Prolonged Social Withdrawal During Adolescence: Transdiagnostic Syndrome or a New Psychiatric Entity?

The Japanese term Hikikomori is used to describe a clinical condition in which young people present a prolonged social withdrawal and isolation. Hikikomori syndrome represents an emergent worldwide phenomenon but is still poorly reported and often misdiagnosed. This study investigates and describes an Italian hikikomori adolescent group. Socio-demographic and psychopathological profiles and the relationship between hikikomori and psychopathological conditions were analyzed. No gender difference, a medium-high intellectual level, and no correlation with socioeconomic status were highlighted among the clinical group. The relationship between social withdrawal and social anxiety was significant while no correlation was found with depressive symptoms. The presence of Hikikomori syndrome was also significant in Italian adolescents, suggesting that hikikomori is not a culture-bound syndrome related to the Japanese cultural context, but rather a syndrome occurring in the upper-medium class.

The Cognitive Profile of Gifted Children Compared to Those of Their Parents: A Descriptive Study Using the Wechsler Scales.

The manifestation of performance at the top of a given talent distribution constitutes giftedness. While identifying talented youths based on IQ has been the focus of previous research, examining their cognitive profile is a new endeavor. The present study assessed the IQ and cognitive abilities of a sample of gifted Italian children and compared them to their parents using the Wechsler scales. Fifty-nine gifted children aged 6 to 14 years were administered the WISC-IV while their parents (N = 53 mothers and N = 55 fathers) took the WAIS-IV. The gifted children (IQ ≥ 120) obtained particularly high scores in verbal comprehension (VCI) and visual-perceptual reasoning (PRI). More than two-thirds of the mothers and over half of the fathers also achieved an IQ ≥ 120. The gifted children scored significantly higher than both mothers and fathers in VCI and PRI. The mothers were significantly higher than their children in the processing speed domain. Correlational analyses highlighted that children's IQ was positively related to that of their mothers. In keeping with the literature, the cognitive profile of gifted children was found to vary across cognitive abilities. It follows that the General Ability Index was the WISC-IV index that best matched the potential of gifted youths. Consistent with previous research, our study suggests that intellectual abilities, especially working memory and processing speed, are maintained and presumably passed on from one generation to the next.

The Floor Effect on the ABAS-II in Adolescents with Autism Spectrum Disorder.

The present study aimed at enhancing the assessment of adaptive behavior in adolescents with Autism Spectrum Disorder trough the Adaptive Behavior Assessment System-Second Edition. To overcome the limits underpinning floor effect, which are commonly observed with the traditional methods, the statistical Hessl method and its revision by Orsini, Pezzuti and Hulbert was adopted. The results showed a more variation using the former method compared to the latter: a greater impairment in Social versus Leisure skills emerged. Regarding the Conceptual domain, a greater deficit in Functional Academics was observed. In the Practical domain, we found a greater impairment in Self-Care skills. Conversely, Home Living skills appeared as a strength compared to other skills. The results are discussed in reference to literature.

The Validity of the Holtzman Inkblot Technique: New Indices.

Objective: The present study examines the validity of 11 new Holtzman Inkblot Technique indices. These were chosen from Exner's Comprehensive System (RCS) indices using two criteria: first, they had to be valid according to meta-analysis, and second, they must be computed using the HIT standard scoring system. Methods: Both techniques were administrated with a retest interval from 1 to 7days to a sample of 139 subjects (63 males and 76 females) from the general population. The validity of the new indices was studied through Pearson correlation (r) with the corresponding RCS indices. Results: Nine of the 11 new indices (R-HIT, F%-HIT, M-HIT, m-HIT, C'-HIT, Blends-HIT, PureH-HIT, DQ+HIT, and X-%-HIT) showed significant correlations with Rorschach scales, confirming our hypotheses. The correlation ranged from a minimum of 0.144 to a maximum of 0.414. Conclusions: The results provide support for the validity of the new HIT indices and have important implications for both clinical and research fields.

Intelligence and working memory: evidence from administering the WAIS-IV to Italian adults and elderly.

