Interpersonal problems and personality traits: The relation between IIP-64C and NEO-FFI

This article re-examines the relation between The Inventory of Interpersonal Problems (IIP-64C) and the Five-Factor Model of personality, using both normative and statistic ipsative scores in the partitioning of the IIP-64C item set. A non-clinical sample (n = 132) completed the NEO-FFI personality inventory and the IIP-64C. In accordance with previous studies, Agreeableness and Extraversion were linked with IIP-64C, regardless of type of partitioning of the IIP-64C item set. Neuroticism had a strong association with interpersonal problems based on normative scores, but statistic ipsation removed this association. While the normative IIP-64C scores did not confirm the structural properties of the Circumplex model, the ipsatized scores did. In conclusion, the use of statistical ipsation of the IIP-64C could be a useful addition to traditional personality assessment procedures.

Personality traits, gender differences and symptoms of anhedonia: What does the Hospital Anxiety and Depression Scale (HADS) measure in nonclinical settings?

In healthy populations men report more depressive symptoms than women when depression is measured by the Hospital Anxiety and Depression Scale (HADS). This study aims to investigate the role of neuroticism and extroversion in symptom reporting by men and women and whether anhedonia can explain these reversed gender differences in depression observed when using HADS. HADS, Positive and Negative Affect Schedule (PANAS) and NEO Five Factor Inventory (NEO FFI) were administered twice to a sample of university students. Number of subjects at T1 was 372 and 160 at T2, measured two months apart. Men had a higher average score on depressive symptoms measured by HADS-D compared to women (p = 0.029). Women scored higher than men on HADS-A (p = 0.012), neuroticism (p < 0.001) and PANAS-negative affect (p < 0.029). No significant gender differences were observed in extroversion and positive affect. Test-retest stabilities on HADS-A and HADS-D were high. Neuroticism predicted HADS-A at Time 2. Gender, extroversion, and neuroticism predicted HADS-D at Time 2. The anhedonic content in HADS may be a plausible explanation of reversed gender differences in the HADS depression scale. HADS-D represents a specific anhedonic subtype of depression where symptom reporting reflects dispositional tendencies related specifically to extroversion.

Symptoms of depression and anxiety before and after myocardial infarction: The HUNT 2 and HUNT 3 study

The long-term effect of having a myocardial infarction (MI) and to what extent post-MI anxiety and depression can be attributed to pre-MI anxiety and depression are not known. Anxiety as an independent risk factor for the onset of MI is not clear and studies treating anxiety and depression as continuous variables are lacking. Baseline data in this prospective study were obtained from the Health Study of Nord-Trøndelag County (HUNT 2). Anxiety and depression were measured with the Hospital Anxiety and Depression Scale (HADS) at HUNT 2. Age, gender, waist circumference, hypertension, total cholesterol, diabetes, and years of daily smoking were included as control variables. In the sample of 28,859 participants, 770 MI were reported in the follow-up study 5–8 years later (HUNT 3). The level of depressive symptoms at HUNT 2 was a significant and independent predictor of MI at HUNT 3, while symptoms of anxiety were not. Level of anxiety and depression at HUNT 3 was best predicted by baseline anxiety and depression. Having an MI had only a marginal effect on the levels of anxiety and depressive symptoms at HUNT 3. In the MI group, time since MI was not a significant predictor of anxiety and depression.

The Personality of Homeopaths: A Cross-Sectional Survey of the Personality Profiles of Homeopaths Compared to a Norm Sample

OBJECTIVES The Revised NEO Personality Inventory (NEO-PI-R) was used to describe the personality profiles of homeopaths in Norway. It was hypothesized that the homeopaths would score higher than the norm sample on Openness, Agreeableness, and Conscientiousness. DESIGN The NEO-PI-R describes personality scores on five traits; Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness. A cross-sectional survey of 128 (39%) members of the Norwegian association for homeopaths was compared with the Norwegian population norm sample. RESULTS Compared to the norm population score with a mean of 50, the homeopaths scored significantly higher on the personality traits Openness (54.7) and Agreeableness (58.0). Significant, but small differences were also observed with a higher score on Conscientiousness (52.3) and a lower score on Extraversion (48.3). There were no significant differences on Neuroticism (49.7). CONCLUSIONS People who work as homeopaths can be described as open to new and different ideas, and as caring, understanding, and altruistic persons. Therefore, there is reason to believe that these dispositions are central in choosing homeopathy as an occupation. Further research should investigate whether personality traits are associated with important occupational areas such as job satisfaction, occupational stability, or income.

