Short forms of the postpartum depression screening scale: as accurate as the original form.

The aims of the present study were to develop three shorter forms of the Portuguese version of the Postpartum Depression Screening Scale (PDSS) as adapted and translated in Portugal, to analyse their psychometrics and to determine their cut-off points and associated conditional probabilities to screen for perinatal depression according to DSM-IV and ICD-10 criteria. In this study, 441 women in the third trimester of pregnancy and 453 in the third month of postpartum were interviewed for diagnostic purposes according to the Portuguese versions of the Diagnostic Interview for Genetic Studies and the Operational Criteria Checklist for Psychotic Illness. DSM-IV and ICD-10 classifications of depression were our gold standards for caseness. Three different shorter forms of the original Portuguese version of the PDSS were developed on the basis of reliability and factorial analysis. PDSS short versions, composed of seven and 21 (postpartum)/24 (pregnancy) items, presented significant reliability and validity and showed satisfactory combinations of sensitivity and specificity (≅80 %). The short forms of the original Portuguese version of the PDSS are valid alternatives to the 35-item version, given their equally precise screening performances, more concise structures and ease of completion.

The role of perfectionism in postpartum depression and symptomatology.

The role of perfectionism as a correlate and as a predictor of perinatal depressive symptomatology and disorder was examined. Three-hundred and eighty-six pregnant women (mean age = 30.08 years; SD = 4.205; range = 19-44) completed the Portuguese versions of the Multidimensional Perfectionism Scale, Beck Depression Inventory-II/BDI-II and three questions evaluating anxiety trait, life stress and social support perception. Diagnoses of depression were obtained using the Portuguese version of the Diagnostic Interview for Genetic Studies/OPCRIT system. Women who were depressed in pregnancy (ICD-10/DSM-IV) were excluded from the analyses. Self-Oriented Perfectionism and Socially Prescribed Perfectionism subcomponents (Conditional Acceptance and Others' High Standards) were significant correlates of depressive symptomatology/BDI-II in pregnancy. Others' High Standards was a significant predictor of postpartum depressive symptomatology/BDI-II, after controlling the other independent variables (depressive symptomatology and trait anxiety in pregnancy, life stress and social support perception in postpartum). None of the perfectionism subscales predicted postpartum depressive disorder (ICD-10/DSM-IV). Self-Oriented Perfectionism was an important correlate of depressive symptomatology in pregnancy and Others' High Standards and Conditional Acceptance were significant correlates of perinatal depressive symptomatology. Others' High Standards accounted for 0.8 % of the depressive symptomatology variance in postpartum after controlling the effect for other depressive symptomatology correlates. Perfectionism was not a risk factor for postpartum depressive disorder. Our findings improve the knowledge regarding the risk factors implicated in the development of postpartum depressive symptomatology/disorder, which is of utmost importance to develop adequate prevention and intervention strategies.

Sleep disturbances, body mass index and eating behaviour in undergraduate students.

This study investigates the association between sleep disturbances, body mass index (BMI) and eating behaviour in a sample of undergraduate students. The sample comprises 870 medicine and dentistry students from Coimbra University (62.5% females), aged between 17 and 25 years. The Eating Attitudes Test-40 was used to measure eating behaviour, and two questions were applied addressing difficulties of initiating sleep (DIS) and difficulties of maintaining sleep (DMS). A sleep disturbance index (SDI) was calculated from the sum of DIS and DMS scores. Body mass index (BMI) was determined from self-reported weight and height. The correlation analyses generally indicated that global eating disturbance, bulimic behaviour dimension and social pressure to eat were associated particularly with sleep difficulties. An association between diet concerns and sleep difficulties was less consistent. Regression analyses showed that bulimic behaviour (BB) and social pressure to eat (SPE) dimensions were associated significantly with sleep difficulties (DIS, DMS, SDI) in the total sample (BB: from P<0.01 to P<0.001; SPE: P<0.05) and in males (BB: from P<0.05 to P<0.001; SPE: P<0.05) and with insomnia symptoms (P<0.01). In females, bulimic behaviour was the only factor associated significantly with sleep difficulties (SDI, DIS; P<0.01) and with insomnia symptoms (P<0.05). Although BMI was correlated negatively with sleep difficulties (P<0.05), regression analyses indicated that it was not associated significantly with them. Our findings support an association between eating behaviour and sleep disturbances in both genders, which may have treatment implications.

