Masculine gender-related personality traits and acquired capability for suicide.

In most countries, substantially more men than women die by suicide, implicating masculine gender-related personality (MGP) traits as a risk factor for suicide. The Interpersonal Theory of Suicide posits that acquired capability for suicide (ACS) is needed to end one's life. To investigate MGP traits and ACS, college students (N = 149) completed measures of stoicism, sensation seeking, physical aggression, and ACS. For both genders, most MGP traits were associated with increased ACS. Physical aggression mediated relations between both stoicism and sensation seeking and ACS, but gender did not moderate these associations, suggesting similar patterns for men and women.

The effects of blood in self-injurious cutting: Positive and negative affect regulation.

OBJECTIVE: Seeing one's own blood may be a factor in affect regulation in nonsuicidal self-injury (NSSI). This study examined changes in a negative (NA) and positive affect (PA) in response to a finger prick eliciting a small drop of participants' blood. METHODS: Two groups (NSSI; N = 56 and Control; N = 70) of undergraduate students were randomly assigned to receive a finger prick and look at blood, receive a finger prick and not look at blood, or receive a sham finger prick. Following a mood induction, participants completed the PANAS three times: Time 1 (pre mood-induction, baseline), Time 2 (post-mood induction), and Time 3 (post-finger prick condition), and a Pain Severity Scale. RESULTS: A significant three-way interaction revealed that the NSSI: Blood Group had an increased positive effect between Time 2 and Time 3. CONCLUSION: Blood serves an important function in NSSI and requires additional research to fully understand the relationship.

Moderating effects of brooding on the link between functional impairment and interpersonal needs in survivors of serious trauma.

OBJECTIVES: Trauma and resulting functional limitations demonstrate associations with perceived burdensomeness and thwarted belongingness, factors contributing to elevated risk for suicidal ideation. However, survivors display differential risk in response to impairment, highlighting the need for research on exacerbating factors. The current study examined the impact of brooding on the association of functional impairment with burdensomeness and belongingness among trauma-exposed undergraduates (N = 262). METHOD: Trauma was assessed via clinical interview with questionnaires for study variables. Regression models examined the unique and interactive effects of physical impairment, emotional impairment, and brooding on burdensomeness and thwarted belongingness. RESULTS: An interaction of brooding and impairment due to emotional difficulties was observed for burdensomeness with impairment linked to elevated burdensomeness at high (ß = -0.46; p < 0.001), but not low (ß = -0.07; p = 0.476) brooding. Impairment due to emotional difficulties (ß = -0.38; p < 0.001) and brooding (ß = 0.25; p < 0.001) were associated with belongingness. CONCLUSIONS: Findings identify brooding as a potential target for assessment and intervention in trauma-exposed individuals.

The Effect of Zero Gravity on Eyelid and Brow Position.

PURPOSE: To describe the effect of spaceflight on upper eyelid and brow position. MATERIALS AND METHODS: Images of astronauts on earth and in space were collected from a National Aeronautics and Space Administration image library. For each astronaut, front facing portraits captured within a 5-year period were obtained. At least 6 photos were collected per astronaut, 3 taken on earth, and 3 in zero gravity. Measurements from the center of the pupil to the upper eyelid margin (MRD1) and center of the pupil to the inferior eyebrow margin [pupil-to-brow (PTB)] were performed digitally for each image and averaged for each condition and each individual. Differences in mean MRD1 and PTB were assessed to illustrate the effects of zero gravity on eyelid and eyebrow position respectively. Linear-mixed effects modeling, analysis of variance and post hoc power analysis were performed. RESULTS: One hundred and twelve photographs (55 earth, 57 space) from 18 astronauts (4 women, 14 men; mean age 45.9 years) were retrieved. Zero gravity resulted in a mean PTB increase of 3.7 mm (p < 0.01) but did not result in significant change in MRD1 (p = 0.21). Post hoc power analysis of the measured MRD1 difference was performed by simulation. At an MRD1 difference of 0.5 mm, the probability of a type II error is 2.6%, equivalent to a beta power of 97.4%. Thus, we can be 97.4% confident that a difference in MRD of 0.5 mm or greater would be detected. CONCLUSIONS: While spaceflight led to significant elevation of PTB, it did not consistently alter MRD1. As such, the brow and eyelid appear to be independently regulated with respect to gravitational changes.

Exploring the relation between posttraumatic stress disorder and interpersonal outcomes: The role of social acknowledgment and trauma type.