Dispositional factors and work mastery among shift workers.

ABSTRACT The aim of the present study was to investigate how broad personality dimensions and dispositional resistance to change are associated with mastery of work among shift workers. A total of 285 shift workers employed in rotating shifts with morning, evening and night work and night shift schedules in a municipality in Norway completed electronic questionnaires. The findings suggest that the broad personality dimensions neuroticism and conscientiousness were significant predictors of perceived work mastery among shift workers in this sample, whereas the narrow trait dispositional resistance to change was not.

Anhedonic depression, history of depression, and anxiety as gender-specific risk factors of myocardial infarction in healthy men and women: The HUNT study

This prospective study examines gender-specific psychological risk factors of myocardial infarction. Out of 41,248 participants free of coronary heart disease at baseline, 822 cases of myocardial infarction were identified in the Nord-Trøndelag Health Study or the mortality register. The participants completed the Hospital Anxiety and Depression Scale. Cholesterol, blood pressure, and waist–hip ratio were measured by medical staff. Smoking, diabetes, non-fatal myocardial infarction, and history of depressive episode were self-reported. Anhedonic depression (Hospital Anxiety and Depression Scale-D ≥8) was a significant predictor of myocardial infarction in women but not in men. Gender difference in risk estimate based on Hospital Anxiety and Depression Scale-D was significant (p < .01). History of depressive episode was a significant predictor of myocardial infarction in men. Symptoms of anxiety (Hospital Anxiety and Depression Scale-A ≥8) reduced the risk of having a myocardial infarction.

Psychometric Properties of the Snaith–Hamilton Pleasure Scale and a Facet-Level Analysis of the Relationship Between Anhedonia and Extraversion in a Nonclinical Sample

The aim of this study is to investigate the psychometric properties of the Snaith–Hamilton Pleasure Scale (SHAPS) and look at facets of extraversion as predictors of anhedonia. SHAPS is hypothesized to be multidimensional, stable over time in a nonclinical sample, and related to extraversion on both dimension and facet level. Data collection was conducted at baseline (N = 362) and at a 10-week follow-up (N = 94). The structural properties of SHAPS were analyzed using principal component analysis and confirmatory factor analysis. Multiple regression explored facets of extraversion as predictors of anhedonia. The results show that SHAPS is stable across time (r = .71, p < .001), with high internal consistency (α = .89). In the principal component analysis, a two-factor model emerged (Social and Physical anhedonia). The confirmatory factor analysis indicated that the two-factor model consisting of Physical anhedonia (α = .81) and Social anhedonia (α = .87) had a better fit than the one-factor model. Higher scores on Gregariousness and Positive emotions at baseline predicted higher scores on the SHAPS total and Social and Physical anhedonia (p < .05). Lower scores on Assertiveness predicted higher scores on Social anhedonia (p < .05). These results support the view of anhedonia as a multidimensional concept that should be regarded as a trait, rather than a state or mere bypassing symptom. The relationship between anhedonia and extroversion is best understood by applying a multidimensional approach to anhedonia and by focusing on the facet level of extroversion.

The Strives, Struggles, and Successes of Women Diagnosed With ADHD as Adults:

The objective of the study was to aid an understanding of women’s experiences of living with attention deficit hyperactivity disorder (ADHD), with special consideration of the role of stigma and gender-specific issues. Semistructured in-depth interviews were conducted with five women aged 32 to 50 years, all diagnosed with ADHD as adults. The interviews were analyzed in accordance with thematic analysis. The data analyses were centered around five core themes: (a) from unidentified childhood ADHD to adult diagnosis, (b) present main symptoms and challenges, (c) conflict between ADHD symptoms and gender norms and expectations, (d) stigma of ADHD: “People think it’s a fake disease,” and (e) managing ADHD symptoms and identifying strengths. Despite their difficulties, all participants are highly educated and employed, and differ from common portrayals of individuals with ADHD as observably hyperactive, disruptive, or globally impaired. The participants are reluctant about disclosure of their diagnosis, due to fear of negative judgment and lack of understanding from others. The findings highlight the importance of recognizing and targeting ADHD as a serious disorder that yields continuing, and even increasing, impairment in multiple areas into adulthood. Gender-specific issues of ADHD need to be examined further, particularly challenges associated with motherhood. Stigma and the conflict between ADHD symptoms and gender norms complicate women’s experiences of living with ADHD, and should be essential areas of focus in research, educational settings, and the media.