The present study took advantage of data collected on more than 2100 Italian adult and elderly individuals during the standardization of the WAIS-IV to examine the relationship between working memory (WM) components and intelligence, and how age affects this relationship. Administering the WAIS-IV enabled us to obtain five different measures for assessing different aspects of WM, and a measure of General Ability (GA) strongly loading on the g-factor. The main results were as follows: (1) age-related impairments in WM are substantial, and they are partly similar and partly different for the various WM measures; (2) the relationship between the WM measures and the General Ability Index (GAI) varies, becoming stronger when the active control required by the WM task is higher; (3) comparing the WM-GAI relationships between different age groups reveals some similar patterns, as well as some specific effects that depend on the WM task considered.

Intellectual functioning and executive functions in children and adolescents with attention deficit hyperactivity disorder (ADHD) and specific learning disorder (SLD).

Several studies have shown neuropsychological deficits across multiple domains in attention deficit hyperactivity disorder (ADHD) and specific learning disorder (SLD), but differences and similarities between these disorders have been little considered. We were interested in analyzing the intellectual and executive profiles in a sample of children and adolescents, divided according to the diagnosis into the ADHD group and the SLD group, and in identifying the differences and similarities between these disorders. The sample included two clinical groups: the first included 36 children and adolescents with a diagnosis of ADHD (5-15 years; mean = 9.42; SD = 2.22) while the second included 36 children and adolescents with a diagnosis of SLD (7-15 years; mean = 9.43; SD = 2.25). The WISC-IV was used to measure intellectual ability and the NEPSY-II was employed to measure executive functions. The results showed that the SLD group had significantly higher scores than the ADHD group on the NEPSY-II in the inhibition, cognitive flexibility, short-term verbal memory and verbal working memory domains. The ANCOVA showed differences regarding the FSIQ of WISC-IV, in that the SLD group obtaining higher scores than ADHD group. Findings showed that ADHD children are more impaired than SLD children, in particular in cognitive inhibition, cognitive flexibility, verbal memory, working memory and intellectual functioning. The recognition of the strengths and weaknesses of children and adolescents with ADHD and SLD allows to outline an educational and clinical intervention focused on their specific executive and intellectual functioning.

Cognitive Profile of Intellectually Gifted Adults: Analyzing the Wechsler Adult Intelligence Scale.

The Wechsler Adult Intelligence Scale (WAIS) has been used extensively to study intellectual abilities of special groups. Here, we report the results of an intellectually gifted group on the WAIS-IV. Gifted individuals are people who obtained scores equal to or greater than 2 standard deviations above the mean on an intelligence test. Hence, the current study aims first, to examine mean group performance data of gifted individuals on the WAIS-IV; second, to revalidate the pattern of performance identified in this special group in previous studies (i.e., verbal skills higher than all other abilities); third, to compare scatter measures across intellectual domains with a matched comparison group. A total of 130 gifted individuals (79 males) were administered the full battery and their performance was compared with a matched comparison group. Analyses revealed that gifted group displayed higher scores in all intellectual domains. Contrary to expectations, they showed the highest scores in perceptual reasoning tasks. A multivariate approach revealed that this ability was statistically different from all other domains within the gifted group. Moreover, gifted individuals showed higher discrepancies across intellectual domains than average-intelligence people. Findings have important practical implications to detect intellectual giftedness in adulthood.

Face memory and face recognition in children and adolescents with attention deficit hyperactivity disorder: A systematic review.

This review focuses on facial recognition abilities in children and adolescents with attention deficit hyperactivity disorder (ADHD). A systematic review, using PRISMA guidelines, was conducted to identify original articles published prior to May 2017 pertaining to memory, face recognition, affect recognition, facial expression recognition and recall of faces in children and adolescents with ADHD. The qualitative synthesis based on different studies shows a particular focus of the research on facial affect recognition without paying similar attention to the structural encoding of facial recognition. In this review, we further investigate facial recognition abilities in children and adolescents with ADHD, providing synthesis of the results observed in the literature, while detecting face recognition tasks used on face processing abilities in ADHD and identifying aspects not yet explored.

Intellectual efficiency in children and adolescents with spina bifida myelomeningocele and shunted hydrocephalus.

We studied the intellectual profiles of 13 Italian children diagnosed with spina bifida myelomeningocele and shunted hydrocephalus (MMC HC) against a control group of children. The results showed that MMC HC group had lower performance in all subtests, four indices, and the FSIQ of the Wechsler Intelligence Scale for Children, forth-edition. The MMC HC group showed flat cognitive profiles between subtests within each index and between four core indices. However, the cognitive abilities that were mostly impaired seemed to be related to visual selective and focused attention, to visual acuity, to visuo-perceptive organization and visuomotor integration and to visual short-term memory.

