Comparing diagnostic criteria for posttraumatic stress disorder in a diverse sample of trauma-exposed youth

Divergent conceptualization of posttraumatic stress disorder (PTSD) within the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) and International Statistical Classification of Diseases and Related Health Problems (11th ed..; ICD-11) significantly confounds both research and practice. Using a diverse sample of trauma-exposed youth (N = 1,542, age range: 8-20 years), we compared these two diagnostic approaches along with an expanded version of the ICD-11 PTSD criteria that included three additional reexperiencing symptoms (ICD-11+). Within the sample, PTSD was more prevalent using the DSM-5 criteria (25.7%) compared to the ICD-11 criteria (16.0%), with moderate agreement between these diagnostic systems, κ = .57. The inclusion of additional reexperiencing symptoms (i.e., ICD-11+) reduced this discrepancy in prevalence (24.7%) and increased concordance with DSM-5 criteria, κ = .73. All three PTSD classification systems exhibited similar comorbidity rates with major depressive episode (MDE) or generalized anxiety disorder (GAD; 78.0%-83.6%). Most youths who met the DSM-5 PTSD criteria also met the criteria for ICD-11 PTSD, MDE, or GAD (88.4%), and this proportion increased when applying the ICD-11+ criteria (95.5%). Symptom-level analyses identified reexperiencing/intrusions and negative alterations in cognition and mood symptoms as primary sources of discrepancy between the DSM-5 and ICD-11 PTSD diagnostic systems. Overall, these results challenge assertions that nonspecific distress and diagnostically overlapping symptoms within DSM-5 PTSD inflate comorbidity with depressive and anxiety disorders. Further, they support the argument that the DSM-5 PTSD criteria can be refined and simplified without reducing the overall prevalence of psychiatric diagnoses in youth.

Evaluating traumatic event scoring schemas for their predictive value to concurrent diagnostic profiles: Texas Childhood Trauma Research Network

BACKGROUND

To prospectively chart pathways of risk and resiliency following childhood trauma studies need to address three limitations of prior work: 1) recruit beyond social service/ treatment settings; 2) include broad spectrum of trauma types and 3) cast a broad longitudinal measurement framework of both clinical diagnoses and traumatic exposures. The Texas-Childhood Trauma Research Network (TX-CTRN) is a multi-site collaboration that addresses these limitations. In this baseline-only report, we examined domains of trauma and evaluated the concurrent predictive validity of various traumatic event scoring schemas for clinical diagnoses.

METHODS

Broad-base recruitment of 8-20 year-olds (N = 1289) included trauma centers, emergency departments, pediatric and primary care clinics, and other community settings. Assessments were comprehensive and based on clinical interviews by trained research interviewers.

RESULTS

Factor analyses supported a five-factor solution of trauma domains including unintentional/acute, intentional/interpersonal, bullying, in-home versus community witnessed interpersonal harms. Trauma burden scoring schemas were examined for their predictive superiority. Domain-specific counts of traumas that met DSM-5 post-traumatic-stress disorder (PTSD) Criterion-A was the best overall schema in distinguishing among youth with no diagnosis, comorbidities, those with depression, suicidality, substance misuse, and PTSD.

LIMITATIONS

There were no assessments of neglect.

CONCLUSIONS

Findings largely aligned with earlier studies on the relative importance of intentional interpersonal traumas and showed bullying may be an important source of traumatic stress that independently adds to prediction of several diagnoses and should be considered in clinical practice.

Characterizing patterns of substance use in trauma exposed youth

OBJECTIVE

Previous work investigating the impact of childhood trauma on substance use and co-occurring psychiatric disorders has primarily been conducted in adults or on specific trauma types. This limits understanding of traumas impact in childhood and how different types of traumas play a role. We sought to characterize substance use in a sample of trauma-exposed youth in the context of psychiatric comorbidities.

METHOD

1152 youth from the Texas Childhood Trauma Research Network (TX-CTRN) that were exposed to at least one trauma meeting DSM-5 Criterion A were assessed for current substance use and psychiatric diagnoses. Latent class analysis was used to identify patterns of substance use. To characterize these patterns, we examined if demographics, number of trauma types experienced, or childhood psychiatric disorders predicted class membership.

