Dominance-submissiveness cues modulate pain threshold for mechanical pressure.

Acute pain sensation is an inherently negative but adaptive experience; however, research on pain sensitivity shows that simple contextual cues can effectively attenuate the pain. In this study, we sought to investigate how dominance cues, manipulated as vertical spatial (i.e., height) distance between participants and experimenter, affect participants' pain sensitivity. Positioning participants in a spatially higher position relative to the experimenter was aimed to induce a feeling of dominance in participants. Conversely, a feeling of submissiveness was induced by placing the experimenter in a spatially higher position. In addition, we examined the role of dominance cues with respect to participants' and experimenters' gender. Two separate studies were conducted-Study 1 with a male experimenter measuring pain threshold in female and male participants (N = 137), and Study 2 with a female experimenter conducting pain measurement in a new sample of female and male participants (N = 122). The results of both studies demonstrated that participants in a dominant position reported a higher pain threshold relative to participants in a submissive position. Male participants had a higher pain threshold in both studies; however, Study 1 revealed a significant interaction of dominance manipulation and participant's gender, with the effect of dominance cues being larger in men.

Spirituality, Personality, and Emotional Distress During COVID-19 Pandemic in Croatia.

This study examined the association between spiritual quality of life (QoL), spiritual coping, emotional distress, and personality during the COVID-19 pandemic lockdown in a convenience sample of Croatian adults (n = 2,860, 80.6% women). Participants completed an online questionnaire that collected information on sociodemographic characteristics, distress (the Depression, Anxiety, and Stress Scale 21), spiritual coping and spiritual QoL (the WHO Quality of Life-Spirituality, Religiousness, and Personal Beliefs), and personality (the International Personality Item Pool). The hierarchical regression analysis demonstrated that personality traits, especially emotional stability, were the most significant predictors of mental health outcomes. Spiritual coping styles were a predictor of worse, while spiritual QoL of better psychological outcomes. Results demonstrate the complex relations between different aspects of spirituality/religiosity with personality and emotional outcomes and suggest that distress motivates the engagement of spiritual coping in times of disaster.

Predictors of emotional distress during the COVID-19 pandemic; a Croatian study.

The study aimed to assess relations between coronavirus-related psychological distress and its potentially predictive factors. An online sample of 2860 Croatian adults filled in questionnaires on socio-demographic characteristics, distress (the Depression, Anxiety and Stress Scale 21), coping (the Brief COPE), personality (the International Personality Item Pool), and social support (the Duke-UNC Functional Social Support Questionnaire) during the COVID-19 lockdown and after the capital was hit by an earthquake. Results indicated that 15.9% of the respondents experienced severe to extreme depression, 10.7% severe to extreme anxiety, and 26.2% severe to extreme stress. The hierarchical regressions analysis indicated that the considered variables explained a substantial percentage of the variance in depression (51.4%), anxiety (35.2%), and stress (45.5%). Main predictors of emotional distress were lower scores of Emotional Stability, higher scores of Agreeableness, avoidant coping, lack of active coping and perceived social support. The negative effect of the earthquake was weak. Results provide information on a broad range of potentially protective or vulnerability factors that could help identify those at risk for developing coronavirus-related psychological distress. Findings suggest that promoting active coping styles and social interactions could be preventive and potentially therapeutic in general populations.

Temperament and character in homicidal patients with schizophrenia.

Background: Understanding the etiology of violence in patients with schizophrenia is an issue of great clinical and public importance. Although personality traits are an important aspect in determining complex behaviors of schizophrenia patients, there is a lack of research on the relationship between personality traits and violence, especially homicidal behavior, in this population. Aim: We aimed to compare temperament and character dimensions between homicidal and other mostly violent forensic patients with schizophrenia, and to determine which temperament and character dimensions are associated with homicidal behavior in these patients. Methods: We recruited 71 male forensic schizophrenia patients without concomitant substance dependence and antisocial personality disorder. The patients were divided into two groups according to trial documentation as: (1) Homicide and attempted homicide group (N 30; 42%), and (2) Other offenses group (N 41; 58%). Patients were assessed by means of the Temperament and Character Inventory and the Positive and Negative Syndrome Scale. Differences between groups were tested with t-test. Results: The two groups of patients were similar in their PANSS scores, but the homicidal men were significantly more likely to show higher harm avoidance (HA) scores than the less violent comparison men (t = 2,876, df-69, p = 0.005). Conclusions: Our results indicate that forensic schizophrenic patients with higher HA scores would show a greater risk of homicidal violence. Improved understanding of personality traits associated with such behavior is needed in order to prevent homicidal behavior. Importance of these results suggests that further study is needed.

