Sintomas depressivos e ansiosos em mães de recém-nascidos com e sem malformações

OBJETIVO: comparar as condições emocionais de mães cujos filhos nascem com malformações visíveis (Grupo M) com as das mães de crianças eutróficas (Grupo E) logo após o nascimento. MÉTODO: foram avaliados os sintomas de ansiedade e depressão de 22 mães de cada grupo por meio do Inventário de Depressão de Beck (BDI) e do Inventário de Ansiedade Traço-Estado (IDATE). Foram excluídas as mães portadoras de deficiência sensorial incapacitante, HIV, distúrbios psiquiátricos e síndromes genéticas. Os dados foram complementados com consultas a prontuários médicos da criança e da mãe. Para análise comparativa entre as medianas dos grupos foi utilizado o teste não-paramétrico U de Mann-Whitney; para amostras independentes e para os escores indicativos de sintomas clínicos, o teste exato de Fisher e o teste do χ2. RESULTADOS: houve diferenças significativas nas medianas dos escores das três subescalas (ansiedade-traço, ansiedade-estado e disforia/depressão) entre os dois grupos de mães. Houve uma porcentagem significativamente maior de mães do Grupo M com escores indicativos de sinais clínicos para depressão ou ansiedade no pós-parto imediato e, para ambos os quadros, quando comparadas com mães do Grupo E. Os resultados podem ser decorrentes de traços de personalidade materna, visto que os índices de ansiedade-traço eram significativamente maiores nas mães de crianças malformadas, mas especialmente pelo estado da criança, seu encaminhamento para a UTI e sua condição de vida futura. CONCLUSÕES: a porcentagem de mães de recém-nascidos com malformações visíveis que apresentou escores indicativos de sinais clínicos para ansiedade, depressão e ambos sugerem a necessidade de suporte, individual ou em grupo.

Assessment of Quality of Life and Psychologic Aspects in Patients with Gestational Trophoblastic Disease

OBJECTIVE: To assess quality of life (QoL) and psychological aspects in patients with gestational trophoblastic disease (GTD).METHODS: This cross-sectional self-report study was conducted among 54 women. Validated questionnaires assessed QoL (WHO-QOL-bref), symptoms of depression (Beck Depression Inventory [BDI]) and anxiety (State-Trait Anxiety Inventory [STAI]).RESULTS: Most patients rated overall QoL as good (44.44%) anti were satisfied with their health status (42.59%). Mean QoL domain score was lowest for psychologic health (53.86 +/- 21.46) and highest for social relationships (65.74 +/- 22.41). BDI mean was 15.81 +/- 11.15, indicating dysphoria. STAI means were 46 +/- 6.46 for trait-anxiety and 43.72 +/- 4.23 for state-anxiety, both evidencing medium-high anxiety. Among employed patients, environment domain mean was the highest (p = 0.024). Presence of children resulted in lowest means for physical health (p = 0.041) and environment (p = 0.045). Patients desiring children showed significantly higher means for physical health (p = 0.004), psychological health (p = 0.021) and environment (p = 0.003). Chemotherapy had no significant influence on QoL (p > 0.05).CONCLUSION: This study evidenced psychological impact on GTD patients, suggesting specialized care centers should provide psychological interventions during treatment and follow-up of GTD patients, highlighting the importance of a multidisciplinary approach.

Relationship between psychological factors and symptoms of TMD in university undergraduate students.

Temporomandibular disorders is a collective term used to describe a number of related disorders involving the temporomandibular joints, masticatory muscles and occlusion with common symptoms such as pain, restricted movement, muscle tenderness and intermittent joint sounds. The multifactorial TMD etiology is related to emotional tension, occlusal interferences, tooth loss, postural deviation, masticatory muscular dysfunction, internal and external changes in TMJ structure and the various associations of these factors. The aim of this study was to evaluate the prevalence of the relationship between signs of psychological distress and temporomandibular disorder in university students. A total 150 volunteers participated in this study. They attended different courses in the field of human science at one public university and four private universities. TMD was assessed by the Research Diagnostic Criteria (RDC) questionnaire. Anxiety was measured by means of a self-evaluative questionnaire, Spielberger's Trait-State anxiety inventory, to evaluate students'state and trait anxiety. The results of the two questionnaires were compared to determine the relationship between anxiety levels and severity degrees of chronic TMD pain by means of the chi-square test. The significance level was set at 5%. The statistical analysis showed that the TMD degree has a positive association with state-anxiety (p = 0.008; p < 0.05) and negative with trait-anxiety (p = 0.619; p < 0.05). Moreover a high TMD rate was observed among the students (40%). This study concluded that there is a positive association between TMD and anxiety.

