Significant Predictors Of Suicidal Ideation Research Articles

Predictors of suicidal ideation in older individuals receiving home‐care services

Despite the importance of tending to older individuals who are vulnerable to suicide, little is known about suicidal ideation in the portion of this population receiving home-care services in Asian countries. The objective of this cross-sectional study was to examine predictors of suicidal ideation in older individuals using home-care service. Participants were randomly selected from the individuals 50 years old and over using home-care services across Jeollabuk-do Province, Korea. A total of 697 subjects participated in this study. Each participant completed the short version of the Geriatric Depression Scale, the Scale for Suicidal Ideation, the Multidimensional Scale of Perceived Social Support, and the World Health Organization Disability Assessment Schedule II. Hierarchical regression analyses revealed that depression, perceived social support, and disability were significant predictors of suicidal ideation, whereas the roles of subjective health status and fish consumption remained ambiguous in this regard. In terms of social support, we also found that less perceived social support from family members was related to higher levels of suicidal ideation. The associations between various categories of disability and suicidal ideation disappeared after controlling for depression. Our investigation of the mediating effect of depression on the relationship between disability and suicidal ideation revealed that depression was either a complete (disability related to cognition, self-care, getting along with others, and life activities) or partial (disability related to participation) mediator. Preventive strategies focusing on depression, social support, and disability should be emphasized during encounters with older people receiving home-care services.

Associations between emotional intelligence, depression and suicide risk in nursing students

The most important factor which predisposes young people to suicide is depression, although protective factors such as self-esteem, emotional adaptation and social support may reduce the probability of suicidal ideation and suicide attempts. Several studies have indicated an elevated risk of suicide for health-related professions. Little is known, however, about the relationship between perceived emotional intelligence and suicide risk among nursing students. The main goals were to determine the prevalence of suicide risk in a sample of nursing students, to examine the relationship between suicide risk and perceived emotional intelligence, depression, trait anxiety and self-esteem, and to identify any gender differences in relation to these variables. Cross-sectional study of nursing students (n=93) who completed self-report measures of perceived emotional intelligence (Trait Meta-Mood Scale, which evaluates three dimensions: emotional attention, clarity and repair), suicide risk (Plutchik Suicide Risk Scale), self-esteem (Rosenberg Self-esteem Scale), depression (Zung Self-Rating Depression Scale) and anxiety (Trait scale of the State-Trait Anxiety Inventory). Linear regression analysis confirmed that depression and emotional attention are significant predictors of suicidal ideation. Moreover, suicide risk showed a significant negative association with self-esteem and with emotional clarity and repair. Gender differences were only observed in relation to depression, on which women scored significantly higher. Overall, 14% of the students were considered to present a substantial suicide risk. The findings suggest that interventions to prevent suicidal ideation among nursing students should include strategies to detect mood disorders (especially depression) and to improve emotional coping skills. In line with previous research the results indicate that high scores on emotional attention are linked to heightened emotional susceptibility and an increased risk of suicide. The identification and prevention of factors associated with suicidal behaviour in nursing students should be regarded as a priority.

The glass half-full or a hopeful outlook: Which explains more variance in interpersonal suicide risk in a psychotherapy clinic sample?

Recent research has suggested that constructs in the field of positive psychology may be important for understanding suicide risk. Specifically, both hope theory and dispositional optimism have been linked to lower levels of suicidal ideation and interpersonal suicide risk. Despite these encouraging findings, no study has investigated the relationships between hope, optimism, and suicide risk in a clinical sample. The current study aimed to address this gap and to determine if hope or optimism was more important for understanding suicide risk as operationalized by the interpersonal-psychological theory and suicidal ideation. Results of hierarchical regression analyses revealed that both hope and optimism predicted lower levels of burdensomeness and thwarted belongingness, but were not significant predictors of suicidal ideation. Further, results revealed that when both hope and optimism were entered into a hierarchical regression in the final step, only optimism remained significant. Theoretical and clinical implications of these findings are discussed.

Chronic pain and the interpersonal theory of suicide.

