Protocol for the psychotherapeutic group intervention for facilitating posttraumatic growth in nonmetastatic breast cancer patients

Breast cancer can be perceived as a traumatic event with disturbing effects on psychological domains such as depression, anxiety, and Posttraumatic Stress Disorder. In contrast, growing evidence has shown that posttraumatic growth can occur as a result of coping with breast cancer. Challenging the assumptive world, deliberate rumination, and emotional disclosure are recognized as strong predictors of posttraumatic growth. Group interventions may also increase social support, distress disclosure, and posttraumatic growth. The aim of this study is to evaluate how group-based interventions can facilitate posttraumatic growth and promote improved psychosocial adjustment to breast cancer. This article describes the study protocol and the applied research methods.

Impact of a Cleft Lip and/or Palate on Maternal Stress and Attachment Representations.

Objective : The announcement, prenatally or at birth, of a cleft lip and/or palate represents a challenge for the parents. The purpose of this study is to identify parental working internal models of the child (parental representations of the child and relationship in the context of attachment theory) and posttraumatic stress disorder symptoms in mothers of infants born with a cleft. Method : The study compares mothers with a child born with a cleft (n  =  22) and mothers with a healthy infant (n  =  36). Results : The study shows that mothers of infants with a cleft more often experience insecure parental working internal models of the child and more posttraumatic stress symptoms than mothers of the control group. It is interesting that the severity or complexity of the cleft is not related to parental representations and posttraumatic stress disorder symptoms. The maternal emotional involvement, as expressed in maternal attachment representations, is higher in mothers of children with a cleft who had especially high posttraumatic stress disorder symptoms, as compared with mothers of children with a cleft having fewer posttraumatic stress disorder symptoms. Discussion : Mothers of children with a cleft may benefit from supportive therapy regarding parent-child attachment, even when they express low posttraumatic stress disorder symptoms.

État de stress post-traumatique chez les mères et chez les pères d'enfants prématurés: similitudes et différences = Prematurity and parental post-traumatic stress disorder: similarities and differences

Objectifs Évaluer et comparer la présence de symptômes de stress post-traumatique, en fonction de la gravité de la prématurité, chez les mères et chez les pères de bébés nés prématurément. Méthode En fonction du score de risque périnatal (PERI) du bébé, les parents des prématurés (âge gestationnel moins de 34 semaines) ont été divisés en deux groupes : les parents de prématurés à faible risque (n = 16) et à haut risque (n = 26). Les symptômes d'intrusion et d'évitement, de l'état de stress post-traumatique, ont été évalués chez les parents à l'aide d'un questionnaire, l'Impact of Event Scale (IES). Leurs réponses ont été comparées à un groupe témoin de parents de nouveau-nés à terme (n = 24). Les différences entre les réponses des mères et des pères, ont été analysées. Résultats Les parents de bébés prématurés sont plus à risque que les parents de nouveau-nés à terme de présenter des symptômes de stress post-traumatique. Les mères en lien avec le fait même de la prématurité du bébé, les pères en lien avec la gravité de la prématurité. Les mères et les pères des prématurés des deux groupes (prématurés à faible risque, prématurés à haut risque) décrivent des symptômes d'intrusion, alors que les symptômes d'évitement sont décrits par toutes les mères, mais seulement par les pères de prématurés à haut risque périnatal. Conclusion La naissance prématurée est susceptible d'entraîner l'apparition de symptômes de stress post-traumatique chez les parents. Les mères et les pères réagissent différemment. Objectives Evaluation of the symptoms of parental post-traumatic stress disorder (PTSD), according to the severity of the prematurity, in mothers and fathers of premature babies. Materials and methods According to the Perinatal Risk Inventory (PERI), the parents of premature infants (gestational age less than 34 weeks) were divided into two groups, parents of a low-risk premature infants (n = 16) and of high-risk premature infants (n = 26). The symptoms of intrusion and avoidance, as a part of the post-traumatic stress disorder, were evaluated by an autoadministrated questionnaire, the Impact of Event Scale (IES). Their responses were compared with a control group of parents of full-term infants (n = 24). The differences in the answers of mothers and fathers were analysed. Results The occurrence of symptoms of post-traumatic stress disorder is increased in parents of preterm infants compared with the control group. Whereas mothers of premature infants are at risk of presenting symptoms of PTSD, linked to the prematurity, with fathers the infant perinatal risk factors play a greater role. The symptoms of intrusion are present in mothers and fathers of preterm infants of both groups. Mothers of both groups present avoidance symptoms, although only fathers of high-risk preterm infants present them. Conclusions Premature birth has an impact on both parents in terms of post-traumatic stress reactions. However, mothers and fathers react in different ways according to the severity of the prematurity.

