The Family Alliance Model: A Way to Study and Characterize Early Family Interactions.

The aim of this paper is to present the family alliance (FA) model, which is designed to conceptualize the relational dynamics in the early family. FA is defined as the coordination a family can reach when fulfilling a task, such as playing a game or having a meal. According to the model, being coordinated as a family depends on four interactive functions: participation (all members are included), organization (members assume differentiated roles), focalization (family shares a common theme of activity), affect sharing (there is empathy between members). The functions are operationalized through the spatiotemporal characteristics of non-verbal interactions: for example, distance between the partners, orientation of their bodies, congruence within body segments, signals of readiness to interact, joint attention, facial expressions. Several standardized observational situations have been designed to assess FA: The Lausanne Trilogue Play (with its different versions), in which mother, father, and baby interact in all possible configurations of a triad, and the PicNic Game for families with several children. Studies in samples of non-referred and referred families (for infant or parental psychopathology) have highlighted different types of FA: disorganized, conflicted, and cooperative. The type of FA in a given family is stable through the first years and is predictive of developmental outcomes in children, such as psychofunctional symptoms, understanding of complex emotions, and Theory of Mind development

SYSTEMS FOR LIGHT DIFFUSION THROUGH TRANSPARENT MATERIALS: PERFORMANCE INDEXES RELATED TO THE CONTAINMENT OF LUMINANCE AND TO THE REMOVAL OF THE UV COMPONENT

This article relates the results of some research, the first phase of which has been presented in a CIE Convention in 2002. The subject of the research is the study of the materials usually employed for light diffusion, in particular the commercial and exhibition applications. In both cases, the role these materials have in the removal of the most damaging component of light, that is the power issued in UV fields, is pivotal. Altogether, the research involved different types of glass, micro-drilled metal plates, plastic materials and film

How much do combined affective and cognitive impairments worsen rehabilitation outcomes after hip fracture ?

To investigate the association between isolated and combined affective and cognitive impairments with functional outcomes and discharge destination in older patients admitted to rehabilitation after a hip fracture. Prospective study in 612 community-dwelling patients aged 65 years and over, admitted to rehabilitation after surgery for hip fracture. Information on socio-demographics, medical, functional, affective, and cognitive status was systematically collected at admission. Functional status, length of stay and destination were assessed at discharge. Functional improvement was defined as any gain on the Barthel Index score between admission and discharge from rehabilitation. At admission, 8.2% of the patients had isolated affective impairment, 27.5% had cognitive impairment only, and 7.5% had combined impairments. Rate of functional improvement steadily decreased from 91.2% in patients with no cognitive nor affective impairment to 73.8% in those with combined impairments. Compared to patients without any impairment, those with combined impairments had lower odds of functional improvement, even after adjustment for age, gender, health and functional status at admission (adjOR: 0.40; 95%CI: 0.16-1.0; p = .049). The proportion of patients discharged back home gradually decreased from 82.8% among patients without any impairment to only 45.6% in patients with combined impairments. In multivariate analysis, the odds of returning home remained significantly reduced in these latter patients (adjOR: 0.31; 95%CI:0.15-0.66; p = .002). Affective and cognitive impairments had both independent, and synergistic negative association with functional outcome and discharge destination in patients admitted to rehabilitation after a hip fracture. Nevertheless, patients with combined affective and cognitive impairments still achieved significant functional improvement, even though its magnitude was reduced. Further studies should investigate whether these patients would benefit from better targeted, longer, or more intensive rehabilitation interventions to optimize their functional recovery

Coparenting Behaviors as Mediators between Postpartum Parental Depressive Symptoms and Toddler's Symptoms.

Postpartum parental depression, even of mild intensity and short duration, has negative consequences on child development, including increased externalizing and internalizing symptoms. Studies revealed that the links between parental depression and child development are mediated by parenting difficulties. On the other hand, the mediating role of problematic family-level relationships, such as low coparenting support and high conflict between the parents, has rarely been considered, although coparenting difficulties have been linked with both increased depressive symptoms in parents and increased symptoms in toddlers. In the present study, we proposed testing a comprehensive mediation model linking parental depression, coparenting, and child symptoms. At 3 months postpartum, a convenience sample of 69 parental couples completed the Edinburgh Postnatal Depression Scale. In addition, we assessed levels of coparenting support and conflict during a mother-father-infant play situation, the Lausanne Trilogue Play. At 18 months postpartum, both parents assessed child symptoms with the Symptom Checklist Questionnaire. The results showed that coparenting support mediated the links between parental depressive symptoms and child symptoms, but only for mothers: Maternal depressive symptoms were linked with lower coparenting support, which in turn predicted increased psychofunctional symptoms and behavior problems assessed by mothers. Although coparenting conflict behaviors were not predicted by parents' depressive symptoms, higher conflict was unexpectedly linked with fewer behavior problems assessed by both parents. The present study allowed us to unveil complex pathways between mild parental mood disturbances, family-level relationships, and child development in the first months of the child's life

Variations in fathers' discourse on fatherhood and in family alliances during infancy

