Social desirability in personality inventories: symptoms, diagnosis and prescribed cure

An analysis of social desirability in personality assessment is presented. Starting with the symptoms, Study 1 showed that mean ratings of graded personality items are moderately to strongly linearly related to social desirability (Self Deception, Impression formation, and the first Principal Component), suggesting that item popularity may be a useful heuristic tool for identifying items which elicit socially desirable responding. We diagnose the cause of socially desirable responding as an interaction between the evaluative content of the item and enhancement motivation in the rater. Study 2 introduced a possible cure; evaluative neutralization of items. To test the feasibility of the method lay psychometricians (undergraduates) reformulated existing personality test items according to written instructions. The new items were indeed lower in social desirability while essentially retaining the five factor structure and reliability of the inventory. We conclude that although neutralization is no miracle cure, it is simple and has beneficial effects.

Awareness among nurses about reporting of adverse drug reactions in Sweden

BACKGROUND

The purpose of this study was to investigate awareness among nurses regarding their new role as reporters of adverse drug reactions in Sweden and factors that may influence reporting by nurses.

METHODS

In 2007, all nurses were included in the adverse drug reaction reporting scheme in Sweden. A questionnaire was sent to 753 randomly selected nurses in September 2010.

RESULTS

Of the 453 (60%) responding nurses, 265 (58%) were aware that nurses were included in the reporting of adverse drug reactions. Sixty-one nurses (14%) stated that they had reported an adverse drug reaction. Fifteen percent (n = 70) of the respondents had received training about reporting of adverse drug reactions. Almost one third of these (n = 21, 30%) had reported an adverse drug reaction on at least one occasion. Among nurses without training, a smaller proportion (n = 40, 11%, P < 0.05) had reported an adverse drug reaction on at least one occasion. The two factors considered most important by nurses for reporting were the severity of the adverse drug reaction and if the reaction was to a newly approved drug. A majority of the nurses (n = 397, 88%) were interested in a training course in pharmacology as part of their ongoing professional development. One third (32%) of all nurses stated that one reason for not reporting a suspected adverse drug reaction was that the physician responsible did not regard the reaction necessary to report.

CONCLUSION

We found that more than half of the study population of nurses in Sweden were aware of their new role as reporters of adverse drug reactions, but few of the responding nurses had reported an adverse drug reaction. Given that training seems to be associated with high reporting frequency, we suggest more training in pharmacovigilance for nurses.

The Effect of Response Style on Self-Reported Conscientiousness Across 20 Countries

Rankings of countries on mean levels of self-reported Conscientiousness continue to puzzle researchers. Based on the hypothesis that cross-cultural differences in the tendency to prefer extreme response categories of ordinal rating scales over moderate categories can influence the comparability of self-reports, this study investigated possible effects of response style on the mean levels of self-reported Conscientiousness in 22 samples from 20 countries. Extreme and neutral responding were estimated based on respondents’ ratings of 30 hypothetical people described in short vignettes. In the vignette ratings, clear cross-sample differences in extreme and neutral responding emerged. These responding style differences were correlated with mean self-reported Conscientiousness scores. Correcting self-reports for extreme and neutral responding changed sample rankings of Conscientiousness, as well as the predictive validities of these rankings for external criteria. The findings suggest that the puzzling country rankings of self-reported Conscientiousness may to some extent result from differences in response styles.

The Swedish Depressive Personality Disorder Inventory: psychometrics and clinical correlates from a DSM-IV and proposed DSM-5 perspective

BACKGROUND

Depressive personality is commonly seen in clinical practice, and today only one exclusive self-report instrument-the Depressive Personality Disorder Inventory (DPDI)-is available for its assessment based on the DSM-IV description of the construct.

AIMS

The purpose of this research was to evaluate a Swedish version of this measure (DPDI-Swe) in terms of its reliability, internal structure, and convergent validity using related variables from the DSM-IV criteria for depressive personality disorder (DPD) and the proposed DPD trait set for DSM-5.