When divided attention fails to enhance memory encoding: The attentional boost effect is eliminated in young-old adults.

In the Attentional Boost Effect (ABE), images or words presented with to-be-responded target squares are later recognized more accurately than images or words presented with to-be-ignored distractor squares. Surprisingly, previous studies investigating the ABE have always examined young participants: thus, the question of whether this memory facilitation can be also observed in older adults has never been tested. The present study sought to fill this gap by examining whether healthy aging modulated the size of the ABE in 4 experiments in which the nature of the background stimuli (images vs. words), the length of the encoding trials (500 vs. 1,000 ms), and the type of instructions given to participants (incidental vs. intentional) were varied. In all cases, the results showed that the ABE was robust and significant in younger adults, whereas it was completely abolished in older adults. It is suggested that the detection of target squares required more attention resources in older than in younger adults, and that these resources were subtracted from the encoding of target-associated stimuli; thus, reducing or eliminating the ABE in the older group. Alternative explanations are also discussed. (PsycINFO Database Record

Normative Data for the Hayling and Brixton Tests in an Italian Population.

OBJECTIVE: The Hayling and Brixton tests constitute a short test battery that quickly assesses verbal and spatial inhibition and flexibility. This battery has shown high construct validity and strong reliability in clinical and experimental settings. The aim of this study was to develop an Italian version of the Hayling and Brixton tests and obtain normative values. METHOD: We collected normative data from 301 healthy Italian participants aged between 16 and 94 years, taking into account all demographics. To maximize the sample size, we used the overlapping interval strategy. Adjusted scores for demographics were obtained by linear regression analysis. RESULTS: The performance on the Hayling and Brixton tests was influenced by age and education. In particular, age affected verbal accuracy and response time on the Hayling Sentence Completion Test, whereas education only affected the former. Differently, the spatial component, as measured by the Brixton Spatial Anticipation Test, was shaped only by age, which decreased the number of correct responses. CONCLUSIONS: Our study provides normative data that have been adjusted for relevant demographics and percentile grids in an Italian population. Our data support the use of the Hayling and Brixton tests as a valid instrument for performing neuropsychological evaluations and longitudinal analyses of executive functions in clinical practice and for research purposes.

Psychological implications of abortion: a longitudinal study on two cohorts of women who recur to elective and therapeutic abortion.

OBJECTIVE: The aim of this work was to identify risk predictors of a negative psychological outcome among personal, situational and systemic characteristics of women who choose to interrupt a pregnancy by elective (e.g., not feeling ready for giving birth) or therapeutic means (e.g., fetal abnormalities). METHODS: A prospective study on two cohorts were conducted and focused on a group of women: the first recurred to elective abortion (VTP) (n=20) and the second recurred to therapeutic abortion (TTP) (n=30). The psychological distress was measured before and after abortion through the administration of two psychometric tests: SCL-90-r and CES-D. Dependent samples t-test was used to evaluate the tendency of the two cohorts' mean scores before and after abortion; repeated measures analysis of variance (ANOVA) was used to analyze the variance of mean scores of subgroups isolated for variables of interest before and after abortion. RESULTS: After the termination of pregnancy, in VTP a significant decrease between t-0 and t-1 mean score (p<0.05) was observed in all SCL-90-r's global scores and subscales: GSI (p=0.036), PST (p=.031), PSDI (p=0.004), SOM (p=0.009), DEP (p=0.032), ANX (p=0.036) and even in CES-D score of DEP (p=0.017) and SOM (p=0.011) subscales. In TTP a relevant decrease was found in SCL-90's SOM (p=0.023) and ANX, (p=0.016) subscales and in CES-D total score (p=0.020), POS (p=0.014) and SOM (p=0.09)subscales. In VTP group presence of partner support and absence of relational problems resulted as protective factors from a worse outcome. CONCLUSION: The results of this study suggest that, following an induced abortion, women experienced a significant improvement in the mood state compared to the period before the event; poor partner support and relational problems related with the abortion emerged as risk factors for a significantly worse psychological outcome compared to other causes interruption of pregnancy.

