This study established the psychometric properties of the Chinese version of the Suicide Intent Scale (SIS) in a clinic‐ and community‐based sample of 36 patients and 592 respondents, respectively. Results showed that the Chinese SIS demonstrated good inter‐rater and test‐retest reliability. Factor analysis generated three factors (Precautions, Planning, and Seriousness) explaining 92.9% of the total variance with high internal consistency. It was moderately correlated with depressive symptoms. Results suggest that the Chinese SIS is a reliable and valid instrument for use in assessing the extent of suicidal intention among subjects with deliberate self‐harm in ethnic Chinese populations. 相似文献

Psychopathology, social support, and interpersonal orientation were studied in relation to suicide attempt status in acutely suicidal, psychiatrically hospitalized Black adolescents and a matched sample of White adolescents. In the total sample, multiple attempters were differentiated by lower perceived support. Within the Black youth subsample, social comparison and positive stimulation from others differentiated multiple attempters from single attempters/ideators. Only suicidal ideation predicted multiple attempts among White youth and only higher interpersonal orientation predicted multiple suicide attempts within Black adolescents. 相似文献

We investigated the association of suicidal ideation and behavior with depression, anxiety, and alcohol abuse in a Canadian Arctic Inuit community. Inuit (N = 111) from a random sample of households completed assessments of anxiety and depression, alcohol abuse, and suicidality. High rates of suicidal ideation within the past week (43.6%), and suicide attempts within last 6 months (30%), were reported. Ideation was more frequent among younger persons, whereas those favoring local native language were less likely to report a wish to die. Higher overall suicidality scores were associated with higher anxiety, and alcohol abuse, but not with depression or gender. Implications for future research are discussed. 相似文献

Non-linear fractal analysis of cardiac interbeat time series was performed in corticotropin-releasing factor receptor subtype
2 (CRFR2) deficient mice. Heart rate dynamics in mice constitutes a self-similar, scale-invariant, random fractal process
with persistent intrinsic long-range correlations and inverse power-law properties. We hypothesized that the sustained tachycardic
response elicited by intraperitoneal (ip) injection of human/rat CRF (h/rCRF) is mediated by CRFR2. In wildtype control animals,
heart rate was increased to about maximum levels (~ 750 bpm) while in CRFR2-deficient animals baseline values were retained
(~ 580 bpm). The tachycardic response elicited by ip-application is mediated by CRFR2 and is interpreted to result from sympathetic
stimulation. However, the functional integrity of CRFR2 would not present a prerequisite to maintaining the responsiveness
and resiliency of cardiac control to external environmental perturbations experimentally induced by extrinsic ip-application
of h/rCRF or under physiological conditions that may be associated with an increased peripheral release of CRF. Under stressful
physiological conditions achieved by novelty exposure, CRFR2 is not involved in the cardiodynamic regulation to external short-term
stress. While the hypothesis of involvement of CRFR2 in cardiac regulation upon pharmacological stimulation cannot be rejected,
the present findings suggest that the mechanism of action is by sympathetic stimulation, but would not unambiguously allow
to draw any conclusions as to the physiological role of CRFR2 in the control of cardiac dynamics. 相似文献