RESULTS

We identified four primary patterns of substance use: Non-use (66.1%), predominantly alcohol use (19.7%), predominantly cannabis use (4.5%), and polysubstance use (9.7%). Compared to the non-users, polysubstance users tended to be older, Non-Hispanic White, have experienced more types of trauma. They were also more likely to have fulfilled diagnostic criteria for suicidality and ADHD. Comparisons among the substance using classes were more nuanced.

CONCLUSION

The findings highlight the need for universal assessments of trauma, substance misuse, and mental health symptoms in youth as the presence or absence of their co-occurrence has implications for treatment.

Prevalence and correlates of externalizing behaviors among youth seeking treatment following trauma exposure

OBJECTIVE

Trauma-exposed youth often experience impairing externalizing problems (EXTs), yet the relationship between EXTs, trauma exposure, and posttraumatic stress symptoms (PTSS) are not well understood. To examine the extent of their co-occurrence, we report the rates and correlates of youth EXTs relative to clinically elevated PTSS in a sample of youth referred to a trauma and grief specialty clinic.

METHOD

Self- and caregiver-report measures were obtained from 260 youth ages 7-19 years (M = 11.92, SD = 3.21; 53.5% female) during a pretreatment assessment. The sample was divided into 4 groups according to the youths' PTSS and EXT score elevations, and these groups were then compared according to rates of youth depressive symptoms, youth suicidal ideation, and caregiver strain.

RESULTS

The 4 groups were comorbid PTSS and EXTs (18%); EXTs-only group (36%); PTSS-only group (13%), and subclinical symptom group (34%). The comorbid PTSS and EXTs group had the highest scores on all other child and caregiver symptom measures. Compared to the subclinical group, youth in the PTSS-only group had increased depressive symptoms and suicidal ideation, whereas youth in the EXTs-only group had elevated levels of caregiver strain.

CONCLUSION

Co-occurring PTSS and EXTs is a common presentation among trauma-exposed youth referred to treatment. These youth are also likely to suffer from other problems of clinical concern, including suicidal ideation, and their problems are associated with caregiver distress. More research is needed to examine unique risk and resiliency factors related to the development of youth EXTs in response to trauma exposure.

Comfort Expressing Emotions and Suicide Ideation: Evidence of Indirect Effects Via Perceived Burdensomeness and Thwarted Belongingness

OBJECTIVE

Emotion regulation strategies and related constructs have been implicated both as risk and protective factors in a range of mental health outcomes among young adults. To expand upon this previous research, we examined comfort expressing four discrete emotions (i.e., love, happiness, sadness, and anger) as factors that protect against suicide ideation in young adults, within the context of the interpersonal theory of suicide.

METHOD

The sample consisted of 449 college students (73.1% female, 70.6% Hispanic, Mage = 20.5 years) taking part in a larger study of mood and well-being. Students were recruited from a psychology participant pool and completed self-report measures at a single time point for course credit. Comfort expressing emotions and suicide ideation were assessed using the Measure of Verbally Expressed Emotion (MoVEE) and Adult Suicidal Ideation Questionnaire (ASIQ), respectively. Perceived burdensomeness and thwarted belongingness were assessed using the Interpersonal Needs Questionnaire (INQ).

RESULTS

Preliminary analyses revealed negative associations between comfort expressing all four emotions and suicide ideation (rs = -.13 to -.26). Results from structural equation modeling supported indirect effects from comfort expressing happiness and sadness to suicide ideation, via perceived burdensomeness and thwarted belongingness. An indirect effect was also identified from comfort expressing love to suicide ideation, via thwarted belongingness.

CONCLUSIONS

Results suggest that comfort expressing emotions (particularly sadness and happiness) is a protective factor against suicide ideation for young adults. These findings suggest that suicide-prevention efforts may wish to focus on increasing comfort expressing emotions to trusted support networks as potential intervention targets.HIGHLIGHTSComfort expressing emotions is negatively associated with suicide ideation.Comfort expressing emotions is associated with belongingness and burdensomeness.Comfort expressing emotions may be a potential target for suicide prevention.

