Depressive symptoms and academic self-image in adolescence.

The aim of this paper was to specifically analyse the relationship between the different components of academic self-image, defined as the way adolescents represent themselves as students, and self-reported depressive symptoms, assessed with the Children's Depression Inventory (CDI), in a non-clinical sample of 298 adolescents. We considered both adolescents' beliefs about their own cognitive functioning in academic performance and beliefs about their emotional attitude in achievement situations. Our data indicate that the pattern of correlation between emotional beliefs about schooling and learning are significantly related to CDI scores, but this correlation is not evident for the cognitive beliefs. This pattern of correlation is affected by actual school functioning, because correlation between CDI and beliefs is much more significant in subjects without school failure. Differences between gender in CDI scores, beliefs about schooling and learning, and pattern of correlation are considered. These results can enable to focus supporting psychological interventions on more specific targets.

Cattell's 16 PF and PSY inventory: relationship between personality traits and behavioral responses in patients with acute myocardial infarction.

The aim of this study was to investigate the relationships between personality and behavioral responses in patients with acute myocardial infarction. In a first step, a new instrument (PSY Inventory) for assessment of six behavioral characteristics (Sense of Responsibility, Energy and Competitiveness, Obsessive Behavior, Anger and Hostility, Stress-related Disturbances, Time Urgency) was developed by using factor analysis on intercorrelations of responses from 524 subjects of the general population. Internal consistency reliability for each of the PSY subscales was estimated by Cronbach alpha coefficients. In a second step, the PSY Inventory was administered with the Cattell 16 PF Questionnaire to 838 patients affected by acute myocardial infarction. Significant correlations although relatively low in magnitude for PSY Inventory subscales and certain scales of the Cattell 16 PF were found. With factor analysis on 22 variables (including the six PSY Inventory subscales and the 16 scales of the Cattell 16 PF), five second-order factors were identified, namely, Extraversion, Neurotic Anxiety, Superego Strength, Pathemia, and Neurotic Hostility. While a Pathemia Factor (characterized by sensitivity, imagination, and self-sufficiency) was factorially independent of scales of the PSY Inventory, Extraversion, Neurotic Anxiety, Superego Strength, and Neurotic Hostility Factors were composed of the PSY Inventory scales and Cattell 16 PF scales combined. These relationships would reflect the concordance of internal constructs for behavioral measures of the PSY Inventory and those of personality traits of the 16 PF Questionnaire in patients with acute myocardial infarction.

Physiological response in healthy subjects and in patients after myocardial infarction, elicited by a new computerised version of the Raven Coloured PM 47 as a mental stress test.

The Raven Progressive Matrices Test, in its various versions, has frequently been used in research on stress related diseases. In this paper the preliminary data relating to the administration of this version of test performed by a personal computer are presented. The "Coloured" version of the PM 47 was used, with the addition of a series of visual and acoustic stress stimuli; a maximum 30-second matrix presentation time was also introduced. Two groups took part in the test modified in this way: the first was made up of 23 male subjects aged 30 to 65 who had had a myocardial infarction in the previous six months; the second, a control group of the first, was composed of an equal number of subjects, without present or past cardiovascular or psychiatric disorders or illness. Frontal EMG, skin conductance response, peripheral temperature, heart rate and respiration rate were recorded at rest and during the test administration. The results obtained from the psychophysiological profile carried out on the two groups demonstrated the effectiveness of the methodology used in eliciting constant and stable stress responses.

Subclinical hypothyroidism: neurobehavioral features and beneficial effect of L-thyroxine treatment.

Frank hypothyroidism is known to induce neurological and mental dysfunction. The aim of this study was to assess selected neuropsychological and behavioral features by means of standardized tests in a group of 14 patients with subclinical hypothyroidism who were free from neuropsychological complaints and to evaluate the possible effects of L-thyroxine treatment on their performance. Patients were submitted to the Crown and Crisp Experiential Index and to the Wechsler Memory Scale; their ratings on the neurobehavioral tests and their thyroid hormone profile were compared to those of a control group of 50 age- and sex-matched subjects. Comparison was also carried out between pretreatment ratings and those obtained following a 6-month L-thyroxine course (0.1-0.15 mg/day). The Wechsler Memory Scale ratings showed a significant impairment in patients' memory-related abilities [memory quotient (MQ) = 89.1 +/- 2.9; P = 0.002 (patients versus controls)]; the Crown and Crisp Experiential Index ratings demonstrated moderate differences between untreated patients and controls with respect to hysteria (P = 0.03), anxiety (P = 0.05), somatic complaints (P = 0.0005), and depressive features (P = 0.002) scales; the total score was also significantly higher (42.0 +/- 3.8; P = 0.005). After L-thyroxine treatment the patients' performances showed an improvement in memory skills, as evaluated by the Wechsler Memory Scale [MQ = 99.9 +/- 4.0; P = 0.002 (treated versus untreated)]; somatic complaints (P = 0.02) and obsessionality (P = 0.04) ratings and the Crown and Crisp Experiential Index total score (P = 0.04) significantly decreased with respect to untreated patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[The type of coma as prognostic indicator in severe cranial trauma in childhood]. / Il tipo di coma quale indicatore prognostico nei gravi traumi cranici in età evolutiva.