METHODS

A non-clinical sample of 255 adults in southern Sweden completed a self-report package, which, in addition to DPD, included the assessment of self-esteem, optimism, hope, rumination, worry, depression, and anxiety. Quality of life was also measured.

RESULTS

Results indicated that the DPDI-Swe was internally consistent (α = 0.96). Exploratory factor analysis with oblique rotation yielded three components, together accounting for 48.21% of the variance in DPDI-Swe scores. There were strong positive associations between the DPDI-Swe and measures of depression, anxiety, rumination, and worry, and strong negative associations between the DPDI-Swe and measures of self-esteem, optimism, hope, and quality of life. These significant relationships remained, albeit slightly diminished, after statistically controlling for current depressed mood.

CONCLUSIONS AND CLINICAL IMPLICATIONS

The DPDI-Swe appears to be a reliable and valid measure of DPD, and it is available for clinical and research use.

Mixed Discriminatory Judgments of Individuals’ Warmth and Competence-Related Abilities

Although several studies have demonstrated that stereotypes can be mixed in terms of warmth and competence (e.g., cold but competent), the possibility of mixed discrimination has received very little attention so far. To this end, the present study investigated mixed discriminatory judgments of individuals. In two studies, the participants judged the empathic (warmth) and the cognitive (competence) ability of individuals who differed only in whether they belonged to a group typically stereotyped as warm but incompetent or cold but competent. Study 1 compared Greeks with Germans (nationality) and Study 2 preschool teachers with lawyers (occupation). In both studies, the judgments were discriminatory in a mixed pattern consistent with the groups’ stereotype content.

Substance abuse and psychiatric co-morbidity as predictors of premature mortality in Swedish drug abusers: a prospective longitudinal study 1970-2006

BACKGROUND

Few longitudinal cohort studies have focused on the impact of substances abused and psychiatric disorders on premature mortality. The aim of the present study was to identify predictors of increased risk of drug related death and non drug related death in substance abusers of opiates, stimulants, cannabis, sedatives/hypnotics, hallucinogens and alcohol over several decades.

METHODS

Follow-up study of a consecutive cohort of 561 substance abusers, admitted to a detoxification unit January 1970 to February 1978 in southern Sweden, and followed up in 2006. Demographic and clinical data, substance diagnoses and three groups of psychiatric diagnoses were identified at first admission. Causes of death were coded according to ICD-10 and classified as drug related deaths or non drug related deaths. To identify the incidence of some probable risk factors of drug related premature death, the data were subjected to a competing risks Cox regression analysis.

RESULTS

Of 561 patients in the cohort, 11 individuals had either emigrated or could not be located, and 204/561 patients (36.4%) were deceased by 2006. The cumulative risk of drug related death increased more in the first 15 years and leveled out later on when non drug related causes of death had a similar incidence. In the final model, male gender, regular use of opiates or barbiturates at first admission, and neurosis were associated with an increased risk of drug related premature death, while cannabis use and psychosis were associated with a decreased risk. Neurosis, mainly depression and/or anxiety disorders, predicted drug related premature death while chronic psychosis and personality disorders did not. Chronic alcohol addiction was associated with increased risk of non drug related death.

CONCLUSIONS

The cohort of drug abusers had an increased risk of premature death to the age of 69. Drug related premature death was predicted by male gender, the use of opiates or barbiturates and depression and anxiety disorders at first admission. The predicted cumulative incidence of drug related death was significantly higher in opiate and barbiturate abusers over the observed period of 37 years, while stimulant abuse did not have any impact. Alcohol contributed to non drug related death.

Vulnerable adolescent participants' experience in surveys on sexuality and sexual abuse: ethical aspects

OBJECTIVE

The aim of this research was to study the discomfort experienced by adolescents when answering questions in a survey about sexuality and sexual abuse and to investigate factors that may determine possible experience of discomfort. The research focused particularly on vulnerable adolescents-sexually abused and sexually inexperienced.