Geospatial identification of high youth suicide risk areas via electronic health records: Avenues for research and prevention efforts

OBJECTIVE

As suicide risk screening becomes more common in healthcare settings, geospatial coding of behavioral health data may offer a means for identifying areas of elevated suicide risk for use in public health prevention efforts. The present study demonstrates an analytic approach for using universal suicide risk screening data to identify areas of elevated suicide risk.

METHOD

Data were drawn from standard suicide risk screens recorded in electronic health records of a large pediatric emergency department. A total of 12,400 suicide risk screening responses were recorded, among youth aged 11-19 years (mean = 14.60, SD = 2.16; 57.2% girls, 47.8% Hispanic/Latinx, 72.1% White). A total of 86 unique ZIP codes had at least 50 completed screens, representing 9139 respondents.

RESULTS

Rates of positive screens ranged from 6.17% to 31.03% (mean = 18.33, SD = 5.14) for any suicide-related behavior and from 0.0% to 19.61% (mean = 9.14, SD = 3.43) for suicide attempt. Rates of positive screens approximated a normal distribution.

CONCLUSIONS

Results demonstrated several areas with elevated rates of positive suicide risk screens, within the hospital catchment area. The proposed method capitalizes on large-scale screening data, provides an estimate of areas of relative increased risk, and may be used to inform public health responses to suicide prevention.

Performance of the interpersonal needs questionnaire in adolescent clinical samples: Confirmatory factor analyses and evaluation of measurement invariance

OBJECTIVE

This study evaluated the factor structure, internal consistency reliability, construct and criterion validity, and measurement invariance of the Interpersonal Needs Questionnaire (INQ) among adolescents.

METHOD

Participants (N = 539) included three distinct samples of youth drawn from two outpatient psychology clinics and an inpatient psychiatric unit. The combined sample was 63.3% female and had a mean age of 14.95 years (SD = 1.31 years). All participants completed the INQ as well as measures of depressive symptoms and suicide ideation.

RESULTS

Confirmatory factor analyses indicated that the removal of three items from the thwarted belongingness subscale of the INQ was needed to achieve acceptable model fit. The resulting combined 12-item scale demonstrated good factor structure, internal consistency reliability, construct validity, and criterion validity. The modified 12-item INQ also demonstrated scalar invariance across subgroups defined by sex, race, and age.

CONCLUSIONS

Findings support the use of this reduced 12-item version of the INQ among adolescents. Youth may have difficulty accurately responding to changes in item valence; thus, future research with youth should consider using a 12-item version of the INQ that avoids valence changes within subscales.

Caregiver behaviors and childhood maladaptive grief: Initial validation of the Grief Facilitation Inventory

The Grief Facilitation Inventory (GFI) is a newly-developed measure of caregiver behaviors theorized to facilitate or hinder children's adaptive grief reactions. We examine its factor structure, reliability, and validity. An exploratory factor analysis identified four factors: Ongoing Connection, Existential Continuity/Support, Caregiver Grief Expression, and Grief Inhibition/Avoidance. Both child- and caregiver-report versions had adequate-to-good internal consistency. The child-report GFI showed evidence of criterion-referenced validity via significant correlations with measures of child maladaptive grief and other psychological symptoms. Results provide preliminary evidence of the reliability, validity, and clinical utility of the GFI as a measure of caregiver grief-facilitation behaviors.

Assessment of prescription stimulant misuse among college students using the MMPI-2-RF

