Factors associated with adolescent suicidal gestures [electronic resource] / by Heidi Jennifer Liss.Liss, Heidi Jennifer. January 2003 (has links)
Includes vita. / Title from PDF of title page. / Document formatted into pages; contains 126 pages. / Thesis (Ph.D.)--University of South Florida, 2003. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: Incidence of suicide has been shown to increase dramatically during adolescence. Despite an established pattern of depression and hopelessness leading to suicide in adults, no such pattern emerges in the adolescent literature. Recent investigations suggest that impulsivity may play a key role in adolescent suicide attempts. This study examined the role of impulsivity in adolescent suicidal gestures, as well as the relationships among demographic variables, anger expression, impulsivity, and suicidal behavior. A total of 100 participants (ages 11-17; 71 females and 29 males) were recruited from 2 inpatient crisis centers for children. The Children's Depression Inventory, Hopelessness Scale for Children, Adolescent Behavior Checklist, Pediatric Anger Expression Scale, and Suicide Intent Scale were administered to inpatients, and demographic information was obtained (age, gender, ethnicity, income, and structure of family). / ABSTRACT: It was hypothesized that patterns of depression, anger, hopelessness, and impulsivity would vary by age, gender, ethnicity, and suicidality (e.g., suicidal gesture vs. no gesture). The large majority of hypotheses were not supported. Results are explained in terms of alternative theories for the role of impulsivity in adolescent suicidal gestures. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Natural Course of Adolescent Insomnia: Patterns and ConsequencesRoane, Brandy Michelle 08 1900 (has links)
Approximately 2-11% of adolescents report chronic insomnia. The study used an archival data set from ADDHealth that assessed adolescent health and health-related behaviors. Adolescents (N = 4102) provided data at baseline (Time 1) and at 1-year follow-up (Time 2). Participants were excluded if no ethnicity, gender, or insomnia data were given at Time 1 or 2. Females were more likely to report insomnia than males at Times 1 and 2. In addition, adolescents with remitted insomnia were significantly younger than adolescents without insomnia at Times 1 and 2. Analyses found a prevalence of 9.6%, a remittance of 6.2%, an incidence of 4.4%, and a chronicity of 2.9%. At Time 1 and 2, AWI were significantly more likely to have depression, suicidal behaviors, and behavioral problems in school than AWOI. At Time 2, incidence and chronic insomnia increased the risk of depression, suicidal behaviors and behavioral problems in school. Risk and protective factors analyses indicated psychological counseling was associated with both remitted and chronic insomnia and depression was associated with incidence insomnia.

Psychological antecedents of suicidal behaviorCameron, Shri January 2013 (has links)
While research highlights a number of risk factors for suicide, not all individuals displaying these characteristics will go on to attempt suicide. Depressed mood is a proximal indicator of suicide, with deterioration in already depressed mood increasing the likelihood of a suicide attempt. The overall aim of this thesis was to empirically test the Cognitive Model of Suicide by Wenzel and Beck (2008). This model proposes that each of the three components, dispositional vulnerabilities, mood disturbance and suicide related cognitions, may influence each other to enhance the propensity for a suicidal crisis. The thesis starts by examining the relationship between two personality characteristics (neuroticism and trait aggression) and current depressed mood, and then focuses on the relationship between suicidality and current depressed mood. Although autobiographical memories have been implied as a possible risk factor for suicidality, meta-analytical studies have highlighted discrepancies between sampling techniques which may limit interpretablity. Therefore, the first series of studies aimed to establish a protocol for assessing autobiographical memories. The second and third series of studies aimed to investigate whether the relationships between current depressed mood and specific personality factors (neuroticism and trait aggression) were indirectly influenced by other known risk factors that may affect cognitive processing of information (rumination, overgenerality, impulsivity). Moreover, these studies aimed to determine whether the same cognitive processing factors effected current depressed mood in non-suicidal and suicide attempt groups. The final series of studies aimed to determine whether these risk factors (neuroticism, trait aggression, brooding, impulsivity, and overgenerality) mediated the relationship between suicidality and current depressed mood. Findings indicated that compared to the non-suicidal group, individuals in the suicide attempt group was more likely to be influenced by the effects of trait aggression and brooding, and that the combination of these factors were positively associated with current depressed mood. In contrast, neuroticism and impulsivity appeared to influence individuals who had experienced suicidal ideation more than individuals who report never having suicidal thoughts or attempting suicide. Compared to the non-suicidal group, however, neuroticism and impulsivity did not show a significant association for current depressed mood in the suicidal ideation group. Findings supported the Interacting Sub-Systems model and are discussed in relation to the Cognitive Model of Suicide model.

