Insomnia Symptoms,Nightmares, and Suicide Risk: Duration of Sleep Disturbance Matters

Duration of insomnia symptoms or nightmares was investigated to see if it was related to suicide risk independent of current insomnia symptoms, nightmares, anxiety symptoms, depressive symptoms, and posttraumatic symptoms. The cross‐sectional study involved analyses of survey responses from undergraduate students who endorsed either insomnia symptoms (n = 660) or nightmares (n = 312). Both insomnia symptom and nightmare duration were significantly associated with suicide risk independent of current insomnia symptoms or nightmares, respectively. Relations were also significant after controlling for anxiety symptoms, depressive symptoms, and posttraumatic symptoms. Results suggest that duration of sleep disturbance is relevant when assessing suicide risk.     

Treatment of Depression and Suicide in Older Adults

This article describes a cognitive behavior therapy (CBT) intervention for suicide prevention in older adults. Although many studies have found that CBT interventions are efficacious for reducing depressive symptoms in the elderly, researchers have yet to evaluate the efficacy of such interventions for preventing suicide or reducing suicide risk in older adults. In this article we describe a 12-session CBT protocol for reducing depression, suicide ideation, and other risk factors of late-life suicide. The following aspects of the treatment are described: assessing suicide risk, conceptualizing the problem through a cognitive behavioral framework, developing a safety plan, increasing hope and reasons for living, improving social resources, improving problem-solving skills and efficacy, improving adherence to medical regimen, and relapse prevention. In addition, we review other behavioral and cognitive strategies such as activity scheduling and cognitive restructuring that are commonly associated with CBT interventions for depression. We illustrate the application of these strategies through the use of case examples.     

Why might poor sleep quality lead to depression? A role for emotion regulation

Disordered sleep is strongly linked to future depression, but the reasons for this link are not well understood. This study tested one possibility – that poorer sleep impairs emotion regulation (ER), which over time leads to increased depressive symptoms. Our sample contained individuals with a wide range of depression symptoms (current depression, N?=?54, remitted depression, N?=?36, and healthy control, N?=?53), who were followed clinically over six months and reassessed for changes in depressive symptom levels. As predicted, maladaptive ER mediated both cross-sectional and prospective relationships between poor sleep quality and depression symptoms. In contrast, an alternative mediator, physical activity levels, did not mediate the link between sleep quality and depression symptoms. Maladaptive ER may help explain why sleep difficulties contribute to depression symptoms; implications for interventions are discussed.     

Suicide and African American teenagers: risk factors and coping mechanisms

In this study we investigated whether locus of control, hopelessness, and depression were primary risk factors for suicide ideation and attempts in African American youth, and whether congruency between locus of control and religious coping style reduced suicide risk. The sample consisted of 176 African American high school students (115 females; 61 males). Multiple and logistic regression were used to determine relationships among study variables. Depression was found to mediate the relationship between hopelessness and suicidal behaviors. External locus of control led to greater risk for hopelessness and depression, with a trend in the predicted direction for suicide attempts. Religious coping style alone was not always associated with reduction of risk of suicidal behaviors, yet some evidence suggests that congruency between locus of control and religious coping style reduces risk. Results provide additional support for suicide interventions to target depressive symptoms. Results also highlight the importance of examining the role of culturally salient variables such as fatalism and religious coping style when developing intervention programs for suicide.     

Positive and Negative Expectations of Hopelessness as Longitudinal Predictors of Depression,Suicidal Ideation,and Suicidal Behavior in High‐Risk Adolescents

The relationship between hopelessness and depression in predicting suicide‐related outcomes varies based on the anticipation of positive versus negative events. In this prospective study of adolescents at elevated risk for suicide, we used two Beck Hopelessness Scale subscales to assess the impact of positive and negative expectations in predicting depression, suicidal ideation, and suicidal behavior over a 2‐ to 4‐year period. In multivariate regressions controlling for depression, suicidal ideation, and negative‐expectation hopelessness, positive‐expectation hopelessness was the only significant predictor of depressive symptoms and suicidal behavior. Clinical interventions may benefit from bolstering positive expectations and building optimism.     