Is insomnia in late pregnancy a risk factor for postpartum depression/depressive symptomatology?

The aim of the present work was to investigate if insomnia in late pregnancy is a risk factor for postpartum depressive symptomatology/postpartum depression (PPD). 581 women in their last trimester of pregnancy answered questions/questionnaires about lifetime history of insomnia, current sleep perception, current mood and depressive symptomatology. They were interviewed with the Portuguese version of the Diagnostic Interview for Genetic Studies. After delivery 382 (65.7%) mothers participated again in the study. Insomnia in pregnancy was not a risk factor for PPD (DSM-IV or ICD-10) but was a significant predictor of postpartum depressive symptomatology. Negative Affect (NA) was a significant predictor of postpartum depressive symptomatology. Women with higher NA were 4.6 (CI95%=1.69-12.74) and 5.3 times (CI95%=2.26-12.58) more likely of experiencing PPD (DSM-IV/ICD-10, respectively) than women with lower NA. Lifetime Depression was a significant predictor of postpartum depressive symptomatology and ICD-10/PPD (OR=2.6; CI95%=1.16-4.38). Positive Affect (PA) showed to be a protective factor for postpartum depressive symptomatology and DSM-IV/PPD (OR=1.5; CI95%=1.20-2.33). Controlling NA, PA and Lifetime Depression, insomnia lost its predictive role, suggesting these variables might work as mediators. Associations between insomnia, NA, PA and Lifetime Depression should be assessed in pregnancy. This might help to preventively target NA, enhance PA and reduce the likelihood of experiencing postpartum depressive symptomatology.

The postpartum depression screening scale: is it valid to screen for antenatal depression?

The purpose of the study was to analyse for the first time the validity of a slightly modified version of the Portuguese Postpartum Depression Screening Scale (PDSS), to be used as a screening instrument for antenatal depression. Specifically, the aims were to analyse its psychometric properties, to determine PDSS cutoff points and associated conditional probabilities to screen for depression according to DSM-IV and ICD-10 criteria and to compare its screening performance with that of the Beck Depression Inventory-II (BDI-II). Five hundred and three pregnant women in the third trimester of pregnancy completed both questionnaires and were interviewed face-to-face with the Portuguese version of the Diagnostic Interview for Genetic Studies. The Portuguese version of the Operational Criteria Checklist for Psychotic Illness was used to obtain DSM-IV and ICD-10 diagnoses of depression, our gold standards for caseness. PDSS reliability and validity were very good and comparable to those obtained in the postpartum validation studies developed in Portugal and in other countries, showing satisfactory sensitivity and specificity combinations (≅80%). Compared with BDI-II, it has the advantage of being more specific for the motherhood context. Although developed for postpartum depression, PDSS is accurate to screen for antenatal depression, and it could be very useful for clinical and epidemiologic purposes.

Effectiveness of psychological interventions in the treatment of perinatal depression: A systematic review of systematic reviews and meta-analyses.

BACKGROUND: Perinatal depression is a high prevalent mental health problem with serious consequences. Evidence about effective psychological interventions in treating perinatal depression has been increasing, but it lacks a comprehensive synthesis of findings. METHODS: A systematic review of systematic reviews and meta-analyses concerning the effectiveness of psychological interventions in treating perinatal depression (depression during pregnancy and the first 12 months postpartum) in adult women was conducted. The electronic databases MEDLINE (PubMed), PsycINFO, The Cochrane Library, Web of Science and Prospero were searched, on May 2020, using a combination of keywords. Data were independently extracted by two authors and a synthesis of the results was presented. Methodological quality was independently assessed by two authors, using AMSTAR-2. RESULTS: Seven systematic reviews were included and reported, overall, the effectiveness of psychological interventions in decreasing depressive symptoms in women in the perinatal period, both short and long-term. CBT was found to be the most effective intervention, regardless of the treatment format. LIMITATIONS: Grey literature was not searched, and some studies may overlap among the included systematic reviews. These (the included reviews) were rated with low methodological quality, which weakens the evidence of the reported results. CONCLUSIONS: CBT is currently the most evidence-based psychological intervention, provided in different delivery formats (individual, group, face-to-face or Internet-based). Further studies, including systematic reviews, with other types of psychological interventions (e.g., third-wave CBT) and with higher quality are needed.

Perfectionism dimensions in pregnancy--a study in Portuguese women.