Effect of expectation on pain assessment of lower- and higher-intensity stimuli.

BACKGROUND AND AIMS: Pain modulation via expectation is a well-documented phenomenon. So far it has been shown that expectations about effectiveness of a certain treatment enhance the effectiveness of different analgesics and of drug-free pain treatments. Also, studies demonstrate that people assess same-intensity stimuli differently, depending on the experimentally induced expectations regarding the characteristics of the stimuli. Prolonged effect of expectation on pain perception and possible symmetry in conditions of lower- and higher-intensity stimuli is yet to be studied. Aim of this study is to determine the effect of expectation on the perception of pain experimentally induced by the series of higher- and lower-intensity stimuli. METHODS: 192 healthy participants were assigned to four experimental groups differing by expectations regarding the intensity of painful stimuli series. Expectations of two groups were congruent with actual stimuli; one group expected and received lower-intensity stimuli and the other expected and received higher-intensity stimuli. Expectations of the remaining two groups were not congruent with actual stimuli; one group expected higher-intensity stimuli, but actually received lower-intensity stimuli while the other group expected lower-intensity stimuli, but in fact received higher-intensity ones. Each group received a series of 24 varied-intensity electrical stimuli rated by the participants on a 30° intensity scale. RESULTS: Expectation manipulation had statistically significant effect on pain intensity assessment. When expecting lower-intensity stimuli, the participants underestimated pain intensity and when expecting higher-intensity stimuli, they overestimated pain intensity. The effect size of expectations upon pain intensity assessment was equal for both lower- and higher-intensity stimuli. CONCLUSION: The obtained results imply that expectation manipulation can achieve the desired effect of decreasing or increasing both slight and more severe pain for a longer period of time. Manipulation via expectation before the stimuli series was proven to be effective for pain modulation in the entire series of stimuli which lasted around 10min. The results suggest a potential benefit of manipulating expectations to alleviate emerging pain, since the obtained effects are moderate to large. IMPLICATIONS: It seems that expectation effect is strong enough to "overcome" even the direct effect of stimulus intensity (at least in the low to moderate intensity range), which suggests potential benefits of verbal instructions even in rather painful stimuli.

What leads to high antipsychotic dosing in forensic patients with schizophrenia?

Earlier findings suggest that forensic schizophrenia patients are treated with higher doses of antipsychotics. This practice-based specificity is insufficiently studied, and clinicians' motives regarding this practice remain poorly understood. In this editorial, the authors provide their data on treatment of forensic schizophrenia patients and identify characteristics of psychopathology and previous types of behaviors, including suicidal attempts, as potential reasons for the practice. They also emphasize that "these previous acts" often took place years ago, and suggest that current or recent aggression is unlikely the main reason for dosing, but rather the clinicians' intention to maintain "must remain unaggressive" condition. Therefore, the authors suggest new ideas that may contribute to a better understanding of the specific prescribing patterns in the forensic population and hope that these ideas would be implemented in further well-designed prospective studies.

Effects of Psychological Distance and Need for Cognitive Closure on Impression Formation.

Based on theoretical and empirical similarities between Construal level theory of psychological distance and the Need for cognitive closure (NFC) theory, it could be hypothesized that psychological distance and NFC represent constructs that overlap to some degree. Since both theories describe judgmental behavior in terms of schematic processing, we hypothesized that primacy effect, a schema-driven phenomenon, is strengthened under the heightened NFC and psychological distance. We tested this hypothesis in an impression formation experiment while manipulating psychological distance and measuring NFC. Low NFC and psychological closeness reflect preference for situationally specific, contextually rich information, and therefore their joint effect resulted in reliance on all available information regardless of their position in a sequence. High NFC and psychological distance produced a preference for clear, schematic, stable knowledge, and therefore weighed first information more, which resulted in the primacy effect.