Exercise and Diet as Potential Moderators Between Trauma,Posttraumatic Stress,Depression, and Relationship Quality Among Emerging Adults

Exercise and diet have not been examined as potential protective factors between trauma and trauma-related sequelae. Using data collected from emerging adults (N = 321), we tested a path analysis to determine if exercise and diet would moderate the association between the number of potentially traumatic life events experienced and posttraumatic stress, depression, and relationship quality. More exercise was directly associated with higher posttraumatic stress and depressive symptoms. A healthier diet was directly associated with lower posttraumatic stress, lower depressive symptoms, and higher relationship quality. Results suggest there may be value in highlighting exercise and diet in family therapy.     

Relationship Between Religious Coping and Suicidal Behaviors Among African American Adolescents

This study investigated whether hopelessness and depression were risk factors for suicidal thoughts and behaviors in African American adolescents and looked at whether religious participation and religious coping protected these students from suicidality. Participants were 212 African American high school students (133 females, 79 males). The results of multiple and logistic regression analyses found that hopelessness and depression were risk factors for suicidal ideation and attempts. Religious coping style was significantly related to suicidal behaviors: Self-directed coping was related to increased hopelessness, depression, and suicide attempts, and collaborative coping was related to increased reasons for living. Gender differences were found in symptoms of depression, religious coping style and religious participation. Results provide additional support for suicide interventions to target hopelessness and depressive symptoms and highlight the importance of examining the role of culturally salient variables, such as religious participation and religious coping style, when developing intervention programs for suicide.     

Reports of attempted suicide among Brazilian addicts

Both substance dependence and depressive mood seem to be associated with increased suicide risk. Clinical information on suicide attempts and depressive symptoms were obtained from a sample of 211 psychoactive substance dependents attending a university clinic program for addicts in Brazil. 49 subjects (23.4%) had attempted suicide at least once, and the frequency of reporting attempts was 4.32 times greater among women than among men. Male addicts also tended to engage in potentially more dangerous attempt methods than women. Depressive male addicts were 2.17 times more likely to have attempted suicide than nondepressive addicted men. Among women, no association could be established between having attempted suicide and the presence of depression. Substance addicts have a relatively high risk of attempting suicide and the co-occurrence of depression seems to increase prevalence of suicidal behavior among men.     

Childhood Abuse,the Interpersonal–Psychological Theory of Suicide,and the Mediating Role of Depression

Although childhood abuse is a well‐known risk factor for suicide, no studies have investigated the role of interpersonal–psychological (Joiner, 2005), constructs in this association. This study examined whether childhood physical, sexual, and emotional abuse were associated with IPTS constructs, and whether depressive symptoms mediated these associations. Ninety‐one participants completed self‐report measures. Emotional abuse predicted perceived burdensomeness and thwarted belongingness, and depressive symptoms mediated these associations. Physical abuse predicted the acquired capability for suicide, although depression did not mediate this association. These findings suggest that specific types of abuse differentially predict IPTS components and underscore depression as a potential mechanism.     

The Association Between Anhedonia,Suicide Ideation,and Suicide Attempts: A Replication in a Persian Student Sample

Research suggests that anhedonia, a common symptom of depression, may be uniquely associated with suicidal behavior. However, little research has examined this association across cultures. To address this limitation, this study attempted to replicate a recent anhedonia and suicide study (conducted in a western culture) in a Persian sample using the Specific Loss of Interest and Pleasure Scale, Persian version. Participants consisted of 404 students who were recruited from a Persian university. Surprisingly, our results indicated that anhedonia levels were more than double those found in similar American student sample. Despite this marked difference in anhedonia symptoms, we found that anhedonia was associated with suicide risk, even when it was statistically accounting for other depressive symptoms. These findings suggest that anhedonia is a robust predictor of suicide risk across these two cultures. Further, anhedonia may be a particularly important treatment target among Persian students.     

