RESUMO

Phylogenetic, developmental, and brain-imaging studies suggest that human personality is the integrated expression of three major systems of learning and memory that regulate (1) associative conditioning, (2) intentionality, and (3) self-awareness. We have uncovered largely disjoint sets of genes regulating these dissociable learning processes in different clusters of people with (1) unregulated temperament profiles (i.e., associatively conditioned habits and emotional reactivity), (2) organized character profiles (i.e., intentional self-control of emotional conflicts and goals), and (3) creative character profiles (i.e., self-aware appraisal of values and theories), respectively. However, little is known about how these temperament and character components of personality are jointly organized and develop in an integrated manner. In three large independent genome-wide association studies from Finland, Germany, and Korea, we used a data-driven machine learning method to uncover joint phenotypic networks of temperament and character and also the genetic networks with which they are associated. We found three clusters of similar numbers of people with distinct combinations of temperament and character profiles. Their associated genetic and environmental networks were largely disjoint, and differentially related to distinct forms of learning and memory. Of the 972 genes that mapped to the three phenotypic networks, 72% were unique to a single network. The findings in the Finnish discovery sample were blindly and independently replicated in samples of Germans and Koreans. We conclude that temperament and character are integrated within three disjoint networks that regulate healthy longevity and dissociable systems of learning and memory by nearly disjoint sets of genetic and environmental influences.

RESUMO

BACKGROUND: Low self-esteem (LSE) has been associated with several psychiatric disorders, and is presumably influenced by transdiagnostic factors. Our study was based both on investigations of the relationship between depression and LSE (vulnerability, scar, reciprocal models) and on theories of cognitive factors contributing to the development and maintenance of LSE, such as Melanie Fennell's model, the catalyst model and the Self-Regulatory Executive Function model. AIMS: Based on the theories above, in our cross-sectional study we aimed at understanding more specifically the transdiagnostic factors that can maintain LSE in a heterogeneous clinical sample. METHOD: Six hundred and eleven out-patients were assessed by SCID-I and self-report questionnaires. The model was tested by structural equation modelling. RESULTS: Based on the fit indices, the hypothesis model did not fit the data; therefore, a modified transdiagnostic model was emerged. This model made a good fit to the data [χ2 (12, n=611)=76.471, p<.001; RMSEA=.080, CFI=.950, TLI=.913] with a strong explanatory power (adj R2=.636). Severe stressful life events and depressive symptoms lead to LSE indirectly. Self-blame, perfectionism, seeking love and hopelessness have been identified as mediating factors in the relationship between depressive symptoms and LSE. Although there was a significant correlation between state-anxiety and LSE, as well as LSE and rumination, these two factors did not fit into the model. CONCLUSIONS: The new transdiagnostic model of LSE has great potential in the treatment of various mental conditions and may serve as a guide to developing more focused and more effective therapeutic interventions.

RESUMO

Experimental studies of learning suggest that human temperament may depend on the molecular mechanisms for associative conditioning, which are highly conserved in animals. The main genetic pathways for associative conditioning are known in experimental animals, but have not been identified in prior genome-wide association studies (GWAS) of human temperament. We used a data-driven machine learning method for GWAS to uncover the complex genotypic-phenotypic networks and environmental interactions related to human temperament. In a discovery sample of 2149 healthy Finns, we identified sets of single-nucleotide polymorphisms (SNPs) that cluster within particular individuals (i.e., SNP sets) regardless of phenotype. Second, we identified 3 clusters of people with distinct temperament profiles measured by the Temperament and Character Inventory regardless of genotype. Third, we found 51 SNP sets that identified 736 gene loci and were significantly associated with temperament. The identified genes were enriched in pathways activated by associative conditioning in animals, including the ERK, PI3K, and PKC pathways. 74% of the identified genes were unique to a specific temperament profile. Environmental influences measured in childhood and adulthood had small but significant effects. We confirmed the replicability of the 51 Finnish SNP sets in healthy Korean (90%) and German samples (89%), as well as their associations with temperament. The identified SNPs explained nearly all the heritability expected in each sample (37-53%) despite variable cultures and environments. We conclude that human temperament is strongly influenced by more than 700 genes that modulate associative conditioning by molecular processes for synaptic plasticity and long-term memory.

