La sintomatologia ansiosa materna nel periodo prenatale risulta influire negativamente non sullo stato materno ma anche sul successivo sviluppo infantile, Tuttavia, sono limitati gli studi che hanno considerato lo specifico contributo dei disturbi d’ansia nel periodo prenatale. L’obiettivo generale dello studio è quello di indagare nel primo periodo post partum la relazione tra psicopatologia ansiosa materna e: temperamento e sviluppo neonatale, qualità del caregiving materno e dei pattern interattivi madre-bambino. 138 donne sono state intervistate utilizzando SCID-I (First et al., 1997) durante il terzo trimestre di gravidanza. 31 donne (22,5%) presentano disturbo d’ansia nel periodo prenatale. A 1 mese post partum il comportamento del neonato è stato valutato mediante NBAS (Brazelton, Nugent, 1995), mentre le madri hanno compilato MBAS (Brazelton, Nugent, 1995). A 3 mesi postpartum, una sequenza interattiva madre-bambino è stata videoregistrata e codificata utilizzando GRS (Murray et al., 1996). La procedura dello Stranger Episode (Murray et al., 2007) è stata utilizzata per osservare i pattern interattivi materni e infantili nell’interazione con una persona estranea. I neonati di madri con disturbo d’ansia manifestano alle NBAS minori capacità a livello di organizzazione di stati comportamentali, minori capacità attentive e di autoregolazione. Le madri ansiose si percepiscono significativamente meno sicure nell’occuparsi di loro, valutando i propri figli maggiormente instabili e irregolari. Nell’interazione face to face, esse mostrano comportamenti significativamente meno sensibilI, risultando meno coinvolte attivamente con il proprio bambino. Durante lo Stranger Episode, le madri con fobia sociale presentano maggiori livelli di ansia e incoraggiando in modo significativamente inferiore l’interazione del bambino con l’estraneo. I risultati sottolineano l’importanza di valutare in epoca prenatale la psicopatologia ansiosa materna. Le evidenze confermano la rilevanza che può assumere un modello multifattoriale di rischio in cui i disturbi d’ansia prenatali e la qualità del caregiving materno possono agire in modo sinergico nell’influire sugli esiti infantili. / Maternal antenatal anxiety has been shown to be associated with adverse consequences for the mother and the child. However, studies considering the effect of DSM-IV anxiety disorders during pregnancy are lacking. The general aim was to investigate, in the early postpartum, the relationship between maternal prenatal anxiety psychopathology and: neonatal behavioral development, quality of caregiving, maternal and infant’s interactive behaviors. 138 women completed the clinical interview SCID-I for DSM-IV (First et al., 1997) during the third trimester of pregnancy to assess anxiety disorders. 31 women (21,5%) showed an anxiety disorders during antenatal period. At one month postpartum, the neonatal development was assessed using NBAS (Brazelton, Nugent, 1995) and the mothers completed the MBAS (Brazelton, Nugent, 1995). At 3 months postpartum, mother-infant interactions were video-recorded and coded using GRS (Murray et al., 1996). Stranger Episode procedure (Murray et al., 2007) was used to assess maternal and infant’s interactive pattern with an unfamiliar person. Anxious mothers’ babies had poorer performances on NBAS regarding attention, self-quieting, examiner facilitation, state regulation (p<0.05). Anxious mothers perceived themselves as having a greater lack of confidence in caretaking and they consider their babies as more unsettled-irregular (p<0.05). Mothers with anxiety disorder showed less sensitive interactive behavior, resulting more withdrawal and less engaged with their infants than controls. During Stranger Episode, mothers with social phobia appeared more anxious, engaged less with the stranger themselves, and were less encouraging of the infant’s interaction with an unfamiliar person. Results underline the importance of assessing and monitoring maternal antenatal anxiety. These findings are consistent with a cumulative risk model suggesting that maternal prenatal anxiety and quality of maternal caregiving could act in concert to shape infant outcomes.