Relationships Among Sleep Disturbance,Reward System Functioning,Anhedonia, and Depressive Symptoms

Recent models propose reward system dysfunction as a key mediator of the relationship between sleep and depression and anhedonia. This study explored interrelationships among sleep disturbance, depressive symptoms, anhedonia, and reward responsiveness. Two-hundred and sixty undergraduate students completed questionnaires and a daily diary paradigm assessing sleep, reward responsiveness, depression, anhedonia, and positive affect over 1 week. Baseline sleep disturbance was associated with depressive symptoms, anhedonia, and reward responsiveness. Daily diary sleep parameters showed differential associations with anticipatory versus consummatory reward responsiveness and positive affect. Poorer sleep quality, shorter sleep duration, and longer awakening after sleep onset predicted blunted anticipatory and consummatory reward responsiveness, while increased sleep onset latency and lower sleep efficiency predicted only decreased consummatory reward responsiveness. All sleep indices, except sleep onset latency, were associated with positive affect. Findings demonstrate unique associations between disparate sleep disturbance and reward responsiveness elements, highlighting new treatment mechanisms for anhedonia and depression.     

Mediators of the Daily Hassles–Suicidal Ideation Link in African American Women

Depressive symptoms and hopelessness as mediators of the daily hassles–suicidal ideation link in low‐income African American women exposed to intimate partner violence (n = 100) were investigated. As hypothesized, daily hassles, depressive symptoms, and hopelessness were each significantly and positively associated with suicidal ideation. Moreover, the relation between daily hassles and suicidal ideation was, in part, accounted for by depressive symptoms and hopelessness. This study demonstrates the importance of assessing for the presence of these risk factors when determining the likelihood that an abused African American woman will consider suicide. The findings further highlight the value of designing and implementing interventions that target the reduction in depressive symptoms and hopelessness in abused African American women exposed to daily hassles to reduce their suicide risk.     

Suicidality as a function of impulsivity, callous-unemotional traits, and depressive symptoms in youth

Suicidality represents one of the most important areas of risk for adolescents, with both internalizing (e.g., depression, anxiety) and externalizing-antisocial (e.g., substance use, conduct) disorders conferring risk for suicidal ideation and attempts (e.g., Bridge, Goldstein, & Brent, 2006). However, no study has attended to gender differences in relationships between suicidality and different facets of psychopathic tendencies in youth. Further, very little research has focused on disentangling the multiple manifestations of suicide risk in the same study, including behaviors (suicide attempts with intent to die, self-injurious behavior) and general suicide risk marked by suicidal ideation and plans. To better understand these relationships, we recruited 184 adolescents from the community and in treatment. As predicted, psychopathic traits and depressive symptoms in youth showed differential associations with components of suicidality. Specifically, impulsive traits uniquely contributed to suicide attempts and self-injurious behaviors, above the influence of depression. Indeed, once psychopathic tendencies were entered in the model, depressive symptoms only explained general suicide risk marked by ideation or plans but not behaviors. Further, callous-unemotional traits conferred protection from suicide attempts selectively in girls. These findings have important implications for developing integrative models that incorporate differential relationships between (a) depressed mood and (b) personality risk factors (i.e., impulsivity and callous-unemotional traits) for suicidality in youth.     

Depressive Symptoms and Suicide Risk in Older Adults: Value Placed on Autonomy as a Moderator for Men but Not Women

Risk for suicide is elevated among older men. We examined whether value placed on autonomy amplifies the relation between depressive symptoms and suicide risk differently for older men and women. Participants were 98 community‐dwelling older adults, M age 73.6 (SD = 8.6), 65.1% female, 93.1% White. Questionnaires measured suicide risk (SBQ‐R), depressive symptoms (CESD), and value placed on autonomy (PSI‐II autonomy). Among men, depressive symptoms were associated with suicide risk only when PSI‐II autonomy was elevated. Among women, greater depressive symptoms were associated with suicide risk at all levels of PSI‐II autonomy. Further research on attitudes toward autonomy is warranted.

Shame,Guilt, and Suicide Ideation among Bondage and Discipline,Dominance and Submission,and Sadomasochism Practitioners: Examining the Role of the Interpersonal Theory of Suicide

To date, no study has examined rates of suicide ideation or theory‐based risk factors for suicide ideation among bondage and discipline, dominance and submission, and sadomasochism (BDSM) practitioners. Participants were 321 adults that endorsed BDSM involvement. Thirty‐seven percent of the sample indicated a nonzero level of suicide ideation. Thwarted belongingness and perceived burdensomeness (PB) were positively associated with suicide ideation and their interactive effect predicted additional variance in suicide ideation after adjusting for depressive symptoms. Overall, shame and guilt were positively associated with suicide ideation and these relations were mediated by thwarted belongingness and PB in parallel adjusting for depressive symptoms; however, there were some differences between demographic subgroups. Among BDSM practitioners, stigma‐related internalized feelings (i.e., shame and guilt) may be associated with increased thwarted belongingness and PB, which are associated with suicide ideation.     

