“…Of note, five out of nine MOODS-SR items reflecting DSM-IV criteria for manic episode loaded on this factor (see Tables 2 and 3). This factor showed a moderate to strong correlation with all the others factors ( Table 4), suggesting that psychomotor activation is a key element for all the other aspects of mania and hypomania, in line with most of the literature (Murphy and Beigel, 1974;Double, 1990;Cassidy et al, 1998a;Cassidy et al, 2002;Hantouche et al, 2003;Benazzi, 2004;Angst et al, 2005;Koukopoulos et al, 2005;Benazzi, 2007b, Picardi et al, 2007. Notably, our data showed that increase in energy with reduced sleep (item 136) is an important feature of psychomotor activation.…”

Background-The observation that bipolar disorders frequently go unrecognized has prompted the development of screening instruments designed to improve the identification of bipolarity in clinical and non-clinical samples. Starting from a lifetime approach, researchers of the Spectrum Project developed the Mood Spectrum Self-Report (MOODS-SR) that assesses threshold-level manifestations of unipolar and bipolar mood psychopathology, but also atypical symptoms, behavioral traits and temperamental features. The aim of the present study is to examine the structure of mania/hypomania using 68 items of the MOODS-SR that explore cognitive, mood and energy/activity features associated with mania/hypomania.Methods-A data pool of 617 patients with bipolar disorders, recruited at Pittsburgh and Pisa, Italy was used for this purpose. Classical exploratory factor analysis, based on a tetrachoric matrix, was carried out on the 68 items, followed by an Item Response Theory (IRT)-based factor analytic approach.Results-Nine factors were initially identified, that include Psychomotor Activation, Creativity, Mixed Instability, Sociability/Extraversion, Spirituality/Mysticism/Psychoticism, Mixed Irritability, Inflated Self-esteem, Euphoria, Wastefulness/Recklessness, and account overall for 56.4% of the variance of items. In a subsequent IRT-based bi-factor analysis, only five of them (Psychomotor Activation, Mixed Instability, Spirituality/Mysticism/Psychoticism, Mixed Irritability, Euphoria) were retained.Conclusions-Our data confirm the central role of Psychomotor Activation in mania/ hypomania and support the definitions of pure manic (Psychomotor Activation and Euphoria) and mixed manic (Mixed Instability and Mixed Irritability) components, bearing the opportunity to identify patients with specific profiles for a better clinical and neurobiological definition.

“…Our own factor analysis of symptoms rated in 237 manic patients by the Scale for Manic States (SMS, Cassidy et al 1998aCassidy et al , 1998b, did not confirm the EG and PD factors of Beigel, Murphy, and Double (Beigel and Murphy 1971;Murphy and Beigel 1974;Double 1990). Rather, we found five distinct, orthogonal factors that represent key clinical domains of mania; namely, (1) depression and dysphoric mood; (2) psychomotor acceleration; (3) psychosis; (4) hedonic activation; and (5) irritable aggression.…”

“…It has demonstrated good psychometric properties, showing adequate reliability and validity (Poznanski et al 1984). The YMRS is an 11-item interview that assesses severity of manic symptoms and also has demonstrated good psychometric properties (Double 1990; Fristad et al 1992, 1995; Youngstrom et al 2002). Inter-rater reliability for the YMRS and CDRS-R was substantial [kappa (score ±1)=0.71 and 0.68, respectively].…”

This study examined the role of comorbid anxiety in treatment outcome for children with mood disorders (N= 165; age 8–11) participating in Multi-Family Psychoeducational Psychotherapy (MF-PEP). Assessments occurred at baseline, 6, 12, and 18 months for two randomly assigned groups: immediate treatment and 1-year wait-list. Most children (69%) had comorbid anxiety disorders. Baseline comorbid anxiety, as reported on the Children’s Interview for Psychiatric Syndromes (ChIPS), was associated with higher Children’s Depression Rating Scale- Revised (CDRS-R) scores but not Young Mania Rating Scale (YMRS) scores. Higher levels of anxiety symptoms were associated with lower Children’s Global Assessment Scale (C-GAS) scores. Participation in MF-PEP did not significantly reduce anxiety symptoms (p=0.62). However, presence of comorbid anxiety did not impede reduction in depressive (CDRS-R, p=0.74) or manic (YMRS scores, p=0.94) symptoms following MF-PEP. More baseline anxiety symptoms were associated with greater improvement in C-GAS scores post-treatment (p= 0.02). Implications are discussed.