Psi is the phenomenon of apparently responding to or receiving information by means other than the recognised senses. Psi information may influence human behaviour, without the individual intending this or even being aware of it. This thesis seeks to investigate nonintentional behavioural responses to psi. We present five empirical studies that investigated nonintentional behavioural responses to psi information. In each study, the psi information was hidden from participants, in that the participants neither had sensory access to it, nor did they know that it existed. Two different combinations of psi information and a behavioural response were examined. The first was the influence of hidden psi information on psychological task performance. The second was the influence of covert, remote observation by hidden observers on the social facilitation effect. In all the studies, the effects of individual differences in participants’ personalities were also considered. In Experiment 1 we investigated whether hidden targets influenced participants’ judgements of the lengths of lines. There was no overall psi effect, but we found a replication of a response bias effect and a significant correlation between psi and participants’ extraversion. In Experiment 2 we investigated whether hidden targets influenced participants’ speed on a maths task. There was no overall psi effect and no correlations between personality and psi scores. We reviewed previous research literature on social facilitation from the novel angle of investigating whether being watched can, in and of itself, lead to the social facilitation effect. Experiments 3, 4, and 5 developed the paradigm of testing for a social facilitation effect from remote observation, investigating whether remote observation leads to the same behavioural changes as knowingly being observed by a physically present person. We compared participants’ performance on psychological tasks under different observation conditions: alone, remotely observed by a hidden observer, and observed by a physically present observer. The expected social facilitation effect was not found in these experiments, leading to a series of improvements to the sampling, methodology, and tasks over the course of these experiments. As the social facilitation effect from a physically present observer was not reliably replicated, these experiments were not conclusive tests of whether there is a social facilitation effect from remote observation. However, there was an indication in Experiment 3 that remote observation does not exert a significant behavioural effect. Considered together, our studies explored novel approaches to examining nonintentional behavioural responses to psi. The significant correlation between participants’ extraversion and psi is, to our knowledge, the first time this effect has been found in a nonintentional psi experiment. This, and the replication of the response bias effect, represent important advances in parapsychology. Our experiments are also the first to test the assumption, inherent in many research designs, that covert observation does not affect participants’ behaviour. Overall, our findings did not support the psi hypothesis.

The aim of this investigation was to explore the nature and the severity of circadian abnormalities and attentional deficit in type 1 narcolepsy. In three studies, narcolepsy patients were compared with patients suffering from other central disorders of hypersomnolence and healthy controls on attentional functions and circadian rhythms. Study 1 evaluated the sensibility of actigraphic monitoring in distinguishing the features of daytime and nighttime sleep between adult patients with type 1 Narcolepsy, Idiopathic Hypersomnia and healthy controls. Actigraphy provides a reliable assessment of sleep quality and daytime napping behavior able to distinguish central disorders of hypersomnolence and identify Narcolepsy Type 1 patients. Study 2 describes the features of circadian activity rhythm of narcolepsy type 1 children with recent disease onset. Type 1 narcolepsy children and healthy children were monitored for seven days during the school week, circadian activity rhythms were analyzed through functional linear modeling. Children with type 1 narcolepsy present an altered rest-activity rhythm characterized by enhanced motor activity throughout the night and blunted activity in the first afternoon. The observation of a discrete circadian profile provides new insight on the nature of diurnal variations and suggested that the quantitative assessment of motor activity is a promising behavioral biomarker of Type 1 narcolepsy. The aim of Study 3 was to explore the nature and the severity of attentional Deficits of Narcoleptic patients. This study examined whether narcoleptic patients would exhibit impairments in alerting, orienting, and executive control of attention relative to healthy controls. Narcoleptic patients present a deficit in alerting network, while orienting and executive control networks resulted preserved. Moreover the alerting network efficiency significantly correlate with levels of subjective sleepiness. Results indicates that in narcolepsy the unstable tonic component of alerting process make necessary monitoring and compensation strategies.