Pregnancy is essentially a physiological event, but neuroendocrinal and psychosocial changes are also important components of this experience. In this context, perceived stress may be enhanced by the activation of certain personality traits, like perfectionism, which in turn may be associated with more psychological distress (PD). The aim of this study was to investigate if perfectionism could be associated with more negative emotional outcomes (PD) in the transition to motherhood and to look at which of the perfectionism dimensions these consequences are specifically linked. The sample comprises 421 pregnant women (mean = 29.8, SD = 4.48 years) who completed measures of perfectionism and mood symptoms. A two-factor model with self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) dimensions and a three-factor model with SOP, SPP-others' high standards and SPP-conditional acceptance (CA) factors were explored. Correlations and linear regressions were calculated between perfectionism factors and mood variables. Results showed that higher levels of SPP factors were associated with increased anxiety, depression, anger, fatigue and confusion, with decreased vigour and with more severe depressive symptoms. Our results, in contrast with those from the study of Campbell and DiPaula (2002, In: Flett G, Hewitt P (eds) Perfectionism. Theory, research, and practice. American Psychological Association, Washington, pp 181-198), did not confirm a preferential association between SPP-CA and PD, revealing that both components of SPP were associated with PD.

The BDI-II factor structure in pregnancy and postpartum: Two or three factors?

The purpose of the present study was to investigate the factor structure of the Beck Depression Inventory-II (BDI-II) in pregnancy and postpartum. Women were asked to fill in the BDI-II in their last trimester of pregnancy and at 3 months after delivery. A total of 331 pregnant women, with a mean age of 29.7 years (SD=4.6), and 354 mothers, aged 30.6 years (SD=4.6 years), answered the BDI-II. The first group was mainly nulliparas (65.6%) and the second group was mostly primiparas (57.4%). Factor analyses with principal components solution and varimax rotation were performed. Based on the scree test of Cattell a 2-factor solution and a 3-factor solution were explored. The 2-factor solution was identical in pregnancy and postpartum. Items loading in the Cognitive-Affective factor and in the Somatic-Anxiety factor were almost the same, though the Cognitive-Affective factor explained more of the BDI-II total variance in pregnancy, whereas in postpartum both factors explained similar total variances. The 3-factor solution of the BDI-II in pregnancy and postpartum slightly diverged. Besides the Cognitive-Affective and the Somatic-Anxiety factors, a third factor, Fatigue, was obtained in pregnancy while Guilt was the third factor identified in postpartum. This study reveals that the BDI-II 3-factor solution might be more appropriate to assess depressive symptoms in pregnancy and postpartum.

Perfectionism and eating attitudes in Portuguese students: a longitudinal study.

AIM: To investigate the role of perfectionism in the development of disordered eating behaviours. METHOD: 382 female university students completed the Hewitt & Flett MPS and the EAT-40 at baseline, and 1 year after (T1) and 206 2 years later (T2). RESULTS: Perfectionism at baseline was significantly associated with long-term abnormal eating attitudes/behaviours. Self-Oriented Perfectionism (SOP) and Socially Prescribed Perfectionism (SPP) were significant predictors of disordered eating behaviours. Regression analysis revealed that SOP at baseline was predictive of Diet Concerns and overall eating disturbance (EAT total score), at T1 and T2. SPP was a significant predictor of Social Pressure to Eat at T1 and T2 and of Bulimic Behaviours only at T1. CONCLUSION: Our findings contribute to a more clear understanding of the association between perfectionism and eating disorders. SOP and SPP were prospectively associated with abnormal eating attitudes/behaviours and SOP was found to be predictive of diet concerns and overall eating disturbance.

The Portuguese short form of the Eating Attitudes Test-40.

To develop a Portuguese short form, the Eating Attitudes Test-40 (EAT-40) was administered to a community sample of 922 female students and to a clinical sample of 63 females suffering from an eating disorder. With the EAT responses of the community sample a factor analysis was performed and items with factor loadings > or = 0.30 were selected. Internal consistency was computed for both the instrument and the factors. To study the discriminant capacity the proportion of symptomatic answers and the mean scores were compared between the clinical (N = 63) and control (N = 63) samples. Three factors were extracted: Drive for Thinness (14 items, alpha = .839), Bulimic Behaviours (8 items, alpha = .670), Social Pressure to Eat (3 items, alpha = .758). The short form is composed of 25 items and shows good internal consistency = 0.839. Symptomatic answers for all items (except one) and total mean scores were significantly higher (p < .001) in the clinical sample than in community sample.