Chronic pain is a known risk factor for suicide. To date, however, few studies of people with chronic pain have tested specific predictions about suicidal ideation that are derived from theory. The interpersonal theory of suicide proposes that the psychological constructs of thwarted belongingness and perceived burdensomeness are unique and independent precursors to suicidal ideation. We tested this hypothesis in a clinical sample of patients with chronic pain. A total of 303 patients of a chronic pain rehabilitation program completed measures of pain severity, duration, and disability; cognitive-affective measures of depression and catastrophizing; and interpersonal measures of relationship distress and self-perceived burden to others. The latter measures were included as indices of the belongingness and burdensomeness constructs. Participants also rated two items pertaining to suicidal ideation. In a multiple regression analysis, both distress in interpersonal relations (β = 0.12, p = .037) and self-perceived burden to others (β = 0.25, p < .001) were significant predictors of suicidal ideation, even after adjusting statistically for demographic characteristics, pain severity and duration, functional limitations, catastrophizing, and depression. These findings suggest that the interpersonal theory is relevant to understanding elevated rates of suicidal ideation among people with chronic pain, and may have broader applicability to other populations with chronic illness or disability.

2047 – Suicidal behaviour in stress disorder

Aims To examine the predictors of suicidal ideation and self-harm in patients diagnosed with a depressive episode or an adjustment disorder, and to examine any difference in these predictors between the two diagnostic categories. Methods Patients referred to the liaison psychiatry services at two Dublin hospitals and diagnosed with either a depressive episode or an adjustment disorder were recruited to this study. They were interviewed at time of diagnosis, and again after six months, with a number of validated instruments to examine levels of suicidality or self-harm and their relationship to depressive symptoms, life events, social functioning and personality factors. Results 300 patients were recruited to the study, 154 of whom had a diagnosis of an adjustment disorder and the remainder diagnosed with a depressive episode. On univariate analysis there was no significant difference in the rates of suicidal ideation between the diagnoses of depressive episode and adjustment disorder. On logistic regression there were no significant predictors of suicidal ideation in adjustment disorder. A single marital status and low levels of social support were more predictive of suicidality in the subgroup with a diagnosis of depression. Conclusions There has been little prior research into the predictors of suicidal behaviour in patients with diagnoses of depression and adjustment disorders. Our finding that social support and marital status are protective against suicidality in this population is in keeping with the literature. The absence of any significant contribution of the severity of depressive symptoms to suicidality was unexpected.

Factors Affecting on Suicidal Ideation in Maladjusted Soldiers

Purpose: The purpose of this study was to explore levels of depression, anxiety, suicidal ideation in maladjusted Korean soldiers and identify factors that influence suicidal ideation. Methods: Instruments were the CES-D (Center for Epidemiologic Studies-Depression Scale), STAI (State Trait Anxiety Inventory), and SSI (Scale for Suicidal Ideation). The participants were 94 maladjusted soldiers from one army base in Gyeong-gi Province. Data were collected using self-report questionnaires, and analyzed with the SPSS/WIN 20.0 program. Results: Mean scores were; for CES-D, 42.1±13.10, for STAI-I (state-anxiety) and STAI-II (trait-anxiety), 60.3±15.05 and 61.9±12.14 respectfully, and for SSI, 23.1±9.52. There were significant differences in suicidal ideation according the general characteristics of education, prospects for the future, and having someone to talk about troubles. Major variables showing significant correlations were prospects for the future, depression, trait anxiety, state anxiety, and suicidal ideation. Depression and prospect for future were significant predictors of suicidal ideation (Adjusted R 2 65%). Conclusion: Based on the findings of this study, it is important to assess significant mental health problems at the clinical level and provide suicidal ideation prevention in maladjusted soldiers. Active input from experts such as nursing officers and intervention programs that focus on depression are needed.

Guilt is more strongly associated with suicidal ideation among military personnel with direct combat exposure

BackgroundSuicide rates in the U.S. military have been rising rapidly in the past decade. Research suggests guilt is a significant predictor of suicidal ideation among military personnel, and may be especially pronounced among those who have been exposure to combat-related traumas. The current study explored the interactive effect of direct combat exposure and guilt on suicidal ideation in a clinical sample of military personnel. MethodsNinety-seven active duty U.S. Air Force personnel receiving outpatient mental health treatment at two military clinics completed self-report symptom measures of guilt, depression, hopelessness, perceived burdensomeness, posttraumatic stress disorder, and suicidal ideation. ResultsGeneralized multiple regression analyses indicated a significant interaction of guilt and direct combat exposure (B=.124, SE=.053, p=.020), suggesting a stronger relationship of guilt with suicidal ideation among participants who had direct combat exposure as compared to those who had not. The interactions of direct combat exposure with depression (B=.004, SE=.040, p=.926), PTSD symptoms (B=.016, SE=.018, p=.382), perceived burdensomeness (B=.159, SE=.152, p=.300) and hopelessness (B=.069, SE=.036, p=.057) were nonsignificant. ConclusionsAlthough guilt is associated with more severe suicidal ideation in general among military personnel, it is especially pronounced among those who have had direct combat exposure.