Il presente lavoro comincia con una descrizione dettagliata del “McMaster Model of Family Functionig” (MMFF), modello che al suo interno integra una teoria multidimensionale sul funzionamento familiare, diversi strumenti di auto ed etero valutazione e chiare indicazioni terapeutiche racchiuse all’interno della “Problem Centered System Therapy of the Family” (PCSTF). Grazie alla sua completezza il Modello fornisce ai clinici metodi coerenti, pratici ed empiricamente validi per valutare e trattare le famiglie, essi inoltre, sono stati formulati in modo da essere adattabili a differenti setting clinici e di ricerca, applicabili ad un’ampia gamma di problematiche e verificabili empiricamente. Obiettivo finale della presente ricerca è stato quello di porre le basi per l’esportazione del MMFF in Italia e poter quindi procedere alla sua applicazione in ambito clinico. La ricerca è cominciata alla Brown University con la traduzione dall’inglese all’italiano del Family Assessment Device (FAD), uno degli strumenti di autovalutazione compresi nel MMFF, ed è in seguito continuata con la validazione del suddetto strumento in un campione di 317 soggetti appartenenti alla popolazione generale italiana. Il FAD si è dimostrato uno strumento valido ed affidabile, in grado quindi di fornire valutazioni stabili e coerenti anche nella sua versione italiana. Il passo successivo è stato caratterizzato dalla somministrazione di FAD, Symptom Questionnaire (SQ) e delle Psychological Well-Being scales (PWB) a 289 soggetti reclutati nella popolazione generale. In accordo con il modello bipsicosociale che vede l’ambiente familiare come il più immediato gruppo di influenza psicosociale dello stato di benessere o malessere dell’individuo, i nostri dati confermano una stretta relazione tra scarso funzionamento familiare, spesso espresso attraverso difficoltà di comunicazione, di problem solving e scarso coinvolgimento affettivo e distress psicologico esperito con sintomi depressivi, ansiogeni ed ostilità. I nostri dati sottoliano inoltre come un funzionamento familiare positivo sia altamente correlato ad elevati livelli di benessere psicologico. Obiettivo della parte finale del lavoro ed anche il più importante, è stato quello di esplorare l’efficacia della Problem Centered Systems Therapy of the Family nella gestione della perdita di efficacia degli antidepressivi nel trattamento della depressione ricorrente. 20 soggetti con diagnosi di depressione maggiore ricorrente secondo il DSM-IV sono stati randomizzati a due diverse condizioni di trattamento: 1) aumento del dosaggio dell’antidepressivo e clinical management, oppure 2) mantenimento dello stesso dosaggio di antidepressivo e PCSTF. I dati di questo studio mettono in evidenza come, nel breve termine, PCSTF e farmacoterapia sono ugualmente efficaci nel ridurre la sintomatologia depressiva. Diversamente, ad un follow-up di 12 mesi, la PCSTF si è dimostrata altamente superiore all’aumento del farmaco ner prevenire le ricadute. Nel gruppo sottoposto all’aumento del farmaco infatti ben 6 soggetti su 7 ricadono entro l’anno. Nel gruppo assegnato a terapia familiare invece solo 1 soggetto su 7 ricade. Questi risultati sono in linea con i dati della letteratura che sottolineano l’elevata probabilità di una seconda ricaduta dopo l’aumento dell’antidepressivo all’interno di una farmacoterapia di mantenimento e suggeriscono l’efficacia dell’utilizzo di strategie psicoterapiche nella prevenzione della ricaduta in pazienti con depressione ricorrente.