Various methods are used by neurologists to evaluate posttraumatic brain damage. The most important and reliable are the length of posttraumatic amnesia and coma. In previous papers we have already described the value of the type of coma in the prognosis of serious head injury in childhood (Baracchini-Muratorio et al. 1985; Pruneti et al. 1985). In this study, 30 children (aged 6-12 years) with serious closed head injury and subsequent coma were evaluated. The children were divided into two groups according to the type of coma, using the Plum and Posner coma classification (1966) modified by Pagni et al. (1974). The children were followed up for at least two years (9 for five years) after the trauma by means of neurological, physical, EEG, CT scan and neuropsychological examinations. The neuropsychological test results confirm the hypothesis of a different evolution of sequelae in relation to the type of coma, independently of length of coma and site of brain damage.

[Preclinical hypothyroidism: early involvement of memory function, behavioral responsiveness and myocardial contractility]. / Ipotiroidismo preclinico: precoce interessamento delle funzioni mnestiche, della reattività comportamentale e della contrattilità cardiaca.

Subclinical hypothyroidism in characterized by elevated TSH levels in the face of normal thyroid hormone concentrations. The purpose of this study was to evaluate whether these subjects show alterations of neuropsychological and behavioural features and of myocardial contractility as patients with overt hypothyroidism do. We evaluated in 14 subjects the hormonal profile (total and free T3 and T4, TSH), memory ability (Wechsler Memory Scale), behavioural reactivity (Crown & Crisp Experimental Index) and the pre-ejection period (isometric systole). We found an evident impairment of some cognitive functions correlated to memory and a behavioural alteration, perhaps secondary to the disease state, and moreover an early defect of myocardial contractility, represented by prolonged pre-ejection period. These results suggest that these patients should be treated with adequate doses of L-Thyroxine, like in overt hypothyroidism.

Behavioral treatment of children after severe head injury: a pilot study.

Little has been written on the treatment of cognitive and behavioral disorders in children following serious head injuries with coma. We have used the behavioral modification method known as Token Economy in 20 head-injured patients having a mean age of 11 years. The treatment, which involved the children's families, proved at one-year follow-up to be highly successful in normalizing maladaptive behavior.

[Audiological and neuropsychological development study in a sample of school children from a low-iodine area of the Central Apennines that is endemic for cretinism]. / Studio audiologico e dello sviluppo neuropsichico in un campione di scolari di un'area a basso apporto iodico dell'Appennino Centrale con cretinismo endemico.

We have evaluated neuropsychic development in 70 normal schoolchildren in an area of severe endemic goitre and cretinism in the Central Apennines (Montefeltro). In each subject we have studied auxological, psychometric and audiometric parameters, together with tympanograms and stapedial reflexograms. Auxological data were in the normal range, as were the stapedial reflexograms and tympanograms. On the contrary, 54.8% of the sample performed below the 25th percentile in psychometric tests (Raven test PM-47), being also 22.8% below the 5th percentile. Audiometric data showed a neurological hearing impairment in 3.1% of the children tested, as compared with 0.28% in the area of Pisa. These data point out that an impairment of central nervous system function still persists in this area of severe endemic goitre.

Clinical characteristics of anginal pain in man.

The clinical recognition of the cardiac origin of chest pain or discomfort on the basis of the description made by the patient, is often difficult. Nevertheless, considering the importance of the correct diagnosis of such syndrome, much work has been done in this field. In this report we will comment data from the literature and from our own, on the quality, duration, irradiation and on the precipitating or relieving factors that are more frequently associated with anginal pain.

Neuropsychological sequelae after head injury with mesencephalic coma in childhood.

Eleven children aging between 4 years 11 months and 12 years 6 months were examined periodically over five years following closed head injury with mesencephalic coma (Plum and Posner's definition). It was found that although transient sequelae (neurological and cognitive) on coma resolution were severe, long-term recovery was generally good. The subjects had drug, neurological and psychological treatment during the 2-5-years period and showed apparently better recovery than reported in literature for trauma in adults. This suggests that the mildly controversial "age" variable is highly important in long-term prognosis of impairments following head injury. Further studies will be necessary; with the systematic use of the same standardised testing procedures in all studies, we suggest to obviate the problems in collation arising from discrepancies in methodological, neurological and psychological techniques.