Prescription stimulant misuse (PSM) is a growing concern on college campuses and more research is needed to validate clinical measures commonly used for the assessment of risk for PSM among college students. The present study examined correlations between scores on the Minnesota Multiphasic Personality Inventory-Second Edition-Restructured Form (MMPI-2-RF) and self- and peer-reported misuse of prescription stimulants and other drugs in a sample of 96 pairs (included within a total N = 212) of undergraduate students. Nearly half of the participants (48%) reported that they had been offered prescription stimulants and one quarter (26%) reported trying someone else's prescription stimulant medications, often to perform better academically. Scores on the MMPI-2-RF scales designed to measure general substance misuse (Substance Abuse [SUB]) and related behavioral or externalizing constructs (e.g., Antisocial Behavior [RC4], Behavioral/Externalizing Dysfunction [BXD], and Disconstraint-Revised [DISC-r]), were correlated positively with both self- and peer-reported prescription stimulant misuse (rs = 0.45-0.66), as well as with problematic use of other drugs (rs = 0.44-0.63). MMPI-2-RF scales designed to measure constructs in the domains of Emotional/Internalizing, Somatic/Cognitive, and Thought Dysfunction, as well as Interpersonal Functioning, had weaker correlations with misuse of prescription stimulants (rs < 0.24) and other drugs (rs < 0.29). These results provide support for the convergent validity of the MMPI-2-RF with regard to the assessment of prescription stimulant misuse and general drug misuse among college students.

Initial Validation and Measurement Invariance of the Active Inhibition Scale Among Traumatized and Grieving Youth

The Active Inhibition Scale (AIS; Ayers, Sandler, & Twohey, 1998) is an 11-item, self-report measure of emotional suppression among children and adolescents. Previous research with the AIS has linked emotional suppression to several clinically significant outcomes, such as posttraumatic stress symptoms (PTSS) and suicide, among trauma-exposed and bereaved youth; however, there are no published evaluations of its psychometric properties. We examined the factor structure and criterion validity of the AIS in two samples. Sample 1 included youth (M = 12.22 years, SD = 2.96, range: 6-18 years; 55.4% female) referred to an outpatient psychology clinic specializing in childhood trauma and grief. Sample 2 included youth (M = 13.18 years, SD = 2.58, range: 8-18 years; 61.8% female) referred to a community grief counseling center. Confirmatory factor analytic results supported a one-factor solution, Cronbach's α = .94. Additionally, AIS scores correlated positively with PTSS, depression, and maladaptive grief, rs = .43-.64. Evidence of factorial invariance was found across gender, race/ethnicity, and age group. Emotional suppression scores were higher among girls compared to boys, Black and Hispanic youth compared to White youth, and older compared to younger age groups. The magnitude of correlations between AIS and symptom measure scores was comparable across groups. These results support the reliability and criterion validity of the AIS with diverse youth populations and underscore the role that emotional suppression may play in explaining group differences in mental health symptoms.

Suicide Safety Planning: Clinician Training, Comfort, and Safety Plan Utilization

Extant literature has demonstrated that suicide safety planning is an efficacious intervention for reducing patient risk for suicide-related behaviors. However, little is known about factors that may impact the effectiveness of the intervention, such as provider training and comfort, use of specific safety plan elements, circumstances under which providers choose to use safety planning, and personal factors which influence a provider’s decision to use safety planning. Participants were (N = 119) safety plan providers who responded to an anonymous web-based survey. Results indicated that most providers had received training in safety planning and were comfortable with the intervention. Providers reported that skills such as identifying warning signs and means safety strategies were routinely used. Providers who reported exposure to suicide were more likely to complete safety plans with patients regardless of risk factors. In addition, almost 70% of providers indicated a need for further training. These data provide important considerations for safety plan implementation and training.

A Comparison of the Descriptive Information from the MMPI-2 and MMPI-2-RF

Do MMPI-2 or MMPI-2-RF profiles differ in how accurately they depict examinees? To explore this question, we examined differences in clinical descriptions of equivalent profiles from the two instruments. Fourteen valid MMPI-2 protocols from an archival private practice sample were scored as both the MMPI-2 and the MMPI-2-RF. The resulting 28 profiles were coded separately by four raters using the Midwestern Q-Sort. Examinee descriptions from the two instruments were compared in terms of their (a) similarity, operationalized by q-correlations between corresponding MMPI-2 and MMPI-2-RF ratings; (b) descriptive validity, operationalized by correlations with q-sorts provided by the examinees' therapists; and (c) incremental descriptive validity, operationalized by incremental prediction of the therapist q-sorts by the MMPI-2 and MMPI-2-RF, one over the other. Descriptions from corresponding MMPI-2 and MMPI-2-RF score reports were highly intercorrelated. Ratings from both were valid predictors of therapist descriptions, and neither clearly outperformed the other in terms of incremental validity.