Multimodal analysis of startle type responses.

BACKGROUND AND OBJECTIVE: This article presents a multimodal analysis of startle type responses using a variety of physiological, facial, and speech features. These multimodal components of the startle type response reflect complex brain-body reactions to a sudden and intense stimulus. Additionally, the proposed multimodal evaluation of reflexive and emotional reactions associated with the startle eliciting stimuli and underlying neural networks and pathways could be applied in diagnostics of different psychiatric and neurological diseases. Different startle type stimuli can be compared in the strength of their elicitation of startle responses, i.e. their potential to activate stress-related neural pathways, underlying biomarkers and corresponding behavioral reactions. METHODS: An innovative method for measuring startle type responses using multimodal stimuli and multimodal feature analysis has been introduced. Individual's multimodal reflexive and emotional expressions during startle type elicitation have been assessed by corresponding physiological, speech and facial features on ten female students of psychology. Different startle eliciting stimuli like noise and airblast probes, as well as a variety of visual and auditory stimuli of different valence and arousal levels, based on International Affective Picture System (IAPS) images and/or sounds from International Affective Digitized Sounds (IADS) database, have been designed and tested. Combined together into more complex startle type stimuli, such composite stimuli can potentiate the evoked response of underlying neural networks, and corresponding neurotransmitters and neuromodulators as well; this is referred to as increased power of response elicitation. The intensity and magnitude of multimodal responses to selected startle type stimuli have been analyzed using effect sizes and medians of dominant multimodal features, i.e. skin conductance, eye blink, head movement, speech fundamental frequency and energy. The significance of the observed effects and comparisons between paradigms were evaluated using one-tailed t-tests and ANOVA methods, respectively. Skin conductance response habituation was analyzed using ANOVA and post hoc multiple comparison tests with the Dunn-Sidák correction. RESULTS: The results revealed specific physiological, facial and vocal reflexive and emotional responses on selected five stimuli paradigms which included: (1) acoustic startle probes, (2) airblasts, (3) IAPS images, (4) IADS sounds, and (5) image-sound-airblast composite stimuli. Overall, composite and airblast paradigms resulted in the largest responses across all analyzed features, followed by sound and acoustic startle paradigms, while paradigm using images consistently elicited the smallest responses. In this context, power of response elicitation of the selected stimuli paradigms can be described according to the aggregated magnitude of the participants' multimodal responses. We also observed a habituation effect only in skin conductance response to acoustic startle, airblast and sound paradigms. CONCLUSIONS: This study developed a system for paradigm design and stimuli generation, as well as real-time multimodal signal processing and feature calculation. Experimental paradigms for monitoring individual responses to stressful startle type stimuli were designed in order to compare the response elicitation power across various stimuli. The developed system, applied paradigms and obtained results might be useful in further research for evaluation of individuals' multimodal responses when they are faced with a variety of aversive emotional distractors and stressful situations.

Opinions of forensic schizophrenia patients on the use of restraints: controversial legislative issues.

The use of restraints is a controversial issue even though legal regulations may seem straightforward. Our aims were to evaluate the forensic patients' opinions on certain aspects of restraining and to compare these opinions with the current legal norms. Inpatients with schizophrenia or schizoaffective disorder at the Department of Forensic Psychiatry in Popovaca, Croatia, were asked the following questions about the use of mechanical restraints: (a) Should the patients' family be informed about the use of restraints? (b) Should the physician ask the patient whether to inform the family about the use of restraints? (c) Can the use of restraints be a kind of punishment for intentionally aggressive behavior toward people in their environment? and (d) Should restraints be used if the patient requests to be restrained? The patients were assessed according to the Temperament and character inventory and Positive and Negative Symptom Scale. Fifty-four forensic patients with a history of serious offences were included in the study. Their average age was 44.7 (± 8.39) years and the mean duration of their treatment was 6.6 (± 5.08) years. There was no predominant opinion on sharing the information with the family, but there was a relationship between the opinions and psychopathology and personality. Regardless of the patients' mental state and personality, the opinions on the voluntary use of restraints and the use of restraints as punishment for intentionally aggressive behavior were mainly positive. The patients' opinions suggest a need for the implementation of more specific guidelines in the area of forensic psychiatry.

