Clinicians are expected to provide accurate and useful mental health assessments, sometimes in emergency settings. The most urgent challenge may be in calculating suicide risk. Unfortunately, existing instruments often fail to meet requirements. To address this situation, we used a sustainable scale development approach to create a publicly available Suicidality Scale (SS). Following a critical review of current measures, community input, and panel discussions, an international item pool survey included 5,115 English-speaking participants aged 13–82 years. Revisions were tested with two follow-up cross-sectional surveys (Ns = 814 and 626). Pool items and SS versions were critically examined through item response theory, hierarchical cluster, factor and bifactor analyses, resulting in a unidimensional eight-item scale. Psychometric properties were high (loadings > .77; discrimination > 2.2; test-retest r = .87; internal consistency, ω = .96). Invariance checks were satisfied for age, gender, ethnicity, rural/urban residence, first language, self-reported psychiatric diagnosis and suicide attempt history. The SS showed stronger psychometric properties, and significant differences in bivariate associations with depressive symptoms, compared with included suicide measures. The ‘open source’ Suicidality Scale represents a significant step forward in accurate assessment for people aged 13+, and diverse populations. This study provides an example of sustainable scale development utilizing community input, emphasis on strong psychometric evidence from diverse samples, and a free-to-use license allowing instrument revisions. These methods can be used to develop a wide variety of psychosocial instruments that can benefit clinicians, researchers, and the public.
Aim: Interpersonal sensitivity and mistrust are the main characteristics of cluster A personality disorders (CAPD) which might be due to the high accessibility to negative suggestions from environments. Yet the exact associations between hypnotic suggestibility and their personality disorder functioning styles remain unclear. Methods: We invited 36 patients with CAPD and 115 healthy volunteers to undergo the Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C) and Parker Personality Measure (PERM). Results: Compared to controls; patients scored higher on PERM paranoid; schizoid; schizotypal; borderline; avoidant; and dependent styles; on the SHSS:C total and “challenge suggestions”, and the passing rates of “hand lowering”, “arm rigidity”, “dream”, and “arm immobilization”. In patients, “dream” negatively predicted the schizoid; “hallucinated voice” negatively the schizotypal; “mosquito hallucination” positively the histrionic and dependent; and “arm immobilization” negatively the avoidant style. Conclusions: Our results suggested that the insusceptibility to perceptual suggestions from others and the high control over body contribute to the paranoid attitude and interpersonal avoidance in CAPD. These findings help to understand the cause of interpersonal problems in these patients and suggest the trial of hypnotherapy for them.
The sexual dream is partly connected with sexual crimes and affects both physical and psychological well-being of university students, but there is no investigation on the detailed sexual dream experience and the depressive mood in this population in China. Altogether 3,479 students in a comprehensive Chinese university were invited to report their frequency of lifelong sexual dream. The frequent sexual dreamers (sDreamers) and nonfrequent sexual dreamers (controls) were invited to answer the Sexual Dream Experience Questionnaire (SDEQ) and the Plutchik-van Praag Depression Inventory. Altogether 1,481 students reported their lifetime sexual dreams (the prevalence of sexual dream was 42.57%), and 89 were defined as sDreamers (the prevalence of frequent sexual dream was 2.56%), with a male preponderance. Comparisons between sDreamers and the 213 controls have shown that the SDEQ Joyfulness, Familiarity, and Bizarreness scores were elevated in sDreamers. Moreover, Plutchik-van Praag Depression Inventory was correlated with SDEQ Joyfulness and Bizarreness in sDreamers and with Joyfulness in controls. This is the first report in Chinese university students regarding the sexual dream experience and depressive mood, which might help to investigate the emotional state in frequent sexual dreamers.
During the COVID-19 pandemic, Swedish universities had to shift from face-to-face teaching to internet-based distant learning (DL). DL differs from classroom teaching and may have a negative impact on students’ emotions while studying. Students’ experiences related to DL may reflect their personality, resilience, that is, Sense of Coherence (SOC), and preference for the education method. In this study, students’ emotions related to DL and the relationship between personality factors, SOC and positive and negative emotions related to DL were studied. One hundred ninety-seven university students filled in an online survey about positive and negative emotions related to DL, personality factors (Big-5), SOC, frequency of applying COVID-19 distancing measures, and frequency and freedom to choose DL. The survey was completed in March-April 2021 (Sample 1), when all lectures were delivered from a distance and in November 2021 (Sample 2), when lectures were on the campus. There were no differences between the frequency of negative and positive emotions. Agreeableness (Sample 1) and Neuroticism (Sample 2) correlated positively with negative emotions. SOC correlated negatively with negative emotions in Sample 2. In regression analyses of the combined data, Agreeableness was positively and Openness to Experience was negatively related to negative emotions. Agreeableness was negatively and Openness to Experience positively related to positive emotions related to forced DL. DL—even forced one—has both positive and negative effects on students’ emotions. These effects depend on students’ personality characteristics to some degree. SOC might reduce the negative effects of forced distance learning.
Hypersexuality is related to functions of personality and emotion and is a salient symptom of bipolar I disorder especially during manic episode. However, it is uncertain whether bipolar I disorder with (BW) and without (BO) hypersexuality exhibits different cerebral activations under external emotion stimuli. In 54 healthy volunteers, 27 BW and 26 BO patients, we administered the visual oddball event-related potentials (ERPs) under external emotions of Disgust, Erotica, Fear, Happiness, Neutral, and Sadness. Participants’ concurrent states of mania, hypomania, and depression were also evaluated. The N1 latencies under Erotica and Happiness were prolonged, and the P3b amplitudes under Fear and Sadness were decreased in BW; the P3b amplitudes under Fear were increased in BO. The parietal, frontal, and occipital activations were found in BW, and the frontal and temporal activations in BO under different external emotional stimuli, respectively. Some ERP components were correlated with the concurrent affective states in three groups of participants. The primary perception under Erotica and Happiness, and voluntary attention under Fear and Sadness, were impaired in BW, while the voluntary attention under Fear was impaired in BO. Our study indicates different patterns of visual attentional deficits under different external emotions in BW and BO.