RESUMO

Human personality is 30-60% heritable according to twin and adoption studies. Hundreds of genetic variants are expected to influence its complex development, but few have been identified. We used a machine learning method for genome-wide association studies (GWAS) to uncover complex genotypic-phenotypic networks and environmental interactions. The Temperament and Character Inventory (TCI) measured the self-regulatory components of personality critical for health (i.e., the character traits of self-directedness, cooperativeness, and self-transcendence). In a discovery sample of 2149 healthy Finns, we identified sets of single-nucleotide polymorphisms (SNPs) that cluster within particular individuals (i.e., SNP sets) regardless of phenotype. Second, we identified five clusters of people with distinct profiles of character traits regardless of genotype. Third, we found 42 SNP sets that identified 727 gene loci and were significantly associated with one or more of the character profiles. Each character profile was related to different SNP sets with distinct molecular processes and neuronal functions. Environmental influences measured in childhood and adulthood had small but significant effects. We confirmed the replicability of 95% of the 42 SNP sets in healthy Korean and German samples, as well as their associations with character. The identified SNPs explained nearly all the heritability expected for character in each sample (50 to 58%). We conclude that self-regulatory personality traits are strongly influenced by organized interactions among more than 700 genes despite variable cultures and environments. These gene sets modulate specific molecular processes in brain for intentional goal-setting, self-reflection, empathy, and episodic learning and memory.

RESUMO

INTRODUCTION: The long-lasting threat of COVID-19 makes it necessary to explore strategies to improve coping skills which enable us to master a balanced life in the face of adversity. OBJECTIVE: To unravel the most challenging aspects of COVID-19 in a nonclinical adult population and identify predictors of lost balance and consequent allostatic overload (AO). We examined the role of regular, moderate-intensity formula aerobic exercise (312 meridian exercise) in preventing allostatic overload through increasing well-being. METHODS: An online survey was conducted to measure CO-VID-related allostatic overload according to clinimetric criteria. The Psychosocial Index (PSI), Kellner's Symptom Questionnaire (KSQ), short Depression Anxiety Stress Scales (DASS-21), Public Health Surveillance Well-Being Scale -(PHS-WB), and Whiteley-7 were used to explore mental health characteristics. Univariate statistics logistic regression analysis and a general linear model were used. RESULTS: According to 442 valid answers, 217 adults practiced physical exercise (PE) frequently (fPE, 3-5 times/every day) while 120 did it less regularly (1-2 times/week), and 105 did not exercise/practiced irregularly (controls). Restriction-related stressors were most challenging, resulting in AO in 29% (n = 128) of the sample. The main predictors were additional stressors (p = 0.005) and anxiety symptoms (p < 0.001). The prevalence of AO was lower (p = 0.018) in the fPE group when compared to controls. KSQ distress symptoms were also lower in fPE (p < 0.0001), while total well-being was increased (p < 0.001) after adjusting for sex, age, and number of chronic diseases. According to the PHS-WB, both physical and mental well-being were higher (p = 0.003 and p = 0.004, respectively) in fPE. CONCLUSIONS: Frequent moderate exercise is associated with better mental and physical well-being and a lower prevalence of AO.

RESUMO

Background and Objectives: The role of affective temperament in the genesis and outcome of major mood disorders is well studied, but there are only a few reports on the relationship between panic disorder (PD) and affective temperaments. Accordingly, we aimed to study the distribution of affective temperaments (depressive (DE); cyclothymic (CT); irritable (IRR); hyperthymic (HT) and anxious (ANX)) among outpatients with PD. Materials and Methods: Affective temperaments of 118 PD outpatients (80 females and 38 males) with or without agoraphobia but without any other psychiatric disorder at the time of inclusion were evaluated using the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) and compared with the affective temperament scores of control subjects. All patients were followed up for at least 1.5 years in order to detect the onset of any major affective disorders, substance use disorders and suicide attempts. Results: Among females, the dominant ANX and DE temperaments were four and three times as common as in a large normative Hungarian sample (for both cases p < 0.01). Among male PD patients, only the dominant DE temperament was slightly overrepresented in a non-significant manner. Females with PD obtained significantly higher scores on ANX, DE and CT subscales of the TEMPS-A, whereas males with PD showed significantly higher scores on ANX, DE and HT temperament subscales compared with the members of a large normative Hungarian sample and also with a gender- and age-matched control group. During the follow-up, newly developed unipolar major depression and bipolar spectrum (bipolar I or II and cyclothymic) disorders appeared in 64% and 22% of subjects, respectively. Conclusions: Our preliminary findings suggest that a specific, ANX-DE-CT affective temperament profile is characteristic primarily for female patients, and an ANX-DE-HT affective temperament profile is characteristic for male patients with PD, respectively. These findings are in line with expectations because PD is an anxiety disorder par excellence on the one hand, whereas, on the other hand, it is quite frequently comorbid with mood (including bipolar) disorders.