Offender patients' opinions on placement in a forensic hospital.

BACKGROUND: People who become patients in secure hospitals may not understand their situation and have different opinions about the nature of institutionalisation from each other and from staff and the authorities. More knowledge of patient perspectives could improve treatment outcomes. AIMS: Our aim was to evaluate patients' beliefs about whether placement in an institution should be mainly punitive, therapeutic or a mixture of both and whether offence type should have any influence on the nature of the institutionalisation. METHODS: Inpatients with schizophrenia or schizoaffective disorder, from the Department of Forensic Psychiatry in Popovaca, Croatia, were asked to report their personal opinions about appropriateness of placements according to three case vignettes related to psychotically motivated offences of (1) homicide; (2) property damage; and (3) arson. RESULTS: A total of 52 patients were eligible for participation and consenting. Their average age was 44 (± 9.56) years and the mean duration of treatment in the specialist hospital was 7.7 (± 5.59) years; just over a third of them (20 patients) had committed or attempted homicide. They were more likely than not to favour at least 5 years of detention in a secure hospital for a person with psychosis who had killed another, regardless of mental state, but that for minor property damage, improvement in mental state should be the key determinant of discharge. They were more equivocal about arsonists. CONCLUSIONS: Perceptions of male offenders with psychosis on determinants of length of stay in a secure hospital appear to have much in common with what one would expect in the wider community. The fact that in spite of generally having poor insight into their own situation, these men could make judgments about fictitious but similar patients that appeared so unremarkable raised the possibility of building on this vignette study towards an educationally therapeutic module in preparation for rehabilitation.

Current suicidality and previous suicidal attempts in patients with schizophrenia are associated with different dimensions of temperament and character.

Suicide is a major public health problem and the leading cause of premature death in patients with schizophrenia. Information about the patient's personality is helpful for assessing the risk of suicide attempts and suicidal ideation. The sample consisted of 120 outpatients with a diagnosis of schizophrenia, 29 of whom had previously attempted suicide. We used the Temperament and Character Inventory to assess personality differences between patients who had previously attempted and had not previously attempted suicide and between patients who had and did not have current suicidal ideation. Current suicidal ideation was assessed using the four-point severity scale, which is item nine from the Beck Depression Inventory. The character dimension Self-transcendence was shown by logistic regression to be a predictor of lifetime suicide attempts. Low Self-directedness was shown to be a predictor of current suicidal ideation. To prevent suicidal behaviour, it is important to better understand the personality traits associated with suicidal ideation and suicide attempts. Suicide attempts and suicidal ideation in schizophrenia may not represent the same phenomenon ranging on a single continuum. The importance of these results suggests that further study is needed.

Temperament, character, and quality of life in patients with schizophrenia and their first-degree relatives.

The aim of this study was to investigate the associations between the temperament, character dimensions, and quality of life (QOL) of patients with schizophrenia; their first-degree, nonaffected relatives; and healthy control subjects. One hundred twenty patients, the same number of first-degree relatives, and the same number of control subjects were assessed using the Temperament and Character Inventory and the Quality of Life Enjoyment and Satisfaction Questionnaire. Patients were also assessed using the Positive and Negative Syndrome Scale. Patients and relatives had a significantly lower QOL than control subjects, controlled for temperament and character dimensions. Patients scored significantly higher than control subjects in harm avoidance and self-transcendence and lower in novelty seeking and self-directedness. First-degree relatives had lower results for novelty seeking and scored higher on self-transcendence than control subjects. Harm avoidance, self-directedness, and self-transcendence were the dimensions of Temperament and Character Inventory shown to be the most significant predictors of QOL. Psychopathology and age were also significant predictors of QOL. Our understanding of an individual patient's QOL must include personality evaluation.

Novelty seeking and medication adherence in patients with schizophrenia.