Factor structure of the Rutter Teacher Questionnaire in Portuguese children.

OBJECTIVE: To examine the factor structure of the Rutter Teacher Questionnaire in Portuguese primary school children. METHOD: The Rutter Teacher Questionnaire, a 26-item scale covering a variety of behavioral problems, was completed by teachers of 877 children, aged 6 to 11 years. Data were subjected to factor analysis using the principal components solution with varimax rotation. RESULTS: The factorial analysis in total sample revealed three factors explaining 38.88% of the total variance. The factors contained items representing hyperactivity/conduct (Factor 1), anxious/depressive (Factor 2) and truancy/stealing (Factor 3). The highest correlations between factors scores were for Factor 1 and Factor 3. These Factors scores were higher in boys than girls and correlated with lower social class. All three Factors scores correlated with school performance. The comparison between separate factorial structures for the samples of boys and girls revealed a considerable overlap. CONCLUSIONS: The pattern of the items contained on Factor 1 appears to be related with the category of hyperkinetic conduct disorder used by the International Classification of Diseases-10. Results suggest that the Portuguese language version of the Rutter Teacher Questionnaire possesses good psychometric properties and may be considered a useful instrument for measuring children's behavior problems.

Perfectionism and eating attitudes in Portuguese university students.

OBJECTIVES: The main objective was to explore which are the dimensions of perfectionism that are linked to disordered eating behaviour (EB) in a large non-clinical sample of both genders. METHOD: One thousand one hundred and sixty-three undergraduate students of the University of Coimbra completed the Portuguese versions of the multidimensional perfectionism scale (MPS) and the eating attitudes test (EAT-40). RESULTS: In both genders, the MPS total score was associated with the EAT total score and all EAT dimensions (except for socially prescribed perfectionism in females). Self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) were associated with EAT total score, diet concerns (DC) and bulimic behaviour (BB) in females while in males the social prescribed perfectionism (SPP) was the useful predictor of EAT total score, BB and social pressure to eat (SPE). CONCLUSION: These results confirm that in general high levels of perfectionism are associated with abnormal EB. This was the case for both genders for SPP but for SOP for females only. The association for other oriented perfectionism (OOP) was greater for males than for females.

Ansiedade, depressão e estresse em estudantes universitários: o impacto da COVID-19 / Anxiety, depression and stress in university students: the impact of COVID-19

A pandemia e a inerente alteração de comportamentos, a par da parca previsibilidade, geraram maior ansiedade na população. Nesse sentido, este trabalho teve como objetivo analisar se os níveis de depressão, ansiedade e estresse em estudantes universitários se alteraram no período pandêmico (2020) comparativamente a períodos anteriores/normais. O estudo foi constituído por dois grupos, sendo a amostra 1 constituída por 460 sujeitos com idade média de 20,14 anos, e a amostra 2 por 159 sujeitos com idade média de 20,40 anos. Todos preencheram um questionário sociodemográfico e as escalas de ansiedade, depressão e estresse. Os estudantes que integraram o estudo no período pandêmico apresentaram níveis significativamente mais elevados de depressão, ansiedade e estresse comparativamente aos que integraram o estudo no período normal. Os resultados sugerem um impacto psicológico negativo da pandemia nos estudantes. Importa continuar a explorar as implicações da pandemia na saúde mental dos estudantes, para que se possam prevenir e minorar os seus efeitos.

The pandemic and the attendant change in behavior, together with the general unpredictability, has generated great anxiety in the population. In this context, the aim of this study was to analyze whether the levels of depression, anxiety and stress in university students have changed during the period of the pandemic (2020) compared with the previous normality. This study comprised two groups, in which sample-1 is composed of 460 subjects with a mean age of 20.14 and sample-2, 159 subjects with a mean age of 20.40. All the participants completed a sociodemographic questionnaire and were assessed by way of the Anxiety, Depression and Stress Scales. The students evaluated during the period of the pandemic presented significantly higher levels of anxiety, depression and stress, compared with students in erstwhile, normal times. Our results suggest that the pandemic has a negative psychological effect on students. It is important to continue exploring the implications of the pandemic on students' mental health, so that its effects can be prevented, or at least mitigated.