The Impact Of Dispositional Variables Of Elders, Relatives, And Paid Caregivers On Elders' Empowerment And Life Satisfaction.

Background/Study Context: The impact of dispositional characteristic of elders' closest network members on elders' life satisfaction and empowerment has remained largely unexplored. This innovative study aimed to assess the impact of dispositional variables of elders, relatives, and paid caregivers on life satisfaction and empowerment of elders. METHODS: One hundred forty-three triads (one elder, one paid caregiver, and one relative) completed six scales measuring modifiable personality characteristics (loneliness, optimism, regulation of positive and negative emotions), life satisfaction, and sense of empowerment. RESULTS: Two dispositional variables of relatives (positivity and ability to set goals) and one dispositional variable of care workers (self-satisfaction) were significantly related to life satisfaction of elders. Positivity of elders and the capacity to set objectives of the family members affected empowerment of elders. CONCLUSION: Future interventions aiming to improve life satisfaction and empowerment of elders should focus on these modifiable dispositional variables.

Dispositional characteristics, relational well-being and perceived life satisfaction and empowerment of elders.

OBJECTIVES: The broad purpose of this research is to identify the key modifiable variables most related to elders' life satisfaction and empowerment in order to improve the efficacy of interventions projects. Our study aims to integrate the theoretical perspectives of personality and community psychology focusing both on dispositional characteristics and relational well-being of elders, investigating triads, composed by an elder, a paid caregiver and the most involved relative. This study explores the impact of (1) some socio-demographic characteristics of elders, (2) some modifiable dispositional variables of elders and (3) elders' relational well-being on elders' empowerment and life satisfaction. METHOD: The study involved 429 people in 143 triads. Semi-structured interviews with elders, paid caregiver and close relatives were used to construct a new pilot measure of elders' relational well-being. Life Satisfaction, Empowerment, Loneliness, Positivity, Humor and Emotions self-efficacy scales were also administered. Hierarchical multiple regressions were performed. RESULTS: Elders' positivity, relational well-being of elders and living alone were significantly related to empowerment. Elders' relational well-being and positivity significantly contributed to life satisfaction. DISCUSSION: Interventions to increase empowerment and life satisfaction should focus primarily on augmenting positivity and relational well-being integrating the theoretical premises of both personality and community psychology.

Sexting, psychological distress and dating violence among adolescents and young adults.

BACKGROUND: Sexting is the exchange of sexually explicit or provocative content (text messages, photos, and videos) via smartphone, Internet, or social networks. Recent evidence enlightened its relationships with several risk and aggressive behaviors. This study aimed to investigate the relationship between the amount of sexting, psychological distress, and dating violence in adolescents and young adults. METHOD: The study involved 1,334 participants (68% females; mean age = 20.8) who completed a survey containing Kinsey Scale, Sexting Behavior Questionnaire, Conflict in Adolescent Dating Relationships Inventory, and General Health Questionnaire. RESULTS: Results showed gender and sexual orientation differences: Males (vs. females) did more sexting, while non-heterosexuals (vs. heterosexuals) were more involved in sexting. Moreover, high/moderate users of sexting committed more offline and online dating violence. Regarding psychological distress, no differences were found between high and low/moderate users of sexting. CONCLUSIONS: Results suggested that moderate and high use of sexting could be a risk factor for some problematic behaviors such as dating violence, even if there is not a relationship with anxiety and depression symptoms.

Forward and backward digit span difficulties in children with specific learning disorder.

This study examined performance in the forward and backward digit span task of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) in a large group of children with specific learning disorder (SLD) as compared with a group of typically developing children matched for age and sex. Our results further support the hypothesis that the intellectual difficulties of children with SLD involve working memory in the forward digit span task to a greater extent than in the backward digit span task. The correlation of the two spans with a General Ability Index (GAI) was similar in SLD, and smaller in magnitude than in typically developing children. Despite a GAI within normal range, children with SLD had difficulty with both digit span tasks, but more so for forward span. This pattern was similar for different SLD profiles with clinical diagnoses of dyslexia and mixed disorder, but the impairments were more severe in the latter. Age differences were also investigated, demonstrating larger span impairment in older children with SLD than in younger.

Differences in the intellectual profile of children with intellectual vs. learning disability.