Ethnic/racial diversity, maternal stress, lactation and very low birthweight infants.

OBJECTIVE: (1) To compare maternal characteristics and psychological stress profile among African-American, Caucasian and Hispanic mothers who delivered very low birthweight infants. (2) To investigate associations between psychosocial factors, frequency of milk expression, skin-to-skin holding (STS), and lactation performance, defined as maternal drive to express milk and milk volume. STUDY DESIGN: Self-reported psychological questionnaires were given every 2 weeks after delivery over 10 weeks. Milk expression frequency, STS, and socioeconomic variables were collected. RESULT: Infant birthweight, education, and milk expression frequency differed between groups. Trait anxiety, depression and parental stress in a neonatal intensive care unit (PSS:NICU) were similar. African-American and Caucasian mothers reported the lowest scores in state anxiety and social desirability, respectively. Maternal drive to express milk, measured by maintenance of milk expression, correlated negatively with parental role alteration (subset of PSS:NICU) and positively with infant birthweight and STS. Milk volume correlated negatively with depression and positively with milk expression frequency and STS. CONCLUSION: Differences between groups were observed for certain psychosocial factors. The response bias to self-reported questionnaires between groups may not provide an accurate profile of maternal psychosocial profile. With different factors correlating with maintenance of milk expression and milk volume, lactation performance can be best enhanced with a multi-faceted intervention program, incorporating parental involvement in infant care, close awareness and management of maternal mental health, and encouragement for frequent milk expression and STS.

Glucocorticoids enhance in vivo exposure-based therapy outcome in spider phobia

BACKGROUND: Preclinical and clinical studies indicate that the administration of glucocorticoids may promote fear extinction processes. In particular, it has been shown that glucocorticoids enhance virtual reality based exposure therapy of fear of heights. Here, we investigate whether glucocorticoids enhance the outcome of in vivo exposure-based group therapy of spider phobia. METHODS: In a double blind, block-randomized, placebo-controlled, between-subject study design, 22 patients with specific phobia of spiders were treated with two sessions of in vivo exposure-based group therapy. Cortisol (20 mg) or placebo was orally administered 1 hr before each therapy session. Patients returned for a follow-up assessment one month after therapy. RESULTS: Exposure-based group therapy led to a significant decrease in phobic symptoms as assessed with the Fear of Spiders Questionnaire (FSQ) from pretreatment to immediate posttreatment and to follow-up. The administration of cortisol to exposure therapy resulted in increased salivary cortisol concentrations and a significantly greater reduction in fear of spiders (FSQ) as compared to placebo at follow-up, but not immediately posttreatment. Furthermore, cortisol-treated patients reported significantly less anxiety during standardized exposure to living spiders at follow-up than placebo-treated subjects. Notably, groups did not differ in phobia-unrelated state-anxiety before and after the exposure sessions and at follow-up. CONCLUSIONS: These findings indicate that adding cortisol to in vivo exposure-based group therapy of spider phobia enhances treatment outcome.

Effects of physical and psychological stressors on adolescents’ cortisol levels and self-perceived stress in school

Both, psychosocial stress and exercise in the past have been used as stressors to elevate saliva cortisol and change state anxiety levels. In the present study, high-school students at the age of 14 were randomly assigned to three experimental groups: (1) an exercise group (n = 18), that was running 15 minutes at a medium intensity level of 65-75% HRmax, (2) a psychosocial stress group (n = 19), and (3) a control group (n = 18). The psychosocial stress was induced to the students by completing a standardized intelligence test under the assumption that their IQ scores would be made public in class. Results display that only psychosocial stress but not exercise was able to significantly increase cortisol levels but decreased cognitive state anxiety in adolescents. The psychosocial stress protocol applied here is proposed for use in future stress studies with children or adolescents in group settings, e.g., in school.