OBJECTIVES: Research demonstrates consistent relations between posttrauma symptoms and interpersonal dysfunction. The current study examined the extent to which perceptions of community rejection account for the relation between posttraumatic stress disorder (PTSD) and interpersonal outcomes in students exposed to assaultive and nonassaultive trauma. METHOD: Participants (N = 137; 66.4% female; M = 20 years) completed a trauma history interview, questionnaires assessing symptom severity, social disapproval, and interpersonal outcomes. RESULTS: Assault survivors (n = 83) reported greater symptoms (d = 0.57), disapproval (d = 0.80), and social impairment (d = 0.51) relative to the nonassault group (n = 54). However, regression analyses indicated stronger associations between PTSD and community disapproval in survivors of nonassaultive (ß = 0.69; p < 0.001) versus assaultive (ß = 0.34; p < 0.001) events. Indirect effects of PTSD on perceived support and interpersonal functioning through social disapproval were also larger for nonassaultive versus assaultive groups (p < 0.05). CONCLUSION: Despite greater dysfunction among assault survivors, perceptions of disapproval may be a more salient factor for interpersonal dynamics following nonassaultive trauma.

Interpersonal needs and suicide risk: The moderating roles of sex and brooding.

OBJECTIVES: This paper tested two moderators, brooding and participant sex, on the respective relations between thwarted belongingness (TB), perceived burdensomeness (PB), and suicide risk. METHOD: Using a cross-sectional design in a sample of undergraduates (N = 278), two hierarchical regression models examining the three-way interaction between brooding, sex, and either TB or PB on suicide risk were conducted. RESULTS: A significant two-way interaction of brooding and TB was detected, but no moderating effect of sex was observed. There was a significant three-way interaction of brooding, sex, and PB on suicide risk. CONCLUSIONS: High levels of TB and brooding produce increased suicide risk across sexes. The relation between PB and suicide risk is dependent on brooding for females but not males.

Before, During, and After Self Injury: The Practice Patterns of Nonsuicidal Self Injury.

Little is currently known about the repetitive behaviors that take place before, during, and after nonsuicidal self-injury (NSSI). These practice patterns surrounding repetitive self-injury may be part of a habituation process in NSSI. Congruent with the opponent process theory (OPT), the mechanisms through which NSSI is reinforced may include preparation, engagement, and follow-up practice patterns to achieve the desired effect. This may result in increased habituation leading to a change in method and resulting NSSI severity. College students with a history of NSSI (N = 80) completed questionnaires, including an instrument to assess practice patterns around NSSI. High levels of NSSI practice patterns were positively related to various NSSI characteristics and clinical correlates, suggesting higher levels of NSSI severity. Further, NSSI versatility partially explained the relationship between NSSI practice patterns and habituation. Consistent with OPT, practice patterns associated with repetitive NSSI may lead an individual to change methods, fostering habituation to self-injury.

Interpersonal needs and psychological pain: The role of brooding and rejection sensitivity.

The interpersonal theory of suicide proposes that thwarted belongingness (TB) and perceived burdensomeness (PB) predict psychological pain and desire for suicide. Brooding may be a mechanism in explaining how TB and PB predict pain. The conceptual similarity between rejection sensitivity (RS) and TB suggests that individuals with high RS may be likely to experience psychological pain in the context of TB. To test this model, 155 college students completed measures of psychological pain, TB, PB, brooding, and RS. As predicted, brooding mediated the relations between both TB and PB and psychological pain. RS interacted with TB in predicting psychological pain.

Therapeutic Risk Management for Violence: Safety Planning for Other-directed Violence.

Therapeutic management of risk for other-directed violence (ODV) involves screening, assessment, and clinically appropriate intervention. In this 5-part series, effective screening and assessment for ODV have been described as a combination of clinical interviewing and the use of structured tools to inform clinical impressions of both acute and chronic risk for violence. Once risk of violence is identified, therapeutic management of the risk throughout the course of treatment is best achieved by determining the function of the violent ideation and behavior. This can be achieved through the use of functional chain analysis. Chain analysis not only serves the purpose of providing insight into the contingencies of violent behavior but also helps to identify target areas of intervention where other skills, strategies, and means to access resources for support can be applied. In this fifth and final column of the series, we describe an intervention with all of these outcomes as its goals. A safety plan for ODV assists both clients and mental health professionals in disrupting patterns of violent ideation or behavior that would otherwise continue causing not only harm to others but prolonged negative consequences for those engaging in such behaviors.

Differential suicide risk factors in rural middle and high school students.

Few studies have examined risk factors associated with suicidal ideation and attempts among younger adolescents compared to their high-school aged counterparts. To gain a better understanding of unique risk factors associated with suicidal ideation and attempts among middle-school aged students, the current study employed secondary data analyses on a statewide sample of middle school (6th and 8th grade; n = 7,453) and high school students (10th and 12th grade; n = 5,996) in the United States. Logistic regression analyses were used to determine the effects of fourteen empirically derived risk factors on odds of reporting suicidal ideation (SI) and suicide attempts (SA) in the past year. Results indicated unique factors associated with risk for SI and SA among middle and high school students. For middle-school aged students, female sex, lower perceptions of school safety, sensation seeking, psychological distress, bullying victimization, early initiation of drug use, and community disorganization predicted past year SI. Female sex, white race, perceptions of school safety, bullying victimization, aggregate drugs used, psychological distress, and community disorganization predicted SA. Conversely, sex, age, perceptions of school safety, and community disorganization were not associated with suicidal behavior in high school students. Developmental explanations and avenues for future research are discussed.