METHOD

Adolescents in their final year of high school in Estonia (n=1,334) and Sweden (n=3,401) who had completed a survey about experiences of sexuality and sexual abuse answered additional questions about experiences of discomfort related to the survey questions.

RESULTS

A majority of the participants did not feel discomfort when completing the survey. This was also the case for the two vulnerable groups. Experience of penetrating sexual abuse, sexual inexperience, mental health problems, rape myth acceptance, gender, immigrant background, and country were included in a structural equation model. Experience of penetrating sexual abuse was not significantly related to discomfort in the final model, while sexual inexperience was associated with increased discomfort (standardized coefficient .20) and rape myth acceptance was the strongest indicator of discomfort (.27). The total amount of explained variance was 17%.

CONCLUSIONS

Our data do not support the view that adolescents in general or vulnerable subgroups such as sexually abused or sexually inexperienced adolescents experience discomfort when answering a survey about sexuality and sexual abuse. As discomfort ratings were not highly related to any of the predictors further research is needed that includes other factors. It is important to follow existing ethical guidelines since there may always be some individuals who feel discomfort.

The stability of alexithymia during work in a high-stress environment: a prospective study of Swedish peacekeepers serving in Kosovo

We applied a prospective design to reinvestigate the issue whether the sub-domains of alexithymia could be considered stable traits or distress-related states. Assessments of alexithymia and subjective distress were conducted before deployment to Kosovo in a sample of male peacekeepers. A second assessment was conducted approximately six months later during the final phase of service. The results showed evidence of moderate to high relative stability in all alexithymic sub-domains. It was also found that a relative change in subjective distress predicted a relative change in difficulty identifying feelings and difficulty describing feelings but not in externally oriented thinking. We suggest therefore that the alexithymic sub-domains could be considered relatively stable traits but that the level of difficulty identifying and describing feeling varies with the level of subjective distress.

The Role of Perceived Control for the Perception of Health by Patients with Persistent Mental Illness

Perceived control has been found to be of significance for patients with psychiatric disorders and may be regarded as an aspect of empowerment. Moreover, a sense of control has been identified as important for occupational performance, both in empirical research and in occupational therapy theory. This study aimed at investigating factors that might be of importance for perceived control: sociodemographic, clinical, and well-being variables. Another aim was to investigate whether perceived control served as a mediator between clinical variables, in terms of psychopathology, and well-being variables, in terms of perceived health. Sociodemographic data were collected from 177 subjects, most of them with psychosis diagnoses. They were also assessed regarding perceived control (locus of control and self-mastery) and different aspects of health and well-being. The findings showed that both clinical and well-being variables were consistently related to both aspects of perceived control. Moreover, the roles of self-mastery and locus of control as mediators of perceived health were identified. The results also identified some important sociodemographic factors that might promote a sense of control and empowerment, mainly educational level and friends. This study provided detailed knowledge of the role of perceived control for well-being among people with mental disorders. Strategies for how occupational therapists may promote a sense of control in this group are discussed.

Baseline verbal fluency performance as predictor of state anxiety during a live hand-grenade throwing exercise - A prospective study of Swedish military conscripts

Background

We investigated whether individual differences in baseline executive control capacity could predict state anxiety during a potentially life-threatening situation.

Methods

19 Swedish military conscripts were assessed during two measurement occasions. During a baseline measurement, data regarding performance on a letter fluency task and state anxiety were assessed. During a second measurement, performed immediately prior to participation in a live hand-grenade throwing exercise, data regarding state anxiety was assessed. All participants were male, right-handed and had fulfilled 12 years of education.