Psychopathological correlates of risk for adolescents in secure treatmentMcCulloch, Ariana, University of Lethbridge. Faculty of Education January 2005 (has links)
This research utilized data concerning adolescents at imminent risk for harm confined to the Edmonton and Lethbridge secure treatment centres in Alberta. Once screened for inclusion criteria in a single stage, non-random convenience sampling protocol, 210 files were included in the study. From these files, the adolescents' psychopathological diagnoses, Suicide Probability Scale (SPS) scores as well as other demographic data (including age, gender, ethnicity and previous suicide attempts) were recorded. This research was designed to delineate the characteristics of adolescents admitted to secure treatment, examine the overall suicide risk in this sample, investigate the relationship between study variables via crosstabulation and chi-square analysis, and to determine which independent variable/s best predicted suicide risk via ANOVA and multiple lineear regression analysis. Analysis results indicated that the sample was predominantly comprised of female adolescents, Caucasian ethnicity and was aged between 13 and 15 years. The majority of adolescents with suicide history information available in their file had previously attempted suicide. Youth demonstrated an average of 2.7 psychopathological diagnoses, the most frequent of which were conduct disorder, substance abuse, depression, adjustment disorder and parent child relational disorder. The majority of youth were in the moderate suicide risk category from SPS scores. Multiple linear regression analysis determined that the diagnoses of adjustment disorder and depression were found to be predictive of increased suicide risk scores, as was gender (females had higher risk scores), age (younger adolescents had higher risk scores) and previous suicide attempts. Those in the "other" ethnicity category demonstrated lower suicide risk scores. / xi, 193 leaves ; 29 cm.

A test of competing models to predict suicidality in patients and students in Taiwan.Ku, Yung-Li January 2008 (has links)
The aim of this research was to test a series of theoretical models based on Beck (1967) cognitive diathesis-stress and Kwon and Oei (1994) linear mediational models as well as earlier research findings to determine the best-fitting model to explain the aetiological processes of suicide attempts in Taiwanese people. The participants were patients diagnosed with Major Depressive Disorders (MDD) recruited from three hospitals in Taiwan. They were used for data analyses in both cross-sectional (main) study and longitudinal (follow-up) study. In addition, a sample of students recruited from three universities in Taiwan was used for data analyses in the generalized study to examine the generalization of the results from clinical depressed patients to nonclinical university students. In the main study, by the application of structural equation modeling (SEM) techniques, four initial models were compared using the MDD patients (N = 162). The SEM analyses showed that two interactional models failed to provide an adequate fit to the given data, suggesting that the hypothesis of interaction between dysfunctional attitudes and negative life events in predicting the psychopathology of Taiwanese MDD patients was not supported. The SEM analyses supported two mediational models in terms of goodness-of-fit. Because the two mediational models were very similar, they were combined to form a combined mediational model. The SEM analyses indicated that the combined model provided an adequate fit to the given data. After modifying the model to improve its goodness-of-fit, the final modified combined mediational model was selected as the most appropriate in representing the data of Taiwanese MDD patients. The final model revealed that dysfunctional attitudes mediated the relationship between negative life events and depressive hopelessness, which in turn increased depression, which then precipitated suicidal ideation, which finally resulted in suicide attempts. In addition, it was found that negative life events exerted direct influences on depressive hopelessness and suicide attempts; sex and age exerted direct influences on negative life events. However, social support buffered the impact of negative life stress on dysfunctional attitudes and compliance with medications prevented the development of depression. In the follow-up study, the final modified combined mediational model was validated and reexamined with two-wave panel data gathered from the same population of Taiwanese MDD patients who participated in assessments twice, separated by a six-month interval (N = 142). The SEM analyses showed that the model provided an adequate fit to the two-wave panel data, suggesting that the model can be applied for predicting suicide attempts over six months in Taiwanese MDD patients. In the generalized study, the findings obtained from the MDD patients were replicated in a sample of Taiwanese university students (N = 324). Results revealed that the final modified combined mediational model failed to fit the given data. The result suggests that the most appropriate model for Taiwanese MDD patients can not be generalized to Taiwanese students. Some cautions and limitations should be noted. First, the models obtained from clinical and nonclinical people in Taiwan should not be directly generalized to people outside Taiwan. Further research using clinical and nonclinical samples from other countries to cross-validate the models was suggested. In addition, the researcher’s interventions during the follow-up period may disturb the relationship between predictor variables and subsequent suicide attempts. However, the problems appear to be unavoidable because of the research ethics of protecting participants from suicidal risk. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1339675 / Thesis (Ph.D.) - University of Adelaide, School of Psychology, 2008

