[Ab] Resumo:The aim of this study was the validation and analysis of the psychometric properties of a Spanish translation of the ORTO-15 questionnaire; an instrument designed to assess orthorexia nervosa behavior. Four hundred and fifty-four Spanish university students (65% women) aged between 18 and 51 years (M = 21.48 ± 0.31) completed the Spanish version of ORTO-15 and the Eating Disorders Inventory-2 (EDI-2). The Principal Component Analysis suggested a three-factor structure for the abbreviated 11-item version of the instrument. The internal consistency of the measurement was adequate (Cronbach's alpha = 0.80). The proposed test demonstrated a good predictive capacity at a threshold value of <25 (efficiency 84%, sensitivity 75% and specificity 84%). Our results support the psychometric properties of the proposed Spanish shortened-version of the ORTO-15 as being a reliable tool for assessing orthorexia nervosa. Its use is expected to greatly contribute to a better understanding of the impact of this disorder in Spain.

[Ti] Título:The centrality of affective instability and identity in Borderline Personality Disorder: Evidence from network analysis.

[Ab] Resumo:We argue that the series of traits characterizing Borderline Personality Disorder samples do not weigh equally. In this regard, we believe that network approaches employed recently in Personality and Psychopathology research to provide information about the differential relationships among symptoms would be useful to test our claim. To our knowledge, this approach has never been applied to personality disorders. We applied network analysis to the nine Borderline Personality Disorder traits to explore their relationships in two samples drawn from university students and clinical populations (N = 1317 and N = 96, respectively). We used the Fused Graphical Lasso, a technique that allows estimating networks from different populations separately while considering their similarities and differences. Moreover, we examined centrality indices to determine the relative importance of each symptom in each network. The general structure of the two networks was very similar in the two samples, although some differences were detected. Results indicate the centrality of mainly affective instability, identity, and effort to avoid abandonment aspects in Borderline Personality Disorder. Results are consistent with the new DSM Alternative Model for Personality Disorders. We discuss them in terms of implications for therapy.

[Ab] Resumo:A striking observation in obsessive-compulsive disorder is that patients know that their obsessions and compulsions are excessive, but their symptoms nevertheless persist. Drawing on computational models from basic neuroscience, Vaghi and colleagues (2017) suggest a quantitative account of this clinical finding.

[Ti] Título:Characterising the latent structure and organisation of self-reported thoughts, feelings and behaviours in adolescents and young adults.

[Ab] Resumo:Little is known about the underlying relationships between self-reported mental health items measuring both positive and negative emotional and behavioural symptoms at the population level in young people. Improved measurement of the full range of mental well-being and mental illness may aid in understanding the aetiological substrates underlying the development of both mental wellness as well as specific psychiatric diagnoses. A general population sample aged 14 to 24 years completed self-report questionnaires on anxiety, depression, psychotic-like symptoms, obsessionality and well-being. Exploratory and confirmatory factor models for categorical data and latent profile analyses were used to evaluate the structure of both mental wellness and illness items. First order, second order and bifactor structures were evaluated on 118 self-reported items obtained from 2228 participants. A bifactor solution was the best fitting latent variable model with one general latent factor termed 'distress' and five 'distress independent' specific factors defined as self-confidence, antisocial behaviour, worry, aberrant thinking, and mood. Next, six distinct subgroups were derived from a person-centred latent profile analysis of the factor scores. Finally, concurrent validity was assessed using information on hazardous behaviours (alcohol use, substance misuse, self-harm) and treatment for mental ill health: both discriminated between the latent traits and latent profile subgroups. The findings suggest a complex, multidimensional mental health structure in the youth population rather than the previously assumed first or second order factor structure. Additionally, the analysis revealed a low hazardous behaviour/low mental illness risk subgroup not previously described. Population sub-groups show greater validity over single variable factors in revealing mental illness risks. In conclusion, our findings indicate that the structure of self reported mental health is multidimensional in nature and uniquely finds improved prediction to mental illness risk within person-centred subgroups derived from the multidimensional latent traits.

[Ti] Título:Self-control predicts attentional bias assessed by online shopping-related Stroop in high online shopping addiction tendency college students.

[Ab] Resumo:OBJECTIVE: The aim of this study was to examine the relationships of personality types (i.e., self-control, BAS/BIS) and online shopping addiction (OSA) behavior and to investigate whether high-OSA tendency individuals display attentional biases toward online shopping-related (OS-related) stimuli as well as the links between attentional bias and personality types. METHOD: The study included 98 college students divided into three groups (i.e., high-, medium- and low-OSA) according to their OSA behavior. The personality types (i.e., self-control, BAS/BIS) and OSA behavior were investigated by questionnaires. The attentional bias was evaluated by the OS-related Stroop and dot-probe task (DPT) paradigms. RESULTS: OSA was positively predicted by time spent on online shopping per day and average consumption for online shopping monthly, and negatively by self-control. High-OSA individuals displayed significant attentional biases toward OS-related stimuli in the Stroop, but not DPT paradigm. Moreover, the attentional bias toward OSA-related stimuli in high-OSA individuals was negatively correlated with self-control. CONCLUSION: These findings demonstrated the critical role of self-control in OSA behavior and attentional bias to OS-related stimuli in high-OSA individuals, indicating that more importance should be attached to self-control for the clinical intervention of online shopping addiction in future studies.

