Clinical validation of ratings on the six-item Positive and Negative Syndrome Scale obtained via the Simplified Negative and Positive Symptoms Interview.

Background: The six-item version of the Positive and Negative Syndrome Scale (PANSS-6) has shown promise as a brief measure of the severity of core symptoms of schizophrenia. However, since all prior analyses of the PANSS-6 were based on data extracted from studies using the full 30-item PANSS (PANSS-30), it remains unknown whether it is possible to obtain valid information for the PANSS-6 ratings via a brief interview, such as the Simplified Negative and Positive Symptoms Interview (SNAPSI).

Aims: We aimed to validate the PANSS-6 ratings obtained via the SNAPSI using the PANSS-6 scores extracted from the PANSS-30 ratings obtained via the comprehensive Structured Clinical Interview for PANSS (SCI-PANSS) as the gold-standard reference.

Inter-rater reliability of ratings on the six-item Positive and Negative Syndrome Scale (PANSS-6) obtained using the Simplified Negative and Positive Symptoms Interview (SNAPSI).

Purpose: The six-item version of the Positive And Negative Syndrome Scale (PANSS-6) is a brief rating scale focusing on core symptoms of schizophrenia. In order to facilitate rating of PANSS-6 and selected items from other common psychiatric rating scales, we recently developed the Simplified Negative and Positive Symptoms Interview (SNAPSI). The objective of the present study was to test the inter-rater reliability of PANSS-6 ratings obtained using the SNAPSI.

Reliability and validity of the German version of the Maternal-Fetal Attachment Scale.

Objectives: In understanding early disturbances in the mother-child relationship, maternal-fetal attachment has become an important concept. To date no study has investigated the reliability and validity of the German version of the Maternal Fetal Attachment Scale (MFAS). The present study aimed to close this gap.

Maternal self-confidence during the first four months postpartum and its association with anxiety and early infant regulatory problems.

Maternal self-confidence has become an essential concept in understanding early disturbances in the mother-child relationship. Recent research suggests that maternal self-confidence may be associated with maternal mental health and infant development. The current study investigated the dynamics of maternal self-confidence during the first four months postpartum and the predictive ability of maternal symptoms of depression, anxiety, and early regulatory problems in infants.

Sexual activity and sexual dysfunction of women in the perinatal period: a longitudinal study.

Purpose: Reduced sexual activity and dysfunctional problems are highly prevalent in the perinatal period, and there is a lack of data regarding the degree of normality during pregnancy. Several risk factors have been independently associated with a greater extent of Female Sexual Dysfunction (FSD). Therefore, this study aimed to assess the prevalence of sexual inactivity and sexual dysfunctions in German women during the perinatal period and the verification of potential risk factors.

Predictors of impaired breastfeeding initiation and maintenance in a diverse sample: what is important?

Purpose: This study aimed to investigate socio-demographic, medical and psychological factors that have an impact on breastfeeding.

Methods: Questionnaires were administered to 330 women prenatally (TI third trimester) and postpartum (TII 3-4 days, TIII 4 months). Medical data were collected from the hospital records.