The study explored the association between temperament and character and medication adherence in 76 patients with schizophrenia. Patients were assessed with the Temperament and Character Inventory, the Beck Depression Inventory, and the Positive and Negative Syndrome Scale. First-degree relatives were used as informants on adherence. The patients differed in their adherence based on the effect of gender, as males were found to be less adherent than females. Adherence differed based on novelty seeking. The temperament of the patient should be considered during the assessment of adherence.

Relations of internalized stigma with temperament and character in patients with schizophrenia.

OBJECTIVE: The aim of the study was to assess the associations between self-stigma and temperament and character dimensions. METHODS: One hundred twenty outpatients with diagnosis of schizophrenia, established with Mini International Neuropsychiatric Interview were consecutively included in the study. Self-stigma was assessed with Internalized Stigma of Mental Illness (ISMI), personality dimensions with Temperament and Character Inventory, and psychopathology with Positive and Negative Symptom Scale. RESULTS: The results showed that higher level of harm avoidance, lower self-directedness, and persistence correlated with ISMI and all its subscales. Self-transcendence correlated with ISMI subscales alienation, discrimination, and stigma resistance. Regression analyses controlling for psychopathology, age, length of illness, and number of hospitalizations revealed that higher level of harm avoidance and low self-directedness predicted internalized stigma. CONCLUSION: The finding suggests that the experience of self-stigma is related to personality dimensions. Interpretations of these findings include the possibility that, irrespective of patients' psychopathology or functional characteristics, experience of self-stigma and its consequences might depend on personality dimensions. Further studies are needed.

Sex differences in general knowledge domains.

The aim of this study was to investigate some cognitive differences in highly comparable (according to age, education and motivation) samples of female and male university graduates in Croatia. Female (N=280; age X = 26.59; SD = 2.84) and male participants (N=96; age X = 26.99; SD = 2.99) were university graduates in economics, law humanities and social sciences applying for positions in public service. As part of the selection procedure, they were given a number of cognitive tests. The results were that men obtained higher average scores on the g-factor intelligence test, on the general knowledge tests of natural and social sciences, world religion and customs, and knowledge of current affairs. There were no significant sex differences on vocabulary, foreign language ability and general knowledge of culture. An analysis of covariance, with intelligence test as a covariate, showed that sex differences in general knowledge were present when intelligence was controlled.

Religiosity and quality of life in breast cancer patients.

Our aim was to assess relations between the quality of life and religiosity in breast cancer patients. The participants were 115 consecutively admitted female in-patients with breast cancer in the radiotherapy unit in the course of six months. The measures used were Santa Clara Strength of Religious Faith Questionnaire (SCSORF), World Health Organisation Well-Being Index Five (WHO-WBI 5) and International Breast Cancer Study Group Quality of Life (IBCSG-QL) Questionnaire. The participants responded on three statements relating to religious coping with cancer. Moderate religiosity was associated with perception of worse physical health. The statement "the illness decreased my faith" was associated with worse quality of life (QOL) domains: less well-being, more pain, poor physical health, more effort to cope, worse fatigue and less general satisfaction. The statement "the faith helps me in illness" was associated with higher social support.

Perception of stigmatization in forensic patients with schizophrenia.

BACKGROUND: The literature about perceived stigmatization of forensic patients with schizophrenia is sparse. AIMS: To examine relations between the perceived stigmatization of forensic patients with schizophrenia and the intensity of the symptoms, age, regular home visiting, kind of offence, perceived family support and duration of hospitalization. METHOD: Sixty-two male forensic patients with schizophrenia were included. Perceived stigmatization was measured by the modified questions from the World Health Organization Disability Assessment Schedule II. Symptomatology was assessed with the Positive and Negative Syndrome Scale. Perception of family support was assessed with a visual-analogue scale. Due to different characteristics of offences and possibilities for home visiting, patients were divided into groups of those who had committed violent and non-violent offences, and those with and without the possibility of regular home visiting. RESULTS: Symptoms have an impact on the perception of stigma. The kind of offence committed does not have a significant role in the perception of discrimination. Age was negatively correlated with the perception of stigma. CONCLUSION: Results might have significance for a better understanding of social relations between forensic patients and their environment and provide us with information about institutionalized forms of stigma. Results might have implications for the treatment and the quality of life of these patients.