RESUMO

BACKGROUND: The Opening Minds Stigma Scale for Health Care Providers (OMS-HC) is a widely used questionnaire to measure the stigmatising attitudes of healthcare providers towards patients with mental health problems. The psychometric properties of the scale; however, have never been investigated in Hungary. We aimed to thoroughly explore the factor structure of the OMS-HC and examine the key psychometric properties of the Hungarian version. METHODS: The OMS-HC is a self-report questionnaire that measures the overall stigmatising attitude by a total score, and three subscales can be calculated: Attitude, Disclosure and Help-seeking, and Social Distance. Our study population included specialists and trainees in adult and child psychiatry (n = 211). Exploratory and confirmatory factor analyses were performed, and higher-order factors were tested. We calculated the test-retest reliability on a subgroup of our sample (n = 31) with a follow-up period of 1 month. The concurrent validity of the scale was measured with the Mental Illness: Clinician's Attitudes-4 scale (MICA-4). RESULTS: Three factors were extracted based on a parallel-analysis. A bifactor solution (a general factor and three specific factors) showed an excellent model-fit (root mean square error of approximation = 0.025, comparative fit index = 0.961, and Tucker-Lewis index = 0.944). The model-based reliability was low; however, the general factor showed acceptable reliability (coefficient omega hierarchical = 0.56). The scale demonstrated a good concurrent validity with the MICA-4 [intraclass correlation coefficient (ICC) = 0.77]. The test-retest reliability was excellent for the general factor (ICC = 0.95) and good for the specific factors (ICC = 0.90, 0.88, and 0.84, respectively). CONCLUSIONS: The three dimensions of the OMS-HC was confirmed, and the scale was found to be an adequate measure of the stigmatising attitude in Hungary. The bifactor model is more favourable as compared to the three correlated factor model; however, despite the excellent internal structure, its model-based reliability was low.

RESUMO

BACKGROUND AND AIMS: The importance of personality characteristics in the diagnosis and treatment of gambling disorder (GD) and alcohol use disorder (AUD) is often highlighted in scientific literature. This study aimed to test predictions about the associations of temperament and character in chronic AUD patients with comorbid GD symptoms and without them. METHODS: Chronic AUD patients enrolled from an inpatient clinic were divided in two groups based on cluster analysis, AUD patients with (AUD + GD group: n = 30) and without (AUD group: n = 68) GD symptoms. Severity of GD symptoms and personality dimensions (Cloninger's Temperament and Character Inventory Revised, TCI-R) were assessed. Associations of tested variables were analysed with analysis of covariance, one-sample and independent sample t-tests. RESULTS: GD symptoms proved to be a clustering factor in terms of personality, where AUD + GD group expressed a more maladaptive personality profile. Compared to Hungarian normative TCI-R scores, both patient groups showed elevated levels of Harm Avoidance and Novelty Seeking with lower scores of Self-directedness, while the AUD + GD group scored lower on Persistence and Cooperation as well. The AUD + GD group reported significantly higher levels of Harm Avoidance, with lower scores of Reward Dependence compared to the AUD group. DISCUSSION: Comorbid GD symptom severity is an important factor in chronic AUD, where AUD patients with comorbid GD symptoms exhibited a more maladaptive personality constellation than singular AUD patients. These emphasize the need of special attention for comorbid GD symptoms in AUD, since treatment recommendations and prognosis for them may also differ.

RESUMO

BACKGROUND AND PURPOSE: In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. METHODS: Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. RESULTS: People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. CONCLUSION: Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person's impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary.

RESUMO

Various mixture modeling approaches have been proposed to identify within-subjects differences in the psychological processes underlying responses to psychometric tests. Although valuable, the existing mixture models are associated with at least one of the following three challenges: (1) A parametric distribution is assumed for the response times that-if violated-may bias the results; (2) the response processes are assumed to result in equal variances (homoscedasticity) in the response times, whereas some processes may produce more variability than others (heteroscedasticity); and (3) the different response processes are modeled as independent latent variables, whereas they may be related. Although each of these challenges has been addressed separately, in practice they may occur simultaneously. Therefore, we propose a heteroscedastic hidden Markov mixture model for responses and categorized response times that addresses all the challenges above in a single model. In a simulation study, we demonstrated that the model is associated with acceptable parameter recovery and acceptable resolution to distinguish between various special cases. In addition, the model was applied to the responses and response times of the WAIS-IV block design subtest, to demonstrate its use in practice.