[Ti] Título:The effect of trauma on the severity of obsessive-compulsive spectrum symptoms: A meta-analysis.

[Ab] Resumo:It is important to consider trauma-related sequelae in the etiology and maintenance of psychopathology, namely understudied disorders such as those belonging to the Obsessive-Compulsive Spectrum (OCS). This meta-analysis examined the association between past trauma exposure and current severity of OCS disorder symptoms. A systematic literature search was conducted with 24 (N=4557) articles meeting inclusion criteria. A significant overall effect size was obtained (r=0.20), indicating that exposure to past trauma is associated with a higher severity of OCS symptoms, with a stronger association for females (ß=0.01, p<.001) but not varying as a function of relationship status. Four types of interpersonal trauma (violence, emotional abuse, sexual abuse, and neglect) were associated with OCS symptom severity (r=0.19 -0.24) and past trauma was significantly associated with more severe compulsions (r=0.17), but not obsessions. Results suggest an important link between multiple types of past trauma exposure and OCS symptoms.

[Ab] Resumo:The aim of this study was to evaluate the prevalence of comorbid obsessive compulsive symptoms/disorder and its impact on outcome among patients with schizophrenia. 181 patients with schizophrenia were evaluated on Yale-Brown Obsessive-Compulsive Symptom Checklist, Yale-Brown Obsessive-Compulsive Scale, Calgary Depression Scale for Schizophrenia, Positive and Negative Symptom Scale, Social Occupational Functioning Scale, Global Assessment of Functioning Scale and Indian Disability Evaluation and Assessment Scale. Slightly more than one-fourth of patients fulfilled the diagnosis of current (28.2%) and lifetime (29.8%) diagnosis of obsessive compulsive disorder. On Yale Brown Obsessive Compulsive Symptom Checklist, the most common lifetime obsessions were those of contamination (25.4%), followed by obsessions of need for symmetry or exactness (11.6%). The most common compulsions were those of cleaning/washing (27.1%), followed by those of checking (24.3%). Presence of obsessive compulsive symptoms was associated with younger age of onset, higher prevalence of comorbid depression, and current suicidal ideations. Thus, it can be concluded that a significant proportion of patients with schizophrenia have obsessive compulsive symptoms/disorder. Clinicians managing patients of schizophrenia should evaluate the patients thoroughly for presence of comorbid obsessive compulsive symptoms/disorder and must take the same into account while managing the patients.

[Ti] Título:Anodal tDCS over the right dorsolateral prefrontal cortex modulates cognitive processing of emotional information as a function of trait rumination in healthy volunteers.

[La] Idioma:eng
[Ab] Resumo:Healthy individuals reporting higher (as compared to lower) levels of trait rumination recruit more neural activity in dorso-cortical regions (mostly in the right hemisphere) when inhibiting negative information, possibly to compensate their difficulty to disengage from it. In the present study, we investigated whether these latter neural correlates are causally implicated in cognitive control in these individuals. We administered the Cued Emotional Control Task, a measure of cognitive control indexed by cognitive costs for inhibiting versus providing a habitual response for emotional information, in thirty-five healthy volunteers reporting a broad range of trait rumination levels. Participants completed the task after receiving both real and sham-placebo (counterbalanced order) anodal transcranial Direct Current Stimulation (tDCS) over the right dorsolateral prefrontal cortex (DLPFC). Results reveal that the tDCS induced effects on cognitive costs for emotional information were associated with individual differences in trait rumination: the higher the trait rumination level, the less cognitive costs following real neuromodulation of the right DLPFC. Interestingly, these effects were observed for both positive and negative stimuli, and not only negative information as hypothesized. Overall, the data suggest that the right DLPFC is causally involved in the alteration of cognitive control in healthy individuals who tend to ruminate, possibly by helping them to disengage from emotional material.

[Ti] Título:The Termination of Checking and the Role of Just Right Feelings: A Study of Obsessional Checkers Compared with Anxious and Non-clinical Controls.

[Ab] Resumo:BACKGROUND: Repeated checking in OCD can be understood from a cognitive perspective as the motivated need to achieve certainty about the outcome of a potentially risky action, leading to the application of Elevated Evidence Requirements (EER) and overuse of subjective criteria. METHOD: Twenty-four obsessional checkers, 22 anxious controls, and 26 non-clinical controls were interviewed about and rated recent episodes where they felt (a) they needed to check and (b) checked mainly out of habit (i.e. not obsessionally). RESULTS: Both subjective and objective criteria were rated as significantly more important in obsessional checkers than in controls; obsessional checkers also used more criteria overall for the termination of the check, and rated more criteria as "extremely important" than the control groups. The termination of the check was rated as more effortful for obsessional checkers than for the comparison groups. Analysis of the interview data was consistent with the ratings. Feelings of "rightness" were associated with the termination of a check for obsessional checkers but not for controls. CONCLUSION: Results were consistent with the proposal that the use of "just right feelings" to terminate checking are related to EER.