Objectives: The aim of this research was to evaluate the impact of Cardiac Rehabilitation (CR) on risky lifestyles, quality of life, psychopathology, psychological distress and well-being, considering the potential moderating role of depression, anxiety and psychosomatic syndromes on lifestyles modification. The influence of CR on cardiac morbidity and mortality was also evaluated. Methods: The experimental group (N=108), undergoing CR, was compared to a control group (N=85) of patients affected by cardiovascular diseases, not undergoing CR, at baseline and at 1-month, 6- and 12-months follow-ups. The assessment included: the Structured Clinical Interview for DSM-IV, the structured interview based on Diagnostic Criteria for Psychosomatic Research (DCPR), GOSPEL questionnaire on lifestyles, Pittsburgh Sleep Quality Index, Morisky Medication Adherence Scale, MOS 36-Item Short Form Health Survey, Symptom Questionnaire, Psychological Well-Being Scale and 14-items Type D Scale. Results: Compared to the control group, CR was associated to: maintenance of the level of physical activity, improvement of correct dietary behaviors and stress management, enhancement of quality of life and sleep; reduction of the most frequently observed psychiatric diagnoses and psychosomatic syndromes at baseline. On the contrary, CR was not found to be associated with: healthy dietary habits, weight loss and improvement on medications adherence. In addition, there were no relevant effects on sub-clinical psychological distress and well-being, except for personal growth and purpose in life (PWB). Also, CR did not seem to play a protective role against cardiac recurrences. The presence of psychosomatic syndromes and depressive disorders was a mediating factor on the modification of specific lifestyles. Conclusions: The findings highlight the need of a psychosomatic assessment and an evaluation of psychological sub-clinical symptomatology in cardiac rehabilitation, in order to identify and address specific factors potentially associated with the clinical course of the heart disease. / Obiettivi: Lo scopo della presente tesi di dottorato è stato valutare l’impatto della Riabilitazione Cardiologica (RC) sulla modificazione di stili di vita, qualità di vita, psicopatologia, distress e benessere psicologico, considerando il possibile effetto moderatore di disturbi depressivi, ansiosi e sindromi psicosomatiche sul cambiamento degli stili di vita. È stata inoltre valutata l’influenza della RC su morbilità e mortalità cardiaca. Metodi: Il gruppo sperimentale (N=108), sottoposto a RC, è stato confrontato con un gruppo di controllo (N=85), composto da pazienti cardiopatici non sottoposti a RC, sia alla baseline che a 1 mese, 6 e 12 mesi. L’assessment ha incluso: la Structured Clinical Interview for DSM-IV, l’intervista strutturata basata sui Diagnostic Criteria for Psychosomatic Research (DCPR), il questionario GOSPEL sugli stili di vita, il Pittsburgh Sleep Quality Index, la Morisky Medication Adherence Scale, il MOS 36-Item Short Form Health Survey, il Symptom Questionnaire, la Psychological Well-Being Scale e la 14-items Type D Scale. Risultati: La RC, rispetto alla condizione di controllo, è risultata associata a: mantenimento dei livelli di attività fisica, aumento dei comportamenti alimentari corretti e della capacità di gestione dello stress, miglioramento della qualità di vita e del sonno; diminuzione delle diagnosi psichiatriche e psicosomatiche più frequentemente riscontrate alla baseline. Al contrario, non è risultata associata a: stile alimentare sano, perdita di peso e miglioramento dell’aderenza farmacologica. Inoltre, non sono stati riscontrati effetti rilevanti riguardo a benessere e distress psicologico sub-clinico, fatta eccezione per la crescita personale e lo scopo nella vita (PWB). La RC non ha inoltre svolto un ruolo protettivo sul decorso clinico. La presenza di sindromi psicosomatiche e disturbi depressivi ha influenzato l’andamento di specifici stili di vita. Conclusioni: I risultati evidenziano l’importanza di una valutazione psicologica integrata in riabilitazione cardiologica, allo scopo di identificare e gestire fattori potenzialmente associati al decorso clinico della patologia cardiaca.