Adição à internet ou uso problemático da internet? Qual dos termos usar? / Dépendance à Internet ou utilisation problématique d'Internet? Quel terme utiliser? / Adición a Internet o uso problemático de Internet: ¿Qué término usar? / Internet addiction or problematic internet use? Which term should be used?

Resumo O uso da internet tem aumentado exponencialmente a nível mundial. Ainda que ele não seja por si só negativo, já que integra benefícios vários, alguns indivíduos parecem exibir problemas relacionados com o seu uso excessivo, descontrolado e disfuncional. Consequentemente, tem sido crescente, particularmente nas últimas duas décadas, o interesse dos investigadores em explorar este uso, quando excessivo e pouco saudável. Porém, e sendo um tema/constructo tratado por diferentes autores com quadros teóricos também diferentes, são vários os termos usados na literatura para descrever este fenómeno. Neste sentido, este artigo propõe-se a apresentar o trabalho uma revisão de literatura de dois dos conceitos mais usados e espartilhados na literatura científica, ou seja, adição à internet e uso problemático da internet.

Résumé L'utilisation d' Internet a augmenté de manière exponentielle dans le monde. Bien que l'utilisation d' Internet ne soit pas négative en soi, étant donné qu'elle intègre plusieurs avantages, certaines personnes semblent présenter des problèmes liés à son utilisation excessive, incontrôlée et dysfonctionnelle. En conséquence, l'intérêt des chercheurs pour exploiter cet usage, qu'il soit excessif ou malsain, a augmenté, particulièrement au cours des deux dernières décennies. Cependant, étant un thème/construit traité par différents auteurs avec différents cadres théoriques, plusieurs termes sont utilisés dans la littérature pour décrire ce phénomène. En ce sens, nous proposons de présenter dans cet ouvrage une analyse de deux des concepts les plus utilisés et les plus partagés dans la littérature scientifique, à savoir l'addition à internet et son utilisation problématique.

Resumen El uso de Internet ha aumentado exponencialmente a nivel mundial. Aunque esto no es por sí solo negativo ya que integra diversos beneficios, algunos individuos parecen presentar problemas relacionados con su uso excesivo, descontrolado y disfuncional. En consecuencia, en las últimas dos décadas ha aumentado cada vez más el interés de los investigadores en estudiar este uso, cuando es excesivo o poco saludable. Sin embargo, y siendo un tema/constructo tratado por diferentes autores con cuadros teóricos también diferentes, son varios los términos usados en la literatura para describir este fenómeno. En este sentido, nos proponemos presentar en este trabajo una revisión de dos de los conceptos más usados y más divididos en la literatura científica, es decir, adición a Internet y uso problemático de Internet.

Abstract Internet use has increased exponentially worldwide. Although the use itself is not negative, since it integrates several benefits, some individuals seem to show problems related to its excessive, uncontrolled, and dysfunctional use. Therefore, the interest of researchers in exploring this use, when it is excessive and unhealthy, has been growing, especially in the last two decades. However, being a subject/construct treated by different authors with different theoretical frameworks, several terms are used in the literature to describe this phenomenon. Regarding this, this article proposes to present a literature review of two of the most used and shared concepts in the scientific literature, that is, internet addiction and problematic internet use.

Sintomatologia depressiva no termo da gestação, em mulheres de baixo risco / Depressive symptomatology at full-term pregnancy in low risk women

RESUMO Objetivos Calcular a prevalência de sintomatologia depressiva pré-natal em grávidas de baixo risco, no termo da gestação, avaliar seus preditores e desfechos materno-fetais. Para tal, avaliar-se-á a aplicabilidade da Escala de Rastreio de Depressão Pós-Parto (PDSS 24) nessa fase da gravidez. Métodos A PDSS 24 e um questionário sociodemográfico, psicossocial e médico (antecedentes obstétricos e patológicos) foram autoaplicados a 403 grávidas (37-40 semanas de gestação), com idade média de 30,5 anos (DP = 4,67). Por meio do processo clínico, foram recolhidos dados de resultados materno-fetais. Resultados A PDSS 24 possui propriedades psicométricas adequadas para a deteção de sintomatologia depressiva pré-natal. A prevalência de sintomatologia depressiva pré-natal foi de 41,7%. Grávidas com níveis de escolaridade inferiores, não casadas, cuja gravidez não foi planejada e com antecedentes de acontecimentos de vida significativos apresentam risco duas vezes superior de sintomatologia depressiva no período pré-natal. Grávidas cujo apoio social percebido ao longo da gravidez não correspondeu ao desejado e com história prévia de depressão apresentam cerca de três vezes maior risco sintomatologia depressiva no período pré-natal. Para desfechos materno-fetais (pré-eclâmpsia, restrição de crescimento fetal, Apgar 1º/5º minuto, tipo de parto, percentil de peso, oligoâminos e necessidade de cuidados intensivos), as diferenças foram não significativas. Conclusão O rastreio da depressão pré-natal deve ser realizado na gravidez. Porém, no termo da gestação o uso da PDSS 24 como ferramenta de deteção de sintomatologia depressiva deve ser feito com cautela. A elevada prevalência de sintomas relacionados com o sono nessa fase da gestação pode conduzir ao sobre diagnóstico, usando a PDSS 24.