Entwicklung der Fünf-Item-Kurzskala STAI-SKD zur Messung von Zustandsangst

Das State-Trait-Angstinventar (STAI) ist eines der am häufigsten eingesetzten Erhebungsinstrumente im Bereich der Angstdiagnostik. Die STAI-Skala zur Erfassung von Zustandsangst umfasst 20 Items. Unter bestimmten Erhebungsbedingungen erweist es sich als relativ schwierig, eine große Menge an Items zu bearbeiten oder aber es steht nicht ausreichend Testzeit zur Verfügung. Daher war es das Ziel der vorliegenden Studie, eine Kurzform der State-Version des STAI zu entwickeln. An einer Stichprobe von N = 65 Studierenden wurde aufgrund inhaltlicher und statistischer Kriterien eine Kurzform der State-Version des STAI, das STAI-SKD, mit fünf Items generiert. Eine konfirmatorische Faktorenanalyse an einer zweiten Stichprobe von N = 191 Studierenden zeigte, dass das STAI-SKD die Angstkomponenten Emotionality und Worry abbildet. Die Beziehungen des STAI-SKD zu positivem und negativem Affekt sowie dessen Veränderungssensitivität fielen in einer dritten Stichprobe (N = 80 Studierende) erwartungsgemäß aus. Die neue Kurzform der State-Version des STAI erlaubt eine ökonomische Erfassung der Zustandsangst.

Ego depletion and attention regulation under pressure: Is a temporary loss of self-control strength indeed related to impaired attention regulation?

In the current study we investigated whether ego depletion negatively affects attention regulation under pressure in sports by assessing participants' dart throwing performance and accompanying gaze behavior. According to the strength model of self-control, the most important aspect of self-control is attention regulation. Because higher levels of state anxiety are associated with impaired attention regulation, we chose a mixed design with ego depletion (yes vs. no) as between-subjects and anxiety level (high vs. low) as within-subjects factor. Participants performed a perceptual-motor task requiring selective attention, namely, dart throwing. In line with our expectations, depleted participants in the high-anxiety condition performed worse and displayed a shorter final fixation on bull's eye, demonstrating that when one's self-control strength is depleted, attention regulation under pressure cannot be maintained. This is the first study that directly supports the general assumption that ego depletion is a major factor in influencing attention regulation under pressure.

Ego depletion and attention regulation under pressure: Is a temporary loss of self-control strength indeed related to impaired attention regulation?

In the present study we investigated whether ego depletion negatively affects attention regulation under pressure in sports by assessing participants’ dart throwing performance and accompanying gaze behavior. According to the strength model of self-control the most important aspect of self-control is attention regulation (Schmeichel & Baumeister, 2010). As higher levels of state anxiety are associated with impaired attention regulation (Nieuwenhuys & Oudejans, 2012) we chose a mixed design with ego depletion (yes vs. no) as between-subjects and anxiety level (high vs. low) as within-subjects factor. A total of 28 right-handed students participated in our study (Mage = 23.4, SDage = 2.5; 10 female; no professional dart experience). Participants performed a perceptual-motor task requiring selective attention, namely, dart throwing. The task was performed while participants were positioned high and low on a climbing wall (i.e., with high and low levels of anxiety). In line with our expectations, a mixed-design ANOVA revealed that depleted participants in the high anxiety condition performed worse (p < .001) and displayed a shorter final fixation on bull’s eye (p < .01) than in the low anxiety condition, demonstrating that when one is depleted attention regulation under pressure cannot be maintained. This is the first study that directly supports the general assumption that ego depletion is a major factor in influencing attention regulation under pressure.

A methodologic study of pain assessment in Anglo and Hispanic children with cancer

There is growing clinical evidence that even young children experience pain and accompanying anxiety. Few instruments have been validated to assess pain characteristics in children. The study of related demographic, illness, psychologic and parental factors in children has also been limited. This study examines the reliability and validity of pain assessment tools in an outpatient pediatric cancer population. A total of 78 children from three to fifteen years of age were observed and interviewed about the pain of invasive procedures. The effect of cultural factors and the stress of acculturation were examined by comparing data from two cultural groups, Anglo and Hispanic.^ Spielberger State-Trait Anxiety Scales were administered to children and parents prior to an invasive procedure. The Procedure Behavioral Checklist (PBCL) was used for observation of the child's response during the procedure. The Children's Procedural Interview (CPI) which contains items on the PBCL and visual analogues (scales of faces indicating varying degrees of pain and anxiety) was administered following the procedure.^ Reliability coefficients for Anglos were.78 on the PBCL,.79 on the CPI and.85 on the visual analogue scales. For Hispanics, the reliability for the PBCL was.54, while the CPI had a reliability of.72 and the visual analogue scales,.87. Construct validity was demonstrated by high correlations between the PBCL and CPI scores for both ethnic groups (.66 for Anglos and.64 for Hispanics) and by the significant correlation of State anxiety scores with both PBCL and CPI scores. Age was inversely correlated with PBCL and CPI scores for both ethnic groups. Hispanic parents' anxiety scores were higher than Anglo parents, but were not highly correlated with their child's PBCL, CPI or State-Trait anxiety scores. Caregivers' ratings were correlated with the PBCL scores for Anglos but not for Hispanics.^ The findings of this study indicate that pain responses may be reliably assessed using both observational and self-report methods in children, though differences in Anglo and Hispanic cultures exist. Differences in pain symptomatology and assessment in the two cultural groups warrant further study. ^