Background: It is well known, since the pioneristic observation by Jenkins and Dallenbach (Am J Psychol 1924;35:605-12), that a period of sleep provides a specific advantage for the consolidation of newly acquired informations. Recent research about the possible enhancing effect of sleep on memory consolidation has focused on procedural memory (part of non-declarative memory system, according to Squire’s taxonomy), as it appears the memory sub-system for which the available data are more consistent. The acquisition of a procedural skill follows a typical time course, consisting in a substantial practice-dependent learning followed by a slow, off-line improvement. Sleep seems to play a critical role in promoting the process of slow learning, by consolidating memory traces and making them more stable and resistant to interferences. If sleep is critical for the consolidation of a procedural skill, then an alteration of the organization of sleep should result in a less effective consolidation, and therefore in a reduced memory performance. Such alteration can be experimentally induced, as in a deprivation protocol, or it can be naturally observed in some sleep disorders as, for example, in narcolepsy. In this research, a group of narcoleptic patients, and a group of matched healthy controls, were tested in two different procedural abilities, in order to better define the size and time course of sleep contribution to memory consolidation. Experimental Procedure: A Texture Discrimination Task (Karni & Sagi, Nature 1993;365:250-2) and a Finger Tapping Task (Walker et al., Neuron 2002;35:205-11) were administered to two indipendent samples of drug-naive patients with first-diagnosed narcolepsy with cataplexy (International Classification of Sleep Disorder 2nd ed., 2005), and two samples of matched healthy controls. In the Texture Discrimination task, subjects (n=22) had to learn to recognize a complex visual array on the screen of a personal computer, while in the Finger Tapping task (n=14) they had to press a numeric sequence on a standard keyboard, as quickly and accurately as possible. Three subsequent experimental sessions were scheduled for each partecipant, namely a training session, a first retrieval session the next day, and a second retrieval session one week later. To test for possible circadian effects on learning, half of the subjects performed the training session at 11 a.m. and half at 17 p.m. Performance at training session was taken as a measure of the practice-dependent learning, while performance of subsequent sessions were taken as a measure of the consolidation level achieved respectively after one and seven nights of sleep. Between training and first retrieval session, all participants spent a night in a sleep laboratory and underwent a polygraphic recording. Results and Discussion: In both experimental tasks, while healthy controls improved their performance after one night of undisturbed sleep, narcoleptic patients showed a non statistically significant learning. Despite this, at the second retrieval session either healthy controls and narcoleptics improved their skills. Narcoleptics improved relatively more than controls between first and second retrieval session in the texture discrimination ability, while their performance remained largely lower in the motor (FTT) ability. Sleep parameters showed a grater fragmentation in the sleep of the pathological group, and a different distribution of Stage 1 and 2 NREM sleep in the two groups, being thus consistent with the hypothesis of a lower consolidation power of sleep in narcoleptic patients. Moreover, REM density of the first part of the night of healthy subjects showed a significant correlation with the amount of improvement achieved at the first retrieval session in TDT task, supporting the hypothesis that REM sleep plays an important role in the consolidation of visuo-perceptual skills. Taken together, these results speak in favor of a slower, rather than lower consolidation of procedural skills in narcoleptic patients. Finally, an explanation of the results, based on the possible role of sleep in contrasting the interference provided by task repetition is proposed.

Extensive literature outlined that the quality of the mother-foetus relationship is considered the main feature with regard to the quality of postnatal mother-infant interaction and also to the child’s psychical development. Nowadays the relationship between the pregnant woman and her foetus is viewed as the central factor of the somatic dialogue between the functioning of the maternal and the foetal organisms. This dialogue is responsible for the physic development of the child, as well as of its psychosomatic structure. Therefore the research area has necessarily had to extend to the analysis of psychological processes concerning: the pregnancy, the couple that is bound by parenthood, the influence of intergenerational dynamics. In fact, the formation of maternal identity, as well as that of the relationship between the woman and the foetus, refers to the pregnant woman’s relationship with her parents, especially with her mother. The same pregnancy, considered as a psychosomatic event, is directly influenced by relational, affective and social factors, particularly by the quality of the interiorized parental relations and the quality of the current relationships (such as that with her partner and with her family of origin). Some studies have begun to investigate the relationship between the pregnant woman and the foetus in term of “prenatal attachment” and its relationship with socio-demographic, psychological e psychopathological aspects (such as pre and post partum depression), but the research area is still largely unexplored. The present longitudinal research aimed to investigate the quality of the pregnant womanfoetus relationship by the prenatal attachment index, the quality of the interiorized relationship with woman’s parents, the level of alexithymic features and maternity social support, in