Suicidal behaviour of high school students : attempts, ideation and risk factors of South African and German adolescentsSommer, Marc 30 November 2005 (has links)
The present study compared the suicidal behaviour and related measures of adolescents in high school in Germany (N=318) and South Africa (N=299). Participants completed a series of self-report measures of the SPS (Suicide Probability Scale), PSS-Fa (Perceived Social Support From Family Scale), PSS-Fr (Perceived Social Support From Friends Scale), SIB (Scale Of Interpersonal Behaviour) and a number of demographic questions. Analyses were conducted using content analysis, correlation coefficients and logistic regression to determine variables related to previous suicide attempts, stepwise multiple regression to account for variables predicting currents suicidal risk; and multivariate analysis of variance (MANOVA) to examine differences among the groups and among suicide attempters and non-attempters. 36 German (11.3%) and 48 South African (16.1%) adolescents reported that they had made previous suicide attempts. German adolescents reported 45 (14.2%) suicide attempts in the family and 82 (25.8%) suicide attempts by friends. South African adolescents reported 43 (14.4%) suicide attempts in the family and 92 (30.7%) suicide attempts by friends. The following variables were associated with previous suicide attempts in the German sample: attempted suicide by friends, a life-threatening event, previous psychiatric contact, the death of a friend, low perceived family support, female gender, attempted suicide in the family, suicide of a friend, and low perceived friend support. The following variables were associated with previous suicide attempts in the South African sample: low perceived family support, death of a friend, attempted suicide by friends, female gender, a life-threatening event, previous psychiatric contact, suicide of friends, and attempted suicide in the family. The following variables for the German sample were found to be significant predictors of current suicidal risk: low perceived family and friend support, previous suicide attempts, suicide attempts in the family, a life-threatening event, suicide attempts of friends, suicide of friends, female gender, and previous psychiatric contact. The following variables for the South African sample were found to be significant predictors of current suicidal risk: previous suicide attempts, low perceived family and friend support, death of a friend, a life-threatening event, previous psychiatric contact, suicide attempts in the family, suicide of friends, and suicide attempts of friends. These findings show that suicidal behaviour is frequent in both countries. Suicidal deaths of friends and family is more prevalent in Germany, whereas religion or belief in god does not protect against suicide attempts in both countries. Results indicate that perceived support from family is a strong protective factor against suicide attempts. / Psychology / M.A. (Psychology)

Exploration of the factors contributing to suicidal ideation among police officers in Vhembe District, Limpopo Province, South AfricaSingo, Constance 18 May 2019 (has links)
MPH / Department of Public Health / Over the past years, suicide and suicidal ideation are being increasingly recognised as important issues for public health policy, especially, among police officers. Suicidal ideation is one of the tragic issues among police officers, causing serious emotional, spiritual, medical, social and psychological distress for the individual, their families and friends, however, not much is known about it in the Vhembe District.
The purpose of the study was to explore the factors contributing to suicidal ideation among police officers in Vhembe District. The study was conducted in the Thohoyandou cluster, which is situated in Limpopo Province, South Africa. A study had a qualitative phenomenological research design. The data saturation were reached at the number of 12 police officers, the target population were selected by means of convenience sampling and data was collected through a semi-structured interview. The data collected was analysed using the thematic analytical approach and conclusion were made based on the findings of the study.
The study findings show the following as the factors contributing to suicidal ideation among the police officers - domestic violence, financial problems, divorce, extramarital affairs, lack of social support, health problems, contradicting the law and organisational factors that include organisational structure and working with guns.
The study recommended that the South African Police Services should continue to provide support and counselling to police officers after they have attended to traumatic cases and that police officers need to be more open about their problems and avoid attempting to deal with them by themselves. / NRF