Obstructive sleep apnea and depression

Is there an association between obstructive sleep apnea (OSA) and depression? OSA is a common breathing-related sleep disorder. There have been reports that depressive symptoms can be associated with this sleep disorder. A number of investigations have addressed this issue. Although some have found no correlation, most studies have concluded that there is an association between OSA and depressive symptoms. Other investigations have shown that depressive symptoms improve with treatment of OSA, and that untreated OSA may contribute to treatment resistance in some cases of mood disorders. Within the framework of current psychiatric diagnostic criteria, the depressive symptoms associated with OSA can be viewed as a combination of a mood disorder secondary to a primary medical condition and an adjustment disorder with depressed mood. The question of whether OSA causes depressive symptoms can perhaps be best answered by viewing OSA and depression as having certain symptoms that are common to both disorders.     

Integrating the Interpersonal Psychological Theory of Suicide Into the Depression/Suicidal Ideation Relationship: A Short-Term Prospective Study

We examined the hypothesis that depressive symptoms are associated with increased beliefs about perceived burdensomeness and thwarted belongingness identified in the interpersonal psychological theory of suicide and that these beliefs are associated with changes in suicidal ideation. Participants with clinical levels of depressive symptoms (n = 299) were selected from a larger group (n = 508) and completed measures of depressive symptoms, perceived burdensomeness and thwarted belongingness, and suicidal ideation twice over a period of 2 months. Results of a structural equation model found that depressive symptoms were associated with increases in burdensomeness and lack of belonging, which were associated with suicidal ideation. Moreover, this hypothesized integrated model demonstrated a significantly better fit than an alternative model that assumed burdensomeness and lack of belonging were associated with changes in depressive symptoms, which were associated with suicidal ideation. Our findings suggest that the well-established relationship between depressive symptoms and suicidal ideation is associated with changes in beliefs that one is a burden on others and lacks belonging. More generally, these results suggest that it may be fruitful to integrate theories of suicide risk to form a comprehensive model that can inform future research and clinical interventions.     

Suicide schema in schizophrenia: the effect of emotional reactivity, negative symptoms and schema elaboration

Suicide risk is thought to increase with a greater potential for activation of suicide-related schemas. Suicide schemas are less likely to be activated with reductions of emotional range associated with certain negative symptoms of schizophrenia. The study tested whether suicide risk would increase in patients with recent onset schizophrenia with increased potential for suicide schema activation as indicated by lower levels of specific negative symptoms that reflected emotional reactivity, namely emotional withdrawal and blunted affect. A logistic regression analysis of baseline data of 278 recent onset schizophrenic patients with a measure of suicide behaviour as the dependent variable and negative symptoms, delusions, hallucinations, depression, gender, episode, ethnicity, education, age, duration of untreated psychosis and substance use as independent variables was carried out. Emotional withdrawal, but not blunted affect was significant and negatively associated, and depression positively associated with suicide behaviour. There was evidence to indicate that restricted emotions are associated with reduced suicide risk as predicted.     

Violence Exposure, Sleep Disturbance, and Poor Academic Performance in Middle School

Violence has been linked to poor academic outcomes in youth, but there is little understanding of the mechanisms underlying this relation. This longitudinal survey study investigated whether sleep disturbance potentially mediates the associations between academic achievement and two forms of violence exposure--community violence and peer victimization-- in 498 seventh-grade youth. Structural equation models showed that community violence was associated with lower grade point average (GPA) directly and indirectly via sleep problems, whereas peer victimization was associated with lower GPA just indirectly via sleep problems. The structural models controlled for potential confounds, including depressive symptoms, intrusive thoughts and absenteeism. The findings suggest that failing grades and sleepiness in school may be signs that youth are exposed to violence. Interventions to improve sleep hygiene and reduce violence exposure may help to improve academic outcomes for youth.