Examining the Association between Psychiatric Illness and Suicidal Ideation in a Sample of Treatment-Seeking Canadian Peacekeeping and Combat Veterans with Posttraumatic Stress Disorder

Our study examines the association between suicidal ideation and and self-reported symptoms of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), generalized anxiety disorder (GAD), and alcohol use disorder (AUD) in a sample of treatment-seeking Canadian combat and peacekeeping veterans; and identifies potential predictors of suicidal ideation. Actively serving Canadian Forces and Royal Canadian Mounted Police members and veterans seeking treatment at the Parkwood Hospital Operational Stress Injury Clinic (n = 250) completed measures including the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire, the Alcohol Use Disorder Identification Test, and the PTSD Checklist-Military Version (PCL-M) between January 2002 and December 2010. Regression analyses were used to determine the respective impact of PTSD, and self-reported symptoms of MDD, GAD, AUD, and anxiety on suicidal ideation. Most people met PCL-M screening criteria for PTSD (73.6%, n = 184), while 70.8% (n = 177) screened positively for a probable major depressive episode. PTSD symptom was significantly associated with suicidal ideation (β = 0.412, P < 0.001). After controlling for self-reported depressive symptom severity, AUD severity, and generalized anxiety, PTSD severity was no longer significantly associated with suicidal ideation (β = 0.043, P = 0.58). Although PTSD alone is associated with suicidal ideation, after controlling for common comorbid psychiatric illnesses, self-reported depressive symptom severity emerged as the most significant predictor of suicidal ideation. These findings support the importance of screening for comorbidities, particularly an MDD, as potentially modifiable conditions that are strongly related to suicidal ideation in military personnel's endorsing criteria for PTSD.

Predictors for suicidal ideation after occupational injury

Risk of suicide has been associated with trauma and negative life events in several studies. Our aim was to investigate the prevalence and risk factors of suicidal ideation, and the population attributable risk among workers after occupational injuries. We investigated workers who had been hospitalized for ≧3days after occupational injuries between February 1 and August 31, 2009. A self-reported questionnaire including demographic data, injury condition, and the question of suicidal ideation was sent to 4498 workers at 3months after their occupational injury. A total of 2001 workers (45.5%) completed the questionnaires and were included in final analysis. The prevalence of reporting suicidal ideation was 8.3%. After mutual adjustment, significant risk factors for suicidal ideation higher than “serious” in a self-rated severity scale (adjusted odds ratio, aOR=2.31; adjusted population attributable risk, aPAR=34.7%), total hospital stay for 8days or longer (OR=1.98; aPAR=20.5%), intracranial injury (OR=2.30; aPAR=10.2%), and marriage status of being divorced/separated/widowed (OR=2.70; aPAR=10.0%). Three months after occupational injury, a significant proportion of workers suffered from suicidal ideation. Significant predictors of suicidal ideation after occupational injury included broken marriage, intracranial injury, injury severity, and total hospital stay. Identification of high risk subjects for early intervention is warranted.

Perceived Family Functioning and Suicidal Ideation

: Suicidal ideation has been identified increasingly as a problem among university students in Hong Kong. Understanding the relationships among hopelessness, perceived family functioning, and suicidal ideation is essential to designing effective interventions. : The aims of this study are to explore the relationships among hopelessness, perceived family functioning, and suicidal ideation and to examine the moderating and mediating roles played by hopelessness on suicidal ideation. : A cross-sectional survey using convenience sampling was conducted. A questionnaire was administered to 350 university students with ages 18 to 25 years. The questions measured levels of suicidal ideation, perceived family functioning, and hopelessness of the students. Data analyses, including correlation and multiple hierarchical regression analyses, were conducted to examine the mediating and moderating roles of hopelessness on suicidal ideation. : Perceived family functioning (B = -.10, p < .05) and hopelessness (B = .56, p < .001) were shown to be significant predictors of suicidal ideation. Hopelessness was found to mediate only partially but moderate the impact of perceived family functioning on suicidal ideation (B = -.88, p < .05), hence expanding Beck's cognitive theory of suicide. : Perceived family functioning and hopelessness are significant predictors, whereas hopelessness is a partial mediator and a significant moderator of suicidal ideation. Therefore, interventions that enhance family functioning and lower the sense of hopelessness may be effective in decreasing suicidal ideation among university students.