Posttraumatic stress symptoms and cortisol regulation in mothers of very preterm infants.

Previous studies have found that mothers of very preterm infants often report symptoms of posttraumatic stress, which has been related to cortisol dysregulation. However, the exact nature of this association is not clear and can be different regarding the predominance of some specific symptoms of posttraumatic stress, as suggested by a recent model. The objective of the present study is to assess the association between diurnal salivary cortisol and posttraumatic stress symptoms in mothers of very preterm infants. Seventy-four mothers of very preterm infants were included in the study. Mothers' cortisol regulation and posttraumatic stress symptoms were evaluated 12 months after child theoretical term (40 weeks of gestation). Results showed an association between higher re-experiencing symptoms and flatter cortisol slopes. These results may help to understand differences found in studies assessing the relation between severity of posttraumatic stress and cortisol levels, by supporting the symptoms' theory.

Validation française d'un questionnaire de stress post-traumatique destiné aux parents d'enfants présentant un risque périnatal élevé = French validation of the "Perinatal PTSD Questionnaire" assessing parent's posttraumatic stress reactions following the birth of a high risk infant.

(from the journal abstract) Objectives: The birth of a high risk infant--such as a very or extremely premature infant--can represent an important traumatic experience for parents. R. DeMier, M. Hynan et al's "Perinatal PTSD Questionnaire" aims at exploring, retrospectively, parent's posttraumatic stress reactions following the birth of a high risk infant. This paper describes the French validation of this questionnaire. Methods: Fifty-two families with a very or extremely premature infant and 25 families with a full term infant responded to the "Perinatal PTSD Questionnaire" and the "Impact of Event Scale" when children were 18 months old. Results: Parents of high risk infants can present posttraumatic stress reactions such as intrusion, avoidance or arousal symptoms. The French version of the "Perinatal PTSD Questionnaire" has satisfactory psychometric properties. Conclusions: As posttraumatic reactions are not directly related to objective descriptions of the stressful event, it may be essential to the liaison child psychiatrist to consider individual posttraumatic reactions in order to optimise preventive intervention with the parents. A questionnaire should not replace a clinical interview, however it may represent a useful screening tool. Also, this questionnaire should be useful for research purposes.

Effects of perinatal stress and maternal traumatic stress on the cortisol regulation of preterm infants.

Preterm infants experience intense stress during the perinatal period because they endure painful and intense medical procedures. Repeated activation of the hypothalamic-pituitary-adrenal (HPA) axis during this period may have long-term effects on subsequent cortisol regulation. A premature delivery may also be intensely stressful for the parents, and they may develop symptoms of posttraumatic stress disorder (PTSD). Usable saliva samples were collected (4 times per day over 2 days, in the morning at awakening, at midday, in the afternoon, and in the evening before going to bed) to assess the diurnal cortisol regulation from 46 preterm infants when the infants were 12 months of corrected age (∼ 14 months after birth). Mothers reported their level of PTSD symptoms. The results showed an interaction between perinatal stress and maternal traumatic stress on the diurnal cortisol slope of preterm infants (R(2) = .32). This suggests that the HPA axis of preterm infants exposed to high perinatal stress may be more sensitive to subsequent environmental stress.

Screening for post-traumatic stress disorder (PTSD) in a psychiatric emergency setting

Background and Objectives: (i) to assess the prevalence of PTSD in a psychiatric emergency setting by means of a diagnostic instrument and to compare it with PTSD-prevalence of a clinically evaluated, historical sample; and (ii) to assess psychiatric residents' perception of the systematic use of this diagnostic instrument. Methods: A consecutive sample of patients (N = 403) evaluated for a psychiatric emergency was assessed with the module J (PTSD) of the MINI, the historical sample (N = 350), assessed by chart review, consisted of consecutive patients of the same setting evaluated one year prior to the study period. Residents' perceptions were assessed by means of a focus group. Results: While in only 0.57% of the historical sample (N = 350) a diagnosis of PTSD was recorded, 20.3% (N = 64) of the patients assessed with the diagnostic instrument (N = 316) qualified for a diagnosis of PTSD. Higher prevalence rates were observed in refugees and those without legal residency status (50%); patients from countries with a recent history of war (47.1%); those with four (44.4%) or three psychiatric co-morbidities (35.3%); migrants (29.8%) and patients without professional income (25%). Residents felt that the systematic use of the tool was not adequate in the psychiatric emergency setting for various reasons (e.g.: not suitable for a first or single consultation, negative impact on the clinical evaluation). Conclusions: The study confirms that PTSD is underdiagnosed in the psychiatric emergency setting. To improve the situation, targeted screening or educational and institutional strategies are needed.

Determinants of the development of post-traumatic stress disorder, in the general population.