The aim of this pilot study is to analyse the discourse of fathers of toddlers concerning fatherhood and the link between some particularities in the discourse and family alliance. The sample consists of 13 Swiss first time fathers (5 fathers of girls and 8 of boys). In order to evaluate the paternal discourse, the fathers were given a semistructured interview, which was later analysed using the research package Alceste. The family alliance, i.e., the degree of coordination among the partners when executing a task together, was assessed through the Lausanne Trilogue Play (Fivaz-Depeursinge & Corboz-Warnery, 1999). The main results indicated an interesting link between classes of paternal discourse grouped around the following themes "affective relationship”, "daily routine” and "educational goals”, and the family alliance (defined in two major categories; functional and problematic alliances). Finally, clinical perspectives on links between paternal representations and family functioning at an interactive level are discusse

The Family Alliance Assessment Scales: Steps Toward Validity and Reliability of an Observational Assessment Tool for Early Family Interactions

We present the first steps in the validation of an observational tool for father-mother-infant interactions: the FAAS (Family Alliance Assessment Scales). Family-level variables are acknowledged as unique contributors to the understanding of the socio-affective development of the child, yet producing reliable assessments of family-level interactions poses a methodological challenge. There is, therefore, a clear need for a validated and clinically relevant tool. This validation study has been carried out on three samples: one non-referred sample, of families taking part in a study on the transition to parenthood (normative sample; n=30), one referred for medically assisted procreation (infertility sample; n=30) and one referred for a psychiatric condition in one parent (clinical sample; n=15). Results show that the FAAS scales have (1) good inter-rater reliability and (2) good validity, as assessed through known-group validity by comparing the three samples and through concurrent validity by checking family interactions against parents' self-reported marital satisfactio

A Longitudinal Study of Parental Depressive Symptoms and Coparenting in the First 18 Months.

Although the negative impact of postpartum depression on parenting behaviors has been well established-albeit separately-for mothers and fathers, the respective and joint impact of both parents' mood on family-group interactive behaviors, such as coparenting support and conflict behaviors between the parents, have not yet been investigated. The aim of this study was to examine the association between parental depressive symptoms and coparenting behaviors in a low-risk sample of families with infants, exploring reciprocity between the variables, as well as gender differences between mothers and fathers regarding these links. At 3 (T1), 9 (T2), and 18 months postpartum (T3), we assessed both parents' depressive symptoms with a self-report questionnaire and observed coparenting support and conflict during triadic mother-father-child interactions. The results revealed that higher maternal depressive symptoms at T1 were associated with lower support at T1 and T2. Conflict at T3 was associated with higher maternal depressive symptoms at T3 and, more surprisingly, with less depressive symptoms in mothers at T2 and fathers at T3. Cross-lagged associations suggested that parental depressive symptoms were more likely to influence coparenting than the reverse. Moreover, maternal depressive symptoms were more likely to be linked to coparenting behaviors than were paternal depressive symptoms. These results confirm that parental-mostly maternal-depressive symptoms, even of mild intensity, may jeopardize the development of healthy family-level relations, which previous research has shown to be crucial for child development

Antagonism of neuromuscular blockade but not muscle relaxation affects depth of anaesthesia

Background. Conflicting effects of neuromuscular blocking drugs and anticholinesterases on depth of anaesthesia have been reported. Therefore we evaluated the effect of atracurium and neostigmine on bispectral index (BIS) and middle-latency auditory evoked potentials (AAI). Methods. We studied 40 patients (ASA I-II) aged 18-69 yr. General anaesthesia consisted of propofol and remifentanil by target-controlled infusion and neuromuscular function was monitored by electromyography. When BIS reached stable values, patients were randomly assigned to one of two groups. Group 1 received atracurium 0.4 mg kg−1 and, 5 min later, the same volume of NaCl 0.9%; group 2 received saline first and then atracurium. When the first twitch of a train of four reached 10% of control intensity, patients were again randomized: one group (N) received neostigmine 0.04 mg kg−1 and glycopyrrolate 0.01 mg kg−1, and the control group (G) received only glycopyrrolate. Results. Injection of atracurium or NaCl 0.9% had no effect on BIS or AAI. After neostigmine-glycopyrrolate, BIS and AAI increased significantly (mean maximal change of BIS 7.1 [sd 7.5], P<0.001; mean maximal change of AAI 9.7 [10.5], P<0.001). When glycopyrrolate was injected alone BIS and AAI also increased (mean maximal change of BIS 2.2 [3.4], P=0.008; mean maximal change of AAI 3.5 [5.7], P=0.012), but this increase was significantly less than in group N (P=0.012 for BIS; P=0.027 for AAI). Conclusion. These data suggest that neostigmine alters the state of propofol-remifentanil anaesthesia and may enhance recover

Prenatal coparenting alliance and marital satisfaction when pregnancy occurs after assisted reproductive technologies or spontaneously

Although the coparenting relationship has been described as key in family dynamics, very few studies have assessed its development during pregnancy after assisted reproductive technology (ART). In this study, the authors compared the prenatal coparenting relationship in 33 couples who conceived through ART with that of 49 couples who conceived spontaneously, and assessed the association between marital satisfaction and the prenatal coparenting alliance. The first-time parents were met during the second trimester of pregnancy. A validated observational task (the Prenatal Lausanne Trilogue Play) was used to assess their prenatal coparenting relationship, and the Dyadic Adjustment Scale was used to evaluate marital satisfaction. No differences were observed in the two groups\u2019 global prenatal coparenting scores, but the ART couples showed less coparental playfulness than those who conceived spontaneously. Marital satisfaction was higher in women who conceived through ART. These data suggest that infertility and its treatment affect the prenatal coparenting and marital relationships in different ways
