Systematic review of the prevalence of bipolar disorder and bipolar spectrum disorders in population-based studies

This paper describes the findings of a systematic literature review aimed at providing an overview of the lifetime prevalence of bipolar disorder and bipolar spectrum disorders in population-based studies. Databases MEDLINE, ProQuest, Psychnet, and Web of Science were browsed for papers published in English between 1999 and May 2012 using the following search string: bipolar disorders OR bipolar spectrum disorders AND prevalence OR cross-sectional OR epidemiology AND population-based OR non-clinical OR community based. The search yielded a total of 434 papers, but only those published in peer-reviewed journals and with samples aged ≥ 18 years were included, resulting in a final sample of 18 papers. Results revealed rather heterogeneous findings concerning the prevalence of bipolar disorders and bipolar spectrum disorders. Lifetime prevalence of bipolar disorder ranged from 0.1 to 7.5%, whereas lifetime prevalence of bipolar spectrum disorders ranged from 2.4 to 15.1%. Differences in the rates of bipolar disorder and bipolar spectrum disorders may be related to the consideration of subthreshold criteria upon diagnosis. Differences in the prevalence of different subtypes of the disorder are discussed in light of diagnostic criteria and instruments applied.

Randomized controlled trial of a home-visiting intervention on infant cognitive development in peri-urban South Africa.

To determine whether, in an impoverished South African community, an intervention that benefitted infant attachment also benefitted cognitive development.

Propriedades psicométricas da Cocaine Selective Severity Assessment (CSSA) em mulheres usuárias de crack

Objective This study aimed to describe the translation and adaptation of Cocaine Selective Severity Assessment (CSSA) into Brazilian Portuguese and verify the psychometric properties in a sample of crack cocaine users. Methods After the translation and adaptation steps, 125 female crack cocaine-dependent inpatients who were enrolled in an inpatient detoxification unit were evaluated. To characterize the sample and realize the analysis of concurrent validity, construct validity and predictive validity the following instruments were used: SCID-I, ASI-6, BDI-II e CCQ-B. Results The exploratory factorial analysis identified five factors and revealed appropriate levels of internal consistency, as well as the total score of the CSSA. The concurrent validity showed that CSSA was in line with instruments used in clinical practice and in researches. Further, both construct and predictive validity indicated adequate sensitivity to decline of withdrawal symptoms during the detoxification processes. Conclusions Our findings were beyond the translation and adaptation, providing the reliability and validity of CSSA regarding the evaluation of withdrawal symptoms in crack cocaine abstinence.

Psychometric Properties of the Child Posttraumatic Cognitions Inventory in a Sample of Brazilian Children

Cognitive models of trauma propose that maladaptive cognitions in children and adolescents are causally implicated in the unfolding and maintenance of posttraumatic response. The objective of this study was to evaluate the psychometric properties of the Child Posttraumatic Cognitions Inventory (CPTCI). The sample included 131 children and adolescents. The psychometric properties of the CPTCI were examined, including reliability and convergent validity. The results showed high internal consistency for both CPTCI total scale (α = .90) and its subscales (CPTCI–PC α = .88 and CPTCI–SW α = .79) and a 2-component solution explaining 37.63% of the variance of CPTCI. Convergent validity evidence was obtained through correlations with the Trauma Symptom Checklist for Children and Children’s Depression Inventory. Findings suggest that CPTCI instruments are reliable and had adequate evidence of validity.

Translation and adaptation of the Child Posttraumatic Cognitions Inventory (cPTCI) to Brazilian Portuguese

INTRODUCTIONnExperiencing a traumatic event is a risk factor for the development of mental illness, especially posttraumatic stress disorder. A childs appraisals of a traumatic event may play a prominent role in the development or maintenance of the disorder. Therefore, subjective responses should be evaluated to understand the impact of a traumatic event on a childs life. This study translated and adapted the Child Posttraumatic Cognitions Inventory (cPTCI) for use in linguistic and cultural contexts in Brazil.nnnMETHODSnThe process included translation, back-translation, language expert evaluation and expert committees evaluation.nnnRESULTSnContent validity index scores were good for all dimensions after evaluation by two judges and one reformulation. The back-translation of the final version also showed that the cPTCI items in Brazilian Portuguese maintained the same meanings of the original in English. This version was tested in a sample of the target population, and all the items were above the cut-off point (minimum = 3.6; maximum = 4.0).nnnCONCLUSIONSnThis study was successful in producing a Brazilian version of the cPTCI. Further studies are underway to examine the reliability and the factorial and concurrent validity of cPTCI subscales.