PURPOSE: To assess (1) the lifetime prevalence of exposure both to trauma and post-traumatic stress disorder (PTSD); (2) the risk of PTSD by type of trauma; and (3) the determinants of the development of PTSD in the community. METHODS: The Diagnostic Interview for Genetic Studies was administered to a random sample of an urban area (N = 3,691). RESULTS: (1) The lifetime prevalence estimates of exposure to trauma and PTSD were 21.0 and 5.0%; respectively, with a twice as high prevalence of PTSD in women compared to men despite a similar likelihood of exposure in the two sexes; (2) Sexual abuse was the trauma involving the highest risk of PTSD; (3) The risk of PTSD was most strongly associated with sexual abuse followed by preexisting bipolar disorder, alcohol dependence, antisocial personality, childhood separation anxiety disorder, being victim of crime, witnessing violence, Neuroticism and Problem-focused coping strategies. After adjustment for these characteristics, female sex was no longer found to be significantly associated with the risk of PTSD. CONCLUSIONS: The risk for the development of PTSD after exposure to traumatic events is associated with several factors including the type of exposure, preexisting psychopathology, personality features and coping strategies which independently contribute to the vulnerability to PTSD.

Prematurity, maternal stress and mother-child interactions.

OBJECTIVE: Previous studies have shown that premature birth and the immaturity of the child can affect the quality of the parent-child relationship. The present study examines the relationship between maternal and infant interactional behavior over time and infant perinatal risk factors as well as maternal perinatal recollected traumatic experience. Few studies have explored the relationship between maternal stress and the quality of parent-infant interaction. DESIGN: Mother-child interaction was recorded at 6 and 18 months of infant's age, in a population of 47 preterm infants (GA<34 weeks) and 25 full-term infants, born in 1998, during a play interaction. According to the Care Index, sensitivity, control and unresponsiveness have been used to code maternal interactional characteristics, and cooperation, compliance-compulsiveness, difficulty and passivity have been used to code the infant's interactional characteristics. The level of maternal stress was evaluated with the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ), and the infant's perinatal risk factors were assessed with the Perinatal Risk Inventory (PERI). RESULTS: Mothers of high-risk infants, as well as mothers that had experienced traumatic stress in the perinatal period, were less sensitive and more controlling at 6 months. The interactional behavior of the preterm infant was different from that of the full-term infant at 18 months of age, and was correlated with maternal traumatic stress but not with perinatal risk factors. CONCLUSION: These results underline the importance of maternal traumatic experience related to premature birth and its potential long lasting influence on mother-child interactional behavior.

Childhood adversities as specific contributors to the co-occurrence of posttraumatic stress and alcohol use disorders.

There is much evidence that alcohol use disorders (AUD) often co-occur with posttraumatic stress disorders (PTSD), and that the comorbid condition is associated with a more severe clinical profile than that of PTSD without AUD. However, little is known about the role of childhood adversities as specific risk factors for the development of AUD in individuals presenting with PTSD. The aim of the study was to explore whether specific stressors from the spectrum of trauma and childhood adversities contribute to the development of AUD among subjects with PTSD. From a large community sample, of N=140 individuals with PTSD, N=24 (17.14%) received an additional diagnosis of AUD with an onset after the onset of PTSD. Those with comorbid PTSD/AUD and those with PTSD only were compared regarding type and features of their trauma, childhood adversities and psychiatric comorbidity. Compared to PTSD alone, PTSD/AUD was associated with higher levels of stress in terms of childhood adversities; in particular, sexual abuse below the age of 16, but also with having been brought up in a foster home. PTSD/AUD was also associated with an earlier age of adverse events. Treatment of AUD should include standardized assessments of trauma, especially of trauma experienced during childhood.

Paranoia and post-traumatic stress disorder in the months after a physical assault: a longitudinal study examining shared and differential predictors.

Background: Being physically assaulted is known to increase the risk of the occurrence of post-traumatic stress disorder (PTSD) symptoms but it may also skew judgements about the intentions of other people. The objectives of the study were to assess paranoia and PTSD after an assault and to test whether theory-derived cognitive factors predicted the persistence of these problems. Method: At 4 weeks after hospital attendance due to an assault, 106 people were assessed on multiple symptom measures (including virtual reality) and cognitive factors from models of paranoia and PTSD. The symptom measures were repeated 3 and 6 months later. Results: Factor analysis indicated that paranoia and PTSD were distinct experiences, though positively correlated. At 4 weeks, 33% of participants met diagnostic criteria for PTSD, falling to 16% at follow-up. Of the group at the first assessment, 80% reported that since the assault they were excessively fearful of other people, which over time fell to 66%. Almost all the cognitive factors (including information-processing style during the trauma, mental defeat, qualities of unwanted memories, self-blame, negative thoughts about self, worry, safety behaviours, anomalous internal experiences and cognitive inflexibility) predicted later paranoia and PTSD, but there was little evidence of differential prediction. Conclusions: Paranoia after an assault may be common and distinguishable from PTSD but predicted by a strikingly similar range of factors.