ABSTRACT Objectives The aims of the study were to estimate the prevalence of depressive symptomatology in full-term pregnancy (low risk), evaluate their predictors and maternal-fetal outcomes. To this end, the applicability of Postpartum Depression Screening Scale (PDSS 24) will be evaluated, at full-term pregnancy. Methods PDSS 24 and a sociodemographic, psychosocial, pathological and obstetrical background questionnaire were self-administered to 403 pregnant women (37-40 weeks gestation), with a mean age of 30.5 years (SD = 4.67). Data from maternal, fetal and neonatal outcomes were collected from the patient clinical process. Results PDSS 24 revealed adequate psychometric properties to screening depressive symptomatology in full-term pregnancy. The prevalence of depressive symptomatology was 41.7%. Pregnant women with lower study levels, who weren't married, whose pregnancy was unplanned and with a previous history of significant life events present twice the risk to present depressive symptomatology. Pregnant women who hadn't received the desired social support in pregnancy and with a history of depression present about a 3-fold increased risk to present depressive symptomatology. For maternal-fetal outcomes (pre-eclampsia, fetal growth restriction, Apgar score at 1st/5th minute, type of delivery, weight percentile, oligohydramnios and need for neonatal intensive care), the differences were not significant. Conclusion Screening for prenatal depression should be conducted during pregnancy. However, in full-term pregnancy women, the use of PDSS 24 as a screening tool for depressive symptomatology should be done with caution. The high prevalence of sleep-related symptoms, in full-term pregnancy, may lead to overdiagnosis, using PDSS 24.

Disordered eating behaviors and sleep disturbances.

The aim of the present study was to investigate if disordered eating behaviors predicted the development of sleep disturbances. A total of 870 students participated at baseline, 592 one year later (T1) and 305 two years later (T2). The Eating Attitudes Test-40 was used to assess global disordered eating behaviors, dietary concerns (DC), bulimic behaviors (BB) and social pressure to eat (SPE). Sleep disturbances were assessed by two items related to difficulties initiating sleep (DIS) and maintaining sleep (DMS). A sleep disturbance index (SDI) was calculated by summing DIS and DMS scores. Results revealed that global disordered eating behaviors at baseline predicted DIS, DMS and SDI at T1 and T2. Students with increased BB and SPE scores at baseline were more likely to experience sleep onset and sleep maintenance difficulties in the long term. These results suggest that assessment and correction of eating behaviors might prevent sleep disturbances.

Is positive affect in pregnancy protective of postpartum depression?

OBJECTIVE: To investigate the predictive/protective role of negative affect/positive affect in late pregnancy on the outcome of postpartum depression. METHODS: A total of 491 pregnant women participated in the study. The participants were asked to fill out a series of questionnaires, which included the Profile of Mood States, the Beck Depression Inventory-II, psychosocial variables and socio-demographic characteristics and were asked to participate in a psychiatric interview. After delivery, 272 mothers participated again in the study and filled out a similar series of questionnaires. RESULTS: Negative affect was associated with more intense depressive symptomatology, more self-perceived stress, lower self-reported social support, lower quality of life and perception of having a more difficult infant. By contrast, positive affect was negatively associated with these variables. Negative affect in late pregnancy increased the likelihood of experiencing postpartum depression (DSM-IV/OR = 2.1, 95%CI = 1.3-3.4, p = .003; ICD-10/OR = 2.1, 95%CI = 1.5-3.0, p < .001), while positive affect increased the odds of not having this condition (DSM-IV/OR = 2.0, 95%CI = 1.5-2.7, p = .042). CONCLUSION: In pregnancy, negative affect was a predictor of postpartum depression, whereas positive affect showed a protective role. Future studies are required to explore whether psychotherapeutic strategies focusing on decreasing negative affect and enhancing positive affect in the last trimester of pregnancy can reduce the risk of postpartum depression.