Psychometric properties of the Brazilian version of the Cognitive Emotion Regulation Questionnaire

INTRODUCTIONnThe Cognitive Emotion Regulation Questionnaire (CERQ) was developed to measure nine cognitive strategies referring to what someone thinks after the experience of threatening or stressful events. The main purpose of this study was to evaluate the validity of the Brazilian version of the CERQ.nnnMETHODSnThe adaptation process included translation, backtranslation, expert committee evaluation, and test on 30 participants from the target population. A sample of 445 university students completed the Portuguese version of the CERQ, a sociodemographic questionnaire, the Life Events Checklist (LEC-5), and the Positive and Negative Affect Schedule (PANAS) on an on-line research platform. Validity was assessed through confirmatory factor analysis of two models - a nine-factor model and a second-order model. Internal consistency was assessed through Cronbachs alpha analysis and correlations with affective variables measured by the PANAS.nnnRESULTSnThe analyses showed that the nine-factor model of the CERQ has good factorial validity and high reliability, with Cronbachs alpha values ranging between 0.71 and 0.88. The second-order model did not have a good fit to the data.nnnCONCLUSIONnThe results obtained in this study are similar to the ones found previously, indicating that the Brazilian version of the CERQ is a valid and reliable tool for assessing cognitive emotion regulation strategies, but that grouping them according to their adaptability is not recommended.

Development of the Youth Emotion Picture Set

Several facial expression image sets have been developed. Nevertheless, there is a lack of facial expression sets comprising adolescents’ images depicting all basic emotions. This study aimed to fill this gap through the development of an image database of youth facial expressions, containing pictures of six basic emotions plus neutral. Posed and spontaneous expressions were collected from 31 youths, 12 to 20 years old; 2,279 frames were obtained, and an initial screening was conducted through the exclusion of similar frames, low intensity images, and ambiguous or blended expressions; 256 frames met criteria and were rechecked by two expert judges. Images were retained if they depicted all the prototypical features of the designated expression. A final selection was conducted to assure an image set that covered all age ranges, both sexes and an even number of images by expression, resulting in 42 frames (21 male, six of each emotion). Expert judges, independent adults, independent teenagers, and a software validation were used to assure database validity. Agreement across raters was high, and no differences were observed for posed and spontaneous images. The data set developed in this study can be a valid tool in studies of facial expressions, in particular, with adolescents’ samples.

Dimensions of youth psychopathy differentially predict concurrent pro- and antisocial behavior

Objective: To investigate the unique contribution of narcissism and impulsivity, in addition to callous-unemotional (CU) traits, in explaining concurrent prosocial and antisocial behavior. Method: Two hundred and forty-nine schoolchildren (53% female; age 9-12 years) completed the self-report Strengths and Difficulties Questionnaire (SDQ) and the Antisocial Process Screening Device (APSD). Two statistical models were tested, predicting conduct problems (CP) and prosocial behavior (PB). In the first one, CU traits and gender were entered into the equation. The second model added narcissism and impulsivity. Results: Gender, narcissism and impulsivity, but not CU, were statistically significant predictors of CP in the second model (F3,226 = 45.07, p < 0.001, R2 = 43.7%; betas: gender = -0.20, narcissism = 0.29, impulsivity = 0.36, CU = 0.06). PB was significantly predicted by all domains except gender (F3,226 = 42.57, p < 0.001, R2 = 42.4%; betas: gender = 0.08, narcissism = -0.16, impulsivity = -0.23, CU = -0.41). Conclusion: Our results confirmed that CU traits refer to a distinct manifestation of psychopathy in youth, but we also found that narcissism and impulsivity are equally important when predicting CP. Previous reports of sex differences on APSD and SDQ domains were also corroborated.