État de stress post-traumatique comorbide, facteurs de risque et de protection parmi des individus itinérants en traitement pour des troubles liés à l’utilisation de substances

Peu d’études explorent les fréquences de traumas et d’état de stress posttraumatique (ÉSPT) chez les itinérants, spécifiquement parmi ceux avec des troubles liés à l’utilisation de substances (TUS). L’objectif principal de cette étude était de mesurer les fréquences de trauma et d’ÉSPT parmi les usagers en traitement pour des TUS à Montréal. L’autre objectif était de vérifier les différences entre ceux ayant ou non un ÉSPT. 51 individus itinérants, 9 femmes et 42 hommes, ont constitué l’échantillon. L’âge moyen était de 46 ans (SD = 7.19). Les participants ont vécu en moyenne 4.24 (SD = 2.06) types de trauma. 49% de l’échantillon avaient potentiellement un diagnostic d’ÉSPT. La majorité avait: un parent alcoolique, vécu un trauma dans l’enfance et un soutien social faible. Les participants qui avaient potentiellement un diagnostic d’ÉSPT: avaient un parent alcoolique, vécurent un trauma dans l’enfance et utilisaient davantage de stratégies de coping inadaptées.

Le blocage de la reconsolidation des souvenirs, une avenue possible pour le traitement du trouble de stress post-traumatique?

La présente thèse porte sur l’évaluation de l’efficacité d’un nouveau traitement pour le trouble de stress post-traumatique (TSPT). Le traitement a été développé selon les prémisses de la théorie de la reconsolidation des souvenirs. Il consiste en six courtes séances de remémoration de l’événement traumatique réalisées sous l’effet du propranolol, un bêtabloquant. La population de l’étude est constituée de patients souffrant d’un TSPT chronique. La thèse comporte cinq chapitres. Le premier chapitre est l’introduction, on y retrouve une description du TSPT, des traitements validés empiriquement, de diverses théories de la mémoire, d’un modèle étiologique du TSPT, d’études sur la consolidation et la reconsolidation, de la pharmacocinétique et du mécanisme d’action du propranolol,ainsi que des objectifs de la thèse. Le second chapitre est une revue critique de littérature sur la théorie de la reconsolidation. Comme l’étude du phénomène de la reconsolidation est récente, nous tentons de faire le point sur l’état des connaissances dans le domaine, dans un effort de réflexion sur la validité de la théorie. Nous proposons une série de critères permettant de différencier la reconsolidation d’autres processus connexes. Nous concluons que la théorie paraît valide, bien que d’autres études soient nécessaires afin de rendre compte de résultats négatifs publiés par le passé. Le troisième chapitre est un essai ouvert, et vise à évaluer l’efficacité d’un traitement basé sur la reconsolidation à diminuer la sévérité et l’incidence du TSPT, auprès de 42 patients souffrant d’un TSPT chronique. Le traitement consiste en six séances de remémoration de l’événement traumatique sous propranolol. Lors d’un suivi à trois mois, nous rapportons une diminution des symptômes de TSPT de 41%-56%, ainsi qu’une diminution de l’incidence du TSPT de 74%. En comparaison, seulement 2/25 patients du groupe contrôle (ayant participé uniquement aux évaluations) ne souffrent plus d’un TSPT. Dans le groupe traitement, les tailles d’effet (d de Cohen)varient entre 1.32-2.19. Le quatrième chapitre a comme objectif d’identifier des caractéristiques des patients prédisant l’efficacité du traitement, et d’explorer s’ils s’améliorent dans des domaines de santé autres que le TSPT. Nous rapportons que les femmes s’améliorent davantage que les hommes, mais que d’autres facteurs, tels que la sévérité des traits de personnalité borderline ou le type de trauma (enfance versus adulte), n’influent pas sur l’efficacité. Également, les patients s’améliorent dans les domaines de santé suivants : la qualité de vie, la symptomatologie dépressive, l’intensité des émotions négatives au rappel de l’événement traumatique et dans la vie courante. Le cinquième chapitre contient la discussion générale de la thèse. Nous effectuons une synthèse et interprétation des résultats, nous examinons les hypothèses alternatives à l’amélioration clinique et abordons des pistes de recherches futures. Nous concluons que le traitement à l’étude a été efficace dans notre échantillon de patients souffrant d’un TSPT chronique. Étant donné la méthodologie employée (essai ouvert), nous ne pouvons statuer sur le mécanisme d’action du traitement, à savoir si l’amélioration clinique a été réellement causée par un blocage de la reconsolidation des souvenirs.
