GSR profiles were examined for the various types of Mood Disorder and their association with comorbidity, suicidality and predispositions. This review examined studies with emotional and non-emotional stimuli whilst aiming to identify a Mood Disorder GSR profile by comparisons with healthy controls and other psychological or physical disorders. A systematic search for relevant literature was conducted using PsychINFO, CINAHL and MEDLINE databases. Studies using emotional stimuli to measure GSR in mood disorder patients were included. Some studies did not use emotional stimuli, however were included as GSR measures were conducted separately from stimuli presentation. A greater proportion of studies reported results in support of a specific GSR profile for mood disorders as well as indicating GSR variation depending on type of disorder. Distinguishing the GSR profile from other psycho...

La informacion clinica y demografica se recogio de 27 participantes de TB eutimicos o residualmente deprimidos. Setenta y uno por ciento de la muestra reporto algun grado de deterioro en el funcionamiento psicosocial. Tanto la depresion residual y problemas con la regulacion de las emociones fueron identificados como predictores significativos de mal funcionamiento psicosocial. Ademas de la depresion residual, los resultados del presente estudio introducen una variable de disregulacion emocional para dar cuenta del pobre funcionamiento psicosocial en las poblaciones de TB. La mejora de las estrategias de regulacion emocional, en particular, la concentracion y la realizacion de tareas durante los estados emocionales negativos podrian tener consecuencias importantes para mejorar el funcionamiento psicosocia...

It is an important transdiagnostic risk factor for psychosomatic disorders and other types of emotion-based psychopathologies, and can reduce the efficacy of some treatment approaches. Alexithymia assessments are therefore important in psychiatric and research settings. The Perth Alexithymia Questionnaire (PAQ) was recently developed to enable more comprehensive alexithymia assessments, however, its psychometric properties need further examination and it is so far only available in English. In this study, we sought to address this by translating the PAQ into Spanish and testing its psychometric properties in an adult sample from Chile (N = 370). Confirmatory factor analyses found the PAQ to have a theoretically congruent factor structure, supporting the contemporary status of alexithymia as a multifaceted construct and the PAQ&...

In this article, we examine the psychometric properties of the PERS subscale and composite scores in an adult community sample (N = 428), and develop an 18-item short form of the measure (PERS-S). The PERS and PERS-S are designed to assess the typical ease of activation, intensity, and duration of one's emotional responses, and do so for positive and negative emotions separately. Our confirmatory factor analyses supported that the PERS and PERS-S both had the same theoretically congruent factor structure, and that all subscale and composite scores displayed high internal consistency reliability. Correlations with scores from established measures of psychopathology and emotion regulation also supported the validity of PERS and PERS-S scores. Our data therefore suggest that the PERS-S subscale and composite scores retain the psychometric strengths of their longer P...

The aim of the present systematic review was to (i) critically review all available evidence on Mindfulness Based Cognitive Therapy (MBCT) as a form of intervention for BD; (ii) discuss clinical implications of MBCT in treating patients with BD; and (iii) provide a direction for future research. The review presents findings from 13 studies (N = 429) that fulfilled the following selection criteria: (i) included BD patients; (ii) presented results separately for BD patients and control groups (where a control group was available); (iii) implemented MBCT intervention; (iv) were published in English; (v) were published in a peer reviewed journal; and (vi) reported results for adult participants. Although derived from a relatively small number of studies, results from the present rev...

Neurocognitive impairment has been identified as a contributing factor towards unfavourable psychosocial functioning within this population. The objective of this review was to investigate the association between neurocognitive impairment and occupational functioning in BD. A literature review of English-language journal articles from January 1990 to November 2013 was undertaken utilising the PsychINFO, Scopus and Web of Knowledge databases. Studies that made specific reference to occupational outcomes were included, and those that reported on global psychosocial measures were excluded. Majority of the papers reviewed (20 out of 23) identified an association between neurocognitive impairment (particularly in executive functioning, verbal learning and memory, processing speed and attention) and occupational functioning. Several methodological issues were identified. There was a discrep...

To evaluate the psychometric properties of the Toronto Alexithymia Scale (TAS-20) in an Australian psychiatric and community sample; 2. To investigate the differences in the pattern of prevalence between these two samples; and 3. To investigate whether the differences could be accounted for by demographic variables and/or psychological distress. Participants consisted of 166 psychiatric patients and 216 community participants. Results suggested that the overall TAS-20 scale demonstrated good internal reliability for the psychiatric sample (α = .80) but several items of the scale had correlations below .3. Internal reliability of the three factors that compose the TAS-20 differed greatly. The internal reliability for Factor 1 (Difficulties identifying emotions) was good (α = .88), but was poor for Factor 2 (Difficulties explaining emotions) (α = .50) and unacceptable for Factor 3 (Externally oriented thinking ) (α = .28). Comparable results were observed in the community sample. Regarding the prevalence of Alexithymia, results indicated more than 75% of the psychiatric sample had Alexithymia symptomatology. Furthermore, results suggested non-significant interaction effects of gender on Alexithymia between the psychiatric and community samples. However, some interactions were observed when comparisons were conducted with the factors of the TAS-20 separately. In the psychiatric sample, females had more difficulties identifying their emotions, whereas in the community sample the reversed was observed. The level of education or employment showed non-significant interaction effects on Alexithymia between the group samples. Predictably, the psychiatric participants had significantly greater psychological distress (as assessed by the Depression Anxiety Stress Scale [DASS]) compared to the community participants. To determine whether the DASS had an impact on Alexithymia, bivariate correlations were calculated between DASS and TAS scores. A significant medium positive association between DASS and TAS-20 scores for both psychiatric and community samples was observed. The implications of these findings for both the conceptualisation of Alexithymia and its role in psychiatric presentations and therapy are discussed.

To date however relatively few randomised control trial (RCT) studies have investigated the effect of mindfulness training on attentional skills in novice practitioners. This study examined the effect of daily mindfulness practice on changes in attention skills; alerting, orienting and executive control in novice practitioners. Forty six university students from Perth, Western Australia were randomly assigned to one of two groups (mindfulness or waitlist control). Baseline analyses of psychological wellbeing indicated that the two groups initially were comparable in this domain. Pre- and post-test assessments using the Attention Network Test (ANT) were conducted to measure attention skills. Repeated measures ANOVA were used to examine the effect of intervention. Significant improvement in orienting and executive control skills following the mindfulness intervention was noted, however, no changes in alerting attentional skills were detected. Mindfulness practice impacted on the fundamental processes of the selective (orienting) and executive attention (executive control) networks which may in turn have additional beneficial effects in a variety of domains and situations. These findings add to existing literature that supports the positive and beneficial effect of regular mindfulness practice for the enhancement of attentional skills and its potential application to clinical populations.

JD, a 30 year old male whose recurrent craniopharyngioma had 2 years earlier been treated with two operations and conventional radiotherapy. JD was assessed (using standardized clinical tests) before and after a course of stereotactic radiotherapy. Prior to stereotactic radiotherapy (and 2 years after microsurgery and conventional radiotherapy) JD's IQ was intact, but considerable impairments were present in executive functioning, memory, theory of mind and processing speed. Fifteen months after stereotactic radiotherapy, all neuropsychological domains remained largely static or improved, supporting the utility of this treatment option in the neuropsychological domain. However, deficits in executive...
