultures: further evidence that fully nourished cattle are resistant to leptin.

In rodents and pigs, leptin stimulates the release of gonadotropin-releasing hormone (GnRH) from hypothalamus, gonadotropins from adenohypophyseal (AP) explants and cells, and luteinizing hormone (LH) from full-fed animals. In the current studies, we investigated whether leptin could stimulate the release of GnRH from bovine hypothalamic-infundibular (HYP) explants and gonadotropins from bovine adenohypophyseal cells. In Experiment 1A, HYP explants collected from 17 bulls and seven steers were incubated with Krebs-Ringer bicarbonate buffer (KRB) containing 0, 10, 100, or 1000 ng/ml recombinant ovine leptin (oleptin) for 30 min after a 3-h period of equilibration. None of the doses of leptin affected (P > 0.05) GnRH release into the media. In Experiment 1B, HYP explants collected from six steers were incubated with KRB containing 0 or 1000 ng/ml oleptin for two consecutive 30-min periods and challenged with 60 mM K(+) afterwards. Leptin did not affect (P > 0.05) basal or K(+)-stimulated release of GnRH. In Experiment 2, adenohypophyses from steers were collected at slaughter and cells dispersed and cultured for 4 days. On day 5, cells were treated with media alone (control) or media containing 10(-11), 10(-10), 10(-9), and 10(-8)M oleptin. Three independent replications were performed. None of the doses of leptin stimulated (P > 0.05) the release of LH. Although leptin at 10(-11), 10(-10), and 10(-9)M increased (P < 0.03) slightly the release of FSH compared to control-treated cells in one replicate, this effect was not confirmed in the other two replicates. Results support the hypothesis that leptin has limited effects on the release of GnRH and gonadotropins in full-fed cattle and reiterate important species differences in responsiveness to leptin.

How functionalist and process approaches to behavior can explain trait covariation.

Factors identified in investigations of trait structure (e.g., the Big Five) are sometimes understood as explanations or sources of the covariation of distinct behavioral traits, as when extraversion is suggested to underlie the covariation of assertiveness and sociability. Here, we detail how trait covariation can alternatively be understood as arising from units common to functionalist and process frameworks, such as self-efficacies, expectancies, values, and goals. Specifically, the expected covariation between 2 behavioral traits should be increased when a specific process variable tends to indicate the functionality of both traits simultaneously. In 2 empirical illustrations, we identify a wide array of specific process variables associated with several Big Five-related behavioral traits simultaneously, and which are thus likely sources of their covariation. Many of these, such as positive interpersonal expectancies, self-regulatory skills, and preference for order, relate similarly to a broad range of trait perceptions in both studies, and across both self- and peer-reports. We also illustrate how this understanding of trait covariation provides a somewhat novel explanation of why some traits are uncorrelated. As we discuss, a functionalist understanding of trait covariation as arising through functionalist or process variables has implications for many basic issues in personality psychology, such as how personality traits should be measured, mechanisms for personality stability and change, and the nature of personality traits more generally.