RESUMO

INTRODUCTION: Empirical research in defense mechanisms - a concept that stem from the work of Sigmund and Anna Freud and gave rise to a number of thematic approaches - dates back to the mid-20th century. From the psychometric measure instruments developed since that time, the present investigation was aimed to assess the short form of Defense Style Questionnaire that can be efficiently applied in clinical practice and that was supposed to be used as the sixth diagnostic factor of the new version of DSM. A multi-level validity analysis of DSQ-40 was carried out. METHODS: We applied trait assessing measures for anxiety, avoidant behavior, schizotypal traits and personality disorder diagnostic measures developed for DSM-5. To evaluate discriminant validity we applied instruments that assess the stability of self-esteem and the state of self and that can measure the clarity of self-representations. 670 healthy university students volunteered to participate in the investigation. RESULTS: Based on the applied questionnaires, it was revealed that its inner consistency and validity measures are adequate. Its factors that discriminate neurotic and immature defense styles can be applied to identify persons inclined to use either adaptive or maladaptive defense mechanisms. Our findings correspond to other international research results. CONCLUSION: Our results attest that DSQ-40 is a reliable instrument to assess defense style.

RESUMO

BACKGROUND AND PURPOSE: The relationship of schizophrenia and its milder, subclinical forms, with creativity has been in the centre of theoretical interest for decades, however, the systematic research of the topic only prevailed more recently. Purpose - Here we aimed to examine the connection between different schizotypal and non-schizotypal personality traits and verbal creativity in a nonclinical sample. We also investigated the correspondence of two schizotypy inventories, the Oxford-Liverpool Inventory of Feelings and Experiences and a special character configuration of the Temperament and Character Inventory associated with schizotypy. METHODS: 57 healthy adults (14/43 m/f, mean age 21.51±1.43 years) - took part in the experiment. All participants received a detailed information sheet and gave informed consent prior to participation. Participants completed the Oxford-Liverpool Inventory and the Temperament and Character Inventory to measure both schizotypal and non-schizotypal personality traits. Torrance Test of Creative Thinking was used to measure verbal creativity. Associations between reported measures were examined with correlational and regression analyses. RESULTS: Out of the specific Temperament and Character configuration associated with schizotypy (low self-directedness, cooperativeness and high self- transcendence), we only found low self-directedness to be correlated significantly with Oxford-Liverpool schizotypy rates (Self-directedness-schizotypy: r=-.730, p<.01). There was no significant connection between schizotypal traits and verbal creativity. In our sample, the Self-directedness and Reward-dependence character and temperament subscales predicted significantly the verbal creativity level (Self-directedness: b=.330, p=.015; Reward - dependence: b=-.260; p=.049). CONCLUSION: Based on our results, besides schizotypal traits, other personality measures might be considered in relation to verbal creativity, providing further details to the empirical investigation of creativity. We found low self-directedness to be correlated with Oxford-Liverpool schizotypy rates, however, the sample size was not large enough to test the concurrent validity of the two inventories. Future studies might consider to extend the study sample, preferably to both clinical and non-clinical populations.

RESUMO

INTRODUCTION: The purpose of the Schizotypy Personality Questionnaire - Brief Revised (SPQ-BR) is to help the diagnosis of schizotypial personality disorders within the framework of the DSM-5 and identification of people with an increased vulnerability towards schizophrenia related symptoms. The aim of our current study is twofold; validation of the SPQ-BR's Hungarian adaptation and investigating it's latent structure. METHODS: The sample consisted of 1702 Hungarian university students and university graduated persons. Exploratory factor analytic procedures were performed, cross-validating their results by the use if confirmatory factor analysis. RESULTS: The results suggested that the Hungarian SPQ-BR is best represented by a model of the hierarchical structure, reflected by seven first order factors, and two higher order dimensions of positive and negative symptoms. On lower order factors males were shown significantly greater constricted affects, and proneness to eccentric behaviors and unusual perceptions, while females were characterized by higher magical thinking, next to stronger social anxieties. Gender differences in the Ideas of references - Suspicion and odd speech scales were found to be non-significant. Concerning it''s validity with other scales we found that magical thinking and unusual perceptions from the positive symptoms significantly positively correlated with the magical ideation (MI), anxiousness (ASI), and self-concept clarity (SCCS) scales, next to a negative correlation between unusual perceptions and the self-esteem (RSES) scale. Among the negative symptoms the No close friends-Constricted affect and the Ideas of references - Suspicion subscales showed significant negative linear associations with the ASI, SCCS scales. CONCLUSION: The Hungarian version of the SPQ-BR showed adequate psychometrical properties, it was found to be reliable.