Relationships between suicidal ideation and the dimensions of depressive symptoms among middle-aged population in Japan

The rate of suicides markedly increased in 1998 and leveled off at approximately 30,000 per year thereafter. The aim of the current study was to evaluate the link between the different dimensions of depressive symptoms and suicidal ideation among the middle-aged population in Japan. A sample of 6848 middle-aged (40-60years of age) working individuals completed the Center for Epidemiological Studies Depression Scale (CES-D) and a questionnaire measuring suicidal ideation. The responses on the four dimensions of depressive symptoms on the CES-D (depressed affect, lack of positive affect, somatic symptoms, and interpersonal problems) were entered into regression analyses that predicted the presence of suicidal ideation among the participants with probable depression (n=1704). The factor score of depressed affect was significantly higher in females than in males, whereas that of interpersonal problems was significantly higher in males than in females. Among both males and females, depressed affect was a significant predictor of suicidal ideation. Among males, interpersonal problems also significantly predicted suicidal ideation. Contrary to the results of a previous study among adolescents, we did not find a relationship between lack of positive affect and suicidal ideation. These findings indicate that the dimensions of depressive symptoms measured with the CES-D make different contributions to suicidal ideation. Although our results could not be generalizable to a clinical setting due to lacking clinical samples, the depressed affect dimension of CES-D might be useful for screening of suicide risk among community population. Furthermore, gender differences in the relationships between the dimensions of depressive symptoms in a middle-aged population were identified. Additional studies are needed to examine gender-specific relationships between the dimensions of depressive symptoms and suicidal ideation.

Suicidal ideation in Huntington disease: The role of comorbidity

Huntington disease (HD) is a neurodegenerative condition characterized by cognitive impairments, motor abnormalities, and psychiatric disturbance. An increased risk for suicide has been documented. The majority of HD research has focused on cognitive and motor features of HD; the implications of psychiatric manifestations have received less consideration. Recent studies have sought to identify the stages of HD in which patients are at increased risk to experience suicidal ideation, though no study has examined possible risk factors for suicidality. The current study examines the presence of psychiatric comorbidity and its involvement in suicidal ideation. Suicidal ideation was examined in 1941 HD patients enrolled in the Huntington Study Group. Of those, 19% (N=369) endorsed current suicidal ideation. Logistic regression analyses indicated that depression/anxiety and aggression/irritability are significant predictors of suicidal ideation. In a subsample with the greatest suicidal ideation, alcohol and drug abuse were also predictive. It is recommended that all individuals with HD (specifically those with features of depression, aggression, substance abuse) have routine suicide assessment; further research is needed to understand the high rate of suicide in HD.

Childhood Adversity and Suicidal Ideation in a Clinical Military Sample: Military Unit Cohesion and Intimate Relationships as Protective Factors

Suicide risk and protective factors among 5,187 active duty service members who presented for services at a military outpatient behavioral health clinic were examined. Results indicated that childhood adversity was a significant predictor of suicidal ideation even after controlling for legal, work, financial, and relationship problems, and psychiatric disorders (alcohol abuse, depression, and posttraumatic stress disorder). Childhood adversity was significantly higher among service members who reported prior suicide attempts as compared with service members who did not report prior suicide attempts. The presence of an intimate partner was inversely associated with suicidal ideation. Military unit support moderated the relation between childhood adversity and suicidal ideation, such that this association was positive at lower, but not higher, levels of unit support.

Prädiktoren suizidalen Verhaltens bei Bundeswehrsoldaten

Increasing psychological distress due to out-of-area deployments is associated with a growing risk of suicidal behaviour in soldiers. A total of 200 military psychiatric inpatients of German Armed Forces hospitals, including n=100 soldiers with and n=100 without (control group) acute suicidality prior to admission were compared concerning sociodemographic and clinical characteristics. Significant predictors of suicidal ideation were a family history of alcohol abuse and pathological scales of the Minnesota Multiphasic Personality Inventory (MMPI). Suicide attempts were predicted by pathological MMPI scales, insufficient occupational education, family history of suicide attempts and the situation of basic military training. Significant predictors of suicidal ideation were a family history of alcohol abuse and pathological scales of the Minnesota Multiphasic Personality Inventory (MMPI). Suicide attempts were predicted by pathological MMPI scales, insufficient occupational education, family history of suicide attempts and the situation of basic military training.

