Prevalence and Significant Determinants of Post-traumatic Stress Disorder in a Large Sample of Patients with Multiple Sclerosis

Chronic and life-threatening neurodegenerative diseases may be associated with post-traumatic stress disorder (PTSD). Therefore, the current study was an investigation of the prevalence of PTSD in multiple sclerosis (MS) patients, and identification of significant determinants of PTSD. Two hundred thirty-two MS patients were consecutively recruited and screened for the presence of PTSD with the Impact of Event Scale-Revised, corroborated by the Structured Clinical Interview for DSM-IV. Furthermore, participants were administered the Hospital Anxiety and Depression Scale and the Fatigue Severity Scale. Twelve patients (12/232, i.e. 5.17 %) were diagnosed as suffering from PTSD. Levels of education, anxiety and depression were significant determinants of the presence of PTSD. The role played by the levels of education, anxiety and depression in determining the presence of PTSD has been discussed. Further research on the psychological features of neurodegenerative diseases is urgently needed in order to plan appropriate treatments and improve patients’ quality of life.     

Satisfaction profile (SAT-P) in 732 patients: Focus on subjectivity in hrqol assessment

Abstract

A 32-item questionnaire aimed at assessing patient's satisfaction about every day life is presented. In the Satisfaction Profile (SAT-P) patients are asked to evaluate their own satisfaction level on 32 daily life aspects concerning the last month. 732 participants were enrolled into the study: 490 in-patients suffering from different types of chronic diseases (e.g., chronic heart failure, severe respiratory failure, coronary heart disease) and 242 healthy persons of working age. SAT-P validity was confirmed by comparing its scores with the NHP, EPQ and STAI-X2 scores. The factor analysis extracted 5 factors which corresponded to the hypothesised areas (54% of variance explained). Test-retest reliability and internal consistency were confirmed: Pearson's coefficients were ranging from 0.45 to 0.93 and Cronbach's alpha coefficient was 0.92. SAT-P responsiveness, evaluated by comparing baseline and 6 months follow up scores from 45 chronic heart failure patients, resulted to be satisfatory, although further studies are needed. These results, together with the “user-friendly” structure, the brief administration and scoring time, the simple graphic representation, suggest to consider the SAT-P a useful complementary tool in HRQoL assessment. The Italian, English and French versions are available.     

Differentiated forgetting rates of spatial knowledge in humans in the absence of repeated testing

Spatial knowledge, necessary for efficient navigation, comprises route knowledge (memory of the landmarks along a route) and survey knowledge (map-like). Available data on the retention in humans of spatial knowledge show that this does not decline systematically over months or years. Here, two groups of participants elaborated route and survey knowledge during navigation in a complex virtual environment before performing route and survey tasks. Both groups were tested 5 minutes after learning and 3 months later, while one group was also tested 1 week and 1 month later (repeated testing). Performance was similar in both groups on the first testing session, remained stable in the repeated tested group, but decreased in the non-repeated tested group, especially on route tasks. These results are the first to reveal a substantial and selective decline of spatial knowledge, occurring only if there is no possibility of reactivating knowledge along repeated testing.     

Volunteer engagement and intention to quit from a self‐determination theory perspective

Drawing on self‐determination theory, the current study investigates the mediation process of satisfaction with the 3 basic needs (i.e., autonomy, competence, relatedness) between autonomous motivation and volunteers' turnover intention and work engagement. A study of 349 Romanian volunteers reveals an interesting dichotomy. For work engagement, the positive effect of autonomy and competence needs satisfaction appears to have been partially mediated by autonomous motivation. Turnover intention, however, was directly influenced by the degree of autonomy and competence needs satisfaction. Moreover, satisfaction of the relatedness need had no effect on the 2 outcome variables when controlling for satisfaction of autonomy and competence needs. Implications and possible explanations are suggested.     

The psychological pleasure and pain of choosing: when people prefer choosing at the cost of subsequent outcome satisfaction

This empirical investigation tested the hypothesis that the benefits of personal choosing are restricted to choices made from among attractive alternatives. Findings from vignette and laboratory studies show that contrary to people's self-predictions prior to actually choosing, choosers only proved more satisfied than nonchoosers when selecting from among more preferred alternatives. When selecting from among less preferred alternatives, nonchoosers proved more satisfied with the decision outcome than choosers. Subsequent analyses revealed that differences in outcome satisfaction between choosers and nonchoosers emerge even before the decision outcome is experienced and that interventions during the decision-making process can serve to attenuate these differences. Theoretical and practical implications are discussed.     