RESUMO

INTRODUCTION: This study aimed at assessing the reliability and construct validity of the TCI-140. SAMPLE: 428 Italian participants. EXCLUSION CRITERIA: psychiatric disorders. 100 subjects - longitudinal retest study. RESULTS: The results of descriptive statistics of internal consistency reliabilities (Cronbach coefficient) of TCI-R dimensions showed: a strong internal consistence of the scales: HA (α = 0.84); RD (α = 0.70); SD (α = 0.86); C (α = 0.75); ST (α = 0.83); a low level in NS (α = 0.60). In relation to facets, internal consistency reliabilities (Cronbach coefficient) ranged from 0.14 C3 to 0.79 C4 (from 3rd to 4th facet of C scale). Correlations: highest inverse correlation between HA and SD (r = -0.56); moderate inverse correlations for: HA and PS (r = -0.37); C and RD(r = 0.32); C and SD (r = 0.44). P, SD, C and ST showed good inter class correlations (ICC) ≥ 70 maintaining a good stability of the measures over the time. Four factors accounted for 56.3% of the variance for temperament subscale. Subscales of: PS4, PS3 PS2, PS1, NS3 for factor 1; HA2, HA1, HA4, HA3 for factor 2; RD1, RD2 and RD3 for factor 3; NS4, NS1 and NS2 for factor 4. Three factors that were identified accounted for 58.3% of the variance for character subscales of: SD3, SD5, SD1, SD2 for factor 1; C4, C1, C5, SD4, C3 for factor 2; ST2, ST1, ST3, C2 for factor 3. CONCLUSION: The reliability coefficients were significantly good for some dimensions of TCI-140 and showed a good correlation after time, while some dimensions as NS have low reliability. In the principal components analysis does not saturate all dimensions in its theoretical factor. Moreover TCI-140 is a useful inventory for the evaluation of the principal dimensions of temperament and character.

RESUMO

OBJECTIVE: The goal of this study was to investigate psychometric properties and factorial structure of the Croatian adaptation of the Temperament and Character Inventory-Revised (TCI-R) in a sample of psychiatric outpatients (n=328). METHOD: The participants filled out the TCI-R, as well as self-report measures of the Big-Five personality traits (IPIP-50), trait impulsivity (BIS-11), depression (BDI-II), suicidality (SBQ-R), and life satisfaction (SWLS). We explored the internal consistency of 7 domains and 29 subscales and compared it with the Croatian version of the original TCI used in prior studies. Principal component analysis with promax rotation was conducted on temperament and character subscales separately, while concurrent validity was examined through the TCI-R's relations with the abovementioned psychological measures. RESULTS: The TCI-R scales showed adequate internal consistencies, with Cronbach's alpha values ranging from 0.77 to 0.93. The internal consistency showed to be higher in comparison with the Croatian version of the original TCI. The postulated four-factor structure of temperament and the three-factor structure of character were confirmed. The meaningful associations with other measures supported the concurrent validity of the TCI-R. CONCLUSION: The Croatian adaptation of the TCI-R exhibited satisfactory reliability and validity in a sample of psychiatric outpatients. These findings support the use of the TCI-R in Croatian clinical settings over its predecessor (TCI).

RESUMO

BACKGROUND: Robert Cloninger's psychobiological model of temperament and character is a dimensional approach to personality assessment and gave birth to the temperament and character inventory (TCI). The aim of the present report is to examine the psychometric properties of the Greek version of the TCI, and to replicate its postulated structure and provide preliminary normative data for the Greek population. METHODS: The study sample included 734 subjects from the general Greek population (436 females; 59.4 % and 298 males; 40.6 %). Their mean age was 40.80 ± 11.48 years (range 25-67 years). The mean age for females was 39.43 ± 10.87 years (range 25-65 years), while the mean age for males was 42.82 ± 12.06 years (range 25-67 years). Descriptive statistics tables concerning age, gender and occupational status distribution in the sample were created. The analysis included the calculation of Cronbach's alpha, factor analysis with promax rotation and the calculation of Pearson correlation coefficients between the subscales scores. Analysis of Covariance with age as covariate and t test and Cohen's d as post hoc tests was used to search for differences in subscales scores between males and females. RESULTS: The overall psychometric properties of the Greek version of the TCI proved to be satisfactory, with acceptable consistencies of the subscales. The factor analysis of temperament identified four factors which together explained 58.56 % of total variance, while the factor analysis of the three-factor solution of the character explained 52.24 % of total variance. The TCI scales correlate significantly but weakly between each other and with age. DISCUSSION: The Greek version of the TCI exhibits psychometric properties similar to its original English counterpart and to other national translations and it is suitable for use in research and clinical practice.

