Anger, personality traits and psychopathological symptoms in subjects exposed to negative interpersonal actions in workplaces: an observational study in a large sample attending a Center for Occupational Stress

OBJECTIVE

The association between adverse working conditions and mental disorders is well established. In addition to psychopathological symptoms, this study aimed at investigating anger and personality traits in a clinical sample of subjects referring negative interpersonal experiences in workplaces.

METHODS

1676 workers attending a Centre for Occupational Stress in Milan (from 2014 to 2016) were administered an assessment protocol including SCL-90 for general psychopathology, STAXI for anger intensity and expression, and MMPI-2 for personality traits. A qualitative checklist was used to collect negative experiences in workplaces.

RESULTS

Patients reported they were exposed to "threats to the task or the professional career" more than to "attacks to the person". Over 80% scored above the cutoff in all the subscales of the SCL-90, with highest scores in Depression, Obsessive-Compulsive Disorder, Anxiety, Somatization and Paranoia. 60% scored above the 90th percentile in the AX/in subscale, showing intense anger feelings that they mostly suppress. Abnormal elevations at the MMPI scales of Hypochondria, Depression, Hysteria, and Paranoia were found in over 50% of the sample. Women reported higher psychological difficulties and internalized anger than men. Anger towards objects and people, instead, was more common in males. No differences were observed by work sector or employment status.

CONCLUSIONS

In addition to severe psychological difficulties, individuals reporting negative interpersonal experiences in workplaces have high levels of internalized anger and a distinctive profile of personality traits. While a deeper investigation is needed, anger expression should be considered in future treatment programs.

Disorder-specific and shared neurophysiological impairments of attention and inhibition in women with attention-deficit/hyperactivity disorder and women with bipolar disorder

BACKGROUND

In adults, attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder (BD) have certain overlapping symptoms, which can lead to uncertainty regarding the boundaries of the two disorders. Despite evidence of cognitive impairments in both disorders separately, such as in attentional and inhibitory processes, data on direct comparisons across ADHD and BD on cognitive-neurophysiological measures are as yet limited.

METHOD

We directly compared cognitive performance and event-related potential measures from a cued continuous performance test in 20 women with ADHD, 20 women with BD (currently euthymic) and 20 control women.

RESULTS

The NoGo-N2 was attenuated in women with BD, reflecting reduced conflict monitoring, compared with women with ADHD and controls (both p < 0.05). Both ADHD and BD groups showed a reduced NoGo-P3, reflecting inhibitory control, compared with controls (both p < 0.05). In addition, the contingent negative variation was significantly reduced in the ADHD group (p = 0.05), with a trend in the BD group (p = 0.07), compared with controls.

CONCLUSIONS

These findings indicate potential disorder-specific (conflict monitoring) and overlapping (inhibitory control, and potentially response preparation) neurophysiological impairments in women with ADHD and women with BD. The identified neurophysiological parameters further our understanding of neurophysiological impairments in women with ADHD and BD, and are candidate biomarkers that may aid in the identification of the diagnostic boundaries of the two disorders.