Teaching 'Yes' and 'No' responses to children with multiple disabilities through a program including microswitches linked to a vocal output device

The present study introduced two children (a boy and a girl of 9.2 and 12.3 yr. of age, respectively, with multiple disabilities) to an intervention program for establishing Yes and No responses in relation to preferred and nonpreferred stimuli and assessed the acquisition and generalization of those responses. The program involved the use of microswitches, which monitored the nonverbal Yes and No responses performed by the children and ensured that these responses produced the matching verbal utterances via a vocal output device. Analysis showed children acquired Yes and No responses in relation to the stimuli used for the intervention and, to a comparable degree, to the stimuli used for generalization checks as well. An interview of 30 educational staff of a center for persons with multiple disabilities indicated that they considered the presence of Yes and No verbal utterances preferable to the absence of such utterances, and thought that the utterances could be helpful for the children's response acquisition and would be useful and pleasing for staff and parents. General implications of the findings were discussed.     

What can subjective forgetting tell us about memory for childhood trauma?

In the present study, we examined the prevalence and predictors of subjective forgetting (i.e., self-reported amnesia) of child sexual abuse (CSA). Adults who, as children, were involved as victims in legal prosecutions were questioned about their CSA experiences, which had been documented in the 1980s, and about lost and recovered memory of those experiences. Males and individuals who experienced more severe abuse were more likely to report forgetting. The majority of individuals attributed their forgetting to active attempts to avoid thinking about the abuse. In contrast, when predictors of subjective forgetting were used to predict objective memory of abuse, more severe abuse and more extended legal involvement were associated with fewer memory errors. The differences between subjective and objective memory underscore the risks of using subjective measures to assess lost memory of abuse.     

Traumatic impact predicts long-term memory for documented child sexual abuse

Prospective studies of adults' memories of documented child sexual abuse (CSA) reveal that the majority of individuals remember their victimization. However, the accuracy of these memories has rarely been investigated scientifically. The present study examined predictors of memory accuracy and errors 12 to 21 years after abuse ended for individuals with legal experiences resulting from documented CSA. Severity of posttraumatic stress disorder (PTSD) symptomatology was positively associated with memory accuracy. However, individuals nominating CSA as their most traumatic life event exhibited relatively accurate memory regardless of indicators of PTSD. Predictors of memory errors were also identified (e.g., less maternal support). These results indicate that, in addition to understanding the role of traditional cognitive factors, understanding an event's traumatic impact is important for predicting the accuracy of long-term memory for reported CSA.     

Gender and lexical access in Italian

Two new procedures were employed to investigate the effects of semantic and grammatical gender on lexical access in Italian and to investigate the interaction of gender with other factors that are known to influence lexical access in other languages. The gender-monitoring task requires a conscious decision about the gender of each noun, whereas the word repetition task does not require explicit attention to gender. In both tasks, single words are presented out of context, under speeded conditions. Both procedures proved to be sensitive indices of word recognition, with reaction times that are closely tied to the point at which words can be uniquely identified (although some processing before and after the uniqueness point was seen). In both tasks, reaction times were strongly affected by phonological factors (e.g., length, number of syllables, and presence of frication on the initial consonant). Phonological transparency of gender marking had a reliable effect on gender monitoring but had no effect on word repetition, suggesting that explicit attention to gender may be a factor affecting utilization of this phonological cue. Semantic factors (including semantic gender) had no effect on performance. Frequency and age of acquisition had very small effects when other factors were controlled. Implications for current models of lexical access are discussed, with special reference to the role of gender.     

Effect of Grammatical Gender and Semantic Context on Lexical Access in Italian

The interacting effects of sentence context and grammatical gender on lexical access were investigated in Italian using a timed picture-naming paradigm. Results snowed large interacting effects of both sentence context and the gender of the article, with facilitation relative to two different control conditions. Repeat testing yielded an overall decrease in RT, but did not change the pattern of results. Results are interpreted in support of interactive activation models in which different sources of information are combined on-line to predict, anticipate or preactivate lexical targets.