RESUMO

Temperament and character factors are strongly related to the developmental, clinical, and treatment aspects of alcohol dependence. This study had the aim of revealing the underlying personality structure and individual differences in the symptoms of alcohol dependence measured by multiple severity indicators. Patients with alcohol dependence exhibited higher levels of novelty seeking and harm avoidance, and lower levels of persistence, self-directedness, and cooperativeness. Especially novelty seeking was connected with more severe alcohol dependence. These characteristics could be useful targets of interventions and Temperament and Character Inventory is therefore a useful measurement to identify patients with more severe alcohol-related problems.

RESUMO

The role of adolescent personality concerning mental health, well-being, self development, and academic performance is an interesting aspect that needs more attention. The use of the JTCI (Junior Temperament and Character Inventory) can contribute to more knowledge and a better understanding of a possible influence of personality in this context. The aim of this study was to assess the psychometric properties of the Norwegian version of the JTCI among an adolescent sample in terms of factor analysis, reliability and validity. The sample included 2075 subjects in the age from 15-18years. We analyzed the factor structure, internal consistency, and validity of the measure. The Norwegian version of the JTCI was found to have good psychometric properties in terms of internal consistency, a reasonable factor structure and significant correlations with depression, self-esteem, and self-efficacy. However, further research on its differentiation of Harm Avoidance and Self-directedness is needed. The JTCI appears as a useful tool in addressing issues ranging from scholastic performance to developmental issues, mental health and well-being.

RESUMO

In our study we assessed the frequency of reported hopelessness and suicide attempts in the national representative survey Hungarostudy 2002. The randomly selected sample consisted of 14,000 individuals over the age of 18. We created a short version of the widely used Beck Hopelessness Scale for screening purposes in suicide prevention. The short version of the BHS consists of four items and has high internal consistency (Cronbach's alpha = 0.85). Moreover, we conducted an investigation into psychological, somatic, sociological and socio-economic as well as cultural variables that show a positive or negative correlation with hopelessness and important predictors of suicide. The following psychological variables showing a positive correlation with hopelessness were identified: dysfunctional attitudes, exhaustion, psychological distress, hostility, lack of life goals and inability to cope emotionally. Sense of coherence, social support, perceived self-efficiency, subjective well-being and problem-solving coping showed a negative correlation with hopelessness. Concerning the relationship between hopelessness and suicide attempts, we found that participants who attempted suicide in the last year scored higher (mean = 4.86) than participants who attempted suicide more than 3 years ago (mean = 3.57). These results indicate that applying the short version of the BHS could be very useful in general practice and in psychiatric care.

RESUMO

This research paper presents a case study analysis of the behavior of three Sedum varieties and their growth in three different types of substrates without additional watering or fertilizing. The study aims to identify a suitable substrate for propagation and to provide insight into the plant's growth patterns. By analyzing the growth of the Sedum species and varieties-SS'PW', SS'CB', and SS'P'-without intervening in their growth process, we were able to identify factors that play a more crucial role in promoting root growth, plant growth, aesthetic value, and use. Over a 20-month period, various technical tools were employed to conduct observations and measurements for both plants and weather conditions. The type of substrate significantly affected plant growth, with the green roof substrate exhibiting the highest overall average monthly root growth rate (0.92 ± 0.05 d, 1.01 ± 0.05 b, 0.96 ± 0.05 c) while in the case of stem growth, among all three varieties, the best results were obtained in the commercial mix (0.87 ± 0.04 a, 0.40 ± 0.02 c, 0.35 ± 0.02 d). Based on the morphological analyses, all values were significantly lower than the control. Best results for leaf weight and surface area were noticed in the green roof substrate with an average growth of 46%, 53%, 55%, and for stem weight, length, and thickness in the commercial mix with 64%, 61%, and 55% compared to the control, respectively. Leaves had varying morphological characteristics, but the chromatic characteristics were preserved. The plants had an overall poor growth which may not be desirable in landscape designs. The findings of this study are applicable in the planning and execution of eco-friendly infrastructure initiatives, leading to the development of more robust and environmentally friendly urban settings.
