Background: We currently define dysphoria as a complex and disorganized emotional state with proteiform phenomenology,
characterized by a multitude of symptoms. Among them prevail irritability, discontent, interpersonal resentment and surrender.
Dysphoria, in line with the most recent Interpersonal Dysphoria Model, could represent a “psychopathological organizer” of the
Borderline Personality Disorder. We would like to extend this theoretical concept to other psychiatric disorders in order to consider
dysphoria as a possible psychopathological nucleus, a syndrome on its own. This syndromic vision may open up the possibility of
new paths both in the differential diagnosis and in the therapeutic approach to the various disorders.
Aims: The goal of this paper is to understand if the dimensional spectrum that composes dysphoria differs from the different
psychiatric disorders. Specifically, we would like to assess if the phenomenological expression of dysphoria differs in patients with
Borderline Personality Disorder (BPD), Mixed State Bipolar Disorder (BDM) and Major Depressive Disorder (MDD) through an
observational comparative study.
Subjects and methods: In this study, 30 adult patients, males and females between the ages of 18 and 65, were enrolled from the
Psychiatric Service of the Santa Maria della Misericordia Hospital in Perugia (PG), Italy, from January 1st to June 30th, 2018. The
aim was to form 3 groups each one composed of 10 individuals affected respectively with Borderline Personality Disorder (BPD),
with Bipolar Disorder, Mixed State (BPM) and Major Depression Disorder (MDD). After a preliminary assessment to exclude
organic and psychiatric comorbidity, we administered them the Neapen Dysphoria Scale – Italian Version (NDS-I), a specific
dimensional test for dysphoria. Starting from the dataset, with the aid of the statistical program SPSS 20, we have obtained graphs
showing the comparison between disorders groups selected and NDS-I total score and subscales (irritability, discontent,
interpersonal resentment, surrender). Finally, a comparison was made, taking two groups at a time, between the means of single
groups for total scores and for single subscales considered into the NDS-I test. We made it using the Mann-Whitney U test, a
nonparametric test with 2 independent samples, by setting a significance level =0.05.
Conclusions: This study, through a transnosographic-dimensional approach, allowed us to explore dysphoria and its expressions
in different psychopathological groups, despite analyzing a small sample. Differences between means of values obtained through
NDS-I subscales were statistically significant in patients with BPD, BDM and MDD (p<0.05). Among the latter, the group of BPD
patients has greater pervasiveness and severity of dysphoria symptoms