Relaciones entre ansiedad escolar, ansiedad rasgo, ansiedad estado y depresión en una muestra de adolescentes españoles

Diferentes estudios han analizado la ansiedad escolar como un constructo unitario sin atender a las diferentes situaciones y sistemas de respuesta que conforman este constructo. El presente estudio considera la ansiedad escolar como un constructo multidimensional y su objetivo fue analizar las relaciones y capacidad predictiva de las situaciones y sistemas de respuesta de la ansiedad escolar sobre la ansiedad rasgo, la ansiedad estado y la depresión. El Inventario de Ansiedad Escolar (IAES), el Inventario de Ansiedad Estado-Rasgo (STAI y STAIC) y el Inventario de Depresión Infantil (CDI) fueron administrados a una muestra de 1409 estudiantes españoles de 12 a 18 años de edad. Los resultados muestran correlaciones positivas y significativas entre las situaciones y respuestas de ansiedad escolar con ansiedad rasgo, ansiedad estado y depresión. Además, la mayoría de factores situacionales y sistemas de respuesta de la ansiedad escolar son predictores significativos y positivos de la ansiedad rasgo, la ansiedad estado y la depresión. Las implicaciones prácticas de estos resultados son discutidas.

Selective attention for threatening information in anxious mood states

Attention for threatening information was investigated using a computerised version of the emotional Stroop. The study examined the influence of state and trait anxiety in an unselected student sample assigned to high trait anxious (HTA) or low trait anxious (LTA) groups on the basis questionnaire scores. State anxiety was manipulated within participants through the threat of electric shock. Threatening words that were either unrelated (e.g., cancer, danger) or related to the source of the threat (e.g., electrocute, shock) were presented to participants both within and outside of awareness. In the latter condition, a backward masking procedure was used to prevent awareness of the stimulus material. In the masked condition, despite chance performance in identification of the lexical status of stimulus items, HTA participants showed facilitated colour naming for all threat words relative to control items under threat of shock, but this effect was not evident in the shock safe condition. For unmasked trials the HTA group showed significant interference in colour naming for all threat words relative to controls under the threat of shock, but not in the shock safe condition. Neither valence of the items nor the threat of shock influenced colour naming latencies for the LTA group. [ABSTRACT FROM AUTHOR]

Widespread sensory hypersensitivity is a feature of chronic whiplash-associated disorder but not chronic idiopathic neck pain

Objectives: To investigate sensory changes present in patients with chronic whiplash-associated disorders and chronic idiopathic neck pain using a variety of quantitative sensory tests to better understand the pain processing mechanisms underlying persistent symptoms. Methods: A case control study was used with 29 subjects with chronic whiplash-associated disorders, 20 subjects with chronic idiopathic neck pain, and 20 pain-free volunteers. Pressure pain thresholds were measured over the articular pillars of C2-C3, C5-C6, the median, radial, and ulnar nerve trunks in the arm and over a remote site, the muscle belly of tibialis anterior. Heat pain thresholds, cold pain thresholds, and von Frey hair sensibility were measured over the cervical spine, tibialis anterior, and deltoid insertion. Anxiety was measured with the Short-Form of the Spielberger State Anxiety Inventory. Results: Pressure pain thresholds were decreased over cervical spine sites in both subject groups when compared with controls (P < 0.05). In the chronic whiplash-associated disorders group, pressure pain thresholds were also decreased over the tibialis anterior, median, and radial nerve trunks (P < 0.001). Heat pain thresholds were decreased and cold pain thresholds increased at all sites (P < 0.03). No differences in heat pain thresholds or cold pain thresholds were evident in the idiopathic neck pain group at any site compared with the control group (P > 0.27). No abnormalities in von Frey hair sensibility were evident in either neck pain group (P > 0.28). Discussion: Both chronic whiplash-associated disorders and idiopathic neck pain groups were characterized by mechanical hyperalgesia over the cervical spine. Whiplash subjects showed additional widespread hypersensitivity to mechanical pressure and thermal stimuli, which was independent of state anxiety and may represent changes in central pain processing mechanisms. This may have implications for future treatment approaches.