Predictors of Suicidal Ideation among Palliative Care Patients (747)

1.Review literature on predicators of suicidal ideation among advanced cancer patients.2.Discuss the impact of abuse history and depression on suicidal ideation among advanced cancer patients. I. Background. Previous research suggests that pain interference with activities, depression, and limited social support predict desire for hastened death among patients with advanced cancer. II. Research Objectives. This study examines the impact of multiple predictors on suicidal ideation including pain interference, depression, limited social support, financial stress, and history of physical, emotional, or sexual abuse. III. Methods. Two hundred seventy-one consecutive new palliative care outpatients completed the Brief Pain Inventory (BPI), and an Initial Psychosocial Pain Assessment that included the DSM-IV criteria for depression. Performed by a licensed clinical psychologist, the interview assessed patient history of physical, emotional, or sexual abuse (yes/no), patient level of support (limited vs. good or excellent), and patient financial difficulties (none vs. limited/very limited). The logistic regression included abuse history and support (Step 1), financial distress (Step 2), BPI pain severity and interference (Step 3), and DSM-IV-TR Major Depression (Step 4) regressed onto suicidal ideation (yes/no). IV. Results. Eighteen percent (n=69) of patients reported thinking about ending their life. Twenty-three percent of those expressing suicidal ideation reported an actual plan for ending their lives, but only 2 people (3%) expressed intent requiring emergent intervention. There was no relationship between suicidal ideation and age, race, gender, education, employment status, or disease status. Abuse history (Wald=5.20, P=.023) and depression (Wald=8.88, P=.003) were significant predictors of suicidal ideation. Patients were two and six times more likely to report suicidal ideation if they had a history of abuse or major depression. V. Conclusion. Palliative care patients with depression and abuse histories are at greater risk for suicidal ideation. VI. Implications for Research, Policy, or Practice. Implications for this study point to a need for depression and abuse history screening among advanced cancer patients as well as close monitoring for suicidal ideation among patients with increased risk.

Cognitive, Emotive, and Cognitive-Behavioral Correlates of Suicidal Ideation among Chinese Adolescents in Hong Kong

Utilizing Daniel Goleman's theory of emotional competence, Beck's cognitive theory, and Rudd's cognitive-behavioral theory of suicidality, the relationships between hopelessness (cognitive component), social problem solving (cognitive-behavioral component), emotional competence (emotive component), and adolescent suicidal ideation were examined. Based on the responses of 5,557 Secondary 1 to Secondary 4 students from 42 secondary schools in Hong Kong, results showed that suicidal ideation was positively related to adolescent hopelessness, but negatively related to emotional competence and social problem solving. While standard regression analyses showed that all the above variables were significant predictors of suicidal ideation, hierarchical regression analyses showed that hopelessness was the most important predictor of suicidal ideation, followed by social problem solving and emotional competence. Further regression analyses found that all four subscales of emotional competence, i.e., empathy, social skills, self-management of emotions, and utilization of emotions, were important predictors of male adolescent suicidal ideation. However, the subscale of social skills was not a significant predictor of female adolescent suicidal ideation. Standard regression analysis also revealed that all three subscales of social problem solving, i.e., negative problem orientation, rational problem solving, and impulsiveness/carelessness style, were important predictors of suicidal ideation. Theoretical and practice implications of the findings are discussed.