relation with the modulation of the physiology of delivery and of postpartum, as well as of the physical development of the child. A consecutive sample of 62 Italian primipara women without any kind of pathologies, participated in the longitudinal study. In the first phase of this study (third trimester of the pregnancy), it has investigated the psychological processes connected to the affective investment of the pregnant women towards the unborn baby (by Prenatal Attachment Inventory), the mothers’ interiorized relationship with their own parents (by Parental Bonding Instrument), the social and affective support from their partner and their family of origin are able to supply (by Maternity Social Support Scale), and the level of alexithymia (by 20-Toronto Alexithymia Scale). In the second phase of this study, some data concerning the childbirth course carried out from a “deliverygram” (such as labour, induction durations and modalities of delivery) and data relative to the newborns state of well-being (such as Apgar and pH indexes). Finally, in the third phase of the study women have been telephoned a month after the childbirth. The semistructured interview investigated the following areas: the memory concerning the delivery, the return to home, the first interactions between the mother and the newborn, the breastfeeding, the biological rhythms achieved from newborns. From the data analysis a sample with a good level of prenatal attachment and of support social and a good capability to mental functioning emerged. An interesting result is that the most of the women have a great percentage of “affectionless control style” with both parents, but data is not sufficient to interpret this result. Moreover, considering the data relative to the delivery, medical and welfare procedures, that have been necessary, are coherent with the Italian mean, while the percentage of the caesarean section (12.9%) is inferior to the national percentage (30%). The 29% of vaginal partum has got epidural analgesia, which explains the high number (37%) of obstetrician operations (such as Kristeller). The data relative to the newborn (22 male, 40 female) indicates a good state of well-being because Apgar and pH indexes are superior to 7 at first and fifth minutes. Concerning the prenatal phase, correlation analysis showed that: the prenatal attachment scores positively correlated with the expected social support and negatively correlated with the “externally oriented thinking” dimension of alexithymia; the maternity social support negatively correlated with total alexithymia score, particularly with the “externally oriented thinking” dimension, and negatively correlated with maternal control of parental bonding. Concerning the delivery data, there are many correlations (after all obvious) among themselves. The most important are that the labour duration negatively correlated with the newborn’s index state of well-being. Finally, concerning the data from the postpartum phase the women’ assessments relative to the partum negatively correlated with the duration of the delivery and positively correlated with the assessment relative to the return to home and the interaction with the newborn. Moreover the length of permanence in the hospital negatively correlated with women’s assessments relative to the return to home that, in turn, positively correlated with the quality of breastfeeding, the interaction between the mother and the newborn and the biological regulation of the child. Finally, the women’ assessments relative to breastfeeding positively correlated with the mother-child interactions and the biological rhythms of children. From the correlation analysis between the variables of the prenatal phase and the data relative to the delivery, emerged that the prenatal attachment scores positively correlated with the dilatation stage scores and with the newborn’s Apgar index at first minute, the paternal care dimension of parental bonding positively correlated with the lengths of the various periods of childbirth like so the paternal control dimension with placental stage. Moreover, emerged that the expected social support positively correlated with the lengths of the various periods of childbirth and that the global alexithymia scores, particularly “difficulty to describe emotions” dimension, negatively correlated with total childbirth scores. From the correlation analysis between the variables of the prenatal phase and variable of the postpartum phase emerged that the total alexithymia scores positively correlated with the time elapsed from the childbirth to the breastfeeding of the child, the difficulty to describe emotions dimension of the alexithymia negatively correlated with the quality of the breastfeeding, the “externally oriented thinking” dimension of the alexithymia negatively correlated with mother-child interactions, and finally the paternal control dimension of the parental bonding negatively correlated with the time elapsed from the child to the breastfeeding of the child. Finally, from the analysis of the correlation between the data of the partum and the women’s assessments of the postpartum phase, emerged the negative correlation between the woman’s assessment relative to the delivery and the quantitative of obstetrician operations and the lengths of the various periods of childbirth, the positive correlation between the women’s assessment about the length of delivery periods and the real lengths of the same ones, the positive relation between woman’s assessment relative to the delivery and the Apgar index of children. In conclusion, there is a remarkable relation between the quality of the relationship the woman establishes with the foetus that influences the course of the pregnancy and the delivery that, in turn, influences the postpartum outcome, particularly relative to the mother-children relationship. Such data should be confirmed by heterogeneous populations in order to identify vulnerable women and to project focused intervention.