Results

The level of state anxiety was significantly increased between the two measurement occasions (p < .01). Both the number of words produced (β = -.37; p < .05) and the number of perseveration made (β = .43; p < .05) on the verbal fluency task predicted, while controlling for state anxiety at baseline, the level of experienced state anxiety during the threatening situation.

Conclusion

Although more research is needed the present finding suggests that individual differences in executive control capacity might be related to emotion regulation ability during acute stressor exposure.

Protein S100B after cardiac surgery: an indicator of long-term anxiety?

OBJECTIVES

The aim of the study was to assess long-term state and trait anxiety in cardiac surgical risk patients.

DESIGN

Thirty two patients with serum S100B>0.3 microg/l 48 hours after cardiac surgery with cardiopulmonary bypass were matched according to age, gender, type, date and length of surgery with 35 operated patients without elevated S100B. They completed Spielberger's Anxiety Inventory (STAI).

RESULTS

Patients with elevated S100B reported more state anxiety and trait anxiety. S100B was an independent predictor of both state and trait anxiety when controlling for perioperative variables.

CONCLUSIONS

Patients with elevated S100B reported more anxiety 3-6 years after cardiac surgery. A postoperative blood sample can identify risk patients and facilitate appropriate follow-up.

Adverse drug reaction reporting by nurses in Sweden

AIM

To investigate whether nurses could be a useful tool for improving the reporting rate of adverse drug reactions (ADRs). Furthermore, we wanted to study how physicians working at the study departments would respond to nurses as reporters of ADRs and if the reporting from the nurses affected the reporting rate from the physicians.

METHOD

Three departments of internal medicine and one unit for orthopaedics were selected for the study. Nurses with special drug responsibilities were invited to participate. At the start of the study period, the nurses received an introduction with background, objective, method and other practical issues concerning the study. After this, an education programme about ADR reporting, definitions, and ADR classification according to mechanism and organ system was given. To study their knowledge about and attitude towards ADRs, a questionnaire was handed out to the nurses. A questionnaire was also handed out to all physicians at the participating departments in order to investigate their attitude towards nurses as reporters of ADRs.

RESULTS

Fifty-four nurses participated in the study. During the study period, a total number of 23 reports with 39 ADRs were sent to the regional centres by the nurses. Seventeen (74%) of the reports were assessed as serious. Eight of the 39 ADRs were unlabelled and all reports were considered appropriate. The reporting rate from the physicians during the study period was similar to the previous year, indicating that the nurses contributed with additional reports. At the end of the study, the nurses thought that they had enough knowledge to report ADRs. Sixty-eight percent of the physicians did not object to nurses being included as reporters of suspected ADRs.

CONCLUSION

Adverse drug reaction reporting by nurses could improve the overall safety of drugs.

Investigating a Computerised Test of the Stroop Effect Extended by Inclusion of a Third, More Difficult Task

A validation study of a computerised test recently developed involving the Stroop effect, extended here by inclusion of a third, more difficult test series, is presented. Three groups of men belonging to the Swedish armed forces and adjudged to differ in their qualifications (20, 32, and 19 men of levels 1, 2, and 3, respectively) and a fourth group of 18 men convicted of serious crimes of violence were given this test, termed the Stress Strategy Test. Discriminant analysis of the test's 12 variables (four for each of the three test series) yielded a discriminant power of 65% for the total group, highest for the level 1 group (80%) and for the nonmilitary group (72%), results substantially better than obtained for the original version of the test with use of similar subject groups.

Higher-Order Factors in a Five-Factor Personality Inventory and its Relation to Social Desirability

Abstract. This paper compared two higher-order factor models using a 100-item, five-factor personality inventory originating from the IPIP database. The sample consisted of 2,019 subjects tested on the Internet. The two models were compared using confirmatory factor analysis. The two-factor model showed a similar fit to the data. The criteria for parsimony favored a hierarchical model with one higher-order factor at the top and five personality factors beneath. The single higher-order factor was found to be related to social desirability in a subsample of 196 subjects.