Sleep problems and suicidality in the National Comorbidity Survey Replication

Objective Links between sleep problems and suicidality have been frequently described in clinical samples; however, this issue has not been well-studied in the general population. Using data from a nationally representative survey, we examined the association between self-reported sleep difficulties and suicidality in the United States. Methods The WHO Composite International Diagnostic Interview was used to assess sleep problems and suicidality in the National Comorbidity Survey Replication (NCS-R). Relationships between three measures of sleep (difficulty initiating sleep, maintaining sleep, early morning awaking), and suicidal thoughts, plans, and attempts were assessed in logistic regression analyses, while controlling for demographic characteristics, 12-month diagnoses of mood, anxiety and substance use disorders, and chronic health conditions. Results In multivariate models, the presence of any of these sleep problems was significantly related to each measure of suicidality, including suicidal ideation (OR = 2.1), planning (OR = 2.6), and suicide attempt (OR = 2.5). Early morning awakening was associated with suicidal ideation (OR = 2.0), suicide planning (OR = 2.1), and suicide attempt (OR = 2.7). Difficulty initiating sleep was a significant predictor of suicidal ideation and planning (ORs: 1.9 for ideation; 2.2 for planning), while difficulty maintaining sleep during the night was a significant predictor of suicidal ideation and suicide attempts (ORs: 2.0 for ideation; 3.0 for attempt). Conclusions Among community residents, chronic sleep problems are consistently associated with greater risk for suicidality. Efforts to develop comprehensive models of suicidality should consider sleep problems as potentially independent indicators of risk.

Suicidal Ideation among Canadian Youth: A Multivariate Analysis

A multivariate model was developed incorporating various socio-demographic, social-environmental, and social-psychological factors in an attempt to predict suicidal ideation among Canadian youth. The main research objective sought to determine what socially based factors elevate or reduce suicidal ideation within this population. Using data from the National Longitudinal Study of Children and Youth–Cycle 5 (2003), a cross-sectional sample of 1,032 was used to empirically identify various social determinants of suicidal ideation among youth between the ages of 12 and 15. Results reveal statistically significant correlations between suicide ideation and some lesser examined socially based measures. In particular, ability to communicate feelings, negative attachment to parents/guardians, taunting/bullying or abuse, and presence of deviant peers were significant predictors of suicidal ideation. As expected, depression/anxiety, gender, and age were also correlated with thoughts of suicide. Research findings should help foster a better understanding toward the social elements of suicide and provide insight into how suicide prevention strategies may be improved through an increased emphasis on substance use education, direct targeting of dysfunctional families and deviant peer groups, and exploring more avenues of self-expression for youth.

Psychosocial and Cultural Correlates of Suicidal Ideation Among American Indian Early Adolescents on a Northern Plains Reservation

Although research has increased concerning the psychological and social correlates of American Indian adolescent suicidal ideation, little is known about the precursors to suicidal ideation with the early adolescent age group. In this study, we examined a number of cognitive, behavioral, and emotional correlates of suicidal ideation among 122 American Indian middle school youth who lived on a reservation in the Northern Plains area of the United States in February 2006. The participants were on average 12.4 years old, and about 20% reported that they had made a nonfatal suicide attempt at some time in their lives. When using a multivariate model (adjusted R 2 of .70), depression and substance use were the only significant predictors of suicidal ideation as measured by the Suicidal Ideation-JR scale (Reynolds, 1988). We suggest potential ways in which variables such as gender, friend and family member suicidal behavior, and engagement in traditional activities may affect suicidal ideation through their effects on depression and substance use. We recommend that suicide prevention programs with American Indian early adolescents draw on cognitive-behavioral interventions emphasizing the strengths of select cultural tenets in tandem with substance abuse prevention strategies that appear promising.

Predictors of Suicidal Ideation for Adolescents by Gender

The purposes of this study were 1) to examine the differences in suicidal ideation and psychological variables by gender, 2) compare the contribution of demographic-behavioral variables and psychosocial variables in explaining the variance in suicidal ideation, and 3) identify the most important predictors of suicidal ideation for male adolescents and female adolescents. The subjects consisted of 271 male adolescents and 230 female adolescents. Data were collected through self-report questionnaires, which were constructed to include SSI-C, DEP subscale of the SCL-90-R, PACI, and SWLS. The data were analyzed by the SPSS/WIN program. Suicidal ideation differed by gender. Depression and family communication differed by gender. The unique contribution of demographic-behavioral variables and psychosocial variables in explaining the variance in suicidal ideation differed between male adolescents and female adolescents. The significant predictors of suicidal ideation for male adolescents were life satisfaction, depression, and family communication, explaining 28% of the variance in suicidal ideation. The significant predictors of suicidal ideation for female adolescents were depression, smoking, and life satisfaction, explaining 38% of the variance in suicidal ideation. The findings of this study suggest that the approach to effective suicide prevention program for adolescents should consider gender differences.