Epidemiology of perinatal depression in Portugal: categorical and dimensional approach.

The aim of the present study was to estimate depressive disorder and symptomatology prevalence and incidence in perinatal period in a population-based sample. Three-hundred and eighty six Portuguese women (mean age=30.08 years, SD=4.21) were interviewed with the Diagnostic Interview for Genetic Studies and completed Beck Depression Inventory-II/BDI-II and Postpartum Depression Screening Scale/PDSS, in pregnancy and postpartum. OPCRIT polydiagnostic system generated ICD-10 and DSM-IV diagnoses. One-month prevalence in pregnancy was of 2.3%/ICD-10 and 1.3%/DSM-IV; in postpartum it was of 16.6% and 11.7%. Pregnancy incidence was of 0%/ICD-10 and .3%/DSM-IV and in postpartum of 7.5%/ ICD-10 and 4.9%/DSM-IV. Depression pregnancy point-prevalence found with BDI-II cutoffs ranged from 13.7% to 19.4% in pregnancy and from .8% to 13.0% in postpartum and with PDSS from 14.2% to 17.9% in pregnancy and from 3.9% to 12.7% in postpartum. In the same sample, different diagnostic systems generated different prevalence and incidence rates. Higher prevalence rates were found using self-reported questionnaires. ICD-10 generated higher prevalence and incidence rates than DSM-IV.

Affective state dependence and relative trait stability of perfectionism in sleep disturbances.

OBJECTIVE: To evaluate the degree of absolute change, relative stability and state dependence of trait perfectionism in sleep disturbances in a sample of university students. METHOD: Participants completed the Multidimensional Perfectionism Scale and two items concerning sleep difficulties. The mean age at T0 (baseline) was 19.59 years (SD = 1.61, range = 17-25) and 62.5% of the sample were female. RESULTS: Absolute changes in self-oriented and socially-prescribed perfectionism were found. Relative stability was found for all perfectionism dimensions. Prior and concurrent sleep disturbances explained a significant amount of variance in perfectionism. Controlling for the effects of sleep measures, prior self-oriented perfectionism and other-oriented perfectionism were the only significant predictors of subsequent self-oriented perfectionism and other-oriented perfectionism, at T1 and T2. Difficulties falling asleep at T1 and socially-prescribed perfectionism at T0 were significant predictors of socially-prescribed perfectionism at T1. CONCLUSION: Despite significant changes in perfectionism mean scores over the follow-up, the correlation analyses demonstrated that participants remained quite stable in regard to their relative levels of perfectionism. As concurrent difficulties initiating sleep also predicted concurrent socially-prescribed perfectionism, this seems to be one dimension of perfectionism with trait-state characteristics.

Longitudinal study on perfectionism and sleep disturbance.

AIM: To examine if perfectionism predicts self-reported sleep disturbances over time. METHODS: The Hewitt-Flett Perfectionism Scale was used to assess self-oriented, socially-prescribed (SPP) and other-oriented perfectionism. Sleep disturbance was evaluated with two items: difficulty in falling asleep and waking up many times during the night. Out of 870 students who participated at baseline, 592 and 305 completed the same measures 1 year (T1) and 2 years later (T2), respectively. RESULTS: Subjects who reported insomnia at baseline, T1 and T2 (persistent insomnia) had significantly higher scores of baseline SPP (T1 M = 51.5, SD = 15.8; T2 M = 55.0, SD = 19.0) than subjects reporting, in all stages of the study, never/rarely having had sleep problems (T1 M = 41.9, SD = 11.4; T2 M = 42.2, SD = 12.3, P<0.001 in both cases). Regression analyses showed that baseline SPP was the only significant positive predictor of difficulties in falling asleep at T1 and T2 (T1 partial R=0.187; T2 partial R=0.196, P<0.001) and of difficulties maintaining sleep (T1 partial R=0.116; T2 partial R=0.244, P<0.001). CONCLUSION: SPP was found to be the most reliable predictor of sleep disturbances over time, which constitutes a new important finding.