The WISC-IV was used to compare the intellectual profile of two groups of children, one with specific learning disorders (SLDs), the other with intellectual disabilities (ID), with a view to identifying which of the four main factor indexes and two additional indexes can distinguish between the groups. We collected information on WISC-IV scores for 267 children (Mage=10.61 [SD=2.51], range 6-16 years, females=99) with a diagnosis of either SLD or ID. Children with SLD performed better than those with ID in all measures. Only the SLD children, not the ID children, revealed significant differences in the four main factor indexes, and their scores for the additional General Ability Index (GAI) were higher than for the Cognitive Proficiency Index (CPI). Children with a diagnosis of SLD whose Full-Scale Intelligence Quotient (FSIQ) was <85 showed a similar pattern. Our findings confirm the hypothesis that children with SLD generally obtain high GAI scores, but have specific deficiencies relating to working memory and processing speed, whereas children with ID have a general intellectual impairment. These findings have important diagnostic and clinical implications and should be considered when making diagnostic decisions in borderline cognitive cases.

Validity of a figure rating scale assessing body size perception in school-age children.

This study aimed to provide data concerning the validity of a short sequence of face valid pictorial stimuli assessing the perception of body size in school-age children. A sequence of gender and age-appropriate silhouettes was administered to 314 boys and girls aged 6-14 years. The self-evaluations provided by the children correlated significantly with their actual BMI corrected for age. Furthermore, the children's self-evaluations always significantly correlated with the evaluations provided by the three external observers; i.e., both parents and the interviewers. The results indicate that this sequence of pictorial stimuli, depicting realistic human forms appropriate for children, is a valid measure of children's body image. Relevant differences across age groups were also found, indicating that before the age of eight, the correlations between the children's self-evaluations and their BMI or the judgments of the three observers are lower than in the other age groups.

The Value of Removing Daily Obstacles via Everyday Problem-Solving Theory: Developing an Applied Novel Procedure to Increase Self-Efficacy for Exercise.

The objective of the study was to develop a novel procedure to increase self-efficacy for exercise. Gains in one's ability to resolve day-to-day obstacles for entering an exercise routine were expected to cause an increase in self-efficacy for exercise. Fifty-five sedentary participants (did not exercise regularly for at least 4 months prior to the study) who expressed an intention to exercise in the near future were selected for the study. Participants were randomly assigned to one of three conditions: (1) an Experimental Group in which they received a problem-solving training session to learn new strategies for solving day-to-day obstacles that interfere with exercise, (2) a Control Group with Problem-Solving Training which received a problem-solving training session focused on a typical day-to-day problem unrelated to exercise, or (3) a Control Group which did not receive any problem-solving training. Assessment of obstacles to exercise and perceived self-efficacy for exercise were conducted at baseline; perceived self-efficacy for exercise was reassessed post-intervention (1 week later). No differences in perceived challenges posed by obstacles to exercise or self-efficacy for exercise were observed across groups at baseline. The Experimental Group reported greater improvement in self-efficacy for exercise compared to the Control Group with Training and the Control Group. Results of this study suggest that a novel procedure that focuses on removing obstacles to intended planned fitness activities is effective in increasing self-efficacy to engage in exercise among sedentary adults. Implications of these findings for use in applied settings and treatment studies are discussed.

Construction and validation of an ecological version of the Wisconsin Card Sorting Test applied to an elderly population.

The goal of this project was to construct and validate an ecological version of the Wisconsin Card Sorting Test (WCST) aimed at the elderly. This was accomplished by replacing the geometric stimuli of the traditional version with stimuli belonging to the semantic category of transport vehicles, and by elimination of the color yellow. The results showed the ecological WCST version was preferred over the traditional version and older people felt less tired during test performance. In the two independent normal elderly groups, all pairs of scores that can be derived from the WCST correlated significantly with each other. Six of 11 outcome measures of the traditional WCST-128 (long) version were significantly influenced by age. By contrast, in the WCST-64 (short) version and in the ecological WCST-54 version only one measure was affected by the age variable. No significant effect of education level or gender emerged from the results in any WCST version. Again, the subjects with cognitive deterioration had lower performance in the ecological WCST-54 version than in the two traditional WCST versions. It seems reasonable to assume that the ecological version of WCST is more discriminating and has more advantages than the traditional versions. Further research on individual differences in the performance on this task will increase understanding of the components of the test, and of the variety of factors and possible deficits that could lead to an impaired performance of the test.
